Further, in the above structure, it is easy for a child to rotate the protection cover 3 by himself so that the two-hole docking hole 31 and the three-hole docking hole 32 are aligned with the two-hole socket 92 and the three-hole socket 93, respectively, and therefore, in a further preferred embodiment, as shown in fig. 3, the rotating shaft 2 is a telescopic shaft including an outer shaft 21 and an inner shaft 22 slidably inserted into the outer shaft, the maximum opening length of the telescopic shaft is greater than the distance between the upper surface 91 and the bottom plate 15, the inner shaft 22 has a circumferential surface provided with a blocking disc 23, and when the blocking disc 23 abuts against the upper plate of the terminal body 9, the protection cover 3 on the telescopic shaft 2 is positioned in the circular hole 101 of the limiting plate 10 and is engaged with the circular hole 101.

In this configuration, the rotation shaft 2 does not need to be rotated by a bearing, but as shown in fig. 3, the inner shaft 22 may be rotated with respect to the outer shaft 21 by making the inner hole of the outer shaft 21 a circular hole by making the inner shaft 22 a circular shaft, and at this time, the outer shaft 21 may be fixed to the bottom plate 11 of the socket case 1 by a bolt.

As shown in fig. 4, the outer circumference of the rotating shaft 2 is sleeved with a spring 4, one end of the spring 4 is fixed in the socket box 1, the other end of the spring 4 abuts against the blocking disc 23, a through hole for the spring 4 to pass through is formed in the terminal main body 9, the spring 4 normally abuts against the blocking disc 23 and the upper panel of the terminal main body 9, and the protecting cover 3 on the rotating shaft 2 keeps a gap with the upper surface 91, wherein the gap is not smaller than the thickness of the protecting cover 3.

As shown in fig. 4 and 5, the circumferential surface of the protective cover 3 is a saw-toothed shape, the terminal main body 9 is detachably provided with a limiting plate 10 for limiting rotation of the protective cover 3, the limiting plate 10 is provided with a circular hole 101 matched with the protective cover 3, the hole wall of the circular hole 101 is in a tooth shape matched with the circumferential surface of the protective cover 3, and the limiting plate 10 and the terminal main body 9 can be in a splicing structure, i.e., the limiting plate 10 can be in a clamping connection with the terminal main body 9, and the specific structure of the structure is in a clamping connection with the existing socket panel and the socket main body, which is not repeated herein.

Therefore, in a normal state, the saw-tooth shape on the protecting cover 3 is meshed with the tooth shape of the round hole, and at this time, the protecting cover 3 cannot rotate; when needs are rotatory, press downwards protective cover 3 makes protective cover 3 and limiting plate 10 break away from, can rotate protective cover 3 this moment, thereby spring 4 through chooseing for use stiffness coefficient to be greater than children's finger pressing force can effectually avoid children's maloperation.
