Reciprocating cutting tool

Abstract

The invention provides a reciprocating cutting tool, which is used for cutting workpieces and comprises a casing, a motor, a reciprocating lever and a handle, wherein the casing comprises a motor casing and a transmission casing, the motor is contained in the motor casing and provided with a motor axis, the reciprocating lever is contained in the transmission casing and driven to reciprocate by the motor, and the handle is connected with the casing. The transmission casing is capable of rotating around the motor axis relative to the handle. The motor of the reciprocating cutting tool is arranged outside the handle, so that the handle of the reciprocating cutting tool is small in size, and holding comfortableness is improved. Besides, as the casing rotates around the motor axis relative to the handle, the reciprocating cutting tool has a first operating state and a second operating state, is small in size and meets the requirement on miniaturization.

Description

technical field [0001] The invention relates to a reciprocating cutting tool, in particular to a hand-held reciprocating cutting tool. Background technique [0002] Both the reciprocating saw and the jigsaw are one of the reciprocating cutting tools, and their working principles are basically the same. They are both driven by a motor to drive the reduction gear, which drives the reciprocating rod to reciprocate, so that the saw blade connected to the free end of the reciprocating rod can cut the workpiece Perform reciprocating cutting operations. The only difference is that the jigsaw cuts against the surface of the workpiece through a bottom plate, the gravity of the jigsaw is borne by the workpiece, and the reciprocating saw is held by the user and bears the gravity of the reciprocating saw for cutting. [0003] Because of the different working methods, the jigsaw is small in size and is mostly used in relatively fine processes. It often has a large support plate to provi...

Problems solved by technology

In the process of work, users often need to alternate between these two tools, which is cumbersome and affects work efficiency, which brings great inconvenience to users

[0004] Some manufacturers have introduced multifunctional saws that can switch between reciprocating saws and jigsaws. However, the current multifunctional saws on the market have the motor installed in the handle. Due to the limited size of the motor itself, the size of the handle will be increased. Causes users to hold uncomfortable problems

The motor of the multi-function data released by some manufacturers is set outside the handle, but its structural design is unreasonable, resulting in a long tool, which cannot meet the needs of tool miniaturization
