Plastic pipe scissors

Technical Field

The utility model relates to a shearing tool field especially relates to a mould tub scissors.

Background

In order to adapt to different installation environments, the plastic pipe is often required to be cut and connected according to the actual size during installation, and plastic pipe shearing is a common installation step in pipeline installation, so that the convenient and easy-to-use plastic pipe scissors are very practical. In the existing product, the plastic pipe is cut by hands of operators, and even though part of the plastic pipe provides electric power, the plastic pipe still cannot completely save manual hand power and completely cut by electric power. When cutting individual plastic pipes, operators often experience excessive force such as hand soreness.

For example, in the patent of chinese utility model with publication number "CN 202498559U," entitled "plastic pipe scissors", it provides a plastic pipe scissors with a pushing aid, and its main power source is still provided by the handle of the lower end pushed by the hand, which can not really solve the problem of labor saving for the plastic pipe installer.
