Embodiment
With reference to specific implementation example, technical solution of the present invention is further illustrated.
Such as accompanying drawing 1-5 shows, designs a kind of allosteric type module leading screw self-locking plane connecting equipment, and the attachment means include circle
Disk 1, snatch interface 2, motor firm banking 3, bearing base 4 and bearing gland 7, leading screw 5, the nut slider 6 coordinated with leading screw,
The slide rail 8 for supporting sliding block 6 to move, the bar 9 being connected with sliding block 6, snatch interface handgrip 10, handgrip rotates fixing axle 11, with leading screw
Synchronous gear 12 is rotated, while the gear 13 coordinated with gear 12 and motor 14.
Wherein, four identical snatch interfaces 2 are uniformly distributed in the connection circumference of plane disc 1, i.e., adjacent snatch interface
It is 90 ° to be separated by angle.Four identical snatch interfaces 2, two of which is in relative position (being separated by 180 ° of angle)
Interface be used as snatch interface, two other interface, then for installing handgrip 10.The handgrip 10 rotates fixing axle by handgrip
11 fix, and handgrip only has rotational freedom.Symmetrical two leading screws in both sides for installing handgrip 10, two leading screw one are
Right-handed thread, one are left hand thread (leading screw meets the condition of self-locking of revesal), with symmetrical bearing base 4 and bearing
Gland 7, which coordinates, to be installed, and the axle of two leading screws is completely superposed.A nut slider coordinated with leading screw is cased with two leading screws respectively
6, the size of two nut sliders is identical with feature.The slide rail 8 that sliding block 6 is moved is supported to be symmetrically fixed on connection plane disc
On 1；The bar 9 being connected with sliding block 6 coordinates with the chute on handgrip 10 to be installed.The gear 13 is engaged with gear 12, and with institute
Fixation is installed in the rotating shaft for stating motor 14；The end of motor is fixed by motor firm banking 3, and the motor firm banking 3 fixes peace
