In the figure, the device comprises a base 1, a compression screw 2, a base 3 and a universal rotating mandrel.
Detailed Description
The invention will be further explained with reference to the drawings.
The universal ball core locking mechanism comprises a compression screw 1, a base 2 and a universal rotating mandrel 3; the base 2 is tubular, and the upper end of an inner hole is a contracted cambered surface; the universal rotating mandrel 3 is a cylinder, and the lower end of the universal rotating mandrel is a spherical ball head; the compression screw is arranged on the base and extends into the base 2 along the radial direction, and the front end of the compression screw is a sunken cambered surface; the upper part of a ball head at the lower end of the universal rotating mandrel is contacted with the cambered surface of the inner hole of the base, and the cambered surface at the front end of the compression screw is contacted with the lower part of the ball head.
The upper end of the base 2 is provided with a groove, so that the universal rotating mandrel 3 has a larger rotating range.
The compression screw is provided with a handle.
This application base 2 cavity, the upper end area arc of hole, curved effect is that universal rotatory dabber 2 is packed into from the hole of lower extreme, moves along the axial direction, when the main aspects arc position, because the arc diameter is less than the spherical diameter of universal rotatory dabber 3 to universal rotatory dabber 3 can not pass through the hole smoothly, under the friction of housing screw 1, reaches the purpose of optional position locking.
The universal rotating mandrel 3 is a cylinder with a spherical end part, the spherical diameter of the end part of the cylinder is larger than the arc diameter of the base 2, the friction can be realized, when the cylinder support moves in place as required, the compression screw 1, the base 2 and the universal rotating mandrel 3 are mutually rubbed to achieve the working state
The handle at the tail end of the compression screw 1 is a cuboid with an arc shape, and the handle is of a structure with R and sine lines, so that an operator is not easy to fatigue. The base 2 is a cylinder with steps, so that the base is convenient to fix.
By using the universal ball core locking mechanism, the rotational motion of the compression screw 1 is converted into radial linear feeding motion by clockwise rotating the compression screw, and the radial linear feeding motion and the universal rotating core shaft 3 which performs axial linear motion and rotational motion generate friction, so that the working state of locking at any position is achieved.
And the compression screw 1 is rotated anticlockwise, the rotary motion of the compression screw is converted into radial linear backward motion, friction between the compression screw and the universal rotary mandrel 3 which performs axial linear motion and rotary motion is lost, and the state of unlocking at any position is achieved.
