The scheme that the utility model solve the technical problem is:
A kind of probe of the dust detection instrument with coupling sleeve, comprise probe cassette and metal bar, described metal bar is located in coupling sleeve, the upper end of coupling sleeve, the lower end that the other end stretches out coupling sleeve are stretched out in metal bar one end, the part that metal bar stretches out the lower end of coupling sleeve is induction part, at least be coated with Teflon material layer on induction part surface, coupling sleeve top is screwed onto in probe cassette, and coupling sleeve bottom forms external thread.
Described metal bar sleeve is also placed in coupling sleeve.
The top of coupling sleeve is screwed onto in the screw forming on the base plate of box body of probe cassette, and the top of metal bar is stretched in box body, forms side screw on the sidewall of box body.
Described Teflon material layer is coated on whole metal bar surface.
The middle part of described coupling sleeve is six cylinders.
Described probe cassette structure is, lid covers on box body, and the screw rod of set bolt is through lid and be screwed onto in box body.
The top of described coupling sleeve is that upper spiro union portion, bottom are lower spiro union portion, the length of upper spiro union portion and lower spiro union portion equal in length.
Described upper spiro union portion is screwed onto in the screw forming on the base plate of box body of probe cassette, and the outer wall of lower spiro union portion forms external thread.
Outstanding effect of the present utility model is:
Compared with prior art, the bottom of its coupling sleeve can directly be installed on the equipment installation position with screw, whole probe can be directly installed on the equipment installation position with screw, it is simple in structure, and coupling sleeve is screwed onto on mounting box or mount pad, it can conveniently unload and install from mounting box or mount pad, and namely metal bar can be arranged on mounting box or mount pad easily, also can be intact unload from mounting box or mount pad; Meanwhile, Teflon material layer is coated on metal bar, makes it have high temperature resistant, high pressure resistant, corrosion-resistant, sealing and the stable feature of translation data.

Embodiment:
Embodiment, see as shown in Fig. 1 to 5, a kind of probe of the dust detection instrument with coupling sleeve, comprise probe cassette 1 and metal bar 2, described metal bar 2 is located in coupling sleeve 3, and the lower end that upper end, the other end of coupling sleeve 3 stretch out coupling sleeve 3 is stretched out in metal bar 2 one end, the part that metal bar 2 stretches out the lower end of coupling sleeve 3 is induction part, at least be coated with Teflon material layer 4 on induction part surface, coupling sleeve 3 tops are screwed onto in probe cassette 1, and coupling sleeve 3 bottoms form external thread 31.
Described metal bar 2 sleeves are also placed in coupling sleeve 3.
The top of coupling sleeve 3 is screwed onto in the screw 112 forming on the base plate 111 of box body 11 of probe cassette 1, and the top of metal bar 2 is stretched in box body 11, forms side screw 113 on the sidewall of box body 11.
Described Teflon material layer 4 is coated on whole metal bar 2 surfaces.
