In some embodiments, the first connecting member 122 has a connecting head 126 integrally formed at one end thereof, the second connecting member 124 is fixedly connected to a side of the connecting head 126 away from the first connecting member 122, and a radial dimension of the connecting head 126 is greater than a radial dimension of the second connecting member 124, so as to facilitate connection between the second connecting member 124 and the connecting head 126.
In practice, the second connector 124 is screwed to the connector 126. Specifically, a threaded hole is formed in a side of the connector 126 away from the first connector 122, and one end of the second connector 124 is threaded into the threaded hole, so that it is required to ensure that a radial dimension of the connector 126 is larger than a radial dimension of the second connector 124.
