[0040] Reference Figure 4-Figure 6 The top of the electric push rod 77 is fixedly connected to the top of the inner wall of the support frame 2. The electric push rod 77 is symmetrically distributed in two groups. The fixing effect of the electric push rod 77 prevents the electric push rod 77 from falling off. The top inner wall of the semicircular block 72 is elastically connected to the wedge block 73 through the limit spring 74. The elastic force of the limit spring 74 makes the wedge block 73 always maintain the clamping effect with the clamping groove without being affected by external force, thereby limiting the semicircular block 72 so that the left cutting knife 71 and the right cutting knife 75 are fixed. A clamping groove is provided on the top of the arc block 76. The semicircular block 72 and the arc block 76 are symmetrically distributed in two groups. The right side of the semicircular block 72 is plugged into the left inner wall of the arc block 76. The left cutting knife 71 and the right cutting knife 75 are both in the shape of a half sole. By installing the left cutting knife 71 and the right cutting knife 75 on the electric push rod 77, the left cutting knife 71 and the right cutting knife 75 can form a cutting knife in the shape of a complete sole, so as to facilitate cutting the edge of the sole, and the inner wall size of the cutting knife in the shape of the sole is the same as the size of the sole. The cutting edges of the left cutting knife 71 and the right cutting knife 75 are both opened on the inner side. By setting the cutting edges on the inner side, the cutting accuracy of the left cutting knife 71 and the right cutting knife 75 is improved, and the error is reduced.

[0041] Reference Figure 1-Figure 3The top of the motor 691 is fixedly connected to the bottom of the workbench 1, and the fixing effect of the motor 691 prevents the motor 691 from falling off. The outer wall of the gear 692 is rotatably connected to the inner wall of the workbench 1, and the outer wall of the gear 692 is meshed with the outer wall of the gear ring 693. Due to the meshing transmission effect of the gear 692 and the gear ring 693, when the gear 692 rotates, the gear ring 693 can be driven to rotate. The limiting component 68 includes a clamping block 681, and the top of the clamping block 681 is elastically connected to the top inner wall of the support column 610 through a spring 682. Through the elastic force of the spring 682, the clamping block 681 always maintains the clamping effect with the cylindrical groove without being affected by external force, thereby limiting the cylindrical rod 63. The top of the clamping block 681 is fixedly connected with a pull rod 683, and the fixing effect of the pull rod 683 prevents the pull rod 683 from falling off. A cylindrical groove is provided at the top left end of the cylindrical rod 63.

[0042] Reference Figure 2 One end of the spring 682 is fixedly connected to the top inner wall of the support column 610, and the other end of the spring 682 is fixedly connected to the top of the block 681. The fixing effect of the spring 682 keeps the block 681 fixed to prevent the block 681 from falling off. The outer wall of the block 681 is slidably connected to the top inner wall of the support column 610. The sliding effect of the block 681 allows the block 681 to be engaged or released from the cylindrical groove. The outer wall of the block 681 is engaged with the inner wall of the cylindrical groove. The engagement effect of the block 681 and the cylindrical groove allows the support column 610 to limit the cylindrical rod 63. The outer periphery of the pull rod 683 penetrates and is slidably connected to the top inner wall of the support column 610. The sliding effect of the pull rod 683 drives the block 681 to slide.

[0043] Reference Figure 5 The locking cam 77 is in the form of a bolt, and the bolt has a camming effect on the locking cam 73. The locking cam 77 is in the form of a bolt, and the bolt has a time lapse. When the locking cam 77 is in the form of a bolt, the locking cam 77 is in the form of a bolt.

[0044] Working principle: when the staff needs to cut the edge of the sole, the staff pulls the pull rod 683 upward, so that the pull rod 683 drives the block 681 to move upward, and then the cylindrical rod 63 slides to the left along the inner wall of the cylindrical tube 61, and at the same time drives the block 64 to squeeze the reset spring 62, so that the cylindrical rod 63 drives the movable frame 65 to move to the left to the leftmost end, thereby driving the grinding block 66 to move to the left, and releases the pull rod 683, so that the block 681 is engaged with the cylindrical groove under the elastic force of the spring 682, and at the same time the cylindrical rod 63 is limited, so that the grinding block 66 remains fixed, and the staff places the sole on the top of the supporting mold 3, starts the electric telescopic rod 5, and drives the pressing mold 4 to move downward through the electric telescopic rod 5, so that the pressing mold 4 and the supporting mold 3 press and fix the sole, and then the staff starts the electric push rod 77, and drives the left cutting knife 71 and the right cutting knife 75 to move downward through the electric push rod 77 to cut the edge of the sole.

[0045] When the cutting work is completed, the staff controls the electric push rod 77 to retract upward, so that the left cutting knife 71 and the right cutting knife 75 move upward, and the staff pulls the pull rod 683 upward to release the limiting effect on the cylindrical rod 63. Through the elastic force of the reset spring 62, the stopper 64 drives the cylindrical rod 63 to slide to the right, so that the movable frame 65 drives the grinding block 66 to move to the right, so that the grinding block 66 contacts the edge of the sole, and the micro motor 67 is started to drive the grinding block 66 to rotate and grind. By starting the motor 691, the gear 692 is driven to rotate, so that the gear ring 693 rotates, thereby driving the support column 610 to rotate around the center of the gear ring 693, and at the same time driving the grinding block 66 to grind around the edge of the sole.

[0046] When the tool 72 is in the state of being rotated, the tool 72 is in the state of being rotated, and the tool 72 is in the state of being rotated, and the tool 72 is in the state of being rotated, and the tool 72 is in the state of being rotated, and the tool 72 is in the state of being rotated, and the tool 72 is in the state of being rotated, and the tool 72 is in the state of being rotated, and the tool 72 is in the state of being rotated, and the tool 72 is in the state of being rotated, and the tool 72 is in the state of being rotated, and the tool 72 is in the state of being rotated,
