Fig. 1-3 is please referred to, the utility model provides a kind of technical solution: one kind can reduce the dipentodon sinicus key of the degree of wear Axis, including main body 1, card slot 2, covering 3, shaft 4, fixation hole 5, outer groove item 6, limit plate 7, loop bar 8, interior groove item 9, reset Spring 10, buckle 11, fixed ring 12, external splines 13, spline tooth 14 and anti-abrading block 15, the top of main body 1 are equipped with card slot 2, and The left side of card slot 2 is mounted with covering 3, and the two sides up and down for covering 3 are equipped with shaft 4, and fixation hole 5 is applied in the left and right two of main body 1 Side covers 3 and constitutes rotational structure by shaft 4 and card slot 2, and is vertical structure between fixation hole 5 and card slot 2, by main body 1 It connecting between top and corresponding part, part applies pressure to covering 3 and opens covering 3 under the action of shaft 4 at this time, And then by cruciate flower alligator with needing the part connected to combine, covering 3 can prevent preliminary placement is carried out inside card slot 2 Dust siltation is stopped in card slot 2, reduce loosening of the device when in use between crossing spline and other parts can Can, the service life of cruciate flower alligator is improved, the outside of main body 1 is fixed with outer groove item 6, and the bottom of main body 1 is mounted with Limit plate 7, the outside of main body 1 is equipped with loop bar 8, and the inside of loop bar 8 is mounted with interior groove item 9, outer groove item 6 and main body 1 Between be bonding connection, while between loop bar 8 and interior groove item 9 be bonding connection, and the insection structure of outer groove item 6 with it is interior The insection structure of groove item 9 matches, and turn main body 1 clockwise passes through the groove phase between outer groove item 6 and interior groove item 9 Mutually occlusion rotation, main body 1 is screwed out from loop bar 8, and then cruciate flower key length is increased, it is big to some intervals into Row adapts to, and turn main body 1 counterclockwise is mutually twisted rotation by the groove between outer groove item 6 and interior groove item 9, by main body 1 It screws in loop bar 8, and then cruciate flower key length is reduced, it is small to some intervals to adapt to, pass through main body 1 and set Stretching between bar 8 can adapt to different spaces size, it is therefore prevented that crossing spline is too long or too short and leads to its nothing Method uses, and improves the ability that crossing spline adapts to different situations, improves the use scope of crossing spline, loop bar 8 and main body 1 Between to be flexibly connected, and loop bar 8 constitutes fixed structure by limit plate 7 and main body 1, and limit plate 7 can prevent the mistake of main body 1 The rotation of degree, it is therefore prevented that main body 1 falls off, it is therefore prevented that crossing spline falls off and cause the damage of device when running Bad, fixation hole 5 can prevent from causing to rotate between main body 1 and loop bar 8 because of the rotation of device operation, improve for device Stability, reset spring 10 is mounted on the bottom of loop bar 8, and the top of reset spring 10 is connected with buckle 11, loop bar 8 passes through Buckle 11 is snap-in structure with fixed ring 12, and buckles 11 and constitute elastic construction by reset spring 10 and fixed ring 12, downwards Buckle 11 is pressed, drives reset spring 10 to shrink, and then loop bar 8 and fixed ring 12 can be dismantled, unclamps buckle 11, Under the elastic reaction of reset spring 10 itself, buckle 11 is fixed with fixed ring 12, and then by loop bar 8 and can consolidated Determine ring 12 to be dismantled, be applied in combination by reset spring 10 and buckle 11, loop bar 8 and fixed ring 12 can be carried out quickly Dismounting and change, reduce between the two because some damage parts makes replacement cost, saved for device maintenance corresponding Cost reduces unnecessary waste, when in use reset spring 10 and buckle 11 can also be improved loop bar 8 and fixed ring 12 it Between fastness, the bottom of loop bar 8 is equipped with fixed ring 12, and the bottom of fixed ring 12 is fixed with external splines 13, external splines 13 Be fixedly arranged above spline tooth 14, and the positioned inside of spline tooth 14 has anti-abrading block 15, and the shape of spline tooth 14 is alphabetical " T " Shape, and to be welded to connect between spline tooth 14 and anti-abrading block 15, the spline tooth 14 of " T " shape can prevent itself and other parts from existing It skids when use, causes the using effect of device bad, anti-abrading block 15 can reduce spline tooth 14 and other parts Between too strong confrontation and cause the fracture of spline tooth 14, improve the service life of spline tooth 14, reduce spline tooth 14 Abrasion.

Working principle: for this kind of dipentodon sinicus key axis, first by connecting between the top and corresponding part of main body 1 It connects, part applies pressure to covering 3 and opens covering 3 under the action of shaft 4 at this time, and then by cruciate flower alligator and needs The part of connection combines, and covering 3 can be to carrying out preliminary placement inside card slot 2, it is therefore prevented that and dust deposits in card slot 2, The possibility for reducing loosening of the device when in use between crossing spline and other parts improves making for cruciate flower alligator Then fixed link is fixed by fixation hole 5 with other parts with the service life, master is then rotated according to actual requirement Body 1, turn main body 1 clockwise are mutually twisted rotation by the groove between outer groove item 6 and interior groove item 9, by main body 1 from It is screwed out in loop bar 8, and then cruciate flower key length is increased, big to some intervals to adapt to, turn master counterclockwise Body 1 is mutually twisted rotation by the groove between outer groove item 6 and interior groove item 9, and main body 1 is screwed in loop bar 8, and then will Cruciate flower key length is reduced, small to some intervals to adapt to, while limit plate 7 can prevent the excessive of main body 1 Rotation, it is therefore prevented that main body 1 falls off, it is therefore prevented that crossing spline falls off and causes the damage of device when running, Fixation hole 5 can prevent from causing to rotate between main body 1 and loop bar 8 because of the rotation of device operation, improve for device The spline tooth 14 of stability, last " T " shape can prevent it from skidding when in use with other parts, cause device Using effect is bad, and anti-abrading block 15 can reduce too strong confrontation between spline tooth 14 and other parts and cause spline tooth 14 Fracture, improves the service life of spline tooth 14, entire dipentodon sinicus key axis is completed in the abrasion for reducing spline tooth 14 like this Use process.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
