[0002] Bamboo is a fast-growing grass plant with strong regeneration ability. It has more than one thousand different species and is widely distributed in tropical and subtropical regions around the world. Its stems are solid and elastic. It has been developed and utilized by humans since ancient times and made into various bamboo products, from daily necessities such as baskets, chopsticks, and furniture to building materials, and even modern bamboo floors and bamboo fiber fabrics. Bamboo products have demonstrated their extremely high practical value and environmental protection characteristics. Bamboo has a short growth cycle and does not require a large amount of fertilizers and pesticides, so it has little impact on the environment. It is a green resource for sustainable development.

[0009] As an improvement, when the hydraulic rod is shortened and the output shaft of the stepper motor is at its longest, the lowermost end of the output shaft of the stepper motor exceeds the lowermost end of the cylinder shaft of the lower cylinder;

[0010] As an improvement, when the bottom surface of the truncated cone fits the middle of the T-shaped hole, one side of the scraper fits the output shaft of the stepper motor.

[0011] Beneficial effects of the utility model:
