Multifunctional self-locking wrench

Abstract

The invention discloses a multifunctional self-locking wrench. The multifunctional self-locking wrench comprises handles, wherein the handles comprise a first handle and a second handle, a first clamping part and a second clamping part are arranged at the top of the first handle and the top of the second handle respectively, a sliding block I is arranged at the first clamping part and is matched with a sliding groove I, a through hole is formed in the position, close to the bottom, of the first clamping part, a stop bolt is mounted in the through hole, and obliquely downward sawteeth I are arranged at the upper half of the sliding block I; the second clamping part comprises a movable claw and a sliding groove II which are glidingly connected with each other; when a nut or a tubular object is tightened, the obliquely downward sawteeth are arranged at the upper half of the sliding block I of the first clamping part, the stop bolt is matched with a stop block, the sliding block I is limited, the sawteeth are matched with the movable claw of the second clamping part, the nut or the tubular object is locked, and skidding is prevented, so that the nut or the tubular object can be tightened quickly and easily by the aid of the multifunctional self-locking wrench. Besides, the multifunctional self-locking wrench can also be used as a monkey wrench, an object is placed between the lower half of the sliding block I and the movable claw to be clamped, and the object is prevented from being damaged.

Description

technical field [0001] The invention relates to an auxiliary tool, in particular to a multifunctional self-locking wrench. Background technique [0002] Traditional wrenches can only twist hexagonal nuts and square nuts, but cannot twist tubular objects and nuts of other shapes. When the nut is rusted, due to the insufficient force of the wrench, the nut cannot be unscrewed, and there is a possibility of slippage, and the shape of the nut is damaged. Moreover, after the traditional wrench has finished screwing the nut once, it is difficult to reset the wrench. It is often necessary to take the wrench out of the nut, then return to the original position to lock the nut, and repeat the operation of screwing the nut. In addition, when screwing objects with traditional wrenches, it is necessary to repeatedly adjust the worm wheel to find the opening distance of the wrench, and the wrench is also very easy to loosen during repeated clamping, which brings great difficulty to the ...

Problems solved by technology

[0002] Traditional wrenches can only screw hex nuts and square nuts, but cannot screw tubular objects and nuts of other shapes

When the nut is rusted, due to the insufficient force of the wrench, the nut cannot be unscrewed and may slip off, and the shape of the nut will also be damaged

Moreover, after the traditional wrench has finished screwing the nut once, the reset operation is difficult. It is often necessary to take out the wrench from the nut, and then return to the nut to lock the nut, and repeat the operation of screwing the nut

In addition, when screwing objects with traditional wrenches, it is necessary to repeatedly adjust the worm gear to find the opening distance of the wrench, and the wrench is also very easy to loosen during repeated clamping, which brings great difficulty to the operation.

The pipe wrench is mainly used for twisting tubular objects. Because the pipe wrench is heavy and has teeth on both sides, it will cause great damage to the wrung object, so the scope of use of the pipe wrench is limited.
