The outer diameter of the third boost block 51 is completely consistent with the inner diameter of the first limiting groove 222, so that the third boost block 51 can enter the first limiting groove 222 along the trajectory of the first auxiliary slide groove 221 and completely abut against the inner wall of the first limiting groove 222 for limiting. The size of the fourth boost block 52 matches the size of the second auxiliary slide groove 231, and the fourth boost block 52 enters from the open end of the second auxiliary slide groove 231, and the fourth boost block 52 is slidably connected to the second auxiliary slide groove 231. The outer diameter of the fourth boosting block 52 is completely consistent with the inner diameter of the second limiting groove 232, so that the fourth boosting block 52 can enter the second limiting groove 232 along the trajectory of the second auxiliary sliding groove 231 and completely abut against the inner wall of the second limiting groove 232 for limiting.

[0037] When the charging gun 5 is plugged into the connecting seat 1, the third booster block 51 and the fourth booster block 52 are respectively located at the opening ends of the first assisting slide groove 221 and the second assisting slide groove 231, and pressure is applied to the booster handle 2. The third booster block 51 and the fourth booster block 52 always fit the first assisting slide groove 221 and the second assisting slide groove 231 away from the inner side wall of the connecting seat 1, and the first booster plate 22 and the second booster plate 23 move downward so that the axial pressure on the inside always presses the third booster block 51 and the fourth booster block 52 to slide along the first assisting slide groove 221 and the second assisting slide groove 231 away from the inner side wall of the connecting seat 1 and enter the first limiting groove 222 and the second limiting groove 232.

[0038] Working principle:

[0039] During use, this solution replaces the connecting piece connected to the connecting end of the connecting socket with a charging gun, and the third booster block and the fourth booster block on both sides of the charging gun respectively abut against the opening ends of the first booster groove and the second booster groove on the inner walls of both sides of the booster handle, so as to enable the booster handle to boost the charging gun.
