[0027] Refer to Figure 3 、 Figure 7 and Figure 8 The moving assembly includes a connecting plate 6 which is fixedly connected to the right side of the top of the base 1. Guide rails 7 are respectively arranged on the front and rear sides inside the connecting plate 6. The guide rails 7 are slidably connected with the moving block 301. Through the guide rails 7, the moving block 301 can move along the connecting plate 6; Specifically, through the guide rails 7, the moving block 301 can be allowed to move along the connecting plate 6, and the position of the milling cutter 302 can be adjusted to facilitate the fixing of the valve.

[0028] Refer to Figure 3 、 Figure 5 and Figure 6, electric rollers 21 are rotatably connected to both the upper and lower sides inside the clamping plate 210. A first belt 13 is arranged on the outer side of the electric rollers 21. The multiple electric rollers 21 are all drivingly connected through the corresponding first belts 13. The first belt 13 can improve the rotational synchronism of the electric rollers 21, and the rotation of the electric rollers 21 can adjust the rotational position of the valve; Specifically, by starting the electric rollers 21, the valve can be driven to rotate and adjust along the clamping plate 210 to increase the processing range. At the same time, the transmission of the first belt 13 can improve the stability and synchronism of the rotation of the electric rollers 21.

[0029] Refer to Figure 3 , Figure 5 and Figure 6 , connection blocks 10 are fixedly connected to the outer periphery of the hollow cover 201. The bottom of the connection blocks 10 is fixedly connected to the electric telescopic rods 9. By starting the electric telescopic rods 9, the height position of the hollow cover 201 can be adjusted, and by starting the electric turntable 8, the angular orientation of the hollow cover 201 can be adjusted; a groove 11 is formed inside the hollow cover 201, and an inclined panel 12 is fixedly connected to the inside of the groove 11. The impurities received by the inclined panel 12 can be discharged through the groove 11; Specifically, by starting the electric turntable 8, the rotational position and orientation of the hollow cover 201 can be adjusted. Then, the electric telescopic rods 9 are started to extend and retract, thereby pushing the connection blocks 10 and the hollow cover 201 to move up and down, so as to adjust the orientation and height position of the valve, further increasing the processing range of the valve. The inclined panel 12 can slide the dust and impurities entering the hollow cover 201 to both sides through its inclined surface, and then discharge them from the groove 11 to prevent dust and impurities from accumulating inside the hollow cover 201.

[0030] Working principle: By starting the first motor 202 to drive the threaded rod 203 to rotate along the mounting plate 211, the hollow plate 208 and the clamping plate 210 thereon move to position the valve. Subsequently, the second motor 204 is started to drive the cross plate 205 to rotate, so as to drive the first rotating wheel 206 to rotate through the cross plate 205. Through the transmission of the second belt 207, the second rotating wheel 209 and the hollow cover 201 are driven to rotate to adjust the angle of the valve. At the same time, the sliding of the cross plate 205 and the first rotating wheel 206 can ensure that it does not affect the movement of the hollow plate 208, so as to fix valves of different specifications and adjust the angle and position of the valve; Moreover, by starting the rotation of the milling cutter 302, the valve can be processed. At this time, the rotation of the milling cutter 302 will also synchronously drive the rotation of the rotating rod 303 and the fan blades 306 thereon. When the fan blades 306 rotate, they can drive the air flow, so that the impurities generated during the processing of the milling cutter 302 are sucked into the air inlet groove 308 along with the suction of the air flow. At this time, the filter screen 305 can intercept the impurities to prevent them from affecting the rotation of the fan blades 306. The intercepted impurities will enter the storage box 307 in the reserved groove 304 for easy collection and cleaning of the impurities; Finally, by starting the bidirectional motor 401, the threaded column 402 can be driven to rotate. At this time, with the rotation of the threaded column 402, the plug block 403 can be pushed to move. At this time, with the movement of the plug block 403, the rack 406 thereon can be synchronously driven to move, so that when the plug block 403 moves, the device can be plugged and fixed through the plug block 403. At the same time, through meshing, the gear 405 and the rotating cover 404 can be pushed to rotate and retracted into the base 1. When the plugging and fixing cannot be carried out, when the plug block 403 retracts, the rotating cover 404 will also be reset. At this time, rotating the knob 409 can drive the threaded block 407 to rotate, thereby driving the positioning plate 408 to move up and down to cooperate with the rotating cover 404 to clamp and fix the device, and the fixing method of the device can be adjusted according to requirements.
