[0016] Compared with the prior art, the present invention has the following beneficial effects:

The sliding component is pulled out to make one end of the metal plate contact with the rubber strip of the clamping block, and the movable clamping block is slid so that the other end of the metal plate is pressed against the movable block.

[0018] The present invention achieves high rust removal efficiency through the coordination of structures such as a rotating assembly, a supporting assembly and a spray head. By starting a driving module, the driving module can drive the supporting assembly to rotate through the rotating assembly and the limiting plate.

[0019] The present invention achieves good rust removal effect by coordinating structures such as a support component, a limit component, and a nozzle. When the support component drives the metal plate to rotate downward through the limit component, the distance between the metal plate and the nozzle changes from far to near and then from near to far, so that the rust removal force of the nozzle sandblasting onto the surface of the metal plate gradually increases and then gradually decreases. Moreover, since the nozzles are distributed in a fan shape, the metal plate is vertically downward under the action of gravity, so that during the downward rotation of the metal plate, the angle of the nozzle sandblasting on the metal plate gradually changes, thereby achieving good rust removal effect on the metal plate by the device.

When the supporting component 5 drives the limit component 6 to rotate and move downward, the limit rod 602 can slide at one end of the arc groove 402, and the limit component 6 and the clamping block 7 can drive the metal plate 10 to move downward. The nozzle 8 at one end can be used to sandblast and remove rust on one side of the metal plate 10. When the supporting component 5 drives the metal plate 10 to rotate and move upward through the limit component 6, the limit rod 602 can slide to the other end of the arc groove 402, and the nozzle 8 at the other end can be used to sandblast and remove rust on the other side of the metal plate 10, so that the device can perform double-sided rust removal on multiple metal plates 10 at the same time, so that the rust removal efficiency of the device is high.
[0033] The movable block 604 is provided with pleated strips 611 on both sides, and the ends of the pleated strips 611 away from the movable block 604 are connected to the inner wall of the movable clamping block 601.

[0034] like Figure 1 and Figure 2 As shown, the sliding assembly 2 includes a support plate 201 and a limiting strip 202 arranged in an annular array on the support plate 201. A handle is arranged on the side of the support plate 201 away from the support tube 1. The outer peripheral surface of the limiting strip 202 is slidably connected to the support tube 1.
[0035] By pulling the handle of the sliding component 2, the rotating component 4, the supporting component 5, the limiting component 6, and the clamping block 7 structure can be pulled out of the supporting tube 1 through the supporting plate 201, so that the device is convenient for installing the metal plate 10.

[0037] The driving module 3 in this embodiment is configured as a driving motor, and the motor is a conventional driving device, which will not be described in detail here.
[0038] When the support assembly 5 drives the limit assembly 6 to rotate and move downward, the limit rod 602 can slide at one end of the arc groove 402, and the limit rod 602 can be limited by the arc groove 402, so that when the nozzle 8 is sandblasting and rust removal, the metal plate 10 can be prevented from swinging due to the thrust of sandblasting, thereby achieving a good rust removal effect on the metal plate 10. Similarly, when the support assembly 5 drives the metal plate 10 to rotate and move upward through the limit assembly 6, the metal plate 10 is acted upon by gravity, so that the limit rod 602 can slide to the other end of the arc groove 402. It is worth noting that when the limit assembly 6 drives the metal plate 10 to rotate to the top, the metal plate 10 can be quickly flipped over by the gravity of the metal plate 10, and the limit rod 602 can quickly slide to one end of the turntable 401.
[0039] like Figures 2 to 8 As shown, the top of the movable clamping block 601 is sleeved on the supporting assembly 5, both ends of the fixed strip 606 are fixedly connected to the movable clamping block 601, the outer side of the clamping block 608 is slidably connected to the movable clamping block 601, and the end of the clamping block 608 close to the card slot 502 is provided with an inclined surface, one end of the torsion block 609 is movably connected with the movable clamping block 601, and a magnet that is mutually attracted to the movable rod 607 is provided on the side of the torsion block 609 away from the fixed plate 610, both ends of the fixed plate 610 are fixedly connected to the movable clamping block 601, and the bottom end of the movable rod 607 does not contact the fixed strip 606, the limiting membrane 603 is made of elastic soft film material, the movable clamping block 601 and the clamping block 7 are both L-shaped structures, and rubber strips are provided on the movable block 604 and the clamping block 7, and a metal plate 10 that needs to be rust-removed is clamped between the limiting assembly 6 and the clamping block 7.
[0040] One end of the metal plate 10 is brought into contact with the rubber strip of the clamping block 7, and the movable clamping block 601 is slid so that the other end of the metal plate 10 is squeezed against the movable block 604, the spring 605 is compressed, and the movable rod 607 is rotated by gravity, and the movable rod 607 is adsorbed and limited by the magnetic force of the torsion block 609. The rotation of the movable rod 607 can push the block 608 upward, so that the block 608 can be inserted into the slot 502, so that the device is convenient for fixing and installing the metal plate 10. The narrow side of the metal plate 10 is clamped by the limiting component 6 and the clamping block 7, which can not only clamp the metal plate 10, but also will not hinder the rust removal on both sides of the metal plate 10, and by sliding the limiting component 6, the device can clamp metal plates 10 of different lengths.
[0041] The working principle and use process of the present invention:
[0042] First, the operator pulls out the sliding assembly 2, makes one end of the metal plate 10 contact with the rubber strip of the clamping block 7, slides the movable clamping block 601, so that the other end of the metal plate 10 is squeezed with the movable block 604, the spring 605 is compressed, the movable rod 607 is squeezed to rotate, and the movable rod 607 is adsorbed and limited by the magnetic force of the torsion block 609. The rotation of the movable rod 607 can push the clamping block 608 upward, so that the clamping block 608 can be clamped into the clamping slot 502. Repeat the operation to complete the installation and fixation of multiple groups of metal plates 10;
[0043] The sliding assembly 2 is pushed to move and completely close with the supporting tube 1. By starting the driving module 3, the driving module 3 can drive the supporting assembly 5 to rotate through the rotating assembly 4 and the limiting plate 9. When the supporting assembly 5 drives the limiting assembly 6 to rotate and move downward, the limiting rod 602 can slide at one end of the arc groove 402, and the limiting assembly 6 and the clamping block 7 can drive the metal plate 10 to move downward. The nozzle 8 at one end can be used to sandblast and remove rust on one side of the metal plate 10. When the supporting assembly 5 drives the metal plate 10 to rotate and move upward through the limiting assembly 6, the limiting rod 602 can slide to the other end of the arc groove 402, and the nozzle 8 at the other end can be used to sandblast and remove rust on the other side of the metal plate 10.
[0044] After rust removal is completed, pull the sliding assembly 2, and rotate the twist block 609 by twisting it, so that the twist block 609 can push the movable rod 607 to rotate, so that the movable rod 607 can pull the clamping block 608 to move downward and not engage with the clamping slot 502, and pull the movable clamping block 601 along the supporting assembly 5 toward the side away from the clamping block 7, and push the movable block 604 to reset through the spring 605, so that the metal plate 10 can be removed from between the limit assembly 6 and the clamping block 7, and the operation is completed.
