[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model adds an outer cover body to the male die head and the female die head so that both the die heads are embedded in the cover body, so that the user cannot directly touch the die head, thereby preventing the user from accidentally touching the die head after the die head is heated up, causing personal safety. Through the arrangement of the outer cover plate and the through hole, the user can insert a PE pipe matching the die head at the through hole, and the PE pipe at the male die head can be restricted by the limit plate, so that the end of the PE pipe is restricted between the limit plate and the male die head in the inserted state. At the same time, the limit plate is arranged outside the male die head, which can play a blocking and restricting effect, making it more difficult for the operator to directly touch the male die head, thereby improving safety. The above structure blocks and restricts the die head without affecting the plug-in and pull-out combination of the PE pipe and the die head, which can effectively improve the safety of the heater when in use.
