Establish one section sheath at toughness cover outside cover, the free end edge of sheath compresses tightly and with the free end edge welded fastening of right guide arm towards the axis direction, a plurality of oil grooves are seted up at the other end edge of sheath, utilize the flaring machine to right guide arm edge flaring, make the flaring portion that right guide arm edge formed the horn mouth form, the flaring portion forms the section and is curved structure, at this moment, because the one end of sheath is fixed with right guide arm, the other end is not fixed, at the flaring in-process, the sheath can form the round platform shape, form between sheath and the right guide arm and hold the chamber, the elastic sleeve, oil absorption cotton and toughness cover are located and hold the intracavity, a breach groove is seted up in the minimum position of flaring portion. When the right guide rod and the left guide rod are close to each other, lubricating oil on the outer wall of the right guide rod can move inwards along with the right guide rod and is coated on the inner wall of the first fixing sleeve, one part of the lubricating oil on the inner wall of the first fixing sleeve is adhered on the first fixing sleeve, and the other part of the lubricating oil forms oil drops and drops on the lowest point position of the inner wall of the first fixing sleeve, the right guide rod and the left guide rod. When keeping away from each other right guide arm and left guide arm, because the edge of flaring portion and the laminating of first fixed cover inner wall, the flaring portion can scrape away the lubricating oil on the first fixed cover inner wall towards right guide arm direction, forms oil to drip and drops and get back to on the right guide arm lateral wall, and is close to towards the fixed cover of third when right guide arm, and the fixed cover of third can promote part lubricating oil towards flaring portion direction, and lubricating oil gets into along going out the oil groove and holds the intracavity and be adsorbed by the oil absorption cotton. When the flaring portion reaches the third fixing sleeve, the edge of the third fixing sleeve limits the sheath and extrudes the sheath, the pressure inside the accommodating cavity is increased after the sheath is pressed, the oil absorption cotton is pressed to discharge the adsorbed lubricating oil along the oil outlet groove, and the right guide rod is continuously lubricated. And in the moving process of the right guide rod, the notch formed at the notch groove can not exert thrust force to scrape off lubricating oil at the lowest point of the inner wall of the first fixed sleeve, so that the lubricating oil stays at the lowest point of the first fixed ceramic. When the left guide rod and the right guide rod are close to each other, the lubricating oil left at the lowest point of the first fixing sleeve returns to the accommodating cavity along the notch groove again and is absorbed and stored by the oil absorption cotton. When the left guide rod is contacted with the right guide rod, when the axis of the left guide rod is inclined, the flaring part can guide the end part of the left guide rod, so that the left guide rod can enter the inside of the right guide rod along the guide of the flaring part. When the shaft line of the left guide rod extrudes the flaring part obliquely, the flaring part reaches the axial pressure, the oil absorption cotton is compressed after the containing cavity is compressed, the lubricating oil in the oil absorption cotton is exhausted along the oil outlet groove after being extruded, and the right guide rod, the third fixed sleeve, the left guide rod and the second fixed sleeve are lubricated.

Thus, the lightweight clip of the present invention has the following advantages: the synchronous slip of two splint about the slip cover pole group can be realized, improves the synchronism, and the mount is whole to be moved valves, slide rail, slip cover pole subassembly and splint and to be gathered, reduces whole weight, realizes the lightweight of whole house.
