[0034] See also Figures 1 to 4 , Fig. 9 A bracket opening and closing mechanism includes a shell 100, a bracket rod 200, a locking unit 300 and an unlocking unit 400. An opening and closing position 110 is provided on the shell 100, and a rod positioning shaft 120 is provided on both sides of the opening and closing position 110. A rod spring 130 is sleeved on the rod positioning shaft 120. Both sides of the bracket rod 200 are respectively sleeved on the rod positioning shaft 120 on both sides and abut against the rod spring 130. The bracket rod 200 can move along the rod positioning shaft 120. The locking unit 300 and the unlocking unit 400 are installed at the opening and closing position 110, and the locking unit 300 is respectively connected with the bracket rod 200 and the unlocking unit 400. The locking unit 300 is used to lock the moving position of the bracket rod 200, and the unlocking unit 400 is used to unlock the locking unit 300, and the bracket rod 200 is driven to reset by the rod spring 130.

[0035] Specifically, in this embodiment, the locking unit 300 and the unlocking unit 400 are respectively arranged at the opening and closing position 110, and the two sides of the bracket rod 200 are respectively sleeved on the rod positioning shaft 120 and connected to the locking unit 300. In the initial state, the bracket rod 200 is in an open state under the action of the rod spring 130, and the user can directly place the electronic product (mobile phone, game console, tablet, etc.) at the opening and closing position 110 of the shell 100. After placement, the user pushes the outermost side of the bracket rod 200 with one hand to retract the bracket rod 200 until the bracket rod 200 clamps the electronic product at the opening and closing position 110. At this time , the user releases the outermost side of the bracket rod 200, and the bracket rod 200 is locked by the locking unit 300. After locking, the bracket rod 200 can clamp the electronic product steadily without the risk of slipping due to external force shaking, thereby ensuring the clamping stability. When the electronic product needs to be removed, the user only needs to turn the unlocking unit 400 to unlock the locking unit 300. After the locking unit 300 is unlocked, the elastic force of the rod spring 130 itself will drive the bracket rod 200 to reset, thereby forming an open state again, and finally the opening and closing mechanism can be operated with one hand when in use, thereby improving the convenience of operating the opening and closing mechanism.

[0036] See also Figures 3 to 5 In order to lock the bracket rod 200, in this embodiment, a first one-way rack 210 is respectively arranged on both sides of the bracket rod 200. At the same time, the locking unit 300 includes two groups of relatively arranged locking blocks 310, and a locking spring 320 is arranged between the two groups of locking blocks 310. The two ends of the locking spring 320 are respectively abutted against the two groups of locking blocks 310. A second one-way rack 311 is arranged on the side of the locking block 310 far away from the locking spring 320, and the second one-way rack 311 is meshed with the first one-way rack 210.

[0037] When the support rod 200 is connected with the two sets of locking blocks 310, the second one-way racks 311 of the two sets of locking blocks 310 will respectively mesh with the first one-way racks 210 on both sides of the support rod 200, and after meshing, due to the meshing direction of the one-way teeth, the support rod 200 can only be pushed inward and cannot be pulled out. Therefore, at the beginning, the support rod 200 is in an open state under the action of the rod spring 130, and then the user places the electronic product to the opening and closing position 110. After placement, the user pushes the support rod 200, and the support rod 200 will act on the two sides simultaneously during the movement. The two sets of locking blocks 310 will relatively squeeze the locking spring 320, so that the first one-way rack 210 can mesh and move relative to the second one-way rack 311 until the bracket rod 200 clamps the electronic product. When the user loosens the bracket rod 200, due to the meshing direction of the one-way teeth, the bracket rod 200 will not pop outward due to the action of the rod spring 130. The two sets of locking blocks 310 will lock the two sides of the bracket rod 200, so that the bracket rod 200 can clamp the electronic product steadily without the risk of slipping due to external force shaking, thereby ensuring the clamping stability.

[0038] See also Figure 3 , Figure 5 and Figure 6 When the electronic product needs to be removed from the opening and closing position, the locking unit 300 needs to be unlocked in order to open the bracket pull rod 200.

The unlocking slider 410 is provided with a driving inclined surface 411 that cooperates with the sliding surface 312. When the unlocking slider 410 moves, the driving inclined surface 411 acts on the sliding surface 312, thereby causing the two groups of locking blocks 310 to move toward or away from each other. One end of the unlocking spring 420 abuts against the unlocking slider 410, and the other end abuts against the side wall of the opening and closing position 110.

[0039] When the locking unit 300 is connected to the unlocking unit 400, the inclined sliding surface 312 of the locking block 310 is connected to the driving inclined surface 411 of the unlocking slider 410. When unlocking, the unlocking slider 410 is toggled to move the unlocking slider 410. When the unlocking slider 410 moves, it squeezes the unlocking spring 420 and moves with the driving inclined surface 411. The driving inclined surface 411 acts on the sliding surface 312 of the locking block 310 during the movement, so that the two sets of locks are locked. The fixed blocks 310 move toward each other. When the two sets of locking blocks 310 move toward each other, they will squeeze the locking spring 320 and separate the second one-way rack 311 from the first one-way rack 210. At this time, under the action of the pull rod spring 130, the bracket pull rod 200 will be directly driven to reset to form an open state, thereby unlocking the bracket pull rod 200. Finally, by moving the unlocking slide 410, the bracket pull rod 200 can be directly opened and reset, making it convenient to remove the electronic product, thereby making the opening and closing of the bracket convenient and simple to operate.
