<p>The tool is intended for injecting antiseptic products into a post (P). The hollow sleeve (1) serves as a reservoir for the product. The injection unit which it carries at its lower end comprises a first cylinder (8) in which there slides the piston (12) carrying the head (14) on which the spring (15) bears. A second cylinder (23) is fixed obliquely to the cylinder (8) and carries an injection needle (29') whose bearing surface (29) can swivel within the bush (27). Since the tool is fastened to the post (P), a force in the direction of the arrow (F') on the handle (1) leads to the needle penetrating the post, then the piston (12) penetrating into the cylinder (8) which expels liquid into the passage (34) of the needle after opening the valve (42). <IMAGE></p> |
