Specific embodiment
The utility model is described in further details below in conjunction with attached drawing.
As depicted in figs. 1 and 2, the magic chuck of the utility model includes the pedestal 1 of tubular, and the oral area of the pedestal 1 is downward.
Its main feature is that having through-hole on corresponding 1 side wall of pedestal in a radial line both ends of the pedestal 1.Have in the through-hole quickly
Fixed mechanism, mechanism for quick fixing include horizontally disposed support tube 3, and support tube 3 is located in corresponding through-hole, support tube 3
Nozzle has centre bore on the cylinder bottom of support tube 3 towards 1 inner cavity of pedestal, there is connecting rod 5 in centre bore, and one end of connecting rod 5 is located at branch
It supports in cylinder 3, the other end is located at outside support tube 3, in sliding shape cooperation between the cylinder bottom of connecting rod 5 and support tube 3, is located in support tube 3
5 one end of connecting rod be provided with limited post 7, in being arranged concentrically between limited post 7 and support tube 3, and be between limited post 7 and support tube 3
Shape cooperation is slided, there is compressed spring 6 between limited post 7 and the cylinder bottom of support tube 3, compressed spring 6 is under relaxation state, far from even
The nozzle that 7 one end of limited post of bar 5 passes through support tube 3 is extend into pedestal 1.
