Description of the Invention: [Technical Field of the Invention] The present invention relates to a hand tool, and more particularly to a oscillating head wrench in which a head can be fixed at different angular positions. [Prior Art] The head of the conventional wrench is fixedly connected to the grip. In a narrow space or in some cases, the nut is fastened to a corner that is not easily accessible, and the conventional wrench is difficult to use. In order to solve this deficiency, the inventor has proposed the invention patent of No. 93102729 "Improved structure of tools" and the invention patent of "Folding structure of hand tools" No. 94136391, so that the handle of the wrench can be oscillated relative to the head so that In the narrow space use, the invention patent No. 93102729 has a perforation in the head of the wrench, and a tooth post is arranged at the front end of the handle, and the tooth column of the handle is inserted into the perforation of the head to make the tooth column and The teeth of the perforations are meshed and ready for use. When the angle between the head and the handle is to be changed, the handle is lifted upwards, and the tooth column is moved together by the handle, so that the tooth column and the perforation are no longer engaged, and the relative angle between the head and the handle can be adjusted. After adjustment, re-traverse the tooth column into the perforation, so that the tooth post and the perforation are twisted again, and the grip and the head are fixed at this angle. ❹ Patent No. 94136391 also has a perforation in the head of the wrench and a stud at the front end of the gripper, so that the teeth of the stud can be engaged with the teeth of the perforation when the stud is completely moved into the perforation. Keep the handle and head at a fixed angle. Similarly, when the handle is lifted up, the handle moves the column to disengage the teeth of the tooth post from the teeth of the tooth hole, so as to adjust the relative angle between the head and the handle. When the patent application is to adjust the relative angle between the head of the wrench and the handle, the handle must be moved, that is, the relative movement of the handle and the head can be released, and the engagement state between the head and the handle can be released. The operation method requires the use of both hands, holding the handle in one hand and fixing the head in the other hand, which is not convenient to use. SUMMARY OF THE INVENTION 3 201026440 can be easily released. The main object of the present invention is to provide a oscillating wrench, the engagement of the head of the hand with the grip. The oscillating weight wrench provided by the present invention has a handle and a head connected by a first and second ends to adjust the relative angle of the shank and the clevis; the first end has one of the maintaining intervals a first perforation and a crotch portion; a first perforation provided in the upper crotch portion of the upper crotch portion is disposed on the H end of the lower crotch portion, and between the two ends, the second end has a second perforation located at Between the first pupil and the through hole;

Thereby, the relative angle between the grip and the head can be adjusted by simply pressing the post. [Embodiment] In order to enable the reviewing committee to further understand the objects, features, and effects of the present invention, a preferred embodiment of the present invention will now be described in detail with reference to the drawings. The first figure is a perspective view of a preferred embodiment of the invention. The second drawing is an exploded perspective view of the first figure. The second figure shows the cross-sectional circle of the first end and the second end of the present invention. The fourth circle is a longitudinal sectional view of the first figure. The fifth figure is a partial enlarged view of the fourth 囷. The sixth picture is similar to the fourth one, showing that the post is moved down to a release position. The seventh figure is a partial top view of the first figure. Referring to the first and second figures, a first preferred embodiment of the wrench (1) provided by the present invention has a handle (12), and the two ends of the handle are connected to a head at each end ( 14). Each head (14) and the handle (12) are connected to a second end 4 201026440 (30) by a first end (2) and can be adjusted in relative angle. The first end (2〇) may be one end of the handle (I2) and the second end (3〇) may be one end of the head (14). It will be understood that the first end and the second end are interchangeable such that the first end (20) is one end of the head (14) and the second end is one end of the grip (12). The other end of the head (14) is a set of ends (16) for socketing the nut, and the socket end (16) can be an open end or a closed end (b〇x en(j) The closed end may be a polygonal sleeve hole 'the closed end may also be a ratchet structure' with a ratchet (as well); the socket end (16) may also have a protrusion (for example, the second patent No. 93102729) The icon number 25 is shown in the figure. 'It is used to insert the ferrule. The socket end is a conventional structure and will not be described. Please refer to the third 囷. The first end (2 〇) has a top ( (21) and a 垣The portion (22) is juxtaposed up and down, and a space (24) is formed between the one portion. A first perforation ¢ 5) is disposed on the upper crotch portion (22), and the peripheral wall has a plurality of teeth (26); a through hole (27) is provided in the lower jaw portion (22) and corresponds to the perforation (25). A limiting collar (28) is disposed on the wall of the through hole (27). The second end (30) is provided with a second perforation (32) having a plurality of teeth (34) on its peripheral wall. The first end (30) extends into the space (24) between the two jaws (21) (22). The first perforation (32) is located between the first perforation (25) and the through hole (27) and corresponds to each other. Further, in the present embodiment, the bottom edge of the second perforation (32) is not formed with a tooth and is formed as a hole portion (36), but the hole portion (36) is not an essential configuration. A column (40) is provided with a plurality of teeth (42) on the circumferential surface, and the teeth (42) are formed only on the top side surface of the post in this embodiment. In practice, the teeth (42) may be formed on the top side and the bottom side of the post, and are not limited to the top side. The post (4〇) is installed in the two perforations (25) (32) and the through hole (27), such as the fourth and fifth sides, so that the first end (20) and the second end (30) ) Produce a bond. The post (40) can be moved up to the position of the fifth figure, or moved down to one of the release positions shown in the sixth figure. In detail, the peripheral surface of the post is provided with a flange (44). The flange is formed by a C-shaped buckle and is fastened to the 5 201026440 ring groove (45) provided on the circumferential surface of the post. The outer diameter of the abutting edge (44) is greater than the inner diameter of the second perforation (32) of the second end (3), so that the abutting edge (44) can abut the bottom surface of the perforating hole (32), such as In the five figures, the perforations (25) (32) are not removed when the post is moved up. When the post (4〇) is moved down to the release position of the sixth figure, the collar (28) is abutted by the abutment (44) (or by the bottom wall of the tooth (42) against the flange (28) ), so that the post does not come out. At least one resilient member (46), for example, consisting of a spring and a steel ball, is embedded on the bottom side of the post and below the abutment (44). The elastic positioning member is elastically exposed on the peripheral surface of the post. When in use, please refer to the first and fifth figures. When the post (4〇) is in the clamping position, it penetrates into the first perforation (25) and the second perforation (32). The teeth of the post (42) At the same time, the teeth of the two perforations (25) (32) are engaged, so that the first end (2〇) and the second end (3〇) are meshed and fixed, and cannot rotate relative to each other. Thus, the nut can be rotated by the head (丨4) when the grip (12) is pulled. The resilient retaining member (46) of the post (40) abuts against the top surface of the collar (28) to maintain the post in the engaged position. Preferably, the abutment (44) simultaneously abuts against the bottom wall of the second end (30) so that the post does not sway up and down when it is in the engaged position. When the post (40) is pressed down and moved down to the release position of the sixth figure, the post (40) leaves the first perforation (25), at which time the post is only with the second perforation ( 32) The joint is not sprayed with the first perforation (25), and the first end (2〇) and the second end (3〇) are no longer engaged and fixed, and form a relatively rotatable state, the head (14) With the grip (12), the post (40) can be rotated relative to the center of rotation, as shown by the imaginary line of the seventh figure. After the head (14) is rotated to the desired angular position, the post (4〇) is pressed back to the position of the pinch of the fifth figure, so that the two ends (20) (30) can be re-bucked and fixed. The resilient retaining member (46) slides over the flange (28) when the post (40) is moved from the engaged position to the released position, or when the release position is returned to the engaged position. When the first end and the second end are released from the meshing state of the fifth figure to the released state of the sixth figure, it is only necessary to move the post (40) between the perforations (25) (32) without The handle and the head are relatively displaced. Therefore, the user can release the sound between the handle and the head by pressing the post (40) with the thumb of the hand holding the handle (12), in other words, 201026440, with one hand It is possible to release the card from the handle and the head. Furthermore, the structure of the present invention is simple: easy to operate, and the implementation of the engraving _ IX shows that the present invention (4) is not limited. In summary, the present invention is the first structure of the same kind of articles, and has the promotion of progressive effects, and is in line with the invention patent requirements, and submits an application according to law. The Pleasing Review Committee has been encouraging the Chinese people to innovate in their inventions, to take the time to examine them, and to grant patents as an early prayer. 201026440 BRIEF DESCRIPTION OF THE DRAWINGS The first drawing is a perspective view of a preferred embodiment of the present invention.
