The screwdriver of existing market has varied, and have an independent cutter head, have the automatic telescopic 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 automatic telescopic 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 automatic telescopic multi-bit screwdriver, and easy to use, cutter head is not easily lost.
The technical solution of the utility model is: a kind of automatic telescopic 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:
Be fixed on the obstruction of sleeve lining, described obstruction is provided with multiple through hole passed for knife bar,
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,
Be set in the limit spring on knife bar, two spring ends difference apical graftings of described limit spring are in push rod and obstruction;
Described guide groove is axially provided with the locating hole with guide block snap-fit engagement near one end of opening, and the width of this locating hole is less than the width of guide groove.
Cutter head of the present utility model can be arranged to dissimilar cutter head, when needing the cutter head using a certain type, promote guide block, guide block slides axially along guide groove, because guide block is fixedly connected with push rod, and push rod is fixedly connected with knife bar, and 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, guide block is transferred in the locating hole of guide groove lower end, guide block by under the effect of limit spring along guide groove upward sliding.
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, 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, automatic telescopic 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.
