[0025] The utility model is further introduced below in conjunction with the accompanying drawings and specific embodiments:

[0026] refer to Figures 1 to 5 A high-stability surveying instrument bracket includes: a ring member 14, a telescopic support frame, a core seat 15, a second plug member 17, and a threaded sleeve 18.

[0027] The top of the telescopic support frame is rotatably connected to the ring member 14 through a pin, and three groups of telescopic support frames are provided, and the three groups of telescopic support frames are distributed in a ring array, such as Figure 1 , a schematic diagram of three sets of telescopic support frames in working state, which can stably support the annular member 14.

[0028] The top of the core seat 15 is provided with a surveying instrument mounting portion, which cooperates with the bottom of the surveying instrument (the specific structural design can be determined according to the bottom of the surveying instrument). The bottom of the core seat 15 has an insertion portion, which is located on the inner side of the ring 14.

[0029] The bottom end of the insertion part is fixedly connected to the first threaded rod 16, the bottom end of the second soil insert 17 is a pointed part to facilitate its insertion into the soil, the top end of the second soil insert 17 is a threaded section, the top end of the threaded sleeve 18 is threadedly connected to the bottom end of the first threaded rod 16, and the bottom end of the threaded sleeve 18 is threadedly connected to the top end of the second soil insert 17.

[0030] like Figure 1 As shown in the figure, the bottom end of the second plug 17 is first inserted into the predetermined surveying position, then the telescopic support frame is installed, and the insertion portion of the bottom end of the core seat 15 is inserted into the inner side of the ring member 14, and finally the threaded sleeve 18 is installed and adjusted so that the core seat 15 presses the top of the ring member 14.

[0031] The telescopic support frame comprises: a hollow cylinder 1, a sliding member 2, and a connecting rod 9.

[0032] Among them, the inner cavity cross-section of the hollow cylinder 1 gradually decreases from top to bottom, the sliding member 2 is slidably connected to the bottom of the hollow cylinder 1, and the downwardly extending part of the bottom of the hollow cylinder 1 is a straight section to ensure that the sliding member 2 and the hollow cylinder 1 can slide smoothly. The outer side of the hollow cylinder 1 is threadedly connected with an adjusting screw 19, and one end of the adjusting screw 19 is against the outer side of the sliding member 2. The user can operate the adjusting screw 19 to fix or loosen the sliding member 2 and the hollow cylinder 1. A core tube hole 7 is opened at the top of the sliding member 2, and a connecting rod 9 is located in the inner cavity of the hollow cylinder 1. A rectangular plate 8 is fixedly connected to the top of the connecting rod 9. The cross-section of the rectangular plate 8 corresponds to the inner cavity cross-section of the middle section of the hollow cylinder 1. The bottom end of the connecting rod 9 is located inside the core tube hole 7 and is fixedly connected to an upper plate body 10. The bottom end of the upper plate body 10 is fixedly connected to a spring 11, and the bottom end of the spring 11 is fixedly connected to the inner bottom of the core tube hole 7.

[0033] The principle of stable telescopic support frame: 1. When the required length of the telescopic support frame is not large, the sliding member 2 is slid out of a part of the hollow cylinder 1, and most of the sliding member 2 is located inside the hollow cylinder 1. At this time, the stability of sliding is guaranteed by its own structure; 2. When the length to be used is larger, after the sliding member 2 slides out half of the hollow cylinder 1, the rectangular plate 8 is stuck in the inner cavity of the hollow cylinder. At this time, the rectangular plate 8 will not continue to slide downward, and the sliding member 2 will continue to slide out of the hollow cylinder 1. The connecting rod 9 and the upper plate body 10 at the bottom will slide with the core tube hole 7, and the spring 11 will be synchronously stretched. At this time, the rectangular plate 8 and the hollow cylinder 1 are stably stuck. At this time, there are two sliding relationships between the sliding member 2 (1 is the sliding member 2 and the upper plate body, connecting rod; 2 is the sliding member 2 from the hollow cylinder 1), and the structure is more stable.

[0034] In one embodiment, a sliding hole 3 is provided at the bottom end of the sliding member 2, and a first plug 5 is slidably connected to the inner side of the sliding hole 3, and the bottom end of the first plug 5 is a pointed part. A side hole 4 connected to the sliding hole 3 is provided on the side of the sliding member 2, and a push plate 6 is fixedly connected to the side of the first plug 5, and a part of the push plate 6 is located in the sliding hole 3, and the main body of the sliding hole 3 is located on the outside of the sliding member 2.

[0035] Install the telescopic support frame as follows: Figure 1 After the state shown is placed, the user steps on the push plate 6 with his foot to slide the sliding member 2 downward and insert it into the soil, thereby ensuring the stability of the bottom end of the telescopic support frame.

[0036] In one embodiment, the bottom end of the spring 11 is fixedly connected to a lower plate body 12, which is located at the inner bottom of the core barrel hole 7. A long screw is fixedly connected to the side of the sliding member 2 and located at the inner bottom of the core barrel hole 7, and one end of the long screw is against the side of the lower plate body 12.

[0037] The design of this structure aims to facilitate installation by fixing the lower plate body 12 to the bottom end of the spring 11. This process can be completed externally. After completion, the lower plate body 12 is inserted into the inner bottom of the core barrel hole 7, and then the long screws are tightened to fix the lower plate body 12 to the core barrel hole 7, thereby achieving the purpose of fixing the spring 11.

[0038] A connector 13 is fixedly connected to the top of the hollow cylinder 1. The top of the connector 13 is provided with an ear plate, and the ear plate is rotatably connected to the annular member 14 via a pin shaft.

[0039] An anti-slip portion is provided on the outer side of the threaded sleeve 18 to facilitate the rotation of the threaded sleeve 18 .

[0040] An injection-molded tip is provided at the end of the adjusting screw 19 to facilitate the rotation of the adjusting screw 19 .

[0041] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementations, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
