[0028] Among them, the unlocking cone block 10 is through and slidably connected on the conductive slide rod 8 and is used for pushing the triangular lock block 18 to realize the unlocking of the heating ring 5. The placing groove 11 is used for accommodating the compressed first spring 12. The first spring 12 provides the reset elastic force for the unlocking cone block 10.

[0029] In the embodiment, the second spring 13 is fixedly installed at the bottom of the connecting hole 3, the conductive sheet 14 is fixedly connected to the top of the second spring 13, the conductive sheet 14 is electrically connected to the conductive cone block 9, the conductive groove 15 is arranged in the sidewall of the bottom of the connecting hole 3, the conductive rod 16 is fixedly installed on the side of the conductive sheet 14 and is slidably connected to the conductive groove 15, and the inner walls of the pair of conductive grooves 15 are respectively provided with positive and negative poles.

[0030] The second spring 13 keeps the conductive sheet 14 in close contact with the conductive cone block 9, and provides elastic force for the conductive cone block 9 to be popped out when being unlocked. The conductive sheet 14 transmits current by cooperating with the conductive groove 15 through the conductive rod 16. The conductive rod 16 is fixedly installed on the side of the conductive sheet 14 and slides in the conductive groove 15, thereby realizing current transmission.

[0031] In the embodiment, the lock hole 17 is arranged in the sidewall of the connecting hole 3 above the conductive groove 15, the triangular lock block 18 is slidably connected in the lock hole 17, the triangular lock block 18 clamps the conductive cone block 9, and the third spring 19 is fixedly connected between the triangular lock block 18 and the inner side end of the lock hole 17.
