The puncture device sealing mechanism solves the problem that an existing puncture device sealing mechanism is poor in sealing effect. The puncture device sealing mechanism comprises a puncture sleeve seat, an installing drum body and a sleeve seat cover body. A --shaped sealing cap is arranged in the puncture sleeve seat and comprises a cone drum body, the upper end of the cone drum body is provided with an annular positioning ring, one end of the annular positioning ring abuts against the outer edge of the end of the installing drum body, the other end of the annular positioning ring abuts against the sleeve seat cover body, the lower end of the cone drum body is provided with a cone-shaped necking-down drum body, the cone-shaped necking-down drum body is connected with a sealing drum body, the sealing drum body is provided with two recessed surfaces, protruded surfaces protruded inwards are formed on the inner sides of the recessed surfaces, and a rectangular table top is formed at the joint of the lower ends of the two recessed surfaces and provided with a strip-shaped slit. The puncture device sealing mechanism has the advantages that the puncture device sealing mechanism is simple in structure, convenient to assemble, high in stability and good in sealing effect, is installed firmly and does not leak air easily, and a sealing part is not turned up easily.
