It is moved perpendicular to X-direction on 6 edge of wheel.Tongue 3 is pressed to be equipped with a pair of of lug 33 backwards to the end two sides of guide surface 31, which is used for
It is connect with second back-moving spring 44.
Driving portion 4 includes pedestal 41, button 42, first back-moving spring 43, second back-moving spring 44, upper ratchet 5, lower part
Ratchet 6.Pedestal 41 has the square groove 411 for accommodating pressure tongue 3 and the circular hole for accommodating upper ratchet 5 and lower ratchet 6
412,412 inner wall of circular hole is fixed with the sliding rail 413 of three equal parts, and sliding rail 413 is used for for about 5 play of upper ratchet and under controlling
Portion's ratchet 6 rotates.412 inner wall of circular hole, which is located above sliding rail 413, is equipped with first back-moving spring 43, and first back-moving spring 43 is for multiple
Position upper ratchet 5, makes upper ratchet 5 have the power on X axis always.412 top of circular hole, which has, prevents upper ratchet 5 from popping up
Stop collar 414.A pair of of second back-moving spring 44 is equipped in square groove 411, second back-moving spring 44 is connect with lug 33, and second is multiple
Position spring 44 for resetting pressure tongue 3 makes that tongue 3 is pressed to have the power towards square groove 411 always.Square groove 411 and circular hole 412 mutually hang down
Directly.
Button 42 is located at 5 upper end of upper ratchet, and part button 42 is contained in circular hole 412, and button 42 is for driving driving
Portion 4.42 end of button has the limiting section 421 for preventing button 42 from popping up.
For the tool of upper ratchet 5 there are three the top tooth angle 51 of equal part, the tooth tip B of top tooth angle 51 is downward.Top tooth angle 51
It is on one side the right-angle side 7 for being parallel to sliding rail 413, the another side of top tooth angle 51 is the bevel edge that certain angle is kept with right-angle side 7
8.There is the top sliding slot 52 slided with cooperation sliding rail 413 close to the side of right-angle side 7.Upper ratchet 5 moves down along sliding rail 413
It is dynamic.
Lower ratchet 6 has tooth corresponding with top tooth angle 51 to 61, and tooth includes a pair of of lower part tooth angle 63, lower teeth to 61
The tooth tip B at angle 63 is upward.Lower part tooth angle 63 is identical as 51 angle of top tooth angle.It is right with sliding rail 413 to have between lower part tooth angle 63
The angle 9 answered, tooth is to 61 and adjacent tooth to having the lower part sliding slot 62 slided with cooperation sliding rail 413, lower ratchet 6 between 61
It is rotated clockwise or counterclockwise along X-axis.The bottom of lower ratchet 6 is additionally provided with conus portion 8, and conus portion 8 and the circular platform type of pressure tongue 3 lack
32 mutual extrusions of mouth.
Button 42, upper ratchet 5, lower ratchet 6, pressure tongue 3 are located inside circular hole 412 and along X-axis successively phases from top to bottom
It connects.Pedestal 41, button 42, upper ratchet 5, lower ratchet 6 and pressure tongue 3 are made of plastics.
The lock screw machine clamp first has to for components A to be tightened being placed on pedestal 1, prevent at this time during clamping
The pressure tongue 3 of chaser structure 2 is in evacuation position, facilitates the placement of components A to be tightened.Then push button 42, at this time in circular hole 412
Sliding rail 413 on wall is located at top sliding slot 52, in lower part sliding slot 62.During the decline, the tooth tip B of top tooth angle 51
It offsets with the tooth tip B of lower part tooth angle 63, lower part tooth angle 63 declines along sliding rail 413 under force, sliding dropping to lower part
When slot 62 is detached from sliding rail 413 completely, since top tooth angle 51, lower part tooth angle 63 have the inclined-plane 71 being parallel to each other, lower teeth
Angle 63 occurs clockwise or counterclockwise therewith.Right angle of the rotation of lower part tooth angle 63 extremely with top tooth angle 51, lower part tooth angle 63
When the position that side 7 is bonded to each other, the lower end of sliding rail 413 resists the angle 9 between lower part tooth angle 63, presses tongue 3 in conus portion 8
Extruding under by avoid position be moved to anti-jump position.During squeezing pressure tongue 3, the clockwise or inverse time occurs for conus portion 8
The rotation of needle.Since conus portion 8 is up big and down small shape, when the circular platform type notch 32 with pressure tongue 3 contacts, conus portion 8 is along X
Axis, which moves down, makes to press tongue 3 to be changed into perpendicular to X-direction movement.Effect of the last upper ratchet 5 in first back-moving spring 43
Under be reset to initial position, sliding rail 413 is bonded with the right-angle side 7 of lower ratchet 6.
The lock screw machine clamp only needs push button 42 during release, and the top of sliding rail 413 is located at top at this time
In sliding slot 52, the lower end of sliding rail 413 resists the angle 9 of lower ratchet 6.During the decline, the tooth of top tooth angle 51
The tooth tip B of sharp B and lower part tooth angle 63 offset, and lower part tooth angle 63 declines along sliding rail 413 under force, are dropping to lower part
When sliding slot 62 is detached from sliding rail 413 completely, since top tooth angle 51, lower part tooth angle 63 have the inclined-plane 71 being parallel to each other, lower part
Tooth angle 63 occurs clockwise or counterclockwise therewith.Lower part tooth angle 63 rotation to top tooth angle 51, lower part tooth angle 63 it is straight
When the position that the arm of angle 7 is bonded to each other, sliding rail 413 is simultaneously in the end close to lower part sliding slot 62, but at this time for the lower end of sliding rail 413
It is not contained in lower part sliding slot 62.Subsequent upper ratchet 5 is reset to initial position under the action of first back-moving spring 43, on
Portion's ratchet 5 occurs slightly to rotate with lower ratchet 6, make lower ratchet 6 moved up immediately under the action of second back-moving spring 44 with
It is contained in sliding rail 413 in lower part sliding slot 62.Finally pressure tongue 3 is moved to evacuation position from anti-jump position.
Refer to Fig. 6, in the second embodiment of the utility model, driving portion 4 is pneumatic cylinder, driving portion 4 include cylinder C 1,
Piston rod C2.Cylinder C 1 is made of steel, and the end of piston rod C2 is equipped with screw rod E, and screw rod E has external screw thread, presses the end of tongue 3
With internal screw thread, screw rod E is threadedly coupled with pressure tongue 3.Pressure tongue 3 is cylindrical type, and pressure 3 end of tongue has to be contacted with components A to be tightened
Guide surface 31, guide surface 31 is the inclined-plane upwardly extended towards in the middle part of components A to be tightened or cambered surface.Piston rod C2 passes through cylinder C 1
It moves reciprocatingly, to make that tongue 3 is pressed to move between anti-jump position and evacuation position.
Refer to Fig. 7, in the 3rd embodiment of the utility model, driving portion 4 is motor, and driving portion 4 includes stator D1, turns
Axis D2.Pressure tongue 3 has the plate-like contact portion 3A contacted with components A to be tightened.The end of rotating shaft D 2 is equipped with screw rod E, and screw rod E has
External screw thread, the side of pressure tongue 3 have internal screw thread, and screw rod E is threadedly coupled with pressure tongue 3.2 rotation direction of rotating shaft D and pressure 3 side of rotation of tongue
To consistent.Rotating shaft D 2 makes that tongue 3 is pressed to rotate between anti-jump position and evacuation position by rotation.
The lock screw machine clamp can be realized by push button 42 presses tongue 3 to move between anti-jump position and evacuation position,
The lock screw machine clamp structure is simple, good clamping effect.
Obviously, it is practical without departing from this can to carry out various modification and variations to the utility model by those skilled in the art
