When in use: placing the mobile phone on the abutting claw 23, wherein the abutting claw 23 moves downwards relative to the fixed support 10 under the action of the gravity of the mobile phone, the first meshing groove 232 of the abutting claw 23 and the lower end of the step gear 21 are meshed to drive the step gear 21 to rotate, the upper end of the step gear 21 is meshed to the second meshing groove 112 of the upper support 11, and the step gear 21 moves downwards relative to the third movable hole 111 (moves downwards relative to the whole fixed support 10), so that the step gear 21 moves downwards relative to the two first movable holes 221, and then the two clamping claws 22 are driven to approach relatively to clamp the mobile phone; due to the adoption of the design of the step gear 21 (similar to a bicycle speed changer), under the condition of pressing under the same gravity, the clamping force of several times of the gravity of the mobile phone can be generated, so that the novel gravity support can clamp the mobile phone more stably;

and the design of the constant force spring 30 is adopted, so that the two clamping claws 22 can keep constant force between the maximum opening angle and the minimum opening angle, the loosening state of the opening angle of the two clamping claws 22 can be always kept, and the noise can be avoided.

It should be noted that, the gravity bracket in the market all adopts a common-stage compression spring, and belongs to a variable force spring, and the maximum and minimum force difference of the spring is more than 2 times, which may cause the following problems:

1. when the two clamping claws 22 are in the maximum opening state, the spring force is the minimum, and the whole body is in a loose state, so that when the gravity bracket shakes and shakes, the spring force is small, and the inertia force caused by oscillation cannot be overcome, so that noise is generated, and certain influence is caused on people;

2. when the two clamping jaws 22 are in the minimum opening state, the state is generally suitable for small mobile phones, the weight of the small mobile phones is small, the generated gravity is also minimum, but the spring force is maximum, so when the gravity is smaller than the spring force, the gravity cannot clamp the small mobile phones;

thus, the design of the constant force spring 30 completely avoids both of the above problems.

The first engaging groove 232 is provided with a first tooth opening 2321 matched with the lower end of the step gear 21.
