To sum up, the beneficial effects of the utility model are that:

1. the utility model discloses a mode that the rotation lead screw drove last compression support and lower compression support opposite direction movement and motion dorsad, play the effect of compression to coil spring, through the setting of rotating the handle, make things convenient for staff's operation, thereby it is very inconvenient to have solved current suspension spring's dismantlement, the extracting tool is bulky, high use cost, it wastes time and energy to use, still there is certain dangerous problem simultaneously, and convenient operation adopts the mode that all sets up the compressor in the coil spring both sides, and the compressive force is improved, and the safety in utilization has been guaranteed.

2. The utility model discloses a set up the blind hole at the lead screw lower extreme, rotate the mode that the handle passes through the connecting rod and connects the lead screw for can be according to the length of in-service use demand regulation connecting rod, thereby make the integrated device use more convenient.

3. The utility model discloses a middle section that states the lead screw is equipped with smooth portion, the cover is equipped with swivel bearing in the smooth portion, one side that swivel bearing is close to last compression support and lower compression support is equipped with two parallel arrangement and the middle baffle that leaves the clearance, goes up the mode that compression support and lower compression support all press from both sides and establish between two sets of baffles for when the lead screw rotates, it is rotatory that the lead screw can not be followed to all the other subassemblies, thereby has improved the compression and the speed of relaxing to the spring, has improved work efficiency.

4. The utility model discloses a setting of spacing ring has restricted the maximum stroke of last compression branch and lower compression branch, has improved the security of integrated device.
