That is, the height dimension of the limit groove H111 on the slide column 111 in the vertical direction is larger than the radial dimension of the limit pin 113.

When the saddle 12 is pressed to move downwards to the limit position, the top surface of the limit groove H111 is propped against the limit pin 113, the maximum distance for the sliding column 111 to slide downwards is limited by the top surface of the limit groove H111, and when the pressure applied to the saddle 12 is removed, the elastic force of the elastic piece 14 forces the sliding column 111 and the saddle 12 thereon to move upwards, when the saddle 12 moves upwards to the limit position, the bottom surface of the limit groove H111 is propped against the limit pin 113, the maximum distance for the sliding column 111 to slide upwards is limited by the bottom surface of the limit groove H111, so that the saddle 12 can be ensured to float upwards and downwards reliably and stably, and the floating stroke is proper.
