[0033] Reference Figure 2 , Figure 3 and Figure 4 The right end of the extrusion block 38 is fixedly connected with a positioning rod 37 for fixing the sliding sleeve 31. The positioning rod 37 passes through and is slidably connected to the right end of the storage box 35. The left end of the connector 1 is provided with a positioning groove 34 near the front end for accommodating the positioning rod 37. When the sliding sleeve 31 is aligned with the connector 1, the positioning rod 37 will be aligned with the positioning groove 34. The positioning groove 34 and the positioning rod 37 are adapted.

[0034] Working principle: When it is necessary to adjust and use different types of suction devices 2, the suction device 2 can be pulled to the left first. The suction device 2 will drive the extrusion block 38 to move to the left synchronously. First, the right end of the suction device 2 will disengage from the inside of the connector 5. Subsequently, the extrusion block 38 will drive the positioning rod 37 to disengage from the inside of the positioning groove 34. Then, the sliding sleeve 31 can be rotated so that its outer wall fits against the outer wall of the top end of the connector 1. At this time, the suction device 2 can be released. The adjusting spring 36 will drive the suction device 2 to be stuck inside the sliding sleeve 31 by pulling the extrusion block 38. At the same time, the torsion spring 33 will pull the sliding sleeve 31 so that it will not rotate downward randomly. Then, another group of suction devices 2 can be pulled outward first to drive another group of extrusion blocks 38 to displace outward. Subsequently, the other group of sliding sleeves 31 can be rotated upward to drive the left end of the other group of sliding sleeves 31 to fit against the left end of the connector 1. After that, the other group of suction devices 2 can be released. Another group of adjusting springs 36 will pull another group of extrusion blocks 38 to drive another group of extrusion blocks 38 to squeeze another group of suction devices 2 so that the right end of the other group of suction devices 2 is inserted into the inner wall of the connector 5. At the same time, another group of positioning rods 37 will be stuck into the inside of the positioning groove 34 to fix the sliding sleeve 31. In this way, the adjustment of the suction device 2 is completed.

[0035] When it is necessary to replace the suction device 2 installed inside the adjustment component 3, the latch 42 can be toggled to the left to drive the latch 42 to move to the left and disengage from the inside of the fixing groove 44. Then, the storage box 35 can be moved forward to disengage from the bottom end of the fixing box 41. At this time, the left end of the suction device 2 will not be fixed. The suction device 2 can be removed to the left and the newly replaced suction device 2 can be inserted into the left end of the sliding sleeve 31. Then, the storage box 35 can be reinstalled along the original path. In this way, the replacement of the suction device 2 is completed.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features.
