Description

Plastic tubing cutting device Technical Field The utility model relates to the technical field of cutting, in particular to a plastic pipe cutting device. Background The plastic pipe is a tubular plastic product which is made from synthetic resin such as polyethylene, polyvinyl chloride, polypropylene and the like as main raw materials through extrusion, injection molding, blow molding and other molding processes, in various projects, the plastic pipe is required to be cut into proper lengths and shapes according to actual installation environments and design requirements, and a plurality of cutting tools are needed for the plastic pipe, wherein a plastic pipe guillotine is a common one, and the plastic pipe guillotine has a simple integral structure and is convenient to operate, so that the plastic pipe guillotine is widely used in various projects. At present, when the existing plastic pipe guillotine is used, a worker directly places a plastic pipe to be cut into the lower part of the guillotine, then the worker drives a blade to move downwards through a rotating screw rod to complete cutting work, because the surface of the plastic pipe is usually smooth, the plastic pipe is easy to roll when the plastic pipe is subjected to external force, the cutting position of the guillotine can deviate due to pipe rolling, and the plastic pipe cannot be cut along a preset cutting line, so that uneven phenomena such as saw-tooth, wave-shaped or bevel and the like are caused in a notch, namely the sealing property and the stability of the pipe connection can be affected, and the deviation of the pipe dimension can be caused. Disclosure of utility model The utility model aims to solve the defects in the prior art and provides a plastic pipe cutting device. In order to achieve the above purpose, the present utility model adopts the following technical scheme: The utility model provides a plastic tubing cutting device, includes the plastic tubing hand hay cutter, the top of plastic tubing hand hay cutter is equipped with the connecting block, and the inside of connecting block has seted up the spread groove through seting up, the inner wall of spread groove is connected with two-way screw rod through the bearing, and two sets of movable blocks are equipped with to the outside cover of two-way screw rod, two sets of the below of movable block is equipped with the grip block respectively.
