Reciprocating cutting tool

Abstract

The invention provides a reciprocating cutting tool, which is used for cutting workpieces and comprises a handle, a casing, a motor, a reciprocating lever and a limiting part, wherein the casing is pivotally connected with the handle, the motor is contained in the casing, the reciprocating lever is driven to reciprocate by the motor, and the limiting part is arranged on the casing. A locking part is detachably mounted on the handle, can be matched with the limiting part and is operably placed at a locking position and a releasing position, wherein the locking position is used for limiting relative rotation of the casing and the handle, the releasing position is used for allowing relative rotation of the casing and the handle, and the locking part at least partially encloses the limiting part. The reciprocating cutting tool has the advantages that the rotary resistance between the locking part and the limiting part is increased, and the positions of the locking part and the limiting part are stably locked.

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, most of the multifunctional saws on the market currently use a positioning pin to cooperate with a disc surface with grooves to limit the relative rotation of the housing to achieve multiple functions. The functional saw is locked, but after using it for a period of time, the positioning pin and the edge of the groove are worn, and the positioning begins to be unstable, which seriously affects the normal use of the user
