theodolite
望遠鏡與豎盤固連,安裝在儀器的支架上,這一部分稱為儀器的照準部,屬于儀器的上部。望遠鏡連同豎盤可繞橫軸在垂直面內轉動,望遠鏡的視準軸應與橫軸正交,橫軸應通過水盤的刻畫中心。照準部的數軸(照準部旋轉軸)插入儀器基座的軸套內,照準部可以作水平轉動。
The telescope is fixed with the vertical disk and mounted on the support of the instrument. This part is called the illumination part of the instrument and belongs to the upper part of the instrument. The telescope and the vertical disk can rotate in the vertical plane around the transverse axis. The collimation axis of the telescope should be orthogonal to the transverse axis, and the transverse axis should pass through the depiction center of the water disc. A number of axes (rotation axes) of the illumination part are inserted into the axle sleeve of the instrument base, and the illumination part can rotate horizontally.
