Specific embodiment

As shown in Figure 1, Figure 2, Figure 3 shows, the utility model provides a kind of self-control and extends allen wrench, including extension rod 1, molten Connecting terminal 2 and inserting terminal 3, in which:

The cross-sectional shape of the extension rod 1 is unlimited (can be hexagon, be also possible to round or square), length side To shape it is also unlimited (can be straight, be also possible to curved)；In the present embodiment, for the ease of scene materials, directly select Its both ends is referred to as convenience and pulls arm 11 and cursor 12 by common L-shaped interior hexagonal tommy bar；In order to Can soket head cap screw be tightened or be unscrewed, the extension rod 1 needs reciprocally swinging in a plane, herein by the plane Referred to as swinging plane；

The welding terminal 2 forms (ginseng by an interior hexagonal crossover sub 21 and interior 22 welding of quadrangle crossover sub See Fig. 4), the interior hexagonal crossover sub 21 has one end of Hexagon hole and 12 grafting of cursor of the extension rod 1, another The lateral surface welding with the interior quadrangle crossover sub 22 is held to be integrated, the interior quadrangle crossover sub 22 has interior four corner apertures One end is stretched out along the direction perpendicular to the swinging plane；

The inserting terminal 3 is made of hexagonal crossover sub in another, one end with Hexagon hole along perpendicular to The direction of the swinging plane is stretched out, and the side of the other end offers opposite perforation 31, the cross-sectional shape of the perforation 31 It matches with the cross-sectional shape of the extension rod 1, the arm 11 of pulling of the extension rod 1 is plugged in the perforation 31 and consolidates It is fixed；In order to reverse target hexagonal socket nut, also it is inserted in the Hexagon hole of the hexagonal adapter coupling in another One interior hexagonal throw rod 32.

When needing torsion to be difficult to the soket head cap screw at the position for being placed in spanner inside corner, machine, will combine 3 one end of inserting terminal that good self-control extends allen wrench is protruded into inside machine, and passes through interior hexagonal throw rod 32 and interior six Angle screw matches, and 2 one end of welding terminal for making extension allen wrench by oneself is then located at machine exterior, and torque spanner is easy to Four corner apertures match in capable of having with the interior quadrangle crossover sub 22 of the welding terminal 2, later, machine exterior can Torque spanner is easily swung, the soket head cap screw is tightened or unscrewed.

It again as shown in Figure 5, Figure 6, is all to connect inserting terminal 3 at the both ends of extension rod 1, slightly different, wherein one A inserting terminal 3 is consistent with the structure in Fig. 1, stretches out a Hexagon hole, for connecting interior hexagonal throw rod 32, and another The structure of inserting terminal 3 is different, which is made of interior quadrangle crossover sub, with interior quadrangle (for connecting with torque spanner) is stretched out along the direction perpendicular to the swinging plane in the one end in hole, and the side of the other end opens up There is opposite perforation 31, the cross-sectional shape of the perforation 31 matches with the cross-sectional shape of the extension rod 1, the extension The arm 11 of pulling of bar 1 is plugged in the perforation 31 and fixes.

In addition to above-described embodiment, the utility model can also all connect welding terminal 2 at the both ends of extension rod 1, as Fig. 7, Shown in Fig. 8, one of welding terminal stretches out a Hexagon hole, for connecting interior hexagonal throw rod 32, another welding end Son stretches out four corner apertures in one, for connecting torque spanner.

It can be seen that self-control provided by the utility model extends allen wrench, use part common on the market into The simple assembling of row, can easily carry out the soket head cap screw for being difficult to be placed at the position of spanner inside corner, machine Twist operation, it is low in cost and effect is out of the ordinary, convenient for promoting；In addition, the utility model can be accomplished in a simple self-control, perfection, which agrees with, to be made With environment, there is splendid applicability.

It is described above to be merely exemplary for the utility model, and not restrictive, those of ordinary skill in the art Understand, without departing from the spirit and scope defined by the claims, can many modifications may be made, variation or it is equivalent, but It falls within the protection scope of the utility model.
