[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-7 The utility model is an instrument calibration auxiliary device, comprising a surveying device support column 1, a sleeve ring 2 is sleeved on the surface of the surveying device support column 1, a connecting seat 3 is fixedly connected to the surface of the sleeve ring 2, a rotation switching mechanism 4 and a buffer mechanism 5 are arranged on the inner side of the connecting seat 3, the rotation switching mechanism 4 comprises a rotating rod 41, a card slot A47, a pressure rod A48, a card slot B49 and a pressure rod B410, the rotating rod 41 is rotatably connected to the inner side of the connecting seat 3, a level ruler 42 is fixedly connected to the surface of the rotating rod 41, both sides of the level ruler 42 are provided with sliding grooves 43, a telescopic spring 44 is fixedly connected to the inner wall of the sliding groove 43, a card block 45 is slidably connected to the inside of the sliding groove 43 through the telescopic spring 44, a ball 46 is arranged on the end of the card block 45 away from the telescopic spring 44, the card slot A47 and the card slot B49 are both arranged on the inner side wall of the connecting seat 3, and the pressure rod A48 and the pressure rod B410 are both slidably connected to the side of the connecting seat 3.

[0029] In the initial state, the level ruler 42 remains horizontal with the connecting seat 3, and the clamping block 45 is in the clamping slot A47. When the clamping block 45 is clamped in the clamping slot A47, the level ruler 42 will be fixed in a horizontal state. At this time, no deflection will occur during calibration to affect the calibration accuracy.

[0030] The slot A47 is the same size as the slot B49. The top and sides of the level 42 are both provided with scales. The block 45 can be inserted into the slot B49. The scales on the top and sides of the level 42 facilitate the calibration of the level 42 in a vertical or horizontal state.

[0031] The ends of the pressing rod A48 and the pressing rod B410 away from the outer side of the connecting seat 3 are respectively located in the card slot A47 and the card slot B49. By pressing the pressing rod A48 or the pressing rod B410, the card block 45 inserted into the card slot A47 or the card slot B49 can be squeezed out.

[0032] The buffer mechanism 5 includes a buffer spring 51, a buffer plate 52 and deceleration particles 54. The buffer plate 52 is slidably connected to the inner side of the connecting seat 3 through the buffer spring 51. The top of the buffer plate 52 is fixedly connected to a contact rod 53. The deceleration particles 54 are fixedly connected to the inner wall of the connecting seat 3.

[0033] The buffer plate 52 is located at the end of the connecting seat 3 away from the rotating rod 41, and the end of the contact rod 53 away from the buffer plate 52 is close to the deceleration particle 54. When the level ruler 42 switches from a vertical state to a horizontal state, it will contact the buffer plate 52. During the up and down movement of the buffer plate 52, the contact rod 53 will be driven to contact the deceleration particle 54.

[0034] One end of the contact rod 53 away from the buffer plate 52 is arc-shaped, and the deceleration particles 54 are made of rubber. When the arc-shaped end of the contact rod 53 contacts the deceleration particles 54 , compression will occur to generate resistance.

[0035] A specific application of this embodiment is: when it is necessary to switch the level ruler 42 from a vertical state to a horizontal state, the pressure rods A48 on both sides of the connecting seat 3 are pressed, and the block 45 inserted into the card slot A47 is squeezed out by the pressure rods A48. When the block 45 leaves the card slot A47, the level ruler 42 can be rotated to make it horizontal. At this time, the ball 46 at the front end of the block 45 contacts the inner side wall of the connecting seat 3, and the telescopic spring 44 is tightened. The ball 46 can reduce the friction force to prevent the front end of the block 45 from directly When the friction force with the inner wall of the connecting seat 3 is large and the level ruler 42 is difficult to rotate, when the level ruler 42 rotates and drives the slide groove 43 to correspond to the card slot B49, the telescopic spring 44 rebounds and drives the card block 45 to be clamped into the card slot B49. At this time, the level ruler 42 becomes horizontal, and the card block 45 is clamped into the card slot B49 to fix the level ruler 42 to prevent deflection during calibration that affects the calibration accuracy. When it is necessary to switch back to the vertical state, the pressure rods B410 on both sides of the connecting seat 3 are pressed to drive When the block 45 leaves the slot B49, the level ruler 42 can be rotated again to switch it back to the vertical state. At this time, the block 45 is re-engaged in the slot A47, and the pressure rod A48 is pushed back to its original state by the elastic force of the telescopic spring 44. The operation is simple and convenient, and the calibration efficiency is effectively improved. In the process of switching the level ruler 42 from the vertical state to the horizontal state, the level ruler 42 will contact the buffer plate 52 and drive the buffer plate 52 to press the buffer spring 51. At this time, the buffer spring 51 will absorb the downward impact force of the level ruler 42. At the same time, the buffer plate 52 will drive the contact rod 53 to contact the deceleration particles 54 when moving. The arc-shaped end of the contact rod 53 contacts the deceleration particles 54 to generate resistance. The buffer spring 51 absorbs the impact force and the resistance generated by the extrusion of the contact rod 53 and the deceleration particles 54 to reduce the tension and rebound amplitude of the buffer spring 51. The two cooperate to provide a buffering protection for the level ruler 42 to prevent the level ruler 42 from being damaged by excessive downward impact force due to factors such as gravity.
