Description

But a kind of instrument of Fast Installation screw rod

Technical field

The utility model relates to hardware ﹠ tools, but especially a kind of instrument of Fast Installation screw rod.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, when using existing screw sleeve that screw rod is installed, must use the left hand standing screw, the right hand turns sleeve or spanner, but the place little at some installing spaces, that installation difficulty is big, exist the zone that many hands can't be approaching on the accurate mechanical equipment as aircraft, compact conformation, when using ordinary cartridge or spanner to install, because screw rod can't be located, very difficulty of screw rod is installed, and installation effectiveness is low.

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 rod is with easy access, operation is time saving and energy saving, but the instrument of the high Fast Installation screw rod of installation effectiveness.

The technical scheme that the utility model adopted is: but the instrument of Fast Installation screw rod, sleeve with handle, elongated socket bar and socket bar top and screw rod coupling, columniform fixator is equipped with in the bottom that it is characterized in that socket bar, 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 standing screw; There is the friction top of kink on socket bar 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 socket bar is arranged, below the spring for being enclosed within round catch on the socket bar, justify catch below be the shop bolt that is contained on the socket bar.

The draw-in groove of described retainer bottom has one to extend band along opening part.

Described handle is the straight grip with the socket bar coaxial line.

Described handle is for becoming 90 ° Level handle with socket bar, between handle and the socket bar by the adapter transition.

The sleeve of described socket bar lower end can be interior hexagon; Also can be interior quincunx.

The beneficial effects of the utility model are: use this instrument only to need just can quickly and accurately screw rod be aimed at screw and directly be screwed into screw with a hand, screw rod is difficult for slippage, can skid during operation; Screw rod is with easy access, operation is time saving and energy saving, can improve installation effectiveness greatly.

The specific embodiment

Embodiment one,

Shown in Fig. 1-5, present embodiment comprises that handle 1, spacer pin 2, friction top 3, spring 4, circle catch 5, shop bolt 6, fixator 7, head have the socket bar 8 of sleeve 8-1.

Handle 1 is a straight grip, with elongated socket bar 8 coaxial one, diameter is thicker and be shaped on vertical stripes than socket bar, the sleeve 8-1 of the lower end of socket bar for being complementary with the turret head screw rod, its shape can be interior hexagon, interior quincunx or other shape, to adapt to not threaded shape need.The fixator 7 that is used for fixing screw rod is housed in the bottom of socket bar, fixator is the cylinder that there is circular cavity an inside, upper end open, the lower end has circular arc, and cylindrical Lower Half is left the breach 7-1 of a semi-round ring shape along axis, for screw rod into and out of usefulness, the bottom of fixator has diameter and the corresponding draw-in groove 7-2 of turret head screw diameter, it is open that this draw-in groove is semicircle, connects along semicircular opening part to extend band 7-2-1, so that the screw rod location is more stable.During assembling, fix a location pin 6 earlier from a distance, sleeve 8-1 top in the bottom of socket bar 8, the top round catch 5 that cover one diameter equates with fixator 7 inner diameters on socket bar of pin 6, promptly round catch can move up and down in fixator, be with spring 4 on the socket bar 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 socket bar are movingly, be that socket bar can move up and down within it, fix a spacer pin 2 on the socket bar of a distance, friction top top.The utility model its top under the effect of free state lower sleeve 8-1 at spring props up the bottom of fixator.

During use, the turret head screw rod that need install is put into draw-in groove 7-2 from the breach 7-1 of fixator 7, during placement sleeve is gone up the top slightly, after screw rod is put into, spring discharges, sleeve promptly withstands following screw head, at this moment just screw rod can be moved to the screw that needs assembling, turns handle 1 and screw rod can be screwed into screw.Install when removing,, just can make fixator leave screw rod 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 socket bars, passes through an adapter 9 transition between handle and the socket bar.Method of operating is identical with last example, repeats no more.

The shape of handle, that the shape of sleeve inner not only is only limited to the foregoing description is described, 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, when screw rod is tightened, after fixator withdraws from, screw rod also is not screwed into installing hole fully in fact, but locatees fully owing to screw rod this moment, so as long as reprocess just passable with common sleeve or spanner.
