[0030] In order to better understand the purpose, structure and function of the utility model, the utility model is further described in detail below with reference to the accompanying drawings.

[0031] like Figure 1-7As shown, a percussion hammer for neurological examination of the utility model comprises a hammer head 1, and external threads are provided on the surfaces of both ends of the hammer head 1, a first rubber 3 is installed at one end of the hammer head 1, a first internal thread ring 5 is bonded to the surface of the first rubber 3, and a first latch 6 is fixedly connected to the surface of the first internal thread ring 5. By installing the first latch 6, when it is necessary to rotate the first internal thread ring 5, the position with the first latch 6 can be held by hand, and the first latch 6 provides a strong friction force, which is more stable during rotation. A second rubber 4 is installed at the other end of the hammer head 1, a second internal thread ring 7 is bonded to the surface of the second rubber 4, and a second latch 8 is fixedly connected to the surface of the second internal thread ring 7. By installing the first internal thread ring 5 and the second internal thread ring 7, the external threads, the first internal thread ring 5 and the second internal thread ring 7 are used to provide the first rubber 3 and the second rubber 4 with an installable and disassembleable effect. When the percussion hammer is oxidized and hardened after long-term use, the first rubber 3 or the second rubber 4 can be replaced by the first internal thread ring 5 or the second internal thread ring 7, which is very convenient to use.

[0032] A first telescopic rod 2 is installed on the surface of the hammer head 1, and an external thread is provided on the surface of the first telescopic rod 2. A second telescopic rod 24 is installed on the surface of the first telescopic rod 2. One end of the first telescopic rod 2 is fixedly connected to the first limiting ring 16, and one end of the second telescopic rod 24 is welded with a third internal thread ring 14. The other end of the second telescopic rod 24 is fixedly connected to the second limiting ring 17. An external thread is provided on the surface of the second telescopic rod 24. A third telescopic rod 13 is installed on the surface of the second telescopic rod 24, and a fourth internal thread ring 15 is welded at one end of the third telescopic rod 13. By installing the first telescopic rod 2, the second telescopic rod 24 and the third telescopic rod 13, when the percussion hammer needs to be stored, the second telescopic rod 24 and the third telescopic rod 13 can be rotated, and then the first telescopic rod 2 is put into the second telescopic rod 24, and the second telescopic rod 24 is put into the third telescopic rod 13. At this time, the length of the hammer handle is shortened, and the space occupied by the percussion hammer is reduced, making it more convenient to store.

[0033] An internal threaded hole 20 is provided at the other end of the first telescopic rod 2, and a hole 22 is provided on the surface of the hammer head 1. The other end of the first telescopic rod 2 is embedded in the hole 22. A limiting groove 23 is provided on the surface of the hammer head 1. A screw 21 is installed in the limiting groove 23. One end of the screw 21 is installed in the internal threaded hole 20. By providing the limiting groove 23, the body of the screw 21 can be completely embedded in the hammer head 1, so that the screw 21 will not touch external objects, thereby improving the protection during use.

[0034] The bottom of the first rubber 3 is fixedly connected to the first positioning rod 9, a first positioning hole 11 is provided at one end of the hammer head 1, and the first positioning rod 9 is embedded in the first positioning hole 11; the bottom of the second rubber 4 is fixedly connected to the second positioning rod 10, a second positioning hole 12 is provided at the other end of the hammer head 1, and the second positioning rod 10 is embedded in the second positioning hole 12. By installing the first positioning rod 9 and providing the first positioning hole 11, when the first rubber 3 needs to be installed, the first positioning rod 9 can be embedded in the first positioning hole 11 first, which provides a positioning effect for the first rubber 3 during installation, making the installation more convenient.

[0035] An anti-slip sleeve 18 is welded on the surface of the third telescopic rod 13, and soft spheres 19 are bonded to the surface of the anti-slip sleeve 18. The soft spheres 19 are distributed in an equidistant manner. By installing the anti-slip sleeve 18, when using the percussion hammer, the anti-slip sleeve 18 can be used to increase the friction between the palm and the third telescopic rod 13, making the grip of the percussion hammer more stable.

[0036] The first latch teeth 6 are distributed in an annular form, and the second latch teeth 8 are distributed in an annular form. Through the distribution of the first latch teeth 6, when the first rubber 3 is rotated, the first latch teeth 6 can be used to evenly distribute the rotation force, which is more labor-saving when used.

[0037] The working principle of the percussion hammer for neurological examination is as follows: when using the percussion hammer for neurological examination, the first internally threaded ring 5 should be rotated first and installed at one end of the hammer head 1, and the first positioning rod 9 should be inserted into the first positioning hole 11, and the first latch 6 should be used to provide a strong friction force to install the first internally threaded ring 5 at one end of the hammer head 1. At this time, the first rubber 3 is also installed at one end of the hammer head 1, and then the second positioning rod 10 is embedded in the second positioning hole 12, and the second internally threaded ring 7 is rotated and installed at the other end of the hammer head 1. At this time, the second rubber 4 is installed at the other end of the hammer head 1. When the percussion hammer is oxidized and hardened after long-term use, the first rubber 3 or the second rubber 4 can be replaced by the first internally threaded ring 5 or the second internally threaded ring 7. It is very convenient to use, and there is no need to directly replace the entire percussion hammer, which reduces the maintenance cost. The third telescopic rod 13 is then rotated, and the fourth internally threaded ring 15 will move on the external thread on the surface of the second telescopic rod 24. When the side surface of the fourth internally threaded ring 15 is in contact with the side surface of the second limiting ring 17, the third telescopic rod 13 will be fixed. The second telescopic rod 24 is then rotated, and the third internally threaded ring 14 will move on the external thread on the surface of the second telescopic rod 24. When the side surface of the third internally threaded ring is in contact with the side surface of the first limiting ring 16, the second telescopic rod 24 will be fixed. At this time, the percussion hammer for neurological examination can be used normally. When the percussion hammer needs to be stored after use, the second telescopic rod 24 and the third telescopic rod 13 can be rotated, and then the first telescopic rod 2 can be put into the second telescopic rod 24, and the second telescopic rod 24 can be put into the third telescopic rod 13. At this time, the length of the hammer handle is shortened, and the space occupied by the percussion hammer is reduced, making it more convenient to store.
