Further in combination with Figure 8 , Figure 9 , Figure 11 and Figure 12 , the second supporting portion 21 is provided with a second supporting surface 22, the second supporting surface 22 is a convex arc surface.

[0076] In Figures 8 to 10 , the rod member 7 is in the retracted position. In Figure 11 and Figure 12 , the rod member 7 is in the process of transforming from the retracted position to the extended position, the process of transforming from the extended position to the retracted position is the reverse process of transforming from the retracted position to the extended position, hereinafter the description of transforming from the retracted position to the extended position can be reversed to transforming from the extended position to the retracted position, and vice versa.

[0077] As shown in Figure 8 and Figure 9As shown in the figure, when the rod 7 is in the retracted position, the rod 7 is located in the central cavity 10, and part or all of the rod 7 is located in the central cavity 10. In the embodiment shown in the figure, part of the rod 7 is located in the central cavity 10. The fifth side wall 17 faces the opening 13, and part of the fifth side wall 17 can extend into the opening 13. The second support portion 21 protrudes vertically downward from the rod 7, and the second support portion 21 protrudes vertically at the bottom end of the rod 7, which makes the second support surface 22 protrude vertically at the bottom end of the rod 7, so that the second support surface 22 can be in contact with the first support surface 16 when the rod 7 is extended from the retracted position as described later. When the rod 7 is in the retracted position, the convex arc surface of the second support surface 22 faces the first side wall 8 and the vertically downward side, and the normal line from any point on the convex arc surface points to the first side wall 8 and / or the vertically downward side, that is, the normal line from any point on the convex arc surface is perpendicular to the first side wall 8, or extends vertically downward, or extends obliquely within the range of being perpendicular to the first side wall 8 to extending vertically downward, which makes the second support surface 22 can slide with the first support surface 16 when the rod 7 is extended from the retracted position as described later.

[0078] As shown in the figure, Figure 11 and Figure 12 When the rod 7 is extended from the retracted position, the rod 7 rotates towards the opening 13, the fifth side wall 17 is supported by the second side wall 9 on the vertically downward side of the opening 13, and the rod 7 rotates around the second side wall 9 on the vertically downward side of the opening 13 as the fulcrum, the second support surface 22 is supported by the first support surface 16, and the first support surface 16 guides the second support surface 22 to slide along the first support surface 16, which makes the rod 7 rotate and extend smoothly from the opening 13 of the pipe 1 with less effort.

[0079] As shown in the figure, Figure 4 and Figure 5 The second side wall 9 can be provided with a third support surface 23 on the vertically downward side of the opening 13, the third support surface 23 is a convex arc surface and faces the first side wall 8 and the vertically upward side, and the normal line from any point on the convex arc surface is perpendicular to the first side wall 8, or extends vertically upward, or extends obliquely within the range of being perpendicular to the first side wall 8 to extending vertically upward. The third support surface 23 can be provided at the edge of the second side wall 9 at the bottom end of the opening 13, and extends from the edge of the second side wall 9 at the bottom end of the opening 13 to the inner wall surface of the second side wall 9. As shown in the figure, Figure 6 The fifth side wall 17 can be provided with a fourth support surface 24. As shown in the figure, Figure 8 and Figure 9 When the rod 7 is in the retracted position, the fourth support surface 24 faces the second side wall 9, and the fourth support surface 24 is located on the inner side of the second side wall 9. The fourth support surface 24 can be a plane, and the normal line from the fourth support surface 24 is perpendicular to the second side wall 9. As shown in the figure, Figure 11 and Figure 12As shown, when the rod 7 is extended from the stowed position, the rod 7 is rotated towards the opening 13, the fourth bearing surface 24 is supported by the third bearing surface 23, and the fourth bearing surface 24 is rotated on the third bearing surface 23, so that the rod 7 is smoothly and labor-savingly rotated and extended from the opening 13 of the tube 1.

[0080] As shown, Figure 4 and Figure 5 As shown, the tube 1 can be provided with a second limiting groove 25 on one or both lateral sides of the central cavity 10, and in the illustrated embodiment, the second limiting groove 25 is provided on both lateral sides of the central cavity 10, and the second limiting groove 25 is provided on the third side wall 11 and the fourth side wall 12. The tube 1 is provided with a top opening 14 at the top end, and the second limiting groove 25 extends vertically downward from the mouth 27 of the top opening 14. Figure 6 and Figure 7 As shown, the rod 7 is provided with a crown 26 at the top end, and the crown 26 is provided with a second limiting member 28 on one or both lateral sides of the rod 7, and in the illustrated embodiment, the second limiting member 28 is provided on both lateral sides of the rod 7. As shown, Figure 8 and Figure 9 As shown, when the rod 7 is in the stowed position, the crown 26 protrudes laterally from the rod 7, so that the crown 26 is supported by the mouth 27 of the top opening 14, and the second limiting member 29 protrudes vertically downward from the crown 26 and is inserted into the second limiting groove 25, and the second limiting groove 25 blocks the second limiting member 28, which prevents the rod 7 from being rotated and extended from the stowed position to the opening 13, so that the rod 7 is maintained in the stowed position. As shown, Figure 11 and Figure 12 As shown, when the rod 7 is extended from the stowed position, the rod 7 needs to be moved vertically upward before being rotated towards the opening 13, so that the crown 26 is moved away from the mouth 27 of the top opening 14 and the second limiting member 28 is disengaged from the second limiting groove 25, so as to allow the rod 7 to be rotated and extended towards the opening 13, and then the rod 7 is rotated towards the opening 13. The second limiting groove 25 and the second limiting member 28 can be configured such that the rod 7 is moved vertically upward by 15 mm to disengage the second limiting member 28 from the second limiting groove 25, so that the lifting stroke of the rod 7 is short, convenient, fast and labor-saving. The vertical depth of the second limiting groove 25 can be 15 mm, and the vertical height of the second limiting member 28 can be 15 mm.

[0081] As shown, Figure 4 and Figure 5As shown, the second limiting groove 25 can be provided with a first limiting face 29 and a second limiting face 30. The first limiting face 29 extends towards the first side wall 8 and along the vertical direction, and the first limiting face 29 can be a flat face, and a normal line from the first limiting face 29 is perpendicular to the first side wall 8. The second limiting face 30 is a concave arc face and faces towards the second side wall 9 and the vertical upper side, and a normal line from any point of the concave arc face is perpendicular to the second side wall 9, or extends upwards along the vertical direction, or extends obliquely within the range from perpendicular to the second side wall 9 to upwards along the vertical direction. As shown, Figure 6 and Figure 7 As shown, the second limiting member 28 can be provided with a first limiting face cooperating face 31 and a second limiting face cooperating face 32. As shown, Figure 8 and Figure 9 As shown, when the rod member 7 is in the stowed position, the first limiting face cooperating face 31 extends along the vertical direction and abuts against the first limiting face 29, and the first limiting face cooperating face 31 can be a flat face. The second limiting face cooperating face 32 is a convex arc face and faces towards the first side wall 8 and the vertical lower side, and a normal line from any point of the convex arc face is perpendicular to the first side wall 8, or extends upwards along the vertical direction, or extends obliquely within the range from perpendicular to the first side wall 8 to upwards along the vertical direction, and the second limiting face cooperating face 32 is supported by and abuts against the second limiting face 30. The cooperation between the first limiting face cooperating face 31 and the first limiting face 29 and the cooperation between the second limiting face cooperating face 32 and the second limiting face 30 enable the second limiting member 28 to be stably retained in the second limiting groove 25, thereby enabling the rod member 7 to be stably retained in the stowed position.

[0082] As shown, Figure 4 and Figure 5 As shown, the mouth edge 27 of the top end opening 14 can be provided with a chamfer 33 at the second side wall 9, and the chamfer 33 provides a slope at the joint between the mouth edge 27 of the top end opening 14 and the second side wall 9. As shown, Figure 11 and Figure 12 As shown, during the process of rotating the rod member 7 towards the opening 13 and thereby rotating from the extended position to the stowed position, the second limiting face cooperating face 32 is supported by the chamfer 33, and the second limiting face cooperating face 32 slides on the slope of the chamfer 33, and the chamfer 33 guides the second limiting face cooperating face 32 to slide obliquely upwards, which is convenient, fast and labor-saving.

[0083] As shown, Figure 4 and Figure 5 As shown, the tubular member 1 can be provided with a first limiting groove 34 at one or both lateral sides of the central cavity 10, and the first limiting groove 34 extends along the vertical direction, and in the illustrated embodiment, the first limiting groove 34 is provided at both lateral sides of the central cavity 10, and the first limiting groove 34 is provided at the third side wall 11 and the fourth side wall 12. As shown, Figure 6 and Figure 7As shown, the rod 7 can be provided with a first limiting member 35 on one or both sides of the lateral direction. The first limiting member 35 protrudes laterally from the rod 7. In the illustrated embodiment, the first limiting member 35 is provided on one side of the lateral direction of the rod 7. Therefore, the first limiting groove 34 on one side of the central cavity 10 does not play a limiting role. The first limiting member 35 can be a limiting rod. Figure 8 and Figure 10 As shown, during the process of the rod 7 being in the extended position, the retracted position, or the change between the retracted position and the extended position, the first limiting member 35 is always inserted into the first limiting groove 34. The first limiting groove 34 blocks the first limiting member 35, preventing the first limiting member 35 from coming out of the first limiting groove 34, thereby preventing the rod 7 from coming out of the tube 1 and avoiding the rod 7 from coming out of the tube 1.

[0084] like Figure 8 and Figure 9 As shown, when the rod 7 is in the retracted position, there can be a longitudinal gap between the fourth support surface 24 and the second side wall 9, which is less than or equal to 1.5 mm. This allows the second side wall 9 to limit the fourth support surface 24 and prevent the rod 7 from shaking too much inside the tube 1.

[0085] like Figure 8 and Figure 9 As shown, when the rod 7 is in the retracted position, the sixth side wall 19 can face the first side wall 8. The sixth side wall 19 is located inside the first side wall 8, and there can be a longitudinal gap between the sixth side wall 19 and the first side wall 8. The longitudinal gap is less than or equal to 2 mm. This allows the first side wall 8 to limit the sixth side wall 19, preventing the rod 7 from shaking too much in the tube 1, and making the rod 7 move smoothly in the tube 1 when it is moved vertically upward, making the operation convenient and labor-saving.

[0086] like Figure 6 and Figure 7 As shown, a second support portion 21 can be provided on each of the two lateral sides of the rod 7. When the rod 7 rotates and extends into the opening 13, the rod 7 is supported on the first support surface 16 by the second support surface 22 on both lateral sides, providing stable support. Each second support portion 21 protrudes laterally from the rod 7. One second support portion 21 can protrude laterally into the seventh side wall 19, and the other second support portion 21 can protrude laterally into the eighth side wall 20. There is a lateral gap between the second support portion 21 and the tube 1, which is less than or equal to 2 mm. This allows the tube 1 to limit the second support portion 21, preventing the rod 7 from swaying too much within the tube 1, and also allowing the rod 7 to move smoothly within the tube 1 when it is moved vertically upwards and rotated out, making operation convenient and effortless. The lateral gap is located between the lateral end face of one second support portion 21 and the third side wall 11, and also between the lateral end face of the other second support portion 21 and the fourth side wall 12.

[0087] As Figures 1 to 5 , Figures 8 to 12 shown, the pipe fitting 1 can be provided with a tapered boss foot 36 at the bottom end, and when the plurality of turnover feet are stacked up and down for storage, the upper tapered boss foot 36 can be inserted into the central cavity 10 of the lower pipe fitting 1, thereby saving space. The tapered boss foot 36 can be provided with a hole communicating with the central cavity 10, which is beneficial to drain the water in the central cavity 10 of the pipe fitting 1.
