The first locking component 4 can cooperate with the second conductive sheet lifting base 322. When the first locking component 4 cooperates When the second conductive sheet lifting base 322 is on the second conductive sheet lifting base 322, the second conductive sheet lifting base 322 is in a lowered state, and the first spring is compressed at this time; when the first locking component 4 is separated from the second conductive sheet lifting base 322, the first spring Extend, the second conductive sheet lifting base 322 moves upward along the first lifting base guide groove 13, and the second conductive sheet lifting base 322 is in a raised state.

As shown in Figures 9 to 11, specifically, the second conductive sheet lifting base 322 is provided with a first locking groove 3222 on the side facing the first locking component 4. The first locking component 4 is in contact with the second conductive sheet lifting base. 322, a part of the first locking component 4 can extend into the first locking groove 3222, thereby limiting the movement of the second conductive sheet lifting base 322 in the vertical direction, thereby achieving locking of the second conductive sheet lifting base 322. Further, the first locking assembly 4 includes a first locking block 41. The first locking block 41 is located between the two first conductive sheets 311, and the first locking block 41 is slidably disposed on the upper housing 1, and the sliding direction is along Along the installation direction of the installation port 11, a first locking end 411 is protrudingly provided on the side of the first locking block 41 facing the second conductive sheet lifting base 322, and the first locking end 411 can extend into the first locking groove 3222.
