The card grooves 41 can be inserted by the second wedge block 74, and then the assembly plate 4, the assembly disk 5 and the shaft arm 6 are fixed.

[0028] The interior of the assembly plate 4 is connected to the shaft arm 6 through a bearing, and the outside of the shaft arm 6 can be equipped with conical teeth. The shaft arm 6 is driven to rotate by cooperating with the motor through the matching conical teeth, thereby changing the state of the processing parts and the bumper inside the assembly disk 5. The shaft arm 6 is a round tube with closed ends, and a guide plate is embedded in the interior of the piston 72. The guide plate is slidably connected to the shaft arm 6, and the shaft arm 6 can generate airflow when the piston 72 returns.

[0029] Square grooves 61 are evenly distributed on both ends of the outside of the shaft arm 6, and the square grooves 61 are adapted to the card slots 41. The square grooves 61 can be inserted by the second wedge block 74, and then the assembly plate 4, the assembly disk 5 and the shaft arm 6 are fixed. The outside of the shaft arm 6 is sleeved with the assembly disk 5, and the outside of the assembly disk 5 is evenly distributed with flanges 51. The inner ends of the shaft arm 6 are connected to the limiting mechanism 7.

[0030] The limiting mechanism 7 includes a cylinder 71 and a second wedge block 74. The cylinder 71 can drive the piston 72 to descend. The top of the cylinder 71 is connected to an assembly frame 78, which is connected to the shaft arm 6. The assembly frame 78 can support and fix the cylinder 71. The output end of the cylinder 71 is connected to a piston 72, which can drive the first wedge block 73 to descend. The piston 72 is slidably connected to the shaft arm 6.
