A tool has a mechanism for absorbing energy transmitted to a hand grip, comprising a support body, a handle, an elastic return member and an interchangeable head as a base unit which is capable of accommodating additional fittings depending on the specific application. A lower part of the cylindrical body has a shouldered part having a diameter larger than its upper part so as to allow positioning and support of a ring associated with the handle. The handle has an internal shouldered part with an upper face constituting the support for the elastic return member. The interchangeable striking head comprises a part centered in the ring and a neck that fits inside an internal bore of the body. The striking head rests directly on the body in order to transmit the entire striking force to the body, and the handle extends rearwardly as the hand grip.

1. Multipurpose striking tool having a mechanism for absorbing energy transmitted to a gripping part, comprising a cylindrical support body having an internal axially extending bore, a handle including a ring at one end and a gripping part laterally spaced from the ring, an elastic return member and an interchangeable striking head, assembled as a base unit capable of accommodating additional fittings depending on a specific application, a lower part of the cylindrical support body having a shouldered part having a diameter larger than an upper part of the cylindrical support body to position and support the ring of the handle, the ring of the handle having an internal shouldered part, an upper face of the internal shouldered part supporting the elastic return member within the ring, the interchangeable striking head comprising a middle part centered in the ring and resting on the elastic return member, and a neck that fits inside the internal bore of the cylindrical support body, said striking head rests directly on the cylindrical support body in order to transmit an entire striking force to the cylindrical support body, whereby when the striking head is struck with a striking force, the elastic return member is compressed and the striking head and the cylindrical support body move relative to the ring of the handle, the elastic return member absorbing the energy transmitted to the handle, thus limiting vibration. 2. Multipurpose striking tool as claimed in claim 1, wherein the internal axially extending bore of the cylindrical support body comprises a through-bore, diameter of the shouldered part of the cylindrical support body being larger than a part underneath the shouldered part and the cylindrical support body has a groove over an entire height of the upper part which fulfils an anti-rotation function. 3. Striking tool as claimed in claim 2, wherein the handle comprises a spline, the spline penetrating into the groove on the cylindrical support body, and the internal shouldered part surrounds the upper part of the body and defines, on a horizontal upper face, a support plane for the elastic return member. 4. Striking tool as claimed in claim 1, wherein the handle comprises one or more compartments to accommodate an offset Allen key. 5. Striking tool as claimed in claim 1, wherein the elastic return member comprises a wave-spring or means that fulfils a compression function. 6. Striking tool as claimed in claim 1, wherein the striking head is interchangeable in order to allow for its possible deterioration, and comprises the middle part centered in the ring and supported and pressed against the elastic return member, and the neck is cylindrical and capable of fitting inside the internal bore of the cylindrical support body, and said striking head is elastically supported on the elastic return member and, on an upper face of the cylindrical support body. 7. Striking tool as claimed in claim 1, further including a chuck which fits on and is attached around the shouldered part of the cylindrical support body, one or more connecting screws which ensure a radial tightening of the chuck, and a cutting tool. 8. Striking tool as claimed in claim 7, further comprising openings on the cylindrical support body and on the ring of the handle for removal of waste off cuts. 9. Striking tool as claimed in claim 1, wherein for a marking application, the cylindrical support body internally accommodates a marking tool, having a marking end, and one or more screws located on an extreme flange of the cylindrical support body for ensuring positional tightening. 10. Striking tool as claimed in claim 1, wherein the gripping part of the handle is contoured to form a hand grip.
