Title:
ATTACHMENT DETACHABLE MECHANISM AND WORK MACHINE
Document Type and Number:
Japanese Patent JP2019132016
Kind Code:
A
Abstract:
To ensure stable and good workability while a work attachment can be freely attached and detached.SOLUTION: In an attachment detachable mechanism 140, a work attachment 150 is provided with two pairs of support holes 152 and 154 that are separated from each other in the swinging direction of the work attachment and that make a pair in the axial direction O perpendicular to the swinging direction. In tip portions 132A and 136B (connecting portions of an arm body 127) disposed between the two pairs of support holes 152 and 154, pin expansion and contraction mechanisms 140A and 140B including two pairs of pins 142A and 142B that are separated and approached in the axial direction O and linear motion mechanisms 144A and 144B that support the two pairs of pins 142A and 142B are incorporated. When the pin expansion and contraction mechanisms 140A and 140B drive the two pairs of pins 142A and 142B away from each other, the pins 142A and 142B are inserted into the support holes 152 and 154, respectively.SELECTED DRAWING: Figure 2
