Laws of motion are adjustable.Preferably, the self-lock switch structure can also be on sleeve 4.
Embodiment 2:
The present embodiment is changed in the structure basis that embodiment 1 provides.As shown in Fig. 2, the self-lock switch knot
Structure also includes pushing elastic part 10, and in the released state, fastener 3 is in locked state to pushing elastic part 10.In the present embodiment,
The bead of non-magnet material can be used in fastener 3, and permanent magnetism voussoir 9 no longer has a strong effect bead.Bead is in pushing elastic
Axle construction 2 is locked under the thrust of part 10, rotating handle 7 can push bead open, and axle construction 2 moves freely.Reversely rotate handle 7
When, bead promotes ball under the action of pushing elastic part 10, and axle construction 2 is locked again.Preferably, handle 7 and wedge block 8 it
Between can also be and be slidably connected in the radial direction in axle construction 2, screw hole is provided on handle 7, separately sets a screw rod through screw hole
It is connected afterwards with wedge block 8, wedge block 8 is controlled close to or far from axle construction 2 by rotation screw rod.
Preferably, elastic component 10 can also be will push against and be substituted for pneumatic structure, bead it is separate, close, pass through gas
Blow and inhale realization.Alternatively, will push against elastic component 10 is substituted for hydraulic system, pass through hydraulic drive bead.For pneumatic structure or
Hydraulic system, can be arranged one or two fluid channel on guide part 1, and fluid channel is connected in sliding lock space.For
The structure of one fluid channel, the movement that synchronization is only blown or sucked and (pushed or pulled on)；For the structure of two fluid channels,
Axial direction along guide part 1 is respectively on the both sides of bead, the movement that synchronization can be blown and be inhaled simultaneously and (pushed away and draw), more
Increase effect.Preferably, two fluid channels can be connected to a reversal valve simultaneously, small to control by the movement for controlling reversal valve
The position of ball.
Preferably, the pushing elastic part 10 can also be substituted for energy and cause deformable material, such as memorial alloy, heat expansion be cold
