Cutter with a slider that can be pushed from two directions and slider for the same

摘要

A cutter with a slider that can be pushed from two directions has a housing, a blade holder, a slider, and a blade. The slider is mounted moveably on the housing, is connected to the blade holder, and has an upper sliding element, a lower sliding element, and a resilient tab engaging at least one tooth formed on the blade holder. The upper sliding element has an L-shaped cross section to form a top wall and a side wall corresponding respectively to a top wall and a side wall of the housing. A guiding recess is defined by the side wall of the upper sliding element to slidably receive a portion of the side wall of the housing that forms an edge of a guiding channel. Accordingly, the cutter is convenient in use.

1. A cutter comprising:
a housing having:
a hollow body having a top wall and a side wall; anda guiding channel defined through the side wall of the body and having an edge; a blade holder disposed in the body of the housing and having multiple teeth; a slider mounted moveably on the housing, connected to the blade holder, and comprising:
an upper sliding element having:
an L-shaped cross section to form a top wall and a side wall corresponding respectively to the top wall and the side wall of the body of the housing;two protrusions; anda guiding recess defined by the side wall of the upper sliding element and slidably receiving a portion of the side wall of the body of the housing that forms the edge of the guiding channel;a lower sliding element combined with the upper sliding element and comprising a connecting base formed on and protruding from the lower sliding element at a side facing the upper sliding element;a resilient tab mounted on the lower sliding element and engaging at least one of the teeth on the blade holder; anda blade connected with the slider and mounted moveably in the blade holder, wherein:
the two protrusions abut a top surface of the connecting base on the lower sliding element;the resilient tab has two legs protruding from two ends of the resilient tab and extending out of the lower sliding element;each leg of the resilient tab has an engaging end extending out from the lower sliding element and engaging one of the multiple teeth on the blade holder;the two-protrusions of the upper sliding element abut respectively the engaging ends of the two legs of the resilient tabthe two protrusions are laterally formed on and protrude from the mounting segment of the positioning member; andeach protrusion has an inclined pushing surface defined in an end of the protrusion and abutting a corresponding one of the two legs of the resilient tab;each protrusion further has a pushing block formed on the protrusion at the end in which the inclined pushing surface is defined and faces the other protrusion; andthe pushing block of each protrusion has a length protruding from the upper sliding element toward the lower sliding element and that is larger than a length of each protrusion protruding from the upper sliding element toward the lower sliding element.
