[0028] The following further describes the present utility model with reference to the drawings:

[0029] Embodiment 1: As Figures 1 - 6 shown, an EP pipe diameter conversion table includes a mounting base 1. At least three mounting grooves 2 are provided on the mounting base 1. A slider 3 is provided in the mounting groove 2. A fixing rod 5 is connected to the slider 3. The middle part of the fixing rod 5 is hinged to the slider 3. A protective cover 6 is further provided on the top of the fixing base. A ring plate 7 and a spring 8 are provided in the protective cover 6. The spring 8 is located above the ring plate 7.

[0030] As Figure 5 shown, a connecting groove 13, a fixing shaft 14, a limiting block 16, and a guiding surface 17 are provided on the slider 3. The fixing shaft 14 is located in the connecting groove 13. The number of the limiting blocks 16 is two and they are respectively fixed on a group of opposite side walls of the slider 3. With such a setting, the fixed connection between the mounting base 1 and the vacuum concentrator can be realized through the slider 3.

[0031] As Figure 4 and Figure 5As shown, limiting grooves 9 are respectively arranged on a set of opposite side walls of the installation groove 2, and the two limiting blocks 16 are respectively located in the limiting grooves 9 in one-to-one correspondence. Such a setting can fix the slider 3 in the installation groove 2, and at the same time, it will not affect the sliding of the slider 3.

[0032] Specifically, a protective tube 10 is fixedly arranged on the protective cover 6, and a plurality of sliding grooves 11 are arranged on the protective tube 10. Such a setting can protect the spring 8 in the protective cover 6 and prevent sundries from entering and affecting the use.

[0033] As Figure 1 and Figure 6 As shown, a connecting rod 4 is fixedly arranged in the middle of the fixing rod 5, a connecting hole 15 is arranged on the connecting rod 4, the connecting hole 15 is matched with the fixing shaft 14, and one end of the fixing rod 5 passes through the sliding groove 11, and the other end is attached to the bottom of the ring plate 7. Such a setting can realize the connection between the fixing rod 5 and the slider 3.

[0034] The working process of this embodiment: When in use, first insert the mounting seat 1 into the placement hole on the vacuum concentrator for fixing the low adsorption tube 12. When inserting the mounting seat 1 into the placement hole, the guiding surface 17 on the slider 3 will contact the edge of the placement hole and push the slider 3 to retract into the mounting seat 1. After the mounting seat 1 is installed in the placement hole, then insert the small-diameter low adsorption tube 12 into the mounting seat 1. When the low adsorption tube 12 is inserted, the low adsorption tube 12 will push down one end of the fixing tube. When one end of the fixing rod 5 that contacts the low adsorption tube 12 just starts to move downward, the fixing rod 5 will push the slider 3 to move out of the mounting seat 1 through the connection. The slider 3 moves outward from the mounting seat 1. When the slider 3 contacts the inner wall of the placement hole on the vacuum concentrator, it will stop moving. When the slider 3 stops moving, as the end that contacts the low adsorption tube 12 continues to move downward, the other end of the fixing rod 5 will start to move upward. When the other end of the fixing rod 5 moves upward, it will push the ring plate 7 to move upward. When the ring plate 7 moves upward, it will compress the spring 8. At this time, the slider 3 will also be subjected to the thrust from the fixing rod 5, and the slider 3 will be extruded against the inner wall of the placement hole on the vacuum concentrator, improving the connection stability between the mounting seat 1 and the placement hole on the vacuum concentrator. At the same time, after the bottom of the low adsorption tube 12 passes through between the ends of multiple fixing rods 5, since all the fixing rods 5 will be subjected to the pressure exerted by the ring plate 7, the forces exerted by all the fixing rods 5 on the low adsorption tube 12 are all equal, so as to stably support and fix the low adsorption tube 12, facilitating the operation of the vacuum concentrator.

[0035] After use, the staff lifts the low adsorption tube 12 upward. The end of the fixing rod 5 that contacts the low adsorption tube 12 will always be in contact with the low adsorption tube 12 during this process. However, at the same time, the slider 3 will move into the mounting seat 1, and at the same time, the spring 8 will elongate and push the ring plate 7 to move downward until the fixing rod 5 moves to as Figure 2After reaching the horizontal state, the fixed rod 5 will stop moving. At this time, the low adsorption tube 12 will be pulled out from between the fixed rods 5.

[0036] The above has described an embodiment of the present invention in detail, but the content is only the preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
