Firstly, the fixing section 31 is square, and one end of the fixing section is fixedly connected with the spliced screen unit 1, so that the spliced screen unit 1 is ensured to be stably attached to the connecting piece 3. The other end is connected to the sliding section 32 by a rotation shaft 34, which allows the fixed section 31 to perform a rotational movement about the rotation shaft 34.

One end of the sliding section 32 is connected to the fixed section 31 and is rotatably connected by a rotation shaft 34. The other end is provided with a guide block, and referring to fig. 4, the support column 2 is provided with a guide groove 21, and the guide block is slidably connected with the guide groove 21 on the support column 2, so that the sliding section 32 is allowed to move in the guide groove 21 on the support column 2, and the longitudinal splicing of the spliced screen unit 1 is realized. Guide grooves 21 are formed in two sides of the support column 2 along the bus direction, and can be connected with the spliced screen unit 1 to realize transverse splicing of the spliced screen unit 1.

At the top of the support column 2, a constant force coil spring 23 is mounted. The free end of this constant force coil spring 23 may be connected to the connector 3.

Secondly, the design of the positioning groove 11 and the positioning piece 12 can effectively prevent the adjacent spliced screen units 1 from unnecessarily moving or shifting in the use process, thereby being beneficial to keeping the overall appearance and performance of the spliced screen and avoiding irregular gaps or dislocation.

In addition, the design of the positioning groove 11 and the positioning piece 12 greatly simplifies the installation process of the spliced screen, and an installer only needs to easily slide the positioning piece 12 of the spliced screen unit 1 into the positioning groove 11 without complex positioning adjustment or using an additional supporting device.

The upper and lower sides of the spliced screen units 1 are equipped with special buffer glue layers 13, and when the spliced screen units 1 collide or contact, the buffer glue layers 13 play a role in absorbing impact force, so that physical damage between the spliced screen units 1 is effectively prevented.

In addition, the buffer adhesive layer 13 has a function of reducing external shock or the influence of vibration on the spliced screen. They can effectively slow down the speed and force of external impact transmitted to the spliced screen unit 1, thereby ensuring that the spliced screen unit 1 remains stable. The method is not only beneficial to improving the stability of the image, but also improves the visual effect of the whole spliced screen system, and brings clearer and smoother viewing experience for users.
