Abstract

A working device and an arm support (100) thereof. The arm support (100) comprises a top plate (110), a bottom plate (120), and first and second side plates (130, 140). The top plate (110) and the bottom plate (120) are oppositely disposed at an interval. The first and second side plates (130, 140) are oppositely disposed at an interval. One side and an opposite side of the first side plate (130) are provided with a first and a second bending portion (134, 136), respectively. At least a part of the first and second bending portions (134, 136) are attached and spliced to the top plate (110) and the bottom plate (120), respectively. One side and an opposite side of the second side plate (140) are provided with a third and a fourth bending portion (144, 146), respectively. At least a part of the third and fourth bending portions (144, 146) are attached and spliced to the top plate (110) and the bottom plate (120), respectively. The working device is provided with a chassis, a pump tube and the arm support (100), and adjacent arm supports (100) are hinged to one another. The arm support (100) is suitable for mass production and has low costs.
