Reciprocating saw and its operation method

Abstract

The invention relates to a reciprocating saw, which includes a shell, a motor, a saw blade, a clamp and a main handle. The shell is provided with a front end and a back end; the motor is arranged in the shell; the saw blade extends out of the front end of the shell, and is driven by the motor to implement reciprocating cutting actions basically along the front and back directions relative to the shell; the clamp is used for clamping workpieces, arranged near the front end of the shell and can pivot relatively to the shell along a pivotal axis; the main handle is arranged at the back end of the shell and used to be held during cutting. The reciprocating saw is characterized by also including an auxiliary handle which is connected with the clamp and extends backwards for being held during cutting; moreover, during cutting, the main handle and the auxiliary handle are respectively forced and pressed to lead the shell and the clamp to relatively rotate along the pivotal axis of the clamp.

Description

technical field [0001] The present invention relates to a reciprocating saw. In particular, it relates to a reciprocating saw with a clamp. [0002] Background technique [0003] Reciprocating saws are a common tool for cutting pipes, wood and other workpieces. However, direct use of reciprocating saws to cut workpieces often has disadvantages such as large vibration and low cutting accuracy. Therefore, there has been a reciprocating saw with clamps, such as US Pat. Clamp workpieces with different specifications and sizes. After the clamp clamps the workpiece, the reciprocating saw is rotated relative to the clamp to cut the workpiece. Due to the pivotal connection between the clamp and the reciprocating saw, the reciprocating saw can only cut in the determined direction of the workpiece to be cut, which solves the problems of large vibration and low precision when the reciprocating saw cuts the workpiece place. [0004] However, existing reciprocating saws and their cla...

Problems solved by technology

However, devices such as vices are usually large, inconvenient to move, and not suitable for narrow workplaces, which brings many limitations to the cutting work of reciprocating saws.

For another example, the existing reciprocating saw clamps usually use screw rods to tighten the splint. It is often difficult for users to determine whether the splint has been clamped tightly enough. If the clamp is loose, the cutting will be unstable or even dangerous. If the grip is too tight, it will be difficult to release the splint after cutting
