The scissor fixture is used from the interior clip wheel tire of tension type outwardly, is ensured that three tensioning blocks 5 are balanced with tire force, is prevented Only tire slippage, while being convenient to wire drawing machine automation feeding.

Cylinder is the double action type cylinder with magnetite, and cylinder control may be implemented in the opening of one side tensioning block 5 and contraction, On the other hand institute's band magnetite by incude tensioning block 5 to tire whether stress by be in tensioning state, and fed back to control System realizes automation control.

Its operation principle of the utility model：Start the mechanical hand-motion scissor fixture of tire wiredrawing machine, control system It drives pushing block 3 to be moved upwards in clamp body slideway 41 by the double action type cylinder piston rod with magnetite and shrinks tensioning block 5, ` is right The tensioning block of fixture 5 is inserted perpendicularly on the inside of tire afterwards, then drives pushing block 3 in clamp body by double action type cylinder piston rod 16 Moved downward in slideway 41 open tensioning block 5, by cylinder institute band magnetite by incude tensioning block 5 to tire whether stress by In tensioning state, signal is fed back into control system, and then sending out instruction to cylinder makes it keep the stable tensioning state；Then Start manipulator by rim clamp maintain an equal level surely send to tire wiredrawing machine, last control system passes through 16 band of double action type cylinder piston rod Dynamic pushing block 3 moves upwards contraction tensioning block 5 in clamp body slideway 41 and unloads tire, such circulate operation.
