Abstract

The utility model relates to a multifunctional sleeve head, which can effectively solve the problems that the conventional sleeve head cannot be randomly combined and outfitted and is inconvenient to use and low in working efficiency. According to the technical scheme, the sleeve head comprises a sleeve body and a connecting body; the sleeve body is coaxially fixed together with the connecting body through a middle body; the outside diameter of the middle body is greater than the outside diameter of the connecting body and smaller than the outside diameter of the sleeve body; and coaxial through holes are formed in the sleeve body and the middle body, and each through hole is in a step shape of which the aperture is gradually reduced from outside to inside. The sleeve head is simple in structure, novel, unique, convenient to combine, easy to operate and good in effect.

Description

A kind of multi-functional collet head

Technical field

The utility model relates to daily instrument, particularly tightens or unload a kind of multi-functional collet head of usefulness of loosening the screw a little.

Background technology

Box spanner is an instrument commonly used in living, and also is the repair outfit that must be equipped with in the repairing trades, and box spanner is to be applicable to twist status very narrow and small or cave in the very bolt or the nut of depths, owing to bolt or nut on equipment or the device differ in size; When operating personnel work, need carry a large amount of models, the different box spanner of specification, use inconvenience, inefficiency; For addressing this problem, people have developed the combined sleeve spanner, have long extension bar; Can change different collet heads as required, present collet head is because the problem that exists on the structure; Can not the combination in any suit, can only the small sleeve headgear in big collet head, but can not big collet head be enclosed within the small sleeve and use; Use inconvenient, inefficiency, thus improvement and innovate imperative.

Summary of the invention

To above-mentioned situation, for overcoming the prior art defective, the purpose of the utility model just provides a kind of multi-functional collet head, and can effectively solve collet head can not the combination in any suit, uses inconvenient and ineffective problem.

The technical scheme that the utility model solves is; Comprise sleeve body and connector; Sleeve body is fixed together through intermediate concentric and connector; The external diameter of intermediate has the through hole of concentric greater than the external diameter of the connector external diameter less than sleeve body in sleeve body and the intermediate, through hole is for from inwardly being gradually little step-like in aperture outward.

The utility model is simple in structure, and is novel unique, and combined and instant is easy to operate, effective.

The specific embodiment

Elaborate below in conjunction with the specific embodiment of accompanying drawing to the utility model.

Provide by Fig. 1-Fig. 8; The utility model comprises sleeve body and connector; Sleeve body 1 is fixed together through intermediate concentric and connector 3; The external diameter of intermediate has the through hole 4 of concentric greater than the external diameter of the connector external diameter less than sleeve body in sleeve body and the intermediate, through hole is for from inwardly being gradually little step-like in aperture outward.

Described through hole 4, intermediate and connector 3 are many prismatics, like four prismatics or six prismatics; Described intermediate is connected to form by last intermediate 2a and following intermediate 2b, and the external diameter of last intermediate is greater than the external diameter of following intermediate; Magnet opening or connecting hole 7 are arranged at described connector 3 bottoms, and magnet is housed in the magnet opening, on the outer wall of the connector of magnet opening or connecting hole top a ring annular groove 8 are arranged; The inside and outside open-work 9 perpendicular to the intermediate axle center that is communicated with is arranged on the described intermediate; Be installed with steel ball 5 on the outer wall of described intermediate, the steel ball roof pressure is in spring 6 outsides, and spring places in the wall of intermediate.

When the utility model uses, can be used as extension bar or reducing extension bar and use, a plurality of collet head combinations are when being sleeved on the turriform that is convergent together from small to large successively; Per two adjacent collet heads that are sleeved on together, wherein, the last intermediate of the collet head on top is installed in the outer stomidium of collet head through hole of bottom, adds man-hour; Can be processed into the different collet head of caliber size as required, carry out the combination of various ways; Can be combined into turriform, can also make up (shown in Fig. 4 and Fig. 8) with the big form of little cover, magnet opening or connecting hole are arranged at the bottom of connector; When being processed into connecting hole, can connect a plurality of collet heads, according to operating position; Bigger collet head can also use the intermediate or the connector of other collet head of connecting hole suit of connector, can make up each other, and two ends all can be connected with other collet head; A plurality of collet heads make up, and can replace stock, and are difficult for losing; The utility model is novel unique, and combined and instant is effective; Function is many, not only can with the box spanner use that matches, also can with impact the use that matches of screwdriver, pneumatic screw driver, ratchet spanner, open-end wrench, double offset ring spanner; Penetrate open-work with circular iron staff and can constitute the slide bar sleeve, L type elbow iron staff penetrates open-work and can constitute movable sleeve and impact the screwdriver that the impact head of screwdriver also can be combined into different length when combined.
