The positioning rod 22 is connected with the control component, and the output shaft of the motor 71 is connected with the driving wheel 7. The driving wheel 7 is the power source of the device. The middle part of the driving wheel 7 is hollowed out. The frame 1 is connected with a power component, and the driving wheel 7 is connected to the power component. By keeping the driving wheel 7 rotating continuously in any direction, the power generated by the rotation of the driving wheel 7 is transmitted to the control component by the power component, thereby driving the reel 2 to rotate, and the rotation direction of the reel 2 is changed by the control component;

[0028] The power assembly includes a power wheel A5, which is frictionally connected to the outer wall of the driving wheel 7. The outer wall of the power wheel A5 is frictionally transmitted with the outer wall of the driving wheel 7. The driving wheel 7 rotates to drive the connected power wheel A5 to rotate in the opposite direction, thereby providing a force to the reel 2 in the opposite direction to the rotation direction of the driving wheel 7. The power wheel A5 is connected to a driving wheel A51. The axis of the power wheel A5 is colinearly arranged with the axis of the driving wheel A51. The driving wheel A51 is detachably connected to the control assembly. When the driving wheel A51 is connected to the control assembly, the selection direction of the driving wheel A51 is the same as that of the power wheel A5. The driving wheel A51 is used to drive the control assembly to rotate in the opposite direction to the power wheel A51, thereby making the reel 2 have the same rotation direction as the driving wheel 7.

[0029] The power assembly also includes a power wheel B6, which is frictionally connected to the inner wall of the driving wheel 7, and the outer wall of the power wheel B6 is frictionally transmitted to the inner wall of the driving wheel 7. When the driving wheel 7 rotates, the power wheel B6 connected thereto rotates in the opposite direction. A driving wheel B61 is connected to the power wheel B6, and the axis line of the power wheel B6 and the axis line of the driving wheel B61 are colinearly arranged. When the power wheel B6 rotates, the driving wheel B61 rotates in the same direction and at the same speed. The driving wheel B61 and the control assembly are detachably connected. When the driving wheel B61 is connected to the control assembly, the rotation direction of the reel 2 is opposite to the rotation direction of the driving wheel 7.

[0030] The control assembly includes a control wheel 31, which is slidably connected to the positioning rod 22 through a limiting hole 33, and the axis of the control wheel 31 is arranged in a colinear relationship with the axis of the positioning rod 22. The shape of the limiting hole 33 is the same as the shape of the combination of the positioning rod 22 and the two limiting columns 23. One end of the control wheel 31 is connected to a driven wheel A3, which is slidably connected to the positioning rod 22 through the limiting hole 33. The driven wheel A3 is detachably connected to the driving wheel B61. The other end of the control wheel 31 is symmetrically arranged. There is a driven wheel B32 identical to the driven wheel A3, and the driven wheel B32 is detachably connected to the driving wheel B61. By driving the control wheel 31 to move horizontally along the length direction on the positioning rod 22, the driven wheel A3 or the driven wheel B32 is brought into contact with or separated from the corresponding driving wheel A51 or driving wheel B61, so as to control the rotation direction of the reel 2; the positioning rod 22 is connected with an anti-slip plate 24, and the anti-slip plate 24 is used to shield the driven wheel A3 from falling off the positioning rod 22;

[0031] The control assembly also includes a limit clamp 4, on the inner wall of which a transmission ball 41 is symmetrically arranged. The transmission ball 41 rolls in the limit clamp 4, and the transmission ball 41 is connected to one end of the control wheel 31. The control wheel 31 rotates, which drives the connected transmission ball 41 to rotate, thereby reducing the friction between the transmission ball 41 and the control wheel 31, ensuring that pushing the limit clamp 4 to move in the horizontal direction can drive the control wheel 31 to move in the same direction, while reducing the friction between the control wheel 31 and the limit clamp 4;

[0032] The control assembly further includes a lead screw 43, one end of which is rotatably connected to the limit clamp 4, and the other end of which is threadedly connected to the slider 45. A locking plate 42 is connected inside the limit clamp 4. The distance between the limit clamp 4 and the slider 45 is changed by rotating the lead screw 43, so that the locking plate 42 fits with the rotating control wheel 31, and the control wheel 31 is frictionally locked by the locking plate 42.

[0033] A rubber pad is provided on one end of the locking plate 42 that contacts the control wheel 31, so as to increase the friction between the locking plate 42 and the control wheel 31 and improve the locking effect of the locking plate 42 on the control wheel 31;

[0034] The other end of the lead screw 43 is connected to a control unit 44, which is convenient for a worker to control the lead screw 43. Preferably, the control unit 44 is a disc.

[0035] The frame 1 is connected to a positioning plate 11, a slide groove 12 is provided in the positioning plate 11, a slider 45 is slidably connected in the slide groove 12, and the slider 45 moves horizontally along the length direction in the slide groove 12 to change in the same direction to control the movement of the limit clamp 4, thereby changing the rotation direction of the reel 2 or locking it. When the control wheel 31 needs to be locked, the slider 45 is moved horizontally to separate the driven wheel A3 and the driven wheel B32 from the driving wheel A51 and the driving wheel B61 respectively. The reel 2 rotates by inertia without a power source, and the locking plate 42 is used to lock the reel 2.
