Specifically, after the spring 20 is fixed inside the hole 19, the spring 20 is fixed in the hole 19, and after the other end of the spring 20 is fixed to the movable plate 18, the movable plate 18 is fixed. When the multimeter falls, the spring 20 is moved downward in cooperation with the movable plate 18, thereby cooperating to play a good buffering effect. After the impact force is pressed onto the support plate 10, the shaft 1 16 and the inclined plate 15 are rotated, so that the shaft 1 16 rotates through the inclined plate 15 in cooperation with the shaft 2 17, thereby playing a certain buffering effect.

Please refer to Figures 4 to 5. The cleaning mechanism 2 includes a rotating shaft 204, one side of the outer wall of the rotating shaft 204 is fixedly connected to the right side of the top of the watch case 1, a transparent plate 201 is rotatably connected between the adjacent rotating shafts 204, and a sliding column 209 is fixedly connected to the middle of the left and right sides of the transparent plate 201. The front side of the top inner part of the watch case 1 is rotatably connected to an elongated plate 205, and an elongated hole 207 is provided on the inner side of the elongated plate 205. The outer wall of the elongated hole 207 is slidably connected to the outer wall of the sliding column 209. The top of the elongated plate 205 is provided with a clamping hole 202, and a buckle 206 is provided inside the clamping hole 202.

Finally, the control button 3 is fixed on the watch case 1, so that all electrically connected devices on the equipment can be switched on and off through the control button 3, thereby facilitating the operator to use the equipment.

Working principle: Usually, when using the multimeter, firstly, the hole 19 is fixed with a spring 20, so as to be fixed with the moving plate 18. When the multimeter falls, the moving plate 18 is used to press the spring 20 inward to achieve a buffering effect. Then, when the impact force is pressed onto the support plate 10, the rotating shaft 16 is used to rotate on the rotating shaft 2 17 through the inclined plate 15, so as to press the support plate 10 downward and press the rubber block 7 to achieve a certain buffering effect, thereby achieving effective protection of the housing of the multimeter and playing a role in the falling process. The buffering effect can be achieved, which can effectively avoid damage to the multimeter and improve the practicality of the equipment. Subsequently, the handle 5 is used to cooperate with the transparent plate 201 and the rotating shaft 204 to pull upward, so that the rotatably connected elongated plate 205 cooperates with the elongated hole 207 and the outer wall of the sliding column 209 to slide, so that the transparent plate 201 is in an inclined state, and then the scraper 208 is moved along the elongated groove 203 to clean the dust on the transparent plate 201, thereby solving the problem of being able to clean the dust generated on the display screen, allowing the operator to accurately see the numbers and improving the utilization rate of the equipment.
