Description

Open end wrench structure

The invention relates to an open-end wrench, in particular to an open-end wrench structure capable of operating different working pieces.

Wrench is one of the most widely used hand tools. It is used to lock or disassemble work pieces of various sizes, sizes and shapes, and to match different types of work pieces. There are also various kinds of wrenches for different purposes, such as open-end wrenches. Socket wrench, plum wrench.

Please refer to FIG. 1 , which is a conventional open-end wrench 1 , which is pivotally connected with an open-type driving head 2 , and the open-type driving head 2 faces the working piece (such as a hex nut) in parallel clamping. The two sides of the plane are formed to be clamped and fixed, and the open-type driving part 2 is controlled to pivotally rotate the workpiece to rotate, and the locking operation of the workpiece is achieved according to the rotation direction thereof, and the opening handle 1 is provided with a The ratchet portion 3 increases the degree of engagement with the workpiece.

However, due to the complicated working parts, even the working parts applied to the same machine usually exceed two or more specifications. Instead of using a single-size open-end wrench 1, the operation can be applied, as shown in Figure 2. Knowing the open-end wrench 4 of another size, the open-type driving head 5 of the open-end wrench 4 is significantly smaller in size than the open-type driving head 2 shown in FIG. 1 , and the open-end wrench 4 of this specification is a small working size. In other words, users often need to carry several kinds of open-end wrenches of different sizes, and can be used to operate work pieces of different specifications.

Therefore, how to overcome the conventional open-ended driving heads 2 and 5 of the open-end wrenches 1 and 4 is designed to have a fixed size, so that the user must carry at least one open-ended wrench of different specifications, and can operate different specifications. Work piece.

The object of the present invention is to provide an open-end wrench structure, which mainly utilizes the sleeve The first and second sets of space with different size specifications are used when the work pieces are of different specifications. The operation can be completed without replacing the opening handle.

In order to achieve the foregoing objective, the present invention provides an open-end wrench structure, comprising: an open handle, the end of the open handle is provided with a pivot hole and a driving portion, and the driving portion is provided with a first spine a toothed portion and a second ratchet portion; a set of a portion is provided with a slot and a corresponding pivoting hole is provided at a position of the pivoting hole of the opening handle, and the opening handle is inserted through the slot and borrowed The pivoting member is pivotally connected to the two pivoting holes, and the opening handle is pivotally connected to the sleeve portion, wherein the sleeve portion is provided with a first set space and a second set space of different specifications, so When the working piece is of different specifications, the user can complete the operation without replacing the opening handle.

Preferably, the first sleeve space and the second sleeve space of the sleeve portion are respectively provided with a first tooth receiving portion and a second receiving portion.

Preferably, the slot of the sleeve is a longitudinal design, and the opening handle is pivoted up and down in the slot of the longitudinal design.

The technical features, contents, and advantages of the present invention, as well as the advantages thereof, can be understood by the present inventors, and the present invention will be described in detail with reference to the accompanying drawings. The subject matter is only for the purpose of illustration and description. It is not intended to be a true proportion and precise configuration after the implementation of the present invention. Therefore, the scope of the attached drawings and the configuration relationship should not be construed as limiting the scope of the invention. First described.

As shown in FIG. 3 and FIG. 4 , the present invention is an open-end wrench structure, which includes an opening handle 10 , and a pivot hole 11 and a driving portion 12 are disposed at an end of the opening handle 10 . A first ratchet portion 120, a second ratchet portion 121, and a top portion 122 between the first ratchet portion 120 and the second ratchet portion 121; a set of portions 20, the sleeve The positioning portion 20 is provided with a slot 21 of the longitudinal design, and a corresponding pivot hole 22 is disposed at a position of the pivot hole 11 of the opening handle 10 for the opening handle 10 to pass through the slot 21 and The pivoting member T is pivotally connected to the two pivoting holes 11 and 22, so that the opening handle 10 is pivotally connected to the sleeve portion 20 and can be pivoted up and down in the slot 21, and the sleeve portion 20 is further The first set space 23 and the second set space 24 are provided, and the first set space 23 and the second set space 24 are different scales respectively. The first sleeve space 23 corresponds to the second ratchet portion 121, and the second sleeve space 24 corresponds to the first ratchet portion 120 and the top portion 122.

Referring to FIG. 5 and FIG. 6 , the working piece T1 of different specifications can be set in the first set space 23 or the second set space 24 of the set part 20 according to actual needs. 5, if the working piece T1 is larger in size and disposed in the second set space 24, and in FIG. 6, if the working piece T1 is small in size, it can be disposed in the first set space 23.

Furthermore, whether the working piece T1 is disposed in the first sleeve space 23 or the second sleeve space 24 of the sleeve portion 20, the first ratchet portion 120 or the second ratchet portion 121 can be used to The working piece T1 is tightly engaged. For example, in the case of FIG. 5, if the working piece T1 is larger in size, it is disposed in the second set space 24, and is respectively separated by the wall surface of the second set space 24, the first ratchet. The portion 120 and the top portion 122 are tightly engaged, and when the user pivots the opening handle 10 up and down, the working portion T1 can be rotated by the sleeve portion 20.

Please refer to FIG. 7 and FIG. 8 , which are another structural embodiment of the open-end wrench of the present invention. The first set space 23 and the second set space 24 of the sleeve 20 can be further provided with a first The receiving portion 230 and the second receiving portion 240 respectively engage the second and the ratchet portions 121 and 120 by the first and second receiving portions 230 and 240 and simultaneously engage the workpiece T1, so that the work is performed. The bite degree of the piece T1 can be greatly improved, and the user T1 is prevented from falling off when the user opens the opening handle 10.

Accordingly, the first and second sets of the space 23 and 24 of different specifications are used by the open-end wrench 10 of the present invention. Therefore, when the working piece T1 is of different specifications, the user does not need to replace the opening. The handle 10 can be operated, in other words, the open end wrench 10 of the present invention can be operated on at least one of the work pieces T1 of the above specifications.

In the above, the above embodiments and drawings are only the preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, that is, the equivalent changes and modifications made by the scope of the present invention. It should be within the scope of the patent of the present invention.
