[0035] Embodiment 1

[0036] Refer to Figure 1-7 , which is the first embodiment of the present invention, providing a usage method of an engineering survey observation platform to achieve the effects of anti-falling, adjustment, positioning, cleaning and buffering.

[0037] Climb onto the observation support mechanism 1 and connect oneself to the anti-falling mechanism 6 to avoid falling, and place the measuring instrument on the adjustment mechanism 3;

[0038] Start the adjustment mechanism 3 to adjust the height of the measuring instrument. When the measuring instrument rises to the required height, turn off the adjustment mechanism 3. During the adjustment, the automatic positioning mechanism 4 will also be started to quickly fix and install the measuring instrument, making the adjustment and installation synchronous and improving the installation efficiency;

[0040] After the measurement is completed, the adjustment mechanism 3 is activated to lower the measuring instrument. During the lowering process, the cleaning mechanism 5 will be synchronously activated to clean the measuring part of the measuring instrument, and after it is completely lowered, the automatic positioning mechanism 4 will be activated to cancel the positioning and installation of the measuring instrument, so that the measuring instrument can be automatically cleaned and disassembled during the process of being adjusted and lowered when it needs to be removed.

[0041] Embodiment 2

[0042] Refer to Figure 1-6 , which is the second embodiment of the present invention, provides an engineering survey observation platform, including an observation support mechanism 1, a buffer mechanism 2, an adjustment mechanism 3 and a fall prevention mechanism 6. Through the observation support mechanism 1, the buffer mechanism 2, the adjustment mechanism 3 and the fall prevention mechanism 6, single-foot adjustment is realized to free both hands and prevent the user from falling.

[0043] The observation support mechanism 1 includes an observation support platform 101. A support seat 102 is fixedly connected to the bottom of the observation support platform 101. A telescopic ladder 103 is movably connected to the left side of the observation support platform 101 through a pin. A support sleeve 104 is fixedly connected to the top of the observation support platform 101. An installation plate 105 for connecting a measuring instrument is arranged on the top of the support sleeve 104;

[0044] The buffer mechanism 2 includes shock absorbers 201. A plurality of shock absorbers 201 are provided and are evenly distributed in a rectangle. Four buffer plates 202 are arranged on the surface of the support seat 102. The inner side of the shock absorber 201 is fixedly connected to the surface of the support seat 102, and the outer side of the shock absorber 201 is fixedly connected to the inner side of the buffer plate 202;

[0045] Adjusting mechanism 3, which includes a foot pedal airbag 301. The bottom of the foot pedal airbag 301 is fixedly connected to the left side of the top of the observation support platform 101. The bottom of the front of the foot pedal airbag 301 is communicated with a first one-way air valve 302 for preventing gas from escaping. The bottom of the back of the foot pedal airbag 301 is communicated with a second one-way air valve 303 for preventing gas from flowing back. The other end of the second one-way air valve 303 is communicated with the bottom of the back of the support sleeve 104. A piston adjusting rod 304 is slidably connected inside the support sleeve 104. A limit ring 305 is provided at the bottom of the piston adjusting rod 304. The surface of the limit ring 305 is fixedly connected to the bottom surface of the inner wall of the support sleeve 104. The top of the piston adjusting rod 304 is fixedly connected to the bottom of the mounting plate 105. Limit strips 306 are fixedly connected to both the left and right sides of the piston adjusting rod 304. First limit grooves 307 are provided at the top of both the left and right sides of the inner wall of the support sleeve 104. The inner wall of the first limit groove 307 is slidably connected to the surface of the limit strip 306. The bottom of the inner wall of the foot pedal airbag 301 is fixedly connected to a first spring 308. There are four first springs 308 and they are distributed equidistantly in a ring shape. The bottom of the front of the support sleeve 104 is communicated with a three-way exhaust pipe 309. An anti-falling mechanism 6 is fixedly connected to the top of the left side of the support sleeve 104.

[0046] The anti-falling mechanism 6 includes a first telescopic rod 601. The right side of the first telescopic rod 601 is fixedly connected to the top of the left side of the support sleeve 104. A clamp 602 is fixedly connected to the left side of the first telescopic rod 601.

[0047] Further, when the user needs to install the measuring instrument on the observation support platform 101 supported by the support base 102, the user can extend the retractable ladder 103, then climb above the observation support platform 101 through the retractable ladder 103. Next, the user can put the clamp 602 around the waist and tighten it, and use the first telescopic rod 601 to limit the maximum movement space of the clamp 602, so that the user with the clamp 602 cannot fall, improving the safety of the user. At the same time, the first telescopic rod 601 can be telescoped to ensure that the user can move left and right when the clamp 602 is put on, ensuring that the user can approach the mounting plate 105, place the measuring instrument on the mounting plate 105 and debug it. After the measuring instrument is placed on the mounting plate 105, the user can continuously step on the foot-operated airbag 301. Whenever the foot-operated airbag 301 is stepped on and shrinks, the gas inside the foot-operated airbag 301 will enter the support sleeve 104 through the second one-way air valve 303. At the same time, the first spring 308 will be compressed to generate a resilience force. After the user lifts the foot, the resilience force of the first spring 308 is released to drive the foot-operated airbag 301 to expand. At this time, the air pressure inside the foot-operated airbag 301 will be less than the external air pressure, so that the external air enters the inside of the foot-operated airbag 301 through the first one-way air valve 302 for replenishment. In this way, the gas can be continuously injected into the support sleeve 104. The continuously incoming air flow in the support sleeve 104 will continuously generate an upward driving force on the piston adjusting rod 304, causing the movable adjusting rod to move upward. Then the movable adjusting rod will push the mounting plate 105 upward, causing the mounting plate 105 to drive the measuring instrument placed above to move upward. When it moves to the required height, the user can stop stepping on the foot-operated airbag 301. At this time, the height adjustment of the measuring instrument is controlled only by one foot, so that the user can free both hands and concentrate on using the measuring instrument to determine the appropriate height. When the measuring instrument needs to be adjusted downward to reset, the user can discharge the gas in the support sleeve 104 through the three-terminal exhaust pipe 309, so that the gas below the piston adjusting rod 304 is discharged. Then the piston adjusting rod 304 will move downward, and then the piston adjusting rod 304 will drive the mounting plate 105 to move downward synchronously, so that the height of the measuring instrument supported on the mounting plate 105 can be lowered. And during the downward movement, the limit ring 305 can limit the maximum movement distance of the piston adjusting rod 304 downward, preventing the piston adjusting rod 304 from moving downward too far, resulting in the gas not being able to reach the bottom of the piston adjusting rod 304 when entering the support sleeve 104, causing the gas to not be able to smoothly push the piston adjusting rod 304 upward. And during the up and down movement of the piston adjusting rod 304, the sliding fit between the limit strip 306 and the first limit groove 307 can limit the rotation of the piston adjusting rod 304, making the piston more stable when moving upward under the air pressure,After the measuring height of the measuring instrument is adjusted, the user can leave the observation support platform 101 through the retractable ladder 103 and retract the retractable ladder 103 to prevent surrounding construction vehicles from colliding with the retractable ladder 103. During the process of the support base 102 supporting the observation support platform 101, the buffer plate 202 and the damper 201 can buffer the impact force when an external vehicle or foreign object bumps into the support base 102, avoiding excessive impact force that may cause the vibration of the support base 102 to affect the measurement effect of the measuring instrument above the observation support platform 101.

[0048] It should be noted that the crossbars for stepping on the retractable ladder 103 are arranged above each telescopic part of the retractable ladder 103, so that after the retractable ladder 103 is retracted, the crossbars above each telescopic part of the retractable ladder 103 can be retracted and its, ensuring a smaller volume after contraction.

[0049] Embodiment 3

[0050] Refer to Figure 1 、 2 Figures 5 and 6, which are the third embodiment of the present invention. On the basis of Embodiment 2, automatic positioning mechanisms 4 are provided on the front and rear sides of the bottom of the inner wall of the mounting plate 105, and the measuring instrument is automatically installed through the automatic positioning mechanisms 4.

[0051] The automatic positioning mechanism 4 includes a movable groove 401, which is opened on the front and rear sides of the bottom of the inner wall of the mounting plate 105. A positioning plate 402 is slidably connected inside the movable groove 401. A force-receiving inclined plate 403 is fixedly connected to the bottom of the positioning plate 402. A pushing member 404 is movably connected to the inner side of the force-receiving inclined plate 403. The bottom of the inner side of the pushing member 404 is fixedly connected to the top of the front and rear sides of the support sleeve 104. Second springs 405 are fixedly connected to both sides of the front and rear sides of the inner wall of the mounting plate 105. The other ends of the second springs 405 are fixedly connected to the left and right sides of the outer side of the positioning plate 402. Limiting components 406 are opened on the left and right sides of the inner wall of the movable groove 401.

[0052] The limiting component 406 includes a second limiting groove 406a, which is opened on the left and right sides of the inner wall of the movable groove 401. A limiting block 406b is slidably connected inside the second limiting groove 406a. The inner side of the limiting block 406b is connected to the left and right sides of the force-receiving inclined plate 403.

[0053] Further, when the measuring instrument is placed on the mounting plate 105 and the measuring height of the measuring instrument is adjusted by moving upward through the piston adjusting rod 304, the moving groove 401 formed on the mounting plate 105 will gradually separate from the pushing member 404. At this time, since the pushing member 404 is separated from the moving groove 401, the inner side of the force-receiving inclined plate 403 lacks the restriction of the pushing member 404. Then, by utilizing the elastic force of the second spring 405, the positioning plate 402 can be moved inward. Subsequently, the positioning plate 402 will drive the force-receiving inclined plate 403 to move inward, and during the process of the positioning plate 402 moving inward, it will adapt to the width of the measuring instrument and clamp and position the measuring instrument, so that after the distance of the inner wall thickness of the moving groove 401 is adjusted upward on the mounting plate 105, the measuring instrument can be automatically positioned and installed. When the user needs to remove the measuring instrument, the user can lower the height of the mounting plate 105 to the initial height for the user to take. At this time, the pushing members 404 on both sides of the support sleeve 104 will have a relative influence on the mounting plate 105, causing the pushing members 404 to enter the moving groove 401. Then, the inner side of the force-receiving inclined plate 403 will contact the pushing member 404, and when contacting, since the mounting plate 105 drives the force-receiving inclined plate 403 and the positioning plate 402 to move downward, the pushing member 404 will generate an outward pushing force on the force-receiving inclined plate 403 along the inclined surface on the inner side of the force-receiving inclined plate 403. Then, the force-receiving inclined plate 403 will drive the positioning plate 402 to move outward. At this time, the positioning plate 402 will no longer clamp and install the measuring instrument, and then the user can directly remove the measuring instrument.

[0054] Further, during the process of the force-receiving inclined plate 403 moving outward or inward, the force-receiving inclined plate 403 will synchronously drive the limiting block 406b to move, and the limiting block 406b will move along the inner wall of the second limiting groove 406a. By utilizing the sliding fit between the limiting block 406b and the limiting groove, the force-receiving inclined plate 403 can be limited in the up, down, left, and right directions, ensuring that the force-receiving inclined plate 403 and the positioning plate 402 are more stable in the moving process and avoiding the situation of deviation.

[0055] The remaining structure is the same as that of Embodiment 2.

The other ends of the pulling springs 513c are fixedly connected to the left side and the right side of the bottom front surface of the support sleeve 104. An upper inclined block 513d is fixedly connected to the left side of the transmission member 513b. A lower inclined block 513e is slidably connected to the top of the upper inclined block 513d. A second telescopic rod 513f is fixedly connected to the rear side of the bottom of the lower inclined block 513e. The bottom of the second telescopic rod 513f penetrates into the inside of the observation support platform 101. A third spring 513g is sleeved on the surface of the second telescopic rod 513f. A guiding member 513h is fixedly connected to the bottom of the upper inclined block 513d.

[0060] The adaptation assembly 514 includes a screw rod 514a. The surface of the screw rod 514a is threadedly connected to the inside of the support plate 501. A bearing 514b is sleeved on the right side of the surface of the screw rod 514a. The right side of the outer ring of the bearing 514b is fixedly connected to the left side of the rotating rod 502. The screw rod 514a is movably connected to the rotating rod 502 through the bearing 514b.

[0061] The guiding member 513h includes a guiding strip 513h-1. The top of the guiding strip 513h-1 is fixedly connected to the bottom of the upper inclined block 513d. A guiding seat 513h-2 is slidably connected to the front side of the bottom of the guiding strip 513h-1. The bottom of the guiding seat 513h-2 is fixedly connected to the top of the observation support platform 101.

[0062] Further, after the measurement is completed, when the user steps onto the observation support platform 101 and adjusts the mounting plate 105 downward to remove and recycle the measuring instrument, the mounting plate 105 will synchronously drive the support plate 501 and the support rod 511 to move downward. Then, the support plate 501 will drive the rotating rod 502 and the force-receiving fan 506 to move downward, and the support rod 511 will drive the gooseneck tube 510 and the blowing box 507 to move downward. During the process of the mounting plate 105 moving downward for adjustment, it will synchronously drive the piston adjustment rod 304 to discharge the gas in the support sleeve 104 through the three-terminal exhaust pipe 309. The gas during the discharge process will be discharged from the top of the three-terminal exhaust pipe 309. Then, the discharged air flow will enter the hose 512 and enter the gooseneck tube 510 guided by the hose 512, then enter the blowing box 507 through the gooseneck tube 510, and then be discharged through the blowing slots 509 and blowing holes 508 opened on the blowing box 507. The air flow discharged through the blowing holes 508 will be concentrated and blown towards the force-receiving fan 506, causing the force-receiving fan 506 to rotate. Then, the force-receiving fan 506 drives the rotating rod 502 to rotate, and then the rotating rod 502 drives the transmission rod 503 to rotate, causing the transmission rod 503 to drive the scraping strip 505 and the cleaning cotton to continuously rotate. Subsequently, the scraping strip 505 and the cleaning cotton will continuously contact the measuring part of the measuring instrument during the downward movement of the measuring instrument, so as to wipe and scrape the measuring part of the measuring instrument for cleaning. The wind blown out through the blowing slots 509 can not only blow the measuring part of the measuring instrument to blow out some easily cleaned dust, but also blow away the foreign objects cleaned, so that the measuring instrument can be cleaned synchronously during the removal process. Moreover, the gooseneck tube 510 can arbitrarily adjust the angle and position of the blowing box 507, so as to ensure that the blowing box 507 blows the wind to the force-receiving fan 506 and the measuring part of the measuring instrument at a position that does not affect the measurement of the measuring instrument.

[0063] Further, when the user needs to discharge the gas inside the support sleeve 104, the user can move the foot position to above the lower inclined block 513e, and then step on the lower inclined block 513e to move the lower inclined block 513e downward. Then, by using the sliding connection between the bottom inclined surface of the lower inclined block 513e and the top inclined surface of the upper inclined block 513d, when the lower inclined block 513e moves downward, it will push the upper inclined block 513d to move forward. Then, the upper inclined block 513d will drive the transmission member 513b to move outward, so that the transmission member 513b drives the seal 513a in the three-way exhaust pipe 309 to move forward, enabling the top end of the three-way exhaust pipe 309 to communicate with the inside of the support sleeve 104. At this time, the gas inside the support sleeve 104 can be discharged through the top end of the three-way exhaust pipe 309. At the same time, the tension spring 513c is pulled by the transmission member 513b and the third spring 513g generates a resilience force when being compressed. After the exhaust is completed, the user's foot releases the lower inclined block 513e. Then, by using the elastic force of the third spring 513g, the mechanism upper inclined block 513d can be pushed to reset, and the tension of the tension spring 513c is also released to pull the transmission member 513b to reset, so that the transmission member 513b drives the upper inclined block 513d and the seal 513a to reset, thus re-sealing the rear end of the three-section exhaust pipe. During the up and down movement of the upper inclined block 513d, the second telescopic rod 513f can limit the movement track of the lower inclined block 513e in the front, rear, left, and right directions to ensure the movement of the lower inclined block 513e is more stable.

[0064] Further, in the case of corresponding to different measuring instruments, the distance between the measuring part of the measuring instrument and the transmission rod 503 is also different. At this time, the user can rotate the screw 514a. By using the threaded connection between the screw 514a and the support plate 501, the screw 514a rotates and moves to the left. Then, the screw 514a will drive the rotating rod 502, the transmission rod 503, the cleaning cotton strip 504, the scraping strip 505, and the stress member to move left and right to adapt to the measuring parts of different measuring instruments. At the same time, by using the screw 514a to be movably connected to the rotating rod 502 through the bearing 514b, the rotation of the rotating rod 502 is prevented from driving the screw 514a to rotate.

[0065] During the process of the lower inclined block 513e moving under force, the lower inclined block 513e can be supported by the guide seat 513h-2. At the same time, by using the sliding connection between the guide strip 513h-1 and the guide seat 513h-2, the upper inclined block 513d can be limited in the left, right, up, and down directions to ensure that the upper inclined block 513d moves stably during the movement and avoid deviation during the movement.

[0066] The remaining structures are the same as those in Embodiments 2 and 3.

[0067] The specific usage method of the present invention includes the following steps:

[0068] When the user needs to install the measuring instrument on the observation support platform 101 supported by the support base 102, the user can extend the telescopic ladder 103, and then the user climbs above the observation support platform 101 through the telescopic ladder 103. Then, the user can put the clamp 602 on the user's waist and tighten it, and the first telescopic rod 601 can limit the maximum movement space of the clamp 602, so that the user wearing the clamp 602 will not fall, improving the safety of the user. At the same time, the first telescopic rod 601 can be telescoped to ensure that the user can move left and right when wearing the clamp 602, ensuring that the user can approach the mounting plate 105, place the measuring instrument on the mounting plate 105 and debug it.

[0069] After the measuring instrument is placed on the mounting plate 105, the user can continuously step on the foot-operated airbag 301. Whenever the foot-operated airbag 301 is stepped on and shrinks, the gas inside the foot-operated airbag 301 will enter the support sleeve 104 through the second one-way air valve 303. At the same time, the first spring 308 will be compressed to generate a resilience force. After the user lifts the foot, the resilience force of the first spring 308 is released to drive the foot-operated airbag 301 to expand. At this time, the air pressure inside the foot-operated airbag 301 will be less than the external air pressure, so that the external air enters the inside of the foot-operated airbag 301 through the first one-way air valve 302 for replenishment. By repeating this process, gas can be continuously injected into the support sleeve 104. The continuous airflow entering the support sleeve 104 will continuously generate an upward driving force on the piston adjusting rod 304, causing the movable adjusting rod to move upward. Then the movable adjusting rod will push the mounting plate 105 upward, causing the mounting plate 105 to drive the measuring instrument placed above to move upward. When it moves to the required height, the user can stop stepping on the foot-operated airbag 301. At this time, the height adjustment of the measuring instrument is controlled only by one foot, so that the user can free both hands and concentrate on using the measuring instrument to determine the appropriate height. When it is necessary to adjust the measuring instrument downward for resetting, the user can discharge the gas in the support sleeve 104 through the three-terminal exhaust pipe 309, so that the gas below the piston adjusting rod 304 is discharged. Then the piston adjusting rod 304 will move downward, and then the piston adjusting rod 304 will drive the mounting plate 105 to move downward synchronously, so that the height of the measuring instrument supported on the mounting plate 105 can be lowered. And during the downward movement, the limit ring 305 can limit the maximum movement distance of the piston adjusting rod 304 downward, avoiding that the distance of the piston adjusting rod 304 moving downward is too large, resulting in the gas not being able to reach the bottom of the piston adjusting rod 304 when entering the support sleeve 104, which causes the gas to not be able to smoothly push the piston adjusting rod 304 upward. And during the up and down movement of the piston adjusting rod 304, the sliding fit between the limit strip 306 and the first limit groove 307 can limit the rotation of the piston adjusting rod 304, making the piston more stable when moving upward under the air pressure.

[0070] When the measuring instrument is placed on the mounting plate 105 and the measuring height of the measuring instrument is adjusted by moving upward through the piston adjusting rod 304, the moving groove 401 formed on the mounting plate 105 will gradually separate from the pushing member 404. At this time, since the pushing member 404 is separated from the moving groove 401, the inner side of the force-bearing inclined plate 403 lacks the restriction of the pushing member 404. Then, by using the elastic force of the second spring 405, the positioning plate 402 can be moved inward. Then, the positioning plate 402 will drive the force-bearing inclined plate 403 to move inward, and during the process of the positioning plate 402 moving inward, it can adapt to the width of the measuring instrument and clamp and position the measuring instrument, so that after the distance between the inner walls of the moving groove 401 is adjusted upward on the mounting plate 105, the measuring instrument can be automatically positioned and installed. When the user needs to remove the measuring instrument, the user can lower the height of the mounting plate 105 to the initial height for the user to take. At this time, the pushing members 404 on both sides of the support sleeve 104 will have a relative influence on the mounting plate 105, so that the pushing members 404 enter the moving groove 401. Then, the inner side of the force-bearing inclined plate 403 will contact the pushing member 404. When contacting, since the mounting plate 105 drives the force-bearing inclined plate 403 and the positioning plate 402 to move downward, the pushing member 404 generates an outward pushing force on the force-bearing inclined plate 403 along the inclined surface of the inner side of the force-bearing inclined plate 403. Then, the force-bearing inclined plate 403 will drive the positioning plate 402 to move outward. At this time, the positioning plate 402 will no longer clamp and install the measuring instrument. Then, the user can directly remove the measuring instrument. And through the force-bearing inclined plate 403 with a proper inclination, it can ensure that the moving distance when the force-bearing inclined plate 403 and the pushing member 404 move is sufficient to fix the measuring instrument.

[0071] During the process of the force-bearing inclined plate 403 moving outward or inward, the force-bearing inclined plate 403 will synchronously drive the limit block 406b to move, and the limit block 406b will move along the inner wall of the second limit groove 406a. By using the sliding fit between the limit block 406b and the limit groove, the force-bearing inclined plate 403 can be limited in the up, down, left, and right directions, ensuring that the direction is more stable during the movement of the force-bearing inclined plate 403 and the positioning plate 402, and avoiding the situation of deviation.

[0072] After the measuring height of the measuring instrument is adjusted, the user can leave the observation support platform 101 through the retractable ladder 103 and retract the retractable ladder 103 to prevent surrounding construction vehicles from colliding with the retractable ladder 103. During the process of the support base 102 supporting the observation support platform 101, through the buffer plate 202 and the damper 201, the impact force when an external vehicle or foreign object collides with the support base 102 can be buffered, avoiding excessive impact force that may cause the vibration of the support base 102 to affect the measuring effect of the measuring instrument above the observation support platform 101.

[0073] After the measurement is completed, when the user steps onto the observation support platform 101 and adjusts the mounting plate 105 downward to remove and recycle the measuring instrument, the mounting plate 105 will synchronously drive the support plate 501 and the support rod 511 to move downward. Then, the support plate 501 will drive the rotating rod 502 and the force-receiving fan 506 to move downward, and the support rod 511 will drive the gooseneck tube 510 and the blowing box 507 to move downward. During the process of the mounting plate 105 moving downward for adjustment, it will synchronously drive the piston adjustment rod 304 to discharge the gas in the support sleeve 104 through the three-terminal exhaust pipe 309. The gas during the discharge process will be discharged from the top of the three-terminal exhaust pipe 309. Then, the discharged air flow will enter the hose 512 and enter the gooseneck tube 510 guided by the hose 512, then enter the blowing box 507 through the gooseneck tube 510, and then be discharged through the blowing slots 509 and blowing holes 508 opened on the blowing box 507. The air flow discharged through the blowing holes 508 will be concentrated and blown towards the force-receiving fan 506, causing the force-receiving fan 506 to rotate. Then, the force-receiving fan 506 drives the rotating rod 502 to rotate, and then the rotating rod 502 drives the transmission rod 503 to rotate, causing the transmission rod 503 to drive the scraping strip 505 and the cleaning cotton to continuously rotate. Subsequently, the scraping strip 505 and the cleaning cotton will continuously contact the measuring part of the measuring instrument during the downward movement of the measuring instrument, so as to wipe and scrape the measuring part of the measuring instrument for cleaning. The wind blown out through the blowing slots 509 can not only blow the measuring part of the measuring instrument to blow out some easily cleaned dust, but also blow away the foreign objects cleaned, so that the measuring instrument can be cleaned synchronously during the removal process. Moreover, the gooseneck tube 510 can arbitrarily adjust the angle and position of the blowing box 507, so as to ensure that the blowing box 507 blows the wind to the force-receiving fan 506 and the measuring part of the measuring instrument at a position that does not affect the measurement of the measuring instrument.

[0074] When the user needs to discharge the gas in the support sleeve 104, the user can move to above the lower inclined block 513e by adjusting the position of the user's foot, and then step on the lower inclined block 513e to make the lower inclined block 513e move downward. Then, by utilizing the sliding connection between the bottom inclined surface of the lower inclined block 513e and the top inclined surface of the upper inclined block 513d, when the lower inclined block 513e moves downward, it will push the upper inclined block 513d to move forward. Then, the upper inclined block 513d will drive the transmission member 513b to move outward, causing the transmission member 513b to drive the seal 513a in the three-end exhaust pipe 309 to move forward, so that the top end of the three-end exhaust pipe 309 can communicate with the inside of the support sleeve 104. At this time, the gas in the support sleeve 104 can be discharged through the top end of the three-end exhaust pipe 309. At the same time, the tension spring 513c is pulled by the transmission member 513b and the third spring 513g is compressed to generate a restoring force. After the exhaust is completed, the user's foot releases the lower inclined block 513e. Then, the elastic force of the third spring 513g can push the mechanism upper inclined block 513d to reset, and the tension of the tension spring 513c is also released to pull the transmission member 513b to reset, causing the transmission member 513b to drive the upper inclined block 513d and the seal 513a to reset, thereby re-sealing the rear end of the three-section exhaust pipe. During the up and down movement of the upper inclined block 513d, the second telescopic rod 513f can limit the movement trajectory of the lower inclined block 513e in the front, back, left, and right directions to ensure the movement of the lower inclined block 513e is more stable.

[0075] During the process of the lower inclined block 513e moving under force, the guide seat 513h-2 can assist in supporting the lower inclined block 513e. At the same time, by utilizing the sliding connection between the guide strip 513h-1 and the guide seat 513h-2, the upper inclined block 513d can be limited in the left, right, up, and down directions to ensure that the upper inclined block 513d moves stably during the movement process and avoid deviation during the movement.

[0076] In the case of corresponding to different measuring instruments, the distance between the measuring part of the measuring instrument and the transmission rod 503 is also different. At this time, the user can rotate the screw 514a. By utilizing the threaded connection between the screw 514a and the support plate 501, the screw 514a rotates and moves to the left. Then, the screw 514a will drive the rotating rod 502, the transmission rod 503, the cleaning cotton strip 504, the scraping strip 505, and the force-receiving member to move left and right to adapt to the measuring part of different measuring instruments. At the same time, the screw 514a is movably connected to the rotating rod 502 through the bearing 514b, thereby preventing the screw 514a from rotating when the rotating rod 502 rotates.

[0077] In summary, the measuring instrument is supported by the observation support mechanism 1, the height of the measuring instrument is adjusted by the adjustment mechanism 3, the stability of the support can be ensured by the buffer mechanism 2, the cleaning mechanism 5 can clean the measurement location during the removal of the measuring instrument, the automatic positioning mechanism 4 can automatically position and disassemble the measuring instrument, and the anti-falling mechanism 6 can prevent the user from falling from the observation support mechanism 1.

[0078] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope of the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
