The lower end of lower slipses 11, and being fixedly connected with body 1, for protecting lower slipses 11, is avoided during tripping in, lower slipses 11 by
The premature setting of packing element component 70 is actuated to upward power.The stress of slips protective case 13 promotes lower slipses 11 and cuts and sit extension shear pin
12, then lower slipses 11 can be up relative to lower slipses tapered sleeve 10.
In one specifically embodiment, lock sleeve 14 is fixedly connected with the lower end of slips protective case 13.The lock sleeve 14
It is socketed on the outer wall of body 1.And lock sleeve 14 is connected with body 1 by starting shear pin 17.It is, slips protective case 13
It is fixedly connected by lock sleeve 14 with body 1.This setup is simple, can easily be processed, and can guarantee that and carry
It is preceding to sit the danger hung and set.Preferably, slips protective case 13 and lock sleeve 14 are threadedly coupled, and are provided with anti-rotation pin 15,
To ensure connective stability between the two.Under power effect, start shear pin 17 and cut, so as to release lock sleeve 14 and body
1 is fixedly connected.Now, under power effect, lock sleeve 14 can promote slips protective case 13, and lower slipses tapered sleeve 10 and lower card
Watts 11 up together (now, sit hang shear pin 12 do not cut), is set with actuating packing element component 70.
In a preferred embodiment, the lower end step formula of lower slipses 11 is socketed in the upper of slips protective case 13
End, and the radial dimension of the periphery wall of slips protective case 13 is not less than the radial dimension of the periphery wall of lower slipses 11.By upper
State and set the seat in advance for being both avoided that lower slipses 11 to hang, also can guarantee that when needing packing element component 70 to set, slips protective case 13
Stable motive force can be provided for lower slipses 11.
Anti-receding device 16 is set between lock sleeve 14 and body 1.The anti-receding device 16 is used to prevent in packing element component 70
After setting, lock sleeve 14 retreats downwards movement, to ensure that packing element component 70 sets security.Anti-receding device 16 is it is so structured that anti-
Move back ratchet and anti-back spine loop type.And this form is well known to those skilled in the art, detailed description is omitted here.
