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.
