[0023] By the worker applying a downward force to the fixing blocks 8, the small clamping blocks 12 press the retaining blocks 11, the retaining blocks 11 press the springs 10, so that the small clamping blocks 12 are stuck at the bottom of the large clamping blocks 7, when it is needed to take down the protection box 2, only a downward force is applied to the protection box 2 again, so that the small clamping blocks 12 press the retaining blocks 11 opposite to the sliding blocks 6 again, the retaining blocks 11 press the springs 10, so that the small clamping blocks 12 are located at the bottom of the sliding blocks 6, drive the sliding blocks 6 to rise and attach to the bottom of the large clamping blocks 7, so that the protection box 2 is taken down, compared with the traditional device, by simple pressing and pulling actions, the protection box can be quickly installed and disassembled, without complex tools or additional operation steps, the working efficiency and the use convenience are greatly improved, when the internal equipment of the protection box needs to be maintained or replaced, the fixing can be quickly and conveniently released, the maintenance time and cost are reduced.

[0024] The top opposite surfaces of the protection box 2 are provided with sliding grooves 15, the left sides of the two sliding grooves 15 are provided with stretching grooves 16, the stretching grooves 16 are fixedly installed with stretching springs 17, the sliding grooves 15 are slidably installed with sliding rods 14, the sliding rods 14 are fixedly connected with the stretching springs 17, the opposite surfaces of the two sliding rods 14 are directly fixedly installed with protection covers 18.

[0025] The worker slides the protection cover 18 to the left, so that the protection cover 18 drives the sliding rods 14 to slide in the sliding grooves 15, since the sliding rods 14 are fixedly connected with the stretching springs 17, the stretching springs 17 are stretched in the stretching grooves 16, when stretched to a certain extent, the positioning receiver 19 is placed inside the protection box 2, the force applied to the protection cover 18 is released, so that the stretching springs 17 restore the elastic potential energy, the sliding rods 14 are pulled to the right, so that the sliding rods 14 slide in the sliding grooves 15, so that the protection cover 18 covers the top of the protection box 2.

[0026] By pulling the protective cover 18 to the left, the protective cover 18 drives the slide rod 14 to pull the extension spring 17, so that the protective cover 18 moves on the top of the protective box 2, so that the positioning receiver 19 is put into the inside of the protective box 2, and the force applied to the protective cover 18 is released again, so that the extension spring 17 drives the slide rod 14, and the slide rod 14 drives the protective cover 18 to cover the top of the protective box 2, thereby protecting the positioning receiver 19. Compared with the conventional installation, the elastic restoring force of the extension spring realizes the automatic closing of the protective cover. Once the positioning receiver is put into the protective box and the protective cover is released, the extension spring will quickly and smoothly pull the protective cover back to the original position to cover the top of the protective box, without the need for manual continuous operation, which is convenient and efficient, thereby prolonging the service life of the equipment.
