Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0026] See also Figure 1-3 The utility model provides a new technical solution: an auxiliary surveying and mapping device for construction engineering, comprising a fixed plate 1, on which a surveying and mapping instrument 17 is fixedly mounted, and on which two portable adjustment support devices are arranged, the two portable adjustment support devices are arranged in mirror symmetry, and the portable adjustment support devices are used to support and adjust the position of the surveying and mapping instrument 17;
[0027] The portable adjustable support device comprises a rotating shaft 4, a rotating plate 5, two worm gears 6, two hexagonal sliding shafts 8, two worms 9, two springs 10 and an adjustable rotating disk 15;
[0028] The portable adjustable support device also includes a side fixing frame 2, which is fixedly connected to one side of the upper surface of the fixing plate 1, and a fixing seat 3 is fixedly connected to the outer surface of the side fixing frame 2;
[0029] The rotating shaft 4 is rotatably connected in the fixed seat 3, and both ends of the rotating shaft 4 are rotatably connected and penetrate through the outer surfaces of both sides of the rotating plate 5, and two worm gears 6 are fixedly sleeved on both ends of the rotating shaft 4 respectively;
[0030] Two hexagonal sliding shafts 8 are arranged on both sides of the side fixing frame 2 . The outer surfaces of the two hexagonal sliding shafts 8 are rotatably connected to two hexagonal shaft fixing plates 7 . The two hexagonal shaft fixing plates 7 are fixedly connected to the two sides of the side fixing frame 2 .
[0031] Furthermore, the two worms 9 are respectively slidably sleeved on the outer surfaces of the corresponding hexagonal sliding shafts 8 , and the two worms 9 are respectively meshed and connected with the corresponding worm wheels 6 .
[0032] Furthermore, two springs 10 are respectively sleeved on the outer surfaces of the corresponding hexagonal sliding shafts 8 , and the two springs 10 are respectively located between the corresponding upper hexagonal shaft fixing plate 7 and the worm 9 .
[0033] Furthermore, the upper ends of the hexagonal sliding shafts 8 are rotated to penetrate the outer surface of the upper hexagonal shaft fixing plate 7 and are fixedly sleeved with a small sprocket 11, and the center position of the lower surface of the fixing plate 1 is rotatably connected with a center column 12.
[0034] Furthermore, a large sprocket 13 is fixedly sleeved on the outer surface of the central column 12 , a chain 14 is transmission-connected between the large sprocket 13 and a plurality of small sprockets 11 , and an adjusting dial 15 is fixedly sleeved on the lower end of the central column 12 .
[0035] Furthermore, the lower surfaces of the two side fixing frames 2 are fixedly connected with support feet 16, and the thread directions of the multiple worm gears 9 in the two portable adjustable support devices are arranged in opposite directions, so that the rotation directions of the multiple worm wheels 6 can be synchronized in opposite directions.
[0036] Furthermore, when in use, the rotating plate 5 is manually rotated outward, and the rotating plate 5 will drive the worm wheel 6 to rotate upward through the rotating shaft 4 thereon.

[0037] Furthermore, the self-locking property of the meshing of the worm wheel 6 and the worm 9 in the two portable adjustable support devices can also ensure that the surveying instrument 17 has better stability when adjusting the height during surveying and mapping operations, thereby avoiding the problem of the surveying instrument shaking due to structural instability when adjusting the height of the traditional auxiliary support device, which affects the measurement accuracy, thereby ensuring accuracy and safety during the surveying and mapping process.
[0038] Working principle: when in use, the rotating plate 5 is manually rotated outward, and the rotating plate 5 will drive the worm wheel 6 to rotate upward through the rotating shaft 4 thereon. The upward rotating worm wheel 6 will apply an upward force to the worm 9, so that the worm 9 can move in the axial direction of the hexagonal sliding shaft 8. At the same time, the worm 9 will drive the spring 10 to compress and deform until the adjusting dial 15 is rotated to a position slightly lower than the fixed plate 1, and then placed at the required position. By rotating the adjusting dial 15, the adjusting dial 15 can drive the chain 14 on the large sprocket 13 to rotate through the center column 12, so that the rotating chain 14 can drive some small sprockets 11 to rotate together, and when the small sprocket 11 rotates, it can drive the hexagonal sliding shaft 8 to rotate, and when the hexagonal sliding shaft 8 rotates, it can drive the worm wheel 6 to rotate through the worm 9, and when the worm wheel 6 rotates, it can drive the rotating plate 5 to rotate downward through the rotating shaft 4, thereby driving the surveying instrument 17 to be adjusted to a suitable height position.
