[0027] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth to explain in detail that the buffer layer 304 is fixedly connected to the left end of the moving ring 303, and the material of the buffer layer 304 is set to be a rubber material;

[0028] By providing the buffer layer 304 made of rubber material, a buffer can be increased when the movable ring 303 contacts the vehicle body, thereby avoiding damage to the vehicle body.

[0029] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth to explain in detail that the slider 305 is symmetrically fixedly connected to the upper and lower parts of the right side of the moving ring 303, and the upper and lower parts of the handle 1 are symmetrically provided with a slide groove 306, and the slider 305 is slidably connected to the inside of the slide groove 306;

[0030] By sliding the slider 305 to be connected to the inside of the slide groove 306, the moving ring 303 can be ensured to slide stably on the outside of the handle 1, thereby ensuring the stable separation of the charging head 2 from the vehicle body.

[0031] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth to explain in detail that the positioning rod 307 is slidably connected to both sides of the moving ring 303, the baffle 308 is fixedly connected to one end of the positioning rod 307 away from the moving ring 303, the second spring 309 is fixedly connected between the baffle 308 and the outer wall of the moving ring 303, and is sleeved on the outside of the positioning rod 307, and a positioning hole 310 adapted to the positioning rod 307 is opened on the front of the grip 1;

[0032] The elastic action of the second spring 309 drives the positioning rod 307 to reset, so that the positioning rod 307 extends into the interior of the positioning hole 310, thereby fixing the position of the movable ring 303, avoiding the detachment of the charging head 2 during charging, and improving the stability of charging.

[0033] According to the above working process, it can be known that: through the disengagement mechanism 3, when charging is completed, the baffle 308 is pulled to disengage the positioning rod 307 from the interior of the positioning hole 310, and under the elastic action of the first spring 302, the movable ring 303 is driven to reset, which is convenient for disengaging the charging head 2 from the interior of the charging port, saving time and effort in use, and improving the practicality of the device.

[0034] Further as Figure 2 , Figure 4 and Figure 5 As shown, it is worth specifically explaining that the protection mechanism 5 is composed of a fixed semi-ring 501, a protection semi-ring 502, a connecting semi-ring 503, a third spring 504, a fixed block 505, a connecting block 507, a positioning column 509, a baffle 510 and a fourth spring 511. The fixed semi-ring 501 is symmetrically arranged on the outside of the power cord 4, the protection semi-ring 502 is fixedly connected to one side of the fixed semi-ring 501, the connecting semi-ring 503 is fixedly connected to the other side of the fixed semi-ring 501, and the connecting semi-ring 503 is evenly arranged, and the third spring 504 is evenly fixedly connected between the connecting semi-rings 503;

[0035] By connecting the connecting half ring 503 and the third spring 504, when the power cord 4 is bent, the elastic effect of the third spring 504 can drive the power cord 4 to recover, generate a reaction force with the bending of the power cord 4, and reduce the damage to the power cord 4 caused by the bending.

[0036] Further as Figure 2 , Figure 4 and Figure 5 As shown, it is worth specifically explaining that the fixed block 505 is fixedly connected to the end of the fixed half ring 501 on one side, and a positioning groove 508 compatible with the fixed block 505 is provided at the end of the fixed half ring 501 on the other side. The connecting block 507 is fixedly connected to the end of the connecting half ring 503, and a groove compatible with the connecting block 507 is provided at the end of the connecting half ring 503 on the other side. The positioning column 509 is slidably connected between the positioning groove 508 and the fixed half ring 501, the baffle 510 is fixedly connected to the end of the positioning column 509 away from the fixed half ring 501, the fourth spring 511 is symmetrically fixedly connected between the baffle 510 and the outer wall of the fixed half ring 501, and a limiting groove 506 compatible with the positioning column 509 is provided on one side of the fixed block 505.

[0037] Further as Figure 2 , Figure 4 and Figure 5 As shown, it is worth to explain in detail that the fixing half ring 501, the protection half ring 502, and the connecting half ring 503 are all set to be made of silicone material;

[0038] The silicone material can hold the power cord 4 without limiting the bending of the power cord 4, thereby improving the practicality of the mechanism.

[0039] The present invention has the following working process: when in use, hold the handle 1 and insert the charging head 2 into the charging port for charging. When charging is completed, pull out the baffle 308 to drive the positioning rod 307 to disengage from the positioning hole 310, thereby releasing the position restriction of the moving ring 303. Due to the elastic effect of the first spring 302, the moving ring 303 is driven to move, and the buffer layer 304 is pushed against the vehicle body to push the charging head 2 out of the charging port, so that the charging head 2 can be disengaged without any effort. At the same time, when in use, the protective The mechanism 5 is stuck on the outside of the connection position between the power cord 4 and the handle 1. First, pull the baffle 510 to drive the positioning column 509 to move out of the positioning groove 508, then insert the limiting groove 506 into the positioning groove 508, insert the connecting block 507 into the groove, and then release the pulled baffle 510. Under the elastic action of the fourth spring 511, the positioning column 509 is driven to reset, so that the positioning column 509 extends into the limiting groove 506, fixes the connection of the fixed semi-rings 501 on both sides, and improves the protection mechanism 5 for the connection protection of the power cord 4.

[0040] In summary: through the provided disengagement mechanism 3, when charging is completed, the baffle 308 is pulled to disengage the positioning rod 307 from the interior of the positioning hole 310, and under the elastic action of the first spring 302, the movable ring 303 is driven to reset, so that the charging head 2 can be disengaged from the interior of the charging port, which saves time and effort in use and improves the practicality of the device; through the provided protection mechanism 5, the pulling between the power cord 4 and the handle 1 can be reduced, thereby reinforcing the connection position between the handle 1 and the power cord 4 and extending the service life of the power cord 4.
