The invention relates to a reciprocating saw and a transmission mechanism suitable for the reciprocating saw. The reciprocating saw comprises a slide bar, a motor and the transmission mechanism. The slide bar is fixedly connected with a saw blade. The motor drives the slide bar to move through the transmission mechanism. The transmission mechanism comprises a driving part and a connecting rod. The motor drives the driving part. The connecting rod is connected with the slide bar and the driving part. The driving part is provided with a mounting hole. At least one part of the connecting rod stretches into the mounting hole in a slideable mode. Grease is contained in the mounting hole. A channel allowing the grease to pass through is formed in the connecting rod. The channel communicates with the inside and outside of the mounting hole. The reciprocating saw is long in service life.
Description
technical field [0001] The invention relates to a reciprocating saw and a transmission mechanism suitable for the reciprocating saw. Background technique [0002] In the prior art, a reciprocating saw includes a connecting rod and a swing rod bearing, the swing rod bearing is formed with a mounting hole, and the connecting rod reciprocates in the mounting hole. When the reciprocating saw is working, the swing rod bearing will drive the connecting rod to reciprocate continuously in the installation hole. In this way, there will be strong friction between the connecting rod and the swing rod bearing. The wear of the bearings will affect the service life of the reciprocating saw. Contents of the invention [0003] To solve the above problems, the object of the present invention is to provide a reciprocating saw with a long service life. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is as follows: [0005] A reciprocati...
