Bead breaker device

A bead breaker device (1) comprising: an arm (2) able to slide horizontally along a sliding axis (X-X), in a pipe (3) supported so that it can slide vertically on a post (4) projecting cantilevered from a base; an orientable bead breaker tool (10) associated with an end of said arm (2) and suitable for breaking the bead of a tire of a wheel removably fixed onto rotary support and locking means of the rim; actuation means (14, 15, 17) suitable for orienting said tool (10) between a first thrusting configuration and a second penetration configuration, where said actuation means (14, 15, 17) comprise a thrusting body (14) and elastic means (17) cooperating with said tool (10), said thrusting body (14) being able to be actuated between a first extension position in contrast to the action of said elastic means (17) and a second release position in which the force exerted by said elastic means (17) prevails.
