Abstract
A nut wrench capable of avoiding or reducing nut edge angle pile-up is composed of an upper wrench head with arc opening and arc opening, a lower wrench head with clamping edge, and a wrench handle with clamping edge.
Description
The utility model relates to the instrument of pulling nut, is a kind of nut spanner.
Existing nut spanner formation has generally comprised spanner, following spanner and trigger piece, since last spanner pull mouthful and pulling of following spanner mouthful all be to put down mouth, thereby when pulling nut, active force mainly concentrates on the corner angle of nut, thereby easily the corner angle of nut are twisted heap and nut is damaged, cause with nut spanner and can't pull nut again.
In view of the problem of above-mentioned existence, the purpose of this utility model is to design a kind ofly to be avoided or reduces the nut spanner of the nut corner angle being twisted heap.
The purpose of this utility model realizes by following measures: this nut spanner comprises upper spanner, lower spanner and trigger piece, and mouthful projection and curved of pulling of pulling mouth and lower spanner of upper spanner; Pulling of upper spanner has the card rib on the mouth; Pulling of lower spanner has the card rib on the mouth.
Accompanying drawing is the structural representation of the utility model most preferred embodiment and uses state diagram;
Coding in the accompanying drawing is respectively: 1 is upper spanner, and 2 is lower spanner, and 3 is trigger piece, and 4 for pulling mouth, and 5 is nut, and 6 is corner angle.
Below in conjunction with most preferred embodiment and accompanying drawing the utility model is further described:
As shown in drawings, this most preferred embodiment comprises spanner 1, lower spanner 2 and trigger piece 3, and mouthful 4 projections and curved of pulling of pulling mouth 4 and lower spanner 2 of upper spanner 1;
For the ease of blocking nut, pulling of upper spanner has the card rib on the mouth, perhaps descends pulling of spanner that the card rib is arranged on the mouth.
When using the utility model: since upper spanner 1 pull mouthfuls 4 and lower spanner 2 to pull mouthful 4 projections curved, like this when pulling nut 5 with this nut spanner, active force just is not concentrated on the corner angle 6 of nut 5, thereby just be not easy the corner angle 6 of nut 5 are twisted heap, so also be not easy to damage nut 5.
The utility model manufacturing simple in structure, easy utilizes this nut spanner effectively to avoid or to reduce the nut corner angle is twisted heap, thereby also effectively avoids or reduced damage to nut.
