This structure can change the previous cutting opening method, which can save manpower and material resources. At the same time, this structure can also avoid the deterioration of the anti-deformation ability and structural strength of the square-mouthed tube due to the side wall notch, which is more convenient for transportation and transfer, avoids damage, and has strong practicality.

[0021] In some embodiments, the locking portion 12 may be configured as follows: Figure 1 See the structure shown. Figure 1The locking part 12 includes a bottom rod 121 arranged along the second direction, two top rods 122 are arranged above the bottom rod 121, the two top rods 122 are arranged along the second direction, a notch is formed between the two top rods 122, and the opposite ends of the two top rods 122 are connecting ends. A support rod 123 is arranged between each top rod 122 and the bottom rod 121.

[0022] The bottom bar 121 is mainly used for support, and the axes of the two top bars 122 on the bottom bar 121 are arranged in a colinear manner, which can ensure that a gap is formed between the two, so as to facilitate the connection of the connecting structure 20. The support rod 123 can ensure the support of the two top bars 122, thereby ensuring the stability of the two support rods 123. The locking portion 12 formed by the combination of the bottom bar 121, the top bar 122 and the support rod 123 has a simple structure and is easy to manufacture. In addition, since the bottom bar 121, the top bar 122 and the support rod 123 are all assembled by combination, two short top bars 122 are provided, which can avoid the time and effort caused by the cut, and at the same time, this structure can also avoid problems such as damage due to transportation or transfer.

[0023] It should be noted that the connection between the bottom rod 121, the top rod 122 and the support rod 123 may be a threaded connection.

[0024] In some embodiments, the frame 10 may be configured as follows: Figure 1 See the structure shown. Figure 1 The frame 10 further includes an intermediate connecting portion 13, which is used to fix the bottom rod 121 and each top rod 122. The intermediate connecting portion 13 is located between the adapter portion 11 and the locking portion 12, and the intermediate connecting portion 13, the adapter portion 11 and the locking portion 12 enclose a storage space.

[0025] The intermediate connecting part 13, the locking part 12 and the connecting part are combined to form a storage space, thereby satisfying the storage function.
