Description

Technical Field

[0002] In engineering construction, tunnel construction problems are often encountered. In the process of long tunnel construction, two drilling rigs are usually used for opposite construction to ensure stable drilling and save construction time.

In each of the accompanying drawings, the same elements are represented by the same or similar reference numerals. For the sake of clarity, the various parts in the accompanying drawings are not drawn to scale. In addition, some well-known parts may not be shown in the drawings.

[0054] The specific implementation of the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. Many specific details of the utility model are described below, such as the structure, material, size, processing technology and technology of the components, so as to more clearly understand the utility model. However, as those skilled in the art can understand, the utility model can be implemented without following these specific details.

[0055] It should be understood that when describing the structure of a component, when a layer or a region is referred to as being "on" or "over" another layer or another region, it may mean that it is directly on the other layer or another region, or that other layers or regions are included between it and the other layer or another region. Moreover, if the component is turned over, the layer or a region will be "below" or "beneath" another layer or another region.

The multiple magnetic connectors are connected in sequence, and the adjacent magnetic connectors are connected by the male buckle 230 and the female buckle 240.

[0077] In the above-mentioned embodiments of the present invention, the number of magnetic joints can be flexibly set, so that the number of magnets can be adjusted and the setting of the magnetic field can be flexibly achieved.

[0078] Optionally, the magnetic joint further includes a male buckle positioning member and a female buckle positioning member. The male buckle positioning member is arranged on the male buckle 230 and / or arranged on one side of the male buckle 230.
