At the same time, because the locking plate body 331 is displaced toward the back plate 11, the locking The piercing hole 333 of the plate 33 will be pierced by the post 321, in other words, the post 321 of the elastic member 32 will respectively pass through the piercing hole 333 of the locking plate 33, so that The posts 321 are respectively located in the through holes 333 .

It is worth mentioning that when the button 71 is pressed and the turntable body 41 is rotated so that the locking hole 43 does not correspond to the locking protrusion 334, the turntable body 41 is within a certain rotation range. It will not be restricted by the locking mechanism 3, but once the turntable body 41 is turned to the position where the locking hole 43 corresponds to the locking projection 334, the locking projection 334 will be supported by the elastic member. 32, so that the locking projections 334 respectively extend into the locking holes 43, and push away the unlocking projections 712 originally located in the locking holes 43, so that the button 71 returns to the locking position again, and the rotation of the turntable body 41 is also locked and fixed by the locking mechanism 3 again. In addition, referring back to FIG. 5, since the limit post 45 of the turntable 4 is always located in the limit space 13, even if the button 71 is in the unlocking position, the turntable 4 will still be pressed by the limit wall. 12 blocks, thus limiting the rotation only within a certain range.

In summary, the turntable 4 disclosed by the rotary photo frame support device of the present invention enables the pivot support 6 to rotate around the shaft 2, which increases the use of the rotary photo frame support device of the present invention. In addition, further Cooperating with the locking mechanism 3 and the unlocking mechanism 7, when the pivoting bracket 6 rotates to a certain position, it can be fixed and will not rotate again. At the same time, the button 71 of the unlocking mechanism 7 is also It is very convenient for users to press, so the purpose of the present invention can indeed be achieved.

But the ones described in the above items are only preferred embodiments of the present invention, and should not limit the scope of the present invention with this, that is, all simple equivalent changes and modifications made according to the claims of the present invention and the content of the description of the invention, All still belong to the scope that the patent of the present invention covers.
