Description

technical field [0001] The invention relates to a hand tool, in particular to a safety saw. Background technique [0002] A saw is a commonly used hand tool. Commonly used saws generally only consist of a saw blade and a handle, and the saw blade and the handle are fixedly connected, the connection angle between the saw blade and the handle cannot be changed, and the operation must be performed with both hands. In addition, when working, the entire saw blade moves back and forth, and the point of force is often far away from the handle. If it is not grasped properly, it is easy to break, which is not safe. Contents of the invention [0003] The purpose of the present invention is to provide a safety saw that can be operated with one hand and can change angles for cutting. [0004] The object of the present invention is achieved as follows: a safety saw, including a handle and a saw blade, the handle is a T-shaped structural member, and the horizontal part of the handle b...
