[0034] In combination with the above and Figure 9 and Figure 10 , the working principle of the rotary switch lock 100 of the present application will be described in detail as follows:

[0035] When it is necessary to lock, the annular panel 11 is twisted to rotate the annular panel 11, and the arc-shaped slot 11a drives the first shaft pin 131a to slide from one end close to the center of the annular panel 11 to one end away from the center of the annular panel 11. In this process, the fan blade 131 rotates around the second shaft pin 131b, and thus the end of the fan blade 131 close to the center swings outward. At this time, the smallest adjusting hole 13a surrounded by all the fan blades 131 is enlarged to completely open the lock hole 1a. Then, the locking rod 21 and the lock cap 22 of the lower lock body 2 are inserted into the lock hole 1a of the upper lock body 1 and the lock cap 22 passes through the adjusting hole 13a. Then, the annular panel 11 is rotated in the opposite direction to make the end of the fan blade 131 swing toward the center, and finally the outer periphery of the locking rod 21 is reduced to the smallest adjusting hole 13a. At this time, the fan blade 131 can block the lock cap 22 from exiting the lock hole 1a; thus, the lower lock body 2 cannot be separated from the upper lock body 1, and the two are connected and locked with each other. At the same time, the clamping block 141 of the positioning mechanism 14 is opposite to the clamping recess 11b, and is clamped in the clamping recess 11b under the elastic force of the elastic reset member 142, thereby positioning the current position of the annular panel 11 to achieve a stable locking state. When it is necessary to unlock, the annular panel 11 is rotated again by applying force, so that the positioning mechanism 14 is automatically released from positioning, and then the lock hole 1a is opened through the fan blade 131 to achieve the purpose of unlocking.

[0036] Compared with the prior art, the utility model discloses a positioning mechanism 14 for positioning the annular panel 11, which effectively prevents accidental unlocking and is safer to use. The annular panel 11 is arranged on the upper lock body 1, the annular seat body 12 is arranged on the lower lock body 2, and the iris mechanism 13 is arranged on the annular panel 11. The iris mechanism 13 is driven by the rotation of the annular panel 11 relative to the annular seat body 12 to make the adjusting hole 13a of the iris mechanism 13 expand or shrink in the lock hole 1a. Therefore, when the lock cap 22 on the lower lock body 2 is inserted into the lock hole 1a and the adjusting hole, the size of the adjusting hole 13a can be adjusted to limit the entry and exit of the lock cap 22, so as to achieve the purpose of locking or separating the upper lock body 1 and the lower lock body 2. The upper lock body 1 and the lower lock body 2 are fixed on the opposite sides of the opening of the leather bag or the box body, so that the leather bag or the box body can be locked or unlocked, which is very convenient to use. In addition, the rotation opening and closing mode can realize diversified design, so that the appearance of the box bag lock buckle is more fashionable and individual. Furthermore, the rotation opening and closing mode is used for locking or unlocking, which is more stable in connection, and frequent opening and closing will not damage the lock body, and has high durability and reliability and long service life. Moreover, the positioning mechanism 14 is used for positioning the rotating annular panel 11, which effectively prevents accidental unlocking and is safer to use.

[0037] The above disclosed is only a preferred embodiment of the present application, and certainly cannot limit the scope of the present application, therefore equivalent changes made according to the patent application scope of the present application still belong to the scope covered by the present application.
