[0021] This utility model embodiment provides a syringe with an exogenous ring, such as Figure 1-5 As shown, the device includes a syringe body 1, with multiple inserts 2 fixedly installed in a ring at equal intervals around the syringe body 1. An inner ring 3 overlaps the top of the syringe body 1, and an outer ring 4 is fitted around the outer side of the inner ring 3. The outer ring 4 is fixedly installed to the circular knitting machine bracket.

[0022] The outer ring 4 has a groove at its top, within which a needle plate 5 slides. A slot 31 is formed between the inner ring 3 and the syringe body 1. The slot 31 has a rectangular cross-section, and the end of the needle plate 5 has an extension that fits into the slot 31. The needle plate 5 and the extension are integrally formed. The slot 31 is positioned relative to the mouthpiece.

[0023] Insert 2 is positioned between the outer sacrocolporate ring 4 and the inner sacrocolporate ring 3. The bottom of the inner wall of the groove of the outer sacrocolporate ring 4 is flush with the top of the syringe body 1, and the top of insert 2 is flush with the top of the syringe body 1. During movement, the sacrocolporate 5 contacts the top of insert 2. This arrangement causes friction between insert 2 and sacrocolporate 5, thereby reducing the impact force of sacrocolporate 5 on the inner sacrocolporate ring 3 and extending its lifespan.

[0024] A curled elastic sheet 21 is welded to the top of the insert 2. The curved surface of the elastic sheet 21 can contact the bottom of the sunke 5. Friction grooves 22 are formed on the curved surface of the elastic sheet 21. When the sunke 5 moves, it contacts the elastic sheet 21, causing the elastic sheet 21 to curl and generate a reaction force. The friction grooves increase the friction force, further reducing the speed at which the sunke 5 is inserted into the slot 31.

[0025] A rubber ring 32 is fitted inside the slot 31. When the extension of the end of the sinker 5 extends into the slot 31, the rubber ring 32 contacts the extension, thus providing a cushioning effect.

[0026] A pressure sensing unit 11 is fixedly installed inside the syringe body 1, and the top of the pressure sensing unit 11 is fixedly installed to the bottom of the leishenck ring 3. The weight of the leishenck ring 3 is measured by the pressure sensing unit 11. If the measured pressure value is less than the preset value, it indicates that the leishenck ring 3 is severely worn and needs to be replaced.

[0027] By changing the insert 2, the point of force applied to the initial impact of the sinew 5 is altered, making it suitable for syringes used with any sinew ring.

[0028] Because the top of insert 2 just touches the bottom of sinch 5, it forms a two-way support for sinch 5, reducing the friction between sinch 5 and inner sinch ring 3, making it less prone to wear, protecting the inner sinch ring, and extending the life of the inner sinch ring 3.

[0029] In summary, this syringe with an outer sinusoidal ring consists of a syringe body 1, an insert 2, an inner sinusoidal ring 3, an outer sinusoidal ring 4, and a sinusoidal plate 5. The insert 2 contacts the sinusoidal plate 5 at its top, thereby altering the initial stress point at the end of the sinusoidal plate. The elastic plate 21 and rubber ring 32 work together to enhance the cushioning effect and extend the lifespan of the inner sinusoidal ring 3. Excessive friction and impact between the sinusoidal plate 5 and the inner sinusoidal ring 3 are avoided, further reducing wear and tear on the inner sinusoidal ring 3. Furthermore, a pressure sensing unit 11 detects the weight of the inner sinusoidal ring 3, providing real-time monitoring.
