Abstract: A vehicle air vent clamping device is disclosed. The vehicle air vent clamping device includes a base, a supporting arm, a hook for hooking a blade of a vehicle air vent, and an adjustment mechanism for driving the hook to move. The rear end of the supporting arm is connected to the base, and a blocking portion is disposed at the front end of the supporting arm. The hook can be located on the supporting arm in a front-rear movement manner, and when the hook moves to the position of the blocking portion, the hook is hidden in the blocking portion. The adjustment mechanism is connected between the base and the hook.

Abstract: A phone gravity holder comprises a base, a pull rod configured to hold the phone, and a left clamping arm and a right clamping arm configured to clamp the phone, wherein the base is provided with a positioning shaft, the left clamping arm and the right clamping arm are both mounted on the positioning shaft in a rotatable manner, and the pull rod is respectively in transmission connection with the left clamping arm and the right clamping arm, respectively. When the phone is used, the phone is directly placed on the pull rod, and under the gravity effect of the phone, the pull rod drives the left clamping arm and the right clamping arm to rotate in reverse to clamp the phone. The phone can be clamped automatically by utilizing the gravity of the phone and simple mechanical principles, the structure is simple, and the production cost is greatly reduced.
