The radial tension spring 437b can enable the limiting elastic sheet 436 to be tightly attached to the swing guide sleeve 432, so that the limiting elastic sheet 436 can accurately slide into the position when the notch 431f slides out, and when the notch 431f slides into the swing guide sleeve 432, the limiting elastic sheet 436 can flexibly slide out of the notch 431f, so that the whole structure and principle are simple, and the action is reliable. In practical application, when the hinge position of the rear rod body 431b and the front rod body 431c is pushed to the outside of the swing guide sleeve 432, under the action of the pull force applied to the front rod body 431c by the return tension spring 437a, the front rod body 431c swings outwards around the hinge position relative to the rear rod body 431b, and can swing to a state that the inner included angle between the rear rod body 431b and the front rod body 431c is larger than 180 degrees, so that the avoidance range is enlarged, and the swing guide sleeve is simpler in structure and principle and sensitive and reliable in action. When the hinge position of the rear rod 431b and the front rod 431c is retracted into the swing guide 432, the return tension spring 437a is stretched to achieve the clamping. In practical application, through adjusting the opening angle between two claw rods 431, the clamping climbing of objects to be climbed of different specifications can be realized, and the application range is wider.
