[0030] Specifically, a rotary motor 6 is mounted on the top surface of the base frame 1, and the output end of the rotary motor 6 is fixedly connected to one side of the outer wall of the side gear 5.

[0031] In this embodiment, the side gear 5 is rotated by the rotary motor 6, which in turn drives the main gear 4 to rotate.

[0032] Working principle: The base frame 1 is equipped with support columns 2 and tray frame 3. The movable turntable is located on the top surface of the tray frame 3 and can rotate. The rotary motor 6 drives the side gear 5 to rotate, which in turn drives the main gear 4 and the movable turntable to rotate, thereby drilling holes in the fixed guitar inner ring. After the guitar inner ring is placed on the movable turntable, the rotary cylinder 11 is activated. The rotary cylinder 11 drives the upper turntable 8 to rotate, causing the connecting rod 9 to drive the fixing plate 10 to move linearly along the limiting groove, thereby fixing the guitar inner ring. The fixing plate 10 has a recessed opening on one side to avoid contact with the drilling machine 15. Then, the drilling machine 15 drills holes in the fixed guitar inner ring. After one drilling is completed, the cylinder 13 retracts, the rotary motor 6 drives the movable turntable to rotate, causing the guitar inner ring to rotate, thereby drilling holes in other positions. The positioning effect is better, and the drilling efficiency is higher, which is beneficial to production operations.

[0033] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field.
