[0028] The movable support plate 4 supports the mounting platform 1 from the lower end of the support leg 3. After the first positioning member releases the fixation of the slider 12, the slider 12 slides along the slide groove 11, and the movable support plate 4 will also move with it. The support height of the bracket structure can be changed by moving the movable support plate 4 up and down. After the movable support plate 4 is folded, the space occupied by the bracket structure will be reduced, making it easier for people to carry.

[0029] After the second positioning member is released from fixing the movable support plate 4, the movable support plate 4 can be flipped over, and the puncture feet or rubber feet at both ends of the movable support plate 4 can be switched to cope with road support in different environments, with a wide range of applications.

[0030] It is worth further explaining that the rotating pin 8 is provided through the center of the slider 12, the rotating pin 8 is rotatably connected to the slider 12, and the rotating pin 8 is fixedly connected to the movable support plate 4 at one end thereof facing the movable support plate 4. The other end of the rotating pin 8 is fixed to the second positioning member, and when the movable support plate 4 rotates, the rotating pin 8 also rotates with the second positioning member.

[0031] About the first positioning piece:

[0032] The first positioning member includes a plurality of first positioning holes 9 formed on the outside of the leg 3. Each first positioning hole 9 is evenly spaced along the length of the leg 3. The first positioning holes 9 are connected to a slide slot 11. A first positioning bolt 10 is disposed within one of the slide slots 11. The first positioning bolt 10 passes through the first positioning hole 9 and is threadedly connected to a bolt hole formed on the outside of the slider 12. To release the sliding limit of the slider 12, the first positioning bolt 10 on the outside of the leg 3 is rotated to remove the first positioning bolt 10 from the bolt hole formed on the outside of the slider 12.

[0033] About the second positioning piece:

[0034] The second positioning member includes a positioning plate 13, which is fixedly connected to the end of the rotating pin 8 away from the movable support plate 4. The positioning plate 13 is provided with a second positioning bolt 14 at both ends. The second positioning bolt 14 passes through the positioning plate 13 and is threadedly connected to a second positioning hole 15 provided on the outside of the slider 12. The second positioning bolt 14 is threadedly connected to the positioning plate 13. To release the rotation limit of the movable support plate 4, the second positioning bolts 14 at both ends of the positioning plate 13 are rotated and unscrewed from the second positioning holes 15 provided on the outside of the slider 12. The rotating pin 8 can continue to rotate, and the rotating pin 8 is fixed to the movable support plate 4, and the movable support plate 4 will also rotate accordingly.

[0035] Specifically, the handheld measuring instrument 2 is detachably connected to the upper end of the mounting platform 1 .
