Controlled support frame to position a laser level

A controlled support frame for positioning a laser level comprising a laser head for transmitting at least one laser beam, said support frame comprising:

• a first support module including a reference element that can be positioned on a substantially planar surface,
• a second support module which is displaceable relative to the first support module and which includes a brace to support a laser-beam type level,
• engaging elements located on the first support module in a direction parallel to a longitudinal axis, the elements being arranged to cooperate with the second module,
• at least one drive element located in the second support module for driving in both directions of rotation a drive shaft for reciprocally driving at least one element along said longitudinal axis, the engaging elements of the first support module comprising at least one longitudinal contact surface for receiving and positioning said reciprocable element of the second support module, the first support module comprising at least one extensible arm rigidly joined to the reference element to increase the dimensional stability between the first support module and the surface on which it is positioned.
