The electric cylinder 23 can extend the length of the extension end by controlling its power supply. This is an existing technology and will not be described in detail here.

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the base structure is arranged at the extended end of the electric cylinder 23 for supporting the main rod 20 on the ground, and the base structure includes: a bottom box 30, a bottom groove 31, a connecting column 32, an infrared head 33 and a through groove 34. The bottom box 30 is arranged at the bottom of each electric cylinder 23. The bottom box 30 is a rectangular box with a hollow cavity. The top half of the bottom box 30 and the side wall surface facing the other bottom box 30 are in an open state. The bottom groove 31 is opened at the bottom of the cavity of the bottom box 30, the connecting column 32 is fixedly connected in each bottom groove 31, the infrared head 33 is fixedly connected in the cavity of each bottom box 30, and the through groove 34 is opened on the side wall surface of the extended end of each electric cylinder 23. The infrared heads 33 in the cavities of symmetrical bottom boxes 30 can shine on each other.

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the bottom groove 31 is a rectangular groove, the connecting column 32 is cylindrical, the bottom of the extended end of the electric cylinder 23 is provided with a circular groove that can be sleeved with the connecting column 32, the through groove 34 is a rectangular groove, and the emission point of the infrared head 33 can pass through the through groove 34, and the base structure also includes a cover plate 35, a first locking groove 36, a second locking groove 37, a limiting groove 38 and a limiting rod 39, the cover plate 35 is fixedly connected to the open side wall surface of each bottom box 30 symmetrically front and back, and the first locking groove 36 is provided at each cover plate 3 located at the rear 5 top, the second locking groove 37 is opened on the top of each cover plate 35 located in the front, the limiting groove 38 is opened on the corresponding side wall surface of the electric cylinder 23 on each side, the limiting rod 39 is fixedly connected to the top opening of each bottom box 30, the cover plate 35 is a rectangular plate, the first locking groove 36 and the second locking groove 37 are rectangular notches, the limiting groove 38 is a rectangular groove, the limiting rod 39 is an L-shaped rod, and the limiting rod 39 is fixedly connected with a rectangular slider that can slide along the limiting groove 38 in the direction of the electric cylinder 23 corresponding to each side;

[0037] When in use, first place the symmetrical bottom box 30 on the ground to be tested, then start the power supply of the electric cylinder 23, so that the extension end of the electric cylinder 23 extends downward so that the level height of the main rod 20 gradually increases. When the bottom box 30 is placed on the ground, the bottom of the bottom box 30 will fit the ground, and then observe the position of the bubble in the level meter 21 to detect the level of the ground. After the bottom box 30 is placed, turn on the power supply of the infrared head 33, and the infrared head 33 on one side can emit infrared rays. The infrared rays emitted by the infrared head 33 will pass through the through slot 34 and shoot to the other infrared head 33, and the receiving If the infrared head 33 of the infrared ray can receive infrared rays, it means that the ground is flat. When the device needs to be stored after use, the extended end of the electric cylinder 23 is controlled to retract to the shortest point, and then the symmetrical fixing bolts 27 are screwed so that the bottom of the symmetrical fixing bolts 27 no longer conflicts with the wall of the main rod 20. Then, the symmetrical electric cylinders 23 are turned toward each other with the fixed axis 25 on each side as the center of the circle to the bottom of the main rod 20. At this time, the end feet of the symmetrical cover plate 35 will not conflict because of the rounded corners. When the wall of the electric cylinder 23 is turned over to fit the bottom of the main rod 20, the symmetrical cover plate 35 will block the front wall of the level 21.

[0039] like Figure 5 As shown, a top groove 40 is provided in the middle of the front wall of the main rod 20, and the top groove 40 is an arc-shaped notch with an inner wall surface. The level 21 is fixedly connected in the top groove 40.

The bottom ends of the handle 43 are respectively A cylinder that can rotate along the symmetrical connecting groove 42 is fixedly connected, a cover plate 44 is fixedly connected to the bottom opening of the handle 43, the cover plate 44 is a plate with an arc-shaped cross-section, and the outer arc surface of the cover plate 44 can fit the arc surface in the top groove 40, the level 21 is located in the inner arc surface of the cover plate 44, and the lifting and locking blocks 45 are symmetrically fixedly connected on the front wall surfaces at both ends of the bottom of the handle 43, each lifting and locking block 45 is an L-shaped block, and the lateral rear wall surface of the lifting and locking block 45 is an arc surface, and the lateral rear wall surface of the lifting and locking block 45 can fit the size in the second lock groove 37;

[0040] When in use, after the symmetrical cover plate 35 is rotated by the electric cylinder 23 to cover the front wall of the level 21, the handle 43 is turned from the back to the front with its wall cylinder as the center of the circle. As the handle 43 is turned, the lifting and locking blocks 45 can be turned synchronously. The symmetrical transverse walls of the lifting and locking blocks 45 can be inserted into the second locking grooves 37 of the cover plates 35 on each side. As the handle 43 is turned, the cover plate 44 can be driven to rotate along the top groove 40 and rotate to cover the top of the level 21. When the handle 43 is turned backward to the sticking groove 41, the lifting and locking blocks 45 will be separated from the second locking grooves 37, and the cover plate 44 will re-enter the top groove 40.

[0041] To sum up, by setting up the handle structure, not only can the lifting and moving of the device be facilitated, but the position of the cover 35 can also be automatically locked when the handle 43 is lifted, and the cover plate 44 can cover the top of the spirit level 21 as the handle 43 is lifted, so that the symmetrical cover plate 35 can protect the spirit level 21, prevent the spirit level 21 from being affected by dust and prevent the spirit level 21 from being damaged by collision.

[0042] like Figure 6 As shown, the rear wall surface of the main rod 20 is provided with a locking structure, which includes a rear plate 50, a sub-plate 51, a shifting groove 52, a rotating groove 53, a shifting block 54 and a locking shaft 55.

The locking shaft 55 is cylindrical, and the cylindrical positions of the locking shaft 55 and the wall surface of the shifting block 54 are symmetrical to each other. The first locking groove 36 can adapt to the size of the locking shaft 55.

[0043] In specific use, when the symmetrical cover plates 35 are rotated to the wall surface of the main rod 20 by the electric cylinder 23 and stored, the rear symmetrical cover plates 35 will enter the rectangular groove opened on the front wall surface of the rear plate 50. The rear plate 50 is a rectangular plate. When the cover plates 35 are completely entered into the rectangular groove on the wall surface of the rear plate 50, the shift block 54 is rotated downward to drive the lock shaft 55 to be clamped into the first lock groove 36 on each side, thereby locking the position of the cover plates 35.

[0044] In summary, by providing a locking structure, the position of the cover plate 35 can be locked by rotating the shift block 54 when the cover plate 35 is stored in the wall of the main rod 20, thereby preventing the cover plate 35 and the electric cylinder 23 from rotating on the wall of the main rod 20.

[0045] Working principle: first place the symmetrical bottom box 30 on the ground to be tested, then start the power of the electric cylinder 23, so that the extending end of the electric cylinder 23 extends downward so that the horizontal height of the main rod 20 gradually increases. When the bottom box 30 is placed on the ground, the bottom of the bottom box 30 will fit the ground, and then observe the position of the bubble in the level 21 to realize the detection of the ground level. After the bottom box 30 is placed, turn on the power of the infrared head 33. The infrared head 33 on one side can emit infrared rays. The infrared rays emitted by the infrared head 33 will pass through the through slot 34 and shoot to the other infrared head 33. If the infrared head 33 that receives infrared rays can receive infrared rays, it means that the ground is flat.
