"IMPROVEMENTS IN THE INJECTING DEVICES OF MASSIVE AND PASTOSOS PRODUCTS", characterized by the incorporation of a compact tubular body, closed frontally by a cap associated with thread, which, on the other hand, has an axial hole with internal thread for the connection of the corresponding nozzle, said body having, on its rear front face, a hole for passage of the mobile driving member and having a cavity to receive the cartridge containing the corresponding pasty product; which is injected to the outside by the action of a piston associated with a piece that, by means of a screw, is made integral with a longitudinal rod and coaxial with the described assembly, whose rod has a rack for the efficient operation of some means for driving the mobile assembly and a retention system that prevents its retraction; Likewise, at the emerging end of the rod, stop means limiting its progressive stroke are incorporated, with the previous assembly being associated with respect to a support structure, which comprises a wing acting as a handle.
