The invention provides a novel hot pressing head with adjustable parallelism, overcomes the shortcomings of a conventional hot pressing head such as inconvenience in the adjustment of parallelism, poor stability and low heat insulation capability in high-frequency pressing and sticking, and realizes the manufacturing of high-precision hot pressing heads under the general machining precision conditions so as to effectively reduce the machining cost and be helpful for improving the overall rigidity of the pressing head and the production speed of equipment. The structure of the novel hot pressing head comprises an X-axis rotating seat 1, a Y-axis rotating seat 9, a heat insulating connecting plate 5, a rotating shaft 2, an X-axis left tensioning block 3, an X-axis right tensioning block 10, an X-axis adjusting seat 12, a Y-axis tensioning block 7, a Y-axis adjusting seat 13, a small heat insulating plate 4, big heat insulating plates 6 and 14, a radiating column 8, a pressing head seat 15, tensioning screws 11, top thread 16 and a copper bush 17. By adjusting the two tensioning screws 11 up and down, the pressing head seat 15 can be adjusted to rotate around an X axis and a Y axis.
