The present invention relates to an assistant apparatus for sitting works which can reduce fatigue of legs due to long sitting works by using an elastomer such as spring during sitting works such as farming or welding works which are performed while sitting for a long time and make the workers rise from seat easily with elastic force when the workers rise from seat after sitting works. To this end, the assistant apparatus for sitting works according to the present invention comprises a upper mount(10) which has the engagement strings(11, 21) connected to the left and right sides thereof to be mounted to a upper portion of knee joints of human body; a lower mount(20) which is formed to be corresponded to the upper mount(10) and is mounted to a lower portion of knee joints of human body; and a spring(40) which is interconnected to a lower portion of the upper mount(10) and a upper portion of the lower mount(20) by a hinge shaft(30) and provides the elastic force to the hinge shaft(30) by being connected to the upper mount(10) and the lower mount(20), wherein the upper mount(10) has a plurality of pressing grooves(17) with different depths in a contact point with the spring(40) to make the elastic force of the spring(40) be applied differently, and a plurality of springs(40) having different torsions are formed to make the pressure of the pressing grooves(17) be applied differently. |
