在施工现场,对拔楔是木工支模板常用的支撑加固材料。为保证安全,在电锯旁常用长度300毫米以上的木材锯制而成。这不仅浪费了木材,而且锯伤指掌也时有发生。经多年实践,我们发明了一种保护叉,取得令人满意的效果。一、保护叉制作取一块550毫米×80毫米×30毫米的木板,一端锯成缺口状,另一端削成宽50毫米的把柄,将柄 In the construction site, the pull wedge is a common support reinforcement material for the woodworking support plate. In order to ensure safety, it is often sawed by wood that is longer than 300 mm. This is not only a waste of wood, but also the occurrence of saw injuries. After many years of practice, we invented a protective fork to achieve satisfactory results. First, protect the fork to take a 550 mm × 80 mm × 30 mm board, one end sawed into a notch, the other end cut into a 50 mm wide handle, the handle
