[0023] A driving wheel 3 and a driven wheel 4 are oppositely arranged on the outer circumferential surface, the shaft end surface is parallel to the first connecting plate 1, and a wire groove 18 is formed on the outer circumferential surface of the driving wheel 3 and the driven wheel 4, the driving wheel 3 is connected and driven by a first steering engine 5, a strip-shaped groove 6 is formed on the first connecting plate 1 and the second connecting plate 2, the driven wheel 4 is arranged on a wheel shaft 7, the wheel shaft 7 is arranged in the strip-shaped groove 6 to form a sliding connection, a driving sliding block 8 is further arranged in the strip-shaped groove 6, a compression spring 9 is arranged between the driving sliding block 8 and the wheel shaft 7, the driving sliding block 8 is driven to move towards the wheel shaft 7 by a second steering engine 10, so as to change the pressure of the compression spring 9 on the wheel shaft 7.

[0024] The first steering engine 5 is fixed on the first connecting plate 1, and a steering disc 12 is fixed on the driving end of the first steering engine 5, and the steering disc 12 is fixed with the shaft end surface of the driving wheel 3.

[0025] Both ends of the wheel shaft 7 pass through the strip-shaped groove 6 and are arranged in the stepped structure limiting in the strip-shaped groove 6, the driven wheel 4 is arranged on the wheel shaft 7 through a bearing 13, and the wheel shaft 7 is axially limited by a sleeve shaft block 14 arranged at both ends in the axial direction, the part of the wheel shaft 7 protruding from the first connecting plate 1 and the second connecting plate 2 is provided with a protruding structure for sleeving the compression spring 9, both ends of the driving sliding block 8 pass through the first connecting plate 1 and the second connecting plate 2 and are limited by the stepped structure, and the parts of both ends of the driving sliding block 8 protruding from the first connecting plate 1 and the second connecting plate 2 correspond to and are connected with the compression spring 9 to form elastic extrusion on the wheel shaft 7.

[0026] The second steering engine 10 is arranged on the first connecting plate 1, and a rocker arm 15 is connected to the driving end of the second steering engine 10, the driving sliding block 8 is located on the rotation path of the rocker arm 15, and the driving sliding block 8 is driven to slide in the strip-shaped groove 6 by rotating the rocker arm 15.

[0027] The wire grooves 18 on the outer circumferences of the driving wheel 3 and the driven wheel 4 are combined to form a wire clamping structure for the parachute rope to pass through, guide plates 16 are arranged on both sides of the wire groove combination position, guide holes 17 are arranged on the corresponding positions of the guide plates 16, and the upper end and the lower end of each guide plate 16 are respectively connected and fixed with the first connecting plate 1 and the second connecting plate 2.

[0028] When operating:

[0029] The umbrella rope is inserted into the guide hole 17 of the upper guide plate 16, ensuring that the umbrella rope is placed flat without twisting or knotting. Then, the umbrella rope is placed in the wire slot of the driving wheel 3 and the driven wheel 4, and the pre-tightening force of the compression spring 9 is used to press the umbrella rope tightly. In this way, the umbrella rope is stably clamped between the two wheels. The umbrella rope is then fixed by being inserted out of the guide hole 17 on the other side, and the two guide plates 16 work together to ensure that the position of the umbrella rope between the driving wheel 3 and the driven wheel 4 is accurate and cannot deviate or slide, so that the umbrella rope can be firmly fixed, providing a stable basis for subsequent tension adjustment.

[0030] When the umbrella rope is fixed, the first steering engine 5 is started to make the driving wheel 3 rotate continuously. Because there is a certain pressure between the driving wheel 3 and the driven wheel 4, the driven wheel 4 will rotate in the opposite direction, and at this time the umbrella rope pressed tightly by the two wheels will generate a certain tension. Next, the second steering engine 10 is started, and the angle of the rocker arm 15 is adjusted to change the position of the driving block 8. The change in the position of the driving block 8 will directly affect the pushing force of the compression spring 9 on the wheel shaft 7, thereby changing the pressure of the two wheels on the umbrella rope. With the change in pressure, the tension of the umbrella rope will also change accordingly. By changing the rotation angle of the second steering engine 10, the tension of the umbrella rope can be flexibly adjusted. This adaptive adjustment method can ensure that the umbrella rope always remains within the appropriate tension range according to different working environments and requirements. Through the use of the above structure, precise control of the tension of the umbrella rope can be achieved, ensuring the stability and safety of the umbrella rope during movement.
