This utility model is made of two ear clip listening tubes, threeway sebific duct, auscultation head, inventive point is to insert an arc-shaped spring piece in the threeway sebific duct, the spring leaf two ends is the opening ring-type, and it is screw-like that two ear clips are listened pipe end, and insert in the split ring of spring leaf two ends the screw-like termination.

Accompanying drawing 1 is faced part sectioned view for this utility model;

Accompanying drawing 2 is accompanying drawing 1 an arc-shaped spring piece front view;

Accompanying drawing 3 is that the A of accompanying drawing 2 is to view;

Below with reference to the accompanying drawings this utility model is described in detail:

Show that as accompanying drawing 1,2,3 this utility model is made of two ear clip listening tubes (1) (2), threeway sebific duct (7), auscultation head (9), arc-shaped spring piece (6).In threeway sebific duct (7), insert arc-shaped spring piece (6), spring leaf two ends (3) (5) is the opening ring-type, two ear clips listen pipe end (4) (8) to be screw-like, and insert in the split ring (3) (5) of spring leaf two ends screw-like termination (4) (8).

This utility model is owing to insert sebific duct with arc-shaped spring piece, make the stethoscope outward appearance succinct, because spring leaf makes chucking power soft with the end connection (referring to compare with old-fashioned identical elastic spring leaf) of ear clip listening tube, obviously be better than old-fashioned stethoscope again through inventor's trial effect in one period.Manufacturing process is also very simple.
