Abstract

The utility model relates to a hexagon wrench, which is characterized in that a clamping opening of the wrench is composed of an edging a, an edging b, an edging c, an edging d, an edging e and an edging f. When a nut is screwed, people wrench the wrench clockwise; the edging a, the edging b, the edging c and the edging d of the clamping opening are tightly engaged with a hexagonal nut to drive the nut to rotate following the wrench. Then, people wrench the wrench counterclockwise for preparing to screw the nut again, and the edges of the hexagonal nut slide along the edging an of the clamping opening; the edging a, the edging b, the edging c and the edging d of the clamping opening are separated from the hexagonal nut, and the nut do not rotate following with the wrench. People wrench the wrench clockwise again, and the nut can be screwed again. The hexagon wrench can continuously screw nuts like a ratchet wrench.

Description

Hexagon wrench

The utility model relates to a kind of spanner that is used to turn hex nut, bolt.

At present, turn hex nut, bolt and usually use common die nut; The bayonet socket of the spanner of common die nut is the U-shaped bayonet socket, relies on two parallel edges of U-shaped bayonet socket to be meshed with hex nut or bolt head, turns nut or bolt by pulling the spanner handle.When using common die nut repeatedly to turn hex nut, need repeatedly take out out die nut, make its U-shaped bayonet socket can realize repeatedly turning with the hex nut engagement beginning again.Therefore, use this common die nut to turn nut and often make us feeling inconvenient.

The purpose of this utility model is to provide a kind of novel die nut, when using this spanner to turn hex nut or bolt, need not take out out spanner repeatedly and realizes turning continuously, and this spanner has the same function that turns nut continuously of ratchet spanner.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a use schematic diagram of the present utility model.

Below in conjunction with accompanying drawing the utility model is described in detail.

Referring to Fig. 1, the utility model is the same with common die nut, and it is made up of spanner with bayonet socket (1) (2) and spanner handle (3), and its technical characterictic is that bayonet socket (1) is made of the angle α on a limit and b limit a, b, c, d, e, f limit ₁Be 108 °, the angle α on b limit and c limit ₂Be 120 °, the angle α on c limit and d limit ₃Be 120 °, the angle α on e limit and f limit ₄Be 120 °, the opposite side distance that the length on b limit equals corresponding hex nut is from 0.496 times of S, and the length on c limit equals every edge lengths of corresponding hex nut, and the length on d limit is half of every edge lengths of corresponding hex nut, and the f limit play the guiding role.

Sketch use principle of the present utility model below in conjunction with accompanying drawing.

When using the utility model fastening nut, referring to Fig. 2 it (I), after the bayonet socket of spanner stuck hex nut, pull spanner clockwise, three limit tight engagement of the b of spanner bayonet socket, c, d limit and hex nut, another limit of hex nut is lived in a checkpost of bayonet socket, and hex nut is just along with spanner clockwise rotates.Then, referring to Fig. 2 it (II), inhour is pulled spanner, for fastening nut is once more prepared, at this moment, the edge of hex nut slides along a limit of bayonet socket, the b of bayonet socket, c, d limit just break away from engagement with hex nut, and hex nut can not made inhour with spanner and rotate.Referring to Fig. 2 it (III), when bayonet socket a limit contacts next bar limit of nut in turn, pull spanner, make it to do to clockwise rotate for the second time, the b of bayonet socket, c, d limit once more with the hex nut tight engagement, nut is just done to turn clockwise for the second time with spanner.Repeat said process, until till with nut screwing clamping.

Advantage of the present utility model is repeatedly to take out out spanner, and---counterclockwise---the clockwise spanner of pulling can realize repeatedly turning nut clockwise as long as carry out repeatedly.The same nutting continuously with ratchet spanner of this spanner, its manufacturing cost is than ratchet spanner much less.

Claims

A kind of die nut, it comprises the have bayonet socket spanner [2] and the handle [3] of [1], it is characterized in that bayonet socket [1] is made of the angle α on a limit and b limit a, b, c, d, e, f limit ₁Be 108 °, the angle α on b limit and c limit ₂Be 120 °, the angle α on c limit and d limit ₃Be 120 °, the angle on e limit and f limit is 120 °, and the opposite side distance that the length on b limit equals corresponding hex nut is from 0.496 times of S, and the length on c limit equals every edge lengths of corresponding hex nut, and the length on d limit is half of every edge lengths of corresponding hex nut.
