The first adjusting block 551 is fixedly connected with a first rack 553, and the second adjusting block 552 is fixedly connected with a second rack 554; an adjusting gear 555 is rotatably connected in the adjusting cavity, and the adjusting gear 555 is located between the first rack 553 and the second rack 554, and the first rack 553 and the second rack 554 are both meshed with the adjusting gear 555. The first adjusting block 551 is connected with a second spring 556 connected with the extension block 210, and the second adjusting block 552 is connected with a third spring 557 connected with the extension block 210.

[0051] When the synchronization block 49 has not completely entered the synchronization groove, the locking block 51 is engaged with the locking groove on the third rotating shaft 43, the first spring 52, the second spring 556 and the third spring 557 are all in a normal state, the unlocking block 54 does not interfere with the locking block 51, and the end of the positioning block 56 away from the first adjustment block 551 is located in the first through hole of the second rotating shaft 42. When the moving block 29 drives the third rotating shaft 43 to move, the cylindrical block 53 on the synchronization block 49 on the third rotating shaft 43 will pass through the synchronization groove on the second rotating shaft 42 and then enter the first through hole. When the synchronous block 49 is completely located in the synchronous groove, the cylindrical block 53 is completely located in the first through hole, the cylindrical block 53 will conflict with the positioning block 56 and drive the positioning block 56 to move, so that the end of the positioning block 56 away from the first adjusting block 551 is no longer located in the first through hole of the second rotating shaft 42, the positioning block 56 drives the first adjusting block 551 to move, the first rack 553 on the first adjusting block 551 drives the adjusting gear 555 to rotate, the adjusting gear 555 drives the second rack 554 to move, the second rack 554 drives the second adjusting block 552 to move, and the movement direction of the second adjusting block 552 is opposite to that of the first adjusting block 551, the second adjusting block 552 drives the unlocking block 54 to move in the direction close to the locking block 51, the locking block 51 will push the locking block 51 to move, so that the locking block 51 is no longer engaged with the locking groove on the third rotating shaft 43; at this time, the first spring 52 and the second spring 556 are in a compressed state, and the third spring 557 is in a stretched state. When the second rotating shaft 42 rotates, the positioning block 56 abuts against the peripheral side wall of the second rotating shaft 42 .

[0052] refer to Figure 5 and Figure 6 A second clamping mechanism 26 is provided on the first rotating block 31, and a first clamping mechanism 25 is provided on the second rotating block 32. In this embodiment, the first clamping mechanism 25 and the second clamping mechanism 26 have the same structure. Both the first clamping mechanism 25 and the second clamping mechanism 26 include an extension block 251. A slide groove is provided on the extension block 251, and the slide groove is slidably connected with the two clamping blocks 252; a bidirectional screw 254 is rotatably connected to the extension block 251, and the two ends of the bidirectional screw 254 pass through the two clamping blocks 252 respectively, and the two clamping blocks 252 are respectively threadedly connected to the two ends of the bidirectional screw 254; a second motor 253 is fixedly connected to the extension block 251, and the output shaft of the second motor 253 is connected to one end of the bidirectional screw 254. The extension block 251 in the first clamping mechanism 25 is fixedly connected to the second rotating block 32, and the two clamping blocks 252 in the first clamping mechanism 25 clamp the sleeve 18; the extension block 251 in the second clamping mechanism 26 is fixedly connected to the first rotating block 31, and the two clamping blocks 252 in the second clamping mechanism 26 clamp the first catheter 11.

[0053] The second motor 253 is started, and the output shaft of the second motor 253 drives the bidirectional screw 254 to rotate, and the bidirectional screw 254 drives the two clamping blocks 252 to move toward or away from each other.

[0054] In this embodiment, in order to enable the clamping block 252 to better clamp the sleeve 18 and the first conduit 11 , a certain curvature is present at one end of the clamping block 252 away from the extending block 251 .

[0055] The implementation principle of an assembly auxiliary device in an embodiment of the present application is: the operator places the end of the first conduit 11 away from the first connector 13 on the first rotating block 31, and then starts the second motor 253 in the second clamping mechanism 26, so that the two clamping blocks 252 in the second clamping mechanism 26 adjust the position of the first conduit 11 on the first rotating block 31 and clamp the first conduit 11.

[0056] Then the operator places the O-ring 19 in the third placement groove 133 of the first connector 13; then places the third sealing gasket 152 on one side of the second sealing gasket 151 in the second placement groove 132 of the first connector 13, the second sealing gasket 151 contacts the bottom wall of the first placement groove 131 and the shoulder block 102, and the O-ring 19 on the first connector 13 also contacts the second sealing gasket 151. At this time, the insulating gasket 16 on the second sealing gasket 151 contacts the shoulder block 102 on the first connector 13.

[0057] Then place the O-ring 19 in the third placement groove 133 of the second connector 14, move the second connector 14 and the second conduit 12, so that the third sealing gasket 152 on the other side of the second sealing gasket 151 enters into the second placement groove 132 of the second connector 14, the shoulder block 102 on the second connector 14 and the bottom wall of the first placement groove 131 both contact the second sealing gasket 151, and the shoulder block 102 on the second connector 14 presses against the insulating gasket 16.

[0058] Next, the insulating tube 17 is moved from top to bottom, i.e., from the second conduit 12 toward the first conduit 11, so that the end of the insulating tube 17 away from the second conduit 12 abuts against the supporting block 101 on the first connector 13; then, the sleeve 18 is moved from the second conduit 12 toward the first conduit 11, so that the sleeve 18 is sleeved on the insulating tube 17, and the end of the sleeve 18 away from the second conduit 12 abuts against the supporting block 101.

[0059] Then the operator starts the second hydraulic cylinder, which drives the second connection block 23 to move toward the third connection block 27, and the second connection block 23 drives the second rotating block 32 to move toward the third connection block 27, so that the second rotating block 32 presses against the end of the second guide tube 12 away from the second connector 14, and the stabilizing block 24 on the second rotating block 32 presses against the end of the sleeve 18 away from the first guide tube 11; the second motor 253 is started, so that the two clamping blocks 252 in the first clamping mechanism 25 press against the sleeve 18. When the second rotating block 32 on the second connection block 23 presses against the second guide tube 12, the synchronization block 49 on the third rotating shaft 43 on the second connection block 23 enters the synchronization groove of the second rotating shaft 42.

[0060] Then, the first hydraulic cylinder 641 is started to move the lifting block 62 away from the main body 21, and the adjustment shaft 63 drives the first connecting block 22 to rotate, so that the first connecting block 22 changes from a vertical state to a horizontal state, and the first conduit 11 and the second conduit 12 also change from a vertical state to a horizontal state.

[0061] Then, the first motor 48 is started to make the first rotating block 31 and the second rotating block 32 rotate synchronously, and the first conduit 11, the second conduit 12 and the sleeve 18 rotate synchronously; then the operator performs groove welding on the part where the sleeve 18 and the supporting block 101 conflict with each other.

[0062] After the welding of the sleeve 18 and the supporting block 101 is completed, the first hydraulic cylinder 641 is started again to change the first conduit 11 and the second conduit 12 from a horizontal state to a vertical state; finally, the operator pours epoxy resin between the sleeve 18 and the second conduit 12 so that the epoxy resin forms an insulating filling layer between the sleeve 18 and the second conduit 12.

[0063] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
