This creation belongs to the technical field of a folding mechanism, and specifically refers to a folding connection mechanism with high stability, which has the effect of fast operation and labor saving, can effectively prevent any loosening during use, and greatly improves its use. Safety and practicality.

Press, the folding structure is usually the same tube body is designed as a two-section mechanism, and a quick-release connection structure is combined at the separation point to selectively release or fasten the separation point, so that the length of the tube body can be When not in use (such as transportation and storage), it can be reduced in size to facilitate portability or storage. It is commonly used in portable mobility tools such as scooters, bicycles, etc., so that the frame or handlebar riser can be selectively folded and stored with each other. However, most of the existing foldable connecting mechanisms include two connecting pieces pivotally connected on one side of the butt end and used to be respectively fixed with the two monomers to be folded, and two connecting pieces for connecting the two connecting pieces when the two connecting pieces are butted together. The locking elements of the connecting pieces are mutually locked, and the common locking elements are mostly cam-type mechanisms. Both locking and unlocking require manual operation by the user, which is time-consuming and labor-intensive, and brings inconvenience to the user.

Furthermore, this type of folding mechanism has the following drawbacks:

1. In terms of safety, this type of folding mechanism requires a large locking force and requires a large force to operate, which will cause time-consuming and laborious operation, so it is difficult to operate.

2. If it is used in a non-static situation, it is easy to be loose due to vibration between dynamics, which affects the safety of use.

3. The general folding mechanism is fixed in a single way, which cannot prevent it from loosening arbitrarily during use, so when it is improperly loosened, the locking effect will be completely lost, and there are hidden safety concerns during operation.

In other words, the design of the existing foldable connecting mechanism has not yet effectively solved the above-mentioned problems, resulting in troubles in use and safety concerns, and it is necessary to strengthen it. It is also the subject that this creation intends to explore.
