摘要： A cover for terminal screws of a receptacle, which has plug holes with a positive and a negative pole connected with terminal screws with a power line, is composed of a pivotal column, a locking hook and a cover case. The pivotal column is fixed on a sidewall of the receptacle, having a pivotal pin on its top and its bottom. The locking hook is fixed on the other side of the pivotal column on the sidewall. The cover case has a flat projection on the top and the bottom of its inner side, with each flat projection bored with a locking hole, and a locking bar with a rear opening provided at its other side. Then the pivotal pins may insert in the pivotal holes of the flat projections, and the locking bar is to lock with the locking hook, which is then to be confined in the opening, enabling the cover case to close stably on the terminal screws.

摘要： A halogen lampholder includes a base, a locking spring, two clipping members, two sliding members, a bottom cover, an outer shell and an outer ring. The base is assembled with the locking spring, the clipping members and the sliding members and then, with the bottom cover and the outer shell orderly. The base has a vertical plugging chamber for a fitting portion and two conducting teeth of a lamp to plug in. The locking spring clamps the fitting portion of the lamp. The clipping members connect with the conducting teeth. The sliding members are placed in the base to restrain the locking spring. The bottom cover restrains the locking spring and the clipping members. The outer shell covers the bottom cover, combined with an outer ring and a power-wire tube for a power wire to pass through and reach the clipping members.

摘要： A chain controlled lamp stand with multi-stage light modulation includes a control device to modulate brightness of a lamp. The control device consists of a chain-controlled switch and a light modulation circuit board controlled by the chain-controlled switch to modulate the brightness of the lamp. The chain-controlled switch in the lamp stand is combined with a rotatable disc, which can be actuated to rotate at its original location by a pull chain. The rotable disc is assembled thereon with a conducting metal contact strip, and the light modulation circuit board is provided with multi-stage connecting strips, which are able to change, and control voltage waveform. Thus, the metal contact strip is actuated to contact respectively with the multi-stage connecting strips to carry out multi-stage light modulation of the lamp stand.
