[0029] See also Figure 1-4 The utility model provides a technical solution: a cloth punching machine that is easy to replace a punch, comprising a punching machine 1, the punching machine 1 is fixedly installed inside a housing 2, four fixing blocks 3 are fixedly installed on the output end of the punching machine 1, the bottom ends of the four fixing blocks 3 are all provided with connecting grooves 4, and the insides of the four connecting grooves 4 are all plugged with punching punches 5 through connecting devices;

[0030] A placement platform 6 is fixedly mounted on the front surface of the housing 2, and a rectangular groove 7 is provided on the upper surface of the placement platform 6 at positions corresponding to the four fixing blocks 3, and a supporting mechanism is provided inside the rectangular groove 7;

[0031] Among them, a cloth placing plate 8 is movably installed on the upper surface of the placing platform 6, and a clamping device is arranged on the cloth placing plate 8.

[0032] Furthermore, the connecting device includes a clamping block 9, which is slidably inserted into the interior of the connecting groove 4, a punching punch 5 is fixedly welded to the bottom end of the clamping block 9, and a limiting groove 10 is provided on the front surface of the clamping block 9.

[0033] Furthermore, a clamping rod 11 is slidably inserted into the front surfaces of the four fixed blocks 3, an operating ball 12 is fixedly installed at the front end of the four clamping rods 11, a return spring 13 is fixedly installed on the four operating balls 12, and the ends of the four return springs 13 away from the operating balls 12 are fixedly installed on the front surfaces of the corresponding fixed blocks 3.

[0034] Furthermore, the rear ends of the four clamping rods 11 extend to the inside of the connecting groove 4 , and the rear ends of the four clamping rods 11 are all inclined.

[0035] Furthermore, the support mechanism includes a support spring 14 , which is fixedly mounted at the inner bottom end of the rectangular groove 7 , and a support plate 15 is slidably mounted inside the rectangular groove 7 , and the lower surface of the support plate 15 is fixedly connected to the top end of the support spring 14 .

[0036] Furthermore, the clamping device includes two torsion spring rods 16, which are respectively fixedly mounted on the left and right sides of the upper surface of the cloth placing plate 8, and clamping plates 17 are fixedly mounted on the two torsion spring rods 16.

[0037] Working principle: push open the two clamping plates 17, use the elastic force of the torsion spring rods 16 on the left and right sides to clamp the cloth on the upper surface of the cloth placing plate 8, and then fix the cloth to facilitate the punching operation. When the punch needs to be replaced, pull the corresponding operating ball 12, the movement of the operating ball 12 drives the clamping rod 11 to move, and at the same time, the corresponding reset spring 13 is extended, and the clamping rod 11 is pulled out of the corresponding limit groove 10, so that the clamping block 9 is separated from the corresponding connection groove 4, and then the disassembly of the punch 5 is completed. When a new one is installed When punching the punch 5, the clamping block 9 is inserted into the interior of the connecting groove 4. Since the end of the clamping rod 11 away from the operating ball 12 is set as an inclined surface, the clamping block 9 pushes the clamping rod 11 inside the connecting groove 4 out of the interior of the connecting groove 4, and at the same time makes the corresponding reset spring 13 extend. When the limiting groove 10 on the clamping block 9 moves to the position of the clamping rod 11, the reset spring 13 contracts and drives the clamping rod 11 to enter the interior of the limiting groove 10, completing the installation of the punching punch 5, facilitating the disassembly and assembly of the punching punch 5, and improving the practicability of the device.
