Embodiment
As shown in figure 1, microwave melt needle includes：Needle point body 1, shank 2, microwave coaxial connector 6, handle 7, water inlet pipe 8,
Outlet pipe 9, through there is a microwave coaxial cable 10 in shank 2, one end of the microwave coaxial cable 10 is connected with microwave coaxial
Device 6 is connected, and the water inlet pipe 8 and outlet pipe 9 are fixed on the handle 7.The first embodiment as shown in Figure 2,3, its
In, the material of needle point body 1 is ceramic body, and needle point body 1 is internally formed hollow space, in the needle tip wall of needle point body end section 3
Thinning, the needle tip wall of needle point body end section 3 is formed and is recessed due to the different of thickness from the needle tip wall of the fore-end of needle point body 1
4, the end section 3 that shank 2 prolongs the needle point body is inserted, and the front end of shank 2 is arrived at depression 4, the inwall of shank 2 and needle point body tail end
Gap filling seccotine 301 between dividing on the outside of 3 needle tip wall is bonded.The other end insertion of the microwave coaxial cable 10
Gap between on the inside of the hollow space of needle point body 1, the outer wall of microwave coaxial cable 10 and the needle tip wall of needle point body end section 3
Also filling seccotine 301 is bonded.One or more is opened in the needle tip wall of needle point body end section 3 and runs through whole needle point body
The through hole 5 of the needle tip wall of end section 3, when needle point body end section 3 and shank 2 and microwave coaxial cable 10 are bonded,
One or more through holes 5 are also stuffed entirely with by seccotine 301.Wherein, the material of shank 2 can be stainless steel.
In second of embodiment, remaining part in addition to needle point body 1 of microwave melt needle and assembling bonding
Mode is identical with the first embodiment, will not be repeated here.The difference of second of embodiment and the first embodiment
It is only that, the structure of needle point body 1 is made up of T-shaped needle body 11 and the two parts of ceramic body 12, as shown in Figure 4.Wherein, T-shaped needle body 11
Material be high duty metal, the inner wire of the T-shaped needle body 11 and the microwave coaxial cable 10 of the hollow space of insertion needle point body 1
It is connected.
Among actual operation, run through whole pin due to one or more in the needle tip wall of needle point body end section 3 be present
The through hole 5 of the needle tip wall of sharp body end section 3, between making on the outside of the needle tip wall of the inwall of shank 2 and needle point body end section 3
The outer wall and needle point body end section of seccotine 301, the seccotine 301 being filled among through hole 5 and microwave coaxial cable 10
