摘要： The handpiece includes at the front a collet arranged for strongly gripping the shank of a removable tool housed in guide bores. The collet includes two or several arms attached to an annular part of the collet to grip the tool shank. Preferably, the collet arms are levers each having a support surface which is far from the jaw and on which a gripping mechanism exerts a force which is multiplied by the lever. The gripping mechanism includes a sliding sleeve having an inner conical surface which produces the force on the collet levers via balls. This arrangement enables a smaller gripping spring to be used, or such spring to be omitted. The balls of the releasing mechanism are guided in helical slots having a flexible lateral strip which holds the gripping mechanism in position via a snap fit.
摘要翻译：手柄包括在前面的夹头，其被设置用于强力地夹持容纳在引导孔中的可移除工具的柄部。夹头包括附接到夹头的环形部分以夹持工具柄的两个或几个臂。优选地，夹头臂是杠杆，每个杠杆具有远离钳口的支撑表面，并且夹紧机构施加与杠杆相乘的力。夹持机构包括具有内锥形表面的滑动套筒，其通过球在夹头杆上产生力。这种布置使得能够使用较小的夹紧弹簧，或者这种弹簧被省略。释放机构的球在具有柔性侧向条的螺旋槽中引导，该柔性侧向条通过卡扣配合将夹持机构保持就位。

摘要： At the front, a handpiece (1) has a clamp (10) fitted to tightly grip the shank of a removable tool housed in guide holes (23, 25). The clamp has two or more levers (26) attached to an annular section (22) of the clamp by elastic joints (27), each of which has a gripping jaw (20) to grip the tool shank. On each lever, the gripping jaw (20) is located much closer to the joint (27) than to a supporting surface, on which a tightening mechanism (17) exerts a centripetal force so that the lever multiplies this force. The tightening mechanism preferably has a sliding sleeve (40) having a conical inside surface (44), which produces the force at the levers of the clamp by means of balls (45) housed in the holes of a hollow rotatable shaft (11).
摘要翻译：在前部，手持件（1）具有夹紧装置（10），以紧固地夹紧容纳在引导孔（23,25）中的可拆卸工具的柄部。所述夹具具有两个或更多个杠杆（26），所述杆（26）通过弹性接头（27）附接到所述夹具的环形部分（22），每个所述杆具有夹紧所述工具柄的夹爪（20）。在每个杠杆上，夹紧爪（20）位于比支撑表面更靠近接头（27）的位置，紧固机构（17）在该支撑表面上施加向心力，使得杠杆相乘。紧固机构优选地具有具有圆锥形内表面（44）的滑动套筒（40），其通过容纳在中空可旋转轴（11）的孔中的滚珠（45）在夹子的杠杆处产生力。

摘要： A collet for holding a rotatable tool such as a bur or drill bit having a stepped shaft including a drive shaft having a stepped internal diameter mating with the external diameter of the bur or drill shaft, a plurality of hardened balls mounted in openings in the sleeve, a locking sleeve having a tapered surface movable with the force of a spring against the balls to force the balls against the shaft to lock the shaft in the sleeve. A rotatable locking collar is movable to release the spring force to release the shaft for removal and replacement of the tool.
