It is fixed by jackscrew one with needle leading portion is listened；It is described to listen the separate one end for listening needle leading portion in needle middle section by articulated shaft two and listen needle back segment
Hingedly, listen and be fixed with fixed baffle two on needle middle section, jackscrew two is installed on fixed baffle two, listen needle middle section by jackscrew two with
Needle back segment is listened to fix；It is described to listen needle back segment far from listening the one end in needle middle section to be fixed with auscultation head, radio reception cover is provided on the outside of auscultation head,
Radio reception cover, which is fixed on, to be listened on needle back segment.
Further, described to listen needle leading portion, listen needle middle section, the material of needle back segment and auscultation head is listened to be stainless steel or copper.
The beneficial effects of the utility model are: structure is simple, folding storage is easy to carry, is hardly damaged.
Detailed description of the invention
Fig. 1 is the collapsible structural schematic diagram for listening needle of one kind described in the utility model；
Fig. 2 is the partial enlarged view at Figure 1A；
Fig. 3 is the partial enlarged view at Figure 1B；
In figure, 1, listen needle leading portion；2, needle middle section is listened；3, needle back segment is listened；4, radio reception cover；5, auscultation head；6, articulated shaft one；7, solid
Determine baffle one；8, jackscrew one；9, articulated shaft two；10, fixed baffle two；11, jackscrew two.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
It clearly and completely describes, as shown in Figure 1-3, one kind is collapsible to listen needle, including listens needle leading portion 1, listens needle middle section 2 and listen needle back segment
3, needle leading portion 1 is listened by articulated shaft 1 and listens needle middle section 2 hinged, is listened and is fixed with fixed baffle 1, fixed baffle on needle middle section 2
Jackscrew 1 is installed on one 7, listen needle middle section 2 by jackscrew 1 and listens needle leading portion 1 fixed；Listen needle middle section 2 is separate to listen needle leading portion 1
One end by articulated shaft 29 and listen needle back segment 3 hinged, listen and be fixed with fixed baffle 2 10 on needle middle section 2, fixed baffle 2 10
On jackscrew 2 11 is installed, listen needle middle section 2 by jackscrew 2 11 and listen needle back segment 3 fixed；Listen needle back segment 3 far from listening needle middle section
2 one end is fixed with auscultation head 5, and the outside of auscultation head 5 is provided with radio reception cover 4, and radio reception cover 4, which is fixed on, to be listened on needle back segment 3；Listen needle leading portion
1, it listens needle middle section 2, the material of needle back segment 3 and auscultation head 5 is listened to be stainless steel or copper.
For the present apparatus by repeatedly improvement, it is best that folding listens needle to be divided into three-stage effect, it is convenient for collecting after can easily folding and
It carries；Folding listens the articulated manner of needle identical as the articulated manner of jackknife, and the articulated manner of jackknife belongs to the prior art, In
This is not described in detail；Folding is fixed after listening needle to be unfolded by jackscrew, makes that needle is listened to be able to maintain straight state.
Above-mentioned technical proposal only embodies the optimal technical scheme of technical solutions of the utility model, the technology of the art
Personnel embody the principles of the present invention to some variations that some of them part may be made, and belong to the utility model
Protection scope within.
