Fig. 8 A is the top view of the bushing of another embodiment of the application, and Fig. 8 B is the solid of bushing shown in Fig. 8 A
Figure.Embodiment shown in Fig. 8 A and 8B is similar with embodiment shown in Fig. 6 A and 6B, and difference is implementation shown in Fig. 8 A and 8B
Example increases engagement item on the inner wall of liner body.
As shown in figs. 8 a and 8b, bushing 800 includes several interior ribs 808 and several exterior ribs 806, interior ribs
808 and exterior rib 806 be staggered, between two adjacent interior ribs 808 have interval 850.Interior ribs 808 and outer
Portion's rib 806 is axially extending along bushing 800.The cross section of interior ribs 808 is arc-shaped.It is every in interior ribs 808
One is equipped with engagement item 830.It is also arc-shaped for engaging the cross section of item 830, and engages item 830 also along the axis of bushing 800
To extension.Each engagement item 830 extends to an adjacent internal rib from the circular arc starting point 822 of an interior ribs 808
The circular arc starting point 822 of item 808.Due to having interval 850 between two adjacent interior ribs 808, item 830 is engaged from one
The circular arc starting point 822 of interior ribs 808 extends to during the circular arc starting points 822 of an adjacent interior ribs 808 can be across
Thus item 830 and bushing 800 are engaged in the circular arc terminal 824 of more one interior ribs 808 and adjacent interval 850
Deformation space 820 is formed between inner wall 804.And it can see from Fig. 8 A, 830 shapes of engagement item of each interior ribs 808
At deformation space 820 close to the interior ribs 808 position have smaller portions, and close to adjacent spaces 850 position
It sets with major part.
Still as shown in Figure 8 A, in the cross section of bushing 800, the arc-shaped vertex of each engagement item 830 is collectively formed
Circle 812.The diameter of circle 812 and the outer diameter of driving instrument match, so that driving instrument can extend into bushing 800, and can
It is engaged by frictional force with bushing 800.When driving instrument protrudes into rotating bolt 501 in bushing 800, bolt 501, bushing 800
It is be combined with each other, cannot be produced relative rotation due to frictional force with driving instrument three, therefore can by rotate driving tool
So that nut anchorage clip 100 and bolt 501 generate relative rotation.It is worth noting that, in the embodiment shown in Fig. 6 A and 6B,
Driving instrument directly engages the vertex of interior ribs 608, therefore the circle 612 that is collectively formed of the vertex of each interior ribs 608
Diameter and the outer diameter of driving instrument match.However, driving instrument directly engages inside in the embodiment shown in Fig. 8 A and 8B
The vertex engagement of engagement item 830 on rib 808, it is therefore desirable to the circle 812 that is collectively formed of vertex of each engagement item 830 it is straight
Diameter and the outer diameter of driving instrument match.
As an example, bushing 800 is made of elastic material.In this case, engagement item 830 can be pressurized
And it is mobile towards deformation space 820.Therefore, if the diameter for the circle 812 that the arc-shaped vertex of each engagement item 830 is collectively formed
Greater than the outer diameter of driving instrument, then driving instrument can force engagement item 830 to produce when in driving instrument insertion bushing 800
Deformation is given birth to towards the movement of deformation space 820, thereby increases the frictional force between driving instrument and bushing 800.Also, make
In, if the direction of rotation of driving instrument is matched with the structure setting for engaging item 803, bushing can be preferably utilized
800 come increase driving instrument rotation bolt 501 torque.
Specifically, as shown in Figure 8 A, looking down at the top of bushing 800, each interior ribs 808 are from its circular arc starting point
822 extend to its circular arc terminal 824 clockwise.And if looked up from 800 bottom of bushing, each interior ribs
808 extend to its circular arc terminal 824 from its circular arc starting point 822 counterclockwise.As previously mentioned, using bushing 800
When, bushing 800 is installed in bolt 501, and driving instrument protrudes into bushing 800.Since the external wall friction of bushing 800 is bonded on
In bolt 501, and driving instrument frictionally engages in the inner wall of bushing 800, therefore by rotation or rotate driving tool, can be with
Bolt 501 is driven to rotate.For having the bushing embodiment of engagement item 803 shown in Fig. 8 A, the rotation of driving instrument can choose
It is identical from the direction that its circular arc starting point 822 extends to its circular arc terminal 824 as interior ribs 808 to turn direction, preferably to utilize
Bushing 800 come increase driving instrument rotation bolt 501 torque.More specifically, if bushing 800 is mounted in bolt 501
Later, go down in terms of the top of bolt 501, the interior ribs 808 of bushing 800 extend to its circular arc end from its circular arc starting point 822
The extending direction of point 824 is clockwise direction shown in Fig. 8 A, then driving instrument is being inserted into bolt from the top of bolt 501
After in 501, driving instrument rotation bolt can preferably be increased using bushing 800 by being rotated in a clockwise direction driving for tool
501 torque.This is because driving instrument first makes the engagement item 830 at the smaller portions in deformation space 820 when rotated
Deformation is generated, since engagement item 830 is located proximate to interior ribs 808 herein, thus the deformation enables to engagement item 830 to contact
Interior ribs 808, the rotary force so as to apply driving instrument pass to interior ribs 808, and thereby pass to along rotation
Next adjacent exterior rib 806 in direction.As a result, the rotary force that driving instrument applies can increase exterior rib
Frictional force between 806 and screw rod 501.In addition, generating the engagement item 830 at the smaller portions in deformation space 820 first
The reaction force increase engagement item for the interior ribs 808 that deformation is subject to when also can contact interior ribs 808 by engagement item 830
Frictional force between 830 and driving instrument.Frictional force between said external rib 806 and screw rod 501 and engage item 830
The increase of frictional force between driving instrument is conducive to the torque of driving instrument rotation bolt 501, so that operator
Member can rotate bolt 501 more labor-savingly to the length of adjusting nut anchorage clip.
Bushing manufacture craft in the application is simple, easy to form.
