Description
Technical Field
The utility model relates to a wrench, in particular to a wrench which can enable double nuts to be locked quickly.
Background
In the industrial production practice, bolts and nuts are common mechanical connecting fasteners, and in order to maintain constant clamping force or keep the nut and the bolt head at a stable distance, people often need the nut to be fixed and stopped at a certain position of the bolt for a long time without easy displacement, which involves a problem of nut locking.
In the prior art, there are many ways of nut locking, but the most economical and simple way is the double nut locking. The main principle and method of this approach are: the first nut is screwed to a target position from the tail part of the bolt, then the second nut is screwed from the tail part of the bolt, when the two nuts are close to each other, the position of the first nut is kept still, and the second nut is screwed to be close to the first nut, so that axial force is generated between the nuts, friction force between nut teeth and bolt teeth is increased, and the purpose of preventing the nuts from loosening automatically is achieved.
In production practice, people often screw nuts with a common open-end or trepan-boring wrench, and the common wrench can only screw one nut at a time, so that the situation that one nut is rotated to drive the other nut to rotate together often occurs, and the locking effect cannot be achieved. If two wrenches are used for operation, two hands are required to cooperate to exert force, and people often cannot complete the action of screwing the two hands due to high-altitude operation, narrow space or holding of an object by the other hand. In practice, still often meet the condition such as the size nonconformity of different mechanical position nuts, the staff need carry the spanner of a large amount of different models to carry out the operation, and a plurality of spanners not only weight is heavy still inconvenient to be carried, has increased the intensity and the degree of difficulty of operation, has reduced work efficiency, if the spanner loses the hand landing, still can cause to pick up the difficulty and cause the safety risk.
Therefore, the double-nut locking wrench is developed, two nuts can be clamped simultaneously, the screwing and locking process is completed, the wrench can be operated by one hand, the working efficiency is improved, and the market blank is filled.
