The existing way to achieve radial locking of the shaft is generally to sleeve the positioning block on the shaft, and then use a cylindrical pin to pass through the positioning block to lock the shaft. The locking structure and method are as follows: A locking groove with an arc-shaped cross-section is set on the outer side of the shaft along the direction perpendicular to the axis of the shaft, an opening is set on the positioning block, and then a cylindrical pin is used to pass through the positioning block from the outside of the positioning block and screw the lock at one end of the cylindrical pin. When the lock nut is tightened, the opening on the positioning block will be deformed inwardly and locked on the shaft.

Rivets are usually used for riveting the connection between objects, and usually require the use of specific special tools to operate. There are many types of rivets, such as round head rivets, flat cone head rivets, countersunk head rivets, half countersunk head rivets, flat head rivets, hollow rivets, tubular rivets, sign rivets, etc. in order to meet different operational needs.


On the other hand, when assembling many pin installation mechanisms, one end of the pin needs to be installed into the hole or arranged in the hole, and then the other end of the pin is applied to the pin through the pin installation mechanism, so that the pin is fixed in the hole. In the hole of the hole type product. This fixing method is not only extremely inefficient. And it is not possible to install multiple pins at once. Especially when exemplified at the other end of the pin, since there is nothing to hold the pin stable when the pin enters the hole type product, when force is applied to the other end of the pin, the pin can easily bend and damage the pin. .
