[0024] Example 3
[0025] like Figure 2 and Figure 4 As shown, in order to solve the problem that it is inconvenient to control the second threaded shaft 6 to rotate and position the ball block 2 while rotating the first threaded shaft 5 to position the device, a driven bevel gear 10 is fixedly connected to the left end of the second threaded shaft 6, and a driving bevel gear 11 is meshedly connected to the outer side of the driven bevel gear 10, and the driving bevel gear 11 is fixedly connected to the first threaded shaft 5.
