[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] This embodiment includes a base 1 and a wall panel 7. A mounting groove 2 is formed on the top wall of the base 1. A bidirectional lead screw 3 is rotatably connected between the left and right side walls of the mounting groove 2 via bearings. The left end of the bidirectional lead screw 3 passes through the left side wall of the mounting groove 2 via a bearing. A drive motor 6 is fixed to the left side wall of the base 1 with screws, and the output end of the drive motor 6 is connected to the left end of the bidirectional lead screw 3 via a coupling. Moving blocks 4, adapted to the mounting groove 2, are screwed onto the surfaces of both ends of the bidirectional lead screw 3. Two vertical plates 8 are respectively set on the top of the left and right sides of the base 1. An assembly assembly is connected between the vertical plates 8 and the moving blocks 4. A clamping groove 9 is formed in the middle of the vertical plate 8. When auxiliary positioning and fixing are required, the wall panel 7 can be placed in the clamping groove 9. Clamping mechanisms are provided on both the front and rear sides of the clamping groove 9. In use, to further protect the bidirectional lead screw 3, a lead screw protective cover can be installed on the bidirectional lead screw 3. A conventional bellows cover is sufficient, which is also commonly known as a bellows. The lead screw protective cover is a conventional lead screw protective component, and will not be described in detail here.

[0017] The assembly assembly described above can have various structural forms. Any assembly assembly that can fix the vertical plate 8 and the movable block 4 together is acceptable. The assembly assembly used in this embodiment includes a support block 5 welded to the top wall of the movable block 4, a protrusion 17 welded to the bottom wall of the vertical plate 8, and a groove 16 adapted to the protrusion 17 on the top wall of the support block 5. The purpose of this groove 16 is to allow the protrusion 17 to be movably inserted into the groove 16. The assembly assembly also includes a first through hole 18 opened on the surface of the protrusion 17 and a second through hole 19 opened on the front and rear side walls of the groove 16. The first through hole 18 and the second through hole 19 are aligned, and a positioning pin 20 is connected between the adjacent cavities of the first through hole 18 and the second through hole 19.

[0018] The aforementioned clamping mechanism includes cavities 13 located within the vertical plate 8 on both the front and rear sides of the clamping groove 9. Movable rods 11 are installed in the upper and lower inner cavities of the cavity 13. The inner and outer ends of the movable rods 11 movably penetrate the inner and outer walls of the cavity 13, respectively. The end closer to the clamping groove 9 is the inner end or inner side, and vice versa. A fixed rod 12 is fixedly connected to the outer ends of both movable rods 11. The purpose of the fixed rod 12 is to allow the movable rods 11 on both sides to move simultaneously. A retaining plate 10 is welded to the inner ends of both movable rods 11, and the retaining plate 10 is located within the groove of the clamping groove 9. The clamping mechanism also includes a pressing plate 14 disposed in the cavity 13. The upper and lower ends of the pressing plate 14 are respectively welded and sleeved on the surface of the movable rod 11 on the upper and lower sides. A spring 15 is disposed in the cavity 13 and sleeved on the surface of the movable rod 11. The spring 15 is located on the side of the pressing plate 14 away from the wall plate 7. The purpose is to allow the clamping plate 10 to apply a pressing force to the wall plate 7 placed in the clamping groove 9 under the elastic force of the spring 15.

[0019] In use, the drive motor 6 is started to rotate the bidirectional lead screw 3. Under the limiting guidance of the mounting groove 2, the moving blocks 4 on both sides can move closer or further apart according to the forward and reverse rotation of the drive motor 6. This, in turn, drives the vertical plates 8 on both sides to move closer or further apart through the assembly assembly. This allows wall panels 7 of different lengths to be placed between the clamping grooves 9 of the two vertical plates 8. The fixed rod 12 can drive the movable rod 11 to move. When the fixed rod 12 is pulled outward, it will cause the movable rod 11 to drive the abutment plate 10 to move outward, thereby changing the distance between the two abutment plates 10 in the same clamping groove 9, so that wall panels of different thicknesses can be placed. 7. Furthermore, when the movable rod 11 moves outward, it causes the pressing plate 14 to press the spring 15. This allows the clamping plate 10 to automatically clamp and fix the wall panel 7 under the action of the spring 15 after the fixing rod 12 is released. This is very convenient and allows the construction connection device to be applied to wall panels 7 of different lengths and thicknesses, greatly improving its practicality. When the vertical plate 8 needs to be removed, simply pull out the positioning pin 20 from the first through hole 18 and the second through hole 19. Then, the protrusion 17 can be removed from the groove 16, and the vertical plate 8 can be removed from the base 1. This facilitates the transportation and carrying of the construction connection device and reduces the floor space occupied.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
