发明名称 Silent dent puller
摘要 A dent puller tool has a bracing frame which straddles a small dent, which may even be curved. An exteriorly threaded turn rod has a puller tip for penetrating a drilled hole and pulling out the dent. The tool includes a hollow, tubular guide shaft, threadedly adjustable longitudinally in the frame, and the turn rod is freely movable therein. The guide shaft is adjusted to locate its lower rim as a stop for the puller tip at the desired level when a winged nut, threaded on the rod, is turned against the upper rim of the guide shaft. A separable elongated frame-like base extension receives the base of the frame for straddling large dents and serving as a pull stop therefor.
