Description

clamp

The present invention is related to pliers.

Generally speaking, in order to tightly sleeve an inner tube and an outer tube to avoid leakage, an elastic band is used to sleeve the outer tube. The two end pieces are clamped together to expand the radial size of the ring, and the assembly can be disassembled.

However, during the operation of the conventional pliers, the user and the pliers need to have one side of the two-end piece facing the collar, so that the two-end piece can be smoothly clamped and the two-end piece can be prevented from being clamped. In the process of disengaging from the clamp, when the working space is narrow and the two-end piece is located on the side of the collar opposite to the user, the two-end piece cannot be smoothly clamped, and there is a disadvantage that needs to be improved.

Therefore, it is necessary to provide a novel and progressive forceps to solve the above problems.

The main purpose of the present invention is to provide a pliers, which can clamp the two end pieces of the tie ring in various directions and positions relative to the tie ring, so as to smoothly carry out the process of disassembling and assembling the tie ring.

In order to achieve the above object, the present invention provides a forceps, comprising: two forceps bodies. Each clamp body includes a clamp portion, a pivot portion and a handle portion, the pivot portion of each clamp body is connected between the clamp portion and the handle portion, and the two pivot portions are pivotally connected along a rotational axis. , the clip portion includes a clip jaw and a first bending section, the first bending section is located between the pivoting section and the clip jaw, and one side of the two first bending sections facing each other forms a concave Each of the clamping jaws is provided with at least one first clamping groove and at least one second clamping groove, and each of the first clamping groove and each of the second clamping grooves extend laterally to each other.

The following examples only illustrate possible implementations of the present invention, but are not intended to limit the scope of protection of the present invention, and are described together first.

Please refer to FIGS. 1 to 6 , which show an embodiment of the present invention. The forceps of the present invention includes two forceps bodies 1 .

Each forceps body 1 includes a clip portion 2, a pivot portion 3 and a handle portion 4. The pivot portion 3 of each forceps body 1 is connected between the clip portion 2 and the handle portion 4. The two pivot portions 3 are pivotally connected along a rotational axis, the clip portion 2 includes a clip jaw 21 and a first bending segment 22, the first bending segment 22 is located between the pivot portion 3 and the clip jaw 21, the A notch 23 is formed on the opposite side of the two first bending sections 22 . Each of the clamping jaws 21 is provided with at least one first locking groove 211 and at least one second locking groove 212 . Each of the second locking grooves 212 extends laterally to each other. In this embodiment, the pliers are used for a pipe body 91 . The pipe body 91 is a three-way pipe and is provided with a plurality of bundle rings 92 , and each of the bundle rings 92 is provided with two end pieces 921 .

In actual use, the two clamping jaws 21 are respectively clamped against the two end pieces 921 to make the two end pieces 921 close to each other, so that the radial dimension of the collar 92 can be changed for disassembly. There are at least one first locking groove 211 and at least one second locking groove 212, so the end of each end piece 921 can be locked against one of the first locking grooves 211 or one of the second locking grooves 212 (as shown in Fig. 3 and FIG. 5 ) to firmly hold the two-end piece 921 to prevent the two-end piece 921 from being separated from the two clamping jaws 21 . In this embodiment, each of the clamping jaws 21 is provided with a plurality of first clamping grooves 211 and a plurality of second locking grooves 212, so the end piece 921 can be arbitrarily locked against one of the first locking grooves 211 or one of the second locking grooves 212, which is more convenient to use.

In addition, as shown in FIG. 5 , when the working environment is narrow and the two end pieces 921 are located on the side of the girdle 92 opposite to the user, since the two first bending sections 22 face one side to form the notches 23, so the two clamp bodies 1 can cross the tube body 91 by the two first bending sections 22, so that the tube body 91 can pass between the two notches 23, and also can effectively clamp The two end pieces 921 of the tie ring 92 are set for disassembly and assembly.

Specifically, each of the clamping jaws 21 is in the shape of a rectangular plate, the first clamping grooves 211 extend parallel to the long sides of the clamping jaws 21 , and the second clamping grooves 212 extend parallel to the short sides of the clamping jaws 21 , so that the The two clamp bodies 1 can be clamped against the two end pieces 921 in the direction of the straight or transverse direction of the pipe body 91 . In this embodiment, a plurality of protrusions 213 are protruded from one side of each of the clamping jaws 21 facing each other, and the protrusions 213 of each of the clamping jaws 21 are arranged in a matrix to form a plurality of the first locking grooves 211 and a plurality of The second card groove 212 .

Further, one of the pivot parts 3 is provided with a pivot post 31 , and the other pivot part 3 is provided with a pivot hole 32 , the pivot post 31 is rotatably inserted in the pivot hole 32 , so that the two clamps The body 1 can be pivoted relative to each other. Preferably, a concave section 34 is provided on one side of the opposite surface of each of the pivoting parts 3 , and the two concave sections 34 can avoid increasing the thickness of the two pivoting parts 3 when they are superimposed.

It is worth mentioning that the pivot hole 32 is a wave-shaped hole, the pivot column 31 is a rectangular column, and the pivot column 31 includes two opposite arcuate sides 311 and two opposite straight side sides 312. The two straight sides The relative distance between the sides 312 is smaller than the relative distance between the two arc sides 311. When the two clamp bodies 1 swing to an angle so that the two straight sides 312 are parallel to the wave-shaped hole, the pivot column 31 can follow the wave-shaped hole. The holes slide to adjust the relative positions of the two clamp bodies 1 , so as to be adjusted according to the specifications of different tube bodies 91 or different collars 92 .

Wherein, the two pivot parts 3 are overlapped along the rotational axis so that the two clamp bodies 1 are cross-pivoted, so that when the two handle parts 4 are closed together, the two clamping jaws 21 are also closed together, which can be easier to carry out. operate.

Preferably, each of the first bending sections 22 is arc-shaped, which can avoid interference with the tube body 91. When the two jaws 1 are pivoted to make the two jaws 21 close together, the two concave The opening 23 forms a through hole 5, and the radial dimension of the through hole 5 is not less than four centimeters.

In this embodiment, each pivot portion 3 includes a second bending section 33 , the first bending section 22 and the second bending section 33 of each clamp body 1 extend in an S shape, and each clamp body 1 extends in an S shape. The clip portion 2 , the pivot portion 3 and the handle portion 4 of the body 1 are integrally connected to have better structural strength.
