10. The method for using the dry gas sealing ring end surface flatness rapid detection tool according to claim 9, comprising the following steps: a1. When using the device to detect the end surface flatness of the dry gas sealing ring body (5), the dry gas sealing ring body (5) is first placed on the upper end of the circular placement plate (41), and then the electric telescopic rod (42) is started to drive the corresponding clamping block (45) to move in the direction of the dry gas sealing ring body (5). During this process, the other three clamping blocks (45) can be driven to move in the direction of the dry gas sealing ring body (5) at the same time under the cooperation of the meshing gear (410) and the four L-shaped tooth plates (49). At this time, The four clamping blocks (45) are used to clamp and fix the dry gas sealing ring body (5). After the dry gas sealing ring body (5) is clamped and fixed, the second electric telescopic rod (66) is started to drive the mounting plate (616) to move downward, and then the detection roller (614) is driven to overlap the upper end of the dry gas sealing ring body (5) under the cooperation of the concave frame (63), the sliding seat (610), the connecting rod (69) and the mounting seat (613), and the two springs (612) are in a squeezed state. a2. After the above operation is completed, the electric telescopic rod 3 (71) is started to drive the T-shaped plate (75) to move to the left, and then the rotating rod (78) can be driven to rotate under the cooperation of the meshing tooth plate (74) and the meshing gear 2 (76). The rotation of the rotating rod (78) can drive the fixed component (4) to rotate, thereby achieving the effect of driving the dry gas sealing ring body (5) to rotate. When the flatness of the end surface of the dry gas sealing ring body (5) changes, the distance between the mounting seat (613) and the sliding seat (610) will change accordingly under the cooperation between the provided detection roller (614), the connecting rod (69) and the spring (612). At this time, the infrared rangefinder body (611) and the rangefinder plate (615) can be set. The change in the distance between the mounting seat (613) and the fixed seat is displayed on the display screen body (2). At the same time, with the cooperation of the provided connecting rod (69), the L-shaped indicator arrow (68) and the scale plate (67), the change in the distance between the fixed seat and the mounting seat (613) can also be displayed intuitively in real time. The rotation of the threaded rod (65) can drive the sliding seat (610) to move in the left and right directions under the action of the provided limiting rod 2 (64). Then, with the cooperation of the provided connecting rod (69) and the mounting seat (613), the detection roller (614) can be driven to move in the left and right directions. Therefore, the device can conveniently adjust the position of the detection roller (614) in the left and right directions according to the size of the dry gas sealing ring body (5) to be detected.
