The sliding assembly 2 includes a rotating seat 201, a rotating groove 202, a rotating rod 203, a connecting plate 204, a sliding cylinder 205, an installation chamber 206, a positioning piece 207, a sliding spring 208, a sliding rod 209, a sliding roller 210, a limiting cylinder 211, a limiting bolt 212, and a side groove 213; A rotating seat 201 is welded to one end face of the measuring plate 1. There are two rotating seats 201, which are symmetrically welded to one end face of the measuring plate 1 to facilitate the adjustment of the angle of the connecting plate 204. A rotating groove 202 is opened on the inner side of the rotating seat 201. A rotating rod 203 is rotatably installed on the inner side of the rotating groove 202. A connecting plate 204 is connected to the outer side of the rotating rod 203. A sliding cylinder 205 is welded to one end of the connecting plate 204. An installation chamber 206 is provided on the inner side of the sliding cylinder 205. A positioning piece 207 is embedded in the inner side of the installation chamber 206. A sliding spring 208 is spot-welded to one end face of the positioning piece 207. A sliding rod 209 is slidably installed on the inner side of the installation chamber 206. The other end of the sliding spring 208 is spot-welded to the sliding rod 209. The outer diameter of the sliding rod 209 is equal to the inner diameter of the installation chamber 206, which facilitates quick support on the inner wall of the I-shaped channel steel. A sliding roller 210 is rotatably installed on one end face of the sliding rod 209. A movable groove is provided at the end of the sliding rod 209 and the corresponding position of the sliding roller 210. The sliding roller 210 is slidably connected to the sliding rod 209 through the movable groove, which facilitates quick sliding. A limiting cylinder 211 is welded at the top position of the outer side of the sliding cylinder 205. A limiting bolt 212 is threadedly connected to the inner side of the limiting cylinder 211. A side groove 213 is provided at the bottom end of the measuring plate 1.

[0016] A fixing component 3 is installed on the inner side of the connecting plate 204; The fixing component 3 includes a snap-fit ​​groove 301, a fixing threaded cylinder 302, a fixing mounting groove 303, a support bolt 304, a handle 305, and anti-slip rubber 306; The inner side of the connecting plate 204 is provided with a snap-fit ​​groove 301, and a fixed threaded cylinder 302 is embedded in the inner side of the snap-fit ​​groove 301. The inner side of the fixed threaded cylinder 302 is provided with a fixed mounting groove 303, and a support bolt 304 is threadedly connected to the inner side of the fixed mounting groove 303. The inner diameter of the snap-fit ​​groove 301 is equal to the outer diameter of the fixed threaded cylinder 302, and the outer diameter of the support bolt 304 is equal to the inner diameter of the fixed mounting groove 303, which is conducive to fixing the connecting plate 204.

[0017] The working principle and usage process of this utility model are as follows: First, the operator inserts the measuring plate 1 into the inside of the I-shaped channel steel and fixes the measuring plate 1 to the side of the I-shaped channel steel through the side slot 213. Then, the rotating rod 203 can be rotated in the rotating slot 202 inside the rotating seat 201, thereby adjusting the connecting plate 204 to rotate to the inside of the I-shaped channel steel. At this time, under the action of the sliding spring 208, the sliding rods 209 at both ends can be pushed outward at the same time. At this time, the sliding rollers 210 at both ends will be in contact with the inner wall of the I-shaped channel steel. Then the operator can tighten the limiting bolts 212 on the inner side of the limiting cylinder 211, so that the position of the sliding rod 209 can be pressed and fixed by the limiting bolts 212. Then the operator can push the connecting plate 204, so that the measuring plate 1 can be pushed inside the I-shaped channel steel. Then when the measuring plate 1 is pushed to one end of the arched channel steel and it is difficult to move, a cutting line is drawn along the measuring plate 1 inside the I-shaped channel steel, so that the excess part can be removed. A single person can operate conveniently and quickly, which can not only simplify the processing steps, but also further improve the manufacturing efficiency of the arched channel steel. Finally, when cutting channel steel of different specifications, the operator can rotate the connecting plate 204 to the designated position and then continuously rotate the handle 305 to drive the support bolt 304 to move in the fixed mounting groove 303 inside the fixed threaded cylinder 302. With continuous rotation, the anti-slip rubber 306 at the bottom of the support bolt 304 can be pressed against one side of the measuring plate 1, so that the measuring plate 1, the connecting plate 204 and the support bolt 304 can form a triangle, which can stably and quickly push the measuring plate 1, further improving the accuracy of measurement, and can be adapted to I-shaped channel steel of different specifications.

[0018] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
