The moving wheel 1100 is a rubber wheel with a diameter of 15 cm to 30 cm, so that the moving is convenient and fast, and the carrying is convenient. The movable clamping jaws 130 are made of circular steel plates with the thickness of 2mm to 5mm, so that the contact area can be enlarged, and the fixation is stable and reliable. The height of the tension wheel 510 is 1 cm to 4 cm higher than the installation height of the pulley set 600, which is beneficial to converting the cable tension into the pressure of the tension detection device 500 and is convenient for accurately controlling the cable tension.

The specific working principle is as follows:

the distance between the movable jaw 130 and the fixed jaw 140 is moved by rotating the fixed handwheel 1200 through the lead screw 150, so that the base 200 is fixed on the accessory; when the cable passes through the tension wheel 510, downward pressure is generated on the wheel shaft, the greater the tension force is, the greater the pressure is, a signal is transmitted to the driving motor 1000 through the tension alarm 550, and the movement of the driving motor 1000 is controlled.

It is understood that the spacing may also be 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, etc.

In addition to the above preferred embodiments, the technical solutions protected by the present invention are not limited to the above embodiments, and it should be noted that the combination of the technical solution of any one embodiment and the technical solution of one or more other embodiments is within the scope of the present invention. Although the invention has been described in detail with respect to the general description and the specific embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made based on the invention. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
