Technical Field
[0001] The utility model relates to the technical field of reciprocating saws, and particularly relates to a lightweight reciprocating saw. Background Art
[0002] A reciprocating saw, as a cutting tool, is used to cut workpieces. A reciprocating saw generally includes a reciprocating rod that can be driven to reciprocate at a high speed within a preset range, and it can connect working accessories such as saw blades to cut workpieces.
[0003] In order to facilitate users to carry and use in various occasions, the existing technology has developed a lightweight reciprocating saw. However, in the process of realizing the lightweight of the reciprocating saw, the thickness and size of some components are inevitably sacrificed. This sacrifice has led to a decrease in the stability of the reciprocating saw during actual sawing operations. Specifically, due to the reduction of the component thickness, the saw blade is more likely to vibrate during high-speed reciprocating motion, thereby affecting the sawing accuracy and efficiency. In addition, the reduction in size may also lead to a decrease in the strength and durability of the overall structure, thus shortening the service life of the reciprocating saw. For this reason, we propose a lightweight reciprocating saw. Summary of the Utility Model
