DETAILED DESCRIPTION OF THE INVENTION

[0025] With reference to the illustrated drawings, this patent refers to the “UNIVERSAL SCREW WRENCH AND ITS RESPECTIVE USE”, more precisely, it conceives a screwdriver (1) of screws (12), consisting of a handle (2) or which the user holds with his hands, obtaining sufficient firmness for tightening or loosening the screw.

[0026] Said cable (2) has a hollow rod (3) at its upper end, which has a spring (11) inside, which presses an internal piston (5) activated by a button (6). The solution provides on the hollow rod (3) a removable resistance (7) heated by wires (8) and contains an encapsulation support (9), which receives the low melting temperature metal (10) and the film (17) which prevents the molten metal (10) from spilling when the tool is tilted during molding.

[0027] The invention receives the low melting temperature metal (10) and the film (17) on the encapsulation support (9). The low melting temperature metal (10) is heated through the resistance (7) that receives the external energy through the wires (8), obtaining the total melting of the metal (10) filling the square opening of the encapsulation support (9) responsible for pulling the metal (10) onto the screw (12). Then the resistance (7) is turned off, leading to the beginning of the cooling and hardening of the low melting temperature metal (10) and the film (17). After melting the metal (10), the user approaches the wrench (1) to the upper end of the screw (12) to be screwed or removed, so that the film (17) and the melted metal (10) touch each other to the cavity or shape (13) of the screw (12). Said user in turn presses the button (6), releasing the drive of the internal piston (5) on the film, pushing it on the cavity or format (13) of the screw (12) obtaining the same format. Then, the spring (11) is activated to retain the piston (5) and the user must wait until the complete cooling and hardening of the low melting temperature metal (10) and the film (17) to be used in the screw. intended.

[0028] The solution optionally contains a heating system (14) through a battery (15) located inside the cable (2), which heats the resistance (7) and energizes the switch (16), leading to interiorization wires (8), not requiring external power.

[0029] Optionally, the invention is made without the internal piston (5) and the spring (11) that performs its retraction after use, through direct exposure of the low melting temperature metal (10) and the film (17) on the encapsulation support (9), being pressed directly onto the screw, obtaining its shape.

[0030] It is certain that when the present invention is put into practice, modifications may be introduced with regard to certain details of construction and shape, without this implying a departure from the fundamental principles that are clearly substantiated in the set of claims, being it is therefore understood that the terminology used was not intended to be limiting.
