[0023] The elastic sleeve 11 can play a buffering role when the connecting line 12 is greatly bent, so that the connecting line 12 is not easy to break. The protection block 10 is set at one end of the connecting line 12 close to the connector 9. The rubber protrusions are evenly distributed on the protection block 10, which is convenient for plugging and unplugging;

[0024] A charging part 2 is provided on the top of the charger body 1, and a charging slot 7 is evenly opened inside the charging part 2, and a positive pole 3 and a negative pole 4 are respectively provided at both ends of the charging slot 7. A battery to be charged is placed in the charging slot 7, and both ends of the battery are in contact with the positive pole 3 and the negative pole 4 respectively;

[0025] The limiting mechanism 8 is arranged at one end of the charging slot 7 away from the positive pole 3. The limiting mechanism 8 includes a groove 801, a pressure plate 802, a return spring 803 and a guide groove 804. The groove 801 is provided with a pressure plate 802 through the return spring 803, and one end of the pressure plate 802 is connected to the negative pole 4.

[0026] When the battery contacts the negative electrode 4, a squeezing force is generated thereon, and the squeezing force causes the pressure plate 802 to squeeze the return spring 803 in the groove 801, and the battery is fixed and limited in the charging slot 7 by the rebound effect of the return spring 803;

[0027] Both sides of the groove 801 are provided with guide grooves 804, and both sides of the pressure plate 802 are slidably connected to the guide grooves 804 through guide blocks;

[0028] At the same time, when the return spring 803 is deformed and restored, both sides of the pressure plate 802 slide in the guide groove 804 through the guide blocks, which plays a guiding role, so that the return spring 803 is not easily twisted;

[0029] The heat dissipation mechanism 6 is arranged below the charger body 1. The heat dissipation mechanism 6 includes a bracket 601, a heat dissipation fan 602 and blades 605. The bracket 601 is arranged at the bottom of the charger body 1. The heat dissipation fan 602 is arranged inside the bracket 601, and the blades 605 are evenly distributed on the outside of the heat dissipation fan 602.

[0030] The heat dissipation mechanism 6 further includes a heat dissipation plate 603 and heat dissipation fins 604, and the heat dissipation plate 603 is connected to the bottom end of the circuit board 5, and the heat dissipation fins 604 are evenly distributed on the bottom end of the heat dissipation plate 603, and the bottom ends of the heat dissipation fins 604 extend to the outside of the charger body 1;

[0031] During charging, the heat on the circuit board 5 is absorbed by the heat sink 603. The tops of the heat sink fins 604 are connected to the heat sink 603, and the bottoms extend to the outside of the charger body 1 to conduct heat out. At the same time, the heat dissipation fan 602 fixed on the bracket 601 drives the blades 605 to rotate, generating a circulating airflow under the charger body 1 to take away the heat. The charger body 1 can be cooled when it is working, with high heat dissipation efficiency, which improves the safety during charging.

[0032] The heat dissipation mechanism 6 further includes ribs 606, and the ribs 606 are all arranged on the blades 605. There are three groups of ribs 606 on the blades 605. The ribs 606 increase along the extension direction of the blades 605, so that surrounding airflow is generated when the blades 605 rotate, which plays a role in reducing noise.

[0033] The specific model and specifications of the circuit board 5 need to be determined by selection calculation based on the specification parameters of the device, and the selection calculation method is a prior art, so it will not be described in detail.

[0034] Working principle: When the embodiment of the present application is in use, the plug at one end of the connecting line 12 is connected to the socket for power supply. An elastic sleeve 11 is sleeved on the connecting line 12, which can play a buffering role when the connecting line 12 is greatly bent, so that the connecting line 12 is not easy to break. The protective block 10 is arranged at the end of the connecting line 12 close to the connector 9. The rubber protrusions are evenly distributed on the protective block 10, which is convenient for plugging and unplugging. Then, the battery to be charged is placed in the charging slot 7, and the two ends of the battery are in contact with the positive pole 3 and the negative pole 4 respectively. When the battery contacts the negative pole 4, an extrusion force is generated thereon. The extrusion force prompts the pressure plate 802 to squeeze the reset spring 803 in the groove 801, and the battery is fixed in the charging slot 7 by the rebound effect of the reset spring 803. At the same time, the reset spring When 803 is deformed and restored, both sides of the pressure plate 802 slide in the guide groove 804 through the guide blocks, which plays a guiding role, making it difficult for the reset spring 803 to be twisted. When charging, the heat on the circuit board 5 is absorbed by the heat sink 603. The tops of the heat sink fins 604 are connected to the heat sink 603, and the bottoms extend to the outside of the charger body 1 to export the heat. At the same time, the heat dissipation fan 602 fixed on the bracket 601 drives the blades 605 to rotate, generating a circulating airflow under the charger body 1 to take away the heat. The charger body 1 can be cooled when it is working, with high heat dissipation efficiency, which improves the safety during charging. When the blades 605 rotate, a surrounding airflow is generated through the ribs 606 to reduce noise.
