The automobile gear testing tool convenient to mount and dismount as claimed in claim 1, wherein: one side fixed surface of fixture block one (22) is connected with telescopic link three (24), the end fixedly connected with briquetting (26) of telescopic link three (24), one side surface of briquetting (26) and the laminating of one side surface of pole setting (21), the surface activity of telescopic link three (24) has cup jointed spring one (25), the one end and the fixture block one (22) fixed connection of spring one (25), the other end and the briquetting (26) fixed connection of spring one (25).

9. The detection method of the automobile gear detection tool convenient to assemble and disassemble as claimed in claim 1, is characterized by comprising the following steps:

the method comprises the following steps that firstly, a gear to be detected is placed at the top end of a clamping seat (13), the clamping seat (13) moves along with the movement of a bottom block (10), the height of the top end of the clamping seat (13) is sequentially reduced to form a step shape, the gear can be supported and fixed from the inside by extruding the inner wall of the gear, the detection of the outer teeth of the gear is facilitated, meanwhile, the bottom end of the gear is clamped through three clamping seats (13), and gears of different models can be fixed by using fixing modes of various forms;

step two, tension exists between the first spring (25) and the pressing block (26), the tension of the first spring (25) on the pressing block (26) can improve the friction force between the pressing block (26) and the vertical rod (21), so that the braking effect on the first clamping block (22) is achieved, the height of the cross rod (27) is controlled, and the position of the cross rod (27) can be moved to the upper surface of the gear to be measured by matching with the telescopic adjustment of the second telescopic rod (23);

thirdly, the bottom ends of the ejector rods (34) in the two fixture blocks II (31) are attached to the upper surface of the gear to be measured, the ejector rods (34) in the two fixture blocks II (31) can drive the balance rod (29) to move to tilt up and down when the heights of the ejector rods (34) are changed, and the tilt change of the balance rod (29) can be clearly and visually observed through the level gauge (30), so that whether the gear fixed on the clamp seat (13) is in a horizontal state or not can be judged, and an operator can conveniently adjust the gear in time;

step four, a second starting motor (14) drives a driving gear (15) to rotate, the rotating driving gear (15) drives a wheel disc (2) to rotate, the gear fixed on the clamping seat (13) rotates simultaneously, the position height of the mu-level indicating meter (19) can be adjusted through a first telescopic rod (16), a detection needle (20) is conveniently aligned to the gear teeth on the gear, a sliding bottom sliding block (18) drives the mu-level indicating meter (19) to move, and the gear teeth on the gear are detected by the detection needle (20).
