Specific embodiment
The utility model is described further below in conjunction with Figure of description.
Picture 1-4, fixture shown in Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Figure 10, Figure 11 includes by screw rod 01 with shifting
The first cramping body 02 in grip objects is employed, screw rod 01 realizes its axial movement by screw-driven, as shown, different knots
The fixture of configuration formula realizes that the position of screw-driven is different from screw rod.A torsion-adjustable handle 03 is assembled in the rear end of screw rod 01, leads to
It crosses torsion-adjustable handle and adjusts maximum clamping force, torsion-adjustable handle 03 includes lever 32, first end face tooth with inner cavity 31
33, second end face tooth 34, axial support spring 35, regulating mechanism 06.First end face tooth 33 is located at inner cavity 31, rotationally covers in spiral shell
To transmit torsion on bar 01 and with 32 fixing assembling of lever, specifically, first end face tooth 33 is rotationally covered by cylindrical surface 11
Hex surface is illustrated as on screw rod 01 and by plane 331() cooperate the fixing assembling for realizing itself and lever with lever 32.Second end
Face tooth 34 is located at inner cavity 31 and can engage with skidding with first end face tooth 33, second end face tooth 34 axial movement and with transmitting torsion
It covers on screw rod 01, specifically, 34 sets of the second end face tooth axial directions realized on screw rod 01 and through the cooperation of plane 12 with screw rod
It moves and transmits torsion.Described engage with skidding transmits torsion when referring to second end face tooth and first end face tooth engagement, works as torsion
It skids both when power reaches a certain level, avoids applying gripped object bigger clamping force, for this purpose, as shown in Figure 1, first end
The opposite end face of face tooth 33, second end face tooth 34 is equipped with inclined plane shape tooth, and accordingly, first end face tooth is relative to second end face teeth directional
It when one direction rotation, may be implemented to skid, when this situation is suitable for grip objects, otherwise first end face tooth is relative to second
It when teeth directional another direction in end face rotates, will not skid, this situation is suitable for discharging the object clamped.Axial support spring 5
It is placed between second end face tooth 34 and regulating mechanism 36 for applying elastic force to second end face tooth, which promotes second end face tooth
First end face tooth is contacted, the size of the elastic force determines the acrotorque that screw rod is applied to by lever.Regulating mechanism 36 includes
The rotation of adjusting knob 361, adjusting knob 361 and 32 rolling assembling of lever and adjusting knob is for adjusting axial support spring
Elastic force, therefore the acrotorque for adjusting lever and being applied to screw rod can be realized by rotating adjusting knob.Adjusting knob 361 with hold
32 rolling assembling of handle can be provided separately circular bar, annular groove in the two, enable circular bar card in a ring groove.
The fixture of above structure is held lever 32 and is rotated, then lever 32 is rotated with first end face tooth 33, first end face tooth
Torsion is passed to second end face tooth 34 by 33, and torsion is passed to screw rod 01 by second end face tooth 34, and screw rod 01 is promoted to pass through screw thread
The axial movement of screw rod is realized in transmission, clamps object with the first cramping body 02.When torsion is sufficiently large, which promotes first
The inclined plane shape tooth shaft of second end face tooth 34 to pushing open, is forced second end face tooth to move axially by the inclined plane shape tooth of end-tooth 33, the
One end-tooth and second end face tooth axial separation, which are realized, skids, and cannot apply bigger clamping force again, realizes and precisely clamps, avoids
Torsion crosses macrolesion held object.The maximum clamping force depends on the elastic force of spring, passes through the adjustable bullet of adjusting knob
The elastic force of spring.
In order to it is compact-sized, convenient for assembly, regulating mechanism 36 include swivel nut 362, nut 363.Swivel nut 362 rotationally covers

Cooperate to mobile.Axial support spring 35 is the helical compression spring being sleeved on the screw rod and its both ends is respectively supported at second end
On face tooth 34 and nut 363.
The rear end of screw rod 01 is connected with gasket 364 by screw 366, after swivel nut 362 is limited in screw rod by gasket 364
End.The shaft block ring 38 that restricted screw rod is moved axially relative to lever 32 is covered on screw rod 01.Restricted first is covered on screw rod 01
The shaft block ring 39 that end-tooth 33 is moved axially relative to lever.
Lever 32 is equipped with the window 37 of corresponding nut, and lever is equipped with clamping force scale (not shown), on nut 363
Equipped with index 365, when adjustment spring elastic force, nut axial movement, index and clamping force scale can opposite variation positions
It sets.Therefore when it is implemented, position can be interchanged in index and clamping force scale.In addition, can also be in adjusting knob and lever
On separately be equipped with index, clamping force scale.
