近年来,随着电网容量不断增大,断路器的使用数量也不断增多。针对开关使用橡胶垫数量比较多、规格大小不一这一特点,我们制成了电动割园刀,以取代笨重的手式割园刀。其结构如图1所示。其中:1.割柄:利用φ8钻柄尾段,φ8×60毫米。2.刀架板:用5毫米钢板制成刻度尺,260×35×5如图2。3.刀架;采用缝纫机针架。4.固定螺丝:M_5元宝式。5.接至台钻6.钢针割园刀:钢针 In recent years, with the increasing capacity of the power grid, the use of circuit breakers has also been increasing. For the switch to use more rubber pads, different sizes of this feature, we made the electric cut garden knife to replace the bulky hand-cut garden knife. The structure shown in Figure 1. Of which: 1. Clasp: use φ8 drill shank tail section, φ8 × 60 mm. 2. Knife plate: made of 5 mm steel scale, 260 × 35 × 5 as shown in Figure 2.3. Turret; sewing machine needle holder. 4 screws: M_5 ingot-style. 5. Connected to the bench drill 6. Steel needle cutting Park knife: steel needle
