[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-4 The utility model provides an embodiment: a metal head with strong sealing performance includes a sealing device 1 and a pipeline 2, the sealing device 1 is arranged at the end of the pipeline 2, the sealing device 1 includes a sealing head 3 and a clamping connection ring 10, the clamping connection ring 10 is fixedly connected to the sealing head 3, and the sealing head 3 is clamped and connected to the pipeline 2 through the clamping connection ring 10, so that the sealing head 3 and the clamping connection ring 10 can be conveniently clamped and connected to the end of the pipeline 2 to seal the pipeline 2, and the sealing gasket 9 can be fully squeezed between the clamping connection ring 10 and the outer wall gap of the pipeline 2 through the provided extrusion sealing frame 8, so as to play a role of full sealing, so that the sealing effect of the device is good.

[0019] A limit plate 5 is symmetrically fixedly installed in the middle of the side end of the sealing head 3, and a rotation adjustment threaded column 6 is rotatably clamped inside the limit plate 5. A screw-tightening bolt 4 is arranged on the outer side of the limit plate 5, and the middle part of the screw-tightening bolt 4 is fixedly connected to the end of the rotation adjustment threaded column 6.
