[0019] By Figures 1 to 5 Be given, the utility model includes support table 1, and the top of support table 1 is screw-mounted with surveying instrument 2, and the side of support table 1 is annularly and equidistantly fixedly installed with three connecting frames 3, and the middle part of connecting frame 3 is rotatably installed with shaft 4, and the surface of shaft 4 is rotatably installed with hinge joint 5, and the bottom of hinge joint 5 is fixedly installed with adjusting cylinder 6, and the inside of adjusting cylinder 6 is movably inserted with adjusting rod 7, and the bottom of three adjusting rods 7 is inserted with sharp head 8, and the top of three sharp heads 8 extends to the inside of three adjusting rods 7 and is fixedly installed with moving bar 9, and the both sides of three moving bars 9 are provided with jack 10, and the lower end of three adjusting rods 7 is equipped with elastic adjusting assembly, and the middle part of three moving bars 9 is fixedly installed with transmission pin 15.

[0020] In use, the operator adjusts the three elastic adjusting assemblies in sequence to move out of the inside of the insertion hole 10 to release the limiting, and then drives the moving strip 9 to move up through the three elastic adjusting assemblies. When the moving strip 9 moves up, the sharp head 8 is driven to move up and be stored in the inside of the adjusting rod 7. Then the operator releases the elastic adjusting assemblies, and the elastic adjusting assemblies are inserted into the inside of the insertion hole 10 to be limited by the elastic force of the elastic adjusting assemblies, so that the sharp head 8 is quickly stored and fixed in the inside of the adjusting rod 7. The sharp head 8 at the bottom of the tripod of the surveying and mapping device can be quickly and conveniently stored, so that the staff is prevented from being pricked when carrying.

[0021] The three elastic adjusting assemblies include three mounting frames 11 and six sliding sleeves 16. The three mounting frames 11 are fixedly installed at the lower parts on the one side of the three adjusting rods 7 respectively. The six sliding sleeves 16 are arranged at the middle parts on the two sides of the three adjusting rods 7 respectively. The middle parts of the three mounting frames 11 are rotatably installed with shafts 12. The surfaces of the shafts 12 are fixedly installed with transmission strips 13. One ends of the three transmission strips 13 extend into the inside of the three adjusting rods 7 respectively. The surfaces of the three transmission strips 13 are provided with transmission grooves 14. The three transmission strips 13 are sleeved on the surfaces of three transmission pins 15 through the three transmission grooves 14 respectively. The inside of the six sliding sleeves 16 is inserted with sliding rods 17. One ends of the six sliding rods 17 are fixedly connected with the middle parts on the two sides of the three adjusting rods 7 respectively. The surfaces of the sliding rods 17 are sleeved with springs 18. The two ends of the six springs 18 are fixedly connected with the sliding rods 17 and the sliding sleeves 16 respectively.

When the connecting strips 19 are pulled, the sliding sleeves 16 slide along the surfaces of the sliding rods 17 and simultaneously press the springs 18, so that the connecting strips 19 have the elastic reset effect while the stability of the movement of the connecting strips 19 is ensured. When the connecting strips 19 are pulled, the lower insertion rods 23 and the upper insertion rods 22 are moved, and the lower insertion rods 23 are moved out of the inside of the insertion hole 10 to release the limiting.

[0023] Then the operator presses one end of the transmission bar 13 to rotate downward along the rotating shaft 12 on the mounting frame 11, so that the other end of the transmission bar 13 rotates upward, and when the other end of the transmission bar 13 rotates upward, it can drive the moving bar 9 to move upward through the cooperation of the transmission groove 14 and the transmission pin 15. When the moving bar 9 moves upward, it drives the sharp head 8 to retract into the inside of the adjusting rod 7. Then the operator releases the handle 21, so that under the elastic force of the spring 18, the connecting rod 19 is pushed to move to reset through the sliding sleeve 16. When the connecting rod 19 moves to reset, it drives the upper insertion rod 22 to insert into the inside of the insertion hole 10 for limiting, so as to quickly retract and fix the sharp head 8 in the inside of the adjusting rod 7.
