[0060] Embodiment 3:

[0061] The difference from the above-mentioned Embodiment 2 is that, referring to Figures 1 - 8 , for the above-mentioned bandage 5, a buffer assembly 0 is provided on one side of the electric control box 1. The buffer assembly 0 is arranged between the winding roller 4 and the intercepting device 6. The buffer assembly 0 includes a round rod 01 and a movable rod 02. One side of the top of the support plate 7 is fixedly connected with a support plate 11.

Fixed plates 03 are fixedly connected to both ends of the outer surface of the movable rod 02. The round rod 01 is arranged at one end of the fixed plate 03 away from the movable rod 02. Both ends of the round rod 01 are fixedly connected to one end of the two fixed plates 03 respectively. The bandage 5 is arranged between the movable rod 02 and the round rod 01 and the top surface thereof is in contact with the outer surface of the round rod 01;

[0062] The buffer assembly 0 further includes two arc-shaped springs 04. An extension rod 05 is rotatably connected to the electric control box 1 through a bearing. One end of the extension rod 05 is fixedly connected to one end of the movable rod 02. A circular block 06 is fixedly connected to the outer circumference of the extension rod 05. An arc-shaped block 07 is fixedly connected to one side edge of the circular block 06. An arc-shaped groove 08 is opened on the inner wall of the electric control box 1. An arc-shaped shaft is fixedly connected in the arc-shaped groove 08. The arc-shaped block 07 is slidably arranged in the arc-shaped groove 08 and sleeved on the outer circumference of the arc-shaped shaft. The two arc-shaped springs 04 are respectively arranged on both sides of the arc-shaped block 07 and sleeved on the outer circumference of the arc-shaped shaft;

[0063] A driving member 09 is arranged between the buffer assembly 0 and the control assembly 3. The driving member 09 includes a plurality of movable blocks 091 and a rotating block 092. A rotating rod 093 is rotatably connected to the inner wall of the electric control box 1 through a bearing. A driving belt 094 is sleeved on the outer periphery of the connecting rod 32 and the rotating rod 093. The plurality of movable blocks 091 are evenly and fixedly distributed on the outer periphery of the driving belt 094. The rotating block 092 is fixedly arranged on the outer periphery of the extension rod 05. One side of the movable block 091 abuts against one side of the rotating block 092.

[0064] Specifically, the driving motor 31 drives the connecting rod 32 and the load-bearing roller 2 fixedly connected to the connecting rod 32 to rotate, thereby driving the winding roller 4 to wind the bandage 5. During the process of the winding roller 4 winding the bandage 5, through the sleeving between the connecting rod 32, the rotating rod 093 and the driving belt 094, when the connecting rod 32 rotates, it drives the driving belt 094 to rotate, thereby driving the movable block 091 to rotate synchronously with the driving belt 094. Through the arrangement that one side of the movable block 091 abuts against one side of the rotating block 092, when the movable block 091 rotates, it drives the rotating block 092 to rotate by a certain angle, thereby causing the circular block 06 and the extension rod 05 fixedly connected to the circular block 06 to rotate by a certain angle, and further driving the movable rod 02 fixedly connected to the extension rod 05 to rotate. Through the arrangement that both ends of the fixing plate 03 are respectively fixedly connected to the movable rod 02 and the round rod 01, when the movable rod 02 rotates, it drives the round rod 01 to rotate by a certain angle. At this time, the arc-shaped spring 04 in the arc-shaped groove 08 is compressed. When the movable block 091 disengages from the rotating block 092, the arc-shaped spring 04 restores its elasticity, thereby driving the arc-shaped block 07 to reset, and causing the extension rod 05 and the movable rod 02 fixedly connected to the extension rod 05 to reset, thereby causing the round rod 01 to reset, and further causing the round rod 01 to rotate up and down repeatedly within a certain angle. During the process of the winding roller 4 winding the bandage 5, the reciprocating movement of the round rod 01 gives the bandage 5 an adaptive tension, avoiding the problem that during the winding process of the winding roller 4 on the bandage 5, the winding roller 4 gives the bandage 5 a high-intensity tension, which may cause the bandage 5 to break.
