However, the bolt adjustment is a hard connection, and there is a jamming condition when the ball head is rotated; and the whole bolt needs to be manually loosened for adjustment direction, and the direction needs to be kept unchanged for fixation, so that the adjustment and fixation of this scheme are difficult, and it is not conducive to fine laser measurement scene.
