Inner sleeve 2 and be fixedly installed on the union joint 3 of inner sleeve 2 bottom, be provided with between hand pressure trocar sheath 1 and inner sleeve 2 and lead
To rotary components, its driving end 4 can be the telescopic driving end of different size on the market, telescopic driving end match activities
It is fastened on union joint 3.
Wherein, guiding rotary components and include braking guide pin bushing 5, rotary guide sleeve 6 and screw rod 7, described braking guide pin bushing 5 passes through
Being screwed and be set in the top of inner sleeve 2, the inner chamber bottom of braking guide pin bushing 5 is provided with braking ratchet 8, brakes the interior of guide pin bushing 5
Top, chamber is threadably secured and is provided with stopper sleeve pipe 9, and described rotary guide sleeve 6 coupling is slidably located in and brakes ratchet 8 He
In the inner chamber of the braking guide pin bushing between stopper sleeve pipe 9, the bottom of rotary guide sleeve 6 is provided with and brakes what ratchet 8 coupling engaged
Rotary ratchet 10, in the assembling of revoling tube 6 and brake casing 5, brakes guide pin bushing between braking ratchet and stopper sleeve pipe
Cavity length is S, a length of L of rotary guide sleeve, and the height of braking ratchet is H, then S >=L+H such that it is able to guarantee outside hand pressure
During sleeve pipe pull-up, it is possible to ensure that braking ratchet and rotary ratchet efficiently separate.
The spiral internal tooth 11 mating engaged transmission with screw rod 7 it is provided with, on screw rod 7 in the inner chamber of rotary guide sleeve 6
Braking guide pin bushing 5 and rotary guide sleeve 6 are run through in lower two ends；By fastening between upper end and the hand pressure trocar sheath 1 of described screw rod 7
Assembly is fixing to be connected so that screw rod 7 and hand pressure trocar sheath 1 geo-stationary, and can synchronize knee-action, and screw rod 7 is not
Can rotate action, the bottom of screw rod 7 is provided with lower limit assembly, thus departs from system during preventing screw rod pull-up
Dynamic guide pin bushing 5 and rotary guide sleeve 6.
In the present embodiment, preferably fastening assembly is the upper end cover being threadably secured and being arranged on hand pressure trocar sheath 1 upper end
12, described screw rod 7 is threadably secured with upper end cover 12 and is connected；Lower limit assembly includes being arranged on screw rod 7 bottom
Lower limit screw rod 14 and by the fixing spacing shim 13 being pressed on lower limit screw rod 14 of locking nut 15.
The assembling mode of the present embodiment is:
First braking guide pin bushing is fixed on the upper end of inner sleeve, locking nut and lower limit pad are fixedly mounted on screw thread
On the lower limit screw rod of bar, by the top of screw rod through braking guide pin bushing, rotary guide sleeve tooth is coordinated from screw rod with screw rod
Top be inserted in screw rod until rotary guide sleeve be placed on braking guide pin bushing inside, stopper sleeve pipe is fixed on braking guide pin bushing on, draw
Dynamic screw rod, it is ensured that screw rod can do the movement of small distance between stopper sleeve pipe and braking ratchet；Secondly by spiral masthead
The threaded rod in portion is fixed together with upper end cover, is overlapped from bottom to top along inner sleeve by hand pressure trocar sheath and receives on inner sleeve, and hands
Hand pressure trocar sheath is fixed together with end cap on hand by pressure of shaking hands trocar sheath by screw thread；Fix afterwards and connect union joint
And driving end, complete the assembling of automobile-used quick rotary spanner.
The operation principle of the present embodiment is:
In carrying out operating process, automobile-used quick rotary spanner overall package is completed, and makes the driving end of bottom
Corresponding with nuts, ensure that hand pressure trocar sheath and inner sleeve are in extended state simultaneously, both hands hold the upper end of hand pressure trocar sheath,
And press under exerting a force, screw rod coordinates with the spiral internal tooth of rotary guide sleeve, rotates internal tooth transmission moment of torsion, thus guide pin bushing rotation is rotated
Turning, the rotary ratchet of rotary guide sleeve engages each other with the braking ratchet of braking guide pin bushing, thus drives braking guide pin bushing to rotate, and braking is led
Set and inner sleeve are fixedly sleeved structure, therefore inner sleeve, union joint, driving end do spinning movement under the drive of braking guide pin bushing,
Thus coordinated with bolt from driving end, it is achieved the tightening or unscrew of bolt.
During pressure down, owing to rotary guide sleeve can do the upper and lower of small distance between stopper sleeve pipe and braking ratchet
Mobile, instantly during pressure hand pressure trocar sheath, the rotary ratchet of rotary guide sleeve coordinates with the braking ratchet of braking guide pin bushing and is engaged on one
Rise, complete one take turns tighten or unscrew action, hand pressure trocar sheath arrives maximum displacement；When rotary guide sleeve is in bottom, until
When union joint is touched in the bottom of lower limit screw rod, now need to pull up hand pressure trocar sheath, at this during pull-up, the rotation of rotary guide sleeve
Turning the braking ratchet of ratchet and braking guide pin bushing to depart from and coordinates, rotary guide sleeve dallies along screw rod, and rotary guide sleeve and braking plug sleeve
Pipe is fitted；Persistently pulling up, owing to lower limit pad and braking guide pin bushing connect tactile braking, pull-up hand pressure trocar sheath reaches dominant bit
Moving, lower limit pad serves position-limiting action, and prevents screw rod from departing from inside braking guide pin bushing, so far completes an operation and follows
Ring, as bolt length is longer, repeats multiple operation circulation, completes the dismounting of this bolt.
Embodiment two: see Fig. 1-Fig. 6, the structure of the present embodiment is essentially identical with embodiment one, and something in common is the heaviest
Stating, its difference is: when pretightning force is excessive, it is impossible to when being dismounted by hand pressure trocar sheath, by by hand pressure trocar sheath
Carry out entirety with inner sleeve to be fixed as one, utilizing wind big gun to complete dismounting, be wherein provided with on upper end cover 12 and wind big gun transmission
The pneumatic connecting groove 16 connected, is provided with one locked assembly, integrated lock between described hand pressure trocar sheath 1 and inner sleeve 2
Gu assembly includes at least one locking groove 17 being opened in vertically on inner sleeve 2 outer wall, is opened on hand pressure trocar sheath 1
The locking screw rod 19 that the locking screw 18 corresponding with locking groove 17 and coupling are arranged in locking screw, wherein locking screw rod 19
Inner end be protruding hemisphere face structure, the outer end of locking screw rod 19 is provided with tightens otic placode 20.
The operation principle of the present embodiment is:
When, in disassembly process, when required pretightning force is excessive, needing to complete dismounting by wind big gun, it is necessary first to operator tightens
Locking screw rod, locking screw rod passes inwardly through the locking screw at the bottom of hand pressure trocar sheath, and recessed with the locking of the lateral surface of inner sleeve
Groove contacts with each other extruding, thus hand pressure trocar sheath and inner sleeve is connected as a single entity, and quick rotary spanner now is equivalent to one
Individual long sleeve, the driving means of wind big gun coordinates transmission with the pneumatic connecting groove on upper end cover, and the driving force of wind big gun is by being connected
Hand pressure trocar sheath and inner sleeve drive to driving end, drive the rotation of driving end, thus realize tightening or unscrewing of bolt.When
When carrying out back work without wind big gun, operator only need to unclamp locking screw rod so that locking screw rod inner end departs from inner sleeve
The locking groove of lateral surface, until hand pressure trocar sheath can make linear movement back and forth along inner sleeve.
This utility model is not limited to above-mentioned detailed description of the invention, and those skilled in the art also can make multiple change accordingly
Change, but any be equal to this utility model or similar change all should be contained in the range of this utility model claim.
