[0027] The utility model provides Figure 1-6The manual folder for the exterior rearview mirror of an automobile shown in the figure comprises a base 4, wherein a positioning shaft 5 and a metal shaft 6 are sequentially arranged inside the base 4, and a spring clamp 1 is clamped on the outer ring of the metal shaft 6, and the spring clamp 1 is in contact with a spring 2 movably connected inside the base 4, and the spring 2 is movably sleeved on the outer ring of the metal shaft 6, and the bottom of the spring 2 is in contact with a wear-resistant sheet 3 arranged at the inner step of the base 4.

[0028] The metal rotating shaft 6 is composed of shaft body 1 61, shaft body 2 62, elastic ring plate 63 and fitting groove 64, and the elastic ring plate 63 is fixedly connected to the bottom of shaft body 1 61, and the outer circle diameter of the elastic ring plate 63 is smaller than the outer circle diameter of shaft body 1 61, and the inner circle diameter of the elastic ring plate 63 is equal to the inner circle diameter of shaft body 1 61, ensuring that the contact surfaces of shaft body 1 61, shaft body 2 62 and the inner wall of the elastic ring plate 63 are at the same level.

[0029] The shaft body 1 61, the elastic ring plate 63 and the shaft body 2 62 are movably connected through the mounting assembly 8 to ensure that the shaft body 1 61 and the shaft body 2 62 are detachable so as to monitor the performance of the spring 2;

[0030] The gap between the bottom of the first shaft body 61 and the top of the second shaft body 62 is a retaining groove 7, and a spring retaining ring 1 is engaged inside the retaining groove 7.

[0031] A fitting groove 64 is reserved at the top of the second shaft body 62, and the inner wall of the fitting groove 64 is in contact with the outer wall of the elastic ring plate 63 and is slidably connected up and down, ensuring that the first shaft body 61 and the elastic ring plate 63 are easily installed.

[0032] The mounting assembly 8 consists of a notch 81, a snap-fit ​​block 82, a snap-fit ​​groove 83, a limit block 84 and a limit groove 85, wherein the notch 81 is provided in two groups with a total of four locations, and each group of two symmetrical notches 81 vertically penetrates the interior of the elastic ring plate 63, and the two groups of notches 81 divide the elastic ring plate 63 into two groups of symmetrical and equal-sized A blocks and two groups of symmetrical and equal-sized B blocks, wherein the area of ​​the A block is larger than that of the B block, so that the two symmetrical B blocks can be moved conveniently.

[0033] The outer side walls of the two symmetrical B body blocks in the elastic ring plate 63 are fixedly connected with a snap-fit ​​block 82, and the snap-fit ​​block 82 matches the snap-fit ​​groove 83 reserved inside the shaft body 62, and the snap-fit ​​groove 83 is connected to the fitting groove 64. The two symmetrical B body blocks can be driven to move by moving the snap-fit ​​block 82, so that the snap-fit ​​block 82 leaves the inside of the snap-fit ​​groove 83, thereby facilitating the removal of the shaft body 1 61 and the shaft body 2 62 so as to remove the spring retaining ring 1 and test the performance of the spring 2.
