[0061] The transmission shaft 701 is rotatably connected to the second shell 501 through a bearing. The bottom end of the transmission shaft 701 is located below the second shell 501 and is provided with a manual driving member. The manual driving member is a member for convenient operation by the user. The transmission shaft 701 is driven to rotate by the manual driving member. The top end of the transmission shaft 701 is located on the inner side of the second shell 501, and the top end of the transmission shaft 701 is fixedly connected with an upper end head 705. The first gear 708 is rotatably mounted on the transmission shaft 701, and the first gear 708 can slide up and down relative to the transmission shaft 701. A plurality of slots 707 distributed in a circular array are provided at the top of the first gear 708. A clamping member 706 corresponding to the slot 707 is fixedly connected to the bottom of the upper end head 705.

The first gear 708 and the transmission shaft 701 can only rotate synchronously. In this state, the user can drive the transmission shaft 701 to rotate through the manual drive member, thereby driving the first gear 708 to rotate, and the first gear 708 drives the gear ring assembly 404 to rotate to adjust the plotter installation. The seat 4 rotates; at this time, the user manipulates the button cover 711 (presses the button cover 711), and the button cover 711 pushes the first gear 708 and the transmission shaft 701 downward, overcoming the elastic support of the first spring 709, so that the first gear 708 and the transmission shaft 701 slide downward synchronously, so that the hook 717 is buckled in a certain arc portion (a section of the annular opening), and the user synchronously manipulates the surveying instrument to rotate in the first direction, and the surveying instrument rotates together with the surveying instrument mounting seat 4, and the gear ring assembly 404 rotates, driving the first gear 708 meshing therewith to rotate, and the first gear 708 The locking plate 710 is pushed to rotate in the first direction so that the hook 717 is located on one side of the notch 719 of the arc portion in the first direction. Then the user can loosen the button cover 711 and use both hands to adjust the plotter to rotate at a large angle. At this time, the plotter mounting base 4 rotates, the gear ring assembly 404 rotates, and the first gear 708 meshing therewith rotates. The first gear 708 and the transmission shaft 701 are in a clutch state and will not drive the transmission shaft 701 to rotate, so that the user can quickly adjust.

The bottom inverted spring sheet 304 is sleeved on the first thin shaft, and the bottom inverted spring sheet 304 is connected to the first thin shaft by relying on the first pressure sheet nut 305 threadedly installed on the first thin shaft. The oblique support of the bottom inverted spring sheet 304 is against the inner top of the first shell 201. The elastic force generated by the oblique support of the bottom inverted spring sheet 304 puts the bottom nut 303 and the bottom screw 301 in a stressed state, thereby avoiding the gap between the threads causing a slight shaking of the two.

[0072] A top nut 308 is fixedly installed on the inner bottom of the second shell 501, and the top screw 306 is threadedly connected to the top nut 308. A top circular groove 307 is opened at the bottom of the top screw 306, and the top of the top screw 306 is fixedly connected to the second thin shaft. The top inverted spring sheet 309 is sleeved on the second thin shaft, and the top inverted spring sheet 309 is connected to the second thin shaft by relying on the second pressure sheet nut 3010 threadedly installed on the second thin shaft. The oblique support of the top inverted spring sheet 309 rests on the inner bottom of the second shell 501.

[0073] The top of the core shaft member 3011 is interference fit with the top circular groove 307, and the bottom end of the core shaft member 3011 is fixedly connected with an end ring. The bottom end of the core shaft member 3011 is rotatably installed on the inside of the first circular groove 302 by relying on a limiting copper sleeve 3012 which is sleeved on the outside of the core shaft member 3011 and connected with the first circular groove 302 by interference fit. The middle section of the core shaft member 3011 has an elastic section, so that the core shaft member 3011 can bend slightly.

[0074] The transmission member 3014 is slidably sleeved on the core shaft member 3011, and the bottom end of the transmission member 3014 is the first friction surface, the top end of the bottom screw 301 is the friction end surface 3013, the top end of the transmission member 3014 has a hexagonal portion 3015, the rotating wheel sleeve 3016 is sleeved on the outside of the bottom screw 301 and the top screw 306, and the inner side of the rotating wheel sleeve 3016 and located between the bottom screw 301 and the top screw 306 is fixedly connected with an inner hexagonal ring 3017, the inner hexagonal ring 3017 corresponds to the hexagonal portion 3015, one end of the tilting spring assembly 3018 is fixedly connected to the core shaft member 3011, and the other end of the tilting spring assembly 3018 is slidably installed on the upper end surface of the inner hexagonal ring 3017.

[0075] like Fig.10 The spring assembly 3018 is bent downward in an arc shape, and the elastic force generated by the spring assembly 3018 pushes the rotating wheel sleeve 3016 to move downward, so that the inner hexagonal ring 3017 is sleeved on the hexagonal portion 3015, so that the rotating wheel sleeve 3016 and the transmission member 3014 can rotate synchronously, and the elastic force generated by the spring assembly 3018 pushes the rotating wheel sleeve 3016 and the transmission member 3014 downward, and the bottom end of the transmission member 3014 is squeezed on the friction end surface 3013 at the top of the bottom screw 301, so that it can drive the bottom screw 301 to rotate, so as to adjust the length of the leveling foot 3. After the leveling is completed, the user slides the rotating wheel sleeve 3016 upward, and the spring assembly 3018 is in an upward bending state after passing the horizontal state, and the elastic force generated by the spring assembly 3018 pushes the rotating wheel sleeve 3016 to move upward, so that the rotating wheel sleeve 3016 is separated from the transmission member 3014. At this time, accidentally touching the rotating wheel sleeve 3016 will not cause the length of the leveling foot 3 to change.

[0076] Specifically, Fig.12As shown, the tilt spring assembly 3018 includes: a first arc spring 301801 and a second arc spring 301802, the first end of the first arc spring 301801 is fixedly connected to the first end of the second arc spring 301802, and the first end of the first arc spring 301801 and the first end of the second arc spring 301802 are both fixedly connected to the side of the core shaft 3011, the second end of the first arc spring 301801 and the second end of the second arc spring 301802 are both provided with sliding holes, and a mounting pin 301804 fixedly connected to the upper end surface of the inner hexagonal ring 3017 is provided in the sliding hole, and a rubber pad 301803 is provided between the second end of the first arc spring 301801 and the second end of the second arc spring 301802.

[0077] The provision of the rubber pad 301803 makes the first arc spring 301801 and the second arc spring 301802 more deformable, making it easier to cross the horizontal state and change from an upward arc bend to a downward arc bend (or from a downward arc bend to an upward arc bend).

[0078] In one embodiment, the surveying instrument mounting base 4 includes: a rotating column 401, the top of which is fixedly connected with a mounting flange 402 for fixed installation with the surveying instrument, the bottom of the rotating column 401 and located below the ring gear assembly 404 is threadedly connected with a mounting nut 403, and the rotating column 401 is provided with a step portion for limiting the upward sliding of the ring gear assembly 404, and the ring gear assembly 404 is clamped and fixed by the mounting nut 403 and the step portion.
