Abstract

A movable wrench comprises a handle, a wrench head, and a wrench rod between the handle and the wrench head, wherein the wrench rod is cylindrical, and a square thread is formed in the wrench rod; a movable clamp is in sliding fit with the square thread; an adjusting nut is arranged in a notch in the middle of the movable clamp, and is screwed in the square thread; a locking nut is arranged on the outer side of the movable clamp, and is also screwed in the square thread. According to the utility model, the movable clamp is in sliding fit with the square thread; the adjusting nut is used for adjusting the distance between the wrench head and the movable clamp; the adjustable range is wide; the movable wrench is suitable for mounting and dismantling of a large nut. During use, the locking nut is loosen through screwing, then the distance between the wrench head and the movable clamp is adjusted through the adjusting nut so that the nut to be mounted or dismantled can be clamped properly, finally the locking nut is screwed tight so that the movable clamp is fixed onto the wrench rod; in this manner, during mounting and dismantling of the large nut, the action is stable and reliable, the work efficiency is high, and the movable wrench has the characteristics of simple structure, reasonable design, and the like.

Description

A kind of monkey wrench
Technical field
The utility model belongs to the spanner technical field, specifically relates to a kind of monkey wrench.
Background technology
Often use monkey wrench at the dismounting nut, monkey wrench can be pulled by active card and regulate the distance of spanner between pulling with active card, to be applicable to different big or small nuts.Conventional monkey wrench is subjected to structural limitations, and adjustable distance is limited in scope, and can not be used for large-scale dismounting nut.
Summary of the invention
The utility model is mainly to solve the existing technical problem of above-mentioned prior art, and a kind of monkey wrench is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of monkey wrench, comprise handle and spanner and tommy bar between the two, described tommy bar is cylindric, and be provided with flat thread, being equipped with active card on flat thread pulls, be provided with adjusting nut in breach in the middle part of active card is pulled, adjusting nut screws on flat thread.
As preferably, the outside that described active card is pulled also is provided with locking nut, and locking nut also screws on flat thread.
The utility model is equipped with active card and pulls on the flat thread of tommy bar, regulate spanner and the active card distance between pulling by adjusting nut, and the adjustable distance scope is large, applicable to large-scale dismounting nut.During use, unscrewed before this locking nut, regulating spanner and the active card distance between pulling by adjusting nut just blocks after the dismounting nut, again locking nut is screwed, make active card pull and be fixed on tommy bar, having stable behavior is reliable when the dismounting large-scale nut like this, and high efficiency has the characteristics such as simple in structure, reasonable in design.
