Reciprocating saw with adjustable teeth

Abstract

The invention discloses a reciprocal saw with adjustable sawtooth comprising a saw body and a saw blade; the saw blade comprises a first tooth plate, a second tooth plate and multiple saw teeth; one ends of the saw teeth are installed between the first tooth plate and the second tooth plate; the saw teeth are fixed by the first tooth plate and the second tooth plate through a clamping bolt; one ends, away from the saw body, of the first tooth plate and the second tooth plate are provided with a coiler; the coiler is provided with three indication wires and a pointer; one end, close to the saw body, of the first tooth plate is provided with a limiting block; the saw teeth are connected through an elastic rope; one end of the elastic rope is wound in the coiler; a first saw teeth on the other end of the elastic rope is provided with a spacing hole which is matched with the limiting block. When the reciprocal saw with adjustable sawtooth is set aside, the elastic rope and the saw teeth are collected in the coiler which can effectively prevent accidental injury to people; the density can be adjusted according to the specific circumstances of the sawtooth use so that the reciprocal saw of the invention is very convenient to use.

Description

technical field [0001] The invention belongs to the field of electric tools, and in particular relates to a reciprocating saw with adjustable saw teeth. Background technique [0002] A reciprocating saw cuts material with a serrated blade that reciprocates back and forth. Reciprocating saws are usually equipped with multiple saw blades. The difference between these saw blades is that the saw teeth on them are different in density. The thin saw teeth have high cutting efficiency, but the cut surface is rough, and the dense saw teeth cut has low efficiency but the cut surface is flat. Therefore, when cutting, the operator often selects the most suitable saw blade according to the situation, but it is inconvenient to carry these saw blades at any time. And the exposed sawtooth may cause accidental injury to others and oneself, which is very unsafe. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the invention provides a reciprocating saw capa...
