The conditions such as 802 radian, length, width can control transmission arm 8 to the gradual change pressing force of sliding block 7, and then meet different product and want
It asks；When hinge arms 6 open and close, limiting slot 802 and guide pin 9 interact, so that transmission arm 8 is movable by intended trajectory, and make
With the pressing of sliding block 7 in fixing seat 5, transmission arm 8 changes the pressing active force of sliding block 7 with open/close states, and then effectively controls
The size of frictional force between sliding block 7 and fixing seat 5, and then control hinge arms 6 closure or any hovering automatically.
Further, elastic parts includes elastic component 2 and drive rod 1,2 one end elastic reaction of elastic component on drive rod 1,
Other end elastic reaction makes the sliding of 1 elastic reset of drive rod in fixing seat 5, transmission arm 8 and 1 phase of drive rod in fixing seat 5
It connects, so that drive rod 1 is acted on 8 elastic reset of transmission arm, i.e., the elastic reaction of elastic component 2 is on transmission arm 8.
Further, elastic component 2 is helical spring, and 1 one end of drive rod is equipped with position-limited wing 101, the other end is equipped with connecting hole
102, drive rod 1 is inserted in 2 inside of elastic component, and 2 one end elastic reaction of elastic component is on position-limited wing 101, other end elastic reaction
In fixing seat 5,1 other end of drive rod is through elastic component 2 and passes through 801 hook of connecting hook on connecting hole 102 and transmission arm 8
It connects.Elastic parts further includes attachment base 4, and elastic component 2 passes through 4 elastic reaction of attachment base in fixing seat 5,1 one end of drive rod
It is connect through attachment base 4 and protruding into fixing seat 5 with transmission arm 8；Rotation stop pin 3 is provided on drive rod 1, which is stuck in
On attachment base 4, drive rod 1 is effectively prevent to rotate.
Further, axle sleeve 10 is provided in fixing seat 5, guide pin 9 is plugged on axle sleeve 10, and fixed by axle sleeve 10
In fixing seat 5,9 relative rolling of guide pin effectively reduces limiting slot 802 and guiding in limiting slot 802 for position rotation
Frictional force between pin 9 keeps the switching motion of hinge arms 6 more smooth.
