However, when the first pushing plate 519 is released, the first positioning upper plate 51 and the second positioning upper plate 54 may fall back down under the action of gravity, and the line is clamped again, which may affect the maintenance of the line. In order to avoid the occurrence of the above-mentioned situation, as shown in fig. 1 and 5, two sets of first limiting mechanisms 9 are symmetrically installed on the top surface of the cover body 2, the first limiting mechanisms 9 include a pawl 91, a first spring 92 and a fixing plate 93, the pawl 91 is rotationally connected with the top surface of the cover body 2, the fixing plate 93 is fixedly connected with the top surface of the cover body 2, the first spring 92 is connected between the pawl 91 and the fixing plate 93, and the pawl 91 can perform unidirectional limiting on the first push plate 519. Specifically, when two first pushing plates 519 are pushed toward the housing 1 at the same time, the first pushing plates 519 can push the pawl 91, and the pawl 91 pulls the first spring 92, so that the first pushing plates 519 pass smoothly, but if the first pushing plates 519 move in opposite directions, the pawl 91 blocks the movement, and the pawl 91 needs to be manually pulled to move the first pushing plates 519 in opposite directions, so that the first pushing plates 519 are limited in one direction.
As shown in fig. 1, 7-10, two second travel grooves 4 are formed in the front surface of the cover body 2, and the two second travel grooves 4 are respectively connected with two quick release assemblies 6 in a one-to-one correspondence manner.

When the quick release assembly 6 is operated, the second push plate 65 is pushed, the second push plate 65 drives the connecting plate 613 to displace through the connecting rod 64, the connecting plate 613 extrudes the fifth spring 69 to form a compressed state, the connecting plate 613 drives the clamping shell 66 to move through the connecting rod 612, the clamping shell 66 simultaneously drives the clamping block 67 to move, meanwhile, the clamping block 67 is extruded by the limiting frame 62, and the clamping block 67 is retracted into the clamping shell 66, so that the clamping block 67 is not clamped in the clamping groove 7, and the cover body 2 and the shell 1 can be separated.
When the cover 2 is separated from the housing 1, if the induction assembly 5 does not loosen the circuit, the circuit is pulled off by the power receiving module 11 when the cover 2 moves. In order to avoid the occurrence of the above-mentioned situation, as shown in fig. 1, fig. 2, fig. 3, fig. 8, fig. 9, fig. 10, the lid 2 is connected with two sets of symmetrical second stop mechanisms, the second stop mechanisms include an auxiliary groove 131 that is opened on the surface of the lid 2, the auxiliary groove 131 does not run through the surface of the lid 2, one end sliding connection of the auxiliary groove 131 has a first spacing post 132, the other end sliding connection has a second spacing post 134, be connected with auxiliary rope 133 between first spacing post 132 and the second spacing post 134, auxiliary rope 133 lays along auxiliary groove 131, auxiliary groove 131 is equipped with the clamp plate, avoid auxiliary rope 133 to deviate from, be connected with sixth spring 135 between the inner wall of second spacing post 134 and auxiliary groove 131, second spacing post 134 can be used for restricting the removal of second push pedal 65, first push pedal 519 can promote first spacing post 132 removal.
Specifically, in a state where the induction assembly 5 does not release the line and the cover 2 is not opened, the second limiting post 134 is located at one side of the second push plate 65, and at this time, the second limiting post 134 blocks the second push plate 65 from moving. In the process that the first push plate 519 of the angelica nano assembly 5 moves towards the shell 1, the first push plate 519 pushes the first limiting column 132 to move, the first limiting column 132 pulls the second limiting column 134 through the auxiliary rope 133, the second limiting column 134 pulls the sixth spring 135 to move upwards, at the moment, the first push plate 519 pulls the pawl 91, the pawl 91 carries out unidirectional limiting on the first push plate 519, the first push plate 519 cannot move reversely, meanwhile, after the second limiting column 134 moves upwards for a certain distance, the second push plate 65 is not limited any more, the second push plate 65 can enable the quick-release assembly 6 to act, and therefore the cover body 2 can be separated from the shell 1.
