The specific embodiment
With reference to accompanying drawing.The utility model is provided with jockey, and described jockey comprises adapter body 1, the upper end of described adapter body 1 be provided with power output shaft in the taper shank 11 that matches of taper connection hole, described power output shaft is the rig main shaft.The tapering of taper shank 11 is according to the Morse's taper in the taper connection hole in the power output shaft;
The lower surface of described adapter body 1 extends internally and is provided with the instrument cover connecting hole 12 coaxial with taper shank 11; Described drill bit syndeton also is provided with a plurality of instrument covers 2 that match with described quick change jockey, described instrument cover has and is connected the instrument cover connection handle 21 that interporal lacuna cooperates with instrument cover, and the lower surface that described instrument overlaps extends internally to be provided with the coaxial instrument of taper shank 11 and is connected bellmouth 22; Described adapter body 1 is provided with the instrument cover locking mechanism that cooperates with described instrument cover connection handle, and it is spring marble mechanism that described instrument cover locks mechanism, and described pellet shot from a slingshot 13 can protrude in 12 neutralizations of instrument cover connecting hole and withdraw from instrument cover connecting hole 12.
Described spring marble mechanism comprises and is enclosed within the outer axial movable control cover 14 of adapter body, described adapter body 1 is provided with from the hole 15 of the sensible instrument cover of its side surface connecting hole, the described pellet shot from a slingshot 13 that setting can be moved along the hole in the described hole, described instrument cover connection handle is provided with the annular groove 23 that matches with pellet shot from a slingshot; Be provided with the inwardly motion and protrude configuration 16 in instrument cover connecting hole and ammunition feed withdraws from described instrument cover connecting hole allows bit space 17 of the described pellet shot from a slingshot of compressing in the described control cover, described jockey is provided with and makes described control cover remain on the spring 18 of lockup state, and described lockup state is the control cover 14 residing location status of pellet shot from a slingshot protrusion in instrument cover connecting hole that make.
