The right side of the rear side of the lower surface of the T-shaped card slot 11 is electrically connected with a vibration trigger spring 14. The function of the vibration trigger spring 14 is to generate mechanical swing when subjected to external vibration, and the swing triggers the trigger contact point of the PCB substrate 1, the current is conducted, and the IC receives the trigger conduction signal and starts to work. The front side of the bottom of the pressing ring 21 is fixedly connected with a metal blocking piece 24, and the inner surface of the pressing ring 21 is fixedly connected with a metal elastic piece 25;

[0026] When installing the battery positive electrode elastic piece 2, only need to snap the reverse T-shaped clamping plate 23 into the inside of the T-shaped card slot 11, then the battery positive electrode elastic piece 2 can be fixed. After that, snap the button battery 3 between the positioning side plates 22.

At the same time, the positioning side plates 22 can be restricted by the button battery 3, so that the reverse T-shaped clamping plate 23 cannot break away from the T-shaped card slot 11, and the button battery 3 can be effectively installed and fixed.

[0027] As Figure 3 As shown in the figure, the present utility model provides a new type of button battery installation structure. Sliding grooves 1 are opened on both the front and rear sides of the transverse inner surface of the T-shaped card slot 11. Arc-shaped stoppers 111 are slidably connected in the sliding grooves 1. T-shaped push plates 112 are fixedly connected to the opposite surfaces of the two arc-shaped stoppers 111. Sliding grooves 2 are opened on both the front and rear sides inside the PCB substrate 1.

[0028] When the reverse T-shaped card plate 23 is inserted into the T-shaped card slot 11, under the pushing of the first spring 113, the T-shaped push plate 112 can push the arc-shaped stopper 111, so that the arc-shaped stopper 111 can block on the inner surface of the T-shaped card slot 11, thereby restricting the position of the reverse T-shaped card plate 23 and making the installation effect of the battery positive electrode elastic sheet 2 better.

[0029] As Figure 5 shown, the present utility model provides a new type of button battery installation structure. A sliding slot is opened at the bottom end of the positioning side plate 22. The top end of the reverse T-shaped card plate 23 penetrates into the inside of the sliding slot. Sliding top plates 231 are fixedly connected to the front and rear sides of the top end of the metal elastic sheet 25. A guiding sliding column 232 that penetrates up and down is slidably connected to the middle of the sliding top plate 231. The two guiding sliding columns 232 are respectively fixedly connected to the front and rear sides of the inner wall of the sliding slot.

The position of the button battery 3 can be restricted by the metal baffle 24, and the button battery 3 can be pressed by the metal elastic sheet 25. Under the pushing of the second spring 233, the sliding top plate 231 can pull the reverse T-shaped card plate 23, so that the pressure ring 21 can be tightened by the positioning side plate 22, making the pressing force of the metal elastic sheet 25 on the button battery 3 greater. At the same time, the positioning side plates 22 can be restricted by the button battery 3, so that the reverse T-shaped card plate 23 cannot be separated from the T-shaped card slot 11, effectively installing and fixing the button battery 3 and improving the fixing effect.
