[0055] In order to facilitate the understanding of the present invention, specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.

[0056] Unless otherwise specified or defined, the "first, second..." used in this article is only used to distinguish names and does not represent a specific quantity or order.

[0057] Unless stated otherwise or defined otherwise, the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0058] It should be noted that when an element is considered to be "fixed to" another element, it can be directly fixed to the other element or there can be an intermediate element; when an element is considered to be "connected to" another element, it can be directly connected to the other element or there can be an intermediate element; when an element is considered to be "mounted on" another element, it can be directly mounted on the other element or there can be an intermediate element. When an element is considered to be "located on" another element, it can be directly located on the other element or there can be an intermediate element.

[0059] In this embodiment, in order to improve the adaptability of the sensing device 200, it is necessary to improve the flexibility of the sensing device 200 during installation and to solve the technical problem of how to adjust the sensing device 200 after installation.

[0060] To this end, the present invention also proposes an adjustment mechanism 100, such as Figures 1 to 6As shown, it includes: a support base 1, a first adjustment component 10, and a second adjustment component 20. The first adjustment component 10 includes a first adjustment member 12, a first elastic member 15, a movable ball 14, and a rotating block 13; the first end of the rotating block 13 is installed on the second adjustment component 20, and the second end of the rotating block 13 is rotatably connected to the support base 1. The rotating block 13 has a plurality of first card grooves 131 on the circumference; the first adjustment member 12 is movably installed in the support base 1 and is at least partially exposed relative to the support base 1. The first elastic member 15 is installed in the support base 1, and the first end of the first elastic member 15 is installed in the support base 1, and the first end of the first elastic member 15 is installed in the support base 1. The two ends of an elastic member 15 respectively abut against the first adjusting member 12 and the inner wall of the support seat 1; the outer wall of the first adjusting member 12 is provided with a movable groove 121, and the support seat 1 has a through hole 102, the movable groove 121 is connected with the first clamping groove 131 through the through hole 102, and the movable ball 14 is movably arranged at the through hole 102; wherein, the first adjusting member 12 has a first moving position and a second moving position, in the first moving position, the movable ball 14 cooperates with the first clamping groove 131; in the second moving position, the movable ball 14 is separated from the first clamping groove 131.

[0061] Specifically, in the first direction 300, the first adjustment assembly 10 is used to adjust the angular position of the reed sensor 210, thereby adjusting the relative position between the reed sensor 210 and the outer cover trigger 211. When the reed sensor 210 is installed on the second adjustment assembly 20, the second adjustment assembly 20 is rotatably connected to the support base 1 via the rotating block 13. The support base 1 can be used to be installed on the mounting base 212 on the original equipment. When the angle of the second adjustment assembly 20 needs to be adjusted, the first adjustment member 12 is pressed. The first adjustment member 12 drives the movable groove 121 to move and squeezes the first elastic member 15. The first elastic member 15 generates a reaction force, and the first adjustment member 12 moves from the first movable position to the second movable position. The movable ball 14 moves downward from the through hole 102, and most of it slides into the movable groove 121. At this time, the movable ball 14 is separated from the first locking groove 131. The movable ball 14 cannot restrict the rotating block 13, and the rotating block 13 can be rotated and adjusted arbitrarily on the support base 1.

[0062] When the rotating block 13 moves to the preset position and the first adjusting member 12 is released, the reaction force of the first elastic member 15 drives the first adjusting member 12 from the second movable position to the first movable position. The inner wall of the movable groove 121 guides or pushes the movable ball 14 to move, causing the movable ball 14 to move upward. The movable ball 14 is at least partially retained within the first retaining groove 131. The bottom of the movable ball 14 abuts against the movable groove 121, and the movable ball 14 limits the position of the rotating block 13, thereby achieving angular adjustment of the second adjusting assembly 20. This adjustment method accommodates clockwise or counterclockwise rotational adjustment of the reed sensor 210. Furthermore, the angle of the reed sensor 210 can be adjusted by simply pressing the first adjusting member 12. This adjustment method is reliable and stable, improving the adaptability of the reed sensor 210 after installation.

[0063] Furthermore, if Figure 6 As shown, the first adjusting member 12 has a limiting groove 122, the support seat 1 has a first mounting cavity 101, a portion of the first elastic member 15 is located in the limiting groove 122, and the other portion is located in the first mounting cavity 101, and the outer wall of the first elastic member 15 fits with the inner wall of the limiting groove 122, thereby improving the stability of the first elastic member 15 in the support seat 1.

[0064] In order to improve the adjustment stability of the first adjustment member 12. In some embodiments, as Figure 6 and Figure 7 As shown, the movable groove 121 is extended along the axial direction of the first adjusting member 12, and the movable groove 121 includes a receiving groove 1211 and a guide groove 1212. The receiving groove 1211 is connected to the first end of the guide groove 1212, and the second end of the guide groove 1212 is connected to the through hole 102. The depth of the receiving groove 1211 is greater than the depth of the guide groove 1212; the guide groove 1212 has a guide surface 1213 that fits with the movable ball 14.

[0065] Specifically, since the depth of the accommodating groove 1211 is greater than the depth of the guide groove 1212, when the first adjusting member 12 is in the first moving position, the bottom of the moving ball 14 is located in the guide groove 1212, the middle of the moving ball 14 is located at the through hole 102, and the top of the moving ball 14 is located in the first clamping groove 131. When the first adjusting member 12 is in the first moving position, the moving ball 14 is engaged with the first clamping groove 131, limiting the rotation of the rotating block 13. When the first adjusting member 12 is in the second moving position, the bottom of the moving ball 14 moves into the accommodating groove 1211, and the top of the moving ball 14 moves from the first slot 131 to the through hole 102. The moving ball 14 is separated from the first slot 131, and the rotating block 13 can be rotated and adjusted at will. When the rotating block 13 is adjusted to the preset position, the first adjusting member 12 is released, and the first adjusting member 12 is moved to the first moving position through the first elastic member 15, so that the moving ball 14 cooperates with the first slot 131 to fix the rotating block 13.

[0066] Moreover, the extension and contraction direction of the first elastic member 15 intersects with the moving direction of the movable ball 14. The pressure of the movable ball 14 acts on the bottom wall of the guide groove 1212, and the first elastic member 15 will apply a tangential force to the movable ball 14. In the absence of external force, the movable ball 14 cannot squeeze the first adjusting member 12 to move. Only when the first adjusting member 12 moves can the position of the movable ball 14 be adjusted to achieve the engagement or separation of the movable ball 14 and the first slot 131. Therefore, the adjustment stability of the first adjusting member 12 is relatively high.

[0067] Preferably, Figure 6 As shown, the length of the receiving groove 1211 is less than or equal to the exposed length of the first adjusting member 12; when the first adjusting member 12 is in the first moving position, the first end of the moving ball 14 is located in the guide groove 1212, and the second end of the moving ball 14 is engaged with the first engaging groove 131; when the first adjusting member 12 is in the second moving position, the first end of the moving ball 14 is located in the receiving groove 1211, and the second end of the moving ball 14 is separated from the first engaging groove 131. Specifically, because the length of the receiving groove 1211 is less than the exposed length of the first adjusting member 12, when the first adjusting member 12 is squeezed and moved by a finger, the first adjusting member 12 moves toward the inside of the support base 1. The first adjusting member 12 does not need to be fully moved into the support base 1, and the moving ball 14 can move into the receiving groove 1211 through the guide groove 1212, thereby separating the moving ball 14 from the first engaging groove 131, thereby improving the adjustment convenience of the first adjusting member 12.

[0068] Preferably, Figure 7 As shown, the depth of the guide groove 1212 gradually decreases from the first end to the other end of the guide groove 1212, and the bottom wall of the guide groove 1212 forms a guide surface 1213. Specifically, when the first adjusting member 12 switches between the first moving position and the second moving position, the movable ball 14 moves between the receiving groove 1211 and the guide groove 1212. The guide surface 1213 is used to guide the movement of the movable ball 14, thereby improving the passability of the movable ball 14 and further improving the stability of the movable ball 14 engaging or disengaging with the first engaging groove 131.

[0069] In order to improve the stability of the rotational cooperation between the rotating block 13 and the supporting seat 1. In some embodiments, Figure 2 and Figure 6As shown, the first adjusting component 10 also has a first pin shaft 11 and a compression spring 111. The support seat 1 has two support blocks 103, and the two support blocks 103 are arranged opposite to each other. The first end of the first pin shaft 11 passes through one of the support blocks 103 and is threadedly engaged with the other support block 103. The second end of the first pin shaft 11 is against one of the support blocks 103; the rotating block 13 is sleeved on the outside of the first pin shaft 11, and the compression spring 111 is arranged between the inner wall of the rotating block 13 and the outer wall of the first pin shaft 11, and the two ends of the compression spring 111 are respectively fixed to the rotating block 13 and the first pin shaft 11.

[0070] Specifically, the rotating block 13 is sleeved onto the outside of the first pin 11, the first end of the first pin 11 is threadedly engaged with another support block 103, and the second end thereof abuts against one of the support blocks 103. The support base 1 and the rotating block 13 are assembled using the first pin 11, so that the rotating block 13 is rotatably connected to the support base 1. Furthermore, the two support blocks 103 support the two ends of the first pin 11, while the middle portion of the first pin 11 is rotatably connected to the rotating block 13, thereby improving the stability of the rotational connection between the support base 1 and the rotating block 13.

[0071] In addition, the main function of the compression spring 111 is to leave a gap between the rotating block 13 and the support seat 1 parts. During assembly, the compression spring 111 is used for initial pre-tightening to facilitate the first pin shaft 11 to be nailed and fixed.

[0072] In order to further improve the adaptability of the reed sensor 210. In some embodiments, Figure 1 、 Figures 8 to 10 As shown, the second adjusting assembly 20 includes a first movable seat 2, a second adjusting member 21, and a first movable member 25. The rotating block 13 is installed on the first movable member 25. The first movable seat 2 has a second mounting cavity 201. The first movable member 25 is movably arranged in the second mounting cavity 201 of the first movable seat 2. The second adjusting member 21 is movably arranged on the first movable member 25 and is at least partially exposed relative to the first movable seat 2. The moving direction of the second adjusting member 21 intersects with the moving direction of the first movable member 25. The second adjusting member 21 has a third moving position and a fourth moving position. In the third moving position, the first movable member 25 is engaged with the first movable seat 2. In the fourth moving position, the first movable member 25 slides with the first movable seat 2.

[0073] Specifically, the reed sensor 210 can be mounted on the first movable base 2. When the second adjusting member 21 is pressed, the second adjusting member 21 moves from the third movable position to the fourth movable position. The first movable member 25 can slide and cooperate with the first movable base 2 to adjust the relative position between the first movable member 25 and the first movable base 2 in the second direction 400. Since the first movable member 25 is fixed to the rotating block 13, when the first movable base 2 moves, the position of the reed sensor 210 is adjusted, thereby improving the adaptability of the reed sensor 210. When the first movable base 2 moves to the preset position and the second adjusting member 21 moves to the third movable position, the first movable member 25 engages with the first movable base 2, thereby fixing the position of the first movable base 2 and improving the stability of the first movable base 2 after adjustment.

[0074] Moreover, the second adjusting member 21 is exposed relative to the first movable seat 2 , and the relative position between the first movable seat 2 and the first movable member 25 can be adjusted by pressing the second adjusting member 21 with a finger, which greatly improves the convenience of the second adjusting component 20 .

[0075] In order to further adjust the position of the first movable seat 2. Preferably, as Figure 10 As shown, the second adjustment component 20 also includes a second elastic member 22, a third elastic member 24, and a first limiting column 23; the first moving member 25 has a third mounting cavity 251, the first side wall of the first moving seat 2 has at least two limiting holes 202, and the side wall of the second adjusting member 21 has a receiving groove 211, which corresponds to any one of the limiting holes 202; the second elastic member 22 is installed in the third mounting cavity 251 of the first moving member 25, and the two ends of the second elastic member 22 are respectively aligned with the ends of the second adjusting member 21. The bottom end is against the inner wall of the first movable member 25; the third elastic member 24 is sleeved on the outside of the first limiting column 23, and the two ends of the third elastic member 24 are respectively against the first end of the first limiting column 23 and the inner wall of the first movable member 25; wherein, the elastic direction of the third elastic member 24 intersects with the elastic direction of the second elastic member 22; the first limiting column 23 is movably installed in the first movable member 25, and the first end of the first limiting column 23 is used to cooperate with any one of the limiting holes 202, and the second end of the first limiting column 23 is used to cooperate with the accommodating groove 211.

[0076] Specifically, when the second adjusting member 21 moves from the third moving position to the fourth moving position, the second adjusting member 21 squeezes the second elastic member 22, and at the same time, the accommodating groove 211 on the outer wall of the second adjusting member 21 moves downward and moves to a position corresponding to the first limiting column 23. The force of the third elastic member 24 pushes the second end of the first limiting column 23 to move into the accommodating groove 211, and the first end of the first limiting column 23 is separated from the limiting hole 202, so that the first moving member 25 and the first moving seat 2 can slide with each other, thereby adjusting the moving position of the first moving seat 2. When the first movable seat 2 moves to the preset position, the second adjusting member 21 is released, and the second adjusting member 21 is subjected to the reaction force of the second elastic member 22, thereby driving the second adjusting member 21 to move to the third movable position, and the accommodating groove 211 moves with the second adjusting member 21, and the inner wall of the accommodating groove 211 squeezes the first limiting column 23, and the second end of the first limiting column 23 has an outer arc surface, which facilitates the first limiting column 23 to move toward the limiting hole 202, so that the first end of the first limiting column 23 is engaged with the limiting hole 202, thereby fixing the first movable seat 2 and the first movable member 25.

[0077] In order to further improve the stability of the cooperation between the first moving member 25 and the first moving seat 2. Preferably, Figure 1 、 Figure 10 As shown, the two limiting holes 202 are the first group of limiting holes 202, and the second side wall of the first movable seat 2 is provided with a second group of limiting holes 202, and the first group of limiting holes 202 is arranged opposite to the second group of limiting holes 202; the second adjusting member 21 has two accommodating grooves 211, and the two accommodating grooves 211 are arranged opposite to each other; the number of the first limiting columns 23, the number of the third elastics 24, and the number of the accommodating grooves 211 correspond to each other; the openings of the two accommodating grooves 211 are arranged in a divergent manner, and the opening direction of the accommodating groove 211 is toward the second end of the first limiting column 23. Specifically, when the second adjusting member 21 is pressed to move, the second adjusting member 21 drives the accommodating grooves 211 on both sides to move downward. When the accommodating grooves 211 move to the position corresponding to the two first limiting columns 23, the two first limiting columns 23 are close to one end of the accommodating grooves 211, and are at least partially driven into the accommodating grooves 211 by the reaction force of the third elastic member 24. The two first limiting columns 23 are respectively separated from the limiting holes 202 on both sides of the first moving seat 2, and the first moving seat 2 slides with the first moving member 25. After adjusting the position of the first moving seat 2, the second adjusting member 21 is released, and the second adjusting member 21 is driven to the third moving position by the reaction force of the second elastic member 22. The bottom walls of the two accommodating grooves 211 respectively squeeze the two first limiting columns 23, so that the two first limiting columns 23 respectively cooperate with the limiting holes 202 on both sides of the first moving seat 2, thereby limiting the movement between the first moving seat 2 and the first moving member 25.

[0078] In order to improve the sliding stability between the first movable seat 2 and the first movable member 25. Preferably, Figure 1 and Figure 10 As shown, the second adjustment assembly 20 further includes a guide block 26, which is mounted on the first movable member 25. The first movable base 2 is provided with at least two first guide grooves 203, each extending along the moving direction of the first movable member 25. The second adjustment member 21 is at least partially located within one of the first guide grooves 203, and the guide block 26 is at least partially located within the other first guide groove 203. Specifically, one of the first guide grooves 203 is used to allow the second adjustment member 21 to avoid sliding between the first movable base 2 and the first movable member 25; the other first guide groove 203 is used to allow the guide block 26 to move. The guide block 26 is mounted on the first movable member 25, thereby limiting the moving direction between the first movable member 25 and the first movable base 2, thereby improving the stability of the first movable base 2 in the second direction 400.

[0079] Example 2

[0080] The present invention proposes a sensing device 200, such as Figure 1 、 Figure 11 、 Figure 12 As shown, it includes a reed sensor 210, an outer cover trigger 211, a mounting base 212, and an adjustment mechanism 100. The adjustment mechanism 100 includes a first adjustment component 10, a second adjustment component 20, and a third adjustment component 30. In the first direction 300, the first end of the first adjustment component 10 rotates with the support base 1; in the second direction 400, the first end of the second adjustment component 20 slides with the second end of the first adjustment component 10; in the third direction 500, the third adjustment component 30 slides with the second end of the second adjustment component 20; wherein, the first direction 300 is clockwise or counterclockwise, the second direction 400 and the third direction 500 are linear directions, and the second direction 400 intersects with the third direction 500. The outer cover trigger 211 is rotatably mounted on the mounting base 212. The first adjustment assembly 10 is mounted on the mounting base 212 via the support base 1. The reed sensor 210 is mounted on the third adjustment assembly 30. The reed sensor 210 is disposed circumferentially around the outer cover trigger 211. The outer cover trigger 211 has a magnet, and the reed sensor 210 inductively cooperates with the magnet.

[0081] Specifically, the first adjustment assembly 10 is used to adjust the position of the reed sensor 210 in a first direction 300, the second adjustment assembly 20 is used to adjust the position of the reed sensor 210 in a second direction 400, and the third adjustment assembly 30 is used to adjust the position of the reed sensor 210 in a third direction 500. During installation, the magnet can be placed on the inner wall of the outer cover trigger 211, while the reed sensor 210 is positioned circumferentially around the outer cover trigger 211 via the adjustment mechanism 100. This eliminates the need to disassemble the original equipment. When the position between the reed sensor 210 and the magnet needs to be adjusted, any one or more of the first adjustment assembly 10, the second adjustment assembly 20, and the third adjustment assembly 30 can be selectively used for adjustment. Furthermore, the adjustment method of the adjustment mechanism 100 is relatively simple, improving operational convenience.

[0082] When the outer cover trigger 211 rotates, the magnet of the outer cover trigger 211 approaches the reed sensor 210 and is inductively coupled with the reed sensor 210. The reed sensor 210 generates an electrical signal and sends it to a receiving device. The operator detects the position status information of the outer cover trigger 211 through the receiving device.

[0083] When installing the first adjustment assembly 10, Figure 1 、 Figure 2 、 Figure 3 、 Figure 12 As shown, the adjustment mechanism 100 also has a fastener 16, a first support plate 17, a clamping plate 18, and a second support plate. The first support plate 17 is fixed to the support base 1 and is arranged on both sides of the support base 1. The second support plate has a through groove and a fixing hole. The second support plate is fixed to the mounting base 212 by screws. The through groove is extended along the circumference of the second support plate. The first end of the fastener 16 passes through the first support plate 17 and the through groove and is threadedly connected to the clamping plate 18. The second end of the fastener 16 is against the first support plate 17. The fastener 16 is adjusted so that the second end of the fastener 16 and the clamping plate 18 squeeze the first support plate 17, thereby fixing the first support plate 17 to the second support plate and improving the stability and flexibility of the support base 1 on the mounting base 212.

[0084] In this embodiment, the first adjustment component 10 and the second adjustment component 20 adjust the position of the reed sensor 210 in the first direction 300 and the second direction 400 respectively. The first adjustment component 10 and the second adjustment component 20 have been described in detail in the first embodiment and will not be repeated here.

[0085] In order to adjust the position of the reed sensor 210 in the third direction 500. In some embodiments, Figure 9As shown, the third adjustment component 30 includes a second movable seat 3, a second movable member 34, and a third adjustment member 31. The outer wall of the second movable seat 3 has a plurality of second card grooves 301, and the plurality of second card grooves 301 are distributed along the length direction of the second movable seat 3; the second movable member 34 is movably arranged in the first movable seat 2 of the second adjustment component 20, and is slidably connected to the inner wall of the first movable seat 2, and the second movable member 34 has a first card block 341 that cooperates with the second card groove 301; the third adjustment member 31 is movably arranged in the first movable seat 2, and is at least partially exposed relative to the first movable seat 2, and the third adjustment member 31 is used to adjust the first card block 341 to cooperate with any one of the second card grooves 301.

[0086] Specifically, press the third adjusting member 31 to unlock the second moving member 34, and the third adjusting member 31 pushes the second moving member 34; when the second moving seat 3 is moving, the second moving seat 3 pushes the second moving member 34 to move in the first moving seat 2, and the second moving seat 3 moves to a preset position, release the third adjusting member 31, the third adjusting member 31 is reset, and the second moving member 34 is locked, and the second moving member 34 cannot move, the first card block 341 is engaged with the second card slot 301, and the first card block 341 limits the movement of the second moving seat 3, so that the position of the second moving seat 3 is adjusted in the third direction 500, and the reed sensor 210 is installed in the second moving seat 3 to adjust the position of the reed sensor 210 in the third direction 500.

[0087] Preferably, Figure 9 As shown, the third adjustment component 30 also includes a second limiting column 32, a fourth elastic member 33, and a fifth elastic member 35. The second movable member 34 has a limiting chamber 342. The fourth elastic member 33 is installed in the limiting chamber 342, and the second limiting column 32 is at least partially arranged in the limiting chamber 342 and slides with the inner wall of the second movable member 34. The two ends of the fourth elastic member 33 respectively abut the first end of the second limiting column 32 and the inner wall of the second movable member 34; the third adjusting member 31 is used to abut the second end of the second limiting column 32; the first movable seat 2 has a first active cavity 204, the second movable member 34 is arranged in the first active cavity 204, the fifth elastic member 35 is installed in the first active cavity 204, and the two ends of the fifth elastic member 35 respectively abut the second movable member 34 and the inner wall of the first movable seat 2, and the elastic force directions of the fourth elastic member 33 and the fifth elastic member 35 intersect; there is a movable gap 38 between the second movable member 34 and the inner wall of the first movable seat 2.

[0088] Specifically, when the third adjusting member 31 is pressed, the third adjusting member 31 pushes the second limiting column 32 to move, the second limiting column 32 squeezes the fourth elastic member 33, and the second limiting column 32 moves completely into the limiting chamber 342, and the second moving member 34 is completely separated from the first moving seat 2, and the second moving member 34 has space to move in the first moving seat 2; and there is a movable gap 38 between the second moving member 34 and the inner wall of the first moving seat 2. When the second moving seat 3 moves in the first moving seat 2, the second moving seat 3 pushes the second moving member 34 to move through the first blocking block 341, so that the second moving member 34 moves at least partially to the movable gap 38, and the second moving member 34 squeezes the fifth elastic member 35 when moving, and the fifth elastic member 35 generates a reaction force, so that the first blocking block 341 always cooperates with any one of the second slots 301. After the force of pressing the third adjusting member 31 disappears, the fifth elastic member 35 drives the second movable member 34 to reset. At the same time, the reaction force generated by the fourth elastic member 33 drives the second limiting column 32 to move toward the third adjusting member 31. The second limiting column 32 moves at least partially into the second active cavity 205. The second limiting column 32 limits the second movable member 34 from moving in the first active cavity 204, so that the first blocking block 341 engages with the second slot 301, and limits the second movable seat 3 from moving in the first movable seat 2.

[0089] Preferably, Figure 9 As shown, the third adjustment component 30 also includes a third limiting column 39, the first movable seat 2 also has a second movable cavity 205, and the third limiting column 39 is installed in the second movable cavity 205; the third adjustment member 31 is provided with a second guide groove 311, and the third limiting column 39 is at least partially arranged in the second guide groove 311; the second guide groove 311 extends along the moving direction of the third adjustment member 31, and the third limiting column 39 is used to abut against the inner wall of the third adjustment member 31. Specifically, by setting a second active cavity 205 in the first movable seat 2, and setting the third limiting column 39 in the second active cavity 205, the third limiting column 39 is set in the second guide groove 311, and the third limiting column 39 limits the moving distance of the third adjusting member 31, thereby improving the movement stability of the third adjusting member 31. Moreover, when the position of the third adjusting member 31 is fixed, the second limiting column 32 will also be under the action of the fourth elastic member 33. The first end of the second limiting column 32 is located in the limiting cavity 342, and the second end of the second limiting column 32 is located in the second active cavity 205, thereby limiting the movement of the second movable member 34.

[0090] In some embodiments, as Figure 9As shown, the third adjustment assembly 30 also includes a sixth elastic member 37 and a second clamping block 36. The sixth elastic member 37 is installed in the first movable seat 2. The two ends of the sixth elastic member 37 are respectively against the first end of the second clamping block 36 and the inner wall of the first movable seat 2. The second end of the second clamping block 36 is used to cooperate with any one of the second clamping slots 301. Specifically, when the second movable seat 3 moves in the first movable seat 2, the second clamping slot 301 of the second movable seat 3 will produce a clicking sound with the second clamping block 36. This is because when the second movable seat 3 moves, the inner wall of the second movable seat 3 squeezes the second clamping block 36, and the second clamping block 36 squeezes the sixth elastic member 37. The reaction force of the sixth elastic member 37 drives the second clamping block 36 to collide with the bottom wall of the second clamping slot 301, forming a clicking sound. This collision sound can remind the user that the second movable seat 3 has adjusted several distance gears on the first movable seat 2, thereby further improving the convenience of the second movable seat 3 when adjusting.
