[0022] like Figures 1 to 5 As shown, the engineering building surveying instrument in this embodiment includes a tripod 1 and a surveying instrument body 2. Three legs 3 are installed on the tripod 1. A mounting base 4 is installed on the upper end of the tripod 1. A connecting hole 5 is provided on the upper end of the mounting base 4. A fixing component is installed inside the connecting hole 5. A connecting block 7 is installed on the lower end of the surveying instrument body 2. The connecting block 7 is located inside the connecting hole 5. When the surveying instrument body 2 and the mounting base 4 are connected, the connecting block 7 is inserted into the connecting hole 5 inside the mounting base 4 and fixed by the fixing component, thereby realizing the connection between the surveying instrument body 2 and the tripod 1. A fixing block 8 is installed on the lower end of the tripod 1 between the three legs 3. The fixing block 8 is triangular. Hook plates 9 are rotatably installed on all three surfaces of the fixing block 8. A fixing groove 10 is provided on one side of the leg 3 of the hook plate 9. When the leg 3 is stored, the hook plate 9 fixes the leg 3 through the fixing groove 10, effectively preventing the leg 3 from swinging accidentally when stored.

[0023] Specifically, the fixing assembly comprises a bidirectional screw rod 601, a threaded block 602, a clamping block 603, and a knob 604. The bottom end of the connecting hole 5 is provided with a mounting groove 11. The bidirectional screw rod 601 is rotatably installed in the mounting groove 11. The threaded block 602 is threadedly connected to the surface of the bidirectional screw rod 601 on both sides. The clamping block 603 is installed on the opposite surface of the two threaded blocks 602. The connecting block 7 is provided with a clamping groove 12 on both sides of the surface. The knob 604 is installed on one end of the bidirectional screw rod 601 through a connecting shaft. The bidirectional screw rod 601 is driven to rotate by rotating the knob 604. The bidirectional screw rod 601 drives the two threaded blocks 602 to move towards each other. The clamping block 603 at one end of the threaded block 602 is inserted into the clamping groove 12 on the connecting block 7, thereby fixing the connecting block 7.

[0024] Further, the connecting block 7 is provided with two positioning columns 13 at the lower end. The bottom end of the connecting hole 5 on both sides of the mounting groove 11 is provided with a positioning hole 14. By rotating the connecting block 7, the positioning column 13 is inserted into the positioning hole 14, thereby aligning the clamping groove 12 and the clamping block 603. The width of the mounting groove 11 is smaller than the diameter of the positioning column 13, so that the positioning column 13 does not come into contact with the bidirectional screw rod 601.

[0025] Further, the mounting seat 4 is provided with a groove 15. The knob 604 is located in the groove 15. The groove 15 effectively prevents the knob 604 from protruding outside the mounting seat 4, thereby avoiding collision of the knob 604 when the mounting seat 4 is accidentally knocked over.

[0026] Further, the fixing block 8 is provided with a mounting groove 16 on three surfaces. The mounting groove 16 is provided with a rotating shaft 17 at one end. The hook plate 9 is installed on the surface of the rotating shaft 17 through a torsional spring. The hook plate 9 remains horizontal under the action of the torsional spring. When the three supporting legs 3 are folded, the hook plate 9 fixes the supporting legs 3, thereby effectively preventing the supporting legs 3 from swinging accidentally.

[0027] Further, the triangular tripod 1 is provided with a fixing ring 18 at the lower end. The fixing ring 18 is provided with a pull rod 19 which is slidably installed in the fixing ring 18. The connecting ring 20 is installed on the surface of the pull rod 19 above the fixing ring 18. The elastic spring 21 is installed between the connecting ring 20 and the fixing ring 18. The hook plate 9 is installed on the surface of the three hook plates 9. One end of the pull rope 22 is connected to the pull rod 19. By pulling the pull rod 19, the connecting ring 20 is driven to move downwards. The pull rod 19 pulls the pull rope 22. The pull rope 22 makes the hook plate 9 inclined. Then, the hook plate 9 releases the fixing of the supporting legs 3. At the same time, the connecting ring 20 compresses the elastic spring 21. When no pressure is applied to the pull rod 19, the pull rod 19 automatically restores.

[0028] The use method of the embodiment is: when the triangular support 1 is used, first, the pull rod 19 is pulled through the gap between the supporting legs 3, the connecting ring 20 is driven to move downward by the pull rod 19, the pull rod 19 pulls the pull rope 22, the pull rope 22 pulls the hook plate 9 to be inclined, then the hook plate 9 is released from the fixing of the supporting leg 3, then the triangular support 1 is placed, when the surveying instrument body 2 and the triangular support 1 are combined, the connecting block 7 on the surveying instrument body 2 is put into the connecting hole 5 inside the mounting seat 4, the connecting block 7 is rotated to make the positioning column 13 below the connecting block 7 inserted into the positioning hole 14, then the knob 604 is rotated to drive the bidirectional screw rod 601 to rotate, the bidirectional screw rod 601 drives the two clamping blocks 603 to enter the clamping groove 12 inside the connecting block 7 through the threaded block 602, the connection of the surveying instrument body 2 and the triangular support 1 is realized, then the triangular support 1 is leveled horizontally, the surveying instrument body 2 can be used, after use, when the triangular support 1 needs to be stored, the hook plate 9 on the fixing block 8 is located in the fixing groove 10 on the supporting leg 3, the fixing of the supporting leg 3 is realized, and accidental swinging of the supporting leg 3 is effectively avoided.
