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
