[0026] The coordinated operation of the limiting mechanism and the positioning structure enables the quick installation and removal of the dispensing head 5, avoiding the cumbersome and inefficient traditional manual replacement process. The precise snap-fit structure between the limiting rod 8 and the positioning groove 9 effectively prevents the dispensing head 5 from loosening during operation, ensuring the stability and consistency of the dispensing process. The device is also equipped with a sealing ring 10 and an outward protruding structure, which enhances the sealing performance of the glue guiding part, prevents glue leakage and air ingress, and improves the dispensing quality. In addition, the drive mechanism composed of the push ring 11, the pressure ring 15 and the return spring 12 can control the flexible extension and retraction of the limiting rod 8 and automatically reset it, improving the ease of operation.
[0027] The bottom of the guide tube 6 is connected to the bottom of the glue tube 3. The connecting tube 4 is coaxially sleeved on the outside of the guide tube 6 and a gap is formed between them. The dispensing head 5 is movably sleeved on the lower outer surface of the connecting tube 4. A sealing ring 10 is provided between the bottom surface of the guide tube 6 and the upper inner bottom surface of the dispensing head 5. The surface of the sealing ring 10 has protrusions protruding outward. The sealing ring 10 and its outward protruding structure can form a reliable sealing interface to prevent glue leakage or seepage.
[0028] A square hole 7 is provided on the lower outer surface of the connecting cylinder 4. A limiting mechanism is provided in the gap between the connecting cylinder 4 and the guide cylinder 6. The limiting mechanism is extended and retracted toward the square hole 7. A positioning groove 9 that cooperates with the limiting mechanism is provided on the upper inner wall of the dispensing head 5. A driving mechanism for driving the extension and retraction of the limiting mechanism is provided on the upper outer surface of the connecting cylinder 4.
[0029] The limiting mechanism includes a limiting rod 8, a support 17, and a support spring 16. The support 17 is fixed to the outer wall of the middle section of the guide tube 6. The middle part of the limiting rod 8 is rotatably connected to the support 17. The inner side of the lower end of the limiting rod 8 is connected to the outer wall of the guide tube 6 by the support spring 16. The outer wall of the lower end of the limiting rod 8 penetrates through the square hole 7. The outer side of the lower end of the limiting rod 8 has an outwardly extending boss. The side view of the boss is a right triangle, and the top surface of the boss is a right angle surface. The cross-sectional shape of the positioning groove 9 matches the shape of the boss of the limiting rod 8.
[0030] The driving mechanism includes a pressure ring 15 and a push ring 11. The pressure ring 15 is located in the gap between the connecting cylinder 4 and the guide cylinder 6 and above the limiting rod 8. The shape of the pressure ring 15 is a hollow frustum with a larger upper part and a smaller lower part. The lower end of the pressure ring 15 is located between the inner side of the upper end of the limiting rod 8 and the surface of the guide cylinder 6. The push ring 11 is slidably sleeved on the outer surface of the upper end of the connecting cylinder 4. A guide hole 13 is opened longitudinally on the outer surface of the upper end of the connecting cylinder 4. The inner wall of the push ring 11 penetrates through the guide hole 13 and is connected and fixed between it and the pressure ring 15. An annular groove 14 is opened on the outer surface of the upper end of the connecting cylinder 4. The push ring 11 is slidably connected up and down in the annular groove 14. A return spring 12 is connected between the bottom of the connecting cylinder 4 and the inner bottom surface of the annular groove 14.
[0031] The device, through a structure of a limiting mechanism, a positioning groove 9, and a driving mechanism, enables the dispensing head 5 to be quickly engaged and disengaged. The user only needs to push the push ring 11 to control the extension and retraction of the limiting rod 8 via the pressure ring 15. Specifically, the limiting rod 8 acts as a lever with the support 17 as the fulcrum. The boss of the limiting rod 8 retracts from the square hole 7 into the gap between the connecting cylinder 4 and the guide cylinder 6, thus enabling the disassembly or installation of the dispensing head 5 without tools, significantly improving replacement efficiency and ensuring the positioning stability of the dispensing head 5 after installation. The boss at the lower end of the limiting rod 8 precisely engages with the positioning groove 9 on the inner wall of the dispensing head 5, achieving mechanical limiting. The dispensing head 5 is designed with an anti-detachment function to prevent it from loosening or shifting during operation. A sealing ring 10 is added between the guide tube 6 and the dispensing head 5, and an outward protruding structure is designed on the surface of the sealing ring 10 to form a reliable sealing interface and prevent the glue from leaking or seeping out. Through the cooperation of the push ring 11 and the pressure ring 15, and the design of the return spring 12, the limit mechanism can automatically reset after release, improving the convenience and safety of operation. All moving structures are equipped with auxiliary structures such as supports 17, guide holes 13, and ring grooves 14, which enhance the guiding and durability of the mechanism and can work stably for a long time without being easily damaged.
