[0035] Please refer to Figure 2, the hammer handle 3 comprises a first rod segment 31, a second rod segment 32 and a third rod segment 33 which are all round rods and are sequentially sleeved. Specifically, one end of the first rod segment 31 is hingedly connected with the connecting rod 41, the other end extends into the second rod segment 32 and is slidably connected with the second rod segment 32, one end of the second rod segment 32 away from the first rod segment 31 is slidably connected with the third rod segment 33, a first locking piece 5 is arranged between the first rod segment 31 and the second rod segment 32, and a second locking piece 6 is arranged between the second rod segment 32 and the third rod segment 33. In the embodiment, in order to make the length of the extended hammer handle 3 meet the use requirement and ensure that the hammer handle 3 can be completely accommodated in the accommodating groove 11 of the hammer body 1 after being retracted, the hammer handle 3 is provided in three segments. Alternatively, the hammer handle 3 can be provided in two segments or four segments according to the actual use requirement.

[0036] When the hammer handle 3 is adjusted to the use state, the hammer handle 3 is rotated to be perpendicular to the hammer body 1, the first rod segment 31 of the hammer handle 3 is locked by the locking device 4, the second rod segment 32 is slid to the end of the first rod segment 31 and is locked by the first locking piece 5, the third rod segment 33 is slid to the end of the second rod segment 32 and is locked by the second locking piece 6, and the hammer handle 3 is locked in the use state, thereby facilitating the use of the user.

[0037] Please refer to Figure 3 In order to prevent the first rod segment 31, the second rod segment 32 and the third rod segment 33 from being separated from each other, they need to be limited. Specifically, a first limiting block 34 is coaxially welded to one end of the first rod segment 31 close to the second rod segment 32, a second limiting block 35 is coaxially welded to one end of the second rod segment 32 close to the third rod segment 33, the first limiting block 34 and the second limiting block 35 are both cylindrical, the diameter of the first limiting block 34 is greater than the diameter of the first rod segment 31, the diameter of the second limiting block 35 is greater than the diameter of the second rod segment 32, the inner diameter of the second rod segment 32 close to the first rod segment 31 is the same as the diameter of the first rod segment 31, the inner diameter of the third rod segment 33 close to the second rod segment 32 is the same as the diameter of the second rod segment 32, the first limiting block 34 slides in the inside of the second rod segment 32, and the second limiting block 35 slides in the inside of the third rod segment 33. The first rod segment 31, the second rod segment 32 and the third rod segment 33 are arranged in a stepped manner, so that the first rod segment 31, the second rod segment 32 and the third rod segment 33 are limited to each other, effectively solving the problem that the first rod segment 31, the second rod segment 32 and the third rod segment 33 are separated from each other and are inconvenient to use, and further improving the convenience of the percussion hammer in use and accommodation.

[0038] Because the percussion hammer exerts a small force when in use, locking the first rod segment 31, the second rod segment 32 and the third rod segment 33 by friction can meet the use requirements of the percussion hammer. In the embodiment, the first locking member 5 and the second locking member 6 are both butterfly bolts, the first locking member 5 is threadedly connected with the first rod segment 31 and can abut against the second rod segment 32, and the second locking member 6 is threadedly connected with the second rod segment 32 and can abut against the second rod segment 32. The butterfly bolt is convenient for the user to twist, thereby facilitating the user to operate the extension and retraction of the hammer handle 3.

[0039] Please refer to Figure 2 The third rod segment 33 is provided with an anti-skid layer made of rubber or silicone, the anti-skid layer is provided with anti-skid lines to improve the comfort and stability of the user's holding, and the diameter of the anti-skid layer is slightly larger than the width of the accommodating groove 11, so that when the hammer handle 3 is accommodated into the accommodating groove 11, the anti-skid layer is compressed to a certain extent, the anti-skid layer abuts against the side wall of the accommodating groove 11, so that the hammer handle 3 can be stably clamped in the accommodating groove 11, thereby improving the stability of the accommodating groove 11.

[0040] Because the elastic hammer head 2 is more likely to be worn out with the increase of the use time, the elastic hammer head 2 is detachably connected with the hammer body 1, in the embodiment, the elastic hammer head 2 is threadedly connected with the hammer body 1, that is, a threaded cylinder is fixedly attached to the end of the elastic hammer head 2 close to the hammer body 1, a threaded column is fixedly welded to the end of the hammer body 1 close to the elastic hammer head 2, and the threaded cylinder and the threaded column are threadedly connected, thereby realizing the assembly of the elastic hammer head 2 and the hammer body 1.

[0041] Please refer to Figure 4 Because the percussion hammer is usually matched with the touch needle 7 to monitor the patient, and the touch needle 7 usually needs to be separately accommodated, the touch needle 7 is thin and sharp, is very easy to be lost, and has a certain danger, therefore, the percussion hammer can realize the use and accommodation of the touch needle 7 by movably arranging the touch needle 7 in the hammer body 1 and arranging the driving assembly 8 on the hammer body 1 to drive the touch needle 7 to be retracted into or protrude out of the hammer body 1.

[0042] Specifically, the hammer body 1 is internally provided with a sliding groove 12, the sliding groove 12 is open towards the end of the hammer body 1 away from the elastic hammer head 2, the driving gear 81 is rotationally connected with the hammer body 1 and at least partially protrudes from the top surface of the hammer body 1, so as to facilitate the user to rotate the driving gear 81 from the outside, the width of the driving rack 82 is the same as the width of the sliding groove 12, and the driving rack 82 is slidingly connected with the hammer body 1 along the sliding groove 12, the tail end of the tactile needle 7 is welded and fixed with the driving rack 82, and the needle head is arranged towards the opening of the sliding groove 12. When the tactile needle 7 is needed, the driving gear 81 is rotated, the driving gear 81 drives the driving rack 82 to slide towards the opening of the sliding groove 12, so that the tactile needle 7 protrudes from the sliding groove 12, and when the tactile test is performed, the user holds the driving gear 81, so as to ensure that the tactile needle 7 can effectively puncture.

[0043] In order to protect the tactile needle 7 and reduce the possibility of damage to the tactile needle 7, the hammer body 1 is adhesively fixed with a sealing layer 13 at the opening of the sliding groove 12, the sealing layer 13 is made of rubber or silicone, the sealing layer 13 fills and seals the opening of the sliding groove 12, and the sealing layer 13 is provided with an avoiding hole through which the tactile needle 7 is arranged to be accommodated in the sliding groove 12, so that the sealing layer 13 isolates the tactile needle 7 from the outside when the tactile needle 7 is accommodated in the sliding groove 12, thereby effectively protecting the tactile needle 7.

[0044] Please refer to Figure 5 When the hammer handle 3 is completely accommodated in the accommodating groove 11 on the hammer body 1, the driving gear 81 is rotated, so that the tactile needle 7 protrudes from the hammer body 1, the user holds the hammer body 1 and presses the driving gear 81, so as to perform tactile detection, after the detection is completed, the driving gear 81 is reversely rotated, so as to accommodate the tactile needle 7 in the hammer body 1, and the sealing layer 13 can hinder the tactile needle 7 from sliding out of the hammer body 1 to a certain extent.

[0045] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
