Musical instrument stand

Abstract

The invention provides a musical instrument stand, comprising: a connecting frame, a bracket arm group and a positioning mechanism. The bracket arm group is connected to the connecting frame to form a clamping area for clamping a musical instrument, and a movable bracket arm of bracket arm group can move along a moving axis to expand or shrink the clamping area. The positioning mechanism is disposed on the connecting frame, and an actuating member of the positioning mechanism is moved along a brake axis, so that a movable member of the positioning mechanism can be separated from the movable bracket arm, and thus the movable bracket arm is allowed to move freely relative to the connecting frame. Then a returning member of the positioning mechanism can drive the movable member to contact the movable bracket arm, thereby making the movable bracket arm unable to move. Therefore, the movable bracket arm cooperates with the positioning mechanism to flexibly adjust the size of the clamping area, so that musical instruments of various contour sizes can be clamped by the bracket arm group, thereby increasing the practicality of the musical instrument stand.

Description

Technical Field

[0001] The present invention relates to a musical instrument frame that can be clamped to a musical instrument, and more particularly to a musical instrument frame that can change the size of the clamping area R according to the outline of the musical instrument frame, so that the musical instrument frame can be clamped to musical instruments of various sizes and outlines. Prior Technology

[0002] A drum set is a comprehensive instrument composed of various drums and percussion instruments with different timbres. Common components of a drum set include: bass drum, snare drum, tambourine, floor drum, alto cymbals, pedal cymbals, and bass drum pedal. Among them, the snare drum plays a crucial role in drumming due to its unique timbre and playing techniques. To ensure the stability of the snare drum during playing, most snare drums are used with a drum stand. The drum stand is mainly used to fix the snare drum in place by clamping it, thus preventing the snare drum from shifting when it is struck.

[0003] However, the common drum stands currently available on the market generally have size limitations, which means that they can usually only clamp a specific size of small drum. This makes them unsuitable for small drums of various sizes. Therefore, when a drummer needs to change to a different size small drum, the original drum stand may not be able to clamp the other small drum. Consequently, the drummer must purchase a drum stand that fits the size of the other small drum, which not only makes the drum stand inconvenient to use but also increases additional costs. Summary of the Invention

[0004] The main purpose of this invention is to improve the structural design of the instrument rack, which can clamp instruments of various sizes and shapes, thereby increasing the practicality of the instrument rack.

[0005] The secondary objective of this invention is to improve the structural design of the limiting mechanism, so that users can easily operate the improved limiting mechanism to adjust the outline size of the clamping area of ​​the bracket arm assembly.

[0006] To achieve the aforementioned objectives, the present invention provides a musical instrument stand, which can be used with a musical instrument and includes: a connecting frame, a bracket arm assembly, and a limiting mechanism.

[0007] The aforementioned bracket arm assembly has a plurality of bracket arms connected to the aforementioned connecting frame, and the plurality of aforementioned bracket arms constitute a clamping area capable of clamping the aforementioned musical instrument. One of the aforementioned bracket arms is configured as a movable bracket arm movably connected to the aforementioned connecting frame. The movable bracket arm can move along a moving axis to expand or shrink the aforementioned clamping area.

[0008] The aforementioned limiting mechanism is disposed on the aforementioned connecting frame and has a movable member and a return member. The movable member is movably connected to the aforementioned connecting frame, so that the movable member can move along a brake axis intersecting the aforementioned moving axis. Consequently, the movable member can move back and forth between a separation position separate from the aforementioned movable bracket arm and a contact position contacting the aforementioned movable bracket arm. The aforementioned return member can drive the movable member to move to the aforementioned contact position, preventing the aforementioned movable bracket arm from moving relative to the aforementioned connecting frame.

[0009] The movable member has an actuating element and a brake pad. The actuating element is operated to move the movable member to the separation position, so that the brake pad can separate from the movable bracket arm. When the movable member is in the contact position, the brake pad can contact the movable bracket arm.

[0010] In one embodiment, the movable member further includes a linkage member for moving the actuating member and the brake pad in the same direction along the brake axis. The two ends of the linkage member are respectively connected to the actuating member and the brake pad, forming a receiving channel between the actuating member, the brake pad, and the linkage member. The actuating member is located on one side of the movable bracket arm, and the brake pad is located on the other side of the movable bracket arm, allowing the movable bracket arm to pass through the receiving channel, with a portion of the movable bracket arm located inside the receiving channel. The two ends of the return member respectively contact the linkage member and the connecting frame.

[0011] In another embodiment, both the actuating member and the brake pad are located on the same side of the movable bracket arm, while the resetting member is located inside the receiving channel and contacts the linkage member and the connecting frame at both ends, respectively.

[0012] In another embodiment, the movable member further includes a linkage member for enabling the starter and brake pads to move in opposite directions along the brake axis. This allows the starter to move along a first direction of the brake axis, while the brake pads move along a second direction of the brake axis, with the first direction being opposite to the second direction. The linkage member includes a linkage gear pivotally connected to the connecting frame, a starting rack connected to the starter, and a contact rack connected to the brake pads. The starting rack and the contact rack mesh with opposite sides of the linkage gear, so that when the starter moves along the first direction of the brake axis, the starting rack drives the linkage gear to rotate, and the contact rack moves along the second direction of the brake axis through the rotating linkage gear.

[0013] In another embodiment, the linkage includes: a linkage rod, a starting protrusion, and a contact protrusion. The linkage rod is pivotally connected to the connecting frame and has a starting slot and a contact slot formed at both ends, respectively. The starting protrusion is formed on the starting member and can be inserted into the starting slot. The contact protrusion is formed on the brake pad and can be inserted into the contact slot.

[0014] The aforementioned activator drives the aforementioned activating protrusion to move along the first direction of the aforementioned brake axis, causing the activating protrusion to move inside the aforementioned activating slot, thereby causing the aforementioned linkage rod to swing, thereby changing the relative position between the aforementioned contact protrusion and the contact slot, so that the aforementioned contact protrusion can drive the aforementioned brake pad to move along the second direction of the aforementioned brake axis.

[0015] In the final embodiment, the limiting mechanism further includes a linkage that can convert linear motion into rotational motion. The linkage is connected between the actuating member and the brake pad, so that when the actuating member moves along the brake axis, the linkage can cause the brake pad to swing closer to or further away from the movable bracket arm. In this embodiment, the linkage includes: a moving rod, a rotating disk, and a swing rod. The moving rod is connected to the actuating member and has a longitudinal slot. The rotating disk is pivotally connected to the connecting frame and has a disk protrusion that can pass through the longitudinal slot. The swing rod is connected between the brake pad and the rotating disk. The movement of the actuating member along the brake axis can change the relative position between the disk protrusion and the longitudinal slot, causing the rotating disk to rotate. Consequently, the swing rod can cause the brake pad to swing closer to or further away from the movable bracket arm.

[0016] In the foregoing embodiment, the connecting frame has a connecting space inside to accommodate the limiting mechanism actuator and brake pad, and has two bracket through holes communicating with the connecting space. The connecting space through which the movable bracket arm can pass allows the movable bracket arm to form an inner section located inside the connecting space and two exposed sections protruding from the bracket through holes. The inner section is located between the two exposed sections, and each of the exposed sections is located outside the connecting space and protrudes to form an anti-detachment block. The two anti-detachment blocks can contact the connecting frame during the movement of the movable bracket arm along the moving axis to prevent the movable bracket arm from separating from the connecting frame.

[0017] Furthermore, the connecting frame has two positioning surfaces spaced apart from each other inside the connecting space, and a linkage connecting the starter and the brake pad is located between the two positioning surfaces. When the starter can move along the brake axis, the linkage can contact one of the positioning surfaces to limit the movement distance of the starter inside the connecting space. The connecting frame further has a positioning space located below the connecting space, and the positioning surfaces are formed on opposite sides of the positioning space, so that a part of the linkage is located inside the positioning space.

[0018] Furthermore, the aforementioned connecting frame has a first connecting portion that can connect the aforementioned bracket arm assembly and a second connecting portion formed on one side of the aforementioned first connecting portion. The transverse cross-sectional profile of the aforementioned first connecting portion is larger than the transverse cross-sectional profile of the aforementioned second connecting portion, such that the aforementioned connecting frame forms an exposed space between the aforementioned first connecting portion and the aforementioned second connecting portion. The aforementioned second connecting portion is connected to a bracket via a tilt adjuster that can change the angle of the aforementioned connecting frame, and the aforementioned tilt adjuster is located inside the aforementioned exposed space.

[0019] In a preferred embodiment, the connecting frame has a connecting body and a covering body. The connecting body has a recess, a connecting arm formed in the recess, and a pivot rod connected to the connecting arm. The covering body is connected to the recess, such that the covering body and the recess together form the first connecting portion. The pivot rod is pivotally connected to the tilt adjuster, such that the connecting arm is adjacent to the tilt adjuster. Thus, the connecting arm and the pivot rod together form the second connecting portion.

[0020] The invention is characterized by the movable member of the limiting mechanism moving along the brake axis, causing the movable member to move to the separation position, allowing it to separate from the movable bracket arm of the bracket arm assembly. This allows the movable bracket arm to move along the moving axis to expand or shrink the clamping area. Furthermore, the return member of the limiting mechanism can drive the movable member to the contact position, causing it to contact the movable bracket arm to generate friction, thereby preventing the movable bracket arm from moving relative to the connecting frame and fixing the size of the clamping area. Thus, the movable bracket arm, in conjunction with the limiting mechanism, can flexibly and steplessly adjust the size of the clamping area, allowing instruments of various sizes and profiles to be clamped by the bracket arm assembly, thereby increasing the practicality of the instrument rack.

[0021] Furthermore, the movable part of the limiting mechanism can move along the brake axis, allowing the user to press or pull the movable part from the contact position to the separation position. This allows the movable bracket arm to move along the movement axis to expand or shrink the clamping area. When the user releases the movable part, the return part of the limiting mechanism can drive the movable part to the contact position, causing the movable part to contact the movable bracket arm to generate friction, thereby preventing the movable bracket arm from moving relative to the connecting frame and fixing the size of the clamping area. In this way, the limiting mechanism can be easily operated by the user to adjust the outline size of the clamping area of ​​the bracket arm assembly. Simple Explanation of the Diagram

Implementation

[0023] To facilitate a deeper and more detailed understanding of the structure, use, and features of the present invention, preferred embodiments are described below in conjunction with the accompanying drawings:

[0024] Please refer to Figures 1 and 2. In the first preferred embodiment, the instrument stand 1 of the present invention can be used with an instrument (such as a snare drum). The instrument stand 1 is mainly composed of a bracket 10, a support leg 20, a tilt adjuster 30, a connecting frame 40, a bracket arm assembly 50, and a limiting mechanism 60. The two ends of the bracket 10 are respectively connected to the support leg 20 and the tilt adjuster 30. The support leg 20 has a fixed sleeve 21, a movable sleeve 22, a leg locking member 23, a plurality of leg legs 24, and a plurality of connecting arms 25. The rod 25 consists of five parts. A fixed sleeve 21 is fixed to the end of the bracket 10, preventing it from moving relative to the bracket 10. A movable sleeve 22 is movably connected to the bracket 10, allowing it to move up and down along the bracket 10 to selectively approach or move away from the fixed sleeve 21. A tripod locking member 23 is screwed into the movable sleeve 22, and the tripod locking member 23 can increase the surface area of ​​the movable sleeve 22 in contact with the bracket 10 by rotating clockwise, thereby preventing the movable sleeve 22 from moving relative to the bracket 10. The tripod can move relative to the support 10 by rotating counterclockwise. Conversely, the tripod locking member 23 can reduce the surface area of ​​the movable sleeve 22 in contact with the support 10 by rotating counterclockwise, thereby allowing the movable sleeve 22 to move relative to the support 10. In addition, each tripod leg 24 is pivotally connected to the fixed sleeve 21. One end of each connecting rod 25 is pivotally connected to the movable sleeve 22, and the other end of each connecting rod 25 is pivotally connected to one of the tripod legs 24, so that each tripod leg 24 is provided with a connecting rod 25 between it and the fixed sleeve 21. In this embodiment, as shown in FIG3A As shown in Figure 3B, the movable sleeve 22 moves relative to the support 10 to move closer to the fixed sleeve 21, so that each leg 24 moves away from the support 10 to support the ground, thereby enabling the support leg 20 to present a supported state A1. As shown in Figure 3B, the movable sleeve 22 moves relative to the support 10 to move away from the fixed sleeve 21, so that each leg 24 swings toward the support 10, thereby enabling each leg 24 to be adjacent to the support 10, and thus enabling the support leg 20 to change from the supported state A1 to a retracted state A2.

[0025] As shown in Figure 2, the tilt adjuster 30 is connected between the bracket 10 and the connecting frame 40. The tilt adjuster 30 is used to change the tilt angle of the connecting frame 40. The tilt adjuster 30 has two parts: a longitudinal angle adjustment group 31 and a transverse angle adjustment group 32. As shown in the figure, the longitudinal angle adjustment group 31 has a longitudinal adjustment body 311 movably connected to the bracket 10 and a longitudinal locking member 312 screwed into the longitudinal adjustment body 311. The longitudinal adjustment body 311 can rotate relative to the bracket 10 about a longitudinal axis L1 parallel to the bracket 10. The longitudinal locking member 312 can increase the surface area of ​​the longitudinal adjustment body 311 in contact with the bracket 10 by rotating clockwise, thereby preventing the longitudinal adjustment body 311 from rotating about the longitudinal axis L1. Conversely, the longitudinal locking member 312 can decrease the surface area of ​​the longitudinal adjustment body 311 in contact with the bracket 10 by rotating counterclockwise, so that the longitudinal adjustment body 311 can rotate relative to the bracket 10. The longitudinal axis L1 is the axis of rotation. In addition, the lateral angle adjustment group 32 is provided with a lateral adjustment body 321 and a lateral locking member 322, as shown in the figure. A part of the lateral adjustment body 321 is connected to the longitudinal adjustment body 311 as a support part 321a, and the remaining part of the lateral adjustment body 321 is pivotally connected to the connecting frame 40 as a clamping part 321b, so that the connecting frame 40 can rotate relative to the lateral adjustment body 321 with a lateral axis L2 perpendicular to the longitudinal axis L1 as the axis. The lateral locking member 322 is screwed into the clamping part 321b. The lateral locking member 322 can increase the surface area of ​​the clamping part 321b in contact with the connecting frame 40 by rotating clockwise, thereby preventing the connecting frame 40 from rotating with the lateral axis L2 as the axis. Conversely, the lateral locking member 322 can reduce the surface area of ​​the clamping part 321b in contact with the connecting frame 40 by rotating counterclockwise, so that the connecting frame 40 can rotate with the lateral axis L2 as the axis.

[0026] Please refer to Figures 2, 4, and 5. The connecting frame 40 has two parts: a first connecting part 41 and a second connecting part 42. The first connecting part 41 is used to connect to the bracket arm assembly 50 and the limiting mechanism 60, while the second connecting part 42 is formed on the bottom side of the first connecting part 41 and is pivotally connected to the clamping part 321b of the lateral adjustment body 321. The lateral cross-sectional profile of the first connecting part 41 is larger than that of the second connecting part 42, so that the connecting frame 40 forms a surrounding area below the first connecting part 41. The exposed space 43 of the second connecting part 42 is located between the first connecting part 41 and the second connecting part 42, and the tilt adjuster 30 is located inside the exposed space 43, as shown in the figure. The connecting frame 40 is mainly composed of a connecting body 44 and a covering body 45. The connecting body 44 is provided with a recess 441, a connecting arm 442 and a pivot rod 443. The recess 441 is connected to the covering body 45, and a first bracket through hole 441a and a second bracket through hole 441b are formed around the recess 441. A switch through hole 441c is provided, and the first bracket through hole 441a, the second bracket through hole 441b, and the switch through hole 441c are all connected to a connecting space 441d recessed inside the recess 441. The connecting space 441d is connected to a positioning space 441e located below the connecting space 441d, so that the recess 441 can be sequentially recessed from top to bottom to form the connecting space 441d and the positioning space 441e. A first positioning surface 441f and a second positioning surface 441g are respectively formed on opposite sides of the positioning space 441e. The first positioning surface 441f is close to the switch through hole 441c, while the second positioning surface 441g is far from the switch through hole 441c. In addition, the connecting arm 442 is formed on the bottom side of the recess 441, and the pivot rod 443 can pass through the connecting arm 442 into the clamp 321b of the lateral adjustment body 321, so that the connecting arm 442 is adjacent to the tilt adjuster 30. In this embodiment, the recess 441 and the cover body 45 together form the first connecting part 41, and the connecting arm 442 and the pivot rod 443 together form the second connecting part 42.

[0027] Please refer to Figures 2, 4, and 5. The bracket arm assembly 50 is connected to the connecting frame 40. The bracket arm assembly 50 mainly consists of three bracket arms 51, which together form a clamping area R for securing the musical instrument. Each bracket arm 51 is provided with a support arm 511 and a claw sleeve 512 connected to the end of the support arm 511. In this embodiment, the support arm 511 of one bracket arm 51 is pivotally connected to the recess of the first connecting part 41. 441 is configured as a first swing bracket arm 51a, and the bearing arm 511 of the other bracket arm 51 is pivotally connected to another position of the recess 441 to form a second swing bracket arm 51b, so that the first and second swing bracket arms 51a and 51b can swing relative to the connecting frame 40. The bearing arm 511 of the last bracket arm 51 passes through the first and second bracket through holes 441a and 441b of the recess 441 to form a movable bracket arm 51c, so that the movable bracket... The arm 51c can move relative to the connecting frame 40 along a moving axis L3. When the movable bracket arm 51c passes through the first and second bracket through holes 441a and 441b, the supporting arm 511 of the movable bracket arm 51c can pass through the connecting space 441d of the connecting frame 40, such that the supporting arm 511 of the movable bracket arm 51c has an inner section 511a located inside the connecting space 441d and an outer section exposed through the first bracket through hole 441a in the connecting space. As shown in the figure, the first exposed section 511b outside the connecting space 441d and the second exposed section 511c exposed outside the connecting space 441d through the second bracket through hole 441b are respectively. The first exposed section 511b protrudes to form a first anti-detachment block 511d, and the end of the first exposed section 511b away from the connecting frame 40 can be fitted by the claw sleeve 512 of the movable bracket arm 51c, while the second exposed section 511c protrudes to form a second anti-detachment block 511e.

[0028] In this embodiment, as shown in FIG6A, the first and second swing bracket arms 51a and 51b of the bracket arm assembly 50 can swing relative to the connecting frame 40, so that the first and second swing bracket arms 51a and 51b are close to the first exposed section 511b of the movable bracket arm 51c, and then the first and second swing bracket arms 51a and 51b are respectively adjacent to the opposite sides of the first exposed section 511b, so that the bracket arm assembly 50 is in a closed state A3. As shown in FIG6B, the first and second swing brackets of the bracket arm assembly 50 Arms 51a and 51b can swing relative to the connecting frame 40, so that the first and second swing bracket arms 51a and 51b are away from the first exposed section 511b of the movable bracket arm 51c, and then the first and second swing bracket arms 51a and 51b are spaced on opposite sides of the second exposed section 511c of the movable bracket arm 51c. In this way, the bracket arm assembly 50 changes from the closed state A3 to the open state A4, so that the first and second swing bracket arms 51a and 51b together with the movable bracket arm 51c form the clamping area R.

[0029] Please refer to Figures 2, 4, and 5. The limiting mechanism 60 is disposed on the connecting frame 40. The limiting mechanism 60 has two parts within the connecting space 441d of the connecting frame 40: a movable member 61 and a returning member 62. As shown in the figures, the movable member 61 mainly consists of an actuating member 611, a brake pad 612, and a linkage member 613. The actuating member 611 is movably connected to the recess 441 of the connecting frame 40, and is located on one side of the concealed section 511a of the movable bracket arm 51c. The actuating member 611 can move relative to the connecting frame 40 along a braking axis L4 intersecting the moving axis L3, allowing the actuating member 611 to move through the switch through hole 441c in the connecting frame 40. Furthermore, the brake pad 612 is located on the other side of the concealed section 511a, such that the concealed section 511a is located between the actuating member 611 and the brake pad 612. The linkage 613 forms a first linkage part 613a connected to the actuating member 611 and a second linkage part connected to the brake pad 612. The first linkage 613a is located inside the positioning space 441e of the connecting frame 40 so as to span across the concealed section 511a, while the second linkage 613b is arranged vertically above the first linkage 613a. A receiving channel 63 for accommodating the concealed section 511a is formed between the actuating member 611, the brake pad 612, and the linkage 613. In this embodiment, because the two ends of the linkage 613 are respectively connected to the actuating member 611 and the brake pad 612, the linkage 613 is used to... The starting component 611 and the brake pad 612 move in the same direction along the brake axis L4. In addition, the return component 62 is a compression spring and is disposed between the wall surface of the recess 441 and the second linkage portion 613b of the linkage 613. When the two ends of the return component 62 contact the wall surface of the recess 441 and the second linkage portion 613b of the linkage 613 respectively, the return component 62 will deform to generate a limiting force F acting on the linkage 613 (as shown in Figure 7A).

[0030] Please refer to Figures 7A, 7B, 7C, and 7D for a specific application of the limiting mechanism 60 controlling the movement of the movable bracket arm 51c of the bracket arm assembly 50. First, as shown in Figure 7A, the return member 62 of the limiting mechanism 60, through the limiting force F, can simultaneously push the actuating member 611, brake pad 612, and linkage member 613 of the movable member 61. This causes the brake pad 612 to gradually approach the recessed section 511a of the movable bracket arm 51c, while the linkage member 613 moves towards the first positioning surface 441f of the positioning space 441e. Consequently, the actuating member 611 will gradually move away from the recessed section 511a, allowing the actuating member 611 to move inside the switch through hole 441c of the connecting frame 40. When the brake pad 612 contacts the movable bracket arm 51c... When the movable bracket arm 51c is in the concealed section 511a, the movable member 61 is in a contact position P1, causing friction between the brake pad 612 and the concealed section 511a. This prevents the movable bracket arm 51c from moving relative to the connecting frame 40, thus making it impossible to adjust the size of the clamping area R of the bracket arm assembly 50. In a preferred embodiment, when the movable member 61 is in the contact position P1, the linkage 613 is spaced at the first positioning surface 441f of the positioning space 441e. Additionally, as shown in FIG7B, the actuating member 611 is pressed, allowing the movable member 61 to move along the brake axis L4. The moving actuating member 611 can gradually approach the concealed section 511a, and the moving actuating member 611 can be driven by the linkage 613. The brake pad 612 moves, causing the movable member 61 to move from the contact position P1 to a separation position P2, allowing the brake pad 612 to separate from the recessed section 511a of the movable bracket arm 51c. Simultaneously, the linkage member 613 is spaced between the second positioning surface 441g of the positioning space 441e. This allows either the first positioning surface 441f or the second positioning surface 441g to limit the movement distance of the actuating member 611 within the connecting space 441d. When the movable member 61 is in the separation position P2, no frictional force is generated between the brake pad 612 and the recessed section 511a. At this time, as shown in Figure 7C, the movable bracket arm 51c moves relative to the connecting frame 40 along the moving axis L3, causing the first anti-disengagement block 511d of the movable bracket arm 51c to... The movable bracket arm 51c will move away from the connecting frame 40, while the second anti-detachment block 511e will move closer to the connecting frame 40. This causes the first exposed section 511b of the movable bracket arm 51c to increase in length, while the second exposed section 511c of the movable bracket arm 51c will shorten in length, thereby expanding the contour of the clamping area R. When the second anti-detachment block 511e contacts the recess 441 of the connecting frame 40, the movable bracket arm 51c will move relative to the connecting frame 40 while remaining stationary to prevent separation from the connecting frame 40, maximizing the contour of the clamping area R. Furthermore, as shown in Figure 7D, the movable bracket arm 51c moves relative to the connecting frame 40 along the moving axis L3, causing the first anti-detachment block 511d to move closer to the connecting frame 40.Simultaneously, the second anti-detachment block 511e will move away from the connecting frame 40, thereby shortening the length of the first exposed section 511b and the second exposed section 511c, thus reducing the profile of the clamping area R. When the first anti-detachment block 511d contacts the recess 441, the movable bracket arm 51c will move statically relative to the connecting frame 40 to prevent separation from the connecting frame 40, minimizing the profile of the clamping area R.

[0031] Please refer to Figure 8. In the second preferred embodiment, the difference from the first preferred embodiment lies in the arrangement between the movable bracket arm 51c of the bracket arm assembly 50 and the limiting mechanism 60. The structural configurations of the bracket 10, support leg 20, tilt adjuster 30, connecting frame 40, bracket arm assembly 50, and limiting mechanism 60 are the same as in the first preferred embodiment. Therefore, in this embodiment, the structural configurations of the bracket 10, support leg 20, tilt adjuster 30, connecting frame 40, bracket arm assembly 50, and limiting mechanism 60 will not be described again. As shown in the figure, the actuating element 611 and the brake pad 612 of the limiting mechanism 60 are both located on the same side of the recessed section 511a of the movable bracket arm 51c. The first linkage part 613a of the linkage 613 can be inserted through the column 46 formed in the connecting frame 40, so that the column 46 is located inside the receiving channel 63, and the return member 62 of the limiting mechanism 60 is located inside the receiving channel 63. The two ends of the return member 62 respectively contact the second linkage part 613b of the linkage 613 and the column 46 of the connecting frame 40. When the two ends of the return member 62 respectively contact the second linkage part 613b and the column 46 of the connecting frame 40, the return member 62 will deform to generate a limiting force F. In this way, the return member 62 can drive the brake pad 612 to the contact position P1 through the limiting force F, so that the movable bracket arm 51c cannot move relative to the connecting frame 40.

[0032] Please refer to Figure 9, which shows the specific application of adjusting the clamping area R in the second embodiment. The actuating member 611 of the limiting mechanism 60 is pulled and can move along the brake axis L4. The actuating member 611, brake pad 612 and linkage member 613 of the limiting mechanism 60 are all moved away from the inner section 511a of the movable bracket arm 51c, so that the movable member 61 moves from the contact position P1 to a separation position P2. In this way, the movable bracket arm 51c moves relative to the connecting frame 40 along the moving axis L3 to increase or decrease the size of the clamping area R.

[0033] Please refer to Figure 10. In the third preferred embodiment, the structural form of the linkage 613 of the limiting mechanism 60 differs from that of the first preferred embodiment. The structural forms of the bracket 10, support leg 20, tilt adjuster 30, connecting frame 40, and bracket arm assembly 50 are the same as in the first preferred embodiment. Therefore, in this embodiment, the structural forms of the bracket 10, support leg 20, tilt adjuster 30, connecting frame 40, and bracket arm assembly 50 will not be described again. As shown in the figure, the linkage 613 is used to allow the actuating member 611 of the limiting mechanism 60 to engage with the limiting mechanism 60. Both brake pads 611 and 612 can move in opposite directions along the brake axis L4, so that when the actuating member 611 can move along a first direction D1 of the brake axis L4, the brake pads 612 can simultaneously move along a second direction D2 of the brake axis L4, wherein the first direction D1 and the second direction D2 are opposite. In this embodiment, the linkage member 613 has three parts: a linkage gear 613c, an actuating rack 613d, and a contact rack 613e. The linkage gear 613c is pivotally connected to the recess 441 of the connecting frame 40, so that the linkage gear 613c can move relative to the recess 441. The seat 441 rotates, and the starting rack 613d is connected to the starting member 611. The starting rack 613d meshes with one side of the connecting gear 613c. Additionally, the contact rack 613e is connected to the brake pad 612, and the contact rack 613e meshes with the other opposite side of the connecting gear 613c, so that the contact rack 613e is arranged parallel to the starting rack 613d. The return member 62 of the limiting mechanism 60 is disposed between the connecting frame 40 and the contact rack 613e. When the return member 62 is disposed between the connecting frame 40 and the contact rack 613e, the limit mechanism 60... The return member 62 deforms to generate a limiting force F, which acts on the contact rack 613e. Through the limiting force F, the return member 62 can drive the contact rack 613e to move along the first direction D1 of the brake axis L4, so that the movable member 61 can move to the contact position P1, preventing the movable bracket arm 51c from moving relative to the connecting frame 40. At the same time, the contact rack 613e moving in the first direction D1 can drive the connecting gear 613c to rotate counterclockwise, so that the starting rack 613d can drive the starting member 611 to move along the second direction D2.

[0034] Please refer to Figure 11, which illustrates the specific application of adjusting the clamping area R in the third embodiment. The actuating member 611 of the limiting mechanism 60 is pulled and can move along the first direction D1 of the brake axis L4. The actuating rack 613d, which moves toward the first direction D1, can drive the connecting gear 613c of the connecting member 613 to rotate clockwise. At the same time, the clockwise rotating connecting gear 613c can drive the contact rack 613e of the connecting member 613 to move along the second direction D2 of the brake axis L4, so that the movable member 61 can move from the contact position P1 to the separation position P2 along the second direction D2. In this way, the movable bracket arm 51c moves relative to the connecting frame 40 along the moving axis L3 to increase or decrease the size of the clamping area R.

[0035] Please refer to Figure 12. In the fourth preferred embodiment, the difference from the third preferred embodiment lies in the structural form of the linkage 613 of the limiting mechanism 60. As shown in the figure, the linkage 613 has three parts: a linkage rod 613f, an actuating protrusion 613g, and a contact protrusion 613h. The linkage rod 613f is pivotally connected to the recess 441 of the connecting frame 40, so that the linkage rod 613f can rotate relative to the connecting frame 40. The linkage 613f has a starting slot 613f1 and a contact slot 613f2 formed at both ends, and a starting protrusion 613g is formed on the starting member 611 and inserts into the starting slot 613f1, while a contact protrusion 613h is formed on the brake pad 612 and inserts into the contact slot 613f2. The return member 62 of the limiting mechanism 60 is disposed between the connecting frame 40 and the linkage 613f. When the return member... When the return member 62 is positioned between the connecting frame 40 and the linkage 613f, the return member 62 will deform to generate a limiting force F, which acts on the linkage 613f. This allows the linkage 613f to rotate counterclockwise through the limiting force F. Consequently, the starting protrusion 613g will move inside the starting slot 613f1, while the contact protrusion 613h will simultaneously move inside the contact slot 613f2. This changes the relative positions between the starting protrusion 613g and the starting slot 613f1, and between the contact protrusion 613h and the contact slot 613f2. As a result, the brake pad 612 can move in the first direction D1 through the counterclockwise rotating linkage 613f, allowing the movable member 61 to be in the contact position P1. At the same time, the starting member 611 can move in the second direction D2 through the counterclockwise rotating linkage 613f.

[0036] Please refer to Figure 13, which illustrates the specific application of adjusting the clamping area R in the fourth embodiment. The actuating member 611 of the limiting mechanism 60 is pulled and can move along the first direction D1 of the brake axis L4, so that the actuating protrusion 613g of the linkage member 613 moves synchronously along the first direction D1, allowing the actuating protrusion 613g to move inside the actuating slot 613f1 of the linkage rod 613f. Consequently, the linkage rod 613f can rotate clockwise through the actuating member 611 moving along the first direction D1, thereby changing the relative position between the contact protrusion 613h of the linkage member 613 and the contact slot 613f2 of the linkage rod 613f. This causes the movable member 61 to move from the contact position P1 to the separation position P2 along the second direction D2. In this way, the movable bracket arm 51c moves relative to the connecting frame 40 along the moving axis L3 to increase or decrease the size of the clamping area R.

[0037] Please refer to Figure 14. In the fifth preferred embodiment, the difference from the first preferred embodiment lies in the structural form of the linkage 613 of the limiting mechanism 60. In this embodiment, the linkage 613 is used to convert linear motion into rotational motion. The linkage 613 connects the actuating member 611 of the limiting mechanism 60 and the brake pad 612 of the limiting mechanism 60, so that when the actuating member 611 moves along the brake axis L4, the linkage 613 can drive the brake pad 612 to swing. As shown in the figure, the linkage 613 has three parts: a rotating disk 613i, a moving rod 613j, and a swing rod 613k. The rotating disk 613i is pivotally connected to the connecting frame 40, and a disk body protrusion 613i1 is formed on the surface of the rotating disk 613i. The moving rod 613j is connected to the actuating member 611, and a part of the moving rod 613j that is close to the rotating disk 613i is provided that can be penetrated by the disk body protrusion 613i1. The longitudinal slot 613j1 is provided, and the swing rod 613k is connected between the brake pad 612 and the rotating disc 613i. The return member 62 of the limiting mechanism 60 is disposed between the connecting frame 40 and the swing rod 613k. When the return member 62 is disposed between the connecting frame 40 and the swing rod 613k, the return member 62 will deform to generate a limiting force F acting on the swing rod 613k. Thus, the return member 62, through the limiting force F, can drive the swing rod 613k to swing. The brake pad 612 contacts the movable bracket arm 51c, allowing the movable member 61 to move to the contact position P1, preventing the movable bracket arm 51c from moving relative to the connecting frame 40. At the same time, the rotating disc 613i rotates counterclockwise, causing the disc protrusion 613i1 to move inside the longitudinal slot 613j1, thereby changing the relative position between the disc protrusion 613i1 and the longitudinal slot 613j1, causing the moving rod 613j to drive the starting member 611 to move.

[0038] Please refer to Figure 15, which shows the specific application of adjusting the clamping area R in the fifth embodiment. The starting member 611 of the limiting mechanism 60 is pulled, which can drive the moving rod 613j of the linkage 613 to move along the brake axis L4. The moving rod 613j, which moves towards the first direction D1, can drive the rotating disk 613i of the linkage 613 to rotate clockwise. At the same time, the disk protrusion 613i1 of the rotating disk 613i moves inside the longitudinal slot 613j1 of the moving rod 613j. The swing rod 613k of the linkage 613 drives the brake pad 612 of the movable member 61 to separate from the movable bracket arm 51c, so that the movable member 61 is in the separated position P2. In this way, the movable bracket arm 51c moves relative to the connecting frame 40 along the moving axis L3 to increase or decrease the size of the clamping area R.
