As shown in fig. 1 to 4, the quick connector 100 of the present invention includes a connecting seat 1, a connecting head 2 and locking components 3 symmetrically disposed on the connecting seat 1, wherein the connecting seat 1 is provided with a receiving hole 11 along a central axis direction, and the connecting head 2 can be inserted into or withdrawn from the receiving hole 11; two sides of the connecting seat 1 are symmetrically provided with accommodating grooves 12 with open outer sides, and the accommodating grooves 12 are used for accommodating the locking assemblies 3. The locking assembly 3 includes a driving member 31, a locking pin 32 and a first elastic member 33, through holes 13 are symmetrically formed at both sides of the connecting base 1 along a direction perpendicular to the central axis, and the through holes 13 are disposed at the bottom of the receiving groove 12. Annular groove 2a has been seted up to connector 2 lateral wall, driving piece 31 pin joint in connecting seat 1 and one end with stop pin 32 is connected, first elastic component 33 set up in driving piece 31 with between the connecting seat 1. The locking pin 32 is slidably disposed in the through hole 13 to extend into or withdraw from the accommodating hole 11; by inserting the connector 2 into the receiving hole 11, the locking pin 32 extends out of the receiving hole 11 and is locked in the annular groove 2a, so that the connector base 1 is fixedly connected to the connector base 1. The first elastic member 33 is a torsion spring, which can make the driving member 31 keep pushing the locking pin 32 into the accommodating hole 11, so that it is automatically connected with the connecting head 2 in a snap-fit manner.

Referring to fig. 2, the driving member 31 includes a pivoting portion 311, a clamping portion 312 and a pressing portion 313, the pivoting portion 311 is pivoted to the connecting base 1 through a rotating shaft 314, the clamping portion 312 extends out of two fork arms 312a, a receiving groove 312b with one side open is formed between the two fork arms 312a, openings 321 are symmetrically formed on the outer side of the locking pin 32, when the clamping portion 312 is connected to the locking pin 32, the fork arms 312a are respectively clamped in the openings 321, and the locking pin 32 is inserted into the receiving groove 312 b. This enables the locking pin 32 to be quickly coupled to the driving member 31, effectively improving the convenience of assembly. The pressing portion 313 extends outward from one end of the pivoting portion 311 to extend out of the connecting seat 1. By providing the pressing portion 313, the driving member 31 can be operated more easily, and the convenience of operation can be improved.

As shown in fig. 2 and 3, the connector 2 includes a connecting rod 21, a sleeve 22 and a second elastic member 23, the annular groove 2a is disposed on the connecting rod 21, the sleeve 22 is slidably sleeved outside the connecting rod 21, the second elastic member 23 is disposed between the sleeve 22 and the connecting rod 21 to restore the connecting rod 21, and at least one annular edge 221 extends outward from an outer side of the sleeve 22. The annular edge 221 on the lower side can be conveniently operated and can also be shielded at the connection position of the connecting rod 21 and the connecting seat 22. Through will the external member 22 set up in outside the connecting rod 21 to set up between the two the second elastic component 23 can the connecting rod 21 connect in during connecting seat 1, make the external member 22 keep conflicting in the surface of connecting seat 1, thereby both can protect connecting rod 21 can cover again the surface of holding hole 11 prevents to give under extreme road conditions connecting seat 1 and connector 2 drive the hidden danger. Specifically, one end of the connecting rod close to the annular groove 2a is provided with a guiding conical surface, which can enable the connecting rod 21 to be accurately inserted into the accommodating hole 11 and enable the locking pin 32 to automatically escape from the connecting rod 21. One end of the connecting rod 21, which is far away from the annular groove 2a, is provided with a universal ball joint 24. This enables the trailer to be driven over uneven surfaces and requires less location and attitude for the trailer to be mounted.
