Furthermore, the piston comprises a movable rod and a piston sheet, a fixed rod is arranged at the opening of the cavity, a hole is formed in the fixed rod, the movable rod is clamped in the hole, and the piston sheet is connected with the movable rod and is arranged in the cavity.

The utility model discloses an discrepancy of motion control butter of piston in the cavity, when the butter gun absorbs the butter, the piston has the opening part to rise to in the cavity, and the butter flows from the edge in the cavity. After the grease gun finishes sucking, the piston sheet descends to the opening end of the check valve to prevent the grease from sinking.

Further, the fixing rod is fixed at the opening end of the cavity or fixed on the oil absorption disc body.

Further, the diameter of the piston is larger than the diameter of the opening end and smaller than the diameter of the inner part of the cavity.

Furthermore, another open end of cavity is equipped with the oil scraping rod of transverse connection, can trowel the butter of grease gun tip after rotatory with grease gun tip, has avoided the overflow of butter in the grease gun.

Furthermore, an opening at one end of the cavity is provided with an external thread which is connected and matched with the oil absorption disc body.

Furthermore, an opening at the other end of the cavity is provided with an internal thread matched with the grease gun.

Further, the check valve is provided at the center of the oil suction pan body.

Compared with the prior art, the beneficial effects are:

the utility model discloses an inhale the food tray at the grease gun and set up the check valve, through the cooperation of the rising and the decline of check valve piston in the cavity to and the diameter of piston is greater than opening tip diameter, is less than the characteristics of the inside diameter of cavity, neither influences the grease gun and to the absorption of butter, has avoided the butter to sink and has caused the problem that forms the cavity in the grease gun yet. The utility model discloses simple structure, convenient operation has improved the efficiency of the injection butter of butter gun.
