在开辟新茶园,特别是修筑梯地时,需要一种测量水平线的工具,用以量出一条水平线(即在同一水平高度上的一条线)来,以保证梯坎质量。这里介绍一种制造容易、使用方便的两公尺水平跨尺。制作方法:用长2.1公尺的木板(或竹片)两根当跨脚,用长1.1公尺的木板(或竹片)一根当横板。然后在两个跨脚的一端10厘米处的中间各钻一个小孔,钉上螺丝。以跨脚上端的螺丝为起点,
When opening new tea farms, especially when building ladders, there is a need for a tool to measure horizontal lines to measure a horizontal line (ie, a line at the same level) to ensure the quality of the steps. Here to introduce a manufacturing easy, easy to use two meters horizontal feet. Production methods: 2.1 meters long wood (or bamboo) two when the cross, with a 1.1-meter-long plank (or bamboo) as a horizontal plate. Then drill a hole in the middle of each of the two legs 10 cm to nail the screw. To cross the top of the screw as a starting point,
