Description

But a kind of instrument of Fast Installation screw

Technical field

The utility model relates to hardware ﹠ tools, but especially a kind of instrument of Fast Installation screw.Be applicable to that the space is little, compact conformation, big, the near occasion that can't catch of installation difficulty, as aircraft, precision optical machinery etc.

Background technology

At present, must use the left hand hold-down screw when using existing screwdriver mounting screw, the right hand turns screwdriver, but place little at some installing spaces, that installation difficulty is big exists the zone that many hands can't be approaching, and very difficulty is installed.For example, aboard, when using the normal screws cutter to install, because screw can't be located, mounting screw is difficulty very, and installation effectiveness is low; In addition, on aircraft wing or fuselage during mounting screw, combining easily between screwdriver and the screw skidded, the aluminium matter covering of be easy to after the edge of a knife of screwdriver skids off to damage hand and wrap up.

Summary of the invention

The technical problems to be solved in the utility model is: provide a kind of fast, accurately, safety, be difficult for slippage, can not skid, screw is with easy access, operation is time saving and energy saving, but the instrument of the high Fast Installation screw of installation effectiveness.

The technical scheme that the utility model adopted is: but the instrument of Fast Installation screw, spiral shell head with handle, elongated screw rod and screw tip and screw coupling, columniform fixator is equipped with in the bottom that it is characterized in that screw rod, fixer has cavity, upper end open, Lower Half has the breach of semi-annular shape along axis, but the bottom has the draw-in groove of hold-down screw; There is the friction top of kink on screw rod at fixator upper end open place, spacer pin is equipped with in a distance, friction top top, in the fixator chamber below the friction top spring that is enclosed within on the screw rod is arranged, below the spring for being enclosed within the round catch on the screw rod, justify catch below be the shop bolt that is contained on the screw rod.

The draw-in groove inner face of described retainer bottom is provided with the inclined-plane, and draw-in groove has one to extend band along opening part.

Described handle is the straight grip with the screw coaxial line; Also can be to become 90 ° Level handle with screw rod, between handle and the screw rod by the adapter transition.

The spiral shell head of described screw rod lower end is a word spiral shell head; It also can be cross spiral shell head.

The beneficial effects of the utility model are: use this instrument only just can quickly and accurately screw be aimed at screw and directly be screwed into screw with a hand, screw is difficult for slippage, can skid during operation; Screw is with easy access, operation is time saving and energy saving, can improve installation effectiveness greatly; Can avoid damage that the surface is installed effectively, also safer to operating personnel.

The specific embodiment

Embodiment one,

Shown in Fig. 1-5, present embodiment comprises handle 1, spacer pin 2, friction top 3, spring 4, circle catch 5, shop bolt 6, fixator 7, screw rod 8.

Handle 1 is a straight grip, with elongated screw rod 8 coaxial one, diameter is thicker and be shaped on vertical stripes than screw rod, and the lower end of screw rod is the spiral shell head 8-1 with the screw coupling, its shape can be a word, cross, triangle, quincunx or other shape, to adapt to the shape need of screw.The fixator 7 that is used for fixing screw is housed in the bottom of screw rod, fixator is the cylinder that there is circular cavity an inside, upper end open, the lower end has circular arc, cylindrical Lower Half is left the breach 7-1 of a semi-round ring shape along axis, for screw into and out of usefulness, the bottom of fixator has diameter and the corresponding draw-in groove 7-2 of screw diameter, it is open that this draw-in groove is semicircle, be that half is semicircle and has 45 ° inclined-plane 7-2-1, the another side opening part connects to extend is with 7-2-2, so that the screw location is more stable.During assembling, fix a location pin 6 earlier from spiral shell head 8-1 a distance in the bottom of screw rod 8, a top diameter and the round accordingly catch 5 of fixator 7 inner diameters of on screw rod, overlapping of pin 6, promptly round catch can move up and down in fixator, be with spring 4 on the screw rod of circle catch top, friction top 3 is housed above the spring, friction top and fixator 7 inwall tight fits, but circular hole in the middle of the friction top and screw rod are movingly, screw rod can move up and down within it, fixes a spacer pin 2 on the screw rod of a distance, friction top top.The utility model spiral shell head under free state stretches into half of draw-in groove 7-2 under the effect of spring.

During use, screw is put into draw-in groove 7-2 from the breach 7-1 of fixator 7, during placement spring is gone up the top slightly, after screw was put into, spring discharged, and the spiral shell head promptly withstands following screw, at this moment just screw can be moved to the screw that needs assembling, turn handle 1 and screw can be screwed into screw.Install when removing,, just can make fixator leave screw as long as handle is drawn on slightly and laterally move toward the rear of breach.

Embodiment two,

Shown in Fig. 3-7, the basic structure of present embodiment is identical with embodiment one, and difference is the handle of instrument, and handle 1 horizontally rotates in this embodiment, just with 8 one-tenth 90 ° of screw rods, passes through an adapter 9 transition between handle and the screw rod.Method of operating is identical with last example, repeats no more.

It is described that the shape of the shape of handle, spiral shell head not only is only limited to the foregoing description, can change to some extent in protection domain of the present utility model according to different installation environments.

In structure of the present utility model, because a thickness is arranged at the bottom of fixator 7, after the screw-driving fixator withdraws from, screw also is not screwed into installing hole fully in fact, especially the countersunk head of sunk screw does not also sink in the counterbore, but locate fully owing to screw this moment, so just can fourth as long as reprocess with the normal screws cutter.
