A circular groove 22 is arranged at the center of the inside of the disc 15. A rotating ring 20 is movably connected to the front center of the inside of the disc 15. An annular chamber 24 is arranged around the inside of the disc 15, and planetary gears 25 are movably connected to the two sides, the top and the bottom of the annular chamber 24. Gear blocks 26 are arranged on the outer surface of the rear of the rotating ring 20. A micro motor 27 is installed at the upper center of the front end of the outer front end of the disc 15. Three sets of clamping push rods 5 are installed inside the front of the disc 15;

[0025] The planetary gear 25 is meshed with the gear block 26 by means of the tooth grooves on the surface, and the output shaft of the micro motor 27 is fixedly connected to the planetary gear 25. The planetary gear 25 surrounds the four sides of the outside of the rotating ring 20, and the rotation direction of the planetary gear 25 is opposite to that of the rotating ring 20;

[0026] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, the three sets of clamping push rods 5 installed inside the control rotating ring 20 fix the metal accessories pushed from the rear of the circular groove 22, and then turn on the micro motor 27 installed on the top of the front end of the disc 15. The micro motor 27 controls the rotation of the planetary gear 25 at the top of the annular chamber 24. Through the meshing transmission between the gear block 26 and the tooth groove, the planetary gear 25 rotates the rotating ring 20 installed in the front of the disc 15, forcing the internal clamped and fixed accessories to rotate at a certain angle and ensure the structural stability during rotation.

[0027] Embodiment 2: A movable groove 12 is vertically arranged at the center of the main frame 6, longitudinal chambers 7 are arranged between the top and bottom ends of both sides of the main frame 6, and transverse chambers 11 are horizontally arranged between the tops of the longitudinal chambers 7, a transverse shaft 9 is movably installed between the two sides of the transverse chamber 11, and the first gear 10 is welded and fixed on both sides of the outside of the transverse shaft 9, a motor 8 is installed at the upper left corner of the outside of the main frame 6, and the second gear 13 is movably connected to both sides of the lower part of the transverse chamber 11, a screw rod 14 is movably connected between the top and bottom ends of the longitudinal chamber 7, and the outside of the screw rod 14 is movably sleeved with a sleeve 16, and one side of the front end of the sleeve 16 is fixedly connected to the disc 15, and the top and bottom of both sides of the disc 15 are welded with a clamping block 21, and the surface of the clamping block 21 is movably inlaid with a ball bearing 23;

[0028] The first gear 10 rotates the screw 14 by meshing with the second gear 13. The sleeve 16 can slide vertically along the outer wall of the screw 14 by means of the internal thread. The side wall of the block 21 contacts the movable groove 12 through the ball 23. The block 21 is symmetrically assembled at the four corners of the disc 15.

[0029] Specifically, Figure 1 and Figure 4 As shown, the motor 8 at the upper left corner is turned on, and the output shaft of the motor 8 rotates the horizontal axis 9 in the horizontal chamber 11, forcing the first gear 10 to engage with the second gear 13 engaged at the bottom for transmission. Since the second gear 13 is fixedly connected to the top of the screw rod 14, the sleeve 16 can be synchronously forced to drive the front disc 15 to rise and fall vertically. The positions of the disc 15, the rotating ring 20 and the clamped metal are adjusted according to the installation height of the rear transmission mechanism and the front processing mechanism.

The waste generated during the processing of the accessories is collected through the through groove 17 at the side tubes 3 on both sides with the air collecting holes 4, and then enters the screen frame 18 through the through groove 17 at the bottom of the side tube 3 for isolation and filtration. Finally, the screen frame 18 can be pulled out for cleaning, thereby keeping the surface of the machine tool installed on the center frame clean enough.

[0032] Working principle: When the utility model is in use, first turn on the motor 8 at the upper left corner, and use the output shaft of the motor 8 to rotate the horizontal axis 9 in the horizontal chamber 11, forcing the first gear 10 to engage and transmit with the second gear 13 engaged at the bottom. Since the second gear 13 is fixedly connected to the top of the screw rod 14, the sleeve 16 can be synchronously forced to drive the front disc 15 to rise and fall vertically. The disc 15, the rotating ring 20 and the clamped metal position are adjusted according to the installation height of the rear transmission mechanism and the front processing mechanism. Blocks 21 with balls 23 are installed at the four corners behind the disc 15 as tools for fitting the movable groove 12. While changing the height of the disc 15 and other objects, this mechanism is prevented from getting stuck. Then the three sets of clamping push rods installed inside the rotating ring 20 are controlled. 5 fixes the metal fittings pushed from the rear of the circular groove 22, and then turns on the micro motor 27 installed at the top of the front end of the disc 15, and uses the micro motor 27 to control the rotation of the planetary gear 25 at the top of the annular chamber 24. Through the meshing transmission between the tooth block 26 and the tooth groove, the planetary gear 25 rotates the rotating ring 20 installed at the front of the inside of the disc 15, forcing the fittings clamped and fixed inside to rotate at a certain angle. The screen frame 18 with a gauze at the bottom is pre-inserted horizontally into the storage frame 2, and the fan 19 installed below the base 1 is turned on. The waste generated during the processing of the fittings is collected through the through groove 17 at the side pipes 3 on both sides with the air collecting holes 4, and then enters the screen frame 18 through the through groove 17 at the bottom of the side pipe 3 for isolation and filtration, and finally the screen frame 18 is pulled out for cleaning.
