The working principle of the quick-release connector 30 of the underwater propeller is as follows: since the eccentric wheel 33 is an eccentric wheel and rotates around the eccentric rotation shaft 333, when the eccentric wheel rotates, the distance between the edge of the eccentric wheel 33 facing the direction of the nut 3113 and the nut 3113 changes, and when the distance increases, the elastic member 39 ejects the first connector 35 and the second connector 37 due to the force of the elastic member 39, the distance between the first connector 35 and the second connector 37 increases, that is, the distance between the first clamping portion 356 and the second clamping portion 374 increases, so that the host 10 is released, and the host 10 can be taken out; when the distance is reduced, the elastic member 39 is compressed, and the distance between the first connector 35 and the second connector 37 is reduced, that is, the distance between the first clamping portion 356 and the second clamping portion 374 is reduced, so that the host 10 is clamped.

In this embodiment, the first clamping portion 356 and the second clamping portion 374 are hooks, the host 10 is a first groove (not shown) and a second groove (not shown) that are disposed opposite to each other, an opening of the first groove is disposed towards the first clamping portion 356, and the second groove is disposed towards the second clamping portion 374 to cooperate with the clamping.

Compared with the prior art, the quick-release connector 30 for the underwater propeller provided by the utility model has the advantages that the first connector 35 is used for fixing the handle 20, the distance between the first clamping part 356 and the second clamping part 374 can be changed by rotating the eccentric rotating wheel 33, the host 10 can be matched and clamped or released, the handle 20 and the host 10 can be dismounted and mounted later, the quick-release and the mounting and the dismounting of the handle 20 and the host 10 can be completed only by rotating the eccentric rotating wheel 33, and the quick-release connector is convenient to dismount and mount and convenient for a user to store and carry; further, due to the convenience of disassembly and assembly, when the manufacturer sells, the handle 20 and the host 10 which are separately provided with the underwater propeller quick-release connector 30 can be sold to the user, so that the packaging and transportation cost is reduced.

Moreover, by rotating the nut 3113, the distance between the nut 3113 and the eccentric wheel 33 can be adjusted, so as to adjust the maximum distance between the first clamping portion 356 and the second clamping portion 374, so as to adapt to the sizes of the hosts 10 with different sizes, and the application range is wide.

While the utility model has been described with respect to the above embodiments, it should be noted that modifications can be made by those skilled in the art without departing from the inventive concept, and these are all within the scope of the utility model.
