After being energized, the electromagnet 706 attracts the iron block 704, so that the two second sealing plates 306 move away from each other, and at the same time, the second spring 703 is compressed.

[0034] See also Figure 2 and Figure 6 The on-off mechanism includes a fixed cover 801 fixedly inserted into the side wall of the U-shaped tube 206, and a sealing plate 802 is inserted into the fixed cover 801. A circular hole 803 is opened on the side wall of the sealing plate 802, and a third spring 804 is fixedly connected between the sealing plate 802 and the fixed cover 801.

The side wall of the connecting plate 805 is rotatably connected to a push block 806 through a one-way rotation mechanism, and the top and bottom of the push block 806 are both provided with a second inclined surface 807. When the first stopper 303 moves upward, When moving, the connecting plate 805 is driven to move upward, and the pushing block 806 is driven to move upward through the one-way rotation mechanism. When the second inclined surface 807 above is against the bottom of the sealing plate 802, the pushing block 806 can be pushed to rotate downward. When the first stop block 303 moves downward, when the second inclined surface 807 below is against the top of the sealing plate 802, the pushing block 806 will not rotate, so that the sealing plate 802 can be pushed to slide into the fixed cover 801, so that the circular hole 803 is aligned with the U-shaped tube 206. At this time, the on-off mechanism is opened.

[0035] See also Figure 6 and Figure 7The one-way rotation mechanism includes two symmetrically arranged second fixed blocks 901 fixedly connected to the side walls of the connecting plate 805, and the side walls of the second fixed blocks 901 are rotatably connected to the rotating blocks 903 through the rotating pins 902. The rotating blocks 903 are fixed to the side walls of the pushing blocks 806, and the side wall fixing sleeves of the rotating pins 902 are provided with gears 904.

The racks 905 are meshed with the gears 904, and the side walls of the second fixed blocks 901 are fixedly connected to the second stoppers 906. When the first stopper 303 moves upward, the connecting plate 805 is driven to move upward, and the pushing blocks 806 are driven upward by the one-way rotation mechanism. When the second inclined surface 807 above is aligned with the sealing plate 8 02, can push the pushing block 806 and the rotating block 903 to rotate downward, so that the rotating pin 902 and the gear 904 rotate counterclockwise. At the same time, the rack 905 moves upward. At this time, it will not push the sealing plate 802 to move. When the first stop block 303 moves downward, it drives the connecting plate 805 and the pushing block 806 to move downward. When the second inclined surface 807 below abuts the top of the sealing plate 802, the rack 905 abuts the top of the second stop block 906, so that the rack 905 cannot move downward, the gear 904 and the rotating pin 902 cannot rotate clockwise, and the pushing block 806 and the rotating block 903 cannot rotate clockwise, thereby pushing the sealing plate 802 to slide into the fixed cover 801.

[0036] See also Figure 7 The reset assembly includes a support block 1001 fixedly connected to the side wall of the second fixed block 901, and two symmetrically arranged fixed rods 1002 are fixedly connected between the support block 1001 and the second stop block 906.

[0037] Working principle: When in use, the grinding head 111 is driven to rotate by the electric spindle 110 of the grinding machine to realize the grinding operation, and the mounting seat 12 and the milling head 13 are driven to rotate by the motor 11 to perform the milling operation, which has stronger functionality. Moreover, after the processing is completed, the grinding head 111 or the milling head 13 can be rotated to a vertically upward state by rotating the swing head 109. When the grinding head 111 or the milling head 13 abuts against the first inclined surface 305, the first sealing plate 301 can be pushed to move upward. At the same time, the first stopper 303 is driven to move upward by the guide rod 302, and the buffer 304 is deformed. At the same time, when the first stopper 303 moves upward, the connecting plate 805 is driven to move upward, and the pushing block 806 is driven to move upward through the one-way rotation mechanism. When the second inclined surface 807 above abuts against the bottom of the sealing plate 802, the pushing block 806 and the rotating block 903 can be pushed to rotate downward, so that the rotating pin 902 and the gear 904 are engaged. When the second inclined surface 807 below abuts the top of the sealing plate 802, the rack 905 abuts the top of the second stopper 906, making the rack 905 unable to move downward, the gear 904 and the rotating pin 902 unable to rotate clockwise, and the pushing block 806 and the rotating block 903 unable to rotate clockwise, thereby pushing the sealing plate 802 to slide into the fixed cover 801, so that the circular hole 803 is aligned with the U-shaped tube 206. At this time, the air extraction operation can be performed through the U-shaped tube 206.

[0038] At the same time, when air enters the installation box 501, it can impact the surface of the rotary fan 602, causing the rotary fan 602 to rotate, thereby driving the driving shaft 601 to rotate. When the driving shaft 601 rotates, the cam 503 can be driven to rotate through the rotating shaft 502. When the tip of the cam 503 is against the side wall of the movable cover 201, the movable cover 201 can be pushed to move. At the same time, the first spring 403 is stretched. When the tip of the cam 503 passes over the side wall of the movable cover 201, the movable cover 201 can move and reset under the action of the first spring 403. This reciprocating process can enable the movable cover 201 to drive the brush 203 to move. The brush 203 can clean the surface of the grinding head 111 or the milling head 13. At the same time, dust collection can be performed through the through hole 202, so that the surface of the grinding head 111 or the milling head 13 can be automatically cleaned, thereby ensuring its effectiveness and service life.

[0039] When cleaning the grinding head 111 or the milling head 13, the electromagnet 706 is energized. After being energized, the electromagnet 706 attracts the iron block 704, so that the two second sealing plates 306 move away from each other. At the same time, the second spring 703 is compressed. When the grinding head 111 or the milling head 13 rotates to a vertical state, the first sealing plate 301 can move downward and reset under the action of the buffer 304. Then, the electromagnet 706 is de-energized. At this time, the two second sealing plates 306 can move closer to each other under the action of the second spring 703, so that the two semicircular plates 308 can be against the side wall of the grinding machine electric spindle 110 or the mounting seat 12. At the same time, the telescopic cover 307 is deformed, so that the grinding head 111 or the milling head 13 can be sealed and protected to prevent it from being contaminated by dust, water stains, etc. and damaged by collision, thereby ensuring its effectiveness and life.
