Abstract
The utility model relates to a kind of adjustable movable liner head that is applied to box spanner, comprise that one in order to be connected to the adapter sleeve on socket bar, it is characterized in that: in described adapter sleeve, be bolted with a fixed cover, the perimembranous of described fixed cover is provided with a circle in order to be connected to the movable apical grafting piece for the treatment of on operation nut, and described movable apical grafting piece becomes plane and is uniformly distributed.The utility model simple structure, it is convenient to realize, and can adapt to multiple nut model, can improve service work efficiency thereby saved frequently with changing collet head.
Description
Technical field
The utility model relates to a kind of adjustable movable liner head that is applied to box spanner, is applied to substation equipment maintenance and repair.
Background technology
Existing sleeve, is a socket bar, the collet head of corresponding multiple different sizes.
According to actual service work experience, staff often has on 500Kv and 220Kv disconnecting link framework and works, duty cycle is long, working face is high, and the fastening screw nut model of various disconnecting links is inconsistent, sometimes there will be, the model of collet head and nut is inconsistent, need to repeatedly change, or pass to work high above the ground personnel by ground staff with rope.And sometimes maintainer in elasticity bolt, often needs the collet head of various models all to take on high-altitude on high-altitude, increase the heavy burden of work, also reduce operating efficiency.Therefore, for the problems referred to above be the object of the utility model research.
Utility model content
In view of the deficiencies in the prior art, the purpose of this utility model is to provide a kind of adjustable movable liner head that is applied to box spanner, contributes to solve existing collet head model various, carries the problems such as inconvenience.
The technical solution of the utility model is:
A kind of adjustable movable liner head that is applied to box spanner, comprise that one in order to be connected to the adapter sleeve on socket bar, it is characterized in that: in described adapter sleeve, be bolted with a fixed cover, the perimembranous of described fixed cover is provided with a circle in order to be connected to the movable apical grafting piece for the treatment of on operation nut, and described movable apical grafting piece becomes plane and is uniformly distributed.
Wherein, described fixed cover cylindrical structural, described adapter sleeve is bell-mouth structure of air.
Described adapter sleeve and socket bar connecting portion are square groove structure.
Described movable apical grafting piece is 6.
The utility model has the advantage of: the utility model simple structure, it is convenient to realize, and can adapt to multiple nut model, can improve service work efficiency thereby saved frequently with changing collet head.
Brief description of the drawings

Fig. 2 the utility model embodiment perspective view two.
Detailed description of the invention
For above-mentioned feature and advantage of the present utility model can be become apparent, special embodiment below, and coordinate accompanying drawing, be described in detail below.
Referring to figs. 1 to Fig. 2, the utility model relates to a kind of adjustable movable liner head that is applied to box spanner, comprise that one in order to be connected to the adapter sleeve 1 on socket bar, in described adapter sleeve, be bolted with a fixed cover 2, the perimembranous of described fixed cover is provided with a circle in order to be connected to the movable apical grafting piece 3 for the treatment of on operation nut, and described movable apical grafting piece becomes plane and is uniformly distributed.
Above-mentioned fixed cover cylindrical structural, described adapter sleeve is bell-mouth structure of air.
Above-mentioned adapter sleeve and socket bar connecting portion are square groove structure 4.
Above-mentioned movable apical grafting piece is 6.
In implementation process, according to the contour structures of operation nut, adjust the spacing between fixed cover and adapter sleeve, thereby the outer wall promotion activity apical grafting piece of adapter sleeve is moved, treating in the periphery of operation nut until movable apical grafting piece is stuck, then utilizing socket bar to be installed in square groove, utilize the rotation of socket bar that nut is dismantled.This collet head can carry out operation according to the nut of different size, adapts to wide.
The foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
