Abstract

PURPOSE:In a quick coupler for fitting a working device on an earthwork vehicle, to simplify the structure and to improve the operational reliability and operatability by simplifying the structure of a link mechanism, for operating a lock pin. CONSTITUTION:By expansion of the piston and the cylinder of a liquid pressure operating means 24, a lock pin 20 is retreated through the function of a link lever 23, and the upper-and lower-portion connecting members 11 and 12 of a hitch 10 are engaged with the hook portions 52 and 53 of the hooks 50 of a working device. Then, by contraction of the piston and the cylinder of the means 24, the lock pin 20 is inserted in the holes 55 formed in the middle projections 54 of the hooks 50 inserted between inside and outside support members 16 and 15, so that the hooks 50 engage the hitch 10. The boss at the tip end of a lift arm of the earthwork vehicle is swirlably fitted to a lower portion 17, and the boss at the tip end of a tilt link to an upper portion 19.
