Preferably, the wrench further comprises a fixing strip, and the fixing strip is fixed below the rotating rod in parallel;
the fixed slot has been seted up at the middle part edge of adjustment sheet, rotates when the adjustment sheet around the rotary rod and when the middle part of adjustment sheet rotated to the rotary rod below, thereby the fixed slot can imbed the fixed strip and set up the adjustment sheet and be fixed in the fixed strip.
Optionally, a regulating sheet placing opening is formed in the area of the transverse wrench head below the rotating rod.
Optionally, two ends of the rotating rod are respectively connected with a bracket, and the bracket is vertically fixed on the transverse wrench head; a space for placing the adjusting sheet is left between the rotating rod and the transverse wrench head.
The invention has the advantages that the actual size of the opening can be adjusted by rotating and adjusting the number of the adjusting sheets placed in the opening, thereby adapting to different working environments; compared with the prior art, the structure is simpler, and the manufacturing complexity and the manufacturing cost are lower.
Drawings
FIG. 1 is a schematic view of a wrench of the present invention;
fig. 2 is a schematic view of the wrench adjustment tab of the present invention.
In the figure, the wrench comprises a vertical wrench head 1, a horizontal wrench head 2, a rotary rod 3, a rotary rod 4, an adjusting sheet 5, a contact point 6, a fixing strip 7, a handle 8, a rotary hole 9 and a fixing groove.
Detailed Description
The following describes embodiments of the present invention with reference to the drawings.
As shown in fig. 1 and 2, the adjustable wrench of the present invention comprises a solid wrench (wrench with fixed opening size), the solid wrench comprises a U-shaped opening, the opening is enclosed by a horizontal wrench head 2 located below the opening and vertical wrench heads 1 located on the left and right sides of the opening and parallel to each other; the solid wrench also comprises a handle 7 vertically connected below the transverse wrench head 2, and the handle 7 is parallel to the vertical wrench head 1;
the spanner still includes:
the rotating rod 3 is fixed on the transverse wrench head 2 in parallel;
the lower part of the adjusting sheet 4 is provided with a rotating hole 8, and the rotating rod 3 penetrates through the rotating hole 8 so as to rotationally fix the adjusting sheets 4 on the rotating rod 3; the adjusting sheet 4 is parallel to the vertical wrench head 1; one point on the upper part of the adjusting sheet 4 forms a contact point 5 through extrusion on one side, the contact point 5 is a circular groove on the extrusion side, and a fixed round bulge is arranged on the other side; one of the vertical wrench heads 1 is provided with a wrench head groove which is completely the same as the circular groove of the contact point 5 on the surface facing the opening; the fixed round bulge of each contact point 5 faces the wrench head groove; the adjusting sheets 4 are arranged along the bottom edge of the opening from the position of the wrench head groove, and the adjusting sheets 4 are abutted in parallel and can be in contact fixing through a contact point 5 in the following way: in any two adjacent contact points 5, the fixed round protrusion of one contact point 5 is embedded into the round groove of the other contact point 5; the fixing boss of the contact point 5 on one of the flaps 4 closest to the recess of the wrench can be inserted into the recess of the wrench to fix the flap 4 to the vertical wrench 1.
In order to place the unused adjusting sheet 4, the wrench also comprises a fixing strip 6, and the fixing strip 6 is fixed below the rotating rod 3 in parallel;
