Specific embodiment

The utility model is further described below in conjunction with the accompanying drawings：As shown in figs. 1-7, a kind of convenient pincers of road matrix Formula fixture, by suspension hook 1, steel wire rope 2；Lever 3, lever shaft 4, lever roller 5；Clamping plate upper end 6, clamping plate rotating shaft 7, clamping plate lower end 8th, carrying handle 9, spacing crossbeam 10, arm pivot post 11, crossbeam 12 are constituted；It is characterized in that：Steel wire rope is hung on crampon 1 to unload Button, shackle is made up of U-shaped semi-ring with dismountable cross bar；Shackle of the steel wire rope 2 from suspension hook 1 is passed through, and steel wire rope two ends pass through The cross bar of shackle is connected with the upper end of lever 3；Lever 3 is that sub-assembly is located at crossbeam or so two ends, one end connection suspension steel of lever 3 The shackle of cord, the other end installs lever roller 5, middle setting lever shaft 4, and is connected with clamping plate upper end 6 by lever shaft 4 Connect；Cylindrical boss is provided with the outside of the one end of 3 connecting steel wire ropes of lever 2, is easy to hang carrying handle 9；Lever roller 5 passes through Rotating shaft is fixed on the other end of lever 3, and when lever 3 is rotated, roller 5 is rolled in the top surface of crossbeam 12；Crossbeam 12 is sub-assembly, two ends Clamping plate axle bed and rotating shaft 7 are provided with, and are connected with clamping plate upper end 6 and clamping plate lower end 8 by clamping plate rotating shaft 7.

Clamping plate is that sub-assembly is symmetrically arranged at the crossbeam left and right sides, wherein play the clamping plate upper end 6 of leverage and play clamping making Clamping plate lower end 8, clamping plate upper end 6 is provided with axis hole and is connected with lever shaft 4, crossbeam rotating shaft 7 and arm pivot post 11 respectively；

Operation is easy in the upper end of carrying handle 9 for only pillar handle, and lower end is in inverted U-shaped, and its U-shaped bottom is spacing horizontal stroke Beam 10, the boss with the outer end of lever 3 coordinates, and clamping plate lower end 8 is kept open configuration；Carrying handle 9 by arm pivot post 11 with Clamping plate upper end 6 connects.

Totally 2 pairs, lever 3 and clamping plate, is symmetrically mounted on the two ends of crossbeam 12.To make clamping plate keep being taken off with workpiece when unclamping From state, facilitate pickup operation, the back side of clamping plate upper end 6 is provided with carrying handle 9, clamping plate upper end 6 when pulling carrying handle 9 Prefabricated component can therewith be climbed away with clamping plate lower end 8, rotating carrying handle 9 makes spacing crossbeam 10 hang over the circular cylindrical projection of lever 3 Lever can be blocked or left on platform.

Lever roller 5 plays reduction rubbing action.Sliding friction is changed into rolling friction, is operated more laborsaving.

When suspension ring 1 and steel wire rope 2 is pulled up, steel wire rope 2 pulls right side（It is left）Lever 3 occurs inverse around lever shaft 4 （It is suitable）Hour hands are rotated（Now lever 3 is intended to erected state）, because clamping plate upper end 6 is connected by lever shaft 4 with lever 3, Therefore the rotation drive clamping plate of lever 3 produces suitable around lever shaft 7（It is inverse）Hour hands are rotated, and realize the purpose of clamping prefabricated section.With Movable clamp is to workpiece installation site afterwards.

When needing to unclamp clamping plate, suspension ring 1 decline, and make steel wire rope 2 in relaxed state,（Now lever 3 is intended to tap-like State）, artificial carrying handle 9, clamping plate upwards climbs away prefabricated section, now because lever is in horizontal state, continuation upset lifting Handle 9, makes to be located at the cylindrical boss that the spacing crossbeam 10 on carrying handle 9 is enclosed within the end of lever 3, keeps clamping plate and prefabricated section In released state.

When fixture moves to feeding position to be needed to clamp prefabricated section again, fixture is buckled in prefabricated component top surface, upset is carried The spacing crossbeam 10 of handle 9 departs from the end of lever 3 therewith, and when 1 steel wire rope 2 of suspension ring is pulled up, prefabricated component will be pressed from both sides by clamping plate Hold.
