On end face and the two is connected to, and as a kind of specific implementation mode of the present embodiment, it is pipe to limit above-mentioned stress conduit 4,
Outer diameter is less than the outer diameter of above-mentioned internal thread axle sleeve 3, and limits above-mentioned internal thread axle sleeve 3 and the internal diameter of above-mentioned stress conduit 4 is big
It causes identical.Above-mentioned threaded rod 1 is screwed onto in the threaded hole of internal thread axle sleeve 3, at this point, when rotating threaded rod 1, above-mentioned spiral shell
Rasp bar 1 can move up and down in the endoporus of above-mentioned stress conduit 4.
In the present embodiment, as shown in Figures 2 and 3, through-hole radially is offered on the tube wall of above-mentioned stress conduit 4
41, one end that above-mentioned stress is applied to block 2 passes through the through-hole 41 and stretches into stress conduit 4, limits the stress and applies the sliding of block 2
In the through-hole 41, it can be moved freely along the through-hole 41 so that the stress applies block 2.
In the present embodiment, as shown in Figures 2 and 3, limits above-mentioned threaded rod 1 and stretch into internal thread axle sleeve 3 and stress conduit 4
Interior one end is up big and down small conical head 11, and when use, the cone end of above-mentioned conical head 11 is stretched into stress conduit 4 simultaneously
And its conical surface applies one end end formation contact squeeze that block 2 stretches into stress conduit 4 with above-mentioned stress.Since above-mentioned stress applies
Block 2 can be free to slide in above-mentioned through-hole 41, therefore, it is connect when the conical surface of above-mentioned conical head 11 does not apply block 2 with above-mentioned stress
When touching, stress, which applies block 2, to be submerged in completely in above-mentioned through-hole 41, at this point, operating personnel insert above-mentioned stress conduit 4
Enter in the endoporus of break pin, then, operating personnel rotate above-mentioned screwed pipe 1, and the conical head 11 being allowed to moves and is allowed to bore downward
Face and cutting pin contacts, when conical head 11 continues to move down, it will extrusion stress applies the side wall that block 2 protrudes above-mentioned stress conduit 4
And withstand on to be formed on the inner hole wall of break pin and squeeze, it is connected as with break pin by being interference fitted at this point, above-mentioned stress applies block 2
One, so that the utility model is firm and closely links together with break pin, operating personnel only need screw thread of choosing
Bar 1 just can easily be extracted break pin, simple to operate, of simple structure and strong practicability.
In order to enable the internal thread axle sleeve 3 and the link position of stress conduit 4 in the utility model have enough intensity
The axial force applied when choosing to support, in the present embodiment, limit above-mentioned internal thread axle sleeve 3 and 4 one of above-mentioned stress conduit at
Type.
Embodiment 2：
It can more securely link together with break pin inner hole wall in order to enable above-mentioned stress applies block 2, this implementation
It is further improved on the basis of embodiment 1 in example, in the present embodiment, it is square hole to limit above-mentioned through-hole 41, limits stress and applies
It is square compatible with above-mentioned through-hole 41 to add block 2, in this way so that stress applies block 2 can only be along logical in above-mentioned through-hole 41
Hole 41 is moved, and cannot generate the offset in other directions, enhances stability when the utility model is used, also, the present embodiment
In, apply in above-mentioned stress and can cut into the blade of metal with stretching into the other end that one end is opposite in stress conduit 4 and be provided on block 2
Structure 21.When 11 extrusion stress of above-mentioned conical head applies 2 evagination of block, edge structure 21 will cut into break pin endoporus hole
Wall, so that stress applies block 2 and the connection of break pin endoporus hole wall more fastens.When choosing, due to mainly by
Power face is the upper surface that stress applies block 2, in the present embodiment, sets above-mentioned stress and applies the upper surface of block 2 as plane, thus can
Preferably axial force to be applied on break pin, and then easily facilitates and be pulled out.
As a kind of specific implementation mode of the present embodiment, as shown in Figure 1 to Figure 3, limit above-mentioned stress apply on block 2 with
It is scarf to stretch into the opposite the other end face in 4 one end of stress conduit, and limits the scarf and apply block 2 with above-mentioned stress
Acute angle is set as between upper surface, at this point, above-mentioned knife will be formed between the scarf and the upper surface of above-mentioned stress application block 2
Sword structure 21, the design of this structure and be simple to manufacture conveniently, it is highly practical.
Embodiment 3：
The present embodiment is further qualified on the basis of the above embodiments, in the present embodiment, is limited above-mentioned stress and is applied
One end end face stretched on block 2 in above-mentioned stress conduit 4 is also scarf, which applies the following table of block 2 with above-mentioned stress
Acute angle is set as between face.In this way, just can be preferably bonded with the conical surface of above-mentioned conical head 11, so that conical head 11 pushes stress
Apply the movement of 2 evagination of block.
In order to enable when fastening, conical head 11 and stress apply the connection between block 2 and more consolidate, the present embodiment
In, one end end face in stress conduit 4 and stress application 2 following table of block are stretched on block 2 as shown in figure 3, limiting above-mentioned stress and applying
The oblique angle of acute angle and conical head 11 between face is mutually remaining, in this way, the contact between conical head 11 just can be made to apply block 2 with stress
Area bigger enhances its stability.
Embodiment 4：
A kind of specific implementation mode of the present embodiment as above-described embodiment in the present embodiment, limits above-mentioned through-hole 41
Quantity is 3-5, preferably 4, and there are one above-mentioned stress to apply block 2 for installation in each through-hole 41, in this way, just can
Increase the coupling force between the utility model and break pin.
In order to enable break pin in the circumferential can uniform stressed, in the present embodiment, limit 4 through-holes 41 with stress conduit 4
Axial line centered on circumference array be distributed on the tube wall of stress conduit 4.
Above description is only a specific implementation of the present invention, but the scope of protection of the utility model is not limited to
In this, any one skilled in the art within the technical scope disclosed by the utility model, can readily occur in variation
Or replace, it should be covered within the scope of the utility model.Therefore, the scope of protection of the utility model should be with the power
Subject to the protection domain that profit requires.
