Compared with the external clutch mechanism 5, the transmission between the motor 3 and the clutch mechanism 5 is more stable. In addition, when workers install the entire set of structures in the winding tube, they do not need to install the clutch structure separately, which reduces the process time.

[0029] The clutch mechanism 5 may be an electromagnetic clutch.

[0030] Reference Figure 2 and Figure 3 As shown, at least one first silicone member 11 is disposed between the inner tube 2 and the outer tube 1, wherein an annular groove is provided on the inner tube 2, and the first silicone member 11 is annular and sleeved on the annular groove;

[0031] Preferably, two annular grooves are provided and are respectively located at both ends of the inner tube 2, thereby increasing the connection stability between the inner tube 2 and the outer tube 1;

[0032] A plurality of protrusions are formed on the outer ring of the first silicone member 11 . The protrusions are evenly distributed along the circumference of the first silicone member 11 , thereby achieving a shock-absorbing effect when the motor 3 is working.

[0033] Reference Figure 3 As shown, a fixing member 12 is connected to the end of the outer tube 1, and the fixing member 12 is plugged into the outer tube 1. A plurality of clamping blocks are formed on the fixing member 12, and the clamping blocks are evenly distributed along the circumference of the fixing member 12. A plurality of clamping grooves are opened at the end of the outer tube 1, and the clamping blocks are plugged into the corresponding clamping grooves to form a connection between the fixing member 12 and the outer tube 1; the output end of the output member 4 exposes the fixing member 12 and is rotatably connected to the fixing member 12, so that when the output member 4 rotates, the fixing member 12 does not rotate.

[0034] Reference Figure 2 As shown, at least one first bearing 13 is connected inside the fixing member 12, and the fixing member 12 is rotatably connected to the output member 4 through the first bearing 13. The provision of the first bearing 13 increases the stability of the output member 4 during rotation;

[0035] Preferably, two first bearings 13 are provided;

[0036] Reference Figure 8 As shown, the output member 4 includes an output column and an output platform, wherein the output column and the output platform can be integrally formed or can be separately detachably arranged, a positioning cavity is opened at the end of the fixing member 12 facing the motor 3, the output platform is at least partially located in the positioning cavity, a first installation cavity is formed at the inner end of the positioning cavity, a first bearing 13 is installed in the first installation cavity, and a second installation cavity is formed at the end of the fixing member 12 away from the motor 3, another first bearing 13 is installed in the second installation cavity.
