[0061] The sliding limit function can be achieved by the slide rail 51 and the slider 52, and the I-shaped slide rail 51 has a better limiting function.

[0062] In this embodiment, the heat-melting part includes,

[0063] Several fixing posts 71 are fixed at one end to the lower surface of the fixing plate 6; the fixing posts 71 are perpendicular to the fixing plate 6.

[0064] The heating block 72 is fixedly connected to the other end of a plurality of fixed posts 71; the lower surface of the heating block 72 is provided with a plurality of first threaded holes 721;

[0065] Heating element 73 is disposed inside heating block 72;
