[0024] As a technical optimization scheme of the utility model, the outer wall of first fixed link 1 and second fixed link 2 all are installed with internal thread block 4 through thread 14, and the one end of first fixed link 1 close to second fixed link 2 is installed in the inside of internal thread block 4 on second fixed link 2 through thread 14, and the one end of second fixed link 2 close to first fixed link 1 is installed in the inside of internal thread block 4 on first fixed link 1 through thread 14;Internal thread block 4 can be connected and fixed to first fixed link 1 and second fixed link 2 simultaneously through thread 14 when in use.

[0025] As a technical optimization scheme of the utility model, the connecting rod 3 away from the opposite end of the first fixed rod 1 and the second fixed rod 2 is rotatably installed with the connecting rod 3, the connecting rod 3 away from the first fixed rod 1 on the second fixed rod 2 is installed with the first connecting block 6, and the first connecting block 6 away from the second fixed rod 2 is provided with the fixed hole 7.

[0026] As a technical optimization scheme of the utility model, the connecting rod 3 away from the second fixed rod 2 on the first fixed rod 1 is installed with the fixed block 5, the side surface of the fixed block 5 is installed with the mounting seat 8, the mounting seat 8 away from the fixed block 5 is installed with the supporting rod 12, and the supporting rod 12 away from the fixed block 5 is installed with the second connecting block 9.

[0027] As a technical optimization scheme of the utility model, the outer wall of the first fixed rod 1 and the second fixed rod 2 is movably installed with the rubber protective sleeve 10, the outer wall of the rubber protective sleeve 10 is installed with the annular rubber elastic band 11 at both ends, and the two rubber elastic bands 11 are located on the outer wall of the two connecting rods 3.

[0028] As a technical optimization scheme of the utility model, the first fixed rod 1 and the second fixed rod 2 are provided with the connecting groove 15 away from the opposite end, the end of the two connecting rods 3 close to the first fixed rod 1 is installed with the rotating block 16, and the two rotating blocks 16 are rotatably installed in the two connecting grooves 15 respectively.

[0029] As a technical optimization scheme of the utility model, the two inner threaded blocks 4 are located in the rubber protective sleeve 10, and the second connecting block 9 away from the fixed block 5 is provided with a plurality of limiting grooves.

[0030] When the present invention is in use, a worker hinges the ends of the first fixing rod 1 and the second fixing rod 2 near their opposing surfaces so that the limiting plate 17 on the first fixing rod 1 is located between the inner wall of the fixing groove 13 of the second fixing rod 2 and the limiting plate 17 thereon, while the limiting plate 17 on the second fixing rod 2 is similarly located between the inner wall of the fixing groove 13 of the first fixing rod 1 and the limiting plate 17 thereon. When in use, the first fixing rod 1 and the second fixing rod 2 are connected to each other. When in use, a worker can stretch the first fixing rod 1 and the second fixing rod 2 to adjust the overall length of the first fixing rod 1 and the second fixing rod 2.

[0031] After the staff has adjusted the overall length of the first and second fixing rods 1, 2, they fine-tune the position of the threads 14 on the end of the first fixing rod 1 near the second fixing rod 2 and the threads 14 on the outer wall of the second fixing rod 2, so that the threads on the first and second fixing rods 1 and 2 are connected and correspond to each other. The staff rotates the internal thread blocks 4 on the first and second fixing rods 1 and 2, causing the internal thread block 4 on the second fixing rod 2 to move toward the first fixing rod 1, while the internal thread block 4 on the first fixing rod 1 moves toward the second fixing rod 2, until the end of the first fixing rod 1 near the second fixing rod 2 is located inside the internal thread block 4 on the second fixing rod 2, and the end of the second fixing rod 2 near the first fixing rod 1 is located inside the internal thread block 4 on the first fixing rod 1. In use, the same internal thread block 4 can simultaneously connect the first and second fixing rods 1 and 2 via the threads 14.

[0032] When in use, the first fixing rod 1 and the second fixing rod 2 are connected and limited to each other at one end near the opposite surface by two limiting plates 17. At the same time, the two internal thread blocks 4 are respectively connected and fixed to the first fixing rod 1 and the second fixing rod 2 by threads 14 on the first fixing rod 1 and the second fixing rod 2, which makes it convenient for the staff to adjust the overall length of the first fixing rod 1 and the second fixing rod 2 according to the usage conditions.

[0033] During use, the first and second fixing rods 1 and 2 are both located within the rubber protective sleeve 10, which protects the connection between the first and second fixing rods 1 and 2. The rubber expansion straps 11 at both ends of the rubber protective sleeve 10 use their elasticity to keep the ends of the rubber protective sleeve 10 in close contact with the surfaces of the first and second fixing rods 1 and 2, respectively, preventing external dust from settling on the first and second fixing rods 1 and 2. When the operator needs to adjust the overall length of the first and second fixing rods 1 and 2, the rubber protective sleeves 10 can be retracted, making it easier for the operator to adjust the overall length of the first and second fixing rods 1 and 2.

[0034] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
