It is quick to open, solve the contradiction between the pretightning force of closing and the quick opening of block.
Should illustrate it is following some：
The 1st, although the first force component utilizes the magneticaction of two magnet rings, the first force group with guide's force component
In part between the first magnet ring 31 and the second magnet ring 32 when relatively rotating, both axial parts are not moved, so that
Moment of torsion required for first magnet ring 31 and the second magnet ring 32 relatively rotate is larger, and the 3rd magnet ring 61 that guide exerts a force in component with
Between 4th magnet ring 62 when relatively rotating, both meetings are axially moved, and both are axially moved such that both are relative and turned
It is smaller to move desired torsion.In this way, first guide plate 50 is because the exert a force above-mentioned reason of component of guide is easier to open, and baffle plate 20 is because of the
The above-mentioned reason of one force component is not easy to open.Above-mentioned first force component exerts a force component to the closing main body of baffle plate 20 with guide
10 and first guide plate 50 it is easily upon opening be very favorable.
2nd, the 3rd magnet ring 61 causes the first magnet 41 to move while being rotated relative to the 4th magnet ring 62 so that the first magnet
41 move in its longitudinal direction required for power it is smaller, that is to say, that the power will not cause first guide plate 50 to open difficulty, though and
So using less power and enable to the first magnet 41 relative with the second magnet homopolarity, and now the first magnet 41 and the second magnetic
Magnetic repulsion caused by body is but very big, can push against baffle plate 20 and open at once.
To make the first magnet 41 and the second magnet and the 3rd magnet ring 61 in the second force component and guide's force component
And the 4th not mutual magnetic force interference between magnet ring 62, it is made up as shown in figure 3, being provided with the first magnet 41 of non-magnet_conductible material
