Further, it would be desirable to lateral elongated slot 22 is set in handle side, lateral elongated slot extend axially forward until
Penetrate the front end face of handle.Back segment screens of the socket bar away from sleeve is in lateral elongated slot, and lateral elongated slot is away from handle front end one
Rotary shaft 23 is set between two relative sides of side, rotary shaft be located at socket bar radially, so that perpendicular to socket bar,
The rear end of socket bar is rotatablely connected by rotary shaft and handle.
When socket bar screens is in lateral elongated slot, the part that socket bar exposes outside handle is shorter, at socket bar now
In standard state, sleeve spiral shell batch can be used to that outer-hexagonal head is exposed or outer-hexagonal bolts in shallower counterbore are torn open
Dress, and the length of whole sleeve spiral shell batch is shorter, therefore it is convenient for carrying use.When we need dismounting to be located at compared with outer in running-deep-hole
During hex screw, socket bar can be turned out 90 degree at lateral elongated slot, make socket bar and the substantially perpendicular T-shaped of handle.
That is, socket bar now is largely exposed to be in lengthening state outside handle, so as to for positioned at compared with running-deep-hole

Axle position separates in regulation elongated slot away from sleeve side, sleeve rod rear end now with the first positioning hole, and therefore, we can be easily
Socket bar is rotated 90 degree, then, then compress the sleeve of socket bar front end, make the rear end grafting of socket bar and be positioned at handle
In second positioning hole, rotary shaft now is positioned at regulation elongated slot close to sleeve side.That is, the present invention is by socket bar
Rear end sets a regulation elongated slot, can both make socket bar can reliable location under two states, it is ensured that socket bar and handle it
Between can be connected to one, while socket bar is carried out 90 degree of back rotation again.
We can also set the reinforcing through hole 26 for radially penetrating side in the rear end of handle.So, when we are dismounting
During exposed outer-hexagonal bolts, a boosting-rod can be also inserted in the reinforcing through hole of handle rear end, boosting-rod forms T with handle
Font, so as to increase moment of torsion during dismounting outer-hexagonal bolts, be advantageous to some because the reasons such as corrosion are difficult to the outer-hexagonal spiral shell dismantled
The dismounting of nail.
It is understood that radius and set can be made by the bottom surface of lateral elongated slot and close to the side of handle rear end in we
The semi-cylindrical of the radius adaptation of cylinder bar.So, can be with lateral elongated slot when socket bar is located at standard state and lengthens state
Bottom surface and trailing flank good fit, so as to increase the support to socket bar, improve stability of the socket bar under two states.
In order to limit peak torque during sleeve spiral shell batch work, as shown in Figure 3, Figure 4, we can connect in sleeve and socket bar

V-shaped due to brake pad close to the side of socket bar in indent, so as to form two inclined inclined-planes, Jin Er
The small space in both sides broad in the middle is formed between brake pad and socket bar.Positioning stage clip makes brake pad extruding rolling by two damping blocks
Pin.When our rapidly turning set cylinder bars, needle roller is driven to be sidewindered to the one of space by the frictional force of the periphery of socket bar
It is dynamic so that needle roller is formed self-locking by the extruding of brake pad and socket bar, so as to socket bar and needle roller and needle roller with
Enough frictional force is produced between brake pad, now, socket bar can rotate to dismount outer-hexagonal bolts together with moving sleeve.When
When the moment of torsion that we are applied on sleeve spiral shell batch is excessive, needle roller can promote brake pad and two damping blocks overcome and determine square stage clip
Elastic force be displaced outwardly so that produce skidding between socket bar and sleeve, can be effectively prevented from because the moment of torsion of application is excessive and
Cause the damage of sleeve or outer-hexagonal bolts.Due to being to be bonded inclined-plane and friction by inclined between damping block and brake pad
What inclined-plane sticked together, therefore, brake pad can make damping block be close to the side of rectangular through slot to the active force of damping block, so as to
Frictional force is produced between damping block and rectangular through slot, so as to significantly decrease the requirement of the elastic force to determining square stage clip, favorably
In reducing brake pad, damping block and the size for determining square stage clip, make overall structure more compact, while ensure that sleeve spiral shell batch can produce
Raw enough moments of torsion.

Because the rotating disc for being connected to sleeve boom end can rotate in the spherical hollow space in sleeve, therefore, when we meet
When shelter be present above to the outer-hexagonal bolts for needing to dismount, socket bar relative sleeve can be rotated an angle by us
Degree, then sleeve is socketed on the outer-hexagonal bolts for needing to dismount, so that socket bar avoids the shelter of top.Due to this
When socket bar velocity of rotation it is slower, therefore, ball now will not form self-locking because of extruding.Then, we can be rapidly
Turning set cylinder bar, so as to drive a side roll of the ball to space by the frictional force of the sphere on the outside of rotating disc, ball by
The extruding of brake pad and rotating disc and form self-locking, it is enough so as to be produced between rotating disc and ball and ball and brake pad
Frictional force, now, socket bar can by rotating disc band moving sleeve rotate together to dismount outer-hexagonal bolts.
