[0020] In this technical solution, two groups of positioning grooves 23 are symmetrically opened on the outer side of the positioning block 14. When the positioning grooves 23 on the outer side of the positioning block 14 are rotated to align with the bottom end of the positioning protrusion 21, the elastic force of the spring 22 can automatically push the bottom end of the positioning protrusion 21 out of the adjustment groove 2 and insert it into the positioning grooves 23 on the outer side of the positioning block 14, thereby positioning and fixing the positioning block 14, solving the problem of the reverse positioning device of the existing laser plumb meter, which requires the staff to manually reverse position the laser plumb meter and has low positioning accuracy.
