The stabilizing sleeve 1 is combined on the inserting rod 2, and the inserting rod 2 is distributed in the telescopic slot 19-1 in a lifting mode, namely the adjusting screw rod 20 is adjusted to lift to support the inserting rod 2, so that the vertical height adjustment is achieved, and the application range is wider and more flexible. The other two brackets of the stabilizing bracket 19 are provided with tightening holes 19-2 for tightening and fixing on a fixed frame or the ground. The stable sleeve 1 is sleeved outside the bolt sleeve body 3 and supports and limits the bolt sleeve body; the inner cavity of the stable sleeve 1 is also provided with limiting convex rings 1-2, and the limiting convex rings 1-2 are distributed between the bolt sleeve body 3 and the twisting sleeve 4; the bolt sleeve body 3 is distributed in front of the limiting convex ring and can freely move for 2-5 mm in the axial direction, and a vacant position 1-1-1 is reserved. The front part of the bolt sleeve body 3 is provided with a bolt sleeve opening 3-2, the depth of the bolt sleeve opening 3-2 is longer than the thickness of a bolt head of a bolt to be disassembled, the rear part of the bolt sleeve opening is provided with a connecting tooth 3-1, and the embodiment adopts gear-shaped tooth marks; the front part of the twisting sleeve 4 is provided with twisting teeth matched with the connecting teeth; the sleeve 4 that twists passes through the tooth that twists corresponds and distributes the rear of the bolt cover body 3, just sleeve 4 that twists is relative the bolt cover body 3 can freely break away from, make up. Wrench movement sleeve 4 combines through T shape nail 13 the rear of the bolt housing body 3, just it has extrusion spring 14 to distribute on the T shape nail 13, and is right always wrench movement sleeve 4's rear portion extrudees, for the better reversal operation of wrench movement sleeve 4 when realizing the operation, the extrusion spring 14 both ends of this embodiment respectively are equipped with rotation pressure disk gasket 10 and rotation pressure disk gasket 12. In this embodiment, in order to facilitate the operations of separating and combining the twisting sleeve 4 with respect to the bolt bushing body 3, an elastic push rod assembly is further provided, and the elastic push rod assembly includes a return spring 5, a push block 9 and a rotating rod 16; the ejector pad 9 is movably distributed in ejector pad activity groove 6 that is seted up in the left and right sides of wrench movement sleeve 4, simultaneously, for promoting, ejector pad 9 rear portion still is equipped with lug 8, and ejector pad activity groove 6 corresponds has seted up lug export 7, and lug 8 stretches out from lug export 7. The rotating rod 16 is distributed in the twisting rod 18, meanwhile, a left supporting arm 15 and a right supporting arm 15 are arranged on the upper portion of the rotating rod 16, and the left supporting arm 15 and the right supporting arm 15 penetrate out of a supporting arm arc-shaped opening 18-1 of the twisting rod 18 and are in contact with the bump 8.
