[0034] Working principle: When in use, the twist wheel 405 is turned, and the twist wheel 405 drives the threaded rod 403 to rotate and extend outward, so that the locking and locking of the locking parcel frame 406 on the rubber block 212 is released, and the locking frame 313 is turned to release the blocking of the locking roller 316 on the embedded groove 312, and the storage foot 201 is unfolded. When the storage foot 201 is unfolded, the synchronous bevel gear 105 is driven to rotate through the gear shaft 104. The synchronous bevel gear 105 is meshed with the adjacent synchronous bevel gears 105, so that the six synchronous bevel gears 105 rotate synchronously, so that the three gear shafts 104 drive the three storage feet 201 to rotate. The storage foot 201 is unfolded synchronously. When the storage foot 201 is unfolded, the folding main arm 302 and the folding auxiliary arm 304 are folded, and the locking block 309 and the locking groove 307 are locked, so as to prevent the storage foot 201 from changing its angle easily. Then, the locking frame 313 is moved to make the locking roller 316 fit into the embedded groove 312, so as to prevent the locking block 309 from shrinking. Then, the telescopic motor 214 is started, and the telescopic motor 214 drives the telescopic stud 215 to rotate. When the telescopic stud 215 rotates, it drives the telescopic foot 209 to extend, so as to unfold the telescopic tripod support mechanism. Then, the docking screw barrel 501 or the surveying instrument body 510 is installed on the surface of the first thread head 402 for surveying; When the earth-breaking cone 218 is used, the toggle hole 219 is toggled to rotate the support stud 217, and the earth-breaking cone 218 extends from the inside of the special-shaped screw barrel 216, so that the earth-breaking cone 218 can be used as a support and positioning; When storing, the docking screw barrel 501 or the surveying instrument body 510 is disassembled, and then the locking frame 313 is rotated to release the blocking of the locking roller 316 on the embedded groove 312, and the storage foot 201 is closed. When the storage foot 201 is closed, the synchronous bevel gear 105 is driven to rotate through the gear shaft 104. The synchronous bevel gear 105 meshes with the adjacent synchronous bevel gears 105, so that the six synchronous bevel gears 105 rotate synchronously, so that the three gear shafts 104 drive the three storage feet 201 to close synchronously, and then the torsion wheel 405 is rotated, and the torsion wheel 405 drives the threaded rod 403 to rotate and extend inward, so that the locking parcel frame 406 squeezes and locks the rubber block 212, and then the locking frame 313 is turned to make the locking roller 316 clamp into the embedded groove 312, so as to prevent the locking block 309 from shrinking and forming a locked position.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
