Claims (1)

[Scope of utility model registration request] A pressing plate is pivotally attached to the bases of both ends of the cylinder and the piston rod, which are fitted to each other so as to be able to expand and contract, and the piston rod expands when pressurized by pressurized fluid injected through a coupler provided at the head of the cylinder. and a coupler for the support. In the earth retaining support operation device, the earth retaining support is comprised of an operating rod that controls the removal of a pressure fluid supply hose connected to the pressurized fluid supply hose, the discharge of the pressurized fluid, and the lifting of the support, wherein the earth retaining support protrudes outward from the pressing plate. The operating rod has an upper and a lower horizontal locking body that engages with the upper and lower surfaces of the abdomen, and a movable locking body that removably engages with the upper and side surfaces of the belly. a pressure relief portion that abuts the coupler; and a first pressure relief portion that protrudes from the pressure relief portion and abuts the inner surface of the pressure plate.
a second pressing protrusion that abuts on a movable operating portion that constitutes a part of the movable locking body and controls engagement and disengagement with the over-the-belly portion; and a third pressing portion that abuts on the over-the-belly side. An operating device for an earth retaining support, characterized in that it has a projection for use.
