The sliding assembly continues to slide downward and compresses the second spring 52 through the first spring 51. When the sliding assembly slides downward to the corresponding position, it acts on the lower locking block 4 to make the lower locking blocks 4 open to each other, thereby causing the second spring 52 to be ejected downward out of the storage barrel 6. At this time, the circuit board is located at the bottom of the storage barrel 6. The second spring 52 is ejected downward out of the storage barrel 6 and then inserted onto the circuit board; the second spring 52 is the spring 5 at the bottom of the inner cavity 20, and the first spring 51 is the spring 5 arranged adjacent to the second spring 52; the spring 5 is a cylindrical touch spring.

[0030] The sliding assembly comprises a sliding sleeve 7 and a locking sleeve 8 which are sequentially arranged up and down. The sliding sleeve 7 and the locking sleeve 8 are elastically connected.
