## Abstract

A tool (1) for insertion into trees comprises a first proximal end (3), a second distal end (4) and a body (2) axially extended between the first and second ends (3,4), wherein the second distal end (4) is of the cuneiform type provided with a linear edge (6) to promote the insertion of the tool (1) into a tree trunk (A), the edge being (6) linearly extended in a direction almost orthogonal to a longitudinal axis (Y) of the body (2), which is provided with a cross section (10) having a bi-convex lenticular shape.

## Claims

### Claim 1

A tool for insertion into trees comprising a first proximal end, a second distal end and a body axially extending between said first and second end said second distal end being of cuneiform type provided with a linear edge to favour the insertion of said tool into a trunk of tree, said edge being linearly extended in almost orthogonal direction to a longitudinal axis of said body, wherein said body is provided with a cross section having biconvex lenticular shape.

### Claim 2 (depends on 1)

The tool according to claim 1, wherein said body is symmetrical with respect to a plane of symmetry comprising said longitudinal axis and said edge.

### Claim 3 (depends on 1)

The tool according to claim 1, wherein a passage for a fluid to be injected or infused into said tree is obtained in said body, said passage extending from said first proximal end, and at least one opening obtained along said body.

### Claim 4 (depends on 3)

The tool according to claim 3, wherein said passage comprises a first conduit extending from said first proximal end to a second conduit communicating with said first conduit, said second conduit being transversal with respect to said longitudinal axis and extending between a pair of openings obtained along said body, said openings being distanced from said second distal end.

### Claim 5 (depends on 4)

The tool according to claim 4, wherein said body comprises two flat opposite bases extending along said longitudinal axis between said first and second end, said bases being almost orthogonal to said edge, said pair of openings being respectively obtained on said opposite bases.

### Claim 6 (depends on 5)

The tool according to claim 5, wherein said body comprises two opposite convex sides which are symmetrical with respect to said plane of symmetry, each of said sides extending from one to the other of said opposite bases.

### Claim 7 (depends on 6)

The tool according to claim 6, wherein said convex sides have respective elliptic profiles in said cross section.

### Claim 8

The device for injecting or infusing fluids into trees comprising:
an insertion tool according to one of the preceding claims,
a striker comprising a housing for said first proximal end and a free head susceptible to receiving a thrust or traction force for favouring the insertion of said tool into a trunk of tree or extracting said tool from said tree, respectively, said housing and head being almost aligned with said longitudinal axis.

### Claim 9 (depends on 8)

The device according to claim 8, wherein said striker comprises a third conduit for said fluid to be injected or infused, said third conduit communicating with said first conduit.

### Claim 10 (depends on 8)

The device according to claim 8, wherein said third conduit is inclined with respect to said longitudinal axis.
