[0014] The present utility model will be described in detail below in conjunction with the specific embodiments:

Four guide posts 3 are fixedly installed on the base 1 in a rectangular distribution. The top plate 2 is fixedly installed on the top of the guide posts 3. The cylinder body of the telescopic cylinder 21 is fixedly installed on the top plate 2. The push plate 4 is slidably installed on the guide posts 3. The piston rod of the telescopic cylinder 21 is fixedly connected to the push plate 4. Two support posts 5 are symmetrically and fixedly installed on the base 1. The positioning posts 51 are fixedly arranged on the tops of the support posts 5. Two sleeves 6 are fixedly installed on the bottom surface of the push plate 4. The sleeves 6 can be slidably sleeved on the positioning posts 51. A receiving groove 11 with an open front is provided on the base 1. The base 1 is fixedly installed on the workbench;
[0016] The darkroom mechanism consists of a darkroom bin 71, a first slider and a first linear slide rail 7. The first linear slide rail 7 is fixedly installed on the workbench. The first slider is fixedly installed at the bottom of the darkroom bin 71. The first slider is slidably installed on the first linear slide rail 7;
[0017] The light source mechanism consists of a light source bracket 82, a second slider 81 and a second linear slide 8. The second linear slide 8 is fixedly mounted on a workbench. The light source bracket 82 is fixedly mounted on the second slider 81. A spotlight light source is fixedly mounted on the light source bracket 82. The second slider 81 is slidably mounted on the second linear slide 8.
[0018] A reinforcing block 61 with an arc-shaped concave structure is also fixedly installed on the bottom surface of the push plate 4. The arc-shaped concave structure matches the structural shape of the lower pipe clamp 91 to avoid interference problems. The sleeve 6 is fixedly installed on the reinforcing block 61, which can increase the installation structural strength of the sleeve 6 and avoid bending and deformation due to excessive pressure.
[0019] The top of the positioning column 51 is configured as a frustum-shaped structure. When the sleeve 6 is slidably sleeved on the positioning column 51, the frustum-shaped structure on the top can play a guiding role.
[0020] A guide sleeve 41 is fixedly mounted on the push plate 4, and the guide sleeve 41 is slidably mounted on the guide column 3. The through hole precision of the guide sleeve 41 is easier to process, and the guiding effect of the guide sleeve 41 can improve the straightness of the push plate 4 when it moves up and down.
[0021] The connection hole of the upper pipe hoop 92 with the connecting rod 101 is sleeved on the positioning column 51, and the upper pipe hoop 92 is placed on the supporting column 5, the connecting rod 101 is placed in the accommodating groove 11, the annular structure of the gasket 52 is sleeved and installed on the positioning column 51, and the gasket 52 is also placed on the upper pipe hoop 92, the simulated pipeline 10 (the outer diameter of the simulated pipeline 10 is the same as the outer diameter of the actual pipeline) is placed on the upper pipe hoop 92, the connection hole of the lower pipe hoop 91 is sleeved on the positioning column 51, and the lower pipe hoop 91 is also placed on the gasket 52, the piston rod of the telescopic cylinder 21 is started to telescope and push the push plate 4 to move downward along the guide column 3, The sleeve 6 is slidably sleeved on the positioning column 51, and the sleeve 6 presses the lower pipe hoop 91 to position it on the cushion sleeve 52. The lower pipe hoop 91 and the upper pipe hoop 92 press and fix the simulated pipe 10, and push the darkroom bin 71 and the spotlight source to align with the simulated pipe 10 along the first linear slide 7 and the second linear slide 8 respectively. The spotlight source is turned on, and the light-transmitting contour on the black curtain of the darkroom bin 71. The simulated pipe 10 is set to a solid structure or an outer end blocking structure to avoid brightness interference caused by passing through the simulated pipe 10 to the light-transmitting contour in the gap between the simulated pipe 10, the upper pipe hoop 92 and the lower pipe hoop 91. The tester pulls the simulated pipe 10. If the simulated pipe 10 can slide between the upper pipe hoop 92 and the lower pipe hoop 91, the upper pipe hoop 92 and the lower pipe hoop 91 are unqualified products. If the simulated pipe 10 cannot be pulled, observe the light-transmitting contours at the gaps between the upper pipe hoop 92 and the lower pipe hoop 91 and the simulated pipe 10, and then make a good / bad product qualification judgment based on the area of the light-transmitting contours on the black curtain of the darkroom 71.
