Screw rod is distributed in the threaded hole；Corresponding offer pushes away slot below the threaded hole, it is described push away the slot upper half be it is cylindric, under
Half portion is coniform for what is gradually narrowed；It is described to push away slot and be respectively distributed half in the supporting block and the sliding shoe；It is described to push away in slot
Coniform pushing block is distributed in correspondence, and the pushing block is incorporated in the screw rod lower end；The two sides of the sliding shoe are respectively provided with clamping
Convex block, centre are clamp groove.
Further, the outside on the supporting block top is equipped with support ear.
It further, further include long orifice plate, the long orifice plate is distributed between the gripping block and the handle；The institute
State long slot hole there are two opening up on long orifice plate；For the long orifice plate in conjunction with the handle, the gripping block passes through institute by bolt
Long slot hole is stated to be fixedly connected.
Further, the sliding guide is equipped with four, is distributed in four corners of the supporting block；The corresponding cunning
Motion block also is provided with four sliding bar slots.
Further, the clamping contact face of the sliding shoe is combined with nylon sheet.
It further, further include spring, the spring one end connects the end of the sliding guide, described in other end connection
The function of pulling back to the sliding shoe is realized in the bottom end of sliding bar slot.
The present invention compared with prior art the utility model has the advantages that the present invention and is passed through by being equipped with gripping block at handle both ends
Crankshaft is fixed using the mode that clamp groove mode clamps crankshaft handle in the sliding shoe being equipped with；By be equipped with push away slot,
Pushing block, screw rod group component realize complete fastening effect, upper rotation in such a way that rotary screw is realized and pushes pressure sliding shoe under pushing block
Screw rod and easy-to-dismount mode is easy to operation, is capable of providing fastening force powerful enough simultaneously, it is ensured that crankshaft high intensity
The implementation of make-up torque keeps crankshaft to stablize, versatile.

Specific embodiment
As shown in Fig. 1~5, a kind of universal crankshaft clamp device, including handle 1 and gripping block 4；The gripping block 4 is total
There are two if, respectively corresponds and be incorporated in 1 both ends of handle；One gripping block 4 includes supporting block 4-5 and sliding shoe 4-3,
Four edges on the medial surface of the supporting block 4-5 are respectively provided on sliding guide a 4-51, the sliding shoe 4-3 corresponding
If there are four sliding bar slot 4-31；The sliding shoe 4-3 is inserted into the sliding guide 4-51 and is distributed；On the supporting block 4-5
Portion offers threaded hole, the corresponding contact surface top for being distributed in the supporting block and the sliding shoe of the threaded hole, the spiral shell
Screw rod 5 is distributed in pit；Corresponding offer pushes away slot below the threaded hole, and the slot upper half that pushes away is cylindric, lower half
It is coniform for what is gradually narrowed；It is described to push away slot and be respectively distributed half in the supporting block and the sliding shoe, that is, it is distributed in the branch
The other half for pushing away slot 4-53 and being distributed at the sliding shoe at bracer pushes away slot 4-32；Circular cone is distributed in the correspondence that pushes away in slot
The pushing block 5-1 of shape, certainly, the maximum circular diameter of the pushing block 5-1 are equal to the diameter pushed away at the upper half cylinder of slot；Such as
Sliding shoe, could be pushed open sliding by this when pushing block 5-1 is pushed down on；The pushing block 5-1 is incorporated in the lower end of the screw rod 5；Institute
The two sides for stating sliding shoe 4-3 are respectively provided with clamping convex block 4-33, and centre is clamp groove 4-1.The outside on the top the supporting block 4-5
