Description

A kind of multi-bit screwdriver

Technical field

The utility model belongs to handware production technical field, is specifically related to a kind of multi-bit screwdriver.

Background technology

Screwdriver is a kind of instrument fixed by screw in a rotative pattern or transfer to, usually a thin sphenocephaly (cutter head) is had, in the line of rabbet joint that can insert screw cap or recess, mainly contain a word (negative sign) and cross (positive sign) two kinds, common also has hex(agonal)screw cutter, comprises interior hexagonal and outer-hexagonal two kinds.During use, the top line of rabbet joint or recess, the then rotary handle of screw is aimed in termination screwdriver being had specialization shape, under normal circumstances, according to specification standards, rotating to be tightly embedding clockwise, counterclockwise rotating then for easing out.

The screwdriver of existing market has varied, and have an independent cutter head, have the multi-bit screwdriver of interchangeable bit, the screwdriver of an independent cutter head does not possess the screwdriver of other shape, therefore uses very inconvenient yet.Although the multi-bit screwdriver of existing interchangeable bit is more convenient in use, change in use in the process of cutter head, do not note depositing the loss that can will cause cutter head, will operating efficiency be reduced.

Utility model content

The utility model provides a kind of multi-bit screwdriver, easy to use, and cutter head is not easily lost.

The technical solution of the utility model is: a kind of multi-bit screwdriver, comprise sleeve and multiple cutter hub, some are offered along quill to arrange and for the accommodating slideway of cutter hub, this slideway at least one end runs through sleeve axial end portion and forms the opening leant out for cutter hub in described sleeve; The knife bar that described cutter hub comprises cutter head and engages with cutter head, sleeve is also provided with and somely leans out the pushing mechanism of opening for promoting cutter head with slipway location one_to_one corresponding, described pushing mechanism comprises:

Along quill to setting, be positioned at sleeve perpendicular wall surfaces and extend to the guide groove of slideway,

Push rod co-axially fixed with knife bar,

To be slidably mounted in guide groove and the guide block be fixedly connected with push rod;

The axial two ends of described guide groove are respectively equipped with the locating hole with guide block snap-fit engagement, and the width of this locating hole is less than the width of guide groove.Jacket casing jacket casing jacket casing jacket casing jacket casing jacket casing cylinder guide block sleeve guide block cutter head of the present utility model can be arranged to dissimilar cutter head, when needing the cutter head using a certain type, guide block is transferred to by guide block from the locating hole of guide groove upper end, and promote guide block downwards, guide block will slide along guide groove, because guide block is fixedly connected with push rod, and push rod is fixedly connected with knife bar, therefore while guide block slip, knife bar also glides thereupon, guide block, after cutter head leans out opening, is connected in the locating hole place of guide groove lower end by sleeve.

After finishing using, transferred to by guide block in the locating hole of guide groove lower end, along guide groove upward sliding, guide block after in cutter head retraction slideway, is fixed on the locating hole place of guide groove upper end by sleeve.

After guide block and locating hole snap-fit engagement, in order to prevent guide block in the utility model use procedure, deviating from, as preferably, described sleeve perisporium offers the pin-and-hole crossing guide groove owing to exerting a force excessive in locating hole, sliding in this pin-and-hole is provided with backing pin; Described pin-and-hole position is arranged near guide groove end.After guide block and locating hole snap-fit engagement, promote backing pin, backing pin will carry out further spacing to guide block, prevent guide block from deviating from locating hole.

As preferably, the inner hollow of described knife bar, one end of described push rod is embedded in the hollow part of knife bar.

As preferably, described cutter head is yi word pattern cutter head or cross cutter head.

As preferably, described sleeve outer wall is provided with leather skid resistant course.

As preferably, described sleeve outer wall is provided with grabs the depression of taking for hand.

As preferably, described sleeve outer wall is provided with the decorative pattern in irregular arrangement.

Compared with prior art, the beneficial effects of the utility model are embodied in:

When needing to use dissimilar cutter head, multi-bit screwdriver of the present utility model only need touch corresponding guide block, very easy to use, and all cutter heads are all positioned at same sleeve, and carry also more convenient, cutter head is not easily lost.
