In conjunction with shown in attached Fig. 1 and 2, a kind of lead geometrical clamp suitable for disassembling bolts, including integrally formed fixed hand Handle 1 and geometrical clamp 3 and hinged flexible handle 2 and activity folder 4, the geometrical clamp 3 press from both sides 4 hinged, the work with the activity Biconvex pin-joint piece 7, the biconvex pin-joint piece 7 and the movable hand are additionally provided between fixed handle 2 and the fixed handle 1 Handle 2 and the fixed handle 1 are respectively articulated with, and two protrusions of the biconvex pin-joint piece 7 are towards the flexible handle 2；It is described 1 tail end of fixed handle is provided with the fixed block 11 of threaded through hole, and screw thread tune is accommodated in the tapped through hole of the fixed block 11 Pole 6, the threaded adjusting bar 6 are provided with spring anchor block 61 close to one end of the biconvex pin-joint piece 7, and the spring is solid Determine to be connected with extension spring 8 between block 61 and the activity folder 4；The fixed handle 1 and the flexible handle 2 are that opening is opposite Channel, the biconvex pin-joint piece 7 includes the first protrusion 71 and second protrusion 72, and first protrusion 71 can be with the work The slot bottom of fixed handle 2 contacts, and second protrusion 72 can be contacted with the spring anchor block 61 of the threaded adjusting bar 6.

Further, the middle part of the flexible handle 2 is also hinged with miniature lever 5 by rotating bar 52, the miniature lever 5 from Rotating bar 52 extends to form arc tips 51 to the biconvex pin-joint piece 7, and the opening of the arc tips 51 is convex towards described first Play 71.

Further, the geometrical clamp 3 presss from both sides 4 with the activity and is hinged by first rotating shaft 91, the flexible handle 2 and institute It is hinged by the second shaft 92 to state activity folder 4, the biconvex pin-joint piece 7 is cut with scissors with the flexible handle 2 by third shaft 93 It connects, the biconvex pin-joint piece 7 and the fixed handle 1 are hinged by the 4th shaft 94, the first rotating shaft 91 and second turn The central point line of axis 92 presss from both sides 4 axial direction perpendicular to the activity, and the 4th shaft 94 is more leaned on compared to the third shaft 93 Nearly handle tail end.

Further, the geometrical clamp 3 and the fold-line-shaped that parallel, rear end detaches in front end of activity folder 4, the geometrical clamp 3 The installation sheet for being useful for installation shaft is also integrally formed with 4 rear ends of activity folder.

Implementation principle：

The fixed handle 1 and flexible handle 2 are the opposite channel of opening, the miniature lever 5, threaded adjusting bar 6, double Raised pin-joint piece 7, extension spring 8 are set to inside flute profile.

The position of the fixed handle 1 and the geometrical clamp 3 is constant, the first rotating shaft 91, the 4th shaft 94 position Constant, the third shaft 93 around the 4th shaft 94 is the center of circle, is that radius moves in a circle with biconvex pin-joint piece 7, institute It states flexible handle 2 to rotate for the center of circle with second shaft 92, the biconvex pin-joint piece 7 is mutually led with the flexible handle 2 System, the activity folder 4 are rotated around the first rotating shaft 91.The flexible handle 2, the biconvex pin-joint piece 7, the activity folder 4 form linkage mechanism.Pull the flexible handle 2 downwards, i.e., described 2 tail portion of flexible handle far from 1 tail portion of the fixed handle, The activity folder 4 is close to the geometrical clamp 3, can be used for clamp leads row；

As shown in Fig. 2, after the activity folder 4 and geometrical clamp 3 clamp lead, then the threaded adjusting bar 6 is adjusted, The spring anchor block 61 of the threaded adjusting bar 6 is set to resist the second protrusion 72 of the biconvex pin-joint piece 7, the biconvex hinge The arc tips 51 of the 71 contact miniature lever 5 of the first protrusion of contact pin 7 and clamping, under the limitation of the threaded adjusting bar 6, The biconvex pin-joint piece 7 and the flexible handle 2 it is mutual restrain under, the flexible handle 2, the biconvex pin-joint piece 7, Clamp position is fixed and kept to 4 formation linkage mechanism of the activity folder, can be used for gripping two pieces of drainage rows temporarily, substitutes The fastening force of bolt on drainage row makes two pieces of drainages come demolishing process mesoporous position and be aligned always, will not be by when removing bolt Bolt clamping stagnation is caused in hole position deviation, is solved during removing transformer drainage row in the prior art since lead weight is made At junction not device to hole the problem of, avoid causing bolt clamping stagnation.

After dismounting, when needing to open the activity folder 4 and geometrical clamp 3, first the threaded adjusting bar 6 is twisted outward Pine releases the limitation at the second protrusion 72, then pushes the miniature lever 5, rotates the arc tips 51, you can releases described first Limitation at protrusion 71, the fixed handle 1, flexible handle 2, geometrical clamp 3, activity folder 4 are movable, pull the activity upwards Handle 2, i.e., described 2 tail portion of flexible handle, can far from the geometrical clamp 3 close to 1 tail portion of the fixed handle, the activity folder 4 Unclamp lead.

The extension spring 8 provides the power inwardly tensed to the threaded adjusting bar 6 always, is auxiliarily fixed, and mitigates screw thread Load at mouthful, from the aspects of economy, after extension spring 8 fails, it is only necessary to extension spring 8 is replaced, and screw thread mouth loses Then fixed handle 1, geometrical clamp 3, threaded adjusting bar 6 are required for replacing effect, and the extension spring 8 is arranged for mitigating at screw thread mouth Load, reduce screw thread mouth failure probability, reduce issuable maintenance cost.

By setting the geometrical clamp 3 to the fold-line-shaped that front end is parallel, rear end detaches, the geometrical clamp 3 with activity folder 4 The installation sheet for being useful for installation shaft is also integrally formed with 4 rear ends of activity folder so that the geometrical clamp 3 is with activity folder 4 hinged Place forms notch, and the end of the lead may be housed in indentation, there, does not interfere with the geometrical clamp 3 and is closed with 4 front ends of activity folder It closes, increases the closed area of the geometrical clamp 3 and activity folder 4, enhance holding capability.

By the way that the miniature lever 5 is arranged, the first protrusion 71 for limiting the biconvex pin-joint piece 7 is further facilitated, is being beaten It is that fulcrum levers up the biconvex pin-joint piece 7 using the rotating bar 52 according to lever principle when opening, makes described first convex It plays 71 to be detached from, be easy to open.

Embodiment 2：

On the basis of embodiment 1, further, 6 tail end of threaded adjusting bar is fixedly installed adjusting knob 62, described Adjusting knob 62 is the cylinder coaxial with the threaded adjusting bar 6, and 62 side wall of the adjusting knob is uniformly parallel to axial bar shaped Decorative pattern, or be evenly equipped with diagonal line and be parallel to axial check, lozenge.

Further, the clamping face of the activity folder 4 and the geometrical clamp 3 is provided with the decorative pattern for increasing friction.

The above is only the preferred embodiment of the utility model, not does limit in any form to the utility model System, any simple modification made by the above technical examples according to the technical essence of the present invention, equivalent variations, each falls within Within the scope of protection of the utility model.
