As shown in fig. 3, 4A and 4B, the rotational force receiving member 40 has a shaft portion 42 and two position-limiting posts 48 radially extending from the shaft portion 42, the shaft portion 40 is parallel to the axis a of the tube portion 32 of the connecting member 30, the two position-limiting posts 48 extend into the first groove 356 and the second groove 376, so that when the rotational force receiving member 40 rotates counterclockwise, the two position-limiting posts 48 respectively abut against an axial extension 352 of the first position-limiting portion 35 and a first axial extension 372 of the second position-limiting portion 37, so that the connecting member 30 can rotate together with the rotational force receiving member 40. The structure of the rotational force receiving member 40 can be varied, and the basic function can be achieved by the above basic structure, in this embodiment, the rotational force receiving member 40 is composed of a shaft member 41, a ball 45 and a limit pin 47, as shown in fig. 7, the shaft member 41 has the shaft portion 42 and a claw portion 43, the claw portion 43 is disposed at one end of the shaft portion 42 for engaging with the driving member 18 of the electronic image forming apparatus 14, so that the driving member 18 can drive the shaft member 41 to rotate, the ball 45 has a hollow chamber 46 into which the shaft member 41 can extend, the limit pin 47 passes through the ball 45 and the shaft portion 42 along the radial direction of the shaft member 41, and two ends of the limit pin 47 are exposed out of the ball 45 to form the two limit posts 48.

The connecting member 30b also has the equivalent function to that of the first preferred embodiment.
In fact, as long as a gap is left between the first limiting part in the connecting piece and the inner edge of the pipe part, the invention protects the first limiting part and the second limiting part, namely the second limiting part extends from the inner edge of the pipe part to the first limiting part, or the second limiting part extends from the bottom to the opening and a gap is left between the second limiting part and the inner edge of the pipe part; the first and second limiting parts can be changed in structure and shape, and the invention is protected as long as the first and second grooves are respectively provided for the two limiting posts of the rotating force receiving part to extend into. The gap may be present or absent,
in summary, the connecting member of the present invention can be assembled with a rotational force receiving member, such that the rotational force receiving member can freely swing within a predetermined angle range relative to the connecting member without being separated from the connecting member, thereby achieving the objective of the present invention.
