can be applied on the original springs of the shock absorbers without changing the original equipments of the automobiles such enhancement offers extra supporting effect on the spring with present invention for an auxiliary support to reduce the deformation during compression and increase the coefficient of the spring the loading of the springs can increase and effectively improve the over leaning condition due to the deformation while the automobiles is turning the present invention can also apply to any equipment with springs such as spring beds elevators mechanical equipments to increase the hardness of the springs and reduce the deformation referring to fig1 and fig1 the ditch 13 for the fastener 30 can slant certain angle along the direction of the spring 20 or the stretching direction of the ditch 13 can pass the center of the spring 20 the spring 20 can have a binding effect along the compression direction when it is compressed for better fastening effect as shown in fig1 and fig2 the ditch 13 can be in multiple numbers for the fastener 30 to have multiple location choices referring to fig5 and fig6 the indentation ring 12 to stable the spring ring 21 can also locate on the top center of the body 10 and at least one through hole 14 on the other spring level is on the body 10 for fastener 30 to pass.
