Abstract
The utility model relates to an adjustable wrench, which comprises three working surfaces A, B and C, forming two 120-degree angles e and f on a fixed clamping seat 3; a movable clamping block 5 is provided with a working surface D, which forms an 120-degree included angle with the adjacent working surface A on the fixed clamping seat 3; the angle between the halfway line m of a handle arranged on the same plane and the jaw halfway line n is 25 to 85 degrees; as for the fastener in the application scope of the wrench, the wrench can ensure at least three working surfaces attached on the fastener, so as to effectively prevent the fastener from relative sliding or falling during operation, avoid damage to the fastener and prevent the wrench from falling off and hurting people during working aloft.
Description
The utility model belongs to a kind of instrument, particularly relates to a kind of manual fastened tools.
Existing monkey wrench comprise handle, handle one end fixing pincers seat, be embedded in the active clamp block in the fixing pincers seat, by being contained in the spiral thumb wheel adjustable pincers piece and the width of jaw that fixing pincers seat forms on the fixing pincers seat, adapt to the screw and nut of different size.There is following problem in this monkey wrench: the one, and have only two working faces to act on nut during spanner work, easily the slip of nut generation circumferencial direction relatively; The 2nd, because it is less to be positioned at the angle of conplane handle center line and jaw center line, spanner comes off along handle orientations and nut easily.These problems affect the security and the result of use of monkey wrench.
The purpose of this utility model provides a kind ofly can prevent sliding stop and the monkey wrench that comes off with respect to securing member.
The utility model is to realize the foregoing invention purpose like this: monkey wrench comprise handle, handle one end fixing pincers seat, be embedded in the active clamp block in the fixing pincers seat, on fixing pincers seat and the active clamp block working face that acts on securing member is arranged all, on the wherein fixing pincers seat three working faces that form two 120 ° of angles are arranged, a working face is arranged on the active clamp block, this working face is gone up adjacent working face with fixing pincers seat and is formed 120 ° of angles, active clamp block forms a jaw with fixing pincers seat, and the angle that is positioned at conplane handle center line and jaw center line is 25 ° to 85 °.
In the technique scheme, when the angle of handle center line and jaw center line is 55 ° to 65 °, the better effects if of monkey wrench slip-off preventing.
In three working faces on the fixing pincers seat of the utility model, the length of the working face in the middle of being positioned at is full-length, during spanner work, if the length of side of fastener nut equals this full-length, spanner has four working faces to act on nut, the length of side of nut is less than this full-length, and then spanner all has three working faces to act on nut.That is to say that for the securing member in the spanner adaptation specification limit, the utility model all can guarantee to have at least three working faces to act on it.The working face that spanner acts on securing member is many more, and its resistance is big more, and skidproof effect is good more.Therefore, skidproof effect of the present utility model obviously is better than existing monkey wrench.In addition, owing to strengthened the angle of handle center line and jaw center line, make that spanner is not easy to come off along handle orientations and nut.
Use the utility model can avoid the securing member damage, prevent during work high above the ground that spanner from coming off and cause injury to personnel.
Further specify the technical solution of the utility model below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the utility model working state figure.
See Fig. 1, the utility model has handle 1, handle 1 one ends have fixing pincers seat 3, fixing pincers seat 3 is embedded with active clamp block 5, active clamp block 5 matches with spiral thumb wheel 2 on being contained in fixing pincers seat 3, by spiral thumb wheel 2 adjustables pincers piece 5 and fixing pincers 3 a width of jaw h that form, the securing member that adapts to different size, on fixing pincers seat 3 and the active clamp block 5 the working face A that acts on securing member is arranged all, B, C, D, on the wherein fixing pincers seat 3 two 120 ° of angle e of formation are arranged, the A of f, B, three working faces of C, working face of D is arranged on the active clamp block 5, A working face adjacent on D working face and the fixing pincers seat 3 forms 120 ° of angle g, the angle α that is positioned at conplane handle center line m and jaw center line n is 60 °, the length of side of jaw inner nut 4 equals the length of B working face on the fixing pincers seat 3, and spanner has A, B, C, four working faces of D act on nut 4.
The length of side of nut 4 is less than the length of B working face on the fixing pincers seat 3 among Fig. 2, and spanner has B, C, three working faces of D to act on nut 4.
