The protective plate 206 is subjected to pressure that is transmitted to the guide block 205, which moves the guide block 205, compressing the spring 204. The L-shaped plate 209 is subjected to pressure, compressing the spring 208 and the telescopic rod 207. T-slots 210 are provided on both sides of the U-shaped plate 203. The T-slots 210 are provided with T-plates 211 slidably connected to the interior of the T-slots 210, and one end of the two T-plates 211 is fixedly connected to the protective plate 206. The movement of the protective plate 206 drives the T-plates 211 to slide within the T-slots 210. The short arm end of the L-shaped plate 209 is fixedly connected to the U-shaped rod 212. The movement of the L-shaped plate 209 drives the U-shaped rod 212 to move. The U-shaped rod 212 is slidably connected to the exterior of the guide frame 213, and one side of the four guide frames 213 is fixedly connected to the U-shaped plate 203. The U-shaped rod 212 slides in the guide frame 213 .

[0035] Reference Figure 4 As shown, in this embodiment: the cleaning device 3 includes two fixed plates 31, and the side of the two fixed plates 31 close to each other is fixedly connected to the rubber frame 201, and a guide groove 32 is provided on one side of the fixed plate 31.

[0036] Working principle: Through the protective device 2, when it is necessary to prevent the tester from being damaged in the event of an accidental fall, the operator first installs the rubber frame 201 and the tester body 1. When the tester body 1 falls, the protective plate 206 or the L-shaped plate 209 first contacts the surface of the falling location. When the protective plate 206 is subjected to force, it is transmitted to the guide block 205. The guide block 205 moves to drive the spring 204 to contract. The elastic force generated by the spring 204 itself and the force it receives cancel each other out. When the L-shaped plate 209 is subjected to force, it is transmitted to the spring 208 and the telescopic rod 207. The elastic force generated by the contraction of the spring 208 and the telescopic rod 207 and the force it receives cancel each other out. Through the protective device 2, the problem of the traditional battery internal resistance tester having no external protective mechanism and often causing damage to the tester in the event of an accidental fall, which affects its service life, is solved.

[0037] By using the cleaning device 3, when the display screen of the tester needs to be cleaned, the operator first presses the movable plate 35 toward the tester body 1 so that the cleaning pad 36 contacts the display screen surface of the tester body 1, and then moves the U-shaped frame 34 so that the cleaning pad 36 performs a comprehensive cleaning on the display screen surface of the tester body 1. By using the cleaning device 3, the problem of the traditional battery internal resistance tester, in which the display screen is exposed to the air for a long time, is easily adhered to dust, and affects reading, and a cleaning cloth needs to be prepared separately to clean the display screen, which is inconvenient to operate, is solved.
