[0028] An internally threaded ring 47 is threadedly installed on the outer wall of the threaded rod 45. A connecting rod 48 is fixedly installed on the outer wall of the internally threaded ring 47. The top end of the connecting rod 48 is fixedly installed with a clamping plate 49. A plug 410 is fixedly installed on the side wall of the clamping plate 49. A gear 42 is rotatably installed on the inner wall of the top of the base 1. A first bevel gear 43 is fixedly installed at the bottom of the gear 42. The first bevel gear 43 is meshed with the second bevel gear 44. A toothed strip 41 is fixedly installed at the bottom of the punch body 2. The toothed strip 41 is meshed with the gear 42;

[0029] The specific implementation method is as follows: First, drive the positioning component 5 to make the triangular block 51 displace downward and retract into the base 1. At this time, the worker only needs to push the punch body 2. The punch body 2 drives the toothed strip 41 to displace. The toothed strip 41 is meshed with the gear 42. When the toothed strip 41 displaces, it drives the gear 42 to rotate. The gear 42 drives the first bevel gear 43 to rotate. The first bevel gear 43 is meshed with the second bevel gear 44, so that the first bevel gear 43 drives the second bevel gear 44 to rotate. The second bevel gear 44 drives the threaded rod 45 to rotate through the transmission rod. The outer wall of the threaded rod 45 is threadedly connected with the internally threaded ring 47. When the threaded rod 45 rotates, it drives the internally threaded ring 47 to displace on its outer wall. When the internally threaded ring 47 displaces, it drives the connecting rod 48 to displace. The connecting rod 48 drives the clamping plate 49 to displace, separating the clamping plate 49 from the punch body 2, and the plug 410 moves out of the jack provided on the side wall of the punch body 2.

[0030] The positioning component 5 includes a triangular block 51. A long rod 52 is fixedly installed at the bottom of the triangular block 51. A pressing plate 53 is fixedly installed at the bottom of the long rod 52. A telescopic rod 55 is fixedly installed at the bottom of the pressing plate 53. The bottom end of the telescopic rod 55 is fixedly connected with the inner wall of the bottom of the base 1. A spring 54 is sleeved on the outer wall of the telescopic rod 55. A travel rod 56 is fixedly installed on the side wall of the pressing plate 53. The travel rod 56 is slidably connected with the inner wall of the second travel groove. The other end of the travel rod 56 is fixedly installed with an integrated plate 57. A push plate 58 is fixedly installed on the outer wall of the integrated plate 57;

[0031] The specific implementation method is as follows: Before removing the punch body 2, it is necessary to first push the push plate 58. The push plate 58 drives the integrated board 57 to displace. The integrated board 57 drives the pressure plate 53 to displace downward through the stroke rod 56.

The long rod 52 drives the triangular block 51 to displace, and the triangular block 51 retracts into the base 1.

[0032] Working principle: First, drive the positioning component 5 to make the triangular block 51 displace downward and retract into the base 1. At this time, the staff only needs to push the punch body 2. The punch body 2 drives the toothed strip 41 to displace. The toothed strip 41 is meshed and connected with the gear 42. When the toothed strip 41 displaces, it drives the gear 42 to rotate. The gear 42 drives the first bevel gear 43 to rotate. The first bevel gear 43 is meshed and connected with the second bevel gear 44, so that the first bevel gear 43 drives the second bevel gear 44 to rotate. The second bevel gear 44 drives the threaded rod 45 to rotate through the transmission rod. The outer wall of the threaded rod 45 is threadedly connected with the internal thread ring 47. When the threaded rod 45 rotates, it drives the internal thread ring 47 to displace on its outer wall. When the internal thread ring 47 displaces, it drives the connecting rod 48 to displace. The connecting rod 48 drives the clamping plate 49 to displace, separating the clamping plate 49 from the punch body 2, and the pin 410 is removed from the jack provided on the side wall of the punch body 2. Before removing the punch body 2, it is necessary to first push the push plate 58. The push plate 58 drives the integrated board 57 to displace. The integrated board 57 drives the pressure plate 53 to displace downward through the stroke rod 56. The pressure plate 53 squeezes the spring 54 to make it in a compressed state. The pressure plate 53 also drives the long rod 52 to displace. The long rod 52 drives the triangular block 51 to displace, and the triangular block 51 retracts into the base 1.
