A double-headed screw rod 14 and a docking rod 32 are installed on the other side of the housing 1 through two connecting plates 13. Two sliding blocks 15 are installed on the double-headed screw rod 14 and the docking rod 32. The two sliding blocks 15 are respectively inserted into the two rollers 12 through two round rods 19 that penetrate the sliding blocks 15. A longitudinal plate 21 is sleeved on the two round rods 19. A spring 20 is sleeved on the round rod 19 between the sliding block 15 and the roller 12.

[0027] Both sides of the housing 1 are provided with movable holes 2, the motor 2 10 and the roller 12 are both located outside the housing 1, and the rotating rod 11 passes through the movable holes 2 on both sides of the housing 1 to connect the motor 2 10 and the roller 12. The motor 2 10 and the roller 12 are both exposed to the outside, so that the spacing between the rollers 12 can be clearly understood, and the operation is more convenient when adjusting the spacing between the rollers 12.

[0028] A U-shaped plate 22 is welded to the connecting plate 9, and a support plate 23 is welded to the U-shaped plate 22. One end of the support plate 23 passes through the movable hole 2 and extends to the inside of the housing 1. Two mounting plates 24 are welded to the bottom of the support plate 23 in the housing 1. The rotating rod 11 passes through the mounting plate 24 and is connected to the mounting plate 24 by a bearing. The connecting plate 9 is connected to the rotating rod 11 by a bearing through the mounting plate 24. The connecting plate 9, the U-shaped plate 22, the support plate 23, and the mounting plate 24 are welded into one body, and jointly carry the motor 2 10 and the rotating rod 11 to prevent the rotating rod 11 from losing support when the roller 12 is adjusted, causing the roller 12 to press and deform the rotating rod 11.

[0029] A circular block 17 is fixedly mounted on one side of the roller 12 away from the rotating rod 11 , and a circular slot 18 is provided on the circular block 17 .

[0030] The docking rod 32 is fixedly connected between the two connecting plates 13, the double-headed screw rod 14 is rotatably installed on the two connecting plates 13, a knob handle 25 is provided on the upper end of the double-headed screw rod 14, the sliding block 15 is slidably sleeved on the docking rod 32, a threaded block 26 is fixedly installed on the sliding block 15, a rectangular block 16 is fixedly installed on the threaded block 26, the threaded block 26 is threadedly installed on the double-headed screw rod 14, the sliding block 15 is installed on the double-headed screw rod 14 through the threaded block 26, the circular rod 19 penetrates the rectangular block 16 and then sleeves the spring 20 and is inserted into the circular slot 18 of the circular block 17, and the sliding block 15 is inserted into the roller 12 through the rectangular block 16, the circular rod 19, and the circular block 17.

[0031] The sliding block 15 is a linear optical axis guide rail slider with a locking device.

[0032] Two annular blocks 1 27 and one annular block 28 are fixedly sleeved on the circular rod 19. The two annular blocks 1 27 are located at one end of the circular rod 19 and outside the rectangular block 16. The annular block 28 is located at the other end of the circular rod 19 and the end of the circular rod 19 exceeds the annular block 28. The part of the circular rod 19 that exceeds the annular block 28 is inserted into the circular slot 18. The spring 20 is located between the annular block 28 and the rectangular block 16. A rubber pad 29 is provided between the annular block and the circular block 17.

[0033] The longitudinal plate 21 is provided with a sliding hole 30, which is in the shape of an elongated strip. The width of the sliding hole 30 is greater than the diameter of the circular rod 19 and less than the outer diameter of the annular block 28. Both circular rods 19 pass through the sliding hole 30 and the longitudinal plate 21 is located between the four annular blocks 28 of the two circular rods 19. The longitudinal plate 21 is sleeved on the two circular rods 19 through the sliding hole 30, and a pulling handle 31 is welded on one side of the longitudinal plate 21. The sliding hole 30 provides sufficient activity space for the two circular rods 19, so that when the two circular rods 19 are moved later, the connection between the two circular rods 19 and the longitudinal plate 21 will not be affected.

[0034] The working principle of the utility model is:

[0035] When the positions of the two rollers 12 need to be adjusted, the longitudinal plate 21 is first pulled by pulling the handle 31. The longitudinal plate 21 will drive the two circular rods 19 to slide on the two rectangular blocks 16 at the same time under the cooperation of the four annular blocks 1 27. The two springs 20 will gradually deform under the drive of the two annular blocks 28 and the extrusion generated by the two rectangular blocks 16. The left ends of the two circular rods 19 will gradually move out of the two circular slots 18 during the movement. At this time, there is no restriction of the two circular rods 19, and the two rollers 12 will be in an adjustable state. The locking device of the sliding block 15 is loosened, and then the knob handle 25 is turned to rotate the double-headed screw rod 14. Under the influence of the two sections of thread, the two threaded blocks 26 will move simultaneously on the double-headed screw rod 14. The two rectangular blocks 16 move the two circular rods 19 simultaneously under the drive of the two threaded blocks 26, so that the ends of the two circular rods 19 are staggered from the two circular slots 18 by a certain distance, and then the pulling handle 31 is released.

[0036] Then start the motor 5, the output shaft of the motor 5 will drive the double-headed screw 4 fixedly connected thereto, and the double-headed screw 4 will drive the corresponding synchronous wheel 6. Under the cooperation of the two synchronous wheels 6 and a synchronous belt 7, the two double-headed screws 4 will rotate at the same time. Under the influence of the two sections of threads on the two double-headed screws 4, the four moving blocks 8 will drive the two connecting plates 9 to move in pairs, and the two connecting plates 9 will drive the two rollers 12 to move through the cooperation of the two motors 2 10 and the two rotating rods 11, so as to complete the adjustment of the distance between the two rollers 12, and then turn off the motor 5.

[0037] After the position between the two rollers 12 is adjusted, the pulling handle 31 is pulled outward again, and the knob handle 25 is turned to rotate the double-headed screw rod 14. Under the influence of the two sections of the thread, the two threaded blocks 26 will move simultaneously on the double-headed screw rod 14, and the two rectangular blocks 16, driven by the two threaded blocks 26, move the two circular rods 19 simultaneously. After ensuring that the ends of the two circular rods 19 are aligned with the two circular grooves 18, slowly release the pulling of the pulling handle 31. Under the action of the elastic force of the two springs 20, the parts of the two circular rods 19 that exceed the annular block 28 will slowly be inserted into the two circular grooves 18. At this time, the locking device of the sliding block 15 is locked, so that the two rollers 12 are fixed again through the two circular rods 19.
