Portable aluminum profile for paper clamping device

The utility model discloses an aluminum profile for a portable paper clamping device, which comprises a main body frame and a gravity limiter, a vertical accommodating cavity is arranged in the main body frame, the gravity limiter is placed in the accommodating cavity, and the gravity limiter falls to the inlet end of the accommodating cavity under the action of the gravity of the gravity limiter. The size of the inlet end of the containing cavity is smaller than that of the gravity limiting stopper, so that the gravity limiting stopper blocks the inlet end of the containing cavity, and paper is pressed by the gravity limiting stopper after being inserted between the gravity limiting stopper and one side face of the containing cavity. The paper clamping and taking-out device is simple and compact in structure, paper is pressed through the gravity limiting stopper, paper clamping and paper taking-out are facilitated, operation is convenient, the operation difficulty is reduced, and the whole paper clamping and
