Abstract
The utility model relates to the technical field of the disassembling tool, in particular to a stretcher which disassembles a nut, which is provided with a backing ring, wherein a working bolt for disassembling the nut and a shifting ring for locking the nut are arranged inside the backing ring, the outer side of the shifting ring is engaged with a gear rotary device which is convenient to adjust, the gear rotary device comprises a gear base which is arranged on the backing ring, an intermediate gear which is arranged on the gear base and is engaged with the shifting ring and a rotary gear which is engaged with the intermediate gear, the rotary gear is provided with a wrench hole for a wrench to rotate the rotary gear, and an inner wrench is arranged inside the wrench hole to rotate so as to drive the rotary gear to rotate and to realize the adjustment of the gear rotary device, and the inner side of the backing ring is provided with a retainer ring for blocking the shifting ring. The stretcher has the advantages that the disassembling speed of the nut is improved, and the working efficiency is improved.
Description
Technical field
The utility model relates to the extracting tool technical field, especially a kind of stretcher that nut is carried out dismounting.
Background technology
At present, stretcher is widely used in the installation and the maintenance aspect of wind-powered electricity generation, boats and ships, big machinery etc., especially needs nut is removed and installed.In the prior art, operational procedure is that earlier cover is dialled circle, also will adjust according to nut location, makes to dial circle and aim at nut and be inserted in, and aims to dial the circle stopple and go into to dial rod again, as required, nut is locked or is unclamped, in such operating process.At first must determine to dial the accurate nut of snare, if do not put, can cause to dial and damage behind the circle pressurized and can't use, secondly, dial rod and fill in and dial rotation in the circle hole, also be subjected to the influence of surrounding environment size, the dismounting of nut is compared complexity, be to use driving lever nut is locked and to unclamp, the speed of dismounting is slower.
The utility model content
The technical problems to be solved in the utility model is: shortcoming and deficiency in order to solve above-mentioned existence provide a kind of stretcher that improves nut dismounting speed.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of stretcher, has the work bolt that is provided with the dismounting nut in gasket ring, the gasket ring and to the circle of dialling of nut check, dial the gear driving device that the outside of circle is connected with a joggle and is convenient to regulate, regulate group circle by the adjusting gear tumbler, realize the locking of nut or unclamp, then nut is carried out dismounting.
Further, for simple in structure, gear driving device comprises the gear base that is arranged on the gasket ring, be connected on the gear base and with the idler gear of dialling the circle engagement and with the swing pinion of idler gear engagement.
The adjusting gear tumbler offers on the swing pinion and is convenient to the driving hole that spanner rotates swing pinion for convenience, puts into driving hole by interior spanner and is rotated, the rotation of driven rotary gear, thereby the adjusting of realization gear driving device.
Fixing better for structure, the gasket ring inboard is provided with and stops the back-up ring of dialling circle.
For in the swing pinion tumbler, make to dial and enclose and can adjust the position automatically, be inserted in nut, dial the circle upper end and be provided with spring.
The beneficial effects of the utility model are that stretcher of the present utility model has improved the dismounting speed to nut, has improved the efficient of work.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Among the figure 1, gasket ring, 2, nut, 3, the work bolt, 4, spring, 5, dial circle, 6, gear driving device, 6-1, gear base, 6-2, idler gear, 6-3, swing pinion, 7, back-up ring.
The specific embodiment
In conjunction with the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
The stretcher of preferred forms as shown in Figure 1 and Figure 2, have work bolt 3 that is provided with dismounting nut 2 in gasket ring 1, the gasket ring 1 and group circle 5 that nut 2 is locked, dial the gear driving device 6 that the outside of circle 5 is connected with a joggle and is convenient to regulate, regulate group circle 5 by adjusting gear tumbler 6, realize the locking of nut 2 or unclamp, then nut 2 is carried out dismounting.
When the utility model is implemented, stretcher is stuck on the nut 2, rotate swing pinion 6-3 with the interior angle spanner, driving idler gear 6-2 is rotated, driven group circle 5 motions, made the spacing variation of dialling circle 5 and 2 on nut, as required, can lock and unclamp nut 2, improve the efficient of work.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
