Referring to
In the present disclosure, when the second frame body 300 rotates around the main shaft 100, a contact force between the clamping groove 301 and the first pin 400 due to the fact that the clamping groove 301 abuts against the first pin 400 and rotates relative to the first pin 400, drives the first pin 400 and the main shaft 100 to move to the right against the elastic force of the elastic member 500. At the same time, the first pin 400 leaves the clamping groove 301 and abuts against the second frame body 300 under the elastic force of the elastic member 500. When the second frame body 300 rotates to a certain angle, a next clamping groove 301 adjacent to the first clamping groove 301 rotates to a position of the first pin 400, and the first pin 400 comes into contact with the next clamping groove 301. Under the action of the elastic member 500, the first pin 400 and the main shaft 100 move to the left, so that the first pin 400 is accommodated in the next clamping groove 301. Thus, one angular rotation of the second frame body 300 for driving the lens barrel to rotate by a fixed angle is completed. Further, in order to push the first pin 400 out of the clamping groove 301, a greater external force needs to be applied to the second frame body 300. Therefore, in a process of manual rotation, whether the first pin 400 is contained in the clamping groove 301 can be perceived by magnitude of the force with which the second frame body 300 is rotated. In the above description, “certain angle” refers to an angle formed between two adjacent clamping grooves 301. Therefore, it can be understood that in one rotation process, the rotation angle of the second frame body 300 is equal to the angle formed between two adjacent clamping grooves 301. Therefore, through setting the angle formed between the two adjacent clamping grooves 301, the rotation angle which may be 30°, 45°, 60° and so on in each rotation process can be controlled. Corresponding to the rotation angle of 30°, 45° or 60°, the number of clamping grooves 301 may also be 12, 8 or 6. The size of the angle between the two adjacent clamping grooves 301 and the number of clamping grooves 301 can be set otherwise according to actual needs of angle adjustment, the present disclosure does not make specific definition.
The flip-to-side mount according to the embodiment of the present disclosure has at least the following beneficial effects. In the disclosure, the first pin is driven to move out of the clamping groove by the rotation of the second frame body; after the first pin moves out of the clamping groove, the second frame body continues to rotate to a certain angle, and under the action of the elastic member, the first pin is driven to engage with a next clamping groove on the second frame body, so as to realize the control of the rotation angle. The present disclosure has high positioning accuracy, accurate rotation angle, and can implement fixed angle adjustment in a manual way without additional angle measuring equipment, thereby greatly saving the equipment cost and simplifying the operation procedure in the flip process.
