Abstract

The present invention is about an angle adjustable pliers includes a pliers body group, a jaw group and at least a locator. The pliers body group has a pair of handles. The front end of the handles form a assembling end both. Each assembling end has an assembling channel and an adjusting hole. The jaw group has a pair of jaw bodies. Each jaw body has a pivot hole which let the jaw body can be pivotally connected in the assembling channel. Beside each pivot hole are concavely set several location slots which are in annular arrange. Each location slot can face the adjusting hole when the jaw body rotates to the predetermined angle. Each locator is assembled in the adjusting hole. So when angle adjusting is required, user can rotate the jaw body to the expect direction and a engagement member of the locator would be pushed into the locator. Until one of the location slots faces the adjusting hole again, the engagement member will snap into the location slot again to locate the jaw in the required angle.

Description

Adjustable angle clamp

The present invention relates to an adjustable angle pliers, which is a hand tool suitable for holding or fixing parts for facilitating the disassembly or assembly of parts.

Conventional clamps are generally used for clamping or fixing parts to facilitate the disassembly or assembly of parts. However, most of the clamps on the market are fixed between the tool head and the handle, but the assembly positions of the parts are different. The disassembly or assembly of some parts requires tilting the tool head of the clamp to a certain angle for easy operation. However, if the tool head is tilted to a specific angle, it will affect the posture of the hand holding the handle, which will further affect the application. Force, so it is quite inconvenient in operation.

In view of the above-mentioned shortcomings, the inventor believes that it is necessary to make corrections. Based on years of experience in related technologies and product design and manufacturing, the inventor has been adhering to the excellent design concept and researching and creating the above disadvantages. After continuous efforts, The adjustable angle clamp of the present invention is introduced to correct the product structure to enhance the superior performance of the product.

The main object of the present invention is to provide a tool holder (or a working end) that can adjust the angle changing direction of the clamp to improve the disadvantages of the inconvenience that the conventional clamp can not change the operating angle of the tool head (or the working end).

For the purpose of the foregoing disclosure, the adjustable angle angle clamp of the present invention comprises a forceps set, a clamp head set and at least one positioner, the forceps set having a set of pivotable grips, the two grips The front end of the shank is formed with an assembly end, and an adjacent side of each of the assembly ends defines an assembly slot, and an adjustment hole is respectively defined on an outer side of each of the assembly ends, and the tong head group has a set of symmetrical numbers. a clamping hole is defined in each of the clamping head bodies, and each of the pivoting holes is configured to pivot each of the clamping head bodies in each of the assembly slots, and each of the pivoting holes is located beside each of the adjusting holes a predetermined distance, and each of the head body is rotated according to the center of the pivot hole, and each of the pivot holes is surrounded by a plurality of positioning grooves, and each of the positioning grooves can be rotated with each of the head bodies. The adjusting body can be respectively opposite to each of the adjusting holes, and each of the clamping head bodies has a working end, and the positioning device is used for assembling in each of the adjusting holes, the positioning device has an adjusting body, and the adjusting body is concave at one end. There is a recessed hole which is assembled sequentially from the inside to the outside Positioning a resilient member and the card member, said positioning member for positioning to the latching groove.

By the way, when the positioning slots are respectively opposite to the adjusting holes, the positioning card can be engaged in the positioning slot, so that the angle of each working end is fixed, and if the angle needs to be adjusted, only the head body needs to be oriented. When the angle direction is to be changed, the positioning card can be pressed back into the recessed hole, and the positioning card can be locked into the positioning when the next positioning slot is again opposite to the adjusting hole. In the slot, each working end can be fixed at an angle to be used to achieve the purpose of adjusting the angle.

The angle clamp can be adjusted. Further, the adjustment hole is threaded, and the periphery of the adjustment body can be matched with the adjustment hole to provide a thread. Therefore, the positioning card can be adjusted through the rotation of the thread. The tightness of the squeeze between the adjustment holes.

The present invention relates to an adjustable angle clamp, [see the first figure] which includes:

a clamp body (1) having a set of grips (11) that can be pivotally connected to each other, so that the two grips (11) can pivot according to the pivot point, since this part belongs to the technology of the conventional tool Therefore, the rear end of each of the grips (11) is formed with an assembly end (12), and an adjacent assembly side (12) has an assembly groove (13) on each side of the assembly end (12). An adjustment hole (14) is respectively defined on an outer side of each of the assembly ends (12), and in this embodiment, the adjustment hole (14) is threaded;

a clamping head set (2) having a set of symmetrical head bodies (21), each of which has a pivot hole (22), each of the pivot holes (22) being used for each The clamping head body (21) is pivotally disposed in each of the assembly slots (13), and each of the pivoting holes (22) is located at a predetermined distance beside each of the adjusting holes (14), and each of the clamping head bodies (21) In order to make each of the jaw body (21) easier to rotate, in this embodiment, each of the jaw body (21) may be provided with a plurality of sections (211). And each of the pivot holes (22) is surrounded by a plurality of positioning grooves (23), and the positioning grooves (23) are respectively adjustable with the rotation of each of the jaw bodies (21) The working holes (14) are opposite to each other, and each of the working heads (21) has a working end (24). In this embodiment, the working end (24) is hook-shaped;

At least one positioner (3), [see second figure] is used for assembly in each of the adjustment holes (14), the positioner (3) has an adjustment body (31), the periphery of the adjustment body (31) The adjusting hole (11) is provided with a thread (311), and one end of the adjusting body (31) is recessed inwardly with a recessed hole (312), and the recessed hole (312) is sequentially assembled with an elastic member from the inside to the outside ( 32) and a positioning clip (33), in this embodiment, the positioning clip (33) is spherical.

The angle clamp can be adjusted according to the present invention, [see second to fourth figures], when each of the positioners (3) is assembled in each of the adjustment holes (14), and each of the positioning grooves (23) is The positioning clips (33) can be engaged in the positioning slots (23) as the respective clamping head bodies (21) are respectively rotatable relative to the adjusting holes (14), so that the working ends (24) The angle is fixed. If the angle needs to be adjusted, only the head body (21) needs to be pulled toward the angle to be changed, and the spherical positioning card (33) can be squeezed to compress the elastic member. (32) returning to the recessed hole (312), and when the next positioning slot (23) is opposite to the adjusting hole (14), the positioning clip (33) can be re-engaged into the positioning slot (23). Inside, so that each working end (24) can be fixed at the angle to be used.

The angle clamp can be adjusted according to the present invention. [Please refer to the second figure] In this embodiment, the periphery of the adjustment body (31) is provided with a thread (311) and is assembled with the adjustment hole (14), so The rotation of the thread can also adjust the tightness between the positioning clip (33) and the adjusting hole (14).
