Embodiment approach

[0030] like figure 1 As shown, a spring screw sleeve for removing screw nuts is characterized in that it includes a sleeve 1, a chute 2 arranged on the sleeve 1, and a sliding groove 2 provided in the chute 2. A fixed clip 3; one end of the first spring 4 is fixed on one end of the chute 2, and the other end is fixed on the fixed clip 3. The chute 2 is arranged along the radial direction of the sleeve 1 .

[0031] like figure 2 As shown, the fixed clip 3 includes a fixed clip sleeve 301 arranged in the chute 2, the middle part of the fixed clip sleeve 301 is provided with a vertical threaded through hole, and the second spring 304 is arranged on the In the threaded through hole; the bolt 302 is arranged on the upper part of the threaded through hole and connected with the upper end of the second spring 304 , and the buckle 303 is arranged at the lower part of the threaded through hole and connected with the lower end of the second spring 304 . The slider 3011 is in the sha...

Abstract

The invention discloses a spring screw sleeve and a method for dismantling a screw nut. The spring screw sleeve includes a sleeve, a chute arranged on the sleeve, and a sliding groove arranged in the chute. A fixed clip; one end of the first spring is fixed on one end of the chute, and the other end is fixed on the fixed clip. In the present invention, the screw that needs to be disassembled is covered by the sleeve, and the fixed clip is moved to compress the first spring, press the screw, and apply an outward pulling force to the screw and the nut to be removed, and the pulling force acting on the nut is converted into the nut and the spacer The frictional force restricts the rotation of the nut with the screw; thereby solving the problem that the nut cannot be fixed in the near-electrical part or narrow part in the traditional work, causing the nut to rotate with the rotation of the screw, and realizes the single-person disassembly of various near-electrical or narrow areas. The work of screws and nuts improves work efficiency.

Description

technical field [0001] The invention belongs to the technical field of electric equipment, and in particular relates to a spring screw sleeve and a method for removing screw nuts. Background technique [0002] At present, the installation of all kinds of electrical equipment is mostly fixed with screws and nuts. When the equipment is running with electricity, the surrounding is adjacent to the live conductor or the position of the nut cannot be touched, simply screwing the screw often causes the nut to rotate with the screw, and the nut cannot be removed. Now generally use insulating gloves method or blackout operation method for disassembly. [0003] Insulating gloves method: Two people operate, one person wears insulating gloves or wears a full set of insulating protective equipment, holds the nut by hand or fixes the nut with tools, and the other person twists the screw to achieve the purpose of removing the screw and nut; but this method requires two People carry out op...
