This patent tool has the following advantages:

1, cushion blocking employing material is elastic caoutchouc, has good compression and the performance of upspringing, and can work the effect that separates vibration, extends the service life of radiator.

2, washbowl can strengthen the area of contact of radiator and bracket component, to ensure the stability of radiator.

3, there is the feature of simple in structure, easy accessibility, dependable performance.
