Description

CROSS-REFERENCE TO RELATED APPLICATIONS The application claims priority of Chinese patent application No. 202422687270.6 filed on Nov. 4, 2024, which is incorporated herein by reference in its entireties. TECHNICAL FIELD The present disclosure relates to the field of medical device technologies, and in particular, to a puncture lock catch connector and a glue-free and chemical-solvent-free infusion assembly. BACKGROUND Currently, a puncture head and a holding part are usually disposed in a puncture device body part of an infusion tube assembly. However, a holding part of an existing puncture device is mostly set as a cylindrical structure, so that in a case of unstable holding that may occur when a medical worker holds a puncture device, slippage is prone to occur. Once holding is unstable, the puncture head may accidentally stab the skin, causing potential safety risks to the medical worker when using the puncture device. Therefore, defects and deficiencies exist in the prior art, and need to be further improved and developed. SUMMARY In view of the foregoing shortcomings of the prior art, the purpose of the present disclosure is to provide a puncture lock catch connector and a glue-free and chemical-solvent-free infusion assembly, aiming at solving the problem that a puncture device in the prior art is prone to hold unstably to bring potential safety hazards to a medical worker.
