Because the long pole 5 is arranged in the long pole connector cavity 202, the cantilever connector cavity 302 is arranged in the cantilever connector cavity 6, and the vertical pole 4 is arranged in the vertical pole connector cavity 101, the pin 7 connects the three poles together to form a three-pole cantilever structure.

[0023] Depend on Figure 1 , Figure 2 and Figure 3 It can be known that in this embodiment of the utility model, the vertical pole connector 1 is divided into two parts, upper and lower, with the vertical pole connector pin hole 17 and the pin shaft 7 as the axis.

The cantilever rod connector 3 is provided with a cantilever rod connector cavity 302 at the end away from the cantilever rod connector protrusion 301. The cantilever rod connector cavity 302 is similar to the vertical pole connector cavity 101. The cantilever rod connector cavity 302 is used to install the cantilever rod 6.

[0024] In this embodiment of the utility model, by Figure 1 , Figure 2 and Figure 3It can be seen that the utility model discloses a three-rod cantilever structure, including a pin shaft 7. The structure of the utility model is based on the pin shaft 7 as the main axis, and its main installation process can be roughly summarized as the following steps. First, the long rod connector 2 and the long rod connector protrusion 201 provided on one side of the long rod connector 2 are placed into the long rod connection cavity 8 in the vertical rod connector 1, so that the long rod connector protrusion pin hole 9 provided on the long rod connector protrusion 201 corresponds to the vertical rod connector pin hole 17 on the vertical rod connector 1. Then, insert the lifting rod connector protrusion 301 on one side of the lifting rod connector 3 into the accommodating cavity 11 of the long rod connector protrusion 201 on one side of the long rod connector 2, so that the lifting rod connector protrusion 301 on one side of the lifting rod connector 3 corresponds to the connecting plate 12 in the accommodating cavity 11, and further, make the lifting rod connector protrusion pin hole 10 on the lifting rod connector protrusion 301 on one side of the lifting rod connector 3 correspond to the connecting plate pin hole 13 on the connecting plate 12 in the accommodating cavity 11. Finally, pass the pin shaft 7 through the vertical pole connector pin hole 17, the long pole connector protrusion pin hole 9, the connecting plate pin hole 13, the lifting rod connector protrusion pin hole 10 on one side, and the connecting plate pin hole 13, the long pole connector protrusion pin hole 9 and the vertical pole connector pin hole 17 on the other side in sequence to complete the fixation. That is, the vertical pole connector 1, the long pole connector 2 and the lifting rod connector 3 are connected together through the pin shaft 7. After the connection of the vertical pole connector 1, the long pole connector 2 and the cantilever connector 3 is completed, the corresponding three poles, namely the vertical pole 4, the long pole 5 and the cantilever connector 6, are respectively inserted into the corresponding vertical pole connector cavity 101, the long pole connector cavity 202 and the cantilever connector cavity 302 to complete the fixation. More specifically, the long pole 5 and the long pole connector cavity 202 use screws 14 to fix the long pole 5 and the long pole connector 2 together, and the vertical pole 4 and the vertical pole connector cavity 101 use connecting screws 16 to fix the vertical pole 4 and the vertical pole connector 1 together. When the vertical pole 4, the long pole 5 and the cantilever connector 6 are installed, it means that the three-rod cantilever structure described in the utility model is assembled. For disassembly and replacement, the vertical pole 4, the long pole 5 and the cantilever connector 6 are removed first, and then the pin shaft 7 is pulled out to take out the vertical pole connector 1 and the long pole connector 2. If replacement is required, disassemble and replace as described above. The simplest replacement is to replace the pin shaft 7. The pin 7 is the main axis of rotation and is therefore the most worn. Therefore, for the sake of work efficiency, its replacement is the simplest. You only need to pull it out and replace it with the new pin 7. If the vertical rod 4, long rod 5, and lifting rod 6 are worn and need to be replaced, it is also very simple. You only need to release the connection between the three rods and the corresponding vertical rod connector cavity 101, long rod connector cavity 202, and lifting rod connector cavity 302.Take the long rod 5 as an example. If the long rod 5 needs to be replaced, the screw 14 is screwed out to release the connection between the long rod 5 and the long rod connector 2. Specifically, the connection between the long rod 5 and the long rod connector cavity 202 is released. The old long rod 5 is replaced with a new long rod 5. The new long rod 5 is inserted into the long rod connector cavity 202 and the screw 14 is screwed back on to complete the replacement of the long rod 5. The same is true for the vertical pole 4. If the vertical pole 4 needs to be replaced, the connection screw 16 is screwed out to release the connection between the vertical pole 4 and the vertical pole connector 1. Specifically, the connection between the vertical pole 4 and the vertical pole connector cavity 101 is released. The old vertical pole 4 is replaced with a new vertical pole 4. The new vertical pole 4 is inserted into the vertical pole connector cavity 101 and the connection screw 16 is screwed back on to complete the replacement of the vertical pole 4.

[0025] In this embodiment of the utility model, by Figure 4 Combination Figure 1 It is known that in Figure 4 The middle pole connector 1 can be regarded as the pole connector pin hole 17 which divides the internal cavity of the pole connector 1 into the upper long pole connector cavity 8 for preventing the long pole connector 2 and the long pole connector protrusion 201 from being moved and the lower connecting cavity 15. Figure 1 The first open state of the three-rod cantilever structure is standardly recorded, at which time the bottom surface of the accommodating cavity 11 and the cantilever rod connector 3 are in the same straight line, the accommodating cavity 11 and the long rod connector 2 are at an angle, and the long rod connector 2 is completely in the long rod connector cavity 8, and the back of the long rod connector 2 with the screw 14 is completely against the long rod connector cavity 8, that is, it is close to the long rod connector cavity 8. In addition, Figure 1 It can be seen that Figure 1 To show that in the first open state, the angle formed by the lifting rod 6 and the connecting cavity 15 is approximately a right angle. Of course, the beneficial effect of the utility model is that the clamping and pinning between the three rods cooperate with each other, making the connection between the three rods more stable, and the long rod connecting cavity is added to the structure to accommodate the lifting rod, saving storage space and making the storage more compact. Specifically, when the three-rod cantilever structure is folded, the lifting rod 6 can be rotated about the pin shaft 7 as the axis so that the lifting rod connector 3 is stored in the corresponding accommodating cavity 11, thereby saving storage space. Similarly, the vertical rod 4 can be rotated about the pin shaft 7 as the axis so that it is folded upward, and when it is folded downward, the lifting rod 6 is rotated about the pin shaft 7 as the axis so that the lifting rod connector 3 is stored in the corresponding connecting cavity 15, thereby saving storage space.
