2. quick-expansion handle device, can change the axial overall length of handle assembly, it is characterized in that comprising reel band spring, pull bar (98), pivoted housing (96), screw (97), extension spring (104), elastic memory clamping plate (103), oscillating deck (102), relatively motionless base (106), backing pin (100), axle (101), the band (105) of pull bar (98), go up pin rod (99), pin rod (107), suspension ring (109) and shake hands (108) down;
Its connection features is, described band (105) is fixed on the described pivoted housing (96) by described screw (97), described band (105) respectively with describedly go up pin rod (99), described pin rod (107), described suspension ring (109) down are connected with described handle (108); 2～99 unidirectional external tooths are arranged on the described pivoted housing (96), constitute overriding clutch; Described extension spring (104) one ends are connected with described oscillating deck (102), and the other end is connected with the described base of fixing with respect to described pull bar (98) (106);
Described axle (101) described relatively pull bars (98) are motionless;
Described coiling band spring one end is connected on the described pull bar (98), and the other end is connected on the described pivoted housing (96);
Its motion feature is that described pivoted housing (96) is gone up at described pull bar (98) and rotated; Described band (105) stretches out the direction rolling by described coiling band spring to described band (105) the shortest on described pivoted housing (96); Described oscillating deck (102) is at the constraint lower swing of described axle (101);
When discharging described handle (108), when described band (105) is arrived the most in short-term by the rolling of described coiling band spring, described pin rod (107) down makes described oscillating deck (102) enter described elastic memory clamping plate (103), draw described handle (108) down again, described oscillating deck (102) is by the pulling force of the Clamping force of described elastic memory clamping plate (103) clamping greater than described extension spring (104), and remains in the described elastic memory clamping plate (103); Can arbitrarily draw afterwards and put described handle (108), described overriding clutch is not worked and is dallied this moment;
Have only when described handle (108) is pulled out to described band (105) and stretch out when the longest, the described pin rod (99) of going up recovers by the state of the free unidirectional traction of described extension spring (104) described oscillating deck (102), described overriding clutch is started working, this moment, the application force along described coiling band spring sent described handle (108) to correct position, strain described band (105) again, just enter the monodirectional locking state;
The axial overall length of described handle assembly is prolonged, will discharge described handle (108), described handle (108) is pulled out to described band (105) is pulled out to again and stretches out when the longest, the direction of restarting to dwindle to the axial overall length of described handle assembly is regulated.
