[0029] Reference Figure 3-Figure 5 The inner wall of the hammer handle 2 is slidably connected with the inner shell 6, and the left and right sides of the outside of the bottom block 5 are slidably connected to the inner walls on both sides of the bottom end of the inner shell 6 respectively. The hammer handle 2 here plays a supporting and protective role for the inner shell 6, and the outside of the limit column 3 is slidably connected to the inner wall of the inner shell 6. The bottom end of the inner wall of the inner shell 6 is fixedly connected to two top blocks 7, and the outside of the bottom block 5 is slidably connected to the adjacent side of the two top blocks 7. Here, the bottom block 5 will gradually clamp with the two top blocks 7 when rising, thereby fixing the inner shell 6 inside the hammer handle 2.

[0030] Reference Figure 3-Figure 5 The top of the inner shell 6 is fixedly connected to a support block 8, the top of the threaded rod 4 is rotatably connected to the bottom of the support block 8, the top of the support block 8 is detachably connected to a knocking assembly, and the knocking assembly here is the main part for percussing the patient, and the knocking assembly includes a hammer body 9, the inner wall of the support block 8 is in contact with the outside of the hammer body 9, and the bottom end of the hammer body 9 is detachably connected to the top of the support block 8, and the support block 8 here provides a stable support for the hammer body 9, and the right side of the hammer body 9 is fixedly connected to a rubber body 10.

[0031] Reference Figure 3 , Figure 6 and Figure 7The rubber body 10 here can ensure that the doctor's knocking force and frequency will not cause harm to the patient's knocked part. The inner wall of the rear end of the support block 8 is slidably connected with a buckle assembly, and the buckle assembly includes a column 11. The outside of the column 11 is slidably connected to the inner wall of the hammer body 9. The buckle assembly here is used to facilitate the disassembly of the hammer body 9 for cleaning or repair and replacement. The outside of the column 11 is slidably connected to the inner wall of the rear end of the support block 8, and an empty groove 12 is opened inside the column 11.

[0032] Reference Figure 7 A spring 13 is arranged inside the empty slot 12. The spring 13 here mainly plays a resetting role. The two ends of the spring 13 are respectively fixedly connected to the front and rear ends of the inner wall of the empty slot 12. A slider 14 is fixedly connected to the middle of the spring 13. The outer part of the slider 14 is slidably connected to the inner wall of the empty slot 12. The empty slot 12 here provides a stable sliding space for the slider 14. A button 15 is fixedly connected to the middle of the slider 14. Balls 16 are slidably connected to both sides of the inner wall of the front end of the column 11 here.

[0033] Reference Figure 1 and Figure 7 The outsides of the two balls 16 are respectively slidably connected to the left and right sides of the inner wall of the hammer body 9, and the adjacent sides of the two balls 16 are fixedly connected to the limit blocks 17. The outside of the limit blocks 17 are slidably connected to the inner wall of the empty groove 12. The front ends of the pull button 15 are provided with card slots 18. When the pull button 15 is pulled here, the two card slots 18 at the front end will engage with the balls 16, so that the column 11 can be smoothly pulled out from the inside of the hammer body 9, thereby achieving the purpose of quickly disassembling the hammer body 9.

[0034] Working principle: When the doctor needs to adjust the length of the percussion hammer for neurology, he can pull the hammer body 9, and the hammer body 9 will drive the inner shell 6 below to move upward, and at the same time drive the top block 7 inside to move upward. When it moves to a suitable distance, the knob 1 can be turned. At this time, the knob 1 will drive the threaded rod 4 to rotate, and the threaded rod 4 will drive the bottom block 5 thereon to rotate. When the bottom block 5 rotates, it is limited by the hammer handle 2, so it makes a translational movement upward until it moves back to the inside of the inner shell 6.

[0035] At this time, continue to turn the knob 1 to allow the bottom block 5 to slowly pass through the top blocks 7. At the same time, because the spacing between the top ends of the top blocks 7 becomes smaller and smaller, the inner shell 6 will be stuck inside the hammer handle 2 after it moves to the maximum distance. At this time, the length adjustment of the percussion hammer for neurology is completed. At this time, the doctor can hold the hammer handle 2 and use the rubber body 10 on the right side of the hammer body 9 to percuss the patient. At this time, the percussion hammer with a good length adjustment can control the movement of the hammer more accurately to ensure accurate feedback information during the examination.

[0036] After long-term use, the rubber body 10 needs to be replaced. At this time, the pull button 15 can be pulled. When the pull button 15 is pulled, the slot 18 at the bottom thereof will engage with the ball 16. The limit block 17 here ensures that the ball 16 will only make left and right translational motions and will not deviate. After the engagement, the column 11 is pulled out together with it. At this time, the rubber body 10 can be disassembled for cleaning or maintenance.

[0037] After cleaning or maintenance is completed, the rubber body 10 is placed back on the top of the support block 8. At this time, the operation can be reversed to re-fix the rubber body 10 on the top of the support block 8. The spring 13 inside the empty groove 12 here is used for resetting, and the slider 14 in the middle plays a balancing role, so that the column 11 will not separate from the support block 8 and the inside of the hammer body 9 under normal conditions.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
