Technical field:

The utility model relates to a kind of screwdriver, and the bottle opener that particularly a kind of length can be adjusted belongs to the hardware ﹠ tools field.

Background technology:

Being used to load and unload the bottle opener of various screws, is a kind of the most frequently used hardware ﹠ tools, owing to need cooperate with the screw of various different sizes, just need the bottle opener of plurality of specifications, bottle opener at present commonly used, function singleness, a thing can only a usefulness, as 50CM or long " word " bottle opener of 80CM, the bottle opener that " cross " bottle opener that 50CM or 80CM are long and other length are fixing, its scope of application is obviously limited, and as long as the work-yard is less than its length, also just can't use, can only change other bottle opener in addition; Simultaneously, " word " screw can only be used " word " bottle opener, and " cross " screw can only be used " cross " bottle opener; In addition, " word " screw that thickness and width differ can not be used a kind of bottle opener with, and " cross " screw not of uniform size also needs to use " 0 " number to " 3 " number corresponding different bottle openers.In order to address the above problem, just need to be equipped with many bottle openers, transposing is used respectively, and is very inconvenient.In order to address this problem, a kind of multipurpose screw driver is arranged in the market, the extension bar of its structure Hexagonal jacket by the screwdriver head of handle, hexagon quarter butt with in being provided with is formed, described extension bar is fixedly mounted on the handle, screwdriver head is contained on the interior Hexagonal jacket of extension bar, the screwdriver head of changing different size can be fit to multiple screw to be used, but owing to fail to solve the flexible problem of extension bar, make the length of this multipurpose screw driver still still changeless, so still there are the needs that can not adapt to different places.

Summary of the invention:

The purpose of this utility model is in order to overcome the weak point of above-mentioned common bottle opener and multipurpose screw driver, designs a kind of simple and reasonable, adjustable length, easy to use, the telescopic multipurpose screw driver that can adapt to different places needs.

Telescopic multipurpose screw driver of the present utility model comprises the screwdriver head of handle, hexagon quarter butt and the extension bar that front end is provided with interior Hexagonal jacket, also include extension bar seat and spacer simultaneously, have the extension bar hole on described extension bar seat and the spacer, extension bar is inserted on the extension bar hole, the rear portion of extension bar seat is fixedly mounted on the front end of handle, spacer is installed on the locating hole of extension bar seat front portion, and an end of spacer stretches out the extension bar seat and can move forward and backward in locating hole.In order to prevent that extension bar from skidding off from the extension bar seat, can between the front end of extension bar seat and spacer, jump ring, packing ring and stage clip be housed.

Telescopic multipurpose screw driver of the present utility model is as long as when moving forward to the external part of spacer with the perpendicular position of extension bar, extension bar can move forward and backward in the extension bar hole and the length of regulating bottle opener, after mixing up, make the movable inclined backward extension bar that blocks of external part of spacer because of the effect of stage clip, during use, the power that extension bar moves backward is big more, the spacer angle of inclination is big more, the card power that extension bar is produced is also big more and can normally use, can easily be supporting with various screwdriver heads, have simple and reasonable, adjustable length, portably use conveniently, can adapt to the advantages such as needs of different places and all size and model screw, have wide use prospect.

Description of drawings:

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is that extension bar is inserted into structural representation on the extension bar seat in the accompanying drawing 1,
