All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The first embodiment is as follows:

referring to fig. 1 and 3, a foot rest for surveying and mapping includes a lifting device 8, two sides of the lifting device 8 are movably hinged with a support rod 81, a spring 82 is movably sleeved above the support rod 81, a connecting rod 83 is movably hinged below the support rod 81, the support rod 81 penetrates through the lower part of a fixed plate 7 and is hinged with the connecting rod 83, and the support rod 81 between the fixed plate 7 and a movable plate 6 is sleeved with the spring 82. A rotating wheel 84 is movably arranged on one side of the connecting rod 83 far away from the supporting rod 81. The front side of the rotating wheel 84 is movably hinged with a ratchet gear, a limit rod is arranged above the ratchet gear, and a poke rod is arranged on the front side of the ratchet gear.

Still include bottom plate 1, the top fixed mounting of bottom plate 1 has guard box 2, and sponge material is installed to the inner wall of guard box 2. The inside fixed mounting of guard box 2 has surveying instrument 4, and the top activity of guard box 2 articulates there is installation lid 5, and the below fixed mounting of surveying instrument 4 has fly leaf 6, and the below fixed mounting of fly leaf 6 has fixed plate 7.

Example two:

referring to fig. 1-2, a supporting stand for surveying and mapping further includes a bottom plate 1, a protection box 2 is fixedly installed above the bottom plate 1, and a sponge material is installed on the inner wall of the protection box 2. The inside fixed mounting of guard box 2 has surveying instrument 4, and the top activity of guard box 2 articulates there is installation lid 5, and the below fixed mounting of surveying instrument 4 has fly leaf 6, and the below fixed mounting of fly leaf 6 has fixed plate 7.

The support device 3 is movably mounted below the bottom plate 1, swing rods 31 are movably mounted on two sides of the support device 3, a support rod 32 is fixedly mounted in the middle of the swing rod 31, a moving block 33 is movably mounted in the middle of the support rod 32, and rotating rods 34 are movably hinged to the left side and the right side of the moving block 33. The upper part of the swing rod 31 is hinged with the bottom plate 1, and the lower part of the swing rod 31 is hinged with one end far away from the rotating rod 34.

Example three:

referring to fig. 1-3, a foot rest for surveying and mapping includes a lifting device 8, two sides of the lifting device 8 are movably hinged with a support rod 81, a spring 82 is movably sleeved above the support rod 81, a connecting rod 83 is movably hinged below the support rod 81, the support rod 81 penetrates through the lower part of a fixed plate 7 and is hinged with the connecting rod 83, and the support rod 81 between the fixed plate 7 and a movable plate 6 is sleeved with the spring 82. A rotating wheel 84 is movably arranged on one side of the connecting rod 83 far away from the supporting rod 81. The front side of the rotating wheel 84 is movably hinged with a ratchet gear, a limit rod is arranged above the ratchet gear, and a poke rod is arranged on the front side of the ratchet gear.

The working principle is that the upper part of the swing rod 31 is hinged with the bottom plate 1, the lower part of the swing rod 31 is hinged with one end far away from the rotating rod 34, at the moment, the moving block 33 moves downwards in the supporting rod 32, so that the rotating rod 34 rotates inwards, the rotating rod 34 pushes the swing rod 31 to rotate outwards, and a triangular shape is formed between the swing rods 31, so that the placing is more stable.

Because the front side activity of runner 84 articulates there is the ratchet wheel, and the top of ratchet wheel is provided with the gag lever post, and the front side of ratchet wheel is provided with the poker rod, and the gag lever post is kept away from the ratchet wheel, stirs the poker rod and makes runner 84 drive connecting rod 83 when outwards rotating, and connecting rod 83 pulling bracing piece 81 moves down. Because the bracing piece 81 runs through fixed plate 7 below and is articulated with connecting rod 83, cup joint spring 82 between the bracing piece 81 between fixed plate 7 and the fly leaf 6, so spring 82 is compressed, and bracing piece 81 drives fly leaf 6 downstream, and fly leaf 6 pulling surveying instrument 4 downstream, and sponge material is installed to the inner wall of guard box 2, and sponge material in the case protects surveying instrument 4, and the stopper rod card prevents it from reversing among the ratchet gear wheel thereupon.

In conclusion, the supporting leg frame for surveying and mapping moves downwards in the center of the supporting rod 32 through the moving block 33, at the moment, the supporting rod 32 stretches out, the swinging rod 31 is pushed to form a triangular pyramid, the stability of the supporting leg frame during placement is improved, the contraction mode is simple, and the carrying is convenient.

This foot rest of survey and drawing usefulness drives runner 84 through the poker rod and rotates for connecting rod 83 outwards rotates, pulling bracing piece 81 downstream, and bracing piece 81 drives fly leaf 6, surveying instrument 4 downstream, and surveying instrument 4 falls to protection box 2 in, and sponge material in the case cushions undulant, guarantees that the instrument avoids the physics to collide, guarantees surveying instrument 4 measured data's accuracy.
