DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0023] The utility model provides a rearview mirror for an automobile.

[0024] In this embodiment, refer to Figure 1-2 The automobile rearview mirror includes a main body shell 1 and a connecting base 2, and also includes a connecting shaft assembly for rotatably connecting the main body shell and the connecting base. The connecting shaft assembly includes an outer sleeve 3, an inner shaft rod 4, a pressing sleeve 5 and a locking nut 6. The outer sleeve is sleeved outside the inner shaft rod. One end of the inner shaft rod is provided with a pressing step 7 pressed against the end of the outer sleeve, and the other end passing through the outer sleeve has a screw 8 threadedly connected to the locking nut. The pressing sleeve is sleeved between the inner shaft rod and the outer sleeve and is pressed by the locking nut.

[0025] In this embodiment, the main body shell and the connecting base adopt a unique connecting shaft assembly to realize the rotational connection between the main body shell and the connecting base. The connecting shaft assembly is composed of an outer sleeve, an inner shaft rod, a pressing sleeve and a locking nut, wherein the outer sleeve is sleeved on the outside of the inner shaft rod, and one end of the inner shaft rod is provided with a pressing step, and the other end is provided with a screw threadedly connected to the locking nut. The pressing sleeve is inserted between the inner shaft rod and the outer sleeve, and is fixed by the pressing action of the locking nut. This design makes the rotational connection between the rearview mirror main body shell and the connecting base more stable, the rotational fit is smoother, and the adjustment process is smooth. Through the setting of the locking nut, not only can the connection stability of the connecting shaft assembly be ensured, but also the disassembly and assembly of the rotating connection is convenient, and it is convenient for later maintenance and replacement.
