[0019] The present application has the following advantages:

[0020] (1) When the present application is used, the user carries the outer sleeve to the position to be measured, supports the outer sleeve by contacting the supporting legs with the ground, and when the height of the inner sleeve needs to be adjusted, the user holds the outer sleeve with both hands, places the heel on the supporting plate and the toe on the rubber expansion block, then treads on the rubber expansion block, so that the pedal rotates, the side of the pedal treaded by the foot descends, the other side rises, the rising side lifts the sliding frame, so that the inner sleeve rises, the height of the inner sleeve is adjusted, when the sliding frame rises, the piston ring one also rises, the piston ring one extrudes the hydraulic oil one in the fixed sleeve one, the extruded hydraulic oil one pushes the spring ball rod to move, so that the spring ball rod is separated from the conical ring, the spring ball rod accumulates the elastic force, since the shape of the conical ring is conical, after the spring ball rod is separated from the conical ring, a gap is formed between the two, the hydraulic oil one enters the oil pipe through the gap and mixes with the hydraulic oil three in the oil pipe, then enters the bottom of the piston ring two through the oil pipe and mixes with the hydraulic oil two, so that the piston ring two is lifted and contacts the bottom of the pedal, when the height adjustment of the inner sleeve is completed, the pedal is released, at this time, the force extruding the hydraulic oil one disappears, the extrusion force of the spring ball rod also disappears, the elastic force of the spring ball rod is released, so that the spring ball rod contacts the conical surface of the conical ring again, thereby blocking the conical ring, at this time, the top of the piston ring two contacts the bottom of the pedal, and the bottom of the piston ring two is supported by the hydraulic oil two, so that the pedal is prevented from supporting and the inner sleeve is prevented from descending, when the inner sleeve needs to descend, the push rod is manually pushed towards the spring ball rod, so that the push rod pushes the spring ball rod away from the conical ring, the fixed sleeve two is connected with the fixed sleeve one, the inner sleeve is affected by the weight and descends, the sliding frame extrudes the pedal, the pedal extrudes the piston ring two, so that the hydraulic oil two in the fixed sleeve two enters the fixed sleeve one through the oil pipe, the descent of the inner sleeve is completed, thereby realizing the rapid adjustment of the height of the inner sleeve, reducing the cumbersome operation steps and making the operation more convenient.

[0021] (2) When the sliding frame rises, the sliding plate also rises, the sliding plate extrudes the gas in the connecting frame, the extruded gas enters the gas conveying hose and then enters the rubber expansion block, so that the rubber expansion block expands and better fits the sole of the user, at the same time, when the sliding frame rises, the rotating frame also rises, the rotating frame rotates and tilts, the spring plate is pushed down, the rubber pressing plate is also pushed down and contacts the toe of the user, the rubber expansion block expands and cooperates with the rubber pressing plate, so that the stability between the vamp and the rubber expansion block is increased, effectively preventing the rubber expansion block from sliding when it is treaded and affecting the stability of the user controlling the height of the inner sleeve.

[0022] (3) The spring plate descends, drives the connecting rod to descend, and the connecting rod drives the connecting rod to rotate. The connecting rod pushes the extrusion plate I to move towards the pedal direction. When the extrusion plate I covers the air inlet hole, the extrusion plate I extrudes the gas in the fixed frame I. The gas enters the inclined block through the air inlet pipe. At this time, the extruded gas is blocked by the spring blocking plate, so the gas generates high pressure. During the movement of the extrusion plate I, the connecting rod II is also moved until the connecting rod II contacts the spring blocking plate, drives the spring blocking plate to rotate, accumulates the elastic force of the spring blocking plate, and makes the spring blocking plate and the inclined block leak the gap. Since the pedal is inclined when it is stepped on, the rubber expansion block is also inclined, and the shape of the inclined block is also inclined, as shown in Figure Eight When the spring blocking plate rotates, the high-pressure gas is sprayed from the gap to the surface of the rubber expansion block, which cleans the soil on the surface of the rubber expansion block. This effectively prevents the surveying and mapping environment from having a lot of soil, which adheres to the shoes and then falls on the rubber expansion block, causing the soil on the rubber expansion block to pile up more and more, which may cause slipping when stepping on it, thereby reducing the impact of slipping on controlling the height of the inner sleeve.

[0023] (4) The extrusion plate I also drives the connecting rod III to move when it moves. The connecting rod III pushes the extrusion plate II to move. The extrusion plate II extrudes the gas in the fixed frame II. The extruded gas enters the air jet pipe and is sprayed to the user's feet through the air jet pipe. During the rotation of the pedal, the air jet pipe frequently sprays light gas to the user's feet, which helps to relieve the user's feet and reduce the fatigue caused by stepping on the pedal.

[0054] Secondly, when the spring plate 46 descends, the connecting rod one 53 will descend, the connecting rod one 53 will rotate the connecting rod 521, the connecting rod 521 will push the extrusion plate one 52 to move towards the direction of the pedal 14, when the extrusion plate one 52 covers the air inlet hole 511, the extrusion plate one 52 will extrude the gas in the fixed frame one 51, the gas will enter the inclined block 55 through the air inlet pipe 54, at this time, the extruded gas will be blocked by the spring blocking plate 551, so the gas will produce high pressure, during the movement of the extrusion plate one 52, the connecting rod two 56 will also move, until the connecting rod two 56 contacts the spring blocking plate 551, pushes the spring blocking plate 551 to rotate, so that the spring blocking plate 551 accumulates the elastic force, and the spring blocking plate 551 and the inclined block 55 leak between the gap, because the pedal 14 will be inclined when stepped on, the rubber expansion block 141 will also be inclined, and the shape of the inclined block 55 is also inclined, as shown in Figure Eight When the spring blocking plate 551 rotates, the high-pressure gas will be sprayed from the gap to the surface of the rubber expansion block 141, cleaning the soil on the surface of the rubber expansion block 141, effectively preventing the surveying environment from having more soil, the soil adhering to the shoes, and then falling from the shoes to the rubber expansion block 141, causing the soil on the rubber expansion block 141 to pile up more and more, which may cause slipping when stepping on subsequently, thereby reducing the influence of slipping on controlling the height of the inner sleeve 11;

[0055] When the inner sleeve 11 is lowered back to the original position, the sliding frame 12 will also return to the original position, so that the connecting rod two 56 and the connecting rod one 53 return to the original position, the extrusion plate one 52 returns to the original position, the air inlet hole 511 is in communication with the side of the fixed frame one 51 close to the pedal 14 again, so that the external gas enters the fixed frame one 51, completing the replenishment of the gas in the fixed frame one 51;

[0056] Secondly, when the extrusion plate 1 52 moves, it will also drive the connecting rod 3 572 to move, the connecting rod 3 572 will push the extrusion plate 2 571 to move, the extrusion plate 2 571 will extrude the gas in the fixed frame 2 57, the extruded gas will enter the air jet pipe 573, and through the air jet pipe 573, the light gas will be sprayed to the user's feet, during the rotation of the pedal 14, the air jet pipe 573 will frequently spray the light gas to the user's feet, and the frequent spraying of the light gas will help to relax the user's feet and reduce the fatigue caused by using the pedal 14.
