This embodiment includes handle 1, decide lip 2, both sides face homoenergetic and decide lip 2 complex moving lip 3 and be used for moving the regulation lead screw 4 that the 3 strokes of lip were adjusted, decide lip 2 set up at handle 1 front end and with handle 1 structure as an organic whole, handle 1's front end is equipped with the through-hole that is used for the installation to adjust lead screw 4, move lip 3 sets up the opposite side at deciding lip 2, the both sides face of moving lip 3 is smooth surface 31 and sawtooth surface 32 respectively, the lower extreme of moving lip 3 is equipped with and adjusts 4 complex meshing teeth of lead screw, decide 2 front ends of lip and be provided with convex tup 5. The above is the structure existing in the prior art, and is not described in detail herein.

The utility model discloses an innovation point lies in:

shown in the attached drawings 1-4, with 2 one sides of fixed lip that move lip 3 complex have 120 degrees interior angles, the smooth surface 31 area of moving lip 3 also has 120 degrees interior angles, the angular bisector coincidence of two interior angles, so when screwing the nut, two faces of 2 interior angles of fixed lip and two faces of 3 interior angles of moving lip all support and lean on the nut, so when screwing the nut, have 4 with the nut contact surface at least, compare only two stress surfaces with current spanner, the lifting surface area of nut has been increased, can go on torsion dispersion to more stress surfaces, so the rotation in-process is difficult for skidding more, be favorable to reducing nut or bolt surface damage degree, promote the reuse rate of nut or bolt. If only one moving lip 3 is arranged in the scheme, the small hexagon nut or the bolt cannot be clamped and cannot rotate, so that the application range of the application is widened, the small moving lip 6 is inserted into the moving lip 3, the small moving lip 6 can still approach the fixed lip 2 after the moving lip 3 approaches the fixed lip 2 to the limit, then the small moving lip 6 and the fixed lip 2 can clamp nuts of smaller models, the outer leakage surface of the small moving lip 6 is flat with the smooth surface 31 of the moving lip 3, when the small moving lip 6 is not needed, the small moving lip 6 is completely embedded into the moving lip 3, the inner angle positions of the small moving lip 6 and the moving lip 3 are the same, the angle is the same, the purpose is perfect to be matched with the fixed lip 2, the hexagonal nut or the bolt is occluded, the ridge part of the small moving lip 6 is fixedly connected with the sliding rod 7, the sliding rod 7 and the small moving lip 6 can slide in the moving lip 3, the sliding rod 7 is a non-cylindrical body, the small movable lip 6 and the sliding rod 7 only slide in the movable lip 3 and do not rotate, so that the situation that the small movable lip 6 cannot clamp the nut easily due to twisting is prevented, two locking holes are machined in the sliding rod 7 and are respectively called as a locking hole A8 and a locking hole B9, magnets are respectively arranged on the inner sides of the locking hole A8 and the locking hole B9, a jack 10 matched with the locking hole is machined in the corresponding movable lip 3, and a steel lock pin 11 is inserted in the jack 10 in a sliding mode. When the screwed nut is large in size and does not need the small movable lip 6, the small movable lip 6 is inserted into the movable lip 3, the inserting hole 10 is coaxial with the locking hole A8, the locking pin 11 is inserted into the inserting hole 10 and the locking hole A8, the sliding of the small movable lip 6 is limited, and the locking pin 11 can be attracted by a magnet in the locking hole, so that the locking pin is convenient to fix and is prevented from being lost; when the size of the screwed piece nut is small and the small movable lip 6 is needed, the small movable lip 6 extends out of the movable lip 3, the inserting hole 10 is coaxial with the locking hole B9, the locking pin 11 is installed in the inserting hole 10 and the locking hole B9 in a differential mode, the sliding of the small movable lip 6 is limited, the free end of the movable rod 7 is contracted in the sawtooth surface 32 at the moment, the sawtooth surface 32 is not prevented from playing a clamping role, and the opening size of the small movable lip 6 and the opening size of the fixed lip 2 can be adjusted through the adjusting screw rod 4.

With 2 inboards of the relative fixed lip of moving lip 3 have and are used for preventing to revolve the strong magnet 12 that the piece dropped, the utility model discloses more be fit for high altitude dismouting nut or bolt, after nut or bolt are unscrewed, under the magnetic attraction effect of strong magnet 12 in fixed lip 2, nut or bolt can not take place to drop, avoid follow-up unnecessary troublesome, are favorable to promoting work efficiency.

The handle 1 turn clockwise or anticlockwise for 90 degrees instantly, the handle 1 width direction mutually perpendicular of the two sides of the turning point increases the contact area of the tail end of the handle 1 and a palm, reduces the pain of the hand, enables a worker to apply larger rotary force, and is favorable for improving the fastening effect of a nut or a bolt.

The handle 1 is provided with scales which can be used as a graduated scale when needed.

The handle is characterized in that a through hole 13 is formed in the thickness direction of the tail end of the handle 1, a wrench mounting plate 14 is hinged in the through hole 13, a ratchet socket wrench 15 is fixedly connected to the wrench mounting plate 14, the axis of the ratchet socket wrench 15 is perpendicular to the wrench mounting plate 14, coaxial positioning holes 16 are respectively formed in the thickness surface of the handle 1 and the thickness surface of the wrench mounting plate 14, a positioning pin 17 for positioning the wrench mounting plate 14 is inserted in the positioning hole 16 in a sliding manner, a hole expanding part 18 is arranged in the middle of the positioning hole 16, a steel limiting ring 19 is fixedly connected to the positioning pin 17 of the hole expanding part 18 for limiting the axial displacement of the positioning pin 17, magnets are respectively arranged in the hole expanding parts 18 at the upper end and the lower end of the limiting ring 19, and the limiting ring 19 is attracted to the upper end or the lower end of the hole expanding part 18, the positioning pin 17 leaves the positioning hole 16 of the wrench mounting plate 14, so that the positioning function of the wrench mounting plate 14 is lost, the ratchet socket wrench 15 can rotate, and the ratchet socket wrench 15 is prevented from pressing against hands and being incapable of applying torque; when the limiting ring 19 is sucked at the lower end of the hole expanding part 18, the positioning pin 17 is inserted into the positioning hole 16 of the wrench mounting plate 14 to further position the wrench mounting plate 14, so that the ratchet socket wrench 15 cannot rotate, the nut or bolt in a narrow space can be conveniently screwed by the socket wrench in the next step, the ratchet socket wrench 15 needs to be locked, the problem that one person cannot operate due to the fact that the number of movable joints is too large is solved because the other hand of a worker mainly controls a sleeve with the movable joints when the socket wrench with the movable joints is connected in the next step, direction control on the ratchet socket wrench 15 is not needed, and the problem that one person cannot operate due to the fact that the number of the movable joints.

Handle 1 on process and to have the box spanner mouth that the size is different, increase the application scope of this application, make this application more multi-functional.
