VIBRATORY INSTRUMENT INCLUDING AN INTERCHANGEABLE TOOL

摘要

The invention relates to a vibratory instrument (200) comprising a tool (220) removably mounted on a tool holder (210) intended to be mechanically and rigidly coupled to a vibration generating device. The tool (220) comprises the following elements positioned successively along a longitudinal axis: a working part (221) having a free end intended to reproduce the vibrations transmitted by the vibration generating device, a coupling portion (223), and an elastically deformable attachment part (222) disposed upstream of the coupling portion (223). The tool holder (210) comprises the following elements positioned successively along a longitudinal axis: a housing (214) that receives the attachment part (222) of the tool and a coupling bearing (215) that surrounds at least partially the coupling portion (223) of the tool (220). The external dimensions of the attachment part (222) of the tool (220) are adapted to the internal dimensions of the housing (214) in the tool holder (210), such as to prevent contact between the attachment part and the housing when the coupling portion (223) of the tool (220) is in contact with the coupling bearing (215) of the tool holder (210).
