[0026] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Reference Figures 1-4 The PCB board 3 is provided with a base 4 at the bottom end thereof; a cover body 5 is clamped on the top end of the base 4, and support columns 6 are connected to the top of the cover body 5 around the periphery thereof; rubber pads 7 are fixedly connected to the lower side of the surface of the support columns 6, and screws 8 are provided around the top end thereof; a plurality of telescopic rods 9 connected to the cover body 5 are provided at the bottom end of the housing 1, and springs 10 are provided on the surfaces of the telescopic rods 9. The rubber pads 7 at the top end of the PCB board 3 can play a certain buffering role thereon. When subjected to external force through the telescopic rods 9 and the springs 10, the cover body 5 can drive the PCB board 3 to move vertically, which can again play a role in reducing power buffering for the PCB board 3, thereby preventing the PCB board 3 from being damaged and affecting its normal use.

[0028] Furthermore, the screw 8 passes through the PCB board 3 and is threadedly connected to the inside of the support column 6, and the PCB board 3 contacts the top of the rubber pad 7, which makes it convenient to fix the PCB board 3 on the surface of the support column 6 and the top of the rubber pad 7 through the screw 8.

[0029] The first gear 13 and the second gear 13 are connected to the second gear 13 on the surface of the second gear 13, and the second gear 13 is connected to the screw 14 on the surface of the second gear 13. The screw 14 is connected to the inner part of the base 4 on both sides. The moving blocks 15 are connected to the two sides of the surface of the screw 14, and one side of the moving block 15 is connected to the positioning rod 16 movably connected to the baffle 2. The rotating rod 11 passes through the base 4 and is connected to a knob 17. By turning the knob 17, it can drive the rotating rod 11 and the first gear 12 to rotate, thereby driving the second gear 13 and the screw 14 to rotate, so that the moving block 15 on the surface of the screw 14 can drive the positioning rod 16 to move in a limited manner. The positioning rod 16 can be moved through the through slot to the two sides of the inner wall of the shell 1 to limit the base 4 and the PCB board 3. The threads on both sides of the screw 14 are set in opposite directions, so that when the screw 14 rotates, the moving blocks 15 on both sides of its surface move toward or away from each other at the same time.

[0030] Furthermore, the width of the base 4 is the same as the width of the baffle 2 , so that after the base 4 is placed into the inside of the baffle 2 , the positioning rods 16 on both sides of the base 4 can overlap with the through grooves on both sides of the baffle 2 .

[0031] Furthermore, through grooves are respectively provided on both sides of the baffle 2, and the inner diameter of the through grooves is the same as the diameter of the positioning rod 16, so that when the movable block 15 moves, the positioning rod 16 can pass through the through grooves and contact the inner wall of the shell 1, so as to limit the base 4.

[0032] Furthermore, the moving block 15 is slidably connected to the inner bottom end of the base 4, so that when the screw 14 rotates, the moving block 15 on its surface can drive the positioning rod 16 to move in a limited manner.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
