A plurality of detachable punches 4 are arranged along the circumference of the outer wall of the turntable 3. The detachable punches 4 are threadedly inserted into the turntable 3, and each detachable punch 4 has a different size, so the operator does not need to frequently replace the punches of the stamping equipment.

[0026] Two limit rods 5 are symmetrically inserted into the outer wall of the lower end of the connecting head 1, and a double-headed push rod 13 is arranged inside the connecting head 1. Both ends of the double-headed push rod 13 extend out of the connecting head 1 and are fixedly provided with a connecting plate 14. The lower end of the connecting plate 14 is fixedly connected to the outer wall of the limit rod 5. The double-headed push rod 13 is used to facilitate the movement of the connecting plate 14, and then the limit rod 5 is driven to move synchronously through the connecting plate 14.

[0027] Circular grooves 31 are provided at both ends of the turntable 3, and a plurality of first limiting grooves 32 are provided at the opening of the inner wall of the circular groove 31. The guide rod 7 is fixedly arranged on the inner wall of the circular groove 31, so that the limiting rod 5 can be inserted into the turntable 3 through the circular groove 31. When the limiting rod 5 is inserted into the circular groove 31, it is plugged into the first limiting groove 32, thereby fixing the turntable 3 in the assembly groove 2.

[0028] A through hole 21 is provided on the inner side of the assembly groove 2, and a second limiting groove 22 is provided on the inner wall of the through hole 21 facing one end of the turntable 3. The limiting rod 5 is movably inserted in the through hole 21, and a limiting block 51 corresponding to the first limiting groove 32 and the second limiting groove 22 is provided on the outer wall of the limiting rod 5. One end of the limiting block 51 is movably inserted in the first limiting groove 32, and the other end of the limiting block 51 is movably inserted in the second limiting groove 22. The limiting rod 5 is installed in the through hole 21. When the limiting block 51 is inserted in the first limiting groove 32 and the second limiting groove 22, it is convenient to fix the turntable 3 in the assembly groove 2. When the operator pulls the limiting rod 5 to move, the limiting block 51 separates from the first limiting groove 32 and moves into the second limiting groove 22, thereby causing the turntable 3 to lose its limit. At the same time, the end of the limiting rod 5 is still inserted into the circular groove 31, so that the turntable 3 can rotate.

[0029] One end of the limiting rod 5 passes through the connector 1 and is inserted into the turntable 3 and is provided with a one-way bearing sleeve 6. A guide rod 7 is fixedly provided in the turntable 3. A spiral groove 71 is provided on the outer wall of the guide rod 7 facing one end of the limiting rod 5. A transverse groove 72 is provided at the other end of the guide rod 7. The transverse groove 72 is connected to the spiral groove 71. When the limiting rod 5 moves, the one-way bearing sleeve 6 can be driven to rotate through the guide rod 7.

[0030] The guide rod 7 passes through the one-way bearing sleeve 6 and is movably connected with one end of the limit rod 5 inserted into the turntable 3. A semicircular block 61 is fixedly arranged on the inner side of the one-way bearing sleeve 6. The semicircular block 61 is slidably matched with the inner wall of the transverse groove 72 and the spiral groove 71. The outer wall of the one-way bearing sleeve 6 is provided with a transverse anti-grain pattern. When the operator pulls the limit rod 5 to move, the one-way bearing sleeve 6 is driven to move synchronously. At this time, the semicircular block 61 moves along the inner wall of the transverse groove 72. At this time, the one-way bearing sleeve 6 remains stationary, so that the operator can pull the limit rod 5 to move, and the limit block 51 is separated from the first limit groove 32 and moved into the second limit groove 22. When the semicircular block 61 moves along the inner wall of the spiral groove 71, the semicircular block 61 drives the inner ring of the one-way bearing sleeve 6 to rotate. At this time, the one-way bearing sleeve 6 is in a locked state, so the inner ring of the one-way bearing sleeve 6 drives the outer ring to rotate, and through the transverse anti-grain, the outer ring rotates and drives the turntable 3 to rotate synchronously, so as to adjust the position of the detachable punch 4; When the limit rod 5 is reset, it drives the one-way bearing sleeve 6 to move synchronously. At this time, when the semicircular block 61 moves along the inner wall of the spiral groove 71, the semicircular block 61 drives the inner ring of the one-way bearing sleeve 6 to rotate. At this time, the one-way bearing sleeve 6 is in an unlocked state, so the inner ring of the one-way bearing sleeve 6 rotates, and its outer ring and the turntable 3 remain stationary. When the semicircular block 61 moves along the inner wall of the transverse groove 72, the limit rod 5 drives the limit block 51 to move and plug into the first limit groove 32, thereby fixing the turntable 3 in the assembly groove 2.

[0031] In summary: first, the limit rod 5 is plugged into the turntable 3 to facilitate the assembly of the turntable 3 and the detachable punch 4 in the assembly groove 2. When the position of the detachable punch 4 needs to be adjusted, the limit rod 5 is pulled to move, thereby causing the turntable 3 to lose its limit position, and as the limit rod 5 moves, the one-way bearing sleeve 6 is driven to rotate through the guide rod 7, and then the turntable 3 is driven to rotate through the one-way bearing sleeve 6, thereby causing the turntable 3 to rotate ninety degrees, thereby realizing the replacement of the detachable punch 4; When the limit rod 5 is reset, it is plugged into the turntable 3, thereby fixing the turntable 3 in the assembly groove 2. When the limit rod 5 is reset, the guide rod 7 drives the one-way bearing sleeve 6 to rotate in the opposite direction. At this time, the one-way bearing sleeve 6 is in an unlocked state, so that the turntable 3 remains stationary, thereby reducing the possibility of resetting the detachable punch 4.
