Embodiment Construction

[0031] Please refer to Figure 1 to Figure 14 , the dual-purpose electric hand saw in the figure mainly includes a fixed assembly 1, an external rotation assembly 2, and a saw head assembly 3; the saw head assembly 3 is fixed inside the external rotation assembly 2. The fixed component 1 is mainly used to form the grip part, which fixes, supports and positions other components; the external rotating component 2 is mainly used to drive the internal rotating component 4 to rotate, and then drives the saw head component 3 to rotate; the saw head component 3 mainly includes Saw head 31.

[0032] The fixing assembly 1 includes two split-type fixing shells 11 that are assembled by screws or buckles. The above two fixing shells 11 are combined to form an annular first groove end 111 and a first raised end 112 that are dislocated up and down; The outer rotation assembly 2 includes two split outer rotation housings 21 that are assembled by screws or buckles. The outer rotation housing...

Abstract

The invention discloses a dual-purpose electric hand saw comprising a fixed assembly, an outer rotary assembly and a saw head assembly. The saw head assembly is fixed in the outer rotary assembly. Thefixed assembly comprises a plurality of split type fixed shells. The fixed shells are spliced to form first annular groove ends and first annular convex ends which are staggered up and down. The outer rotary assembly comprises a plurality of split type outer rotary shells. The outer rotary shells are spliced to form second annular convex ends and second annular groove ends which are staggered upand down. The second convex ends and the first groove ends are matched. The first convex ends and the second groove ends are matched. Through the dual-purpose electric hand saw, the technical problemsof how to innovate a present saw head structure so as to improve comprehensive performance of a scroll saw can be solved.

Description

technical field [0001] The invention relates to a hardware tool, in particular to a jigsaw, which can be used for plug-in or wireless lithium battery rechargeable jigsaws, and can be used for reciprocating saws. Background technique [0002] Curve saw belongs to a kind of hardware tool, which is widely used in cutting work, such as woodworking cutting boards. Current jig saws often cannot rotate the saw head to flexibly change the cutting direction, or have the ability to rotate the saw head around a fulcrum. Rotation is achieved on a longitudinal surface through the hinged inversion structure from top to bottom, from bottom to top, and its saw blade keeps the same direction and cannot be turned over. The orientation before adjustment and after adjustment is in the same direction instead of the opposite direction. , but also artificially remove the saw blade, and then reinstall the saw blade, which greatly reduces the practicability of the product. Contents of the inventio...
