[0021] In this embodiment, first, according to the spacing between the front forks of the front fork body 7, the transmission mechanism is started to drive the two sliders 11 to move, so as to adapt to the front fork bodies 7 with different spacings, thereby reducing the limitations of the device, and then one side of the front fork body 7 is placed in the limiting mechanism inside the fixing frame 4, and then one side of the front fork body 7 is fixed by rotating the limiting mechanism to avoid the problem of its separation, thereby increasing the stability of the device, and then according to the length of the front fork body 7, the displacement plate 9 is driven to move by starting the displacement mechanism and at the same time drive the inner wall of the placement block 18 to contact one end of the front fork body 7, thereby completing the fixation of the front fork body 7, so that different models of front fork bodies 7 can be fixed, thereby increasing the practicality of the device, and finally the outer side of the front fork body 7 is detected by starting the ultrasonic detector 6.

[0022] Among them, the transmission mechanism includes two second fixed blocks 17, the two second fixed blocks 17 are fixedly connected to the top of the base plate 1, and a bidirectional screw rod 16 is rotatably connected between the two second fixed blocks 17. A first motor 10 is fixedly installed on one side of one of the second fixed blocks 17, one end of the output shaft of the first motor 10 is fixedly connected to one end of the bidirectional screw rod 16, and the outer side of the bidirectional screw rod 16 is connected to the internal thread of the slider 11.

[0023] The transmission mechanism further includes a slide bar 24, which is fixedly connected between the two first fixed blocks 2, and one side of the slider 11 is slidably connected to the outer side of the slide bar 24. When adjusting the spacing between the two sliders 11, the output shaft of the first motor 10 is started to drive the bidirectional screw rod 16 to simultaneously drive the two sliders 11 to move, and then one side of the two sliders 11 slides on the outer side of the slide bar 24 when the two sliders 11 move, and the slider 11 is limited by the slide bar 24, so that it moves more smoothly and will not be separated, and then the limit mechanism is driven to move when the slider 11 moves, so as to adapt to the front fork body 7 with different spacings, thereby increasing the practicality of the device.

[0024] The limiting mechanism includes a threaded rod 14 which is threadedly connected to the top of the fixing frame 4 , and a contact plate 15 which is rotatably connected to the bottom of the threaded rod 14 , and one side of the contact plate 15 contacts the outer side of the front fork body 7 .

[0025] The limiting mechanism further includes a limiting groove 13, which is provided on both sides of the fixing frame 4. The limiting groove 13 is slidably connected to the limiting rod 12 inside, and one end of the limiting rod 12 is fixedly connected to one side of the abutment plate 15. When the front fork body 7 is limited and fixed, the abutment plate 15 is driven to move toward the outside of the front fork body 7 to abut against it by rotating the threaded rod 14. The movement of the abutment plate 15 simultaneously drives the limiting rod 12 to slide inside the limiting groove 13, and then guides the movement of the abutment plate 15, so that it can better abut and fix the front fork body 7, thereby increasing the stability of the device.

[0026] Among them, the displacement mechanism includes two vertical plates 21, the two vertical plates 21 are fixedly connected to the top of the base plate 1, and a reciprocating screw 22 is rotatably connected between the two vertical plates 21. A second motor 23 is fixedly installed on one side of one of the vertical plates 21, and one end of the output shaft of the second motor 23 is fixedly connected to one end of the reciprocating screw 22. The outer side of the reciprocating screw 22 is threadedly connected to a displacement plate 9, and one side of the displacement plate 9 is fixedly connected to a placement block 18, and the inner wall of the placement block 18 is in contact with the outer side of the front fork body 7.

[0027] The displacement mechanism further includes a displacement groove 20, which is provided on one side of the transverse plate 8. A displacement rod 19 is slidably connected inside the displacement groove 20, and one end of the displacement rod 19 is fixedly connected to one side of the displacement plate 9. When fixing the front fork bodies 7 of different lengths, the reciprocating screw 22 is driven to rotate by the output shaft of the second motor 23, and the displacement plate 9 is driven to approach one side of the front fork body 7. Then, when the displacement plate 9 moves, the displacement rod 19 is driven to slide inside the displacement groove 20, thereby limiting the moving direction of the displacement plate 9 to avoid the problem of offset when it moves. Then, after the displacement plate 9 approaches one side of the front fork body 7, one end of the front fork body 7 is fitted with the inner wall of the placement block 18, thereby further fixing and limiting the front fork body 7, thereby further increasing the practicality of the device.

[0028] Working principle: First, when adjusting the spacing between the two sliders 11, the output shaft of the first motor 10 is started to drive the bidirectional screw rod 16 to move the two sliders 11 at the same time, and then one side of the two sliders 11 slides on the outside of the slide rod 24 when moving, and the slider 11 is limited by the slide rod 24, so that it moves more smoothly and will not fall off. Then, when the slider 11 moves, the limiting mechanism is driven to move, so as to adapt to the front fork body 7 with different spacings, thereby increasing the practicality of the device. Next, when the front fork body 7 is limited and fixed, the threaded rod 14 is rotated to drive the contact plate 15 to move to the outside of the front fork body 7 to contact it. The movement of the contact plate 15 simultaneously drives the limiting rod 12 in the limiting groove 13 The fork body 7 is fixed to the rear end of the fork body 7 by the reciprocating screw 22 and the displacement plate 9 is driven to move closer to one side of the fork body 7 by the output shaft of the second motor 23. Then, when the displacement plate 9 moves, the displacement rod 19 is driven to slide inside the displacement groove 20, thereby limiting the moving direction of the displacement plate 9 and avoiding the problem of offset when the displacement plate 9 moves. After the displacement plate 9 is close to one side of the fork body 7, one end of the fork body 7 is fitted with the inner wall of the placement block 18, thereby further fixing and limiting the front fork body 7, thereby further increasing the practicality of the device.
