DETAILED DESCRIPTION

[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1, as Figure 1-Figure 5As shown, the utility model provides a surveying and mapping benchmark, including: a first benchmark 1 and a second benchmark 2, the bottom of the first benchmark 1 is fixedly connected with a round block 5, the bottom of the round block 5 is symmetrically provided with a limiting groove 8, the inner top of the two limiting grooves 8 are provided with a first arc groove 9, the top of the second benchmark 2 is provided with a circular groove 6, the inner wall of the circular groove 6 is fixedly connected with a limiting block 7 near the center position, the inner bottom of the two limiting blocks 7 are fixedly connected with a first telescopic rod 12, the outer surfaces of the two first telescopic rods 12 are sleeved with a first spring 13, the tops of the two first telescopic rods 12 are fixedly connected with a first arc block 11, the outer surface of the second benchmark 2 is sleeved with a protective cover 3, the bottom of the second benchmark 2 is fixedly connected with a cone head 4, the inner surface of the circular groove 6 matches the outer surface of the round block 5, the two limiting blocks 7 are respectively matched with the two limiting grooves 8, and the two first arc blocks 11 are respectively matched with the two first arc grooves 9.

[0025] The effect achieved by the entire embodiment 1 is that when the first marker 1 and the second marker 2 need to be assembled, after aligning the two limit grooves 8 with the two limit blocks 7, the first marker 1 is pressed downward so that the round block 5 is inserted into the round groove 6. Under the action of pressure, the first arc block 11 is driven to move into the limit block 7, and the first spring 13 and the first telescopic rod 12 are driven to be compressed. Then the first marker 1 is rotated so that the limit block 7 rotates in the limit groove 8. When the outer side of the limit block 7 is fitted with the limit groove 8, the first arc groove 9 is aligned with the first arc block 11, so that under the action of the first spring 13, the first arc block 11 is pushed outward and engaged with the first arc groove 9, and in the first telescopic rod 12, the first arc block 11 is pushed outward and engaged with the first arc groove 9. Under the action of the retracted rod 12, the linearity of the movement of the first arc block 11 is guaranteed, the circular block 5 is limited and fixed, and the rapid assembly of the first marker 1 and the second marker 2 is completed. When disassembly is required, it is only necessary to rotate the first marker 1 in the opposite direction with force, so that the first arc groove 9 will exert pressure on the outside of the first arc block 11, so that it moves into the limit block 7, and then under the action of the first marker 1, the limit block 7 will be driven to rotate in the limit groove 8 and fit with the other side of the limit groove 8. Then, the first marker 1 can be quickly removed from the second marker 2. The top of the first marker 1 is also provided with a circular groove 6 and a limit block 7, so that the staff can add the number of first markers 1 according to height requirements, which is highly practical.

[0026] Example 2, as Figure 1-Figure 5As shown, a slide groove 17 is provided on the inner surface of the protective cover 3, and a slider 10 is fixedly connected to the outer surface of the second benchmark 2 near the bottom. The outer surface of the slider 10 is slidably connected to the inner surface of the slide groove 17. A mounting groove 18 is provided on the outer surface of the second benchmark 2 near the bottom. The inner surface of the mounting groove 18 is fixedly connected to the second telescopic rod 14. The outer surface of the second telescopic rod 14 is sleeved with a second spring 19. The top of the second telescopic rod 14 is fixedly connected to a second arc block 16. Two second arc grooves 15 are provided on the inner surface of the protective cover 3 away from the slide groove 17. The two second arc grooves 15 are respectively matched with the second arc block 16. The length of the protective cover 3 is greater than the length of the cone head 4.

[0027] The effect achieved by the entire embodiment 2 is that when the cone head 4 is not needed, the protective sleeve 3 can be pushed downward with force, so that the second arc groove 15 applies pressure on the outside of the second arc block 16, so that the second arc block 16 moves to the installation groove 18, and drives the second spring 19 and the second telescopic rod 14 to be compressed, so that after the protective sleeve 3 loses its limit, it is slightly pushed downward. At the same time, under the action of the slider 10 and the slide groove 17, the stability of the protective sleeve 3 during movement is guaranteed. Therefore, when the protective sleeve 3 moves downward, the installation groove 18 will be flush with the other second arc groove 15, so that under the action of the second spring 19 and the second telescopic rod 14, the second arc block 16 will be driven to move to the second arc groove 15 and engage, completing the limitation of the protective sleeve 3. Therefore, the cone head 4 can be protected by the protective sleeve 3, reducing the occurrence of accidents.

[0028] Working principle: When the first marker 1 and the second marker 2 need to be assembled, align the two limit grooves 8 with the two limit blocks 7, press the first marker 1 downward, so that the round block 5 is inserted into the round groove 6, and the first arc block 11 is driven to move into the limit block 7 under the action of pressure, and the first spring 13 and the first telescopic rod 12 are driven to be compressed, and then the first marker 1 is rotated to make the limit block 7 rotate in the limit groove 8. When the outer side of the limit block 7 is in contact with the limit groove 8, the first arc groove 9 is pressed against the limit groove 8. The first arc block 11 is aligned with the first arc block 11, so that under the action of the first spring 13, the first arc block 11 is pushed outward and engaged with the first arc groove 9, and under the action of the first telescopic rod 12, the linearity of the movement of the first arc block 11 is guaranteed, the round block 5 is limited and fixed, and the rapid assembly of the first marker 1 and the second marker 2 is completed. When disassembly is required, it is only necessary to force the first marker 1 to rotate in the opposite direction, so that the first arc groove 9 will apply pressure to the outside of the first arc block 11, so that it moves to the limit. When the first lever 1 is in the working state, the second spring 19 and the second telescopic rod 14 are pressed together, so that the second arc block 16 is pressed into the second arc block 16 and the second arc block 16 is pressed into the second arc block 16. When the first lever 1 is in the working state, the second arc block 16 is pressed into the second arc block 16 and the second telescopic rod 14 is pressed together. When the first lever 1 is in the working state, the second arc block 16 is pressed into the second arc block 16 and the second arc block 16 is pressed into the second arc block 16. When the first lever 1 is in the working state, the second arc block 16 is pressed into the second arc block 16 and the second telescopic rod 14 is pressed together. When the first lever 1 is in the working state, the second arc block 16 is pressed into the second arc block 16 and the second
