Abstract

The invention discloses a hand saw with a saw blade convenient to dismount and mount. The problem that a saw blade is not convenient to dismount and mount due to the fact that the saw blade is fixed in a nut tightening mode is solved. The hand saw with the saw blade convenient to dismount and mount is characterized in that an inner cavity is formed in the bottom of a saw frame, and an elastic mechanism is arranged in the inner cavity and hinged to a rear end fixing part; a control mechanism is arranged at the bottom of the saw frame and connected with the elastic mechanism; and the control mechanism is used for controlling the tightness of the elastic mechanism. When the saw blade of the hand saw is dismounted and mounted, only the control mechanism at the bottom of the saw frame needs to be adjusted, and then the control mechanism drives the elastic mechanism to adjust the distance between the rear end fixing part and the front end part of the fixed saw blade, so that the saw blade is easy and convenient to dismount and mount, and the tensioning force of the saw blade can be ensured after the saw blade is mounted.

Description

Technical field [0001] The invention relates to the field of manual saws, in particular to a manual saw which is convenient for disassembly and assembly of a saw blade. Background technique [0002] Hand saws are popular with people because of their lightness, flexibility, quickness and practicality. They are widely used for cutting various tools. However, general hand saws use nuts to tighten the saw blade. The tightening force varies with people, so the saw blade Sometimes the tension force is insufficient, causing the saw blade to break, and sometimes the nut is screwed too tightly, which makes it inconvenient to remove the saw blade. Summary of the invention [0003] In order to solve the problem of inconvenient disassembly and assembly of the saw blade caused by fixing the saw blade by tightening a nut, the present invention provides a hand saw with convenient assembly and disassembly of the saw blade. [0004] The technical scheme adopted by the present invention is as follow...
