Abstract

The utility model relates to a tool, and particularly relates to a movable spanner. The movable spanner comprises a first rod handle, a fixed spanner tooth and a movable spanner tooth, and further comprises a gear group, a first push rod, a second push rod, an adjusting push button, and a stopping push button, wherein the gear group comprises a driving gear and a driven gear, and the driven gear is engaged with the bottom surface of the movable spanner tooth; an engagement tooth is arranged on the first push rod and is engaged with the driving gear; a stopping block is fixedly connected with the top end of the second push rod, an engagement tooth is arranged on the top surface of the stopping block, and both of the first push rod and the second push rod are located in a cavity in the first rod handle; the adjusting push button is fixedly connected with the first push rod and is located on the upper surface of the first rod handle; and the stopping push button is fixedly connected with the second push rod and is located on the upper surface of the first rod handle. The movable spanner is relatively high in efficiency, relatively convenient in adjustment due to that the adjusting push button and the stopping push button are arranged at positions close to a hand, and are suitable for operation in a narrow space; and a second rod handle is arranged, and is capable of being folded without occupying a storage space when the movable spanner is not used and is unfolded to length a force arm when the movable spanner is used, so that the operation is relatively labour-saving, and a certain beneficial effect is generated.

Description

A kind of monkey wrench

Technical field

The utility model relates to a kind of instrument, especially a kind of monkey wrench.

Background technology

Monkey wrench can be used for the bolt of some kinds of specifications because of its size that can regulate opening, uses extensively.But because it is to regulate openings of sizes through the hand-screw worm screw, governing speed is slow, simultaneously after hours, needs spanner is withdrawed from bolt, again the spanner inserting bolt is carried out work, inefficiency behind the revolution certain angle; Moreover; Because of the regulator site of conventional spanner in the head end of spanner; If spanner need insert narrow space (operator is difficult to hand is put into this space) and operate then very inconvenient user and carry out real-time regulated and can cause clamping bolt fully, when twisting, can cause the spanner initiation security incident that gets loose; In addition, the traditional activity spanner does not have extension fixture, and in some cases, arm of force deficiency is difficult to tighten or backs out bolt to waste time and energy.

The utility model content

The utility model is intended to address the above problem, provide a kind of efficient higher, when return is operated, do not need to break away from bolt head and use labour-saving monkey wrench more spanner is whole, its technical scheme that adopts is following:

A kind of monkey wrench comprises the first bar handle, fixedly pulling teeth and movable pulling teeth, and said fixedly pulling teeth is fixed in the head end place of the first bar handle, and said movable pulling teeth is located in the chute of the first bar negative winding stem, and movable pulling teeth bottom surface has engaging tooth, also comprises:

Be located at the gear train in the first bar handle internal cavities, it comprises driving gear and driven gear, and said driven gear is meshed with movable pulling teeth bottom surface;

Straight-line first push rod has engaging tooth and is meshed with driving gear on it;

Straight-line second push rod, its top is connected with scotch, and the end face of said scotch is provided with engaging tooth, and said first push rod and second push rod all are arranged in the first bar handle internal cavities;

Regulate push button, itself and first push rod are affixed and be positioned at the first bar handle upper surface;

The stop push button, itself and second push rod are affixed and be positioned at the first bar handle upper surface,

Regulate push button and stop push button and be located at the position of nearly hand, movable pulling teeth is slided and then adjusting wrench opening size through promoting first push rod; Through promoting second push rod scotch is meshed with movable pulling teeth bottom surface, and then the wrench opening size is limited, the said second pushrod movement direction and the movable pulling teeth direction of motion are perpendicular.

On the technique scheme basis, said gear train is made up of driving gear, driven gear and in-line gears, and said driving gear is meshed with in-line gears, and said in-line gears are connected with driven gear is coaxial, and gear train adopts up-down structure, and integral body is compacter.

On the technique scheme basis, also comprise the second bar handle, the said second bar handle pivots with the first bar handle through the turning cylinder of being located at the first bar handle bottom and is connected, and can increase the arm of force through the second bar handle, makes this monkey wrench more laborsaving when operation.

On the technique scheme basis, the end of said second push rod is connected with a spring, and the normality lower spring promotes second push rod makes scotch be meshed with movable pulling teeth bottom surface.

The utlity model has following advantage: regulate openings of sizes through promoting to regulate push button, regulating push button is that rectilinear motion is so efficient is higher; Regulate push button and stop push button and be located at the position of nearly hand, regulate more conveniently, applicability extensively is applicable to the operation of small space; Be provided with the second bar handle, receipts are folded when not using does not account for memory space, launches the second bar handle during use, increases the arm of force, operates more laborsaving.
