Abstract

The invention discloses a retractable hand saw. The retractable hand saw comprises a supporting mechanism, a hanging mechanism, an adjusting mechanism, a handle mechanism, a steel saw blade and a butterfly nut. The hanging mechanism is rotationally connected to the top end of one side of the supporting mechanism. The handle mechanism is rotationally connected to the end, away from the hanging mechanism, of the supporting mechanism. The adjusting mechanism is rotationally connected to the bottom face of the side, close to the handle mechanism, of the supporting mechanism. The steel saw blade isinteractively clamped between the hanging mechanism and the adjusting mechanism. The butterfly nut is in threaded connection between the adjusting mechanism and the handle mechanism. The supporting mechanism is used for providing storage and support. The hanging mechanism and the adjusting mechanism are used for fixing the steel saw blade. The handle mechanism is used for fixing the adjusting mechanism. The retractable hand saw can be contracted into the structural shape of the supporting mechanism after being used, and is convenient to place and carry, and the steel saw blade cannot damage bags or hurt users.

Description

technical field [0001] The invention relates to the technical field of manual saws, in particular to a retractable manual saw. Background technique [0002] The hand saw was invented by Lu Ban, the originator of woodworking. The oldest woodworking hand saw usually has a Japanese shape. By adjusting the tightness of the screws on the opposite side of the saw blade, the saw blade can be stretched straight for easy operation. After continuous improvement, it has become smaller and more compact. There are more varieties. Hacksaws, straight saws and other varieties have appeared. [0003] However, the existing manual saws have the following disadvantages in use, such as: [0004] 1. The traditional manual saw is very inconvenient to carry because of its large size; [0005] 2. The hacksaw blade of the traditional manual saw is exposed outside, which is easy to cause harm to the user during use, and it is easy to damage the bag even if it is placed inside the tool bag when it i...
