The limiting plate 424 is fixedly connected to one end of the two moving rods 421 extending out of the box body 41.

[0025] Adopting the above scheme: By setting the clamping component 42, it is used to clamp and fix the connecting head 5 fixed on the lower surface of the measuring head 3, which has the function of clamping and fixing the measuring head 3 through the connecting head 5.

[0026] Referring to Figure 2 and Figure 3, the control component 43 includes a rotating rod 431, a rotating member 432, a first fixed shaft 433, a second fixed shaft 434, and a push rod 435. The rotating rod 431 is arranged below between the two snap rings 422. The lower end of the rotating rod 431 penetrates through the base 1 and is rotatably connected to the base 1. The rotating member 432 is sleeved on the upper surface of the upper end of the rotating rod 431 and is fixedly connected to the rotating rod 431.

[0029] Adopting the above solution: By setting the connecting head 5 on the lower surface of the measuring head 3, it is used to cooperate and clamp with the two clamping components 42, so as to fix the measuring head 3.

[0030] Reference Figure 2 And Figure 3 , limiting blocks 6 are respectively arranged on the left and right sides inside the box body 41.

[0034] Working principle of the present utility model: When installing and fixing the measuring head 3, the connector 5 at the lower end of the measuring head 3 is aligned and inserted into the box body 41. While inserting into the box body 41, the connector 5 squeezes and moves the two snap rings 422 to both sides. While the two snap rings 422 move to the left and right sides, they drive the moving rod 421 to move in the box body 41, and at the same time compress the spring 423. After the connector 5 is completely inserted into the box body 41, the spring 423 will rebound, push the two snap rings 422 together, thereby clamping the connector 5 to complete the fixation of the measuring head 3. When disassembling the measuring head 3, by rotating the knob 7, while the knob 7 rotates, it drives the rotating rod 431 to rotate. While the rotating rod 431 rotates, it drives the rotating part 432 to rotate. While the rotating part 432 rotates, it pushes the push rod 435 through the fixed shaft one 433. While the push rod 435 moves, it pushes the fixed shaft two 434 to push the two snap rings 422 to both sides, thereby releasing the fixation of the connector 5, and then lifting the measuring head 3 upward to complete the disassembly.

[0035] In summary, for this steel structure anti-deformation detection device, by setting the base 1, support rod 2, measuring head 3, fixing device 4, box body 41, clamping assembly 42, moving rod 421, snap ring 422, spring 423, limiting plate 424, control assembly 43, rotating rod 431, rotating part 432, fixed shaft one 433, fixed shaft two 434, push rod 435, connector 5, limiting block 6 and knob 7 to cooperate with each other, it solves the problem that the measuring head of the existing level is usually installed and fixed by bolts, which is rather troublesome during installation and disassembly, thus resulting in inconvenient disassembly and assembly and affecting work efficiency.
