Abstract

A handle connection for a manual utensil or tool, whereby the implement (2) has a biconical through-hole and there is a handle head (1) on the handle with an exterior surface that matches the surface of the hole in which it is inset. The handle head (1) presents an interior hole (40), at the outlet (31) of which in the outgoing angle zone (Z2) there is a wedge (5) that, when pressure is applied to this outgoing angle zone (Z2), makes the zone fit flush with the hole. It has a fastening screw (7), the body of which (16) passes through the wedge (5), and it is screwed by threads (15 and 151) directly/indirectly to the head of the handle (1), which screw has a head (9) that directly/indirectly abuts against the implement (2) such that the head of the handle (1) works like a nut with respect to the fastening screw (7).

Dependent claims

A handle connection for a manual utensil or tool, comprising:

a) a handle (1) for an implement (2), said handle having a non-metallic head;
b) the implement (2) has a hole (11) in which the head of the handle (1) is inset, thereby leaving the end surface (X) of this handle head (1) free;
c) a third, metallic and non-deformable element (3) that is fastened to the top of the head of the handle (1), thereby partially occupying a transversal section of the head of the handle and being completely contained within the head of the handle;
and
d) a fastening screw (7), the body 16 of which is connected to the third element and the screw (7) has a head (9) that abuts against the implement (2), thereby establishing a male-female relationship between the third element (3) and the fastening screw (7) such that the third element (3) can move longitudinally, thus pulling the head of the handle (1) with it and thereby insetting the handle into the hole (11) of the implement (2).
