摘要： A transformer having a closed magnetic flux path includes at least one bobbin, at least one first winding, at least one second winding, and at least two magnetic cores. The first winding and the second winding are individually wound on the bobbin. The two magnetic cores include an I-shaped magnetic core and an E-shaped magnetic core piercing the inner part of the bobbin to form a closed magnetic flux path in the transformer. When one of the first windings is damaged, the other first winding still operates normally and is unaffected.

摘要： A pneumatic tool contains: a body, a drive unit, a piston element, at least one buffer, and a movable air tube. The body includes an intake head, a limiting sleeve, a switch, an air conduit, and a connection portion. The connection portion has a first guide element, a first guiding orifice, and the limiting sleeve has a shoulder. The drive unit includes a moving tube, a first segment, and a second segment. The moving tube has a protrusion, the second segment has a second guide element and a second guiding orifice. The moving tube has a coupling orifice and a cavity, and an air valve is defined between the cavity and the second guide element. One buffer is defined between the first guide element and the second guide element and includes a first through hole. The movable air tube includes an air inlet segment and an air outlet segment.
