[0051] A specific application of this embodiment is:

[0052] When the entire device is not clamping and lifting the external hanging plate, the L-shaped supporting and placing plates 24 on both sides are in positions far away from each other, the electric telescopic rod 23 is in the longest position, and the pressing plate 34 is at the uppermost side of the movable groove 3. When the external hanging plate needs to be lifted, the staff can place the external hanging plate between the L-shaped supporting and placing plate 24 and the pressing plate 34, and start the motor 14 and the electric telescopic rod 23. The start of the motor 14 can make the double-threaded rod 13 rotate, so that the limit rings 2 on both sides can drive the limit rod 21 and the connecting plate 22 to approach each other, thereby driving the L-shaped supporting and placing plates 24 on both sides to approach each other, thereby achieving the clamping of the external hanging plate. By starting the electric telescopic rod 23, the height of the L-shaped supporting and placing plate 24 can be changed. When the L-shaped supporting and placing plate 24 moves upward, the stretching rod 33 can drive the movable plate 31 and the pressing plate 34 to move in the opposite direction relative to the L-shaped supporting and placing plate 24, so that the external hanging plate can be lifted from the upper side. The clamping is performed to enhance the clamping effect of the device and prevent shaking during lifting, thereby enhancing the safety of the device. Secondly, when the external hanging plate is placed on the L-shaped supporting placement plate 24, the extrusion effect of the external hanging plate can be used to make the extrusion column 42 squeeze the elliptical extrusion bag 41 downward. Under the extrusion effect, the elliptical extrusion bag 41 can be deformed. The deformation effect of the elliptical extrusion bag 41 can be used to push the movable guide rod 43 to move laterally. The lateral movement of the movable guide rod 43 can drive the piston plate 44 to move laterally inside the L-shaped supporting placement plate 24, thereby achieving the purpose of squeezing the internal gas. Under the squeezing effect, the gas can pass through the jet hole 5 and then act on the contact portion between the outer wall of the bottom side of the external hanging plate and the L-shaped supporting placement plate 24. Therefore, the pushing effect of the airflow can be used to clean the outer wall of the bottom side of the external hanging plate, thereby preventing impurities from existing in the contact portion between the outer wall of the bottom side of the external hanging plate and the L-shaped supporting placement plate 24 and affecting the clamping effect.

[0053] Under the squeezing effect of the piston plate 44, part of the gas can enter the interior of the air guide tube 6. Under the action of the gas driving force, the air pressure ball 61 can drive the moving cross bar 62 to move laterally. The lateral movement of the moving cross bar 62 can drive the support reinforcement plate 7 to move laterally on the bottom side of the external hanging plate, thereby increasing the limiting area of ​​the device on the bottom side of the external hanging plate, thereby enhancing the clamping effect of the device. Under the effect of the lateral movement of the support reinforcement plate 7, the semicircular rubber ball 8 can pull the rubber pull rod 81 to move, and the movement of the rubber pull rod 81 can drive the rubber cleaning rod 82 to move, and can drive the cleaning brush 83 to move along the bottom outer wall of the external hanging plate. Therefore, the moving effect can be utilized to enhance the cleaning effect of the device on the bottom outer wall of the external hanging plate, thereby enhancing the clamping effect of the device. After the extrusion jet is completed, the return spring 71 can pull the rubber cleaning rod 82 to reset.

[0054] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
