Description

Oscillating head ratchet wrench

technical field

The utility model relates to a ratchet wrench, in particular to a shaking head type ratchet wrench which is convenient to use.

Background technique

Existing ratchet wrenches usually have a handle body and a ratchet head fixed on the handle body. Since the ratchet head cannot rotate relative to the handle body, the relative angle between the two can be changed. Therefore, when When the user uses the ratchet wrench to lock a screw on a working surface, the space between the handle body and the working surface is often too small for the user's hand to hold the handle at the end. The problem of the body makes it difficult for the user to apply force, so that the screw cannot be locked on the working surface. At this time, to improve this problem, the user often needs to use another sleeve to connect the ratchet wrench and the ratchet wrench. Screws are even more inconvenient.

Utility model content

The purpose of the utility model is to provide an oscillating head type ratchet wrench which can adjust the relative angle between the ratchet head and the handle body and is convenient to use.

The utility model oscillating head type ratchet wrench comprises a ratchet head, a handle body, and a positioning device. The ratchet head has a connecting end. The handle has a first end facing the connecting end, and a second end opposite to the first end along an axial direction. The positioning device includes a connecting block arranged on one of the connecting end and the first end, two lugs arranged on the other of the connecting end and the first end, a A wave spring, and a rotating shaft, the connecting block has two outer surfaces, and a perforation passing through the outer surfaces in a transverse direction perpendicular to the axial direction, and the lugs are arranged at intervals along the transverse direction, so An accommodating space for the connection block to be placed is defined between the ear pieces, and the ear pieces respectively have an inner surface facing the outer surface, and an opening arranged along the transverse direction and passing through the inner surface , the wave spring has a central hole, the wave spring is installed between one of the outer sides and one of the inner sides, and forces the other side of the outer side and the inner side The other side abuts, and the rotating shaft passes through the opening of the lug along the transverse direction, the through hole of the connecting block and the central hole of the wave spring.

Thereby, the utility model can not only adjust the relative angle between the ratchet head and the handle body, but also position the ratchet head at a predetermined angle position, so that it is convenient for the user to hold the handle body and exert force.

Detailed ways

The shaking head type ratchet wrench of the present utility model is described in detail below through the best embodiment and accompanying drawings:

The aforementioned and other technical content, features and effects of the present utility model will be clearly understood in the following detailed description of a preferred embodiment with reference to the drawings.

Referring to Figures 1, 2 and 3, it is a preferred embodiment of the oscillating ratchet wrench of the present invention, which includes: a ratchet head 10, a handle body 20, and a positioning device 30.

The ratchet head 10 has a base 11, a ratchet ring 12 that can be installed in the base 11, a clasp 13 installed between the base 11 and the ratchet ring 12, and a ring 13 formed on the base. The connection end 14 on the body 11. In this embodiment, the ratchet ring 12 is a one-way operation ratchet ring, and a one-way stop member (not shown) matching the ratchet ring 12 is also provided inside the base body 11, however, this It is not the focus of the request in this case, so it will not be explained in detail here.

The handle body 20 has a first end portion 21 facing the connecting end portion 14 , and a second end portion 22 opposite to the first end portion 21 along an axis X. The second end 22 of the handle body 20 has an opening slot 221 , and in this embodiment, the opening slot 221 can also be used for locking screws and other work pieces.

The positioning device 30 includes a connecting block 31 arranged on the connecting end 14, two lugs 32 arranged at intervals on the first end 21 along a transverse direction Y perpendicular to the axis X, and a Wave spring 33, and a rotating shaft 34.

The connecting block 31 has two outer surfaces 311 , a through hole 312 passing through the outer surfaces 311 along the transverse direction Y, and a shallow groove 313 disposed on one of the outer surfaces 311 and communicating with the through hole 312 .

An accommodating space 35 for the connection block 31 can be defined between the lugs 32, and the lugs 32 respectively have an inner side 321 facing the outer side 311, and an inner side 321 along the transverse direction. The direction Y is set and passes through the opening 322 of the inner surface 321 .

The wave spring 33 (wavy spring) has two first abutting portions 331 arranged at intervals along the circumferential direction, two second abutting portions 332 arranged between the first abutting portions 331, and a central hole 333. In this embodiment, the wave spring 33 is installed between the shallow groove 313 and one of the inner surfaces 321, the first abutting portion 331 is in contact with the shallow groove 313, the first The second abutting portion 332 abuts against the inner side 321 , and the elastic restoring force of the wave spring 33 can force the outer side 311 opposite to the shallow groove 313 to abut against the other inner side 321 .

The rotating shaft 35 passes through the opening 322 of the lug 32 , the through hole 312 of the connecting block 31 , the shallow groove 313 , and the center hole 333 of the wave spring 33 along the transverse direction Y. The rotating shaft 34 has two pivotal ends 341, and a middle portion 342 connected between the pivotal ends 341. In this embodiment, the pivotal ends 341 are connected to the lugs 32 respectively. The opening 322 of the connecting block 31 is pivotally connected, and the middle part 342 has a plurality of protruding clamping strips 343 which are clamped in the through hole 312 of the connecting block 31 .

Thereby, as shown in FIGS. 2 and 3 , since the elastic restoring force of the wave spring 33 can force the outer surface 311 opposite to the shallow groove 313 to abut against the inner surface 321 to generate a certain degree of tightness, therefore , when the ratchet head 10 swings within an angle range of 180 degrees relative to the handle body 20 , no matter to which angle the ratchet head 10 swings, the ratchet head 10 can be positioned at a predetermined angular position.

As shown in Figure 4, when the user wants to lock a screw 100 on a working surface 200, the user can make an angle between the ratchet head 10 and the handle body 20, so that the handle body 20 can be tilted away from the working surface 200, so that a large enough space can be separated between the handle body 20 and the working surface 200, and the user's hand can easily hold the handle body 20, so , the user can effectively apply force to lock the screw 100 on the working surface 200, on the contrary, when the user wants to remove the screw 100 from the working surface 200, the user's hand will also The handle body 20 can be held conveniently, and the screw 100 can be reversed by applying force effectively.

Through the above description, the advantages of the present utility model can be summarized as follows:

Since the elastic restoring force of the wave spring 33 can force the outer surface 311 opposite to the shallow groove 313 to abut against the inner surface 321 to generate a certain degree of tightness, therefore, when the ratchet head 10 is relative to the handle body When the ratchet head 10 is swinging, the ratchet head 10 can be positioned at a predetermined angular position, so that the user can adjust the angle between the ratchet head 10 and the handle body 20 as needed, and then in various operating situations , can easily hold the handle body 20 to apply force.

To sum up the above, the oscillating ratchet wrench of the utility model can not only adjust the relative angle between the ratchet head and the handle body, but also position the ratchet head at a predetermined angle position, so that the user can hold the handle body and apply force. So really can reach the purpose of the utility model.
