Support seat of an manual oil cylinder

Abstract

A support seat of a manual pump oil cylinder includes an oil cylinder, a handle and a transparent support seat. A distal end of the oil cylinder is locked by the transparent support seat. The oil cylinder is locked between the transparent support seat and the front seat by the fixing shaft. The handle is pivotally combined to the front seat. The transparent support seat is locked to a distal end of the supporting seat. Part or whole of the transparent support seat is made of transparent material. The transparent support seat is made with a middle hole and an annular trench. A cup-like nut and an annular oil seal are locked to a distal end of the oil cylinder. The transparent support seat is sealed and locked to a bottom of the oil cylinder. By the transparent support seat, the user can check the amount of oil directly.
