1. Pipe wrench

The pipe wrench refers to a tool used to clamp and rotate steel pipes, and the connection between pipes is completed by clamping and twisting the pipes. When using, pay attention to the choice of specifications; the opening of the head of the pliers is equal to the diameter of the workpiece; use force after the pliers squeeze the workpiece tightly to avoid slipping; use force within the strength of the pipe wrench, and keep the jaws and adjusting ring clean. Before use, check whether the locking pin is strong, whether there are any cracks on the head and handle of the pliers, if there are any, they should not be used.

2. Clamp

The clamping clamp is mainly composed of base, post, rotating arm and bolts. It is widely used in the boiler pipeline installation project, and it is used to make threaded buckles for pressing pipelines. Pliers are common tools used to clamp metal pipes for bending and sawing. With the rotary pen and screw rod, you can repair bolts, press the pad, reverse the camera, repair inner and outer tires, etc., and do some auxiliary maintenance work. When the clamp clamps a large pipe, a pipe wrench should be added at the back to prevent the pipe from slipping off and damaging the pipe and jaws; when clamping the pipe, it should not be too strong, but should be tightened gradually so that the pipe is not clamped flat or the teeth of the pliers do not corrode the pipe too much. on the screw part.

The keel clamp is used to install the partition wall in the decoration project. During the construction of the partition wall, the keel clamp is used to fix the sky keel, earth keel and vertical keel, which can replace the traditional process and complete it in one step. Its advantages are energy and material saving, easy operation and smooth working surface. In use, it is also necessary to hold the body of the pliers perpendicular to a stationary surface. The position of the punch cut should be set at a 45° angle between the vertical keel and the bottom surface of the horizontal keel. to achieve a perfect and strong bite of the horizontal keel and vertical keel.

5. Pliers

Pliers, also known as a machine vice, are a versatile tool suitable for holding small workpieces. It is a suitable accessory for milling and drilling machines.
