Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1-6, the present embodiment provides an adjustable wrench, which includes a body, an adjusting handle disposed on the body; the body includes wrench head 1 and fixed handle 2 that sets up on wrench head 1, wrench head 1 cross section is annular hexagon, set up through-hole 3 on two or more sides of wrench head 1, adjustment handle and 3 cooperation settings of through-hole, the adjustment handle includes accommodate the lead screw 4, sets up the spacing slider 5 and the setting in accommodate the lead screw 4 middle section are in accommodate the lead screw 4 is last and be located the adjusting nut 6 in the wrench head 1 outside. The utility model discloses a rational design provides a spanner that can conveniently adjust, according to the size that is suitable for the nut, adjusts the position of regulation handle in the through-hole, and then adjusts the centre gripping scope size of spanner, makes it be applicable to the nut of equidimension not, and application scope is wide to it is convenient to adjust, has the preparation convenience, the characteristics of simple operation.

The one end that accommodate the lead screw 4 is located wrench head 1 inboard sets up spacing fixture block 7, set up the V-arrangement draw-in groove on the working face of spacing fixture block 7, spacing fixture block 7 mainly plays the effect of injecing and centre gripping the position of accommodate the lead screw 4, sets up the V-arrangement draw-in groove on the working face of spacing fixture block 7, cooperates the centre gripping with hexagon nut's angle and fixes, and is more stable to the centre gripping of nut.
