When the steel pipe 3 is inserted into the connecting cavity, the fixing member 23 is adapted to be inserted into the fixing portion 31 under the drive of the sliding member 22 to fix the steel pipe 3 .

[0042] The connection structure of the above structure is formed by a plurality of fixing parts 31 provided on the steel pipe 3. In this embodiment, the fixing parts 31 are fixing holes provided on the steel pipe 3. When an external force is applied, the steel pipe 3 can be inserted into the connection cavity. After the steel pipe 3 is inserted into the connection cavity, the sliding member 22 can drive the fixing member 23 to slide in the installation portion in the covering state, and can push part of the fixing member 23 into the connection cavity, while the part of the fixing member 23 extending into the connection cavity will be inserted into the fixing part 31, thereby fixing the steel pipe 3 on the connection member 21, which is beneficial to improve the connection strength between the steel pipe 3 and the connection member 21.

[0043] The connection structure provided in this embodiment is as follows: Figures 1 to 5 As shown, a first plug-in portion 231 and a second plug-in portion 232 are respectively provided on opposite sides of the fixing member 23. In the avoidance state, the first plug-in portion 231 is suitable for abutting against the steel pipe 3, so as to drive the fixing member 23 to move in a direction away from the connecting cavity under the drive of the steel pipe 3, and to make the second plug-in portion 232 extend out of the mounting portion. In the covering state, the second plug-in portion 232 is suitable for abutting against the sliding member 22, so as to drive the fixing member 23 to move in a direction close to the connecting cavity under the drive of the sliding member 22, and to make the first plug-in portion 231 extend out of the mounting portion and be inserted into the fixing portion 31 to fix the steel pipe 3.

[0044] The connection structure of the above structure is through the first plug-in portion 231 and the second plug-in portion 232 provided on the opposite sides of the fixing member 23. In the avoidance state, the first plug-in portion 231 is provided in the connection cavity, and the second plug-in portion 232 is provided in the installation portion, and the steel pipe 3 can be inserted into the connection cavity under the action of external force, thereby contacting the first plug-in portion 231 provided in the connection cavity and squeezing the first plug-in portion 231, thereby pressing the first plug-in portion 231 into the installation portion and pushing the second plug-in portion 232 out of the installation portion. In the covering state, the sliding member 22 slides on the outer peripheral wall surface of the connecting member 21, thereby contacting the second plug-in portion 232 provided outside the installation portion and squeezing the second plug-in portion 232, thereby pressing the second plug-in portion 232 into the installation portion, and pushing the first plug-in portion 231 into the connection cavity and inserting it into the fixing portion 31 provided on the steel pipe 3 to fix the steel pipe 3 and connect and fix the steel pipe 3 to the connecting member 21.

[0045] The connection structure provided in this embodiment is as follows: Figure 4 and Figure 5 As shown, the first plug-in portion 231 and the second plug-in portion 232 are respectively the first plug-in block and the second plug-in block, the side surfaces of the first plug-in block and the second plug-in block are both set to be conical surfaces, and the fixing portion 31 and the plug-in block are conformally matched.

[0046] The connection structure of the above structure is configured such that the first plug-in portion 231 and the second plug-in portion 232 are respectively provided as the first plug-in block and the second plug-in block, and the first plug-in block and the second plug-in block are respectively connected to the opposite sides of the fixing member 23, and the side surfaces of the first plug-in block and the second plug-in block are both set to conical surfaces, so that when the first plug-in block contacts the steel pipe 3 and when the second plug-in block contacts the sliding member 22, the steel pipe 3 and the sliding member 22 can push the fixing member 23 to slide in the installation portion through the conical surface, thereby enabling the first plug-in block to be inserted into the fixing portion 31 on the steel pipe 3 to fix the steel pipe 3 on the connecting member 21. In addition, the fixing portion 31 and the plug-in block are conformally matched, so that the first plug-in block can be inserted into the fixing portion 31 to achieve an interference fit between the first plug-in block and the fixing portion 31, and can improve the connection strength between the first plug-in block and the steel pipe 3.

[0047] The connection structure provided in this embodiment is as follows: Figure 5 As shown, the connecting member 21 is provided with an abutting portion 211, and the sliding member 22 is provided with a sliding portion 221. When the connecting member 21 and the sliding member 22 are connected, the abutting portion 211 is provided in the sliding portion 221, so that when the sliding member 22 slides, the abutting portion 211 is suitable for abutting against the inner wall surface of the sliding portion 221 and limiting the movement of the sliding member 22.

[0048] The connection structure of the above structure is through the abutment portion 211 provided on the connecting member 21 and the sliding portion 221 opened on the sliding member 22. The abutment portion 211 is an abutment block provided on the connecting member 21 in this embodiment, and the sliding portion 221 is a sliding cavity opened on the sliding member 22 in this embodiment. When the connecting member 21 and the sliding member 22 are connected, the abutment portion 211 is provided in the sliding portion 221. Therefore, under the action of external force, when the sliding member 22 slides on the outer peripheral wall surface of the connecting member 21, the abutment portion 211 can also slide in the sliding portion 221. Therefore, when the sliding member 22 moves to the extreme position, the abutment portion 211 will abut against the two opposite inner wall surfaces of the sliding portion 221, thereby limiting the movement of the sliding member 22, so that the sliding member 22 can switch between the avoidance state and the covering state.

[0049] The connection structure provided in this embodiment is as follows: Figure 5 As shown, the connecting assembly 2 further includes an elastic member 24 , which is disposed in the sliding portion 221 , and two ends of the elastic member 24 abut against the inner wall surfaces of the abutting portion 211 and the sliding portion 221 , respectively.

[0050] The connection structure of the above structure also includes an elastic member 24 by setting the connection component 2. The elastic member 24 is a spring in this embodiment. The elastic member 24 is specifically arranged in the sliding part 221, and the two ends of the elastic member 24 are respectively abutted against the inner wall surfaces of the abutting part 211 and the sliding part 221. Therefore, when the sliding member 22 switches from the covering state to the avoidance state, the inner wall surface of the sliding part 221 can squeeze the elastic member 24, so that the elastic member 24 can obtain elastic energy storage. Therefore, when the sliding member 22 switches from the avoidance state to the covering state, the elastic energy stored in the elastic member 24 can assist in pushing the sliding member 22 to move, thereby improving the state switching efficiency of the sliding member 22.

[0051] The connection structure provided in this embodiment is as follows: Figures 1 to 5 As shown, a connecting portion 212 is formed at one end of the connecting member 21 away from the sliding member 22 .

[0052] The connection structure of the above structure is achieved through a connection portion 212 provided at one end of the connection member 21 away from the sliding member 22. The connection portion 212 in this embodiment is a connection hole provided on the connection member 21. The connection portion 212 can be connected to the adapter portion 111, thereby connecting the connection member 21 and the adapter assembly 1 together, and then connecting all the steel pipes 3 connected to the connection member 21 to the adapter assembly 1, making it a whole.

[0053] The connection structure provided in this embodiment is as follows: Figures 1 to 5 As shown, a locking member is further included, which is suitable for passing through the connecting portion 212 and the adapter portion 111 to connect the connecting portion 212 and the adapter portion 111, and to connect the connecting member 21 and the adapter assembly 1.

[0054] The connection structure of the above structure is achieved through a locking member arranged between the connecting portion 212 and the adapter portion 111. The locking member is a screw in this embodiment. When the connecting portion 212 and the adapter portion 111 are connected together, the locking member can pass through the connecting portion 212 and the locking member to connect the connecting member 21 and the adapter assembly 1 together, which is beneficial to improving the connection strength between the connecting member 21 and the adapter assembly 1.

[0055] The connection structure provided in this embodiment is as follows: Figure 1 and Figure 6 As shown, the adapter assembly 1 includes at least three adapters 11 connected to each other. The three adapters 11 are arranged perpendicular to each other in pairs, and an adapter portion 111 is provided on each adapter 11 .

[0056] The connection structure of the above structure is provided with an adapter assembly 1 including three interconnected adapters 11. The adapter 11 in this embodiment is an adapter plate. The three adapters 11 are arranged perpendicular to each other in pairs, and each adapter 11 is provided with a plurality of adapter portions 111, so that the adapter assembly 1 becomes a connection node, and each adapter 11 can be connected to a plurality of connecting members 21, so that the adapter assembly 1 can connect to a sufficient number of steel pipes 3.
