The invention discloses a hopper clamp used for food bag filling. The hopper clamp comprises a hopper, a clamping device and a handle, and is characterized in that the clamping device comprises a clamping main rod, clamping semi-rings and a sleeving connection opening; one end of the clamping main rod is connected with two clamping branch rods; each clamping branch rod is connected with a main supporting lever in a rigid manner; the lower end of each main supporting lever is connected with the corresponding clamping semi-ring; a branch supporting lever is arranged on the side face of each mainsupporting lever; a driven rod is hinged to the tail end of each branch supporting lever; the lower end of each driven rod is connected with the corresponding clamping semi-ring; a compression springis arranged between the clamping main rod and a handle rod; and each driven rod is provided with a rotation hole and is connected to the hopper through a pin. By means of the hopper clamp, the food processing filling speed can be increased, waste of food can be reduced, manpower and financial resources can be saved, the production efficiency can be improved, and the quality of daily life of people is also improved.
