Abstract: A can opener has an elongated rectangular base plate on which a can support box is centrally mounted. Four right angle corner rails extend upwardly from corners of the support box. The rails are connected by side support braces which form a square around midpoints of the corner rails. A top guide plate is secured to upper ends of the corner rails. A pair of slide bearings in the top guide plate mount a pair of slide rods. A transversely extending cross bar is secured to upper ends of the slide rods. The cross bar has a handle grip at each end. A blade mounting plate is secured to the lower ends of the slide rods. Four triangular tempered steel blades are secured to the side edges of the blade mounting plate. The blades extend perpendicularly downwardly from the blade mounting plate. L-shaped side support rods extend from opposite sides of the base plate to the side support braces. A pair of coiled springs extend between the transverse cross bar and the side support rods. In use, a user stands on the base plate and raises the transverse cross bar and attached blade assembly. By placing a welding electrode can in the can support box and releasing the cross bar handles, the blades will be snapped downwardly by the springs to sever the top from the welding rod can. A rubber block on the top guide plate cushions the cross bar.

Abstract translation: 罐头开启器具有细长的矩形底板，罐支撑箱在其上居中安装。 四个直角角钢轨从支撑箱的角落向上延伸。 导轨通过侧支撑支架连接，侧支撑支架围绕角钢轨的中点形成一个方形。 顶部导板固定在角钢轨的上端。 顶部导轨中的一对滑动轴承安装了一对滑杆。 横向延伸的横杆被固定到滑杆的上端。 横杆在每一端都有手柄。 刀片安装板固定在滑杆的下端。 四个三角回火钢刀片固定在刀片安装板的侧边缘。 叶片从叶片安装板垂直向下延伸。 L形侧支撑杆从基板的相对侧延伸到侧支撑支架。 一对螺旋弹簧在横向横杆和侧支撑杆之间延伸。 在使用中，使用者站立在底板上并升高横向横杆和附接的叶片组件。 通过将焊接电极罐放置在罐支撑箱中并释放横杆手柄，刀片将被弹簧向下卡扣，以从焊条罐上切下顶部。 顶部导向板上的橡胶块垫紧横杆。
