Abstract
The utility model relates to a diagonal wrench which is used in socket wrench tools. The power of the diagonal wrench is transferred to a hexagonal sleeve barrel through a square sleeve barrel and a pair of angle gears, a long one and a short one, which are engaged with each other by a manual ratchet wrench. So the action space position is narrowed, and a screw which has 90 DEG direction depth can be assembled and disassembled. In addition, the utility model has the advantages of simple structure and low cost.
Description
The utility model relates to the elbow wrench device in a kind of impact wrench instrument.
General box spanner need load and unload the position, deep and become the screws of 90 degree directions with the degree of depth, then must use fixing or pneumatic and electronic bent spanner.Fixing bent spanner, bent spanner handle need very big activity space, pneumatic and electronic bent spanner, and because of there are an air motor or electro-motor in inside, volume is still bigger, and cost is relatively costly.But, then just can't load and unload if the activity space position of loading and unloading screw is narrow.
The purpose of this utility model is exactly at said fixing or pneumatic and electronic bent spanner, can't load and unload that the activity space position is narrow, the problem of the screw that becomes 90 degree directions with the degree of depth and design the bent spanner of an activity, and makes the loading and unloading screw convenient.
The concrete solution of the utility model is: the movable elbow wrench device is made up of with elastic spring, square socket, Hexagonal jacket, two springs, two steel balls elbow, overcoat, long bevel gear, short bevel gear, two splicing sleeves, holes.Elbow with apply mechanically threaded connection outward, the long and short bevel gear of pair of meshing is housed in it, respectively long and short bevel gear is supported in elbow with two splicing sleeves, the splicing sleeve of long bevel gear is axially blocked by overcoat, and the splicing sleeve of short bevel gear is axially blocked with elastic spring by the hole.The other end side of the being tenon of long and short bevel gear links to each other with the Hexagonal jacket that square socket and needs loading and unloading screw adapt respectively.In the square tenon side opening of long and short bevel gear, a spring and a steel ball are housed respectively, aperture circle riveting, the steel ball activity freely, and don't can bullet from the aperture.In the use, the sleeve difficult drop-off can be transferred to sleeve again when needing.For easily manufactured, long bevel gear can be made monoblock type, also can make split typely, and head bevel gear and afterbody side's tenon are separately made, and long bevel gear is formed in weldering then.
Below in conjunction with accompanying drawing the utility model is further described
Fig. 1 is movable elbow spanner structure figure
Among Fig. 1: 1-square socket, 2-overcoat, the long bevel gear of 3-, 4-elbow, 5-splicing sleeve, the short bevel gear of 6-, 7-splicing sleeve, 8-hole elastic spring, 9-Hexagonal jacket, 10-spring, 11-steel ball.
Outstanding effect of the present utility model: the diagonal wrench device is by manual ratchet The power of spanner, by square socket, the long and short bevel gear of pair of meshing is delivered to Hexagonal jacket can be narrow with the activity space position, becomes the screw of 90 degree directions with the degree of depth Loading and unloading. And simple in structure, cheap.
Embodiment: with reference to Fig. 1, the movable elbow wrench device is made up of with elastic spring (8), Hexagonal jacket (9), spring (10), steel ball (11) square socket (1), overcoat (2), long bevel gear (3), elbow (4), splicing sleeve (5), short bevel gear (6), splicing sleeve (7), hole.Elbow (4) is used threaded connection with overcoat (2), the long bevel gear (3) of engagement, short bevel gear (6) are housed in it, splicing sleeve (5), splicing sleeve (7) will be grown bevel gear (3), short bevel gear (6) supporting respectively in elbow (4), splicing sleeve (5) is axially blocked by overcoat (2), splicing sleeve (7) is axially blocked with elastic spring (8) by the hole, square socket (1) links to each other with the square tenon of long bevel gear (3), Hexagonal jacket (9) links to each other with the square birch head of short bevel gear (6), spring (10), steel ball (11) are contained in the side opening of two square tenons, aperture circumference riveting.
Claims (2)
1, the movable elbow wrench device of using in a kind of box spanner instrument, it is characterized in that elbow (4) and overcoat (2) use threaded connection, the long bevel gear (3) of engagement is housed in it, short bevel gear (6), splicing sleeve (5), splicing sleeve (7) will be grown bevel gear (3) respectively in elbow (4), short bevel gear (6) supporting, splicing sleeve (5) is axially blocked by overcoat (2), splicing sleeve (7) is axially blocked with elastic spring (8) by the hole, square socket (1) links to each other with the square tenon of long bevel gear (3), Hexagonal jacket (9) links to each other with the square tenon of short bevel gear (6), spring (10), steel ball (11) is contained in the side opening of two square tenons, the aperture riveting.
2, movable elbow wrench device according to claim 1 is characterized in that long bevel gear (3) is whole the manufacturing, or the split manufacturing, and head bevel gear and afterbody side's tenon are separately made, and weld the growth bevel gear then.
