The second indication information includes the display screen 32 showing no pass and/or the indicator light showing red. The indicating unit 30 may only include a display screen 32 or an indicator light, or may include a display screen 32 and an indicator light. The first indication information may be that the display screen 32 displays Pass and the indicator light displays green, or the display screen 32 displays Pass and the indicator light displays green. The second indication information may be that the display screen 32 displays NG. The indicator light shows red, or the display screen 32 shows NG and the indicator light shows red. The display screen 32 may be a touch display screen 32.

In an example, the default range of the good product of the insertion force is 4-6N or less, preferably 5N or less. In other words, if the insertion force is less than or equal to 5N, the battery 220 is a good product, and if the insertion force is greater than 5N, the battery 220 is not a good product. The preset range of good product withdrawing force is 9-11N or less, and preferably 10N or less. In other words, when the pull-out force is 10N or less, the battery 220 is a good product, and when the pull-out force is greater than 10N, the battery 220 is a non-good product.

In this way, the controller controls the number of times the drive mechanism 20 inserts the battery 220 into the body 210 or pulls out the body 210 according to the set number of insertion and removal times, so as to obtain multiple sets of insertion and removal force data of the same battery 220, and then according to the multiple sets of The insertion force data calculates the average insertion force and average extraction force, making the measurement results more accurate. In this embodiment, the input component 40 includes a touch screen, and the user can set the number of times of plugging and unplugging the battery 220 on the touch screen. Of course, the input component 40 may also include pressing keys, knobs, and sliding keys. The user can set the number of insertion and removal of the battery 220 by pressing the keys, knobs, and sliding keys. The specific setting method is not limited here. The touch screen may be the touch display 32.

The controller is used to control the driving mechanism 20 to stop running according to the stop signal from the input assembly 40. In this way, in the event of an emergency (such as pinching a user's finger), the driving mechanism 20 can be controlled to stop operation by inputting a stop signal. In this embodiment, the input component 40 includes an emergency stop button, and the user can stop the driving mechanism 20 by pressing the emergency stop button.

In some embodiments, the measuring device 100 includes a detachment part (not shown). The battery 220 is provided with a detachment button. When the battery 220 is inserted into the body 210, the detachment part is used to trigger the detachment button so that the battery 220 can be removed from the body 210.
