Abstract
The invention discloses a stress application handle for an internal angle spanner, characterized by comprising a spanner main body, a plurality of central accessories and fastening bolts for locking the central accessories; the spanner main body is composed of a central part and handles fixedly connected with two sides of the central part; a vertical placing through hole for placing the central accessories is formed at the centre of the central part; horizontal bolt holes provided with threads for allowing the fastening bolts to penetrate through are arranged in the side wall of the placing through hole; and the central accessories are provided with internal angle holes for holding the internal angle spanner. The invention has the advantages that the plurality of replaceable central accessories are adapted to apply stress on different internal angle spanners, the handles at the two sides are used for greatly improving the force of arm in the rotation, a user can easily fasten and detach the spanner by using a smaller force, the stress application handle is simple and practical in structure and low in cost.
Description
Technical field
The present invention relates to a kind of auxiliary instrument, be specifically related to a kind of afterburning handle that is applicable to the interior angle spanner.
Background technology
The interior angle screw is usually used in mechanically, mainly contains to be convenient to fasteningly, and dismounting is not easy advantages such as sliding angle, such as hexagon socket head cap screw.Need fasteningly during, often adopt interior angle spanner as shown in Figure 1, be used for fastening interior angle spanner and just be called inner hexagon spanner with the dismounting hexagon socket head cap screw with dismounting interior angle screw.The interior angle spanner often becomes that " " font, its purpose are L, and the bigger arm of force is provided when turn.During for the less interior angle screw of some size, the arm of force that corresponding interior angle spanner provides is also less, is not easy fastening and dismounting but sometimes.
Summary of the invention
Be to solve the deficiency of prior art, the object of the present invention is to provide a kind of interior angle screw that can be suitable for a plurality of sizes the interior angle spanner add torque wrench.Especially to the torque wrench that adds of the inner hexagon spanner of the metric size of standard.
The present invention adopts following technical scheme:
Be applicable to the afterburning handle of interior angle spanner; It is characterized in that; Comprise: wrench body, a plurality of centers accessory, be used to lock above-mentioned center accessory fastening bolt; Above-mentioned wrench body is divided into: central part constitutes the handle that is fixedly connected with it with its both sides, and the center of above-mentioned central part is formed with the vertical placement through hole that is used to place above-mentioned center accessory, offers on the sidewall of above-mentioned placement through hole to supply above-mentioned fastening bolt to pass and be provided with the bolt hole of screw thread, level; Automobile parts center, above-mentioned center is provided with the interior angle hole that is used to hold the interior angle spanner.
The aforesaid afterburning handle that is applicable to the interior angle spanner; It is characterized in that the profile of above-mentioned center accessory is that the cuboid of two different sizes combines, the geometric center of two cuboids is on same straight line; Form step between them, above-mentioned placement through hole is a shoulder hole.
The aforesaid afterburning handle that is applicable to the interior angle spanner is characterized in that the interior angle hole of above-mentioned center accessory is an inner hexagonal hole.
The aforesaid afterburning handle that is applicable to the interior angle spanner is characterized in that above-mentioned handle is provided with the annular knurl striped.
Usefulness of the present invention is: adopted a plurality of center accessories that can change; Can carry out reinforcing for different interior angle spanners; The arm of force when handle of both sides has improved turn greatly; Make the user can spend littler power to carry out fastening easily and dismounting, the present invention's practicality simple for structure, cost is low relatively.
Description of drawings
Fig. 1 is the structural representation of interior angle spanner;
Fig. 2 is the plan structure sketch map of a preferred embodiment of the afterburning handle that is applicable to the interior angle spanner of the present invention;
Fig. 3 is an embodiment side sectional structure sketch map shown in Figure 2.
The implication of Reference numeral among the figure:
2, center accessory, 3, fastening bolt, 4, central part, 5, handle, 6, place through hole, 7, bolt hole, 8, the interior angle hole.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is done concrete introduction.
See figures.1.and.2, the afterburning handle of interior angle spanner that is applicable to of the present invention mainly comprises: wrench body, a plurality of centers accessory 2, fastening bolt 3.
Wherein, wrench body comprises: central part 4 constitutes the handle 5 that is fixedly connected with it with its both sides, and the effect of handle 5 is in use, supplies user's both hands to go operation.The effect of central part 4 is to be used for fixing the center accessory 2 that can change.
For can fixed center accessory 2; The center of central part 4 is formed with the placement through hole 6 that is used to place above-mentioned center accessory 2; The shape of placing through hole 6 should be consistent with the shape of center accessory 2; So that can closely contact with the hole wall that prevents through hole 6 by center accessory 2, guarantee situation about not getting loose at turn-knob handle 5.
The sidewall of placing through hole 6 has the bolt hole 7 of screwed level, and is when center accessory 2 is placed in the placement through hole 6, fixing for better; Make fastening bolt 3 precession bolts hole 7; And then passing bolt hole 7, fastening bolt 3 contacts with center accessory 2, and then locking center accessory 2.The many more center accessories 2 that can guarantee more of fastening bolt 3 precessions are locked in the placement through hole 6.
As a kind of preferred version; In order to prevent that center accessory 2 from dropping, accessory 2 profiles in center are that the cuboid of two different sizes combines, and the geometric center of two cuboids is on same straight line; Form step between them, placing through hole 6 is up big and down small shoulder hole.So, the ladder of center accessory 2 and the ladder overlap joint of placing through hole 6 guarantee not landing downwards of center accessory 2.
As a kind of preferred version, the interior angle hole 8 of center accessory 2 is an inner hexagonal hole, and it can hold the inner hexagon spanner of the standard of metric system.
As a kind of preferred version, be more suitable for operation in order to make handle 5, at handle 5 annular knurl stripeds, increase its frictional force.
The foregoing description does not limit the present invention in any form, and all employings are equal to the technical scheme that mode obtained of replacement or equivalent transformation, all drop in protection scope of the present invention.
