[0042] Wherein, as some embodiments of the present application, the positioning mounting rod 1 can be assembled on the cylinder block of the engine through bolts. As some embodiments of the present application, the positioning mounting rod 1 can be clamped on the cylinder block of the engine so that the positioning mounting rod 1 is mated and assembled with the engine, thereby enabling the angle marker fixing device 100 to be assembled on the engine through the positioning mounting rod 1. As some embodiments of the present application, an external thread can be formed on the peripheral wall of the positioning mounting rod 1, and a through hole can be formed in the first mounting member 2. By passing the positioning mounting rod 1 through the through hole of the first mounting member 2, and along the axial direction of the positioning mounting rod 1, fastening nuts are installed on both sides of the first mounting member 2, and the fastening nuts can fix the first mounting member 2 on the positioning mounting rod 1. As some embodiments of the present application, the first mounting member 2 can also be fixed on the positioning mounting rod 1 through bolts.
[0043] In some embodiments of the present application, the second mounting member 3 can be provided on the first mounting member 2 by bolts.

Along the first direction, the first direction is perpendicular to the axial direction of the positioning and mounting rod 1, that is Figure 1 the X direction in [description], the position of the second mounting member 3 relative to the first mounting member 2 is adjustable. For example, a strip-shaped hole is formed on the first mounting member 2 or the second mounting member 3, or strip-shaped holes are formed on both the first mounting member 2 and the second mounting member 3. By passing the bolt through different positions of the strip-shaped hole and tightly connecting it with the corresponding nut, the second mounting member 3 can be set at a suitable position on the first mounting member 2.

For example, a strip-shaped hole is formed on the third mounting member 4. By setting the fourth mounting member 5 at different positions of the strip-shaped hole, the fourth mounting member 5 can be set at a suitable position on the third mounting member 4. Such a setting can make the position of the fourth mounting member 5 in the second direction reasonable. The fourth mounting member 5 is used to mount the angle indicator 200, so that the angle indicator 200 can be fixed on the angle indicator fixing device 100 through the fourth mounting member 5.
