This facilitates the user to press the pressing lever 210.
In certain embodiments of the first aspect of the present invention, the first elastic member 231 is disposed between the fastening member 220 and the bottom surface of the mounting groove 120. When the pressing rod 210 is pressed and the locking element 220 retracts into the mounting groove 120, the first elastic element 231 is in a compressed state under the action of the locking element 220, and the first elastic element 231 tends to move the locking element 220 toward the first notch 121. When the pressing rod 210 is released, the locking member 220 moves toward the first notch 121 under the action of the first elastic member 231, and the movement range of the pressing rod 210 and the locking member 220 is limited by the cooperation of the limiting protrusion 221 and the limiting groove 211, so that the pressing rod 210 and the locking member 220 are prevented from being separated from the mounting groove 120, and the locking member 220 is prevented from being restored to the original position.

Specifically, the second elastic member 232 is a spring.
When the pressing rod 210 is pressed, the second elastic member 232 is in a compressed state under the action of the pressing rod 210, and the second elastic member 232 tends to move the pressing rod 210 toward the second notch 122. When the pressing rod 210 is released, the pressing rod 210 moves toward the second notch 122 under the action of the second elastic member 232, and the movement range of the pressing rod 210 and the locking member 220 is limited by the cooperation of the limiting convex member 221 and the limiting groove 211, so that the pressing rod 210 and the locking member 220 are prevented from being separated from the mounting groove 120, and the pressing rod 210 is prevented from being reset to the original position.
Referring to fig. 4, in some embodiments of the first aspect of the present invention, the fastening member 220 is provided with a first inclined surface 222, and the first inclined surface 222 is used for changing the direction of the acting force of the pressing rod 210 on the fastening member 220; one end of the pressing lever 210 abuts against the first inclined surface 222.
Since the first notch 121 is disposed on the side of the frame 100 facing the lens and the second notch 122 is disposed on the outer side of the frame 100, the first notch 121 and the second notch 122 are not in the same straight line; when the pressing rod 210 moves toward the locking member 220, the locking member 220 needs to be driven to retract into the mounting groove 120, and the moving direction of the pressing rod 210 is different from the moving direction of the locking member 220. Therefore, the direction of the acting force of the pressing rod 210 on the fastener 220 is changed by the first inclined surface 222, so that when the pressing rod 210 moves towards the fastener 220, the pressing rod 210 has an acting force towards the first elastic element 231 on the fastener 220, so that the fastener 220 retracts towards the mounting groove 120 and compresses the first elastic element 231.
Specifically, the first inclined surface 222 is an inclined surface gradually inclined upward from the direction approaching the pressing rod 210 to the direction away from the pressing rod 210, with the first notch 121 as the upward direction and the bottom surface of the mounting groove 120 as the downward direction.

When the pressing rod 210 and the locking member 220 are not affected by external force, the longitudinal protrusion 223 of the limiting protrusion 221 is inserted into the limiting groove 211, the side surface of the longitudinal protrusion 223 abuts against a side surface of the limiting groove 211 close to the locking member 220, the top surface of the transverse protrusion 224 abuts against the bottom surface of the pressing rod 210 or the top surface of the longitudinal protrusion 223 abuts against the upper groove surface of the limiting groove 211, so that the pressing rod 210 cannot continue to move toward the second groove opening 122 under the elastic force of the second elastic member 232, and the locking member 220 cannot continue to move toward the first groove opening 121 under the elastic force of the first elastic member 231. When the pressing rod 210 is pressed, the pressing rod 210 moves toward the locking member 220, the pressing member compresses the second elastic member 232, the second inclined surface 212 of the pressing member abuts against the first inclined surface 222 of the locking member 220, so that the locking member 220 retracts into the mounting groove 120 along with the movement of the pressing member, the locking member 220 compresses the first elastic member 231, the limiting protrusion 221 moves downward relative to the pressing rod 210, and the limiting groove 211 moves along with the pressing rod 210 toward the locking member 220. When the pressing rod 210 is released, the locking member 220 moves toward the first notch 121 under the elastic force of the first elastic member 231, the pressing rod 210 moves toward the second notch 122 under the elastic force of the second elastic member 232, and at this time, the first inclined surface 222 always collides with the second inclined surface 212 until the longitudinal protrusion 223 of the limiting protrusion 221 is inserted into the limiting groove 211, the side surface of the longitudinal protrusion 223 collides with a side surface of the limiting groove 211 close to the locking member 220, the top surface of the transverse protrusion 224 collides with the bottom surface of the pressing rod 210 or the top surface of the longitudinal protrusion 223 collides with the upper groove surface of the limiting groove 211, so that the pressing rod 210 cannot continue to move toward the second notch 122 under the elastic force of the second elastic member 232, and the locking member 220 cannot continue to move toward the first notch 121 under the elastic force of the first elastic member 231. The pressing rod 210 and the locking member 220 are both reset to the position where they are not acted by external force.
In the process of pressing the pressing lever 210, the longitudinal protrusion 223 of the stopper protrusion 221 may be disengaged from the stopper groove 211, or a part of the longitudinal protrusion 223 may be inserted into the stopper groove 211 all the time. For the situation that part of the longitudinal convex pieces 223 are inserted into the limiting grooves 211 all the time, the situation that the longitudinal convex pieces 223 are not inserted into the limiting grooves 211 any more and are separated from the limiting grooves 211 in the resetting process can be avoided. When the pressing rod 210 is released, the longitudinal protrusion 223 is separated from the limiting groove 211, and the longitudinal protrusion 223 is no longer matched with the limiting groove 211 to limit the moving range of the pressing rod 210 and the locking element 220, the pressing rod 210 will leave the mounting groove 120 from the second notch 122, and the locking element 220 will leave the mounting groove 120 from the first notch 121.
