The mobile phone uses dual shafts and adopts a gear structure to realize synchronous flipping. The flipping damping depends on the structure of the customer's product. The specific technical parameters are as follows:

      1. The spring force can be adjusted appropriately to increase or decrease according to customer requirements.

     2, the working angle of the shaft is open 0°～167°, 0°, 167°, there is a positioning feel. 0° preload 10 degrees.

     3. Hand feel requirements: 0 degree snapping screen feels strong, 167°, 345° positioning sense is obvious.

     4. Shipping angle: open to 167°.

     5. Lifetime requirement: 100,000 times, test angle: 0°-165°, 3-4S/round, one round is once, decay rate ±30%.

     6. After the shaft is assembled to the whole machine, skew, warp, screen drop, and gap deviation are not allowed.

     7. Pay attention to the assembly direction of the product and the phone case.
