The quick-release connector 3 allows for fastening the connection between the second connector 2 and the first T-block 14, enabling rapid connection and installation. It facilitates inserting the fixing connecting post 34 into the inner side of the first through hole 15 and the second through hole 25, while simultaneously allowing one of the connecting sleeves 31 to be fitted onto the outer side of the fixing connecting post 34. The connecting sleeve 31, under the action of the fixing inner groove 32 and the fixing slot 33, fits onto the outer surface of the first T-block 14 and the second T-block 24. Then, the connecting mounting plate 37 and the fixing sleeve 38 are moved and fitted onto the outer side of the fixing connecting post 34. Finally, the connecting limiting spring 310 is secured inside the fixing groove 35, fixing the connecting post 34. The connection and assembly are facilitated by the connection and restriction between the sleeve 38 and the fixed sleeve, making the operation convenient.

[0017] In another embodiment, such as Figure 2As shown, the second connector 2 includes a second connecting sleeve 21. One end of the second connecting sleeve 21 is fixedly connected to a connecting frame 22.

At the same time, the fixed connecting post 34 can be stably inserted into the inside of the fixed socket 36, making the operation convenient and quick.

[0024] The working principle of this utility model is as follows: During use, when the first connecting member 1 needs to be disassembled for inspection and maintenance, the connecting limiting spring 310 is first disassembled so that it can disengage from the inside of the fixing groove 35, thus no longer restricting the connection between the fixing connecting post 34 and the fixing sleeve 38. Then, the fixing connecting block 39 is moved, which drives the fixing sleeve 38 and the connecting mounting plate 37 to move, so that the fixing sleeve 38 and the connecting mounting plate 37 disengage from the outside of the surface of the fixing connecting post 34. Subsequently, the connecting sleeve blocks 31 are separated from each other, so that the fixing connecting post 34 disengages from the inside of the fixing insertion hole 36, and the connection between the first T-shaped block 14 and the second T-shaped block 24 is no longer restricted. Finally, the threaded connecting sleeve 12 and the threaded connecting block 27 are rotated and disassembled, thereby disassembling the first connecting member 1 for inspection, maintenance, or disinfection. The overall structure is simple and the operation is convenient and quick.

[0025] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are quite specific and detailed, but they should not be construed as limiting the scope of this utility model patent.
