It spends much larger than the anti-size for misusing 1511 bore of venthole of safety, the anti-partition 156 of misusing of the safety is prevented misusing displacement in safety
When being moved on bar 155, safety can be left completely positioned at the anti-part for misusing septalium 153 of safety and prevents misusing septalium 153.?
In use process, by preventing that misusing feed inlet 157 is packed into a large amount of compressible safe materials, makes to prevent misusing safe sky safely safely
Between generate thrusts in 152 the anti-partitions 156 of misusing of safety pushed to enter that safety is anti-to misuse septalium 153, and guarantee that the thrust is less than
The limiting value for the pulling force that can bear by traction object, at work, input tractive force continue to increase, the peace in compressive traction device
Full substance, the thrust that compressed safe material generates at this time is also increasing, prevents when the thrust in traction device 1 is greater than safety
When misusing thrust caused by the substance in cabinet 151, safety prevents that safety will be pushed away under force by misusing partition 156
Anti- to misuse septalium 153, such Partial security substance runs past the anti-venthole 1511 of misusing of safety and enters in U-type groove 17, rises
To mistake proofing and warning function, the result being damaged caused by excessive by traction object so as to avoid tractive force.
Specifically used mode：In present invention work, in use, mobile trailer wagon is to traction object and by among traction object,
By preventing that misusing feed inlet 157 is packed into a large amount of compressible safe materials, makes to prevent misusing safely in safe space 152 to generate safely
Thrust pushes safety to prevent that misusing partition 156 misuses septalium 153 into safety is anti-, and guarantees that the thrust is less than by traction object institute energy
The limiting value of pulling force is born, fixed link 4 inputted by pulling force respectively and the connection of pulling force output rod 13 draws object and by traction object,
During work, traction object is connected by trailer wagon and by traction object, plays and slows down two articles produced punching in traction
The effect of power keeps the output of tractive force gentler, will not be excessive because of impulse force so that destroying by traction object.Meanwhile inputting traction
Power continues to increase, the safe material in compressive traction device 1, and the thrust that compressed safe material generates at this time is also increasingly
Greatly, when the thrust in traction device 1, which is greater than safety, prevents misusing thrust caused by the substance in cabinet 151, safety is anti-to be misused
Partition 156 will pushed away from safety under force to be prevented misusing septalium 153, and such Partial security substance runs past safety
Anti- venthole 1511 of misusing enters in U-type groove 17, plays mistake proofing and warning function, so as to avoid tractive force it is excessive caused by quilt
Draw the impaired result of object.
It is obvious to a person skilled in the art that invention is not limited to the details of the above exemplary embodiments, Er Qie
In the case where without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
From the point of view of which point, the present embodiments are to be considered as illustrative and not restrictive, and the scope of the present invention is by appended power
Benefit requires rather than above description limits, it is intended that all by what is fallen within the meaning and scope of the equivalent elements of the claims
Variation is included within the present invention.Any reference signs in the claims should not be construed as limiting the involved claims.
