Arc-shaped wall plastering tool capable of accurately adjusting radian
The invention discloses an arc-shaped wall plastering tool capable of accurately adjusting the radian. The arc-shaped wall plastering tool solves the problem of how to accurately adjust the plastering radian of a plastering tool. A thin spring steel plate is made into an arch-shaped patter, pull rods capable of changing the radian of the arch-shaped patter are welded to the inner side faces of the two ends of the arch-shaped patter respectively, and racks are welded to the inner side ends of the pull rods respectively; a box-shaped barrel is manufactured, a movable center shaft is arranged in the center of the box-shaped barrel, a gear is fixedly connected to the center shaft in the box-shaped barrel, the inner side ends of the two racks movably penetrate into the box-shaped barrel, and then are engaged with the gear fixedly connected to the center shaft in the box-shaped barrel; a ratchet wheel is fixedly connected to the central shaft which upwards penetrates out of the outer side of the upper top surface of the box-shaped barrel, a pawl and a pawl tension spring are arranged on the upper top surface of the box-shaped barrel, and the pawl is connected with the ratchet wheel in an abutting mode; and the lower end of the arch-shaped patter is connected with a plastic scraping plate for improving the plastering smoothness. The radian of trowel is convenient to adjust.
本发明公开了一种可精准调节弧度的弧形墙面抹灰工具，解决了如何精准调整抹灰工具的抹灰弧度的问题。用薄的弹簧钢板制作成弓形抹板，在弓形抹板的两端内侧面上分别焊接一根可改变弓形抹板弧度的拉杆，在拉杆的内侧端各焊接一个齿条；制作一个箱形筒体，在箱形筒体中央处设置一根活动中心轴，在箱形筒体的筒内中心轴上固定连接齿轮，上述两齿条的内侧端活动穿入箱形筒体内后，与筒内中心轴上固定连接的齿轮啮合在一起；在向上穿出到箱形筒体上顶面外侧的中心轴上固定连接一个棘轮，在箱形筒体上顶面上设置有棘爪和棘爪拉紧弹簧，棘爪与棘轮顶接在一起；在弓形抹板下端连接有提高抹灰光洁度的塑料刮板。方便调节抹子的弧度。
