Described lever is the crank-type structure, and the galianconism end is vertical mutually with long arm end, can guarantee the sensitivity of lever double-swing, and the commutation effect.
Offer two air admission holes on the described chuck housing, be communicated with first air inlet pipe and second air inlet pipe respectively by a tracheae Connection Block, the tracheae Connection Block dynamically is hubbed on the chuck housing; Air admission hole on the chuck housing leads directly to second cylinder, and another air admission hole is communicated with first cylinder through the bottom air flue.
Described piston tube hollow bulb is pivoted with dustproof pipe, and dustproof Guan Yiduan conflicts at chuck housing inner face, and the other end is to being connected to dust cap, and dust cap locks on bottom by screw.
Described piston tube and piston space are positioned to sync-body by steady pin.
Described piston tube axis is provided with air flue, and second air inlet pipe is communicated with second cylinder through this air flue; Offer air admission hole on the bottom, first air inlet pipe is communicated with first cylinder through this air admission hole; First air inlet pipe and second air inlet pipe connect the rotation guide head.
Described piston on piston tube, forms sync-body by nut locking.
The utlity model has characteristics reasonable in design, that structure is small and exquisite, driving by lever transition piston, reach the purpose of reinforcement, under equal power, have bigger clamping force, both can be used as new power chuck and be matched on the lathe, also can reequip the power chuck of existing lathe, need not to increase the input of pneumatic equipment, can improve the processing characteristics of lathe, enlarge machined surface.
