Description

Technical Field

[0001] This utility model belongs to the field of mechanical connection technology, and specifically relates to a connection device. Background Technology

[0002] Bolts are commonly used connecting components, usually in conjunction with nuts. The most common type of bolt is the straight bolt, used to connect two or more structural features on the same straight line. For structural features that are not on the same straight line, straight bolts cannot be used directly. If straight bolts are used, the dimensions of the structures to be connected must be adjusted during the initial design phase. This changes the original dimensions of the structures to be connected, potentially altering their performance, which is quite troublesome. Currently, it is necessary to develop a new type of connecting device to connect structural features that are not on the same straight line, thereby improving the practicality of the connecting device.
