Abstract: The invention relates to a device for transferring elements through a surface comprising a frame fastened in an opening of the surface to be crossed through and a container joined to the frame comprising at least one pair of rods joining the container to the frame on one side of the container, such that each pair of rods is made up of a first rod and a second rod, the first rod and the second rod being parallel to each other, furthermore each rod is fastened to the frame by means of a bolt on one end of each rod and to the container by means of another bolt on the opposite end of the rod such that the rods have the ability to rotate resting on the bolts.

Abstract: Rotary base for securing tools to a work table with a cylindrical support base and truncated upper end, in whose interior and concentric thereto, there is a threaded lower cover and a cylindrical base piston and with a truncated upper end with means to secure tools. The base piston is arranged on the threaded lower cover and is vertically displaced on this threaded lower cover through the interior of the support base, actuated by a lifting system between a lower unlocking position in which the base piston rotates freely around its axis with respect to the support base and an upper locking position in which the rotation of the base piston with respect to the support base is locked by means of friction of its truncated upper end against the truncated upper end of the support base.
