The jack 23 on the B plate 21 of the female module 2 is closely matched with the public pin 12, the hole diameter tolerance is controlled within a very small range, ensures the accuracy when the public pin 12 is inserted.

[0022] The group of cylindrical first limiting blocks 13 on the A plate 11 are uniformly distributed around the pin 12, and the recesses 131 have high machining precision and can be tightly coupled with the protrusions 241 of the second limiting blocks 24 on the B plate 21, so that the two modules are effectively prevented from deviating during the abutting of the male module 1 and the female module 2, and the stability of the connection is enhanced.

[0023] The support shell 221 of the lock trigger assembly 22 is made of high-strength aluminum alloy and is vertically installed on the B plate 21 through a precision machining process, the position of the flange 2211 at the bottom and the mounting hole on the mounting lug 2212 is accurate, and the B plate 21 is firmly and reliably screwed, and can withstand a certain external impact without loosening.
