[0002] An electric reciprocating saw is a device used to cut materials, usually driven by electricity. It converts electricity into mechanical energy for the reciprocating motion of a reciprocating linear motor. The reciprocating motion of the linear motor drives the saw blade to reciprocate. Compared with traditional hand saws, electric reciprocating saws have the advantages of simple operation and labor saving.

[0003] In the related art, a Chinese utility model patent with authorization announcement number CN209867554U discloses a dual-purpose electric reciprocating saw, which includes a machine head, a saw blade assembly connected to the top of the machine head, a handle connected to the bottom of the machine head, and a battery pack plugged into the handle.

The top surface of the battery pack is removably and horizontally slidably plugged into the bottom surface of the handle. A mounting piece is provided on the bottom surface of the battery pack, and the top end of the telescopic rod is removably plugged into the mounting piece.
