    • Disclosed is a device for cutting cloth or the like, including a lower substantially fixed blade and an upper movable blade pivotal with respect to the fixed blade. A handle extends at an acute angle with respect to the fixed blade and substantially transverse to the pivot axis of the blades. A lever is pivotally disposed within the handle, and the lever contacts a cam attached to the movable blade such that pivoting the lever effects pivoting of the movable blade. A trigger mechanism is disposed in the handle and manipulation of the trigger mechanism effects pivoting of the lever, and thus the movable blade.
    • 公开了一种用于切割布等的装置,包括下基本上固定的叶片和相对于固定叶片枢转的上可动刀片。 手柄相对于固定刀片以锐角延伸并且基本上横向于叶片的枢转轴线。 杠杆枢转地设置在手柄内,并且杆接触附接到可动刀片的凸轮,使得枢转杠杆实现可动刀片的枢转。 触发机构设置在手柄中,并且触发机构的操作实现了杠杆的枢转,从而实现了可动刀片。

    • The adjustable tape measure clip includes a strip of spring steel folded over to form a primary spring with opposing leaves, the inner leaf being adapted for attachment to the case of the tape measure. The inner leaf includes a secondary spring for adjusting the spring force of the primary spring on the leaves of the clip. A mounting screw, which mounts the spring clip onto the case of the tape measure, also engages the secondary spring on the inner leaf to adjust the secondary spring force on the primary spring. As the screw is rotated, the secondary spring varies the primary spring force and thus adjusts the free clip width between the leaves to either increase or decrease the gripping pressure of the clip on the user's apparel.
    • 可调节的卷尺夹具包括折叠的弹簧钢条,以形成具有相对叶片的主弹簧,内片适于附接到卷尺的外壳。 内叶包括用于调节夹子叶片上的主弹簧的弹簧力的次弹簧。 将弹簧夹安装到卷尺的壳体上的安装螺钉也与内叶上的次级弹簧接合,以调节主弹簧上的次弹簧力。 当螺钉旋转时,次级弹簧改变主弹簧力,从而调节叶片之间的自由夹宽度,以增加或减少夹子在使用者服装上的夹持压力。
