Therefore, these and other directional terms should not be construed as limiting terms.

The first embodiment is as follows:

referring to fig. 1-5, a first embodiment of a quick release assembly is shown.

As shown in fig. 1-4, the quick release assembly 10 includes a plug set 1 and a receptacle set 2;

the plug group 1 comprises an insert rod 11, and an insert part 111 is arranged on the insert rod 11;

the socket group 2 comprises a guide cylinder 21, an elastic piece 22 and a lock rod 23, wherein the guide cylinder 21 comprises a slide way 212 along the vertical direction, the insert rod 11 can be inserted into the slide way 212 of the guide cylinder 21, a lock hole 211 is further formed in the cylinder wall of the guide cylinder 21, and an insertion end 231 of the lock rod 23 is inserted into the lock hole 211 and enters the guide cylinder 21;

in the locking state, the insertion rod 11 is inserted into the guide cylinder 21, the insertion end 231 of the lock rod 23 is inserted into the insertion part 111 to be locked, and the elastic piece 22 presses the lock rod 23;

in the disassembled state, the lock rod 23 is pushed to compress the elastic member 22, the insertion end of the lock rod 23 is separated from the insertion part 111, and the insertion rod 11 is pulled out from the guide cylinder 21.

Specifically, as shown in fig. 1, the insertion rod 11 is cylindrical, and the insertion portion 111 forms a continuous circle in the circumferential direction of the insertion rod 11.

As shown in fig. 3, the guide cylinder 21 is a hollow cylinder, the guide cylinder 21 is arranged in the vertical direction, and the insertion rod 11 can be inserted into the guide cylinder 21 from the bottom up.

In this embodiment, the plug group 1 is located below the socket group 2, so the insert rod 11 needs to be inserted into the guide cylinder 21 from bottom to top.

Alternatively, the plug group 1 may be located above the socket group 2, and the plug group 1 is inserted into the guide cylinder 21 from top to bottom.

As shown in fig. 4-5, the guide cylinder 21 is provided with a locking hole 211, and the locking hole 211 transversely penetrates through the outer wall and the inner wall of the guide cylinder 21.

As shown in fig. 4, the elastic member 22 is installed at one side of the insertion end 231 of the locking lever 23. The lock lever 23 is made of a cylindrical rod member. One end (insertion end 231) of the lock lever 23 is bent and inserted into the lock hole 211 bypassing the guide cylinder 21, and the other end of the lock lever 23 is bent downward to form a pushing portion 232, and the pushing portion 232 is flattened to facilitate the pressing operation.

After the insertion rod 11 is inserted into the slide 212 of the guide cylinder 21, as shown in fig. 4 to 5, the insertion rod 11 can pass through the top of the slide 212, as shown in fig. 2.

Alternatively, the chute 212 may extend through the guide cylinder 21, or may be a closed-top structure.

Since the head 113 of the plunger 11 is bullet-shaped, the head 113 pushes the insertion end 231 of the lock lever 23 to move to the outside of the guide cylinder 21, and the insertion end 231 compresses the elastic member 22. When the head 113 passes through the lock bar 23, the inserting part 111 corresponds to the lock hole 211, the elastic element 22 pushes the inserting end 231 to move towards the inner side of the guiding cylinder 21, the inserting end 231 is inserted into the inserting part 111, and the locking of the plug group 1 and the socket group 2 is realized.
