Abstract

The invention provides a screw driver assistor with an angle-square shaped sleeve (1). A first conical gear (3) and a second conical gear (2) in gear transmission connection are arranged along a sleeve cavity; the first conical gear (3) extends to a connecting lug boss (6) with a hexagonal section; the external end of the second conical gear (2) is provided with a connecting lug boss (7) with a hexagonal section as well; axles of the two gears are respectively provided with a first bushing (4) and a second bushing (9). The bottom of a handle of a screw driver (11) is sheathed at one end of the connecting lug boss (6), a screw driver head (12) sheathed on the connecting lug boss (7) is driven through transferring rotating force by gear teeth, and the rotating direction of the screw driver (11) is changed from vertical to horizontal, or from horizontal to vertical, thereby realizing diverting use of the screw driver. Therefore, the performance of the screw driver can be expanded and reinforced. The assistor has the advantages of simple structure, low cost and high efficiency.

Description

Screwdriver aid

Technical field

The present invention relates to a kind of instrument, especially a kind of screwdriver aid that is used for auxiliary unskilled labor with screwdriver startup screw.

Background technology

As everyone knows, the startup of traditional screw, tighten or pine is opened, generally all be to use screwdriver, utilize its in-line or cross or hexagon blade vertical direction to insert in the in-line or cross or hexagon cutter groove of workpiece screw, clockwise or counter rotation operation screw, thus realize screw screw or loosening.But screw this screws or pine is opened and must possess a condition, and that is exactly between operator's screwdriver and workpiece screw any obstacle to be arranged, otherwise the operator can't set about.This obstruction that can overcome the known hexagonal right angle spanner that has now used realizes screwing of screw or loosening, but be to use this spanner to screw or become flexible screw, needing has a bigger operating space around the screw, and the radius of turn in this operating space is at least greater than the width of operator's palm.If screw is in the place of turning part, narrow part or the not enough screwdriver length of vertical height, just use traditional screwdriver to be difficult to deal with problems separately.

Summary of the invention

The technical problem to be solved in the present invention is that the defective at prior art exists for screwdriver provides a kind of screwdriver aid, still can successfully start screw when helping the normal screws cutter obstacle to occur between cutter hub and workpiece screw.

Technical solution of the present invention is, described screwdriver aid referring to Fig. 1～3, has angle square shape sleeve 1, and promptly sleeve 1 both sides cylindrical shell intersects vertically.Wherein at the bottom of the end tube first through hole 5 is arranged at the bottom of this sleeve 1 cylindrical shell two ends tube, second through hole 8 is arranged at the bottom of the other end tube.Be provided with first bevel gear 3 and second bevel gear 2 that tooth is in transmission connection along the tube chamber in the described sleeve 1.Wherein the wheel shaft outer end coaxial line of first bevel gear 3 is extended and one is connected first through hole 5 that boss 6 stretches out above-mentioned sleeve 1, and these connection boss 6 cross sections are hexagon; And the wheel shaft outer end coaxial line of second bevel gear 2 is provided with a connection concave station 7, and these connection concave station 7 cross sections also are hexagon.In addition, for guaranteeing the gear spin stabilization, also be respectively installed with first sleeve pipe 4 and second sleeve pipe 9 on described first bevel gear 3 and second bevel gear 2 wheel shaft separately successively so that make the wheel shaft location.

When using by the screwdriver aid of the present invention that constitutes with upper member, referring to Fig. 4, the operator can be enclosed within screwdriver aid with screwdriver 11 handles bottom and have the end that the cross section is hexagonal connection boss 6, rotary screw cutter 11 handles, first bevel gear, the 3 wheel shafts rotation of screwdriver aid, by the gear teeth revolving force is passed on second bevel gear, 2 wheel shafts, the rotation of second bevel gear, 2 wheel shafts is also passed through the hex hole that its bottom connects concave station 7, drive is enclosed within the hexagonal driver bit 12 that has that connects on the concave station 7, for example above-mentioned in-line or cross or 12 rotations of hexagonal driver bit, the vertical direction that becomes screwdriver 11 rotates to be the horizontal direction rotation, or the horizontal direction of change screwdriver 11 rotates to be the vertical direction rotation.Be that break-in is used with regard to the angle of having realized screwdriver 11 like this.

The invention has the beneficial effects as follows, by the use of screwdriver aid, enlarged and strengthened the performance of screwdriver, greatly convenient all kinds of operators implement the fastening or loosening of screw.No matter which kind of position this fastening or loosening screw is in, and generally all can realize smoothly by screwdriver aid.And this assistant structure is simple, cost is low and the efficient height.

The specific embodiment

Referring to accompanying drawing 1～3, this embodiment of screwdriver aid of the present invention caliber of drawing materials is ￠ 16mm, and pipe thickness is that the stainless steel tube section bar of 2mm is made angle square shape sleeve 1, and sleeve 1 both sides cylindrical shell is intersected vertically, wherein have first through hole 5 at the bottom of the end tube at the bottom of the tube of cylindrical shell two ends, aperture ￠ 10mm.Have second through hole 8 at the bottom of the other end tube, the aperture also is ￠ 10mm.First bevel gear 3 and second bevel gear 2 are along the setting that is in transmission connection of sleeve 1 inner core chamber tooth.Wherein the wheel shaft outer end coaxial line of first bevel gear 3 is extended and one is connected first through hole 5 that boss 6 stretches out sleeve 1.These connection boss 6 cross sections are hexagon; The wheel shaft outer end coaxial line of second bevel gear 2 is established one and is connected concave station 7, and these connection concave station 7 cross sections also are hexagon.First sleeve pipe 4 and second sleeve pipe 9 caliber of drawing materials is ￠ 11mm, and pipe thickness is that the stainless steel tube section bar of 2mm is tailored.Wherein first sleeve pipe 4 is sleeved on the wheel shaft of first bevel gear 3; Second sleeve pipe 9 is sleeved on the wheel shaft of second bevel gear 2.

On probation to be proved to be effect remarkable through manufacturing experimently for the screwdriver aid of the present invention of Gou Chenging thus, reached designing requirement.Need to prove that screwdriver is connected with screwdriver aid, screwdriver aid is connected with driver bit, is not limited to hexagonal, and the connection of other concavo-convex form all can.
