Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention can be embodied in many different forms other than those specifically described herein, and it will be apparent to those skilled in the art that similar modifications can be made without departing from the spirit and scope of the invention, and it is therefore not to be limited to the specific embodiments disclosed below.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

A diagonal member connecting device comprises a first element 1 and a second element 2, wherein the first element 1 is used for being connected with a bracket 5. In some embodiments, the bracket 5 is provided with a fixing plate 501, the fixing plate 501 is provided with a plurality of mounting holes 502 in the circumferential direction, and the first element 1 is inserted into the mounting holes 502.

The second element 2 has a first section 201 and a second section 202, the first section 201 and the second section 202 being connected. In some embodiments, the first section 201 and the second section 202 are integrally formed. In other embodiments, the first section 201 and the second section 202 are fixedly connected, such as welded or screwed. The first section 201 is provided with a first hole 203, at least four second elements 2 are sleeved on the first element 1 through the first hole 203, and at least two second sections 202 of the second elements 2 face upward, wherein the upward direction comprises a vertical upward direction and an oblique upward direction. The second sections 202 of at least two of the second elements 2 are directed downward, and the downward direction includes a vertical downward direction and an obliquely downward direction. The second element 2 is rotatable relative to the first element 1.
