Abstract:
The present utility model relates to a reciprocating saw, comprising: a housing provided with a mounting cavity; a reciprocating mechanism, the reciprocating mechanism being provided in the mounting cavity and comprising a reciprocating shaft, a sleeve and a first guiding assembly, wherein the sleeve is sleeved on the reciprocating shaft, a guiding portion is provided in the circumferential direction of the reciprocating shaft, and the guiding portion is in guiding fit with the sleeve by means of the first guiding assembly; a saw blade assembly connected to one end of the sleeve; a driving assembly at least partially provided in the mounting cavity, the driving assembly being in driving connection with the reciprocating shaft and configured to drive the reciprocating shaft to rotate so as to drive the sleeve to perform reciprocating movement in the length direction of the saw blade assembly. According to the reciprocating saw, the reciprocating shaft and the sleeve are in guiding fit with each other by means of the first guiding assembly, so as to convert rotation of the reciprocating shaft into reciprocating movement of the sleeve, thereby facilitating the elimination of a deflecting force, reducing power loss of the driving assembly, facilitating the improvement of transmission efficiency, and further improving the quality of use of the reciprocating saw.
