The working principle of the invention is as follows: when the leather products are to be processed and punched, the leather products are placed on the clamping assembly 32, the clamping assembly 32 is opened to clamp the leather products, the motor is started, the output end of the motor drives the transmission rod 212 to rotate, the transmission rod 212 can drive the drill bit 22 at the end of the transmission rod to rotate while rotating, the lifting assembly 5 is started, and the lifting assembly 5 drives the leather products to move upwards through the clamping assembly 32, so that the drill bit 22 can process and punch the leather products. The transmission rod 212 can drive the second gear 3114 to rotate while rotating, and the second gear 3114 is connected to the first gear 3113 to drive the rotation shaft 3112 to rotate. The rotating shaft 3112 can drive the gear 3116 on the surface to rotate while rotating, the gear 3116 is connected with the gear 3116 inside the sliding rack 3117 to drive the sliding rack 3117 to slide downward in the fixed rack 3115, the sliding rack 3117 can drive the sliding rod 3121 to move downward during the downward sliding process, the sliding rod 3121 drives the pressing plate 313 to move downward through the supporting block 3122, and when the pressing plate 313 contacts the leather product, the elastic member 3123 can apply a downward pushing force to the pressing plate 313 through the supporting block 3122, so that the pressing plate 313 can hold the leather product more stably. Avoiding the leather products from loosening in the punching process. The axis of rotation 3112 can drive connecting piece 421 at the pivoted in-process and rotate, and then connecting piece 421 drives sliding block 422 and rotates, and sliding block 422 is extension spring 424 in connecting piece 421 under the effect of centrifugal force to the through-hole 423 on sliding block 422 surface communicates with bleeder vent 412 on organism 1 surface, makes flabellum 411 can pass through-hole 423 and bleeder vent 412 exhaust organism 1 with the heat in the organism 1, realizes the heat dissipation to organism 1. When the rotating shaft 3112 stops rotating, the spring 424 pulls the sliding block 422 to slide towards the inside of the connecting member 421, so that the through hole 423 on the surface of the sliding block 422 is dislocated with the ventilation hole 412 on the surface of the machine body 1, the ventilation hole 412 on the surface of the machine body 1 is blocked, and external dust is prevented from entering the inside of the machine body 1.
