[0028] The assembly component 4 includes a first clamping plate 8 and a second clamping plate 9 that are arranged relatively to each other. The inner sides of the bottom ends of the first clamping plate 8 and the second clamping plate 9 are respectively fixedly connected with a first limit head 10 and a second limit head 11. A guide groove 16 is provided on the surface of the first clamping plate 8. The top ends of the first clamping plate 8 and the second clamping plate 9 are respectively fixedly connected with a docking base 14 and a top rod 15. The docking base 14 is also movably connected to the adjusting screw 13. The inner top surface of the second clamping plate 9 is fixedly connected with a spring 18.

[0029] In the embodiment of the utility model, the first mounting portion 5 and the second mounting portion 6 are respectively located on the front sides of the shell 2, and both are rectangular concave settings. The guide head 17 is longitudinally protruding and is movably embedded in the guide groove 16. The first mounting portion 5 and the second mounting portion 6 are used to facilitate the flipping and adjustment of the corresponding first clamping plates 8 and second clamping plates 9, and the guide head 17 is used to limit and fix the first clamping plate 8.

[0030] The support base 7 is set as a rectangular base, and the adjusting screw 13 vertically passes through the mounting top plate 1 and is embedded in the shell 2, and is threadedly connected to the support base 7. The bottom platform 12 is set as an "L"-shaped hard rubber platform as a whole, and one side of its bottom is set at a downward angle, and the surface of the bottom platform 12 is provided with anti-slip stripes. The threaded support base 7 and the adjusting screw 13 are used to control the lifting and lowering adjustment of the docking base 14 inside the shell 2, and the bottom platform 12 is used to assist in fixing the device body 3.

[0031] The first clamping plate 8 and the second clamping plate 9 are both arranged vertically in an "L" shape, and the guide groove 16 is also opened in an "L" shape on the middle angle surface of the first clamping plate 8. The top of the first clamping plate 8 is movably connected to the docking base 14 through a pin shaft, and the middle angle position of the second clamping plate 9 is movably connected to the angle position of the bottom side of the second mounting portion 6 through a pin shaft. The bottom end of the first clamping plate 8 is arranged in an inward horizontal angle, and the first limit head 10 is vertically connected to the angle position of the bottom end of the first clamping plate 8. The first limit head 10 and the second limit head 11 are both set as rubber heads, and the top rod 1 5 is vertically arranged and located below the docking base 14, and the spring 18 is configured as a metal compression spring, the bottom end of which is fixedly connected to the base 12.
