The front and rear sides of the movable frame 2 are respectively provided with an inverted L-shaped connecting block 4 located in the corresponding side clearance groove, and the outer wall of the connecting block 4 is fixedly connected with a lifting rod 5 located in the corresponding side lifting groove 3, and the front and rear sides of the support plate 1 are respectively provided with sliding grooves, and the left and right sides of the sliding groove are respectively provided with driving grooves, two connecting rods 7 are hinged on the lower side of the driving assembly, and the other end of the connecting rod 7 is hinged with a slider 8 located in the sliding groove, and an inverted L-shaped positioning block 9 is provided on the upper side of the slider 8, and the left and right sides of the positioning block 9 are respectively fixedly connected with a driving rod 10 located in the driving groove 6, and a rotatable sleeve 11 coaxial with the face gear 16 is provided in the middle, and a liftable positioning column 12 is provided in the sleeve 11.

[0020] like Figures 1 to 6 As shown, a driving assembly, a mobile frame 2, a yielding groove, a lifting groove 3, a connecting block 4 and a lifting rod 5 are provided. The driving assembly can be used to drive the mobile frame 2 to move, and then the lifting groove 3 and the lifting rod 5 are used to drive the connecting block 4 to push the frame 23 to fix and position in the left and right directions or to release the fixation and positioning. At the same time, when not in use, the connecting block 4 will be retracted into the bracket to make the top of the bracket flat and easy to place. The face gear 16, the connecting rod 7, the sliding groove, the driving groove 6, the sliding block 8 and the driving rod 10 are provided to position and fix the frame 23 in the front and rear directions, and then the frame 23 can be fixed in the center in all directions, which is convenient for assembly and connection. The sleeve 11 and the positioning column 12 are provided so that when the center positioning is performed, the positioning column 12 is raised to further fix it, and at the same time, the connection stability between the frame 23 and the support plate 1 is improved, thereby Figure 5It can be seen that the connecting block 4 and the movable frame 2 are connected by a slide groove and a slide rail, which can ensure that the connecting block 4 will not be skewed during the lifting process, and at the same time improve the connection stability. At the same time, the positioning block 9 and the slider 8 are connected in the same way, and the bidirectional screw 14 has self-locking properties, which can prevent the bidirectional screw 14 from rotating at will, ensuring the stability of the connection and the accuracy of the center positioning.

[0021] The driving assembly includes a driving motor 13, the output end of the driving motor 13 is fixedly connected to a bidirectional lead screw 14, the bidirectional lead screw 14 is rotatably connected to the support plate 1, the left and right sides of the bidirectional lead screw 14 are respectively threadedly connected to the moving frame 2 on the corresponding side, and the middle part of the bidirectional lead screw is fixedly connected to a spur gear 15, which can mesh with the face gear 16.

[0022] like Figure 2 As shown, a driving motor 13, a bidirectional lead screw 14 and a spur gear 15 are provided. The driving motor 13 can be used to drive the connecting blocks 4 on both sides to move via the bidirectional lead screw 14, and at the same time, the spur gear 15 and the face gear 16 can be used to drive the positioning blocks 9 on the front and rear sides to move, so as to facilitate all-round positioning and connection and fixation.

[0023] An L-shaped connecting rod 17 is connected to the upper end of the face gear 16, and the connecting rod 17 is fixedly connected to the sleeve 11. Grooves 18 are respectively provided on the front and rear sides of the positioning column 12, and sliding pins 19 are respectively provided on the front and rear sides of the sleeve 11 and are located in the corresponding side grooves 18.

[0024] like Figures 2 to 6 As shown, the connecting rod 17, the groove 18 and the sliding pin 19 are arranged so that when the face gear 16 rotates, the sleeve 11 is driven to rotate via the connecting rod 17, and then the positioning column 12 is driven to rise through the rotation of the sleeve 11 and the action of the groove 18 and the sliding pin 19, and inserted into the frame 23 for secondary positioning.

[0025] A fixing plate 20 is fixedly connected to the middle of the support plate 1 , and a prism 21 is fixedly connected to the upper end of the fixing plate 20 . The prism 21 is sleeved with the positioning column 12 .

[0026] like Figure 6 As shown, the provision of the fixing plate 20 and the prism 21 can prevent the positioning column 12 from rotating with the sleeve 11, thereby ensuring that the positioning column 12 can be normally lifted and lowered when the sleeve 11 rotates.

[0027] The connecting block 4 and the positioning block 9 are both provided with positioning holes 22, a frame 23 is provided at the upper end of the support plate 1, and a plurality of screw holes 24 corresponding to the positioning holes 22 are provided on the lower side of the frame 23, and the screw holes 24 can be coaxial with the corresponding side positioning holes 22, and a through hole 25 is provided in the middle of the frame 23, and the positioning column 12 can be inserted into the through hole 25, and the diameter of the lower side of the through hole 25 is slightly larger than the diameter of the positioning column 12.

[0028] like Figures 1 to 5 As shown, the positioning hole 22 and the screw hole 24 can be set to perform secondary fixation with screws after the initial connection and positioning to ensure stable connection. The through hole 25 can facilitate the positioning column 12 to be inserted into the through hole 25. The lower side of the through hole 25 is chamfered to facilitate the positioning column 12 to be normally inserted therein.

[0029] The support plate 1 is provided with two rotating wheels 26 facing each other front and back respectively on the left and right sides.

[0030] like Figure 1 As shown, a rotating wheel 26 is provided to facilitate movement of the whole when in use.

[0031] When the utility model is in use, the frame 23 is placed near the center of the support plate 1, and then the driving motor 13 can be started. The driving motor 13 drives the mobile frames 2 on the left and right sides to move relatively through the bidirectional lead screw 14, and then drives the connecting block 4 to move toward the center of the support plate 1 in the clearance groove. The lifting groove 3 and the lifting rod 5 can be used to make the connecting block 4 quickly extend out of the support plate 1 during movement. At the same time, the bidirectional lead screw 14 drives the face gear 16 to rotate through the spur gear 15. The rotation of the face gear 16 drives the positioning blocks 9 on the front and rear sides to extend out of the support plate 1 and move to the center of the support plate 1 through the connecting rod 7. At the same time, the sleeve 11 is driven to rotate through the connecting rod 17, and the sliding pin 19 moves in the groove 18;

[0032] When the connecting block 4 and the positioning block 9 contact the frame 23, the frame 23 is driven to be centrally positioned. When the frame 23 gradually moves toward the center, the positioning column 12 is pushed out from the support plate 1 and inserted into the through hole 25, and then further connected and positioned to ensure that the frame 23 is completely in the center of the support plate 1. Subsequently, a screw is inserted into the positioning hole 22 and screwed into the screw hole 24 corresponding to the positioning hole 22 to complete the positioning and connection fixation of the frame 23.

[0033] In the present invention, the driving motor 13 is of the prior art and will not be described in detail here.

[0034] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
