[0032] Argon gas cylinder 4, the argon gas cylinder 4 is communicated with the glove box 2 through a gas pipe 41;

[0033] Among them, after the EP tube is sleeved with a ferrule, it is arranged in the middle position inside the main body 1, and the length of the main body 1 is greater than the length of the EP tube.

[0034] Select a main body 1 that is slightly longer than the EP tube, place it on the bracket 5 after straightening it spirally, sleeve the EP tube with a ferrule and arrange it in the middle position inside the main body 1. Fix and install glove boxes 2 on both sides of the main body 1 respectively, connect the endoscope 3 wire and the trachea 41 to the glove box 2, turn on the argon gas for purging, and manipulate the rubber gloves 21 in the glove box 2 to open the tube cap of the internal EP tube, and put the endoscope 3 for inspection.

[0035] Through the set structure of the main body 1 and the setting of the glove box 2, the safe and effective inspection and operation of the inside of the EP tube are realized in an environment without a clean room.

[0036] In this embodiment, a groove 13 is provided at the edge of the main body 1, and a rubber ring 13A is arranged in the groove 13, and the rubber ring 13A is used to maintain the seal.

[0037] A groove 13 is provided at the edge of the main body 1, and a rubber ring 13A is installed in the groove 13, effectively enhancing the sealing performance of the entire tooling. Through the sealing effect of the rubber ring 13A, it can effectively prevent external dust, moisture and other impurities from entering the inside of the tooling, thereby protecting the internal environment from pollution.

[0038] In this embodiment, a plurality of brackets 5 are provided at the lower part of the main body 1, and the brackets 5 are arranged in a three-leg support form.

[0039] A plurality of brackets 5 are provided at the lower part of the main body 1, and these brackets 5 are in a three-leg support form, providing stable support and good balance. The three-leg support form increases the grounding area of the tooling, thereby improving the overall stability, reducing the operation error caused by the shaking of the tooling, ensuring the stability and safety of the equipment during the operation process, helping to maintain the horizontal state of the tooling, and improving the accuracy and reliability during use.

[0040] In this embodiment, the material of the bracket 5 is selected as stainless steel.

[0041] The material of the bracket 5 is selected as stainless steel, which endows the bracket 5 with high corrosion resistance and strength. The use of stainless steel not only enhances the structural stability of the bracket 5, but also provides long-term durability and ease of maintenance.

[0044] In this embodiment, the connection between the main body 1 and the glove box 2 is set as a flexible connection part 6, and the material of the flexible connection part 6 is selected as transparent PE.

[0045] The transparent PE material not only has good flexibility, which can provide the necessary range of motion at the connection, but also allows the operator to directly observe the state of the connection part, thus better monitoring and ensuring the safety of the operation. The chemical resistance and weather resistance of the PE material ensure that the connection part can maintain good performance in various environments. At the same time, the tear resistance of this material also guarantees the durability of the connection, further enhancing the reliability and service life of the entire tooling.

[0046] In this embodiment, the material of the main body 1 is selected as transparent PVC.

[0047] The transparent PVC material enables the operator to directly observe the inside of the main body 1, which is helpful for the inspection operation of the EP pipeline. Moreover, the PVC material itself has good chemical stability and physical durability, making it suitable for use in a variety of industrial environments. Its waterproof and corrosion-proof characteristics also ensure the structural integrity and performance maintenance during long-term use, thereby improving the reliability of the tooling and the convenience of maintenance.

[0048] In this embodiment, for the EP pipeline inspection, argon gas is first used for purging, and then the tube cap is opened to insert the endoscope 3 for inspection.

[0049] When performing EP pipeline inspection, first purge with argon gas through the argon gas cylinder 4, and then open the pipe cap and put the endoscope 3 to conduct the inspection. Argon gas purging can effectively remove impurities and residues inside the EP pipeline. Such a cleaning step can ensure the accuracy of the inspection.
