The inner diameter of the ring 4 is larger than the inner diameter of the circumscribed circle of the nut body 3, the outer diameter of the lock ring 4 is smaller than the inner diameter of the lock 1, the lock plate 2 is an arc-shaped metal plate, and the number of the lock plates 2 is greater than or equal to three. One end of the short side is connected to the nut body 3, the other end of the lock plate 2 is connected to the lock pawl 5, the lock plate 2 is inclined to the outside of the nut body 3, and the lock buckle 1 is provided at the connection end of the lock pawl 5 and the lock plate 2. The outer side of the lock buckle 1 is a concave arc.
In the process of driving the car, it is inevitable to use the brake frequently, which will cause the gap between the brake drum and the friction pad of the car to become larger. Therefore, it needs to be adjusted in time, otherwise, the hidden danger of unsafe driving will be buried due to the excessive braking distance and the out-of-round brake drum. Therefore, motor vehicles must be equipped with automatic adjustment arms. In the existing automatic adjustment arm, the worm inside the housing is limited by the spring pad, the spring and the spring cover, and the end face of the spring pad is directly in contact with the worm, and the rotation of the worm is inflexible due to frictional resistance during rotation.
M4 grounding screw used to fix the grounding wire on household appliances and other equipment, the stud is cylindrical, and the thread is perpendicular to the end (section) surface. However, the screw holes on the equipment all have tapping guide grooves for sinking and guiding due to the manufacturing process requirements. When fixing the ground wire, if the screw is not positioned accurately (the screw is inclined), the screw is pressed down hard, which is easy to cause the screw and the screw. The screw hole bites the teeth, and after biting the teeth, it is easy to cause the screw to loosen or fall off, posing a safety hazard.
When the iron pot is manufactured, the iron head is connected to the iron pot body through rivets, and then the pot handle is set through the iron head, and the iron head connects the pot handle and the iron pot body together. However, when the iron head is installed, the position may be inaccurate. At this time, it is necessary to remove the rivet and reinstall the iron head. At present, the removal of rivets is completely done manually, that is, workers use screwdrivers to unscrew the rivets, which is difficult to remove, wastes a lot of manpower, and has low work efficiency, thereby reducing production efficiency.
By adopting the above technical solution, the setting of the pin cap allows the user to conveniently drive the pin into the pin hole of the workpiece by using a hammer and other power-assisted equipment. Pin hole, the plane of the top contact body relative to the pin cap will collide with the plane where the pin hole is located, the convex body and the pin hole are tightly squeezed, and the pin cannot fall off.
