The support arms 12 are arranged at both ends of the profile support 13, and rotating feet 14 are respectively arranged at both ends of the support arms 12; the detection mechanism 2 includes a support plate 21 and measuring parts 22 arranged at both ends of the support plate 21; the measuring part 22 includes a rotating motor 221, a sensor 222 and an L-shaped bracket 223. The L-shaped bracket 223 is fixedly connected to the end of the support plate 21, the sensor 222 is rotatably connected to the L-shaped bracket 223, and the rotating motor 221 is fixed on the L-shaped bracket 223 for driving the rotation of the sensor 222; the support plate 21 is arranged on the slide rail 11 and slides along the slide rail 11.

[0041] The sensor 222 can be a 1D laser displacement sensor.

[0042] It should be noted that the rotating feet 14 are arranged to be foldable relative to the support arms 12. The folding mechanism is prior art and will not be elaborated; the lower part of the rotating feet 14 is designed to be rotatable, and the realization of its rotation is prior art and will not be elaborated.

[0043] The lower part of the rotating feet 14 is a U-shaped mechanism. When the rotating feet 14 are placed on the carbon skateboard and rotated to closely adhere to the carbon skateboard, it has a certain stabilizing effect.

[0044] The sliding rail 11 is arranged on the profile bracket 13. A sliding plate 111 is slidably arranged on the sliding rail 11. The sliding plate 111 slides along the sliding rail 11 on the sliding rail. The sliding plate 111 and the sliding rail 11 are commercially available products, and their specific connection structure is the prior art and will not be elaborated.

[0045] A stepping motor 23 is arranged on one side of the support plate 21, and a rack 15 adapted to the stepping motor 23 is arranged on the side of the profile bracket 13; it travels along the rack 15 driven by the stepping motor 23, thereby driving the movement of the support plate 21.

[0046] By placing the rotating feet 14 of the support frame 1 on the carbon sliding plate to be detected, the detection mechanism 2 slides along the sliding rail 11 of the support frame 1, thereby driving the sensor 222 of the measuring part 22 to detect the carbon sliding plate; during the sliding process, the rotating motor 221 drives the sensor 222 to rotate reciprocally to detect more of the plate surface of the carbon sliding plate, which can realize more comprehensive measurement of the carbon sliding plate to improve the measurement accuracy, and its operation is convenient, thereby improving the maintenance efficiency.

[0047] In another embodiment, refer to Figures 5-7 As shown, the support arm 12 includes a first support arm 121, a second support arm 122, and a third support arm 123.

[0048] The profile bracket 13 is of a three-section structure, and adjacent two sections of the profile bracket 13 are connected by a hinge 131. The corresponding sliding rail 11 and rack 15 are both arranged in a three-section structure, and each section is independently and fixedly arranged on the corresponding single-section profile bracket 13.

[0049] By folding the support arm 12 and the profile bracket 13, the volume is reduced, so as to be convenient to carry with a smaller storage box.

[0050] A positioning bolt 132 is arranged on one side of the hinge 131, and a positioning hole 133 is arranged on the corresponding side. When the profile bracket 13 is unfolded, the positioning bolt 132 is inserted into the positioning hole 133 to align the connection parts of the three-section structure of the sliding rail 11 and the rack 15, and make up for the misalignment of the connection parts of the sliding rail 11 and the rack 15 caused by the gap at the rotating shaft of the hinge 131. At the same time, the insertion of the positioning bolt 132 into the positioning hole 133 also plays a role in fixing the profile bracket 13 after it is unfolded.

[0051] In another embodiment, refer to Figures 8-9As shown, the support plate 21 is arranged on the sliding plate 111 through a quick-release device 3; the quick-release device 3 includes a connecting body 31 arranged on the bottom side of the support plate 21 and a clamping mechanism 32 arranged on the sliding plate 111.
