The limit assembly 13 is used to prevent the rotating rod 10 from rotating without the action of external force after the adjustment of the adjustment assembly is completed, thereby improving the stability of the structure after adjustment; And a limiting plate 43 is arranged on one side of the sleeve plate 42 through the installation component, and the limiting plate 43 is L-shaped, which can further clamp and limit the tubular blank or the plate blank during positioning; In the embodiment of the present invention, the two vertical plates 2 are fixedly connected to the opposite sides thereof with motors 24, and the output end of the motor 24 is fixedly connected to one end of the electric push rod 3 through a connecting block. The motor 24 can drive the clamping mechanism 4 to rotate through the electric push rod 3, thereby driving the positioned musical instrument to rotate, so as to facilitate the adjustment of the punching position and improve the punching efficiency. In the embodiment of the present invention, a plurality of blanking holes 28 are opened on the top of the base 1, and waste chips generated during punching can enter the collection frame 29 through the blanking holes 28.

[0027] Through the above-mentioned structural setting, the hand nut 26 can be manually tightened to facilitate installation or disassembly between the pad 23 and the fixing plate 41. The operation is simple and quick, and the clamping mechanism 4 can be disassembled from the electric push rod 3 as a whole, which is convenient for disassembly, replacement or maintenance of the clamping mechanism 4 according to needs, further expanding the scope of use of the device.

[0028] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment compatible with the equipment can be used.

[0029] When in use, the musical instrument is placed between the two clamping mechanisms 4, the electric push rod 3 is started, and the two clamping mechanisms 4 are driven to position the musical instrument. At the same time, the limit plate 43 can further clamp and limit the tubular blank or the plate-shaped blank. During the positioning process, the friction plate 133 is driven away from the rotating rod 10 by rotating the screw rod 132, and the rotating rod 10 can be rotated. The rotating rod 10 drives the worm 11 to rotate, and the worm 11 drives the screw rod 5 to rotate through the worm gear 8. Under the guiding action of the slide plate 12, the connecting plate 7 drives the sleeve plate 42 to reciprocate on the screw rod 5, and the sleeve plate 42 can drive the limit plate 43 to move its position, so that the overall size of the clamping mechanism 4 can be adjusted, which is convenient for clamping musical instruments of different sizes. After the adjustment is completed, the screw rod 132 is rotated again to drive the friction plate 133 to clamp the rotating rod 10, limit the rotating rod 10, and prevent it from rotating without the action of external force. When the edge of the musical instrument is an irregular shape, by moving the clamping rods 20 on both sides of the mounting block 14 into the bending plate 17, the clamping rods 20 squeeze the springs 19, and after the fixing block 21 is removed, the two ends of the bending plate 17 can be rotated upward by ninety degrees, so that the bending plate 17 is transformed into a straight plate state, and it is pulled out of the mounting block 14. Then, the limiting plate 43 can be removed separately from the clamping mechanism 4, and vice versa, it can be installed, which is convenient for replacing the limiting plate 43 according to the shape of the musical instrument, increasing the scope of application, and by screwing the hand nut 26 out of the threaded rod 25 and taking out the anti-loosening gasket 27, the clamping mechanism 4 can be disassembled from the electric push rod 3 as a whole, which is convenient for disassembly, replacement or maintenance of the clamping mechanism 4 according to needs. After the positioning of the musical instrument is completed, the motors 24 on both sides are started at the same time, and the musical instrument can be driven to rotate through the clamping mechanism 4, which is convenient for adjusting the punching position. The waste chips dropped on the base 1 during punching enter the collection frame 29 through the blanking hole 28, and the collection frame 29 is pulled out of the base 1, which is convenient for centralized cleaning of the waste chips.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
