Screwdriver has utilization, the such as field such as machinery, electric and electronic, computer all in life or in multiple fields
Can use.But traditional screwdriver is often only furnished with the cutter head of a fixation, is not suitable for the dismounting used in complex machines and peace
In the case of dress.And screwdriver structure that some on market press tool changing head is excessively complicated, the scope being suitable for is narrower, price
Again costly.On market also have a kind of interchangeable bit screwdriver, but its desired space than larger it has not been convenient to carry.
Utility model content
The purpose of this utility model is to provide one kind to press tool changing bit screwdriver mechanism, and this mechanism has structure simply,
Low cost, reliability is high, with rapid changing knife and can facilitate the advantages of keep in repair.
For achieving the above object, this utility model adopts the following technical scheme that：
A kind of screwdriver pressing tool changing head, including tubulose blade, porose disc, some shaft-like cutter hubs, slide block, presses motion block, tight
Gu Quan and spring,
Described porose disc is provided with hexagonal central blind hole, porose disc is evenly distributed with multiple circular logical around central blind hole
Hole, porose disc is fixed on the inside of tubulose blade, and the tube wall of tubulose blade is provided with the through hole slideway of multiple tracks strip vertically,
Slide block is provided with the through hole along tubulose blade radial direction, is arranged in the through hole on slide block by motion block, is in tubulose blade by motion block
Internal one end is fixed on tight loop, and cutter hub is arranged in tight loop, and spring one end is fixed on tight loop, and the other end is fixed
On slide block, the tail shape of shaft-like cutter hub is fitted close with central blind hole.
Tubulose blade lower surface is provided with conduit radially.
Of the present utility model have the prominent advantages that：
1. this utility model moving sets and spring composition press mechanism, quickly and easily carry out tool changing, and adopt knife
Head built-in mechanism, dramatically saves on space, also provides conveniently for rapid changing knife.
2. this utility model compares other conventional screw-driver in order, has a rapid changing knife, and collection multi-knife-head is with the whole body it is adaptable to multiple
Occasion, is convenient for carrying.
3. this utility model is compared with the screwdriver of other interchangeable cutter heads, and moment is larger, the occasion work of suitable higher-strength
Use.
4. this utility model design structure is simply it is easy to maintenance, convenient and safe, is suitable for many occasions, and various crowds use.
5. this utility model moment of torsion is larger, has rapid changing knife, and how cutter head type is it is adaptable to turn round multiple big-and-middle primary screws
Nail, is suitable for using in factory or when keeping in repair at ordinary times.

Specific embodiment
Below in conjunction with the accompanying drawings specific embodiment of the present utility model is described in detail.
A kind of screwdriver pressing tool changing head, including tubulose blade 1, porose disc 4, some shaft-like cutter hubs 9, slide block 10, presses
Block 8, tight loop 11 and spring 7,
Described porose disc 4 is provided with hexagonal central blind hole 6, and porose disc is evenly distributed with multiple circles around central blind hole 6
Through hole 5, porose disc 4 is fixed on the inside of tubulose blade 1, and the tube wall of tubulose blade 1 is provided with the logical of multiple tracks strip vertically
Hole slideway 3, slide block 10 is provided with the through hole along tubulose blade radial direction, is arranged in the through hole on slide block 10 by motion block 8, by motion block
8 one end being within tubulose blade 1 are fixed on tight loop 11, and cutter hub 9 is arranged in tight loop 11, and spring one end is fixed on
On tight loop 11, the other end is fixed on slide block 10, and the tail shape of shaft-like cutter hub 9 and central blind hole 6 are fitted close.
Tubulose blade 1 lower surface is provided with conduit 12 radially.Conduit is so that while cutter hub moves down
Can smoothly move radially.
Operation principle：
When needing using screwdriver, select the cutter hub 9 needing, promote on the cutter hub chosen corresponding by motion block 5 toward knife
Slide in head direction, cutter hub together slides with by motion block, and carrying is pressed motion block slide block and slided in through hole slideway, when slide block reaches through hole
During the lower end of slideway, by applying the power along tubulose blade footpath yearning center by motion block 5 and keeping, then move toward end with push type broach
Move and press motion block so that the knife tail of shaft-like cutter hub enters in central blind hole and clamping, you can use；
When the tip shapes or use that need replacing cutter hub finish, promote and press motion block toward the movement of blade lower end, shaft-like
The afterbody of cutter hub leaves the central blind hole on porose disc, now, release along tubulose blade radial direction power, spring contraction make cutter hub to
The tube wall of tubulose blade moves, and then promotes and presses motion block toward the movement of blade upper end, the knife tail of cutter hub enters the circular through holes of porose disc
In pack up.
