Revocable cushion block, including bottom plate 1, bottom plate 1 is made of steel plate or iron plate, still including upper plate 2, upper plate 2 also is made of steel plate or iron plate. One end of upper plate 2 is equipped with bending part 5, the other end of upper plate 2 is connected U-shaped spring piece 3, preferably, the length of bending part 5 accounts for one third to one fifth of the length of upper plate 2. U-shaped spring piece 3 is made of elastic steel sheet, as is known, U-shaped spring piece 3 is composed of a bending part and two plane parts.
[0012] One end of upper plate 2 and one end of bottom plate 1 are connected with the two plane parts of spring piece 3 respectively, and the one plane part of upper plate 2 and spring piece 3 is connected by screw 4, and the connection can be connected by more than two screws 4, can also be welded, can also be riveted, and the other plane part of bottom plate 1 and spring piece 3 is also connected by screw 4, and the same, the connection can be connected by more than two screws 4, can also be welded, can also be riveted.
[0013] Upper plate 2 is also provided with first threaded hole 7, and the first threaded hole 7 is located between the bending part 5 and the spring piece 3, preferably, the first threaded hole 7 is located at the middle between the bending line of the bending part 5 and the spring piece 3, and those skilled in the art should know that if the plate member is provided with a thread, the thickness of the plate member should not be too thin---this is the common knowledge in the art.
[0014] A first screw 8 that is adapted to the first threaded hole 7 is arranged in the first threaded hole 7, one end of the first screw 8 abuts against the upper surface of the bottom plate 1, the upper surface of the bottom plate 1 is opposite to the lower surface of the upper plate 2, and rotating the first screw 8 can adjust the height of the bending part 5 from the bottom plate 1, because rotating the first screw 8 changes the position of the first threaded hole 7, thereby changing the included angle of the upper plate 2 and the bottom plate 1, the other end of the first screw 8 is fixedly connected with a metal ring 9, the metal ring 9 and the first screw 8 are located in the same plane, and the metal ring 9 can be used to apply torque, for example, through a metal rod, to provide greater torque.
