[0057] The transmission assembly comprises:

[0058] A first support plate 12 and a second support plate 13 fixedly mounted in the accommodating cavity of the support box 1;

[0059] A third rotating shaft 30, wherein the third rotating shaft 30 is rotatably mounted on the second supporting plate 13, and one end of the third rotating shaft 30 is connected to the bidirectional threaded rod 24 via a second gear set 25, and a driven block 32 is fixedly mounted on the other end of the third rotating shaft 30, and a plurality of circular through holes are provided on the driven block 32; wherein the second gear set 25 is two sets of bevel gears meshing with each other;

[0065] In one embodiment of the present invention, see Figure 1-Figure 7 , the control component comprises:

[0066] A driving frame 10, wherein the driving frame 10 is slidably mounted in the accommodating cavity of the supporting box 1, and the driving frame 10 is fixedly connected to the driven frame 26;

[0067] and a driving block 4 rotatably mounted on the top plate 3, wherein a one-way threaded rod 14 threadably connected to the driving frame 10 is fixedly mounted on the driving block 4;

[0068] The driving assembly includes a first rotating shaft 5 and a first gear set 11. The first rotating shaft 5 is rotatably mounted on the bottom plate 6 and is located at the center of the supporting box 1. The first rotating shaft 5 is connected to the second rotating shaft 27 via the first gear set 11. The first gear set 11 is two sets of bevel gears meshing with each other.

[0069] The tops of the driving block 4 and the first rotating shaft 5 are both provided with hexagonal grooves, which are convenient for use with a hexagonal wrench.

[0070] In this embodiment, the driving block 4 is used to facilitate the rotation of the one-way threaded rod 14. The rotating one-way threaded rod 14 will drive the driving frame 10 to move in the length direction of the one-way threaded rod 14, thereby driving the driven frame 26 to follow the movement of the one-way threaded rod 14, thereby realizing the switching of the working positions of the third magnet 31 and the second magnet 29; through the coordinated arrangement of the first rotating shaft 5 and the first gear set 11, it is convenient to drive the second rotating shaft 27 to rotate.

[0071] In summary, the working principle of the present invention is as follows: when in use, the support box 1 is fixed to the construction area by using the bottom plate 6, and then the connecting frame 7 on the wall panel is inserted into the limiting hole 2, so that the connecting frame 7 can enter one of the groups of accommodating chambers in the support box 1, and the working state of the transmission component is controlled by the control component, so that the locking component in the group of accommodating chambers can be driven to work by the driving component, and the working locking component will fix the connecting frame 7 to fix the wall panel to the side of the support box 1, and repeat the above steps to achieve the connection and fixation between the support box 1 and multiple groups of wall panels, which is convenient for installation and can improve work efficiency; specifically, when the control component drives the driven frame 26 to move downward so that the third magnet 31 is opposite to the first magnet 28, the third magnet 31 will push the first magnet 28 to move on the second rotating shaft 27, so that the transmission rod 33 can be inserted into the circular through hole on the driven block 32, so that the third rotating shaft 30 can rotate with the second rotating shaft 27, and when the control component drives the driven frame 26 to move upward so that the second magnet 29 is opposite to the first magnet 28, the second The magnet 29 can generate suction force on the first magnet 28, so that the first magnet 28 drives the transmission rod 33 to separate from the driven block 32. At this time, the third rotating shaft 30 will not rotate with the second rotating shaft 27, thereby realizing the driving of the locking components in different accommodating cavities to work respectively; the rotating third rotating shaft 30 can drive the two-way threaded rod 24 to rotate by cooperating with the second gear set 25, so that the two-way threaded rod 24 drives the two sets of sliders 23 to move to both sides, so that the locking block 22 is inserted into the fixing hole 8, thereby realizing the fixation of the connecting frame 7. When the slider 23 is moving, the stand 21 will drive the guide wheel 20 to follow the slider 23. When the guide wheel 20 slides out from the hypotenuse of the trapezoidal block 18, the spring 16 will push the lifting plate 17 to move toward the side of the slider 23, so that the locking plate 19 can be inserted into the fixing groove 9, thereby further fixing the connecting frame 7 and improving the fixing effect. When the slider 23 is reset, the guide wheel 20 can use the trapezoidal block 18 to push the lifting plate 17 to compress the spring 16 through the cooperation with the stand 21, so that the locking plate 19 is separated from the fixing groove 9.
