Description

Multi-purpose handle

Technical field

The utility model relates to a kind of handle of hand-operated tools, belongs to the hand-operated tools technical field.

Background technology

At present, the handle of hand-operated tools is connected with the connecting portion of instrument through screw or gluing mostly, and this connected mode is not easy even can't changes, and when using many instruments, just needs a plurality of handles are installed, and causes the waste of carrying inconvenient and resource easily.Through retrieval; Disclosed one Chinese patent application CN200410006855.1 has announced a kind of handsaw; Be shaped on quick-release blade clamp assemblies on its handle, rely on its locking piece and actuated piece can change multiple tool heads such as saw blade, carpet knife, file fast; But only rely on flat recess and pin to hold and fix the connecting portion of above-mentioned tool heads on this handle; So the tool heads of its installation must have with a kind of flat connecting portion with holes, and other tool heads with polygon connecting portion such as screwdriver bit etc. can not be installed, the scope of application is less.

The utility model content

The technical problem that the utility model will solve is, overcomes the limitation that the handle of above-mentioned existing hand-operated tools can only be installed the instrument with flat connecting portion with holes, proposes a kind of handle that can also Fast Installation has the hand-operated tools of polygon connecting portion.

The utility model is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of multi-purpose handle; Comprise that top axial has the axle and the handle that is connected axle of flat recess; Being with on the axle can be relative to its sleeve that moves; The inwall side face of sleeve is transitional surface, is provided with the elastic component that is enclosed within on the axle between sleeve and the axle; First pin that is with stage clip passes the sidewall that axle is positioned at the flat recess place, and an end of first pin is resisted against on the inwall of sleeve, and the other end of first pin gets in the flat recess; The top of axle also axially has the polygon groove concentric with flat recess, and second pin passes the sidewall that axle is positioned at polygon groove place, and an end of second pin is resisted against on the inwall of sleeve, and the other end of second pin gets in the polygon groove.

Preferred version one is, the inwall side face phase center roller of sleeve is eccentric, and the elastic component that is enclosed within on the axle is a torsionspring.

Preferred version two is, the inwall side face of sleeve is the conical surface, and the elastic component that is enclosed within on the axle is the compression spring.

Preferred again scheme one is that opening in the polygon groove on axle top is square groove.

Preferred again scheme two is that opening in the polygon groove on axle top is the regular hexagon groove.

The multi-purpose handle of the utility model is owing to be provided with the polygon groove, therefore compares the beneficial effect that existing handle has to be: tool heads that can general multiple shape, and change convenient, energy-conservation, portable.

The specific embodiment

Embodiment one

The multi-purpose handle of present embodiment is like Fig. 1,2,3, shown in 4; Comprise that top axial has the axle 4 and the handle that is connected axle 1 of flat recess 3; But be with the sleeve 5 that phase center roller 4 rotates on the axle 4; The inwall side face phase center roller 4 of sleeve 5 is eccentric also to have first eccentric part 9 and second eccentric part 12, is provided with between sleeve 5 and the axle to be enclosed within on the axle 4 torsionspring 8; First pin 7 that is with stage clip 6 passes the sidewall that axle 4 is positioned at flat recess 3 places; One end of first pin 7 is resisted against on first eccentric part 9 of sleeve 5 inwalls, and the other end of first pin 7 gets in the flat recess 3; The top of axle 4 also axially has with flat recess 3 concentric regular hexagon groove 10, the second pins 11 and passes the sidewall that axle 4 is positioned at regular hexagon groove 10 places; One end of second pin 11 is resisted against on second eccentric part 12 of sleeve 5 inwalls, and the other end of second pin 11 gets in the regular hexagon groove 10.

When the multi-purpose handle of the utility model uses saw blade, hold sleeve 5 and its phase center roller 4 rotated, can make sleeve 5 inwalls and first eccentric part 9 disengage with first pin 7, first pin 7 withdraws from flat recess 3 under the effect of overlapping stage clip 6 on it; Insert flat recess 3 with saw blade this moment; Unclamping sleeve 5 again makes it under the effect of torsionspring 8, be returned to the position before rotating; First eccentric part, 9 contacts, first pin 7 of sleeve 5 inwalls contacts and first pin 7 is pressed in the connecting hole of saw blades in the flat recess 3, can saw blade be securely fixed on this multi-purpose handle; Also only need rotational sleeve 5 can let first pin 7 under the effect of stage clip 8, withdraw from the connecting hole of saw blade in the time of need taking off saw blade.

When the multi-purpose handle of the utility model uses connecting portion for the orthohexagonal screwdriver bit of band groove, hold sleeve 5 and its phase center roller 4 is rotated, second eccentric part 12 and second of sleeve 5 inwalls is pinned 11 disengage; Insert regular hexagon groove 10 with screwdriver bit this moment; The sidewall of screwdriver bit can eject regular hexagon groove 10 with second pin 11; Unclamping sleeve 5 again makes it under the effect of torsionspring 8, be returned to the position before rotating; Second eccentric part 12 of sleeve 5 inwalls contacts second pin 11 again and is pressed in the groove of screwdriver bit in the regular hexagon groove 10; Can screwdriver bit be securely fixed on this multi-purpose handle, also only need rotational sleeve 5 can unload the thrust of 11 pairs of screwdriver bit grooves of second pin in the time of need taking off screwdriver bit.

Embodiment two
