[0002] Bamboo products refer to products made from bamboo as processing raw materials, mostly daily necessities, such as bamboo baskets, bamboo sieves, bamboo strainers, scoops, bamboo steamers, cooking brooms, bamboo dustpans, bamboo buckets, bamboo rakes, baskets, bamboo shoulder poles, bamboo chopsticks, bamboo brooms, bamboo hats, bamboo plaques, bamboo backpacks, bamboo mats, bamboo mats, bamboo beds, bamboo stools, bamboo chairs, bamboo lounge chairs, chopping boards, mats, coasters, curtains, etc. In recent years, bamboo floors and bamboo furniture have become popular. There are also some higher-value folk crafts such as bamboo carvings. Some bamboo handicrafts require the bamboo strips to be heated and bent during processing to form a suitable bending angle to meet the processing and production needs of bamboo products.

[0003] After searching, a Chinese patent discloses a bending device for the production and processing of bamboo products (authorization announcement number CN213382048U), which includes a processing platform with a transmission groove in the center of the upper end face, a group of sliding seats slidably installed in the transmission groove of the processing platform, the sliding seats are installed in cooperation with a group of transmission screws, and the transmission screws are cooperated with the transmission mechanism, and two groups of first positioning seats are symmetrically installed on both sides of the upper end face of the processing platform, the first positioning seat is constructed in a truncated cone shape, and a group of first plug-in columns are provided at the top of the first positioning seat, and a group of detachable and replaceable abutment cylinders are arranged outside the first plug-in column, and a group of second positioning seats is arranged in the center of the upper end face of the sliding seat, the second positioning seat is constructed in a truncated cone shape, and a group of second plug-in columns are provided at the top of the second positioning seat, and a group of detachable and replaceable bending cylinders are arranged outside the second plug-in column.
