When the rigidity of the first rubber layer is increased, the steps are the same as those when the rigidity of the rubber layer is reduced, and the adjusting direction is opposite. The specific adjustment steps are as follows:
1) inserting the height measuring pin 5 into the height measuring pin through hole 14 of the upper cover 3 to measure the ascending distance L of the power assembly;
2) rotating the first inner framework 1 to enable the first inner framework 1 to descend until the upper plane of the power assembly upper support 18 is flush with the upper plane of the height measuring pin 5, adjusting the total height and the lower limiting distance B, and pulling out the height measuring pin;
3) the locking pin 4 is taken out along the first through hole 11 of the power assembly upper support 18, the upper cover 3 is rotated to enable the locking pin to ascend L height, the locking pin 4 can be checked after adjustment, namely when the upper plane of the upper cover 3 contacts the tail end of the locking pin 4, the scale position of the letter indication D on the locking pin 4 is flush with the upper plane of the power assembly upper support 18, and the adjustment of the limiting distance is completed.
