The present disclosure relates to a handheld swimming pool sewage suction machine, including a body and a suction head, the body being therein with a first water pump, a filtering device, a second water pump, a main channel and a bypass channel, the filtering device and the first water pump being at least partially located in the main channel, and the second water pump being at least partially located in the bypass channel; wherein the first water pump enables water to flow into the main channel from a first water inlet and to be discharged from a body outlet after filtration by the filtering device; and the second water pump enables the water to flow into the main channel from a second water inlet of the bypass channel when a predetermined condition is fulfilled. The handheld swimming pool sewage suction machine can start operating under different water depth conditions.

Handheld swimming pool sewage suction machine

A double cardan constant velocity joint including a housing extending between a housing first end and a housing second end. A first yoke is pivotably coupled to the housing first end by a first spider. The first yoke extends between a first end having a socket and a second end configured for attachment to a first shaft. A second yoke is pivotably coupled to the housing second end by a second spider. The second yoke extends between a first end having a ball stud and a second end configured for attachment to a second shaft. A ball is disposed in the socket, wherein the ball has a recessed pocket for receipt of the ball stud. A biasing member is disposed in the recessed pocket to impart a bias on the ball, wherein pivotal movement of the first yoke and the second yoke causes the ball to translate in the socket.

Double cardan constant velocity adjustable joint
