The limited fixing member 203 is fixedly connected to the inner side of the adjusting installation ring 201, and is limitedly moved inside the limited plug rod 1034; the adjusting fixing member 202 02 includes an adjusting screw 2021 and an adjusting push rod 2022 connected to one end of the adjusting screw 2021, and an adjusting block 2023 is arranged on the other side of the adjusting push rod 2022, and a return spring 2024 is arranged on the outside of the adjusting push rod 2022, wherein the adjusting screw 2021 is connected to the adjusting mounting ring 201 in a threaded manner, and a limiting ring is connected to the outside of the adjusting screw 2021, and the adjusting screw 2021 and the adjusting push rod 2022 are connected by welding and fixing, and the adjusting block 2023 is limitedly moved inside the adjusting mounting ring 201, and one side of the adjusting block 2023 is engaged with a slot opened inside the limiting fixing slot 1032.

The support rod assembly 300 includes a support sleeve rod 301 and a first rotatable connecting rod 302 connected to one end of the support sleeve rod 301, and a support rod member 303 is connected to the inside of the support sleeve rod 301, and a limit ring set 304 is installed on the outside of the support sleeve rod 301, and a second rotatable connecting rod 305 is connected to the support sleeve rod 301, wherein a base for rotatable connection is connected to the support sleeve rod 301, and rotates between the second rotatable connecting rod 305, and at the same time, the other end of the second rotatable connecting rod 305 is rotatably connected to a rotatable connecting base provided inside the folding groove 1012, and the first rotatable connecting rod 302 is fixedly connected to the support sleeve rod 301, and at the same time, one end of the first rotatable connecting rod 302 is rotatably connected to a rotatable connecting base provided on the adjusting mounting ring 201, and the support rod member 303 is installed inside the support sleeve rod 301 and can move inside the support sleeve rod 301;

The support rod 303 includes a support rod body 3031 and a movable connecting rod 3032 connected to one end of the support rod body 3031, and a thrust spring 3033 is provided at the other end of the movable connecting rod 3032, wherein the support rod body 3031 and the movable connecting rod 3032 are connected in a fixed manner, and the cross-sectional shape of the movable connecting rod 3032 is a regular hexagon; the limiting ring kit 304 includes a limiting ring sleeve body 3041 and a rotating stop block 3042 arranged on the inner side of the limiting ring sleeve body 3041, and the rotating stop block 3042 is rotatably connected to the inside of the support sleeve rod 301, wherein the limiting ring sleeve body 3041 is sleeved on the telescopic rod 401, and the limiting ring sleeve body 3041 and the support sleeve rod 301 are connected in a threaded manner, and the rotating stop block 3042 is connected to the inside of the support sleeve rod 301 by a rotational connection, so that the rotating stop block 3042 can rotate in a small range around the rotation connection.

When not in use, the bracket can be folded and stored for easy carrying and movement. When in use, first rotate the adjusting screw 2021, and use the threaded connection between the adjusting screw 2021 and the adjusting mounting ring 201 to move the adjusting screw 2021 outward. At the same time, the limiting ring structure provided on the adjusting screw 2021 can ensure that the adjusting screw 2021 will not fall off and prevent it from being lost. Since the adjusting screw 2021 moves outward, the adjusting rod 222 will not press against the adjusting block 2023, and the adjusting mounting ring 201 can be moved downward. When the adjusting mounting ring 201 moves downward, The adjusting block 2023 moves inside the limiting fixing groove 1032 until the adjusting mounting ring 201 finishes moving. Then, the adjusting block 2023 engages with the groove located at the lower side of the limiting fixing groove 1032 under the action of the return spring 2024. Then, the adjusting screw 2021 is rotated again to make the adjusting screw 2021 drive the adjusting push rod 2022 to move, thereby making the adjusting push rod 2022 press against the adjusting block 2023 to prevent the adjusting block 2023 from moving. The adjusting block 2023 can be engaged with the groove at the lower side of the limiting fixing groove 1032 to complete the limiting fixation of the position of the adjusting mounting ring 201.

When the adjusting mounting ring 201 moves downward, due to the rotating connection between the adjusting mounting ring 201 and the first rotating connecting rod 302, and the rotating connection between the supporting sleeve rod 301 and the second rotating connecting rod 305, and the second rotating connecting rod 305 and the main sleeve rod 101, the supporting sleeve rod 301 can be rotated, and then the support rod assembly 300 is spread apart, and the four groups of support rod assemblies 300 arranged at equal angles are used to complete the support and fixation of the bracket; when used on some uneven terrains, the four groups of support rod assemblies 300 cannot complete the support of the bracket. At this time, through the setting of the limiting ring kit 304, the limiting ring sleeve body 3041 is rotated to move the limiting ring sleeve body 3041 to move the position, and the restriction of the limiting ring sleeve body 3041 on the rotating block 3042 is loosened, so that the support rod 303 can move inside the supporting sleeve rod 301 When the ground is uneven, the support rod body 3031 and the movable connecting rod 3032 extend outward under the action of the thrust spring 3033, so that the support rod body 3031 is against the ground. At the same time, the positions of the four groups of support rod bodies 3031 are adjusted respectively. After ensuring the support is stable, the limiting ring sleeve body 3041 can be rotated again to make it move and push the rotating stop block 3042 to rotate again, and limit the movement of the rotating stop block 3042. Since the cross-section of the movable connecting rod 3032 is a regular hexagon, the rotating stop block 3042 presses against one side of the movable connecting rod 3032. At the same time, due to the limitation of the limiting ring sleeve body 3041, the movable connecting rod 3032 can be clamped to prevent it from moving, thereby completing the limiting fixation of the support rod 303. Through the support of the four groups of support rod assemblies 300 with different lengths, the stability of the bracket under uneven terrain can be guaranteed.

Example 2

2 to 8 and 10, a second embodiment of the present invention is shown. Based on the embodiment 1, the embodiment is further improved in that: the limit fixing member 203 includes a limit displacement rod 2031 and a limit clamping rod 2032 arranged inside the limit displacement rod 2031, and a matching slide groove 2033 is provided on the limit clamping rod 2032, wherein the limit displacement rod 2031 is fixedly connected to the adjustment mounting ring 201, and the limit displacement rod 2031 moves up and down inside the fixed through groove 4012, and the limit clamping rod 2032 is symmetrically arranged inside the limit displacement rod 2031, and the limit clamping rod 2032 is symmetrically arranged inside the limit displacement rod 2031, and the limit displacement rod 2032 is symmetrically arranged inside the limit displacement rod 2031. The inside of the rod 2031 moves horizontally, and a spring structure is evenly arranged on the outside of the limit displacement rod 2032. The two ends of the spring structure are respectively fixed on the limit displacement rod 2031 and the limit displacement rod 2032. The matching slide groove 2033 is symmetrically arranged at the two ends of the limit displacement rod 2032, and one side of the matching slide groove 2033 is inclined. A protruding structure is arranged on the side of the limit displacement rod 2032 close to the telescopic rod 401, and the protruding structure passes through the limit displacement rod 2031, and a card strip structure is fixed at equal intervals on one side of the protruding structure, and the card strip structure can be engaged and fixed with the fixed card slot 4013.

The telescopic assembly 400 includes a telescopic rod 401 and a surveying and mapping part 402 connected to the telescopic rod 401. The telescopic rod 401 and the surveying and mapping part 402 are connected in a fixed manner, and the telescopic rod 401 slides inside the main set rod 101 and the installation kit 103; the telescopic rod 401 includes a telescopic rod body 4011 and a fixed through groove 4012 opened on the telescopic rod body 4011, and the interior of the fixed through groove 4012 is connected with a fixed card groove 4013, wherein the fixed through groove 4012 is set through the telescopic rod body 4011, and the fixed card grooves 4013 are symmetrically set on both sides of the fixed through groove 4012, and the fixed card grooves 4013 are evenly arranged at equal intervals; the surveying and mapping part 402 includes a surveying and mapping mounting seat 4021 and a surveying and mapping instrument 4022 connected to the surveying and mapping mounting seat 4021, and the surveying and mapping mounting seat 4021 is fixedly connected to one end of the telescopic rod body 4011.

When the bracket is erected, since the telescopic rod 401 can slide up and down inside the main sleeve rod 101, the height of the telescopic rod 401 can be raised as needed to meet the use requirements and be more convenient to use. After determining the lifting height, the adjustment mounting ring 201 is moved downward. When the support rod assembly 300 is fixed, the telescopic rod 401 can be simultaneously limited and fixed to ensure the normal progress of the surveying and mapping work.

When the adjustment mounting ring 201 moves downward, the limit fixing member 203 slides downward inside the fixed through slot 4012 opened inside the telescopic rod 401. At the same time, since a limit plug rod 1034 is provided on the lower side of the inner part of the sliding limit slot 1033, which is located on the lower side of the limit displacement rod 2031, and a slot is provided at a corresponding position on the lower side of the limit displacement rod 2031, the limit plug rod 1034 can pass through the slot and be connected with the matching slide slot 2033. Since both sides of the upper side of the limit plug rod 1034 are provided with inclined surfaces, the matching The matching surface of the slide groove 2033 and the limiting plug rod 1034 is also inclined, and the inclination angles of the two are the same, so that when the limiting displacement rod 2031 moves downward, the limiting plug rod 1034 is matched with the matching slide groove 2033, and the limiting clamping rod 2032 is pushed to move outward, so that the clamping strip connected to the limiting clamping rod 2032 is engaged with the fixed clamping groove 4013 connected to the inside of the fixed through groove 4012, and the engagement between the two is small, which plays a role in increasing friction, thereby completing the limit fixation of the position of the telescopic rod 401;

When the bracket is folded, first rotate the limiting ring sleeve body 3041 to loosen the restriction on the rotating block 3042, retract the support rod 303, then rotate the adjusting screw 2021 to loosen the restriction on the adjusting block 2023, and then move the adjusting mounting ring 201 upward to close the support sleeve rod 301. At the same time, since the card strip and the fixed card slot 4013 set on the limiting card rod 2032 are relatively small, moving the adjusting mounting ring 201 upward can make the two loosen the engagement under the action of the spring set on one side of the limiting card rod 2032, and finally retract the telescopic rod 401 into the interior of the main sleeve rod 101, completing the folding of the bracket, which can reduce the volume of the bracket for easy carrying and movement.

The remaining structures are the same as those of Example 1.

It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
