Problems solved by technology

However, according to the basic principle of stamping parts, it can be known that the saw blade will rebound when it is bent. The two saw blades cannot maintain a good relative position, there may be a large gap, or they may interfere with each other, and even cause serious friction.

Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] see figure 1 and figure 2 , an electric reciprocating saw, including a casing 1, a first reciprocating rod 21 and a second reciprocating rod 22 arranged in parallel in the casing 1, detachably connected to the first reciprocating rod 21 by a first clamping mechanism 31 The first saw blade 41 that can move reciprocatingly through the first reciprocating rod 21 is detachably connected to the second reciprocating rod 22 through the second clamping mechanism 31, so that the second reciprocating rod 22 can drive the reciprocating first saw blade 41. Two saw blades 42.

[0026] see Figure 3-Figure 6 , the first saw blade 41 includes a first cutting body 411 and a first mounting portion 412 that are both planar, and the second saw blade 42 also includes a second cutting body 421 and a second mounting portion 422 that are both planar. The...

Abstract

The invention discloses a paired saw blade structure of a reciprocating saw. The paired saw blade structure comprises a first saw blade and a second saw blade which are arranged in parallel. The first saw blade comprises a first cutting body and a first mounting portion; the second saw blade comprises a second cutting body and a second mounting portion. A guide hole extending along a cutting direction is formed in the first cutting body, a rivet which penetrates the guide hole further penetrates the second cutting body so as to tighten the first saw blade and the second saw blade, the first cutting body and the first mounting portion are both planes and in dislocated welding, and the second cutting body and the second mounting portion are both planes and are also in dislocated welding. Besides, a boss capable of extending into the guide hole is punched and formed on the second cutting body, and the width of the boss is matched with that of the guide hole. The mounting portions and the cutting bodies of the saw blades are linear components, so that parallelism between the two saw blades is guaranteed easily. Since the boss is hard and has a large contact area with the guide hole, high-speed motions of the saw blades can be kept for a long time.

Description

technical field [0001] The invention relates to a reciprocating saw, in particular to a paired saw blade structure of the reciprocating saw. Background technique [0002] Electric reciprocating saw is a relatively commonly used tool, which is widely used in industries such as automobiles, communication, wood molds, decoration, leather, etc. Through the up and down reciprocating motion of the saw blade, it can perform linear or horizontal cutting on wood, metal, plastic, rubber and other workpieces. Curve cutting, adjust the left and right angles of the bottom plate to perform bevel cutting. [0003] Commonly used reciprocating saws only use a single saw blade for cutting, but at present there have been reciprocating saws with double saw blades, which use the relative reciprocating motion of the two saw blades to cut the workpiece. The reciprocating saw with double saw blades uses the relative movement of the two saw blades to improve the cutting ability and efficiency of th...
