The inner part of the protective shell 401 is rotatably connected to a driven gear ring 404, and the outer part of the driven gear ring 404 is slidably connected to a clamping assembly for fixing. The driving wheel 403 is used to mesh with the driven gear ring 404 to transmit the rotational power of the motor 402 to the driven gear ring 404, driving the driven gear ring 404 to rotate inside the sliding protective shell 401. The clamping sliding strip 405 is used to slide in the outer groove of the sliding protective shell 401, and adjusts the clamping force and range of the ignition connection tube by its own position movement to ensure that the connection tube is firmly fixed.

[0027] Reference Figure 1 , Figure 2 and Figure 4The replacement mechanism 5 includes a detection suction block 501, which is externally fixedly connected to the outside of the support base 2. The detection suction block 501 slides externally, and a conduit inside the detection suction block 501 is used for air extraction. A replaceable fixing head 12 is slidably connected to the outside of the detection suction block 501. The replaceable fixing head 12 is used to mount the ignition connection pipe. A rotating column 506 is rotatably connected to the outside and inside of the replaceable fixing head 12. A limit ring 505 is externally fixedly connected to the rotating column 506. A pressure spring 504 is sleeved between the limit ring 505 and the replaceable fixing head 12. The rotating column 506 is externally fixedly connected to... There is a sliding column 502 and a rotating column 506 for driving the sliding column 502 connected to it to move synchronously, which facilitates operation. The limiting ring 505 is used to buffer and limit. The external fixed connection of the sliding column 502 is a limiting column 503. The pressure spring 504 is used to absorb the impact force during the installation process, so that the replaceable fixing head 12 can be smoothly positioned. The external rotatable connection of the sliding column 502 is inside the detection suction block 501. The external sliding connection of the limiting column 503 is inside the detection suction block 501. The limiting column 503 is used to slide inside the detection suction block 501, further limiting the movement range of the sliding column 502.

[0028] The detection component includes a support column 8, which is externally fixedly connected to the support base 2. A support plate 7 is fixedly connected to the top of the support column 8. The support column 8 supports the support plate 7 above. A cylinder 6 is fixedly connected to the top of the support plate 7. The cylinder 6 pushes the detection module 13. Two limit posts 503 are provided at the bottom of the support plate 7 to guide the detection module 13 to slide down. The drive end of the cylinder 6 is fixedly connected to the detection module 13. The detection module 13 is used to create a negative pressure environment to facilitate the display of results by the detection display body 10. The display component includes a detection display body 10, which is externally fixedly connected to the outside of the workbench 1. An air suction pipe 9 is fixedly connected to the output end of the air pump inside the detection display body 10. The other end of the air suction pipe 9 is fixedly connected to the outside of the detection suction block 501. The detection display body 10 is used to display various data transmitted by the detection module 13, so that the operator can understand the detection status in real time. The air suction pipe 9 is used to connect the detection display body 10 and the detection suction block 501.

[0029] Working principle: Turn on the device and press the switch 3 on the outside of the support base 2 to power on the device. Check whether the detection display body 10 in the display component is displaying normally to ensure that the overall operation of the device is good. According to the specifications and type of the ignition connection pipe to be tested, select the appropriate replaceable fixing head 12 and install it on the detection suction block 501. During installation, the rotating column 506 inside the replaceable fixing head 12 will drive the sliding column 502 to rotate, while the limiting column 503 slides inside the detection suction block 501. The pressure spring 504 and the limiting ring 505 play a buffering and limiting role to ensure that the replaceable fixing head 12 is installed firmly.

[0030] Place the ignition connection tube on the pad 11 to position it in a suitable detection position. Drive the drive wheel 403 to rotate via the drive end of the motor 402. The rotation of the drive wheel 403 will cause the driven gear ring 404 to rotate inside the sliding protective shell 401. When the driven gear ring 404 rotates, the clamping sliding strip 405 slides in the outer groove of the sliding protective shell 401, thereby achieving clamping and fixing of the ignition connection tube.

[0031] The cylinder 6 at the top of the support plate 7 pushes the detection module 13 downward, making it contact the ignition connection pipe. The air pump inside the detection display body 10 starts to work, and air is drawn from the detection air intake block 501 through the air intake pipe 9, so that a negative pressure environment is formed inside the ignition connection pipe. The detection module 13 starts to detect parameters such as pressure changes in the ignition connection pipe and transmits the detection data to the detection display body 10 for display and calculation.
