[0037] Preferably, threaded holes are provided at both ends of the positioning plate 14, and the threaded sections 13 are connected to the inside of the threaded holes.

[0042] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0043] Working principle: hang the O-shaped lock 2 on the center ring on the back of the five-point harness, pass the arm through the strap 5, and wear the limit finger ring 7, then pull the restraint belt 8 to make the movable end of the restraint belt 8 pass around the arm, and stick the Velcro B surface 26 to the Velcro A surface 25, so that the strap 5 fits the arm more closely. After wearing it, you can grab the foot nails from the side when climbing the tower. Since the falling distance is short, there will be no excessive impact force when falling, so it can avoid personal injuries caused by low hanging and high use when the traditional safety belt is used incorrectly;

[0044] And any one of the transmission shafts 10 can be rotated, and in conjunction with the setting of the synchronous belt 12, the power of the transmission shaft 10 can be transmitted, so that the two transmission shafts 10 rotate at the same time, and in conjunction with the setting of the threaded section 13 with the opposite thread rotation direction, the two positioning plates 14 can be driven to move toward each other on the transmission shaft 10, so that the transmission shaft 10 is out of contact with the strap 5, and in conjunction with the connection between the guide shaft 15 and the guide groove 21, when the positioning plate 14 is displaced, the guide shaft 15 can be used to push the eccentric plate 20, because the eccentric plate 20 is supported by the support shaft 18, and then the support shaft 18 can be used to drive the stabilizing frame 19 to flip, so that the stabilizing frame 19 is away from the strap 5, thereby unlocking the strap 5;

[0045] Then pull the strap 5 to make it slide under the support of the limiting groove 4, and adjust the distance between the middle of the strap 5 and the assembly plate 1 to adapt to the use of people with different arm lengths. After the strap 5 is adjusted, rotate the transmission shaft 10 in the opposite direction to drive the two positioning plates 14 to approach each other, so as to cooperate with the top and bottom ends of the support box 9 to realize the positioning of the strap 5, and cooperate with the connection between the guide shaft 15 and the eccentric plate 20 to drive the stabilization frame 19 to flip, and position the two ends of the strap 5 at the top and bottom ends of the assembly plate 1 respectively.
