[0065] More specifically, the second fixing structure 23 is arranged on the middle outer side of the second semicircular ring 21, and is used to abut against the clamping structure 3. It can be understood that the clamping structure 3 applies downward and inward pressure to the second fixing seat 2 through the second fixing structure 23 to fix the second fixing seat 2 on the first fixing seat 1.

[0066] See also Figure 3 In some embodiments, the second fixing structure 23 has a first surface 231 , a second surface 232 , a third surface 233 and a fourth surface 234 .

[0073] Specifically, the third fixing structure 17 includes a plurality of outer protrusions 171 and a pair of inner protrusions 172. The plurality of outer protrusions 171 are arranged on the outer side of the first semicircular ring 11, and the pair of inner protrusions 172 are arranged on the inner side of the junction of the two side connecting structures 12 and the first fixing structure 13; more specifically, the outer protrusions 171 and the inner protrusions 172 both have a third fixing hole 173, and the charging gun 4 has a hole corresponding to the position of the third fixing hole 173. The third fixing hole 173 and the hole are fixedly connected by the second fixing member 7, so that the first fixing seat 1 can be fixedly installed on the charging gun 4.

A plurality of first protrusions 1112 are evenly spaced apart on the first curved portion 1111, and the outer shape of the first protrusions 1112 is a protruding square. It can be understood that since a plurality of first protrusions 1112 are spaced apart on the first arc portion, the pressure of the first clamping tooth 111 on the cable 5 is not uniform, that is, the first clamping tooth 111 applies higher pressure and lower pressure to the cable 5 at intervals, so that the cable 5 is not easy to fall off.

[0079] See also Figure 3 In some embodiments, the second latching tooth 211 includes a second curved portion 2111 and a plurality of second protrusions 2112 .
