The working principle is as follows: during normal processing, leather shoes are placed between the two symmetrical fixing mechanisms 4, the leather shoes are pushed in with force, the arc-shaped plates 43 receive extrusion force to enable the pressure springs 42 inside the rectangular frames 41 to contract and accumulate elastic potential energy, after the leather shoes are pushed integrally, the pressure springs 42 release the elastic potential energy outwards to extrude the arc-shaped plates 43, the arc-shaped plates 43 on the two sides of the leather shoes extrude the leather shoes inwards, so that the leather shoes are fixed, at the moment, the rotating cover 23 is rotated manually to drive the threaded rod 22 to rotate, the gear 24 is driven to rotate, the rack plate 25 meshed with the outer side of the gear 24 is driven to move, the rack plate 25 moves outwards to extrude the upright rods 26, the upright rods move downwards in the limiting grooves, the pointer 27 is driven to move downwards, the tool rest 31 is driven to move downwards, the blade 35 is driven to move synchronously, at the moment, the number corresponding to the top part of the pointer 27 on the front side of the scale rod 28 is the distance of the blade 35, so that the thickness of each thinning is consistent, and the thickness of the thin film can be controlled at will.

When the thickness required to be thinned is determined, a power switch is started, the rotating wheel 12 is electrified and rotates, the first rotating rod 13 drives the second rotating rod 14 to rotate downwards, the telescopic rod 15 is extruded downwards, the push rod 16 is driven to move left and right in the cross plate 17, when the push rod moves left, the return spring on the left side of the push rod 16 is extruded, when the push rod moves right, the return spring assists the push rod 16 to move, and the energy loss is reduced, meanwhile, the thrust of the push rod 16 is buffered by a buffer arranged in the push rod 16, so that the leather shoes and parts are prevented from being damaged too much, the rubber push head 18 contacts the front surface of the leather shoes to extrude the leather materials attached to the front surface of the leather shoes, and the push rod 16 reciprocates, so the rubber pushing head 18 is driven to continuously extrude the leather material on the front surface of the leather shoes, and manual repeated beating is replaced, thereby achieving the purposes of replacing manual operation and improving the working efficiency.

Meanwhile, when the push rod 16 drives the rubber push head 18 to extrude the leather shoes in a reciprocating manner, the sawtooth plate 36 is also driven to reciprocate, the clamping plate 32 matched with the size of the clamping groove 37 is extruded, the clamping plate 32 slides into the clamping groove 37 along the inclined plane, at the moment, the sawtooth plate 36 contacts the tool rest 31 and pushes the tool rest to move, the blade 35 is driven to contact with the bottom of the leather shoes and cut into the bottom of the leather shoes, meanwhile, the top plate 34 is pushed to move towards one side close to the limiting column 33 in the tool rest 31 until the top plate contacts the limiting column 33 due to the reaction force, and the distance from the initial position to the contact with the limiting column 33 is equal to the distance from the top point of the blade 35 to the center of the sole, so that the situation that the blade tips at two sides continuously move after contacting and then collapse is prevented, and the thinning of the excessive part of leather shoe bottom adhered with leather materials is completed at the moment.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
