Novel single-hand saw

Abstract

The invention discloses a novel single-hand saw. The novel single-hand saw comprises a fixed strip, wherein the right end of the fixed strip is fixedly connected with an auxiliary tightening sheath, the inner wall of the auxiliary tightening sheath is sleeved with a main frame, and the bottom end of the main frame is rotationally connected with a spherical rotating handle; a main tightening sheath is clamped to an inner cavity of an end sheath, and the lower portion of the outer surface of the main tightening sheath is rotationally connected with a rotating key; a saw blade is clamped to an inner cavity of the main tightening sheath; and the left end of the fixing strip is fixedly connected with a clamping plate, and the top end of the clamping plate is clamped to the bottom end of the saw blade. By mounting a reinforcing plate, the upper end and the lower end of the reinforcing plate are clamped on the main frame and the fixed strip respectively before use, and then the saw blade is clamped by the left end of the reinforcing plate. Thus, when the single-hand saw is used for sawing things, the saw blade can be prevented from being bent to a certain extent, and the stress of the saw blade is more concentrated. Therefore, the saw blade cannot be scrapped in advance due to the broken saw blade before being scrapped due to the fact that saw teeth are worn, and the durability of the saw blade is effectively improved.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a novel single-handed saw. Background technique [0002] The one-handed saw is one of the hardware tools often seen in construction. Because it is easy to carry, flexible, and simple in structure, it is widely used in construction, machinery production, construction and other fields. With the size of the single-handed saw, the scope of application varies. Similarly, it is most commonly used in sawing wood and steel pipes in daily life, but the single-handed saw is too thin, so when using it, if the user does not operate properly, the saw blade may be distorted and biased when the saw is unstable. If the saw blade moves, the force on the saw blade will be uneven, which will cause the saw blade to deform and even break the saw blade, resulting in unnecessary loss of the saw blade and waste. This is an undesirable phenomenon, so a method is needed to solve this problem. Conte...

[0002] One-handed saw is one of the hardware tools often seen in construction. Because it is easy to carry, strong flexibility, and simple structure, it is widely used in construction, machinery production, construction and other fields. With the different sizes of single-handed saws, the scope of application varies. Similarly, it is most commonly used in sawing wood and steel pipes in daily life, but the single-handed saw is too thin, so when using it, if the user does not operate properly, the saw blade may be distorted and biased when the saw is unstable. Shifting, the overall stress on the saw blade is uneven, which will cause the deformation of the saw blade and even the breaking of the saw blade, resulting in unnecessary loss of the saw blade and waste. This is an undesirable phenomenon, so a method is needed to solve this problem
