[0030] In the embodiments of the present disclosure, as Figures 4 - 6As shown in the figure, a notch groove is provided at the top of the composite pipe fixing plate 7, and the width and height of the notch groove are both equal to the outer diameter of the composite pipe. During use, the composite pipe to be welded can be placed in the notch groove at the top of the composite pipe fixing plate 7, and then the composite pipe locking ring 8 is rotated 180°. At this time, the composite pipe locking ring 8 can lock the composite pipe inside the composite pipe fixing plate 7 to prevent the composite pipe from shaking, and then the composite pipe can be welded.
[0031] In the embodiment of the present disclosure, as Figures 1 - 3 shown, semi-circular notch grooves are provided on both the left and right sides at the top of the composite pipe welding box 2, and semi-circular notch grooves are also provided on both the left and right sides at the bottom of the welding box cover 3.

During use, the composite pipe to be welded can be placed in the semi-circular notch grooves on both the left and right sides at the top of the composite pipe welding box 2, and then the welding box cover 3 is rotated forward to close. At this time, the semi-circular notch grooves on both the left and right sides at the bottom of the welding box cover 3 will be in close contact with the outer wall of the composite pipe. Therefore, the composite pipe welding box 2 and the welding box cover 3 can cooperate to clamp and fix the composite pipe, and if there is a situation of material spraying during welding, it will also be blocked by the composite pipe welding box 2 and the welding box cover 3.
[0032] In the embodiment of the present disclosure, as Figures 4 - 6 shown, an annular groove is provided on the outside of the composite pipe fixing plate 7. The composite pipe locking ring 8 can rotate in this annular groove, and an opening is also provided on the composite pipe locking ring 8. During use, the composite pipe locking ring 8 can be rotated on the outside of the composite pipe fixing plate 7 to rotate the opening on the composite pipe locking ring 8 to the uppermost position. At this time, the notch groove at the top of the composite pipe fixing plate 7 will be in an open state, and then the composite pipe to be welded can be placed in the notch groove at the top of the composite pipe fixing plate 7.
[0033] In the embodiment of the present disclosure, as Figures 1 - 3 shown, the supporting block 4 is composed of two sector plates. The outer diameter of the sector plate at the rear of the supporting block 4 is equal to the inner diameter of the box cover locking ring 5, and the outer wall of the rear side of the sector plate at the front of the supporting block 4 is in close contact with the front outer wall of the box cover locking ring 5.

When the fusion welding box lid 3 is rotated to the closed state, the inner wall of the lid locking ring 5 can be closely attached to the outer wall of the lid locking rod 6. When the fusion welding box lid 3 needs to be opened or closed, the lid locking ring 5 can be rotated outside the support block 4 and the opening on the lid locking ring 5 can be rotated to the uppermost position. When the fusion welding box lid 3 is opened, the lid locking rod 6 on the front side thereof will be disengaged from the lid locking ring 5 through the opening on the lid locking ring 5. When the fusion welding box lid 3 is closed, the lid locking rod 6 on the front side thereof will be moved back to the inside of the lid locking ring 5 through the opening on the lid locking ring 5.
[0035] Embodiment 2. On the basis of Embodiment 1, as Figures 1 - 6 shown in the figure, a glass window is provided on the fusion welding box lid 3. A cylindrical rod is provided on the outside of both the lid locking ring 5 and the composite pipe locking ring 8. When fixing the composite pipe, the electrofusion fitting connected to the composite pipe can be located inside the composite pipe fusion welding box 2.

At this time, the fusion welding box lid 3 can be rotated backward to be opened. When the fusion welding box lid 3 is opened, the lid locking rod 6 on the front side thereof will be disengaged from the lid locking ring 5 through the opening on the lid locking ring 5. Then rotate the composite pipe locking ring 8 outside the composite pipe fixing plate 7 and rotate the opening on the composite pipe locking ring 8 to the uppermost position. At this time, the notch groove at the top of the composite pipe fixing plate 7 will be in an open state. Then the composite pipe to be welded can be placed in the notch groove at the top of the composite pipe fixing plate 7 and the semi-circular notch grooves on the left and right sides at the top of the composite pipe fusion welding box 2, and the electrofusion fitting connected to the composite pipe is located inside the composite pipe fusion welding box 2. Then rotate the fusion welding box lid 3 forward to close it. During this process, the lid locking rod 6 on the front side of the fusion welding box lid 3 will be moved back to the inside of the lid locking ring 5 through the opening on the lid locking ring 5. Then rotate the lid locking ring 5 by 180° to lock the fusion welding box lid 3. Moreover, at this time, the semi-circular notch grooves on the left and right sides at the bottom of the fusion welding box lid 3 will also be closely attached to the outer wall of the composite pipe. Therefore, the composite pipe fusion welding box 2 and the fusion welding box lid 3 can cooperate to clamp and fix the composite pipe. Then rotate the composite pipe locking ring 8 by 180° as well. At this time, the composite pipe locking ring 8 can lock the composite pipe inside the composite pipe fixing plate 7 to prevent the composite pipe from shaking. Then the composite pipe can be welded. If there is a situation of spraying materials during welding, it will also be blocked by the composite pipe fusion welding box 2 and the fusion welding box lid 3.
