[0019] A method for using a fixed steel pipe bracket assembly for connecting automobile pipelines comprises the following steps:

[0020] S1: Preliminary fixing: two sections of automobile pipes to be connected are placed in the first pipe fixing mechanism and the second pipe fixing mechanism respectively. When placing, the pipes are placed in the first semicircular groove between the first sliding block and the second sliding block. The first threaded rod is rotated to rotate in the three first threaded holes, thereby pushing the first sliding block and the second sliding block to slide on the slider until the pipes are preliminarily clamped in the two first semicircular grooves. The preliminarily clamping of the two sections of automobile pipes is the same operation;

[0021] S2: Adjustment and fixation: After the automobile pipes at both ends are initially fixed, they are adjusted and fixed according to the diameter of the pipes and the distance between the two automobile pipes. When adjusting and fixing, the connection of the two automobile pipes is first fitted, and then the second threaded rod is rotated so that the second threaded rod rotates in the second threaded hole, so that one end of the second threaded rod gradually approaches the pipe until the pipe is completely locked and fixed, thereby connecting the two sections of the pipe;

[0022] S3: Multiple pipe clamping: In addition, two sections of automobile pipes are taken and placed in the two symmetrically arranged auxiliary pipe fixing mechanisms respectively. When placing, the automobile pipe is placed in the circular groove, and the third threaded rod is rotated so that the third threaded rod rotates in the third threaded hole, so that the lower end of the third threaded rod gradually approaches the automobile pipe until the automobile pipe is fixed in the circular groove. When the first sliding block and the second sliding block slide close to each other, the two auxiliary pipe fixing mechanisms will also gradually approach each other, so that the two pipes are fitted together, thereby connecting the other two sections of the pipe.

[0023] The present invention has at least the following beneficial effects:

[0024] 1. It can improve the fixing effect of automobile pipelines and effectively prevent shaking when the pipelines are fixed. It can fix multiple pipelines at the same time, thereby improving the efficiency of automobile pipelines during connection. At the same time, it can clamp and fix automobile pipelines with different apertures, thereby improving the practicality of the device. The device also has a moving effect, which is convenient for movement, thereby improving the flexibility of the device.

[0025] 2. When the device moves to the designated position, the main support rod arranged under the support base is rotated to make the fourth threaded rod and the fifth threaded rod simultaneously shrink toward the first internal threaded hole and the second internal threaded hole, thereby driving the second support plate to move toward the bottom of the support base until the bottom surface of the second support plate is in vertical contact with the ground, thereby fixing the device at the designated position and achieving the fixing effect of the device. The second rubber anti-slip pad improves the supporting effect of the second support plate and the anti-slip effect of the second support plate. The setting of the height of the second support plate being higher than the height of the moving mechanism effectively prevents the moving roller from still being in contact with the ground when the second support plate is lowered.

[0026] 3. By utilizing the setting of the traction device, it is convenient to pull the device to move. At the same time, the traction rod has a quick disassembly effect. After the device is moved to the designated position, it can be disassembled and placed to reduce the floor space. At the same time, the work of the staff will not be affected due to the excessive length of the traction rod. BRIEF DESCRIPTION OF THE DRAWINGS
