Description
Technical field
The utility model relates to a kind of hand-held tool, particularly a kind of head-exchangeable screwdriver assembly and comprise the hand-held tool of this assembly.
Background technology
Screwdriver (i.e. screwdriver used in everyday) is widely used in the various workpiece of dismounting, and the dismounting for convenience of different size workpiece needs, and occurred many knockdown screwdrivers at present, and knockdown screwdriver can be roughly divided into two classes:
One class is screwdriver bit and batch bar or batch is removable connection between bar and handle, and screwdriver bit or batch bar are separated storages with handle, by replacing screwdriver bit or criticize bar and form different screwdrivers.This kind of screwdriver scope of application is wide, practical, but the screwdriver bit needed for changing or batch bar need specific place to deposit, so just, occupy very large space, also very inconvenient when carrying and use, and if improper easy loss collected by the screwdriver bit changed or batch bar.
Equations of The Second Kind is that screwdriver self is accompanied with extra storage device, changes screwdriver bit or criticize the screwdriver that bar forms different size by frame for movement or alternate manner.This kind of screwdriver takes up room little, easy to carry, and the screwdriver bit changed or batch bar are not easy to lose, but all stores together due to multiple screwdriver bit or batch bar, often causes screwdriver internal structure complicated, very inconvenient when causing screwdriver bit or batch bar to be changed.
Such as, the application for a patent for invention CN101537606A of China discloses a kind of combined integral screw driver.Refer to Fig. 1, it is a kind of example structure figure of this combined integral screw driver.Screwdriver is assembled by the plastic protective sleeve 502 of circular plastic toggle 505, hexagonal metallic loop bar 504, metal dop 503 and protection driver bit 501.Metal dop 503 has magnetic, handle of a knife hollow and adopt unified processing dimension, and multi-form cutter head 501 is formed a whole by the mode stacked and is stored in the loop bar 504 of screw blade.
When changing driver bit 501, dop 503 need not be pulled up or take screwdriver (loop bar 504 and toggle 505 are combined into as a whole by dop 503, do not need dismounting under normal circumstances) apart, only need the ordering adjusting driver bit 501.The fore-end of cutter head 501 is clamped with hand, overcome friction and the magnetic effect of dop 503, directly built-in cutter head 501 is taken out in screwdriver, then selected required work cutter head, this cutter head is placed in forefront, other cutter head once stacks in thereafter, and is again filled in screwdriver by dop 503.
This combined integral screw driver overcomes the drawback that Conventional combination screwdriver blade and cutter head need store respectively, and effectively the overall volume of reduction screwdriver, just can tackle dissimilar screw only by the order changing built-in cutter head.But, be also stored in loop bar 504 just because of cutter head 501 nappe type, very inconvenient when making to change cutter head.When the cutter head that such as will use is in loop bar 504 position to the rear, then could adjust to foremost by the cutter head of needs after needing to pull up the multiple cutter head in front end, complicated operation, has had a strong impact on operating efficiency.
