[0039] Working principle: When in use, first place the connecting plate 3 on the upper part of the guide rail body 1, then rotate the stud 43 according to the size of the guide rail body 1 to drive the clamping plate 42 to move, then insert the upper part of the guide rail body 1 between the connecting plate 3 and the clamping plate 42, then rotate the stud 43 in the opposite direction to drive the clamping plate 42 close to the connecting plate 3, so that the device is fixed to the guide rail body 1, then according to the size of the guide block 2, rotate the limit rod 515 to loosen the adjustment plate 512, then pull the adjustment plate 512 to drive the fixing component 54 and the adjusting component 53 to adjust the position, when the position of the fixing component 54 is adapted to the position of the guide block 2, rotate the limit rod 515 in the opposite direction to make it close to the adjustment plate 512 and press it against the limit, then according to the distance between the clamping block 545 and the guide block 2, rotate the screw 533 to drive the slider 532 to move, thereby adjusting the position of the fixing component 54 connected to it at the lower part, when the position of the fixing component 54 is adjusted, rotate the adjusting rod 544 According to the direction of its rotation, it will drive the connecting block 543 to move. Since the auxiliary block 542 is connected to the housing 541, and the connecting block 543 is connected to the two auxiliary blocks 542, the connecting block 543 will be limited to a certain extent and will move horizontally. When it moves, the auxiliary block 542 connected to it through the protrusions and grooves will be driven to slide in the housing 541 and drive the clamping blocks 545 to move closer or farther from each other until the guide block 2 is clamped into the two clamping blocks 542. 45, so that the fixing component 54 and the guide block 2 are fixed. When the guide block 2 slides along the guide rail body 1, it will drive the clamping component 5 to move together through the fixing component 54, and the empty plate 511 and the ball 513 will slide in the sliding mouth 31. When it is necessary to fix the position of the guide block 2, the limit block 52 is rotated to move it downward along the fixing rod 514 and fit tightly with the connecting plate 3, so that the limit block 52 and the empty plate 511 clamp the connecting plate 3, and the position of the guide block 2 can be fixed.
