[0017] Compared with the prior art, the present invention has the following significant advantages:

[0018] First, the present invention holds two cover plates and slides them in opposite directions. During the sliding process, the two cover plates will drive the two right-angle racks to slide. The sliding of the two right-angle racks can drive the two gears to rotate. When the two gears rotate, a plurality of tooth plates meshing with the two gears will be lowered, thereby driving the mounting plate and the scanner body arranged above the mounting plate to be synchronously lowered through the support plate. When the mounting plate drives the scanner body to descend into the protective box, the two right-angle racks are respectively disengaged from the two gears. At this time, the bottom ends of the two tooth plates are in contact with the inner bottom wall of the protective box to lock the two gears, so that the scanner body can be locked. The housing is stored and protected when it is displaced; at the same time, the two cover plates continue to drive the two right-angle racks to move toward each other, and the air pipes 1 and 2 can be pushed to move. Under the action of the guide groove, the air pipe 1 moves to the lowest point of the guide groove and is flush with the air pipe 2. At this time, the two suction cups are respectively adsorbed on both sides of the housing, and the telescopic connecting rod 1 and the telescopic connecting rod 2 continue to drive the air pipes 1 and 2 to move, which will make the push blocks set at the bottom ends of the vertical rods 1 and 2 contact and squeeze the two stoppers respectively, and pull the two pistons to move again, so that negative pressure is generated inside the two suction cups adsorbed to the sides of the housing, thereby improving the adsorption effect and further improving the storage and protection effect.

[0019] Second, after the lens and the control display screen are cleaned and the scanner body is stored and protected, the scanner body is controlled by its internal rotating motor and rotates. During the rotation, the arc block arranged on its surface squeezes the baffle rod and drives the slide plate to descend. When the lens is rotated downward, the arc block is separated from the baffle rod, and the slide plate drives the protective brush ring to reset, thereby wrapping and protecting the lens and improving the protection effect of the scanner body.

[0020] Thirdly, when the two right-angle racks continue to move, the telescopic connecting rod 1 drives the slotted moving plate to move, and then drives the movement of the air pipe 1, and the telescopic connecting rod 2 drives the air pipe 2 to move. During the movement of the air pipe 1 inside the guide groove, the sphere 1 arranged on the vertical rod 1 will reciprocately contact with the sphere 2, and then squeeze the sphere 1 to drive the vertical rod 1 to slide inside the circular groove 1, and then drive the piston to slide, and extract gas into the air pipe 1, until it slides to the inner wall of the circular groove 1. At this time, the sphere 1 is blocked and reversely squeezes the sphere 2 to drive the sliding rod to rise, thereby causing the separation between the sphere 1 and the sphere 2. The piston is reset by the reset spring and will be reset instantly. The air inside the air pipe 1 will be ejected, and the dust on the surface of the control display screen set on the side of the scanner body can be cleaned;

[0021] Fourthly, in the present invention, one of the right-angle racks drives the adapter rod to pass through the through hole and insert it into the adapter hole provided on the wiping block. The trapezoidal block provided can limit the wiping block and push the wiping block to move. When the wiping block is pushed and moved, it will pass through the lens surface of the scanner body, thereby wiping the lens of the scanner body.

[0022] The problem that if the scanner needs to be moved to another location during a single measurement, in order to ensure that the scanner will not be damaged during the movement, it must be removed from the bracket and reinstalled at the designated location. During the frequent disassembly and assembly, the hands of the personnel may come into contact with the lens of the 3D scanner, which may cause contamination or even damage to the lens, affecting the measurement accuracy. At the same time, the frequent disassembly and assembly affects the measurement efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] like Figure 1 and Figure 8As shown, a shell 11 is provided on the upper surface of the mounting plate 10, and a control display screen 12 is provided on one side of the shell 11. The shell 11 is connected to the mounting plate 10 through a fixed base, and the fixed base and the mounting plate 10 are connected by bolts. A scanner body 13 is rotatably provided inside the shell 11. The scanner body 13 is a three-dimensional radar scanner. The existing three-dimensional radar scanner can realize flexible rotation of the lens in the horizontal and vertical directions. This design allows the laser radar to scan in a larger range and obtain more comprehensive three-dimensional spatial information. A groove 16 is provided on the upper surface of the shell 11, and a slide plate 18 is slidably connected to the inner wall of the groove 16. A protective brush ring 20 is fixedly connected to the upper surface of the slide plate 18. The size of the protective brush ring 20 is larger than the size of the lens, which can avoid bumping against the lens when the scanner body 13 rotates. Flexible bristles are arranged inside the protective brush ring 20, and a spring four 17 is fixedly connected to the lower surface of the slide plate 18. Two baffle bars 19 are fixedly connected to the upper surface of the slide plate 18. Two arc blocks 15 are fixedly connected to the surface of the scanner body 13.

[0047] The specific working method is: during a single measurement and when the scanner body 13 needs to be shifted, first hold the two cover plates 8 and slide them in opposite directions. During the sliding process, the two cover plates 8 will drive the two right-angle racks 301 to slide. The sliding of the two right-angle racks 301 can drive the two gears 303 to rotate. When the two gears 303 rotate, the multiple tooth plates 305 meshing with the two gears 303 will be lowered, thereby driving the mounting plate 10 and the scanner body 13 arranged above the mounting plate 10 to be synchronously lowered through the support plate 306. When the mounting plate 10 drives the scanner body 13 to descend into the protective box 2, the two right-angle racks 301 are disengaged from the two gears 303 respectively. At this time, the bottom ends of the two tooth plates 305 are in contact with the inner bottom wall of the protective box 2, and the two gears 303 are locked, so that the scanner body 13 can be stored and protected when shifting;

[0048] Next, the two cover plates 8 are pushed continuously. At this time, the telescopic connecting rod 1 517 and the telescopic connecting rod 2 518 are both retracted to the shortest point. When the two right-angle racks 301 continue to move, the telescopic connecting rod 1 517 drives the slotted moving plate 514 to move, thereby driving the movement of the air pipe 1 505. The telescopic connecting rod 2 518 drives the air pipe 2 520 to move. During the movement of the air pipe 1 505 inside the guide groove 503, the ball 1 508 set on the vertical rod 1 507 will reciprocate. The first ball 508 contacts the second ball 513, and then squeezes the first ball 508 to drive the vertical rod 1 507 to slide inside the circular groove 1 506, and then drives the piston 510 to slide, and extracts gas into the air pipe 1 505, until it slides to the inner wall of the circular groove 1 506. At this time, the first ball 508 is blocked and will squeeze the second ball 513 in the reverse direction to drive the sliding rod 511 to rise, thereby causing the separation between the first ball 508 and the second ball 513, and the piston 510 is driven by the return spring 5 The reset action of 21 will reset instantly, and the air inside the air pipe 1 505 will be ejected to clean the dust on the surface of the control display screen 12 set on the side of the scanner body 13. The two cover plates 8 continue to drive the two right-angle racks 301 to move toward each other, and can continue to push the air pipe 1 505 and the air pipe 2 520 to move. Under the action of the guide groove 503, the air pipe 1 505 moves to the lowest point of the guide groove 503 and is flush with the air pipe 2 520. At this time, the two suction cups 516 are respectively adsorbed on both sides of the shell 11. When the telescopic connecting rod 1 517 and the telescopic connecting rod 2 518 continue to drive the air pipe 1 505 and the air pipe 2 520 to move, the push blocks 509 set at the bottom ends of the vertical rod 1 507 and the vertical rod 2 523 will contact and squeeze the two stoppers 519 respectively, and pull the two pistons 510 to move again, so that negative pressure is generated inside the two suction cups 516 adsorbed on the side of the shell 11, thereby improving the adsorption effect and further improving the storage protection effect.

[0049] While performing adsorption protection, one of the right-angle racks 301 drives the adapter rod 411 to pass through the through hole and insert into the adapter hole 408 set on the wiping block 406. The set trapezoidal block 414 can limit the wiping block 406 and push the wiping block 406 to move. When the wiping block 406 is pushed and moved, it will pass through the lens surface of the scanner body 13, thereby wiping the lens of the scanner body 13 until the two cover plates 8 are in contact. When the buckle 9 is engaged, the magnetic block set on the wiping block 406 409 is adsorbed with the magnetic strip 14 provided on the mounting plate 10, and the wiping block 406 is adsorbed on the magnetic strip 14, so that when the cover plate 8 is opened and the adapter rod 411 is reset, the wiping block 406 is separated from the adapter block, and through the cooperation of the provided spring three 512 and the trapezoidal block 414, when the adapter rod 411 is reset, the trapezoidal block 414 is squeezed and compressed back into the rectangular groove 412, and no motion interference is caused, so that the used wiping block 406 is automatically unloaded until the cover plate 8 is opened to collect the used wiping block 406;

[0050] After cleaning the lens and the control display screen 12, and storing and protecting the scanner body 13, the scanner body 13 will rotate under the control of its internal rotating motor. During the rotation, the arc block 15 arranged on the surface will squeeze the baffle 19, driving the slide plate 18 to descend. When the lens is rotated downward, the arc block 15 will be separated from the baffle 19, and the slide plate 18 will drive the protective brush ring 20 to reset, thereby wrapping and protecting the lens, thereby improving the protection effect of the scanner body 13.
