[0029] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0030] See also Figures 1 to 4 The embodiment of the utility model provides a stethoscope hammer with a convenient replacement of the hammer head, the stethoscope hammer with a convenient replacement of the hammer head comprises a handle 1, and also comprises:

[0031] The positioning frame 2 is U-shaped and fixed to the end of the handle 1. A rubber hammer head 3 is fixed to one side of the positioning frame 2;

[0032] The mounting seat 5 is cylindrical and rotates on the positioning frame 2. One end of the mounting seat 5 is provided with a plurality of cylindrical cavities 6 distributed in an annular shape. Different types of auxiliary hammer pieces 8 are installed inside any cavity 6. A plurality of hanging plates 11 distributed in an annular shape are welded to the outside of the mounting seat 5.

[0033] The fixing member 10 slides outside the mounting seat 5 along the axial direction, and is also fixed to the auxiliary hammer member 8 and can be buckled on the hanging plate 11. In the buckled state, the auxiliary hammer member 8 extends to the outside of the cavity 6.

[0034] It should be noted that: in this type of auscultation hammer, a colloid hammer head 3 is arranged on one side of the positioning frame 2, and a plurality of different types of auxiliary hammer head pieces 8 are arranged inside the mounting seat 5. The positions of the auxiliary hammer head pieces 8 can be changed by rotating the mounting seat 5, so that the type to be used can be changed, which is more convenient to adjust and more practical.
