Abstract

The invention discloses a pre-articulated handsaw with a screw-and-nut fastening structure, comprising saw blades and a saw frame body, the front end of the saw frame body is articulated with a movable adjusting piece, both ends of the movable adjusting piece are provided with a saw blade assembling end and a tensioning end, the saw blade assembling end of the movable adjusting piece is buckled with the saw blades, the other end of the saw blade is buckled with the lower part of the back end of the saw frame body, the tensioning end of the movable adjusting piece is provided with an adjustingscrew, and the adjusting screw is matched and connected with the upper part of the back end of the saw frame body, one end of the adjusting screw is provided with a nut which can control the tightness between the saw frame body and the movable adjusting piece; the movable adjusting piece is articulated at the front end of the saw frame body, thus the structure is new, the saw blades are assembledand disassembled conveniently; a back side postpositioned pull bar tensioning structure is adopted to adjust the pulling force, thus fully guaranteeing the tension of the saw blade; a handle body with sheath can provides free handle feeling for the operator.

Description

technical field [0001] The invention relates to the technical field of hand saws, in particular to a hand saw with a front hinge and a pull rod nut fastening structure. Background technique [0002] Generally, the saw frame structure adopts a fixed frame structure, and the tension of the saw blade is mainly realized by the rotating pull rod at one end of the saw blade, or the tension of the saw blade is achieved by rotating and buckling, such as the Chinese patent patent No. ZL200520013829.1 "One A kind of hand saw" (notification number is CN2806013Y) is exactly this type of design; It is made of front saw frame, rear saw frame and connecting rod, and the inner cavity of the three forms a reserve storehouse of a spare saw blade. When the storage compartment is opened, the saw blade is sent out by the spring; the rear part of the rear saw frame is equipped with a relaxation mechanism that can be opened and closed by the rear cover to realize fast loading and unloading of the ...
