A knob 21 for manual twisting is fixed to the rear end of the rotating cylinder 2. The rotating cylinder 2 is provided with an inner cavity 22 with an opening facing forward, and a first limit inlet and outlet 221 is provided at the front end of the inner cavity 22. A first transmission connector body 4 is installed in the inner cavity 22 for entering through the first limit inlet and outlet 221 and then rotating and dislocating to prevent it from falling off. After the first transmission connector body 4 is rotated and dislocated into place, it is connected to the rotating cylinder 2 through a first transmission connection structure 5 so that the two can move relative to each other in a longitudinal guide manner and rotate together when rotating. The front end of the first transmission connector body 4 is connected to a second transmission connector body 6, and a second transmission connection structure is provided between the second transmission connector body 6 and the first transmission connector body 4, which can adjust the relative front and rear positions of the two and then perform a transverse guide connection so that the two can move relative to each other in a transverse guide manner and rotate together when rotating.

[0027] As described above, the structure of this case is simple and easy to implement. The arrangement of the electric mechanism 3 and the knob member 21 facilitates the electric drive or manual drive of the rotation of the rotating cylinder 2. The first limit inlet and outlet 221 of the inner cavity 22 of the rotating cylinder 2 is arranged to facilitate the limited entry and exit of the first transmission connecting member body 4. The arrangement of the first transmission connecting structure 5 between the first transmission connecting member body 4 and the rotating cylinder 2 facilitates the first transmission connecting member body 4 to enter the inner cavity 22 through the first limit inlet and outlet 221 and then be connected to the rotating cylinder 2 by rotation and displacement, so that the two can move relative to each other in the longitudinal direction. And they rotate together when rotating, which is practical. The setting of the second transmission connection structure between the front end of the first transmission connection body 4 and the second transmission connection body 6, on the one hand, facilitates the adjustment of the front and rear positions of the second transmission connection body 6 relative to the first transmission connection body 4 to suit actual applications, and on the other hand, facilitates the relative longitudinal guided movement of the two after the transmission connection and rotates together when rotating, which is practical. In this way, the setting of the first transmission connection body 4 in this case can be suitable for the rotational transmission between the rotating cylinder 2 and the second transmission connection body 6 whose axes are not on the same straight line, which is practical.

[0028] like Figure 1 、 Figure 2 As shown, in a specific implementation, the rotating drum 2 is provided with an outer peripheral gear 31 , the electric mechanism 3 adopts a motor gear mechanism, and the electric mechanism 3 is provided with a gear meshing with the outer peripheral gear 31 .

A first front-to-back connecting port 42 is provided between the front end face of the first transmission connection member body 4 and the longitudinal guide channel 51, and a second front-to-back connecting port 60 corresponding to the first front-to-back connecting port 42 is provided between the front and rear ends of the second transmission connection member body 6.

[0030] As described above, the first transmission connection structure 5 in this case includes the longitudinal guide channel 51, the movable part 52, and the spring 53, which is easy to implement. After assembly, due to the action of the spring 53, the movable part 52 remains forward and sinks into the longitudinal guide channel 51 and is not easily separated from each other, so as to facilitate relative longitudinal guide movement and rotation transmission between the two. The first front-to-back connecting port 42 of the first transmission connection body 4 and the second front-to-back connecting port 60 of the second transmission connection body 6 are set, so that when the first transmission connection body 4 is removed from the rotating cylinder 2, the movable part 52 is manually pressed backward through the second front-to-back connecting port 60 and the first front-to-back connecting port 42 to move the movable part 52 backward away from the longitudinal guide channel 51 at the rear end of the first transmission connection body 4 and separate from each other. Finally, the first transmission connection body 4 is rotated relative to the rotating cylinder 2 to align it with the first limit inlet and outlet 221 and then removed, which is easy to disassemble.

[0036] like Figure 3 、 Figure 4 、 Figure 7 As shown, in a specific implementation, the second transmission connection structure includes a transverse accommodating groove 41 arranged at the front end of the first transmission connection member body 4, and the upper end wall and / or lower end wall of the transverse accommodating groove 41 are provided with a first transverse guide convex rail portion / first transverse guide groove portion 411, and the second transmission connection member body 6 is provided with a second transverse guide groove portion / second transverse guide convex rail portion 61 for transversely sliding and clamping connection with the first transverse guide convex rail portion / first transverse guide groove portion 411, and the second transverse guide groove portion / second transverse guide convex rail portion 61 of the second transmission connection member body 6 is a plurality of second transverse guide groove portions / second transverse guide convex rail portions 61 distributed front and back, and each of the second transverse guide groove portion / second transverse guide convex rail portion 61 can be detachably connected to the first transverse guide convex rail portion / first transverse guide groove portion 411 in a transverse guiding manner.

[0037] As described above, in this case, the transverse accommodating groove 41 of the first transmission connector body 4 is set, so that when the second transmission connector body 6 is connected to the first transmission connector body 4 for transverse guidance, the rear end of the second transmission connector body 6 can be accommodated in the transverse accommodating groove 41; the second transverse guide groove portion / second transverse guide convex rail portion 61 is set as a plurality of second transverse guide groove portions / second transverse guide convex rail portions 61 distributed front and back, which is convenient for specific implementation to select a certain second transverse guide groove portion / second transverse guide convex rail portion 61 and the first transverse guide convex rail portion / first transverse guide groove portion 411 for transverse guiding connection according to the front and rear position requirements of the second transmission connector body 6, which is convenient to implement and convenient to adjust the front and rear position of the second transmission connector body 6.
