Abstract

The utility model discloses an adjustable spanner, including handle, fixed clamp splice, activity clamp splice, fixed clamp splice and handle are as an organic whole, are equipped with the hexagon trepanning on the fixed clamp splice, are equipped with spout, worm wheel on the handle, are equipped with movable clamp splice in the spout, are equipped with the screw on the activity clamp splice, screw thread and worm wheel interlock. This spanner simple structure, convenient operation, utilization have fixed clamp splice and a movable clamp splice of certain angle, make it when the wrench movement nut, make three times even atresss on the nut, reduce to turn round the probability of decreasing the nut edges and corners, but the hexagonal triangle nut of the multiple specification variation in size of wrench movement.

Description

Adjustable wrench
Technical field this utility model relates to hardware & tools field, is specifically related to a kind of adjustable wrench.
Background technology spanner is a kind of conventional to be installed on extracting tool, utilizes lever principle to twist the hand tools of bolt, nut and other opening spelling tight bolt or nut with screw thread or trepanning firmware. Relatively common has adjustable wrench, fork spanner, double offset ring spanner and box spanner etc. Dividing from its force turning hex nut, common wrench and fork spanner are all that torsion is applied on two planes of symmetry of hex nut, firmly slightly larger, it is easy to the corner angle of nut are twisted deformation and damages nut; Double offset ring spanner and box spanner are that torsion is applied on six faces of nut, but this type of instrument is all the combination of set of external member, and in using and depositing, careless slightly very easily single-piece is lost, and make the external member of the whole series use inconvenience.
Summary of the invention is for overcoming above-mentioned deficiency, and this utility model provides the adjustable wrench making hex nut three limit stress.
This utility model solves its technical problem and the technical scheme is that
A kind of adjustable wrench, including handle, fixing fixture block, movable clip block, described fixing fixture block and what handle was integrated, fixing fixture block is provided with hexagon trepanning, and handle is provided with chute, worm gear, is provided with movable clip block in chute, movable clip block is provided with screw thread, and described screw thread is engaged with worm gear.
Six angles of described hexagon trepanning are 120 ��, and the angle of the extended line on its a limit and b limit is 60 ��.
It is rectangular chute that the front end of described handle is provided with cross section.
The beneficial effects of the utility model: simple in construction, the fixing fixture block that easy to operate, utilization has certain angle and a movable clip block, make it when twisting nut, make three times uniform stresseds of nut, reduce and turn round the probability damaging nut corner angle, the hexagonal triangle nut that plurality of specifications varies in size can be twisted.
Description of drawings 1 is structural representation of the present utility model;
Fig. 2 is structural representation during this utility model use;
The side sectional view of the present utility model of Fig. 3;
1, hands handle; 2, worm gear; 3, movable clip block; 4, fixing fixture block; 5, nut.
Detailed description of the invention one adjustable wrench, including handle 1, fixing fixture block 4, movable clip block 3, described fixing fixture block 4 and what handle 1 was integrated, fixing fixture block 4 is provided with hexagon trepanning, and it is rectangular chute that the front end of handle 1 is provided with cross section, movable clip block 3 it is provided with in chute, movable clip block 3 is provided with screw thread, owing to screw thread is engaged with worm gear 2, during use, make it rotate to move movable clip block 3, reach the purpose of binding nut by stirring worm gear 2.The a limit of hexagon trepanning, b limit and the clamping mode of the c limit composition equilateral triangle of movable clip block 3, reach the purpose to six limit nut three limit stress during twisting handle.
It is simple that adjustable wrench compares common wrench, fork spanner and plum wrench structure, easy to operate.
