Abstract
The utility model relates to a pair of special pliers for dissembling a small nut, and belongs to the technical field of hand tools. The technical scheme is as follows: the special pliers comprise two pliers arms hinged in the middle, wherein the part of each pliers arm positioned at the back of a hinge shaft is a pliers handle, and the part, positioned at the front of the hinge shaft, of each pliers arm is a pliers head; and the front ends of the pliers heads of the two pliers arms oppositely bend to become flat plates vertical to the pliers arms, and openings are arranged in the butting edges of the two flat plates and butted to from a regular polygon. The small nut is tightly clamped by the openings at the front ends of the two pliers arms, and is dissembled or tightened by rotating the pliers handles, accordingly, the defects that a pair of nipper pliers easily slips when clamping the small nut are overcome, and the required operation space is small. The special pliers is especially suitable for dissembling the small nut on a dense terminal, and the maintenance efficiency of substation equipment and instrumentation is greatly improved.
Description
Technical field
The utility model relates to a kind of pliers that is specifically designed to the primary nut on dismounting instrument, instrument, belongs to the hand-operated tools technical field.
Background technology
To the various relays of transformer station, when instrument is overhauled, need a large amount of primary nut of dismounting, owing to there is no at present the special-purpose small tool of this kind, generally dismantle these primary nuts with nipper plier or spanner in maintenance process, the very little very light of the front end of nipper plier, be easy to skid during the clamping primary nut, and spanner need to there be larger operating space, can't uses during than comparatively dense when binding post at all.Therefore, utilize existing instrument dismounting primary nut very inconvenient, greatly reduce the overhaul efficiency of instrument, instrument.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of primary nut dismounting special vice is provided, to improve the overhaul efficiency of the various relays of transformer station, instrument.
The purpose of this utility model realizes with following technical proposals:
A kind of primary nut dismounting special vice, formation comprises two tong arms that the middle part is hinged, the part that each tong arm is positioned at the jointed shaft back is clamp handle, the part that is positioned at the jointed shaft front is binding clip, the front end of the binding clip of two tong arms bends in opposite directions and becomes flat board perpendicular to tong arm, be provided with gap on the butt joint edge of two flat boards, the gap of two flat boards is to being connected into regular polygon.
Above-mentioned primary nut dismounting special vice, the gap of two tong arm front end flat boards is the V-type gap, they are square to the regular polygon that is connected into.
Above-mentioned primary nut dismounting special vice, the clamp handle outer setting of described tong arm has insulation sleeve.
The utility model utilizes the gap of two pincers wall front ends that primary nut is tightened, then dismantle or tighten primary nut by the rotation clamp handle, it has overcome the deficiency that nipper plier clamping primary nut easily skids, and required operating space is little, be particularly suitable for the primary nut on the intensive binding post of dismounting, greatly improved the overhaul efficiency of transformer station's instrument, instrument.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present utility model.
The specific embodiment
In figure, each label is: 1, jointed shaft; 2, tong arm; 3, gap; 4, insulation sleeve.
Referring to Fig. 1, the utility model comprises two tong arms 2, both links together by jointed shaft 1, and the rear portion of two tong arms 2 is clamp handle, and on clamp handle, cover has insulation sleeve 4.The front portion of two tong arms 2 is for being used for the binding clip of clamping primary nut, binding clip front end of the present utility model is spent and is tabular to jaw inner bending 90, the butt joint edge place of two tong arm front end flat boards is provided with V-type gap 3, two V-type gap 3 docking quadrates, this structure not only can tighten primary nut, prevents from skidding in operating process, and is applicable to the primary nut of different size, make the dismounting of primary nut very convenient, quick, thereby improved the overhaul efficiency of transformer station instrument, instrument.
