[0040] like Figures 1 to 4 As shown, a multifunctional support device 100 includes a first support component 1, a second support component 2, a first adjustment mechanism 4, and a second adjustment mechanism 5. The first end of the first support component 1 has a movable groove 111 for accommodating the first adjustment mechanism 4. In a first direction, the first adjustment mechanism 4 slides with the inner wall of the first support component 1; the second end of the first support component 1 is sleeved on the outside of the second support component 2, and in a second direction, the second support component 2 slides with the first support component 1; the second adjustment mechanism 5 is sleeved on the outside of the second support component 2 and threadedly engaged with the outer wall of the first support component 1, and the second adjustment mechanism 5 is at least partially used to resist the second support component 2; wherein the first direction intersects with the second direction.

[0041] In this embodiment, the second support assembly 2 is used to fix or clamp the workpiece, and the inner wall of the first support assembly 1 is used to slide with the first adjustment mechanism 4 in the first direction. The first adjustment mechanism 4 is used to be installed on the base, so the workpiece is moved in the first direction by the first adjustment mechanism 4. The first support assembly 1 is sleeved on the outside of the second support assembly 2, and slides with the second support assembly 2 in the second direction to adjust the position of the second support assembly 2 in the second direction. After the second support assembly 2 moves to the preset position, the second adjustment mechanism 5 fixes the second support assembly 2 to improve the stability of the second support assembly 2 when supporting the workpiece. Moreover, the first direction intersects with the second direction. Therefore, this multifunctional support device 100 is used to adjust the position of the workpiece in two different directions. The first direction is the horizontal movement direction of the workpiece, and the second direction is the height movement direction of the workpiece, which improves the problem that the existing clamping device cannot adjust the height and horizontal position of the workpiece.

[0042] like Figures 1 to 4 As shown, the support device 100 further has a guide block 113, the first support component 1 has a mounting groove and a through-hole 114, the mounting groove is provided on the inner wall of the movable groove 111, the through-hole 114 runs through from one side of the first support component 1 to the other side and communicates with the mounting groove, the guide block 113 is installed in the mounting groove through the through-hole 114, and the outer wall of the first adjustment mechanism 4 has a guide groove matched with the guide block 113. In this embodiment, the guide block 113 is installed in the mounting groove through the through-hole 114, a part of the guide block 113 is located in the mounting groove, and another part of the guide block 113 is located in the guide groove, so that in the first direction, the outer wall of the first adjustment mechanism 4 and the inner wall of the first support component 1 are slidably matched; moreover, by providing the through-hole 114, the guide block 113 is conveniently installed, and the structural compactness between the first adjustment mechanism 4 and the first support component 1 is improved.

[0043] like Figure 3 and Figure 4As shown, the first adjustment mechanism 4 includes a clamping assembly 32 and a first support column 41, the first support column 41 is at least partially installed in the clamping assembly 32, and the clamping assembly 32 is slidably matched with the inner wall of the first support assembly 1 in the movable groove 111; the first support assembly 1 has a first adjustment hole 112 extending along the first direction, and the first adjustment hole 112 corresponds to the second adjustment hole 321 of the clamping assembly 32. In this embodiment, the clamping assembly 32 is used to install and remove the first support column 41, and the first support column 41 is used to be fixed on the base. When the first support column 41 is fixed to the base, the position of the workpiece on the second support assembly 2 can be adjusted by moving the first support assembly 1. Moreover, on the adjustment clamping assembly 32, the first support assembly 1 has a first adjustment hole 112 extending along the first direction, and the first adjustment hole 112 corresponds to the second adjustment hole 321 of the clamping assembly 32. A tool is used to pass through the first adjustment hole 112 and insert into the second adjustment hole 321 to adjust the clamping assembly 32; at the same time, the clamping assembly 32 is also hidden in the first support assembly 1.

[0044] like Figure 3 and Figure 5 As shown, the second adjustment mechanism 5 has a rotating block 51, the first end of which is sleeved on the outside of the first support assembly 1 and threadedly matched with the first support assembly 1; in the second direction, at least part of the rotating block 51 is against the second support assembly 2; in the third direction, the second end of the rotating block 51 is slidably matched with the second support assembly 2. The inner wall of the rotating block 51 has an internal thread, and the outer wall of the first support assembly 1 has an external thread 121. The rotating block 51 is driven to rotate so that the internal thread and the external thread 121 are matched, so that the rotating block 51 drives the second support assembly 2 to move up and down in the second direction to achieve the height adjustment of the second support assembly 2; and the rotating block 51 is slidably matched with the second support assembly 2 in the third direction, reducing the friction between the rotating block 51 and the second support assembly 2, and reducing the force required to drive the rotating block 51. In this embodiment, the third direction is the rotation direction of the rotating block 51.

[0045] like Figure 3 and Figure 5As shown, the second adjustment mechanism 5 also has a moving block 52, a first bearing 53, a second bearing 54, a support block 55, and a fastener 56. The moving block 52 is installed on the side wall of the rotating block 51. The first bearing 53 and the second bearing 54 are both sleeved on the outside of the second supporting component 2. The moving block 52 is located between the first bearing 53 and the second bearing 54. The moving block 52 is abutted against the second supporting component 2 through the first bearing 53, and the rotating block 51 is rollingly matched with the second supporting component 2 through the first bearing 53 and the second bearing 54; the support block 55 is installed on the second supporting component 2 and is located at the lower end of the second bearing 54. In this embodiment, the rotating block 51 is in rolling cooperation with the second support assembly 2 through the first bearing 53 and the second bearing 54, thereby reducing the friction between the rotating block 51 and the second support assembly 2 and further reducing the force required to drive the rotating block 51; moreover, the second bearing 54 is supported by a support block 55, and the support block 55 is fixed to the second support assembly 2 by a fastener 56. When the second support assembly 2 moves, the first bearing 53 and the second bearing 54 are driven to move by the support block 55, so that the rotating block 51 is always in rolling cooperation with the first bearing 53 or the second bearing 54.

[0046] like Figure 3 , Figure 4 and Figure 6 As shown, the first adjustment mechanism 4 also has a first locking assembly 6, which is movably installed in the first support assembly 1, and the first locking assembly 6 has a first moving position and a second moving position. In the first moving position, at least part of the first locking assembly 6 abuts against the second support assembly 2; in the second moving position, the first locking assembly 6 is away from the second support assembly 2. In this embodiment, when the first adjustment mechanism 4 drives the second support assembly 2 to move to the preset position, the first locking assembly 6 is then moved to the first moving position in the first support assembly 1, abuts against the second support assembly 2, and fixes the second support assembly 2, thereby improving the stability of the second support assembly 2 when supporting the workpiece. When it is necessary to adjust the position of the second support assembly 2 in the second direction again, the first locking assembly 6 moves to the second moving position, and the first locking assembly 6 is away from the second support assembly 2, thereby realizing the movable adjustment of the second support assembly 2 in the second direction.

[0047] like Figure 3 and Figure 6As shown, the first locking assembly 6 includes a first clamping block 61, a transmission block 63, and a driving block 64. The first clamping block 61 is installed in the first supporting assembly 1 and slidably cooperates with the inner wall of the first supporting assembly 1; the transmission block 63 is installed in the first clamping block 61 and is used to abut against the first clamping block 61. The transmission block 63 is sleeved on the first end of the driving block 64 and threadedly cooperates with the first end of the driving block 64. The driving block 64 is rotatably installed in the first supporting assembly 1, and the second end of the driving block 64 is used to abut against the first supporting assembly 1; in the rotation direction of the driving block 64, the transmission block 63 abuts against the inner wall of the first clamping block 61. In this embodiment, by driving the driving block 64 to rotate, due to the threaded fit between the driving block 64 and the transmission block 63, and in the transmission direction of the driving block 64, the transmission block 63 abuts against the first clamping block 61, therefore, the transmission block 63 cannot rotate with the driving block 64, so that a friction force is generated between the driving block 64 and the transmission block 63, and this friction force drives the transmission block 63 to move, and pushes the first clamping block 61 to move in the first support assembly 1 toward the second support assembly 2, thereby abutting against the outer wall of the second support assembly 2 to fix the position of the second support assembly 2.

[0048] like Figure 6 As shown, the first locking assembly 6 also includes a second clamping block 62, which is sleeved on the second end of the driving block 64. The second end of the driving block 64 is used to abut against the inner wall of the second clamping block 62. When the driving block 64 rotates clockwise or counterclockwise, it will simultaneously drive the first clamping block 61 and the second clamping block 62 to move closer to or away from each other, thereby fixing the second support assembly 2. The first clamping block 61 and the second clamping block 62 are staggered in the circumferential direction of the second support assembly 2, so that the first clamping block 61 and the second clamping block 62 abut against the outer wall of the second support assembly 2 at different positions in the circumferential direction of the second support assembly 2, further improving the stability of the second support assembly 2 after being fixed.

[0049] In this embodiment, the driving block 64 includes a driving portion 641 and an abutting portion 642 . The driving portion 641 and the abutting portion 642 are an integrated structure. The driving portion 641 is used to drive the transmission block 63 to move, and the abutting portion 642 is used to abut against the second clamping block 62 .

[0050] like Figure 3 and Figure 4As shown, the support device 100 also has a third support assembly 3, the first support assembly 1 includes a first support portion 11 and a first overlap portion 12, the second support assembly 2 includes a second support portion 22 and a spherical boss 21; the first overlap portion 12 is mounted on the first support portion 11, and the first overlap portion 12 is sleeved on the bottom of the second support portion 22 and slidably cooperates with the second support portion 22; the spherical boss 21 is mounted on the top of the second support portion 22, the third support assembly 3 has a groove 33, the spherical boss 21 is at least partially located in the groove 33, and the inner wall of the third support assembly 3 is rotatably cooperated with the spherical boss 21. In this embodiment, the first overlap portion 12 is used to be sleeved on the bottom of the second support portion 22, and the second support portion 22 is slidably cooperated with the first overlap portion 12, so as to further realize the movement and adjustment of the second support assembly 2 in the second direction. Moreover, the second support portion 22 is installed with a spherical boss 21, which is used to cooperate with the groove 33, so that the third support assembly 3 and the second support portion 22 can be rotatably matched to achieve angle adjustment of the workpiece on the third support assembly 3, further improving the flexibility of the workpiece on the support device 100.

[0051] like Figure 3 and Figure 4 As shown, the third support assembly 3 includes a third support portion 35, a stopper 34, and a second locking assembly 7. The second locking assembly 7 is movably installed in the second support portion 22. The first end of the stopper 34 passes through the third support portion 35 and the spherical boss 21 in sequence. The second locking assembly 7 is used to abut against the first end of the stopper 34, and the second end of the stopper 34 is used to abut against the third support portion 35. In this embodiment, when the second locking assembly 7 abuts and fixes the first end of the stopper 34, the second end of the stopper 34 abuts against the third support portion 35, thereby limiting the rotation of the third support portion 35; when the third support portion 35 is rotated and adjusted to a preset position, the second locking assembly 7 is used to fix the stopper 34, thereby limiting the rotation of the third support portion 35 and improving the stability of the third support portion 35 on the supported workpiece. Moreover, the second locking assembly 7 adopts the same structure as the first locking assembly 6, and no additional design is required.

[0052] In this embodiment, the third support assembly 3 further comprises a second support column 31 and a clamping assembly 32 . The second support column 31 is used to fix the workpiece. The clamping assembly 32 is installed in the third support portion 35 and is used to disassemble or install the second support column 31 .
