The invention relates to a sport facility, in particular to a claw anchoring barbell which is constructed by snap spring edges, a spring, a sliding sleeve, a cartridge barrel, a weight tray, fixing rings, an anti-sliding sleeve, a grab handle and a deformed seam. The grab handle is of column shape, two ends of the grab handle are respectively provided with a snap spring edge protruding out of theside of the grab handle. The grab handle is provided with two annular fixing rings integrated with the grab handle, and the cartridge barrel sheathed at the grab handle and in dynamic match relation with the grab handle. The weight tray is sheathed on the grab handle and the difference between the central hole of the weight tray and the radius of the grab handle is greater than the thickness of the cartridge barrel. The cartridge barrel is positioned at the outer end of the weight tray, and the spring is sheathed on the grab handle between the cartridge barrel and the snap spring edges. The cartridge barrel is composed of the outer cylinder and the inner cone face thereof. The invention eliminates the potential safety hazard caused by slipping of the weight tray in the motion of the barbell.
