Before riveting, the vertical distance between the bottom surface of the 3 rd plane 8-7 and the 8-14 th plane 8-3 and the upper surface of the 1 st plane 8-3 is slightly larger than the vertical distance between the adjusting shaft shoulder 7-1 and the corresponding upper surface of the 1 st bracket 5 after riveting, the elastic indicating sheet 8 is higher than the two convex keys 6-2 of the cam, but due to the existence of the 2 nd plane 8-5 and the 8-15 th plane 8-2, the two square grooves 8-2 are clamped into the two convex keys 6-2 of the cam and cannot fall off. After riveting, the adjusting shaft shoulder 7-1 contacts the top of the cam protruding key 6-2, the upper surface of the 1 st plane 8-3 of the elastic indicating sheet 8 is in contact connection with the adjusting shaft shoulder 7-1, the bottom surfaces of the 2 nd, 4 th planes 8-5 and 8-15 are in contact connection with the upper surface of the cam cylindrical table 6-1, the two square grooves 8-2 are matched, positioned and fixedly connected with the cam protruding key 6-2, the elastic indicating sheet 8 rotates along with the cam adjusting shaft assembly, at the moment, the bottom surfaces of the 3 rd, 5 th planes 8-7 and 8-14 are in movable contact connection with the corresponding upper surface of the 1 st bracket 5, and as the vertical distance between the bottom surfaces of the 3 rd, 5 th planes 8-7 and 8-14 and the upper surface of the 1 st plane 8-3 in the initial state is slightly larger than the vertical distance between the adjusting shaft shoulder 7-1 and the corresponding upper surface of the 1 st bracket 5 after riveting, therefore, the 3 rd plane 8-7 and the 5 th plane 8-14 are elastically compressed, a certain friction force is generated when the adjusting shaft 7 is rotated, and a turning moment with moderate hand feeling is generated. In addition, the height of the two vertical feet 8-10 of the elastic indicating sheet 8 is shorter than the vertical distance between the riveted adjusting shaft shoulder 7-1 and the corresponding upper surface of the 1 st bracket 5, and in a normal state, when the adjusting shaft 7 is rotated, the vertical feet 8-10 can not contact with the corresponding upper surface of the 1 st bracket 5, but when the adjusting shaft 7 is subjected to axial pressure applied from the outside, the vertical feet 8-10 can be in contact connection with the corresponding upper surface of the 1 st bracket 5, so that the adjusting shaft 7 is prevented from being further pressed down to cause damage. In addition, the indication points 8-9 at the front end parts of the 3 rd planes 8-7 can be matched with the corresponding different angle marking lines on the 1 st bracket 5 to indicate and determine the rotation angle position of the cam adjusting shaft assembly.

In this example, the elastic indicating sheet 8 is made of a hard stainless steel sheet with a thickness of 0.4mm, and by controlling the vertical distance between the 3 rd plane 8-7 and the 5 th plane 8-14 and the 1 st plane 8-3, a turning moment of 0.02 to 0.06Nm can be obtained.
