Abstract
The utility model relates to a puller, in particular to a vibrating puller. The utility model solves the problem that the conventional puller can hardly dismount tightly fitted parts fastened on shafts. The vibrating puller comprises a thrusting rod and claws connected with the thrusting rod, and a vibrator, the vibrating frequency of which can be regulated, is mounted on the end of the thrusting rod. When the vibrating puller is in use, parts to be dismounted violently resonate when the vibrating frequency is regulated into the resonance frequency range of the parts to be dismounted, so that the friction force between the parts to be dismounted is greatly decreased, and at the moment, when force is applied on the thrusting rod of the puller, the parts to be dismounted can be easily separated. Aimed at the circumstance that the friction force between the parts to be dismounted is overhigh, the utility model adopts the method of mounting the vibrator on the thrusting rod of the puller to forcibly vibrate the parts to be dismounted, thus greatly decreasing the friction force between the parts to be dismounted and thereby solving the problem that the conventional puller can hardly dismount parts.
