[0039] The punching mechanism comprises a punching drill 104 disposed on the frame 100, and the punching drill 104 is provided with a position adjusting member for adjusting its position on the frame 100;

[0040] The positioning mechanism includes a plurality of positioning parts spaced apart on the lower surface of the flow turntable 101. The frame 100 is provided with a linearly movable abutment part. When the abutment part abuts against one of the positioning parts, the drilling drill 104 starts the drilling operation.

[0041] The product moves toward the pushing piece through the conveying channel 102. When the product moves to the pushing position of the pushing piece, the pushing piece moves in a straight line to push the product toward the direction of the clamping jaws 102 and push it to the clamping position of one of the clamping jaws 102. The clamping jaws 102 drive the product to be clamped and fixed. Then the rotating disk 101 drives the clamping jaws 102 to rotate in a circular direction to move it to the drilling drill 104. The drilling drill 104 works to drill holes in the product. When the rotating disk 101 rotates to drive the clamping jaws 102 with the product to move to the drilling drill 104, the empty clamping jaws 102 move to the pushing piece to receive the next product, thereby reducing the waiting time in the entire drilling process and improving the drilling efficiency. In order to ensure the positioning accuracy of the product, a positioning mechanism is also provided on the frame 100. There are multiple positioning parts, and the number of positioning parts corresponds to the number of clamping jaws 102, so as to ensure the sustainable operation of the drilling drill 104 and improve the drilling efficiency of the product.
