Abstract

The utility model discloses a movable wrench, which is composed of a handle (1), a movable vice jaw A (3), a movable vice jaw B (4), a pin (2), a V-shaped slot A (5), a V-shaped slot B (9), a return spring (6), adjusting clamping teeth (7), a gear rack (8), etc. The utility model has the advantages of convenient utilization, automatic regulation for the width of the vice jaw, gapless fit between the vice jaw and a workpiece, high regulation sensitivity and high utilization precision and is a hardware tool with wide purposes and high service efficiency.

Description

A kind of monkey wrench

The utility model relates to a kind of monkey wrench, belongs to the hardware ﹠ tools technical field.

Monkey wrench is a kind of hardware ﹠ tools commonly used.Its width of jaw of common monkey wrench needs to be adjusted by set screw, and therefore have following defective: one is to use inconvenience.In use, its width of jaw is regulated trouble.The 2nd, be gapped the cooperation between jaw and workpiece, bigger to the workpiece damage.The 3rd, along with the prolongation of service time, it is big that the gap between set screw and tooth bar becomes, and makes width of jaw regulate sensitivity and reduce, and influences the service precision of monkey wrench, slippage easily.

The purpose of this utility model is to provide between the adjusting automatically of a kind of width of jaw, jaw and workpiece no gap to cooperate and regulates sensitivity and the high novel movable spanner of service precision.

The utility model takes following technical scheme to solve: a kind of monkey wrench, it is made up of handle, moving jaw etc., end at handle (1) is provided with adjusting clamping tooth (7), moving jaw A (3) and moving jaw B (4) are movably connected on by pin (2) and regulate the circle centre position that clamps tooth (7) basic circle, regulate tooth bar (8) engagement that clamps on tooth (7) and the moving jaw B (4).

For monkey wrench is resetted freely, around pin (2) back-moving spring (6) is set, the one end is fixed on the handle (1), the other end is fixed on the moving jaw A (3).

Convenient for when installing and removing, using than primary nut or screw, at the nearly vice jaw part position of moving jaw A (3) and moving jaw B (4) V-shaped groove B (9) is set.

For increasing the clamping degree between jaw and workpiece, V-shaped groove A (5) is set at all the other positions of jaw of moving jaw A (3) and moving jaw B (4).

The utlity model has easy to use, width of jaw adjusting automatically, jaw does not have the gap with workpiece and cooperates, regulates sensitivity and the high advantage of service precision, is a kind of of many uses, hardware ﹠ tools that service efficiency is high.

Accompanying drawing and drawing explanation.
