The connecting plate is fixedly connected, and a first fixing hole is opened on the side away from the two connecting blocks 20, and the transverse parts of the two second T-shaped rods 39 are respectively inserted into the inner cavity of the adjacent first fixing holes. When the two insertion rods 18 are respectively inserted into the inner cavity of the adjacent second blind holes 17, the installation box 9 can be vertically positioned so that the laser emitting end of the laser rangefinder 10 is vertically upward, so that the height of the building can be measured. When the two second T-shaped rods 39 are pulled out of the inner cavity of the adjacent first fixing holes, the two insertion rods 18 can fall downward under the action of gravity, and the falling height can be limited by the setting of the fixing ring 19. Then, by rotating the installation box 9 and flipping it ninety degrees with the rotating shaft 8 as the center, the outer wall of the installation box 9 is fitted with the top of the insertion rod 18, so that the laser emitting end of the laser rangefinder 10 is adjusted to be horizontal, and then the length of the building can be measured.

[0026] The rolling mechanism includes four L-shaped plates 25, and the four L-shaped plates 25 are respectively hingedly arranged at the left and right corners of the storage box 1. The tops of the four L-shaped plates 25 are all penetrated and fixed with a first threaded sleeve 41, and the inner cavity of the first threaded sleeve 41 is threadedly connected with a first threaded rod 36, one end of the four first threaded rods 36 is fixedly connected to a bottom plate 37, and a universal wheel 38 is arranged on the other side of the bottom plate 37, and the other end of the four first threaded rods 36 is fixedly connected to a first rocker 6, and the L-shaped plate 25 is close to the storage box 1. A horizontal plate 32 is fixedly connected to one side of the cover 21, and a second threaded sleeve 33 is fixedly passed through the horizontal plate 32, a second threaded rod 34 is threadedly connected to the inner cavity of the second threaded sleeve 33, and a second rocker 35 is fixedly connected to one end of the second threaded rod 34, a second fixing hole matched with the second threaded rod 34 is opened on the top of the cover 21, and the other end of the second threaded rod 34 is inserted into the inner cavity of the second fixing hole, and the second threaded rod 34 is inserted into the inner cavity of the second fixing hole, so that the L-shaped plate 25 can be vertically fixed.

[0027] The cover plate 21 is provided with through grooves near the front and rear sides, and the inner cavity of the through grooves is slidably connected to the limit plates 26, the tops of the two limit plates 26 are fixedly connected to the top plates 27, and the other side of the top plates 27 is fixedly connected to the handle 28, one side of the two limit plates 26 is fitted with an L-shaped pressing plate 29, and the other side of the L-shaped pressing plate 29 is provided with a second connecting plate, the two second connecting plates are fixedly connected to the top of the cover plate 21, and the two second connecting plates are slidably connected to the cross bars 30, one end of the two cross bars 30 is fixedly connected to the adjacent L-shaped pressing plates 29, and the outer walls of the two cross bars 30 are sleeved with The third spring 31, and the two ends of the third spring 31 are fixedly connected to the second connecting plate and the L-shaped pressure plate 29 respectively. When the four L-shaped plates 25 are flipped downward in sequence, the four L-shaped pressure plates 29 can be pushed away from the adjacent limiting plates 26 first, and then the four handles 28 can be pushed to slide vertically downward in sequence, and the limiting plates 26 are made to fit with the side walls of the L-shaped plates 25, so that the L-shaped plate 25 can be flipped and limited. Then, when the L-shaped pressure plate 29 is released, the L-shaped pressure plate 29 can be slid to the top of the handle 28, and the handle 28 is vertically limited, thereby improving the stability of the universal wheel 38 when rolling.

[0028] Working principle: When the present invention is in use, first, the four second rockers 35 are rotated in sequence, and the second threaded rod 34 is screwed out of the inner cavity of the second fixing hole. Then, the four L-shaped plates 25 are flipped in sequence away from the storage box 1 and then vertically downward. When the L-shaped plates 25 are away from the cover plate 21, the two cover plates 21 can be moved away from each other under the action of the rebound force of the adjacent extrusion springs 24. Then, the four L-shaped pressing plates 29 are pushed away from the limiting plate 26 in sequence, so that the limiting plate 26 slides downward under the action of gravity, and the top plate 27 is attached to the top of the cover plate 21. The limiting plate 26 is fitted to the side of the L-shaped plate 25 away from the storage box 1. Subsequently, when the L-shaped pressing plate 29 is released, the L-shaped pressing plate 29 slides to the top of the adjacent handle 28 under the action of the rebound force of the third spring 31 and vertically limits the handle 28, thereby completing the flipping and opening of the L-shaped plate 25, which is beneficial to improving the flexibility of carrying the measuring tool. In addition, when the placement surface is uneven, the first threaded rod 36 can be driven to rotate by rotating the first rocker 6, and the height of the bottom plate 37 from the ground can be adjusted to ensure the stability of the placement of the measuring tool. Qualitatively, the height of the building can be adjusted by vertically pointing the laser emitting end of the laser rangefinder 10 upward. In addition, by starting the two hydraulic push rods 3 to jointly push the lifting plate 4 upward, the laser rangefinder 10 can be pushed to the top of the storage box 1. Then, by pulling the two second T-shaped rods 39 out of the inner cavity of the adjacent first fixing holes, the two insertion rods 18 are made to fall downward, and the laser rangefinder 10 is driven to flip synchronously by flipping the installation box 9. When the installation box 9 is flipped 90 degrees, it can just touch the top of the insertion rod 18 that has dropped to the lowest end. By adjusting the laser emitting end of the laser rangefinder 10 to a horizontal state, the length of the building can be measured, and the U-shaped plate 7 can be driven to rotate by the operation of the servo motor 5, and the rotation of the U-shaped plate 7 can drive the installation box 9 to rotate and drive the laser rangefinder 10 to rotate, so as to increase the distance measurement range, and when the laser rangefinder 10 needs to be disassembled, it is only necessary to pull the two first T-shaped rods 14 out of the adjacent first blind holes 13 cavities respectively, so that the laser rangefinder 10 can be taken out of the installation box 9, thereby improving the convenience of disassembly and assembly of the laser rangefinder 10.
