Abstract:
1. A clamp of an anti-vibration spring, comprising: a hollow pipe body with a first end, a second end, a length, and an axis along the length, having an elongated hole disposed on the hollow pipe body and parallel to the axis of the hollow pipe body; a first sheathing element and a second sheathing element, the first sheathing element being fixed at the first end of the hollow pipe body, the second sheathing element being mounted movably on the hollow pipe body, and each sheathing element having a connecting portion disposed at a position opposite of the elongated hole, and each connecting portion having a transversal slot disposed perpendicularly to the axis of the hollow pipe body, and each sheathing element having a first through hole disposed at the connecting portion and penetrated through the transversal slot; a moving element, accommodated inside the hollow pipe body, having a first internal screw hole and a connecting element passing through the elongated hole of the hollow pipe body, the connecting element being latched to the moving element, the second sheathing element sliding outside of the hollow pipe body and being fixed with the connecting element for linking the second sheathing element with the moving element; a screw rod passing into the hollow pipe body and screwing into the first internal screw hole of the moving element; a covering element, fixed at the second end of the hollow pipe body, an end of the screw rod passing through the covering element, and the second end of the hollow pipe body having a plurality of first insert holes, and the covering element having a plurality of second insert holes, each first insert hole aligning with one second insert hole and being secured with an insert pin for positioning the pipe body to the covering element; a driving element, fixed at the end of the screw rod that passes through the covering element; a first clamping disk mounted on the first sheathing element and a second clamping disk mounted on the second sheathing element, and each clamping disc having an insert portion to be inserted into each transversal slot of the sheathing elements, and each insert portion having a second through hole interconnected with the first through hole of each sheathing element, and each first through hole and each second through hole being secured with a positioning element and fixed to each corresponding sheathing element and each corresponding clamping disc respectively, and having a stop portion at each clamping disc for stopping the anti-vibration spring; wherein the moving element includes a sheathing slot disposed at a position corresponding to a side of the elongated hole of the pipe body, and the moving element having inwardly concave recessions disposed on first and second ends of the sheathing slot, and the connecting element being sheathed to the sheathing slot of the moving element, and first and second ends of the connecting element having a stop portion embedded into the inwardly concave recessions of the moving element, and the stop portions on the first and second ends of the connecting element having a second internal screw hole corresponding to the moving element, and the second sheathing element having two third through holes on a side of the elongated hole at an external periphery of the pipe body, and a locking element passing through each third through hole and securing the second internal screw hole of the connecting element.
