Detailed ways

The utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. Apparently, the described embodiments are only a part of the embodiments of the utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Fig. 1-5, the utility model provides a kind of technical solution: the upper left part of the pipe wrench body 1 has fixed jaws 101, the upper end of the pipe wrench body 1 has an upper groove 102, and the upper end is concave The movable pliers body 2 that can slide in this upper end groove is installed in the groove 102, and the upper and lower ends of the movable pliers body 2 have pincer teeth 201, and the movable pliers body rack 202 is arranged on the front side of the movable pliers body 2. The left end of the movable pliers body 2 is provided with a threaded blind hole 203. The threaded blind hole is threadedly matched with the sliding handle 4. The front side of the pipe wrench body 1 has a front side groove 103, and a card is installed in the front side groove 103. Block 3, the inside of the block 3 is provided with a block rack 301, the block rack 301 is engaged with the movable pliers rack 202 on the front side of the movable pliers body, and the block 3 is provided with a first pass hole 302, the lower end of the clamp block 3 is provided with a second through hole 303, the left end of the pipe wrench body 1 has a left end groove 105, and the sliding handle 4 passes through the left end groove 105 at the left end of the pipe wrench body 1 and The threaded blind hole 203 at the left end of the movable pliers body 2 is threadedly matched, and the pipe wrench pliers body 1 is provided with a third through hole 106, which is installed in the second through hole 303 at the lower end of the clamp block 3 . There is a rotating shaft 5, and the left side of the pipe wrench body 1 is provided with a fourth through hole 107, and the fourth through hole 107 is connected with the first through hole 302 provided with the block 3 through a spring 6. The lower end of the pliers body 1 has a lower end groove 104 .

The working principle of the utility model is: when using a pipe wrench, the left end of the clamp block 3 connected to the rotating shaft 5 is moved to open the clamp block 3, so that the movable clamp body rack 202 on the front side of the movable clamp body 2 is aligned with the inside of the clamp block 3 The block rack 301 is out of engagement, so that the movable pliers can slide in the upper groove 102, because the sliding handle 4 passes through the left groove 105 at the left end of the pipe wrench pliers 1 and the threaded blind hole at the left end of the movable pliers 2 Thread fit, thereby slide movable pliers body 2 by dragging sliding handle 4, adjust the distance between jaws 201 of movable jaws 2 and fixed jaws 101 according to the size of workpiece during work.
