[0046] Embodiment 1

[0047] It should be noted that after the clamping adjustment mechanism 100 clamps the toothbrush, the first adjustment rod 33 is rotated in the second direction, the first adjustment rod 33 drives the adapter 32 to rotate, and the movable member 31 restricts the rotation of the adapter 32, so that the adapter 32 has a moving path that slides on the first adjustment rod 33; there is an active gap between the adapter 32 and the movable member 31, and the movable member 31 can move in the radial direction of the adapter 32. When the adapter 32 moves along a straight line, it drives the movable member 31 to translate upward to the highest point, or translate downward to the lowest point. The movable member 31 has an arc-shaped moving path, so that the movable member 31 drives the first clamping member 21 to rotate and adjust, so as to adjust the inclination angle of the toothbrush. In other embodiments, the first adjustment rod 33 and the adapter 32 are used to drive the movable member 31 to move. As long as there is an active gap between the first adjustment rod 33 and the movable member 31 and the rotation point of the movable member 31, the angle adjustment of the clamping assembly 2 can be achieved, and no special restrictions are made here.

[0048] The utility model proposes a clamping adjustment mechanism 100, such as Figures 1 to 3 As shown, it includes: a supporting component 1, a clamping component 2, and an adjusting component 3. The clamping component 2 includes a first clamping member 21 and a second clamping member 25. In a first direction, the first end of the first clamping member 21 is movably arranged on the supporting component 1; the second clamping member 25 is movably installed on the first clamping member 21, and a clamping position 26 is formed between the first clamping member 21 and the second clamping member 25, and this clamping position 26 is used to place the handle of the toothbrush; the adjusting component 3 includes a movable member 31, an adapter 32, and a first adjusting rod 33. The movable member 31 is installed on the second end of the first clamping member 21, the adapter 32 is sleeved on the outside of the first adjusting rod 33, and is threadedly matched with the first adjusting rod 33 in the second direction, and there is a movable gap between the adapter 32 and the movable member 31 or between the first clamping member 21 and the supporting component 1; the adapter 32 is installed in the movable member 31 and at least partially abuts against the movable member 31. In this embodiment, the first direction is the rotation direction of the clamping assembly 2 and the supporting assembly 1 , and the second direction is the rotation direction of the first adjusting rod 33 .

[0049] Specifically, the first adjusting rod 33 is driven to rotate in the second direction, and a threaded fit occurs between the first adjusting rod 33 and the adapter 32. Since the adapter 32 is disposed in the movable member 31, the adapter 32 is restricted in the movable member 31 and cannot rotate along with the first adjusting rod 33. A force is generated between the adapter 32 and the movable member 31, and the adapter 32 drives the movable member 31 to move along the length direction of the first adjusting rod 33. Since the movable member 31 is mounted on the first clamping member 21, the first clamping member 21 rotates with the support assembly 1, and the adapter 32 is fixed to the movable member 31. There is an active gap between 2 and the movable member 31. When the adapter 32 moves, it pushes the movable member 31 to gradually translate upward to the maximum range, or gradually translate downward to the maximum range. Such a moving path moves in an arc, so that the movable member 31 is rotated and adjusted, and the clamping assembly 2 is driven to rotate and adjust, so as to adjust the inclination angle of the toothbrush on the clamping assembly 2. The inclination angle is set according to the size of the active gap, and the adjustment range has certain limitations; however, the angle range required for adjusting the toothbrush is small, so the structure of the adjusting assembly 3 is more consistent with the clamping assembly 2.

[0050] Preferably, when there is a movable gap at the rotating fitting point between the first clamping member 21 and the supporting assembly 1, the first clamping member 21 can move up and down at the rotating point, and when the movable member 31 is driven by the adapter 32 to move in a straight line, it can drive the first clamping member 21 to move up and down, so that the first clamping member 21 rotates around the supporting assembly 1, thereby realizing the clamping assembly 2 to adjust the rotation angle of the toothbrush.

[0051] In some embodiments, Figure 2As shown, the movable part 31 has a first movable hole 311 and a mounting cavity 312, the first clamping part 21 or the supporting component 1 has a second movable hole 211, the first movable hole 311 is for the first adjusting rod 33 to pass through, the mounting cavity 312 is used to accommodate the adapter 32, the first movable hole 311 is connected to the mounting cavity 312, and the inner diameter of the first movable hole 311 is larger than the outer diameter of the first adjusting rod 33; the clamping component 2 has a rotating shaft 27, the rotating shaft 27 is at least partially arranged in the second movable hole 211, the first clamping part 21 is rotatably matched with the supporting component 1 through the rotating shaft 27, and the inner diameter of the second movable hole 211 is larger than the outer diameter of the rotating shaft 27; a movable gap is formed between the inner wall of the first movable hole 311 and the outer wall of the first adjusting rod 33, and between the inner wall of the second movable hole 211 and the rotating shaft 27. Specifically, a first movable hole 311 or a second movable hole 211 is set, and the adapter 32 drives the movable part 31 to move to avoid interference between the movable part 31 and the adapter 32; the movable part 31 has a certain adjustment space on the first adjusting rod 33, and the first clamping part 21 has a certain adjustment space on the rotating shaft 27. When the adapter 32 moves on the first adjusting rod 33 and drives the movable part 31 and the first clamping part 21 to move left and right, the movable part 31 can move up and down on the first adjusting rod 33, so that the movable part 31 is driven by the adapter 32 to rotate in an arc along the length direction of the first adjusting rod 33, and further realizes that the movable part 31 drives the first clamping part 21 to rotate and adjust the toothbrush on the clamping position 26, so that when the toothbrush is matched with the tooth model 61, it is ensured that the toothbrush is in close contact with the tooth model 61. The angle adjustment of the clamping assembly 2 can be used to meet the needs of some toothbrushes with inclined brush heads, thereby improving the adaptability of the clamping assembly 2 in the simulated toothbrushing experimental device 200.

[0052] Preferably, Figure 3 As shown, the adapter 32 includes a moving part 322 and a limiting part 321. The limiting part 321 is installed on the moving part 322. The moving part 322 is installed in the mounting cavity 312 of the movable part 31. The moving part 322 has a threaded hole 323 for the first adjusting rod 33 to pass through. The outer wall of the first adjusting rod 33 is threadedly connected to the inner wall of the moving part 322. The limiting part 321 is at least partially arranged in the movable part 31 and abuts against the inner wall of the movable part 31. Specifically, the movable portion 322 is used to threadably cooperate with the first adjusting rod 33, and the limiting portion 321 is used to abut against the inner wall of the movable part 31. When the first adjusting rod 33 rotates, the first adjusting rod 33 drives the movable portion 322 to rotate, but the movable portion 322 cannot rotate due to the limiting portion 321, so that friction force is generated between the outer wall of the first adjusting rod 33 and the inner wall of the movable portion 322, and the friction force drives the movable portion 322 to move along the length direction of the first adjusting rod 33, so that the movable portion 322 drives the movable part 31 to move.

[0053] In some embodiments, Figure 2As shown, the support assembly 1 has an arc groove, the adjustment assembly 3 has a spherical portion 331, the first end of the first adjustment rod 33 passes through the movable member 31 and the adapter 32 in sequence, and is fixed to the spherical portion 331, and the spherical portion 331 is rotationally matched with the arc groove. Specifically, the spherical portion 331 of the first adjustment rod 33 is rotationally matched with the arc groove of the support assembly 1, and the arc groove limits the first adjustment rod 33 from moving in the lateral direction of the movable member 31, preventing the first adjustment rod 33 from moving out of the first movable hole 311, and improving the stability of the first adjustment rod 33 rotating in the first movable hole 311. Moreover, the arc groove will not affect the rotation of the first adjustment rod 33 in the second direction.

[0054] In some embodiments, Figure 1 As shown, the clamping assembly 2 also has a first support plate 22, a guide rod 24, and a second adjusting rod 23. The first support plate 22 is installed on the first clamping member 21. The first support plate 22 is provided with a first through hole 221 and a second through hole. The first end of the guide rod 24 passes through the first through hole 221 and is fixed on the second clamping member 25. The guide rod 24 is slidably matched with the first support plate 22; the first end of the second adjusting rod 23 passes through the second through hole and is abutted against the second clamping member 25. The second adjusting rod 23 is threadedly matched with the first support plate 22. Specifically, when the second adjustment rod 23 rotates in the second direction, the outer wall of the second adjustment rod 23 is threadedly engaged with the second through hole of the first support plate 22. Since the first end of the guide rod 24 passes through the first through hole 221 and is installed on the second clamping member 25, the guide rod 24 cooperates with the first support plate 22 to limit the rotation of the second adjustment rod 23. The force generated between the second adjustment rod 23 and the first support plate 22 pushes the second adjustment rod 23 forward or backward, and pushes the second clamping member 25 to move toward or away from the clamping position 26, thereby adjusting the size of the clamping position 26 so that the clamping position 26 can adapt to handles of toothbrushes of different sizes. Moreover, after the guide rod 24 moves to a certain distance, the second end of the guide rod 24 abuts against the first support plate 22, preventing the guide rod 24 from coming out of the first through hole 221 and limiting the moving distance of the second clamping member 25.

[0055] Preferably, Figure 1 As shown, the first clamping member 21 or the second clamping member 25 has an arc-shaped groove 28 on one side close to the clamping position 26; the first clamping member 21 or the second clamping member 25 has an elastic pad, which is installed in the arc-shaped groove 28. Specifically, by providing the elastic pad, the handle of the toothbrush is prevented from being rigidly connected to the first clamping member 21 or the second clamping member 25. When the clamping assembly 2 clamps the toothbrush, the elastic pad improves the stability of the toothbrush on the clamping position 26 and also prevents the clamping assembly 2 from squeezing and damaging the toothbrush; moreover, the first clamping member 21 and the second clamping member 25 are both provided with an arc-shaped groove 28, so that the contact surface of the first clamping member 21 and the second clamping member 25 close to the clamping position 26 fits with the outer wall of the handle, further improving the stability of the toothbrush on the clamping position 26.

[0056] In some embodiments, Figure 1 As shown, the support assembly 1 includes a first support seat 11 and a second support seat 12. The second support seat 12 is installed on the first support seat 11. The second support seat 12 has a slide groove 121. The first support plate 22 is at least partially disposed in the slide groove 121 and slidably cooperates with the slide groove 121. Specifically, the first support seat 11 is used to support the clamping assembly 2 and the movable member 31, so that the clamping assembly 2 clamps the toothbrush on the first support seat 11 and adjusts the rotation angle of the clamping assembly 2; the first support plate 22 is used to slidably cooperate with the second support seat 12 in the slide groove 121, so that the first support plate 22 drives the clamping assembly 2 to move up and down in the slide groove 121.

[0057] Preferably, Figure 4 As shown, the clamping adjustment mechanism 100 has a third adjustment rod 4, a guide block 222 is provided on one side of the first support plate 22 close to the second support seat 12, the second support seat 12 has a dovetail groove matched with the guide block 222, the guide block 222 has a thread bar 223, and the third adjustment rod 4 is rotatably installed in the second support seat 12 and threadedly matched with the thread bar 223. Specifically, when the third adjustment rod 4 rotates in the second direction, the outer wall of the third adjustment rod 4 is threadedly matched with the thread bar 223 on the first support plate 22, thereby driving the thread bar 223 to move up and down, and driving the guide block 222 to slide and match with the dovetail groove of the second support seat 12, and the dovetail groove and the guide block 222 cooperate to improve the stability of the first support plate 22 moving up and down.
