Specific embodiment
As shown in Figure 1, Figure 2, the locking pliers appearance and structure of general type, the fixation jaw claw including fixed handle 10 He its end
11, movable jaw claw 16 and can fixed handle 15 can be pivoted relative to fixed handle 10, to open and close jaw claw；Operate locking pliers
When, can fixed handle 15 be closed relative to fixed hand tenon 10, to be closed two jaw claws and firmly grip workpiece between them.
Locking and relieving mechanism 20 are set to the tail end of fixed handle 10, which includes a release lever 28 with pivoting point
281 are connected to fixed handle 10.The lock state and unlocked state of the mechanism 20 control locking pliers.
Such as Fig. 3 to Fig. 6, which includes a fixes sleeve 21, which, which has, is opposite in the fixation jaw claw
A 11 jaw claw end 211 and the tail end 212 for being opposite in 10 tail of the fixed handle end；The center of the fixes sleeve 21 wears one
The locking level 22 being reciprocally moveable.The inner wall surrounding of the fixes sleeve 21 locking level 22 sets several keyways 23, and keyway 23 has
Cell wall 231 is tilted, which is from the jaw claw end 211 of the fixes sleeve 21 to 212 squint of tail end.
Sliding in each keyway 23 to set a key teeth 24, key teeth 24 includes that 241 sliding sleeve of sliding part in the keyway 23 and contacts
Cell wall 231 is tilted, key teeth 24 further includes the flank of tooth 242 for being opposite in the locking level 22.It is set inside the jaw claw end 211 of fixes sleeve 21
One spring 25 and a pushing block 26,26 ejection of the pushing block key teeth 24 are held in contrast；It is sliding that the tail end 212 of fixes sleeve 21 sets one
Lantern ring 27,27 ejection of the sliding sleeve ring key teeth 24 are held in contrast.
The release lever 28 presses end 282 and a promote-side 283 including one, presses end 282 and protrudes out the fixed handle 10, pushes away
Moved end 283 is protruded into fixed handle 10 and pushes away touching sliding sleeve ring 27.
The locking level 22 stretch through out the 21 jaw claw end 211 of fixes sleeve rod end connection one be set to the fixed handle 10 in
Connecting rod 31, the connecting rod 31 are connected to a bias spring 32 being set in the fixed handle 10, and locking level 22 is opposite in fixed jaw
End also contact the first rod end 331 of an intermediate bar 33, the second rod end 332 of the intermediate bar 33 can by a pivoting point 333
Being connected to for rotation can fixed handle 15.First rod end 331 of intermediate bar 33 is also connected to the connecting rod 31 via a connection piece 34
With the bias spring 32.
Such as Fig. 1 to Fig. 5, when by locking pliers locking folder clamping of workpieces, release lever 28, the promotion of the release lever 28 should be first pushed
End 283, which pushes away, touches the sliding sleeve ring 27, which pushes the key teeth 24, and several key teeths 24 are mobile toward the direction of compressed spring 25,
And so that the flank of tooth 242 is left locking level 22 because of the guiding of inclination cell wall 231, locking level 22 is made to have shifting in fixes sleeve 21
Dynamic freedom, can fixed handle 15 can be relative to the activity of fixed handle 10；Then can fixed handle 15 relative to fixed handle 10
Closure to be closed fixed jaw claw 11 and movable jaw claw 16, can fixed handle 15 it is mobile when affect the intermediate bar 33, the of intermediate bar 33
One end is mobile toward the direction for compressing the bias spring 32, which pulls the locking level 22 mobile simultaneously.When locking pliers clamp
After workpiece, the release lever 28 is decontroled, the elastic force of the spring 25 acts on the key teeth 24, makes because of the guiding of inclination cell wall 231
The locking level 22 is bitten in the engagement of the flank of tooth 242, to brake the locking level 22, locking pliers are maintained to the locking shape for clamping workpiece
State, user do not need to apply again continuous power in can fixed handle 15.
Conversely, locking pliers are discharged from lock state, need to press the release lever 28 presses end 282, with its promote-side
283 push away the touching sliding sleeve ring 27, which pushes the key teeth 24, and several key teeths 24 are mobile toward the direction of compressed spring 25, and
And so that the flank of tooth 242 is left locking level 22 because of the guiding of inclination cell wall 231, so that locking level 22 is had movement in fixes sleeve 21
Freedom；At this point, bias spring 32 releases energy, the connector 34, the connecting rod 31 and the locking level 22 are pushed, and make intermediate bar
33 is mobile, can fixed handle 15 toward fixed handle 10 is pushed away, fixed jaw claw 11 and movable jaw claw 16, which are opened, unclamps workpiece, locking pliers
In unlocked state.
Locking pliers decontrol the release lever 28 when being in unlocked state, as previously mentioned, the flank of tooth 242 of the key teeth 24 can be engaged again and be stung
The firmly locking level 22, so that locking pliers are maintained at unlocked state, such benefit be open can fixed handle 15 will not shake.
Such as Fig. 7, Fig. 8, locking level 22 is equipped with a lock segments 221 and the flank of tooth 242 of key teeth 24 cooperates, and stings each other so as to increasing
The stability of conjunction makes locking level 22 when being locked by key teeth 24 entirely without the anxiety of slippage.The lock segments 221 can be thread segment or pressure
Flower face.
The above descriptions are merely preferred embodiments of the present invention, not makees in any form to the utility model
Limitation, it is made by the above technical examples according to the technical essence of the present invention it is any it is simple modification, equivalent variations with
Modification, is still within the scope of the technical solutions of the present invention.
