The technical problem to be solved by the present invention is to provide a screw-driven mobile phone holder with better clamping effect, easy use, better user experience and long service life, aiming at the deficiencies of the prior art.

In order to solve the above technical problems, the present invention adopts the following technical solutions.

A screw-driven mobile phone bracket includes a casing, a fixed clamping arm and a movable clamping claw are arranged on the casing, and the movable clamping claw can slide back and forth relative to the casing. There is a screw and a motor for driving the screw to rotate. The screw is sleeved with a screw pair and the two are in driving cooperation. The movable jaw is connected to the screw pair. When the motor is running, it is The cooperation of the screw rod and the screw pair drives the movable clamping claw to move in translation, so that the movable clamping claw is close to or away from the fixed clamping arm.

In the screw-driven mobile phone bracket disclosed in the present invention, a fixed clamping arm is arranged on the casing, and a movable clamping claw that can move relative to the fixed clamping arm is arranged at the same time. When the motor in the casing is running, The screw and the screw pair cooperate with each other, and the screw pair drives the screw pair to translate, and then the screw pair drives the movable gripper to move, so that the movable gripper is close to or away from the fixed gripping arm. The cooperation of the movable clamping claw and the fixed clamping arm implements the loosening action of the mobile phone. Compared with the prior art, the present invention not only has better clamping effect, but also does not need to manually open the jaws. It can be seen that the present invention is easier to use and has better user experience. At the same time, the present invention only needs one jaw movement. It can effectively reduce the wear and tear during the sliding process of the jaws, so that the service life of the product is longer.
