The specific embodiment
Extremely shown in Figure 5 according to Fig. 1, the utility model is by adapter 1, the connecting screw 2 of knife bar 3 and connection adapter 1 and knife bar 3 is formed, adapter 1 comprises cylindrical sleeve 4 and taper platform connector 5, connector 5 bottoms and 4 fastening linking to each other of sleeve, connector 5 tops are provided with a projection that is rectangle 8, on projection 8, have a connecting hole 9, sleeve 4 inside are milled with several its slightly larger in diameter in the cylindrical hole of sleeve 4 tail end opening diameters, draw point 6 places in the cylindrical hole, its draw point 6 is the two-part cylinder, one end is a round end, the other end is a tack, the tack section places in the cylindrical hole and contacts with spring 7 in the cylindrical hole, the round end section extends out from sleeve 4 tail end perforates, the tack section can be free to slide in cylindrical hole, but because the slightly larger in diameter of tack section is retained in the cylindrical hole in the perforate of sleeve tail end, therefore, round end draw point 6 can freely stretch in sleeve 4, draw point 6 compression springs 7 under the situation of pressurized, in the retraction sleeve 4, the degree of retraction is decided on pressure, under the situation of pressurized not, be subjected to the effect of spring force, the round end section of draw point 6 is stretched out from sleeve 4 tail end perforates, is cut by sleeve 4 tail end perforates until draw point 6 tack sections.
Knife bar 3 is a rectangular-shaped metallic rod, one end is the handle 11 for user's gripping that is enclosed with rubber or engineering plastics, the other end is provided with concave shape opening 12,12 liang of walls of its opening are provided with the round thread perforate 13 that connecting hole 9 diameters and screw thread with projection 8 are complementary, connecting screw 2 is the straight screw that an end has spacing disk 14 and rectangle projection 15, and connecting hole 9, the knife bar 3 of its diameter and screw thread and projection 8 are complementary.
According to shown in Figure 6, during assembling, the projection on the adapter 18 is put into the concave shape opening 12 of knife bar 3 and perforate is aligned, being clamped and connected with hand, rectangle projection 15 screws in connecting screws 2 and fastening on the screw 2.Need dismounting or more during changer adapter 1, as long as outward winding connecting screw 2.If when need obtaining bigger rotating torque, as long as unclamp connecting screw 2 slightly, knife bar 3 is transferred and the upright position of 1 one-tenths 90 degree of adapter from 180 degree, rotate knife bar 3 at this moment, can produce (for example getting rusty) screw and nut that bigger power tackles tension.
When not working, round end draw points 6 all on the adapter 1 stretch out under the effect of spring force, when the general-purpose tightener is pressed on the screw and nut of the degree of tightness of wanting, the draw point 6 that touches the screw head terrace part can be under pressure and shrink in sleeve 4, and the draw point 6 that touches the screw head sunk part keeps stretching out because pressure is little or the very little distance of contraction just.The flexible state of draw point 6 changes, and forms the concaveconvex shape opposite with screw head, with the complete interlock of screw, rotate this moment the general-purpose tightener just can alternate screwdriver or instrument such as spanner come the parbuckle screw nut.
Embodiment one:
Extremely shown in Figure 8 according to Fig. 7, when screw 10 is " one " font, when adapter 1 is pressed to screw 10 heads, the draw point 6 that touches terrace part can be stressed and contraction in sleeve 4, the draw point 6 that touches " one " font groove keeps stretching out, the flexible state that is arranged in as " one " font driver bit of draw point 6 on the adapter 1, rotate the general-purpose tightener this moment just can degree of tightness " " font screw.
Embodiment two:
Extremely shown in Figure 10 according to Fig. 9, when the general-purpose tightener is applied to " ten " font screw 10, the flexible state that is arranged in as " ten " font driver bit of draw point 6 on the adapter 1, rotate the general-purpose tightener this moment just can degree of tightness " ten " font screw.The draw point that stretches out of the circle expression of institute's adularescent in the drawings, and have the draw point that the circle expression of oblique line is shunk.
Embodiment three:
Extremely shown in Figure 12 according to Figure 11, in the general-purpose tightener is applied to during hexangle type screw 10, adapter 1 is pressed to screw 10 heads, the draw point 6 that touches terrace part can be stressed and contraction in sleeve 4, the draw point 6 that touches hexagonal indentations keeps stretching out hexagon cylinder of formation, as Allen key, rotating the general-purpose tightener this moment just can the interior hexangle type screw of degree of tightness.The draw point that stretches out of the circle expression of institute's adularescent in the drawings, and have the draw point that the circle expression of oblique line is shunk.
Embodiment four:
Extremely shown in Figure 15 according to Figure 13, when the general-purpose tightener is applied to outer-hexagonal type flat head screw 10, the draw point 6 that adapter 1 touches terrace part can be stressed and contraction in sleeve 4, being wrapped in hexagon screw 10 outer draw points 6 keeps stretching out, fully contact with each limit of outer-hexagonal type screw gabarit as same hexagon sleeve or spanner, rotate the general-purpose tightener this moment just can degree of tightness outer-hexagonal type screw.The draw point that stretches out of the circle expression of institute's adularescent in the drawings, and have the draw point that the circle expression of oblique line is shunk.
In like manner analogize, it no matter is Nei Sijiao, interior star-like, interior blossom type or the like different designs, or the various screw and nut of different head profile, or even the screw and nut of special-shaped, when using the general-purpose tightener, adapter 1 can be filled the rollet of screw head fully or be wrapped up its gabarit, with the complete interlock of screw, can replace the instruments such as screwdriver, angled spoon or spanner of various different designs.
If the head of round end draw point uses magnetic material, can attract magnetic screw and nut better.
The foregoing description is only enumerated for explanation the utility model, is not to be used to limit the utility model, and the structure of any effects equivalent based on the conversion of the technical program institute all belongs to protection domain of the present utility model.
