[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] like Figure 1 to Figure 3As shown, a handheld battery internal resistance tester includes a tester body 1, on which a display screen 2 is fixedly installed, a wiring slot 4 is opened on the tester body 1, and a test probe 3 is connected to the wiring slot 4. A first positioning mechanism 5 is fixedly installed at the middle position of the bottom of the tester body 1, and the first positioning mechanism 5 includes an isolation pad 501, a positioning frame 502, a connecting slot 503, a docking through hole 504, a docking screw 505 and a strong magnet 506. A second positioning mechanism 6 is provided at the edge of the tester body 1, and the second positioning mechanism 6 includes a connecting base 601, a connecting through hole 602, a connecting screw 603, a connecting leg 604 and a rubber suction cup 605. The test probe 3 is connected to the tester body 1 through the wiring slot 4.

[0019] A first positioning mechanism 5 is fixedly installed at the middle position at the bottom of the tester main body 1, and the first positioning mechanism 5 includes an isolation pad 501, a positioning frame 502, a connecting groove 503, a docking through hole 504, a docking screw 505 and a strong magnet 506. The positioning frame 502 is installed at the bottom of the tester main body 1, and a connecting groove 503 is opened on the positioning frame 502, and a strong magnet 506 is arranged in the connecting groove 503. Docking through holes 504 are opened at the four corners of the positioning frame 502, and docking screws 505 are arranged in the docking through holes 504. An isolation pad 501 is arranged on the upper end of the positioning frame 502, and a second positioning mechanism 6 is arranged at the edge of the tester main body 1. The second positioning mechanism 6 includes a connecting base 601, a connecting through hole 602, a connecting screw 603, a connecting leg 604 and a rubber suction cup 605. The connecting base 601 is connected to the tester main body 1. At the bottom of the tester body 1, a connecting through hole 602 is opened at the edge of the connecting base 601, and a connecting screw 603 is arranged in the connecting through hole 602. A rubber suction cup 605 is arranged at the bottom of the connecting base 601, and a connecting leg 604 is arranged on the rubber suction cup 605. When in use, the strong magnet 506 can be adsorbed on the iron object or structure on one side of the battery, so as to fix the tester body 1 on one side of the battery. At the same time, when the strong magnet 506 has no adsorbent, the rubber suction cup 605 can be connected to the surface of the battery. After the rubber suction cup 605 is connected to the surface of the battery, the tester body 1 can be pressed to discharge the air in the rubber suction cup 605. After the air in the rubber suction cup 605 is discharged, it will be adsorbed on the surface of the battery, so as to fix the tester body 1 on the battery, which is convenient for the testing staff to observe the display screen 2.

[0020] It should be noted that the utility model is a handheld battery internal resistance tester. When it is actually used, firstly, the strong magnet 506 is adsorbed on the iron object or structure on one side of the battery. Since the docking screw 505 is connected to the positioning frame 502 through the docking through hole 504, the positioning frame 502 is fixed to the bottom of the tester body 1 through the docking screw 505, and the strong magnet 506 is fixed to the bottom of the tester body 1 through the positioning frame 502, the tester body 1 can be fixed to one side of the battery. At the same time, when the strong magnet 506 has no adsorbent, the rubber suction cup 605 can be connected to the surface of the battery. After the rubber suction cup 605 is connected to the surface of the battery, it can be pressed. The pressure tester body 1 is pressed. Since a screw hole is provided at the bottom of the tester body 1, the connecting screw 603 is connected to the bottom of the tester body 1 through the screw hole. The connecting screw 603 is connected to the connecting base 601 through the connecting through hole 602. The connecting base 601 is fixed to the bottom of the tester body 1 through the connecting screw 603. The rubber suction cup 605 is connected to the connecting base 601 through the connecting support leg 604. Therefore, after the tester body 1 is pressed, the air in the rubber suction cup 605 will be discharged. After the air in the rubber suction cup 605 is discharged, it will be adsorbed on the surface of the battery, thereby fixing the tester body 1 on the battery, making it convenient for the testing staff to observe the display screen 2.
