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 group, a clamp head set and a plurality of positioners, the forceps set having a set of pivotable grips, and the handles The front end of each of the assembly ends has an assembly slot, and an adjustment hole is respectively defined on an outer side of each of the assembly ends, and the clamp head group has a set of symmetrical numbers. Each of the jaw body has a pivot hole, and each of the pivot holes is used for pivoting each of the jaw bodies in each of the assembly slots, and each of the pivot holes is located beside each of the adjustment holes a predetermined distance, and each of the jaw 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 slots can be rotated with each of the jaw bodies The aligner body has a working end, and the locator is configured to be assembled in each of the adjusting holes, the locator has an adjusting body, and the adjusting body has one end inward. A recessed hole is formed in the recess, and the recessed hole is sequentially assembled with an elastic member and a positioning clip from the inner side to the outer side, and the positioning clip is used for locking in the positioning 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 second figure is a partial cross-sectional view of the forceps of the present invention.

The third figure is a partial plan view of the forceps of the present invention.

The fourth figure is a partial plan view showing the adjustment angle of the clamp of the present invention.

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, no further description is made. Then, the front ends of the two grips (11) are formed with an assembly end (12), and an assembly groove is formed between adjacent side edges of each of the assembly ends (12). An adjustment hole (14) is respectively disposed on an outer side of each of the assembly ends (12). In this embodiment, the adjustment hole (14) is threaded, and each of the assembly slots (13) is respectively Forming a limiting portion (15); a clamping head group (2) having a pair of symmetrical head bodies (21), each of the clamping head bodies (21) having a pivot hole (22), each of the pivots The hole (22) is used for pivoting each of the jaw body (21) in each of the assembly slots (13), and each of the pivot holes (22) is located at a predetermined distance beside each of the adjustment holes (14). And each of the jaw body (21) is rotated according to the center of the pivot hole (22), so that the jaw body (21) is more easily rotated, in this embodiment, each of the jaw body (21) A plurality of cut surfaces (211) may be disposed on the periphery, and each of the pivot holes (22) is surrounded A plurality of positioning grooves (23) are disposed around the recess, and each of the positioning grooves (23) can be respectively opposed to the adjusting hole (14) according to rotation of each of the clamping head bodies (21), and each of the clamping heads The main body (21) has a working end (24) respectively. In this embodiment, the working end (24) is hook-shaped; the plurality of positioners (3), [see the second figure] are used for assembly. In each of the adjustment holes (14), the positioner (3) has an adjustment body (31), and the periphery of the adjustment body (31) can be matched with the adjustment hole (14) and provided with a thread (311), the adjustment body (31) one end is recessed inwardly with a recessed hole (312), and the recessed hole (312) is sequentially assembled with an elastic member (32) and a positioning clip (33) from the inside to the outside, in this embodiment, the positioning The card member (33) is spherical.
