[0002] Moxibustion, as one of the traditional Chinese medicine therapies, has gained increasing popularity among consumers in recent years. With the booming development of the moxibustion industry, various moxibustion devices have appeared on the market, among which the suspended moxibustion cylinder is particularly popular due to its unique design. A suspended moxibustion cylinder typically consists of an outer paper sleeve, an inner support, and a bottom cloth piece. The outer paper sleeve provides protection, the inner support suspends the moxa stick, preventing it from directly contacting the inner wall of the paper sleeve, and the bottom cloth piece wraps around the bottom of the cylinder to prevent ash from falling during moxibustion. The bottom cloth piece is secured by a fixing sleeve fitted over the outer wall of the paper sleeve. A crucial step in the manufacturing process of the suspended moxibustion cylinder is placing the inner support, which holds the moxa stick, into the paper sleeve. This process requires the paper sleeve to be grasped and placed neatly, and then the inner support is suspended within it using other mechanisms. A positioning fixture is needed to ensure the neat placement of the paper sleeve. This fixture not only positions the paper sleeve but also allows for the successful installation of the cloth fixing sleeve after the inner support is placed. Designing a positioning fixture that meets these production requirements is a problem that urgently needs to be solved. Utility Model Content
