A part of the driving rod 11 extends into the inner side of the transmission outer ring 4, and the other part passes through the transmission outer ring 4 and extends outward to set a handle. The part extending into the inner side of the transmission outer ring 4 is meshed with the driving tooth block 12 to form a worm gear shape. By operating the handle of the driving rod 11, the rotating inner disk 5 can be rotated in the transmission outer ring 4, thereby adjusting the angle of the structure above the rotating inner disk 5;
[0026] A lifting bin 6 is fixedly arranged on the surface of the rotating inner disk 5, and a driving motor 8 is installed in the groove of the lifting bin 6. The output end of the driving motor 8 is connected to a positive and negative screw rod 7, and the positive and negative screw rod 7 is driven to rotate by the driving motor 8. On both sides of the positive and negative screw rod 7, there are oppositely distributed moving parts sleeved outside the positive and negative screw rod 7, and the moving parts are meshed with the positive and negative screw rod 7. With the rotation of the positive and negative screw rod 7, the two groups of moving parts move synchronously, and the tops of the two groups of moving blocks are connected to the bottom of the supporting top plate 9 through support rods, and the upper and lower ends of the support rods can be rotatable. By adjusting the angle between the two groups of support rods, the distance between the supporting top plate 9 and the lifting bin 6 can be changed, thereby realizing the adjustment of the height of the supporting top plate 9, and in order to improve the stability of the supporting top plate 9 during the up and down movement, Four groups of reinforcing links 13 are arranged on the side wall of the supporting top plate 9, the top of each group of reinforcing links 13 is connected to the supporting top plate 9, and the bottom is connected to the lifting bin 6, and the top of the reinforcing links 13 is connected to the supporting top plate 9 through a rotating shaft, and a sliding groove is provided on the surface of the lifting bin 6, and the reinforcing links 13 are slidably installed in the sliding groove, and the bottom of the reinforcing links 13 is connected to the reinforcing slide bar 14 through a rotating shaft, so that the reinforcing links 13 can be adjusted in angle with the reinforcing slide bar 14. Therefore, as the height of the supporting top plate 9 is adjusted, the reinforcing slide bar 14 will slide in the sliding groove, and the angle of the reinforcing links 13 will change at the same time. The four groups of reinforcing links 13 have the same structure, which can support the height adjustment of the supporting top plate 9 and improve stability.
[0027] The support top plate 9 is arranged above the rotating inner disk 5, and a clamping plate 10 is fixedly arranged on the top of the support top plate 9. A plurality of groups of jacks are provided on the surface of the clamping plate 10, and a clamping tube 15 is longitudinally inserted into the jacks. A locking mechanism is arranged between the clamping tube 15 and the clamping plate 10, and the locking mechanism comprises a locking adjustment rod 18, a locking slot 19, a locking plug 20, a top block portion 21 and a top block connecting rod 22. The locking slot 19 is arranged on the surface of the clamping tube 15, the locking plug 20 is installed in the clamping plate 10, the locking adjustment rod 18 is longitudinally installed in the clamping tube 15, the top block connecting rod 22 is connected to the bottom end of the locking adjustment rod 18, and the top block portion 21 is connected to the top block connecting rod 22. The bottom end of the clamping tube 15 is connected to the locking adjustment rod 18, and the groove of the locking slot 19 is provided with an opening that allows the top block 21 to pass through. The bottom of the clamping tube 15 is inserted into the insertion hole. As the clamping tube 15 descends, the bottom of the clamping tube 15 applies downward pressure on the inclined surface of the upper front end of the locking plug 20, so that the locking plug 20 is retracted into the slot in the clamping plate 10. A spring is arranged between the slot and the locking plug 20. When the clamping tube 15 continues to descend and falls to the bottom, the locking plug 20 is driven by the spring to snap into the groove of the locking slot 19, thereby fixing the position of the clamping tube 15. When the clamping tube 15 needs to be disengaged from the insertion hole, The locking adjustment rod 18 is pressed downward. The locking adjustment rod 18 is in an L-shaped structure. The horizontal axis of the locking adjustment rod 18 passes through the clamping tube 15 and leaks out of the clamping tube 15. An opening that allows the locking adjustment rod 18 to move longitudinally can be set in the clamping tube 15. As the locking adjustment rod 18 descends, the angle between the two sets of top block connecting rods 22 gradually increases, so that the two sets of top block parts 21 move in a direction away from each other. The two sets of top block parts 21 pass through the openings in the locking slot 19 and abut against the front end of the locking plug 20, thereby pushing the locking plug 20 out from the inside of the locking slot 19. In this way, the clamping tube 15 can be lifted upward, so that the clamping tube 15 can be quickly taken out, so that the clamping tube can be quickly inserted into different sockets according to needs. 15, and a support platform is arranged under the top block part 21, and the arrangement of the support platform enables the top block part 21 to move stably in the horizontal direction, and oppositely distributed spring bodies 17 are arranged in the clamping tube 15, and the two groups of spring bodies 17 are supported by brackets fixed on the inner wall of the clamping tube 15, and a clamping part 16 is installed on the top of the upper spring body 17. When the locking adjustment rod 18 is loosened, the spring body 17 in the lower half pulls the locking adjustment rod 18 to move upward, so that the locking adjustment rod 18 returns to its initial position, and the top spring body 17 can be longitudinally inserted into the top opening of the clamping tube 15. The insertion is that the clamping part 16 in the top opening of the clamping tube 15 is combined with the top of the spring body 17, and the bottom plate of the EMU can be limited by the clamping part 16, thereby completing the auxiliary disassembly and assembly work.
[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
