    • The jointed stand comprises two joint or swivel heads coupled to each other and two arms each extending from a related one of the joint heads and terminating in a respective ball-and-socket joint. Each ball-and-socket joint is operatively associated with a push or thrust rod which slidably extends through the related arm and cooperates with a related transmission or transfer member in the associated joint or swivel head. Each transfer or displacement member has two oppositely inclined surfaces on opposite sides thereof which are supported at an associated end of the related push rod and at the joint head, respectively, by means of roller bodies. A hinge pin extends through the transmission members with clearance. A tightening element coacts with the hinge pin in order to be able to cam the transmission members at the roller bodies, so as to be able to selectively positively lock in place the arms and ball-and-socket joints and, when desired, to quickly release such locking action.
    • 接合支架包括彼此联接的两个接头或旋转头和两个臂,每个臂从相关的一个接头头延伸并终止在相应的球窝接头中。 每个球窝接头可操作地与推动杆或推杆连接,推杆或推杆可滑动地延伸通过相关臂并与相关联的接头或旋转头中的相关变速器或转移构件配合。 每个传送或位移构件在其相对侧上具有两个相对倾斜的表面,它们分别通过辊体支撑在相关推杆的相关联的端部处和在接头处。 铰链销以间隙延伸穿过传动构件。 紧固元件与铰链销共同作用,以便能够在辊体上凸轮传动件,以便能够选择性地将臂和球窝接头以及当需要快速地锁定在适当位置时 释放这种锁定动作。

    • A revolving fixture intended to support tools or instruments is described. Said fixture comprises first elements for the connection to a carrying structure, and second elements adapted to lock the said tool or instrument and rotatable relative to the said first elements about a main axis.The main feature of this fixture is to comprise means apt to adjust, in a relatively precise, responsive and stable manner, the position of the said tool or instrument with respect to the said axis, so as to position the tip of the said tool or instrument in such a manner as to make it substantially coincide with a point of the said main axis and thus minimize the deviations of the tip of the tool or instrument from the said main axis during the rotation of the said second elements relative to the said first elements.
    • 描述了用于支持工具或仪器的旋转夹具。 所述夹具包括用于连接到承载结构的第一元件,以及适于锁定所述工具或器具并且相对于所述第一元件围绕主轴线可旋转的第二元件。 该夹具的主要特征在于包括能够以相对精确的响应和稳定的方式调整所述工具或器械相对于所述轴线的位置的装置,以便定位所述工具的尖端或 仪器以使其基本上与所述主轴线的点重合,从而使所述工具或仪器的尖端与所述主轴线在所述第二元件相对于所述第一主轴线旋转期间的偏差最小化 元素。
