Embodiment Construction

[0012] figure 1 , 2 , 3, and 4 show: one end of the double-headed left and right helical bolts 2 is installed on the bottom of the reference platform 1, and the other end is installed on the base 3 with threaded holes; the lower base 7 is fixed on the reference platform 1, and the side of the lower base 7 is engraved There is a base scale line 14 with a length of 10 cm and the smallest scale in millimeters. The two ends of the lower base 7 are fixed with a bearing seat 9 and a threaded bearing seat 16 at the top. The two ends of the screw rod 10 of the lower floor are fixed on the bearing seat 9 by bearings. And on the threaded bearing seat 16 on the top, one end of the screw mandrel 10 of the lower floor stretches out and connects the scale knob 12, and the locking bolt 17 is installed on the top of the threaded bearing seat 16 on the top, and the lower base 7 is fixed with 2 and the lower floor. The screw rod 10 is parallel to the linear guide rail 8, and the screw rod 10 o...
