The clamping seat 5 is relatively slidably installed on the outer wall of the upper side of the driving box 3, a tension spring 20 is arranged between the two clamping seats 5, and the outer walls of the surveying instrument 6 on opposite sides are respectively connected to the clamping seat 5. A base groove 14 is arranged at one end of the support rod 2 opposite to the base 1, a groove 15 is arranged on the base groove 14, and a slide groove 16 is arranged on the outer walls on opposite sides of the groove 15, and the support rod 2 is movably installed in the slide groove 16. When in use, first pull the clamping seat 5. The two clamping seats 5 are symmetrically installed on the outer wall of the upper side of the driving box 3. A cavity for installing the tension spring 20 is provided on the outer wall of the upper side of the driving box 3, and an extension rod is provided at the lower end of the clamping seat 5. The extension rod is located in the cavity. The two ends of the tension spring 20 are respectively connected to the extension rod. The clamping seat 5 slides on the outer wall of the upper side of the driving box 3. After the surveying instrument 6 is fixed between the two clamping seats 5, the force on the clamping seat 5 can be ended. Then, the base groove 14 provided at one end of the support rod 2 is flipped to be level with the ground and fixed. Then, the support rod 2 is driven to rotate a predetermined angle through the driving component 4. Specifically, the bevel gear 2 8 is rotated horizontally to drive the bevel gear 1 7 to rotate vertically, thereby driving the threaded rod 9 to rotate. One end of the threaded rod 9 drives the threaded seat 10 to slide up and down, thereby driving the connection angle between the connecting rod 11 and the support rod 2 to deflect, thereby driving the support rod 2 to rotate outward along the hinge point with the base 1, so that the lower end of the support rod 2 slides in the base groove 14, and the support rod 2 is adjusted in different positions in the slide groove 16 to adjust the angle of rotation of the support rod 2 driven by the threaded seat 10, so as to achieve different height adjustments, thereby achieving the purpose of adjusting the height of the surveying instrument 6 installed on the upper side of the base 1.

[0021] Specifically, the driving assembly 4 includes a bevel gear 1 7, a bevel gear 2 8 and a threaded rod 9. The bevel gear 1 7 is rotatably mounted at the axis of the base 1. The bevel gear 2 8 meshes with the bevel gear 1 7. The bevel gear 1 7 meshes with the bevel gear 2 8. The bevel gear 2 8 is rotatably mounted on the inner wall of one side of the driving box 3. The threaded rod 9 is fixedly connected to the bevel gear 1 7. The driving assembly 4 also includes a threaded seat 10 and a connecting rod 11.

One end of the connecting rod 11 is rotatably connected to the mounting port 12. A connecting port 13 is provided on one side of the support rod 2. The other end of the connecting rod 11 is hinged to the connecting port 13. Please refer to the attached Figure 2 and Figure 4As shown, when in use, the bevel gear 2 8 can be extended to one end of the outer wall of the drive box 3 by rotating, driving the bevel gear 1 7 to rotate vertically, thereby driving the threaded rod 9 to rotate. One end of the threaded rod 9 drives the threaded seat 10 to slide up and down, so as to drive the connection angle between the connecting rod 11 and the threaded seat 10 to deflect, and the other end drives the angle of the support rod 2 to change, thereby driving the support rod 2 to rotate outward along the hinge point with the base 1, so as to adjust the angle of the support rod 2 driven by the threaded seat 10 to achieve adjustment of different heights.

[0022] Specifically, an elastic key 17 is provided in the groove 15, and fixing grooves 18 are provided on the outer walls of the opposite sides of the support rod 2, and the elastic key 17 is slidably installed in the fixing groove 18.

Figure 3 or Figure 4 As shown, when in use, the base groove 14 is pulled outwards respectively, so that the elastic keys 17 on the inner walls on both sides of the groove 15 are free from the resistance of the notches set in the fixing groove 18, slide out of the fixing groove 18, and fixed on the ground. The outer wall at the lower side of the base groove 14 is provided with fixing nails 19 for fixing the base groove 14 on the soil surface. After the base groove 14 is fixed by the fixing nails 19, the base 1 can also be fixed accordingly. Then, under the driving action of the driving component 4, the support rod 2 is driven to slide in different positions of the slide groove 16 respectively until it reaches a predetermined height, and then the rotation of the bevel gear 2 8 is stopped to fix the support rod 2. The operation on the bevel gear 2 8 is repeated. To achieve multiple height adjustments, and through the contact between the bottom surface of the base groove and the ground, the force can be evenly distributed to ensure stability during use. After use, the outwardly extended support rod 2 can be folded, and after the support rod 2 is folded, one end of the support rod 2 is pulled to one end of the slide groove 16, and the base groove 14 is rotated until the groove 15 is in contact with the support rod 2. At this time, the elastic key 17 will slide along the fixing groove 18 to one end of the fixing groove 18. A notch is provided at one end of the fixing groove 18. One end of the elastic key 17 is restricted by the notch to fix the base groove 14, and slides out of the notch after a certain force is applied for use.
