Abstract:
The present invention relates to a mechanical pencil, and more particularly, a mechanical pencil capable of preventing the damage or deformation of a lead tube, which is a part for supporting and fixing a lead, due to the external impact. The mechanical pencil of the present invention comprises: a housing configuring a body; a lead tube installed inside the housing to be able to move in a longitudinal direction and having a catching protrusion that protrudes outwardly; an elastic support plate installed on an inner wall of the housing and connected to the catching protrusion of the lead tube, wherein the elastic support plate suppresses the movement of the lead tube in a backward direction when a great force is not applied, and allows the movement of the lead tube by being transformed when a great force is applied; a cap coupled with a rear end of the lead tube to allow the lead tube to rate; and a spring for connecting the catching protrusion to the elastic support plate by applying a force to the lead tube backwardly.
Abstract:
The present invention relates to a vacuum chamber structure. Especially, the vacuum chamber structure comprises a bottom panel (100) formed on a bottom surface; first plates (110) parallel to the upper part of the bottom panel (100); and second plates (120) inserted between the first plates (110) and formed on the upper part of the bottom panel (100). Cost performance is improved by reducing the weight of the vacuum chamber and the rigidity of structure is improved. Therefore, marketability is improved by minimizing variation according to pressure.
