Adjustable hydraulic support for elements in workshop work, characterized by a support housing mouth open at the bottom, and which has a diametral notch through which passes the adjustable arm that carries the screws on the outside of fixing the element to be disassembled and manipulated. The adjustable arm is attached on the inside to the housing to a sphere of which it is radial extension. The lower part of this sphere is housed in a reworking of the upper face of a piston fitted in the inner cylindrical body of the housing. Before increasing the pressure of the hydraulic fluid acting on the lower part of the piston, the orientation of the arm can be varied since the sphere rotates like a ball joint in its concave support. By increasing the pressure of the hydraulic fluid, the sphere and therefore the arm is immobilized between its cap-shaped seat and the lateral internal edges of the upper notch of the housing.
