Abstract
The utility model discloses and a kind ofly quick adjustment can pull the spanner of mouthful size, this spanner comprises handle and is located at the spanner of handle end, connecting portion between spanner and handle arranges a cavity, is provided with worm screw and rotates thus the gear device controlling the movement of spanner movable part for promoting worm screw in cavity.Described worm screw is with in-line gears, and gear device engages with in-line gears and drives it to rotate and drives worm screw to rotate, and the final spanner movable part that controls moves forward and backward and realizes pulling the quick adjustment of mouthful size, can effectively increase work efficiency.
Description
Technical field
The utility model relates to a kind of instrument, and particularly a kind of energy quick adjustment pulls the spanner of mouthful size.
Background technology
Spanner is a kind of conventional manual repair outfit, is generally used for fastening or dismounting polygon, cylindrical parts, such as, for dismantling hex(agonal)screw.Existing spanner comprises the monkey wrench of pulling mouthful dimension adjustable and pulls the fixing back-up wrench of mouthful size.Wherein, monkey wrench is made up of handle and the spanner of being located at handle end, spanner comprises with handle integrated spanner fixture and forms relative to the spanner movable part that the activity of spanner fixture is installed, spanner movable part tail end is provided with tooth bar, spanner movable part is moved with engaging of tooth bar by worm screw, thus regulate the size of wrench mouth, to adapt to the workpiece of different size.The advantage of the spanner of this kind of structure is that structure is simple, durable, and shortcoming is that the movement of spanner movable part is relatively harder, and governing speed is slow.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and is realized easily by rational structure arrangement, regulates the spanner pulling mouthful size fast.
In order to solve the problem existing for prior art, spanner of the present utility model, comprise handle and be located at the spanner of handle end, described spanner is made up of the spanner movable part of spanner fixture and tail end band tooth bar, connecting portion between described spanner and handle is provided with a cavity, be provided with the worm screw that is meshed with spanner movable part upper rack in cavity and rotate thus the gear device controlling the movement of spanner movable part for promoting worm screw, described worm screw is with in-line gears, and gear device engages with in-line gears and drives it to rotate to drive worm screw to rotate.
Further, described gear device comprises a driving wheel and more than one drive, driving wheel run through cavity sidewalls and part expose outside cavity, drive arrange and between driving wheel and in-line gears.
Further, described drive is one.
Further, the number of teeth on described driving wheel, drive and in-line gears is successively decreased by multiple successively.
Further, the number of teeth on described driving wheel is the twice of drive, and the number of teeth of drive is the twice of in-line gears.
Compared with prior art, the beneficial effects of the utility model are:
The utility model arranges cavity at the connecting portion between spanner and handle, in cavity, arrange gear device drives spanner movable part to move fast, thus rapid adjustment pulls the size of mouth, to adapt to parts or the workpiece of different size size, because cavity is between spanner and handle, like this when holding handle, directly can use thumb control gear drive unit, operating very easy.Particularly, the number of teeth formed between the driving wheel of gear device and driven pulley and in-line gears is successively decreased according to multiple, thus real realizes quick adjustment.

In figure: handle-1 spanner-2 spanner fixture-3 spanner movable part-4 cavity-5 worm screw-6 in-line gears-7 driving wheel-8 driven pulley-9
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed explanation and explanation are done to structure of the present utility model, but be not the restriction to the utility model structure.
Please refer to the appearance assumption diagram that Fig. 1, Fig. 1 are spanners described in the utility model.
The utility model comprises handle 1 and is located at the spanner 2 of handle end, spanner 2 is made up of the spanner movable part 4 of spanner fixture 3 and tail end band tooth bar, spanner movable part 4 arranges relative to spanner fixture 3 and jointly forms clamping part, and the space between spanner movable part 4 and spanner fixture 3 is for pulling mouth.
Please refer to Fig. 2, the connecting portion between spanner 2 and handle 1 is provided with a cavity 5, is provided with worm screw 6 and rotates thus the gear device controlling spanner movable part 4 movement for promoting worm screw 6 in cavity 5.Worm screw 6 is meshed with the tooth bar on spanner movable part 4, and its afterbody installs in-line gears 7, is rotated by drive worm screw 6 when in-line gears 7 rotate, thus it is movable to promote spanner movable part 4 by worm screw 6, reaches the effect that quick adjustment pulls mouthful size.
The gear device rotated for promoting worm screw 6 achieves the goal by driving the in-line gears 7 of worm screw to rotate.This gear device comprises a driving wheel 8 and a drive 9, and drive 9 is arranged between driving wheel 8 and in-line gears 7, for the rotation of driving wheel is passed to in-line gears, thus makes driving wheel 8 can indirectly drive in-line gears 7 to rotate when rotating.Driving wheel 8 runs through cavity sidewalls and part is exposed outside cavity, the part exposed just promoting for thumb with when holding handle, make to adjust pull mouthful size simple to operate and quick, effectively increase work efficiency.
In order to reach the quick adjustment effect of getting twice the result with half the effort, the number of teeth that driving wheel 8, drive 9 and in-line gears 7 have is successively decreased by multiple successively, and namely, the number of teeth of driving wheel is the twice of drive, and the number of teeth of drive is the twice of in-line gears.
Drive number recited above can be decided according to the actual requirements, if meet the number of teeth from driving wheel to in-line gears successively by the principle that multiple successively decreases.
The above is only better embodiment of the present utility model, not any pro forma restriction is done to the utility model, therefore everyly do not depart from technical solutions of the utility model content, the any simple modification done above embodiment according to technical spirit of the present utility model or equivalent variations, all still belong in the scope of technical solutions of the utility model.
