Novel arc-shaped reciprocating saw

Abstract

The invention provides a novel arc-shaped reciprocating saw. The novel arc-shaped reciprocating saw comprises a saw body and a handle part for being connected with an electric reciprocating saw clamping device; a row of saw teeth are arranged at the cutting edge of the saw body; and the cutting edge comprises an arc-shaped curve part, and the back edge of the saw body is in an arc shape. Accordingto the technical scheme, the technical problem that an existing reciprocating saw is difficult to obtain a larger actual cutting angle is solved, and the actual cutting angle when the reciprocating saw is cutting is optimized, so that the actual cutting angle gradually increases with the arc-shaped curve, the reciprocating saw makes it easier to cut into a workpiece, the sawing depth in a singlestroke is increased, the cutting efficiency is improved, and thus efficient cutting is realized; and meanwhile, the vibration during cutting is reduced, and the comfort and safety of users are improved.

Description

technical field [0001] The invention relates to the technical field of cutting tools, in particular to a new type of reciprocating saw. Background technique [0002] Reciprocating saws are widely used in machinery, chemical industry, metallurgy, shipbuilding, food, construction and other industries. With the increasing use of reciprocating saws, the performance requirements for reciprocating saws are getting higher and higher. In order to improve the cutting efficiency of the reciprocating saw, it can be achieved by increasing the actual cutting angle of the reciprocating saw. Adjusting the handle angle of the reciprocating saw is one of the methods to increase the actual cutting angle of the reciprocating saw. However, increasing the shank angle of a reciprocating saw has the following two limiting factors. [0003] One factor that limits the angle of the reciprocating saw handle is the bezel of the electric reciprocating saw. A large reciprocating saw handle angle will sc...

Problems solved by technology

However, increasing the shank angle of a reciprocating saw has two limiting factors:

[0003] One factor that limits the angle of the reciprocating saw handle is the bezel of the electric reciprocating saw. A large reciprocating saw handle angle will scratch the bezel of the electric reciprocating saw when the reciprocating saw is cutting, resulting in damage to the bezel of the electric reciprocating saw and the reciprocating saw. wear and tear

[0004] Another factor limiting the angle of the handle of the reciprocating saw is the structure of the handle of the reciprocating saw. Since the reciprocating saw is punched from the disc saw band, as the angle of the handle of the reciprocating saw increases, the top of the handle of the reciprocating saw gets closer to the teeth. The large reciprocating saw handle angle makes the top of the reciprocating saw handle intersect with the tooth groove of the saw tooth, which will reduce the life of the punching knife when punching, and also make the reciprocating saw handle discontinuous, resulting in appearance defects
