Abstract
A portable small multi-purpose screw tool comprises multifunctional heads (2) which are respectively arranged in bayonets (3) on the side faces and at the bottom of a cohesive part (1), and the multifunctional heads (2) and all the bayonets (3) are close fit. The cohesive part (1) is made from permanent magnet. The portable small multi-purpose screw tool has a small size, but because of the structure of output points of hand torque force at both ends arranged far apart, large hand torsional moment can generate when the portable small multi-purpose screw tool is used, that is, a small hand torque force can realize the output of a great torque force of screwdriver head.
Description
Technical field:
The present invention relates to a kind of portable small-sized multipurpose screw tool technique.
Background technology:
At present, the screw tool that occurs on the market is of a great variety, because they carry and the convenience used is generally accepted by people institute, but, the deficiency of this class small-sized household instrument is: during use, structure by them is determined, carries out work by the mode (because the very little torsion of output that causes of diameter of handle is also very little) of holding screw driver handle, has caused the defective that the output of hand torsion is less than normal and output is inconvenient.
Summary of the invention:
The objective of the invention is:
A kind of portable small-sized screw tool structure optimization design is proposed.
In order to realize the present invention's purpose, intend adopting following technical scheme:
Have: the cutter head of various functions, it is characterized in that: the cutter head of above-mentioned various functions is separately positioned in the bayonet socket device of the side of interface components and bottom, and, the cutter head of these various functions all is in the tight fit state with being connected of each bayonet socket device,---above-mentioned interface components is made of permanent magnet.
The present invention's characteristics compared with the prior art are:
Whole volume is very little, but, because structure of the present invention (having the output point of the hand torsion of suitable width distance in the power of two ends) determines, this be just for can produce bigger hand torsional moment in use, promptly just can realize that with less hand torsion the output of bigger driver bit torsion created condition.
Description of drawings:
State when Fig. 1 has illustrated each isolation of components of the present invention.
State when Fig. 2 has illustrated each parts combination of the present invention.
Fig. 3 has illustrated the side view of interface components among the present invention.
1, interface components; 2, cutter head; 3, bayonet socket device.
The specific embodiment:
The present invention has designed respectively and can implement friction tight bayonet socket device 3 with various cutter heads 2 in the side of interface components 1 and bottom.Interface components 1 is in the bayonet socket device 3 of side and the bottom design groove shapes that is square, and the square projection of afterbody of they and cutter head 2 is in the tight fit state.
During use, a bayonet socket device 3 of interface components 1 bottom is mainly used in the vertical cutter head 2 that uses in location, the i.e. cutter head 2 of external outputting torsion; Six bayonet socket devices 3 of 1 two sides of interface components are mainly used in each relevant six horizontal cutter heads 2 that manual moment of torsion is transmitted in the location.
The imagination of being not difficult: when the present invention was in user mode, people's hand had sizable torsion by what six cutter heads 2 to located lateral applied, was easy to just can drive the cutter head 2 that is positioned at the interior vertical location of interface components 1 bottom bayonet socket device 3.---this just carries out work and has created condition for pinching (not being to hold the quite little handle of moment as using prior art) the present invention from the both sides hand with suitable width distance (moment is quite big) of the present invention very like a cork.
Be not difficult to find: any one cutter head 2 among the present invention can be inserted in any one square groove of bayonet socket device 3.That is to say: any one cutter head 2 that people need use can both be plugged in the square groove of bayonet socket device 3 bottoms and use as instrument.
Claims (2)
1, a kind of portable small-sized multipurpose screw instrument, have: the cutter head of various functions (2), it is characterized in that: the cutter head of above-mentioned various functions (2) is separately positioned in the bayonet socket device (3) of the side of interface components (1) and bottom, and the cutter head of these various functions (2) all is in the tight fit state with being connected of each bayonet socket device (3).
2, a kind of portable small-sized multipurpose screw instrument according to claim 1, it is characterized in that: described interface components (1) is made of permanent magnet.
