The invention relates to the technical field of glass door floor spring, in particular to a large-angle swing floor spring. The floor spring comprises a door frame and a glass door. After the glass door is opened 180 degrees, due to the inertia of the swing of the glass door, the glass door can hit the door frame or a wall, causing damage to the glass door. The floor spring designs a buffer block.The buffer block is used to offset the inertial force of the glass door to prevent the glass door from knocking down the door frame or the wall, causing damage to the glass door. By adjusting the length of a damping screw rod in a first guide groove and a second guide groove, the resistance in the sliding process of two pistons is determined, that is, by adjusting the damping screw rod, the resistance of the rotation of a cam can be adjusted, and then the resistance of the glass door in the process of opening and closing can be adjusted. The nested motion of a first sliding rod and a second sliding rod is designed, on the one hand, the installation space is reduced, and on the other hand, the motion stroke of a first return spring and a second return spring is reduced.
