[0036] The following further details the embodiments of the present invention with reference to the drawings:

[0037] See Figures 1 to 8 , a tympanic membrane fixing bracket provided by the present invention includes a U-shaped sliding plate 1, a support rod 2, a sliding seat 3, a large drum top seat 4, and a memory ring 5.

[0038] As Figures 1 to 3 shown, the U-shaped sliding plate 1 includes a bottom plate 11 and two side plates 12 integrally formed. The two side plates 12 are symmetrically connected to both sides of the upper end of the bottom plate 11. In order to strengthen the structural strength of the entire U-shaped sliding plate 1, a connecting rod 13 is also connected between the two side plates 12; the middle part of the lower end of the bottom plate 11 is fixedly connected to the upper end of the support rod 2, and the two are fixedly connected by welding. The U-shaped sliding plate 1 is inclined forward at a certain angle with respect to the support rod 2. Preferably, the included angle between the U-shaped sliding plate 1 and the support rod 2 is 150°.

[0039] As Figure 1 and Figure 4 shown, the sliding seat 3 is made of aluminum profile. The sliding seat 3 includes an arc-shaped plate 31 and two groove plates 32 integrally formed. The inner wall of the arc-shaped plate 31 is fitted to the outer wall of the drum cavity of the tympanic membrane 100 and the arc-shaped plate 31 is locked to the tympanic membrane 100 by bolts. The two groove plates 32 are symmetrically fixed to the outer wall of the arc-shaped plate 31, and a chute 33 is formed between the two groove plates 32. There are two sliding seats 3 in total, and the two sliding seats 3 are respectively assembled on the two side plates 12 through their respective chutes 33 and limited by the bottom plate 11. That is, the two tympanic membranes 100 can be symmetrically installed on both sides of the U-shaped sliding plate 1 through the two sliding seats 3. Moreover, since the U-shaped sliding plate 1 and the support rod 2 are arranged at a certain angle, the two tympanic membranes 100 can also be inclined to facilitate percussion.

[0040] As Figures 1 to 3 shown, the support rod 2 is a solid rod or a tubular structure. Its lower part is inserted into the large drum top seat 4 and its height is adjustable. After insertion, the support rod 2 is locked by the butterfly wrench 42 on the large drum top seat 4.

[0041] As shown Figure 1 , Figures 5 to 7 in the figure, the top seat 4 of the big drum is installed upward on the outer wall of the drum cavity of the big drum 200. The top seat 4 of the big drum includes a seat body 41, a butterfly wrench 42 and a setscrew piece 43. The bottom surface of the seat body 41 is attached to the outer wall of the drum cavity of the big drum 200, and the seat body 41 is fixed on the outer wall of the drum cavity of the big drum 200 by bolts. A mounting hole 44 is formed through the middle of the seat body 41. The diameter of the mounting hole 44 matches the outer diameter of the support rod 2 and can be inserted by the support rod 2. The butterfly wrench 42 is threadedly connected to one side of the seat body 41. The setscrew piece 43 is an elastic bending piece. A long circular hole 431 is formed at one end of the setscrew piece 43, and this end is also sleeved on the butterfly wrench 42 by using the long circular hole 431. The setscrew piece 43 is connected to the butterfly wrench 42 together, which can solve the problem that the setscrew piece 43 is easily lost. The other end of the setscrew piece 43 is placed in the mounting hole 44 and contacts the front end of the butterfly wrench 42. After the support rod 2 is inserted into the mounting hole 44, the setscrew piece 43 can be pressed against the support rod 2 by rotating the butterfly wrench 42 to realize the locking between the support rod 2 and the seat body 41. Among them, the surface of the setscrew piece 43 in contact with the support rod 2 is an arc surface 432, and the arc surface 432 can be fitted with the outer wall of the support rod 2. The pressing force applied by the butterfly wrench 42 is transmitted to the arc surface 432, and the arc surface 432 then distributes the pressing force on the support rod 2, which can improve the stability of the support rod 2 after being pressed.

[0042] As shown Figure 1 and Figure 8 in the figure, a memory ring 5 is also sleeved on the support rod 2. The memory ring 5 includes an opening ring 51 and a locking bolt 52. The opening ring 51 is slidably sleeved on the support rod 2. Two wing plates 53 are symmetrically formed on both sides of the opening of the opening ring 51. The locking bolt 52 passes through and is threadedly connected to the two wing plates 53 to lock the opening ring 51 on the support rod 2. A positioning block 54 is integrally formed on the lower end surface of the opening ring 51. Correspondingly, a positioning groove 45 is also formed on the seat body 41 of the top seat 4 of the big drum. When the support rod 2 is inserted into the mounting hole 44, the positioning block 54 can be inserted into the positioning groove 45 in a matching manner. By using the memory ring 5, the support rod 2 can be quickly adjusted to the position at the previous use, which greatly improves the assembly efficiency.

[0043] In summary, the content of the present invention is not limited to the above embodiments. Those skilled in the art can propose other embodiments within the guiding ideology of the present invention, but these embodiments are all included within the scope of the present invention.
