The first U-shaped frame is fixedly connected to the side wall of the installation box, and the second U-shaped frame is connected to the first U-shaped frame by an elastic component. By pulling the second U-shaped frame in a direction away from the first U-shaped frame by hand, the enclosed area of ​​the first U-shaped frame and the second U-shaped frame can be increased, making it convenient to put the installation frame into the first U-shaped frame. After releasing the hand, the second U-shaped frame moves toward the first U-shaped frame under the force of the elastic component restoring the deformation, so that the installation frame is limited in the inner frame of the limiting frame.

[0013] Preferably, the elastic component includes a T-shaped pressure rod and a support ring, wherein the T-shaped pressure rod is arranged at the end of the second U-shaped frame, and the support ring is arranged in a cavity at the end of the first U-shaped frame, wherein the T-shaped pressure rod extends into the support ring, and the support ring is provided with a reset spring sleeved on the T-shaped pressure rod, and the support ring is also provided with a through groove for the T-shaped pressure rod to penetrate. By pulling the second U-shaped frame to move the T-shaped pressure rod in the through groove and squeezing the reset spring sleeved on the support ring at the same time, the enclosed area of ​​the first U-shaped frame and the second U-shaped frame can be increased, and after the mounting frame is snapped into place, the second U-shaped frame returns to its original position under the action of the reset spring restoring the deformation force, thereby achieving the purpose of limiting the mounting frame to the inner frame of the limiting frame.

By pulling the second U-shaped frame to move away from the first U-shaped frame by hand, the enclosed area of the first U-shaped frame and the second U-shaped frame can be increased, facilitating the mounting frame to be placed into the first U-shaped frame. After letting go, the second U-shaped frame moves towards the first U-shaped frame under the action of the elastic member restoring its deformation, restricting the mounting frame within the inner frame of the limiting frame.

[0020] 2. By pulling the second U-shaped frame to move the T-shaped pressure rod in the through groove and simultaneously squeezing the return spring sleeved on the support ring, the enclosed area of the first U-shaped frame and the second U-shaped frame can be increased. After the mounting frame is snapped in place, the second U-shaped frame returns to its original position under the action of the return spring restoring its deformation force, thereby achieving the purpose of restricting the mounting frame within the inner frame of the limiting frame.
