[0031] The human nervous system is complex, so diagnosis and treatment are also very difficult. The more common tools for diagnosis are percussion hammers; the percussion hammer is used to judge the patient's reaction after tapping the relevant parts of the body, and the severity of the condition is reflected by the strength of the tapping.

[0032] The existing percussion hammer usually consists of a handle and a hammer head, and its structure is relatively fixed. For doctors who are away from home, conventional percussion hammers will take up a large space in the medicine box. Moreover, during use, neurologists need to put the percussion hammer in their pockets. However, the existing percussion hammers are large and often take up a large space when put in pockets, making them inconvenient to carry.

[0033] See also Figures 1 to 9 The present application provides a nerve percussion hammer, including a telescopic handle 100 and a hammer body 200, wherein the hammer body 200 includes a sleeve 210, a hammer head 220, an end plate 230 and a press-type elastic self-locking mechanism.

[0034] Specifically, the sleeve 210 is fixedly connected to the telescopic handle 100, and first slide grooves 211 are provided on both sides of the inner wall of the sleeve 210, and the first slide grooves 211 extend along the length direction of the sleeve 210, and the end plate 230 is fixed to one end of the sleeve 210. The hammer head 220 is slidably assembled in the sleeve 210 and extends from the other end of the sleeve 210, and slide rails 221 are respectively provided on both sides of the hammer head 220, and the slide rails 221 are assembled in the first slide grooves 211 to realize the sliding assembly of the hammer head 220 and the sleeve 210.

[0035] The push-type elastic self-locking mechanism is arranged in the sleeve 210, and the hammer head 220 is connected to the push-type elastic self-locking mechanism so that the hammer head 220 has a released state extending out of the sleeve 210 and a hidden state hidden in the sleeve 210. The push-type elastic self-locking mechanism includes an elastic component 310, a slot structure 320 and a hook 330. The elastic component 310 is arranged in the sleeve 210 and connects the hammer head 220 and the end plate 230. The slot structure 320 is arranged on the slide rail. The slot structure 320 has a limiting slot. The hook 330 is arranged in the first slide slot 211. The hook 330 is inserted into the limiting slot in the hidden state, and the hook 330 is disengaged from the limiting slot in the released state.

[0036] It is understandable that, in the above technical solution, by improving the hammer body 200, the hammer head 220 is designed to be slidably connected with the sleeve, and has a release state extending out of the sleeve and a hidden state hidden in the sleeve through a push-type elastic self-locking mechanism. During use, the push-type elastic self-locking mechanism can lock the hammer head 220 pressed into the sleeve 210, and when the hammer head 220 hidden in the sleeve 210 is pressed, the push-type elastic self-locking mechanism can release the hammer head 220 and make the hammer head 220 extend out of the sleeve 210.

[0037] When the nerve percussion hammer is not in use, the telescopic handle 100 is retracted and the hammer head 220 is pressed. The hammer head 220 overcomes the elastic force of the elastic component 310 and extends into the sleeve 210. The hook 330 is engaged in the limiting groove, thereby locking the hammer head 220 in a hidden state. In this way, the overall volume of the entire percussion hammer becomes smaller, the occupied space is smaller, and it is very convenient to carry. When in use, the telescopic handle 100 is directly extended, and then the hammer head 220 hidden in the sleeve 210 is pressed. The hook 330 is disengaged from the limiting groove, thereby switching the hammer head 220 to a released state, and the elastic component 310 pops the hammer head 220 out of the sleeve 210.

[0038] The nerve percussion hammer of this embodiment has an adjustable overall structure, and the hammer head can be hidden in the sleeve and locked by a push-type elastic self-locking mechanism. The overall space occupied is small and convenient to carry. When in use, the hammer head can be released and extended from the sleeve by the push-type elastic self-locking mechanism.

[0039] The slide rails 221 disposed on both sides of the hammer head 220 extend along the length direction of the hammer head 220 . When the hammer head 220 slides in the sleeve 210 , it can only slide stably along the first slide groove 211 .

[0040] Furthermore, both ends of the first slide groove 211 are closed. In this way, after the slide rails 221 on both sides of the hammer head 220 are assembled into the two first slide grooves 211, the slide rails 221 can only slide within the travel range of the first slide groove 211 and will not be separated from the first slide groove 211.

[0041] Specifically, refer to Figure 7 One end of the first slide groove 211 extends to the middle of the sleeve 210, and the other end extends to the rear end edge of the sleeve 210 to form a rectangular opening, and a first limit block 2110 is installed at the rectangular opening. During the assembly of the percussion hammer, after the slide rails 221 on both sides of the hammer head 220 are assembled into the first slide groove 211, the first limit block 2110 is installed at the rectangular opening to close the end of the first slide groove 211.

[0042] In some embodiments, reference Figures 3 to 6 The slot structure 320 further includes a first guide slot 3200 and a second guide slot 3201. The first guide slot 3200 and the second guide slot 3201 are both provided on the slide rail 221. The first guide slot 3200 forms a first opening 3202 at one end of the slide rail 221 facing the elastic component 310. The second guide slot 3201 forms a second opening 3203 at one end of the slide rail 221 facing the elastic component 310. The limiting slot is provided on the slide rail 221. The limiting slot and the end of the first guide slot 3200 away from the first opening 3202 are connected by a first arc guide. The groove 3204 is connected, and the limiting groove is connected to the end of the second guide groove 3201 away from the second opening 3203 through the second arc-shaped guide groove 3205. The groove wall on one side of the limiting groove is provided with a first guiding slope 3206 and a second guiding slope 3207, and the groove wall on the other side of the limiting groove is provided with a groove 3208. The first guiding slope 3206 and the second guiding slope 3207 are connected at an angle to each other and are spaced from the groove 3208. The connection between the first guiding slope 3206 and the second guiding slope 3207 is inclined toward the first guide groove 3200.

[0043] In some other embodiments, the hook 330 is installed in the first sliding groove 211 via a torsion spring so that the hook 330 is aligned with the first opening 3202 .

[0044] Specifically, refer to Figure 7 , Figure 8 The first slide groove 211 extends to one end of the middle part of the sleeve 210 to form an avoidance groove 2110, one end of the hook 330 extends into the avoidance groove 2110 and is rotatably connected to the inner wall of the avoidance groove 2110 through a rotating shaft, the torsion spring is sleeved on the rotating shaft, the leg at one end of the torsion spring is stuck on the rotating shaft, and the leg at the other end of the torsion spring is stuck on the groove wall of the avoidance groove 2110. The hook 330 is always kept in a position aligned with the first opening 3202 under the action of the torsion spring. In this way, when the hammer head 220 is locked, the hook 330 can accurately enter the first opening 3202 to avoid the hook 330 being misplaced and unable to enter from the first opening 3202.

[0045] Among them, the first guide groove 3200 and the second guide groove 3201 are both horizontally opened on the slide rail 221, and the first guide groove 3200 and the second guide groove 3201 are parallel to each other. Under normal conditions, the hammer head 220 extends out of the sleeve 210 under the elastic force of the elastic component 310. At this time, the slot structure 320 and the hook 330 are far apart. When the hammer head 220 needs to be hidden inside the sleeve 210, since the hook 330 is aligned with the position of the first opening 3202 under the force of the torsion spring, when the hammer head 220 is pressed hard, the hook 330 will enter the first guide groove 3200 from the first opening 3202, and then follow the first guide groove 3200 through the first arc-shaped guide groove 3204 and the first guide slope 3206 and hook into the groove 3208. At this time, the force applied is released. Under the force on the hammer head 220, the hook 330 will hook on the groove 3208 of the limiting groove, so that the hammer head 220 is locked. When the hammer head 220 needs to be extended from the sleeve 210, the hammer head 220 hidden in the sleeve 210 is pressed. Since the connection between the first guide slope 3206 and the second guide slope 3207 is inclined toward the first guide groove 3200, the hook 330 will enter the second guide groove 3201 along the second guide slope 3207 through the second arc guide groove 3205. At this time, the force applied to the hammer head 220 is released. Under the action of the rebound force of the elastic component 310, the elastic component 310 will push the hammer head 220 to extend from the sleeve 210, and the hook 330 will slide out of the second opening 3203 along the second guide groove 3201.

[0046] In order to facilitate the hook 330 to enter the first guide groove 3200 , in some embodiments, chamfers are provided on both sides of the first opening 3202 , which is equivalent to expanding the first opening 3202 .

[0047] The sleeve 210 is a cylindrical tube structure, the end plate 230 is a circular plate, the end plate 230 is fixed at one end of the sleeve 210, the hammer head 220 is a cylindrical structure, the hammer head 220 is assembled inside the sleeve 210, the elastic component 310 is a columnar spring, one end of the elastic component 310 is fixed on the hammer head 220, and the other end is connected to the end plate 230. The elastic component 310 is in a compressed state in the sleeve 210, so in the process of using the percussion hammer, the elastic component 310 also plays a buffering role.

[0048] In some embodiments, a rubber ball head 222 is disposed at one end of the hammer head 220 extending out of the sleeve 210. The rubber ball head 222 is in direct contact with the patient during the percussion process.

[0049] In some embodiments, the nerve percussion hammer also includes an adjustment mechanism, which includes an adjustment bolt 410 and an adjustment slide 420. The adjustment slide 420 is slidably assembled in the sleeve 210. One end of the elastic component 310 is connected to the hammer head 220, and the other end is connected to the adjustment slide 420. The adjustment bolt 410 is threadedly connected to the end plate 230. One end of the adjustment bolt 410 is located on the outside of the end plate 230, and the other end is pressed against the adjustment slide 420.

[0050] Specifically, a threaded hole is provided in the middle of the end plate 230, and the adjusting bolt 410 is connected to the threaded hole in the middle of the end plate 230. One end of the adjusting bolt 410 extends into the sleeve 210 and is tightly pressed against the adjusting slide plate 420, and the other end is located on the outside of the end plate 230. When the elasticity of the elastic component 310 needs to be adjusted, the adjusting bolt 410 is rotated, and the adjusting bolt 410 will push the adjusting slide plate 420 to slide in the sleeve 210, thereby making the distance between the adjusting slide plate 420 and the hammer head 220 closer, so that the elastic force applied by the elastic component 310 to the hammer head 220 is greater, and the hammer head 220 is more powerful during the knocking process. When the adjusting bolt 410 is rotated in the opposite direction, the elastic component 310 will push the adjusting slide plate 420 away from the hammer head 220. At this time, the force applied by the elastic component 310 on the hammer head 220 becomes smaller, and the force of the hammer head 220 is more moderate during the knocking process.

[0051] In order to ensure that the adjusting slide 420 slides stably in the sleeve 210, in some embodiments, sliders 421 are provided on both sides of the adjusting slide 420, and second slide grooves 212 are provided on both sides of the inner wall of the sleeve 210. The second slide grooves 212 extend along the length direction of the sleeve 210, and the sliders 421 are assembled in the second slide grooves 212.

[0052] Furthermore, both ends of the second slide groove 212 are closed so that the adjusting slide plate 420 can only slide within the travel range of the second slide groove 212 and will not be separated from the second slide groove 212.

[0053] Specifically, one end of the second slide groove 212 extends to the middle of the sleeve 210, and the other end extends to the front edge of the sleeve 210 to form a rectangular opening, and a second limit block 2120 is installed at the rectangular opening. During the assembly of the percussion hammer, the sliders 421 on both sides of the adjustment slide 420 are assembled into the second slide groove 212, and then the second limit block 2120 is installed at the rectangular opening to close the end of the second slide groove 212.

[0054] In some embodiments, the first slide groove 211 and the second slide groove 212 are staggered inside the sleeve 210. This can avoid interference between the sliding of the hammer head 220 and the adjusting slide plate 420.

[0055] Reference Figure 7 , Fig. 9In the present application, the two first slide grooves 211 are distributed in the left-right direction inside the sleeve 210, and the two second slide grooves 212 are distributed in the up-down direction inside the sleeve 210. Avoid the first slide groove 211 and the second slide groove 212 from conflicting.

[0056] In some embodiments, the telescopic handle 100 includes a fixed rod 101 and a sliding cylinder 102 , one end of the fixed rod 101 is fixedly connected to the sleeve 210 , and the other end of the fixed rod 101 is slidably assembled in the sliding cylinder 102 .

[0057] In some embodiments, a limiting spring piece 1010 is provided on the fixed rod 101, and a limiting hole for cooperating with the limiting spring piece 1010 is provided on the sliding cylinder 102. When the telescopic handle 100 needs to be extended, the sliding cylinder 102 is pulled until the limiting spring piece 1010 on the fixed rod 101 enters the limiting hole on the sliding cylinder 102, indicating that the sliding cylinder 102 is stretched to the right position, and the limiting spring piece 1010 can play a limiting role to prevent the sliding cylinder 102 from sliding relative to the fixed rod 101. When the telescopic handle 100 needs to be retracted, the limiting spring piece 1010 is pressed so that the limiting spring piece 1010 sinks into the limiting hole, and then the sliding cylinder 102 is pushed so that the sliding cylinder 102 overlaps with the fixed rod 101.
