On pipe 10, a part for anchor fluke 20 is in protective case 30.Optionally, interior spiral shell is offered in the inner circumferential wall of protective case 30
Stricture of vagina, a part for anchor fluke 20 are threadedly coupled with protective case 30.
Optionally, keeper 31 is installed on protective case 30.Keeper 31 is used for being positioned at and Taper Pipe 10 anchor fluke 20
Ladder platform 11 be separated position so that anchor fluke 20 can be constantly in contraction state.The anchor fluke 20 of contraction can be de- with fish
Open, so that fishing spear exits fish chamber.
Optionally, keeper 31 is pinning.Optionally, have, on Taper Pipe 10, the part being engaged with pinning, so that anchor fluke 20
It is in and 11 detached contraction state of ladder platform.
Fig. 2 shows the structure of the Taper Pipe 10 in fishing spear of the present utility model, offers L-shaped groove 13, L-shaped on Taper Pipe 10
Groove 13 is coordinated with pinning, with position deployed position that anchor fluke 20 contacted with ladder platform 11 and with 11 detached punctured bit of ladder platform
Put.If fish meets card during salvaging, lower drain line is promoted Taper Pipe 10, anchor fluke 20 to be separated with ladder platform 11 and shunk, is continued
Propulsion Taper Pipe 10, until 13 end of L-shaped groove on Taper Pipe 10 props up pinning, rotates Taper Pipe 10, and it is laterally recessed that pinning enters Taper Pipe 10
Groove, the state so that anchor fluke 20 remains retracted, the anchor fluke 20 of contraction are disengaged with fish chamber, above carry oil pipe, and fishing spear smoothly can be moved back
Go out.
Optionally, top connection 40 is provided with Taper Pipe 10, and top connection 40 is sleeved on the second end of Taper Pipe 10, auxiliary for connecting
Assistant piece.Optionally, the circumference along top connection 40 opens up groove, to increase the static friction between top connection 40 and auxiliary member.Can
Choosing, auxiliary member can be oil pipe.
As shown in figure 1, in the present embodiment, adjusting set 50 is additionally provided with, adjusting set 50 is movably disposed on Taper Pipe 10
Between top connection 40 and protective case 30, and it is connected with top connection 40.The effect of adjusting set 50 is for adjusting which with protective case 30
Between spacing distance.When salvaging fish chance calorie requirement exits fishing spear, the state in order that anchor fluke 20 remains retracted needs to promote
Taper Pipe 10, makes the pinning on protective case 30 enter the transverse concave groove of L-shaped groove 13.When due to adjusting set 50 and the interval of protective case 30
During the too small transverse concave groove for causing pinning to cannot be introduced into L-shaped groove 13, can be adjusted by adjusting set 50, with increase with protective case 30 it
Between interval, until pinning can enter the transverse concave groove of L-shaped groove 13.
Optionally, the first screwed hole 41, the first screwed hole 41 and screw fit are provided with top connection 40, to connect in fixation
40 and the relative position of Taper Pipe 10.Optionally, the position on Taper Pipe 10 near the second end offers circumferential recess 14 week, on
After 40 sets of joint is attached on the second end of Taper Pipe 10, the first screwed hole 41 thereon is faced the circumferential recess on Taper Pipe 10
14, it is inserted into screw, you can top connection 40 is fixed on Taper Pipe 10, comes off from Taper Pipe 10 so as to avoid top connection 40.
Optionally, the second screwed hole 42, the second screwed hole 42 and screw fit are provided with top connection 40, for fixed tune
Spacing distance between section set 50 and protective case 30.Optionally, four the second screw threads have uniformly been opened up in the circumference of top connection 40
Hole 42, can repeatedly adjust the spacing distance with protective case 30 to meet one circle of rotation of adjusting set 50.
Optionally, there is interval between protective case 30 and top connection 40, on Taper Pipe 10, is cased with spring 60, spring 60 is arranged on
Protective case 30 and the interval of top connection 40.If fish meets card during salvaging, lower drain line promotes top connection 40, above connects
40 push the springs 60, spring 60 are compressed, and when 13 end of L-shaped groove on Taper Pipe 10 props up pinning, rotate oil pipe, and pinning is entered
10 transverse concave groove of Taper Pipe, locking spring 60, the state so that anchor fluke 20 remains retracted, the anchor fluke 20 of contraction are disengaged with fish chamber, on
Oil pipe is carried, fishing spear smoothly can be exited.
As can be seen from the above description, this utility model the above embodiments achieve following technique effect：
When salvaging fish, using oil pipe by fishing spear lower going-into-well bottom to top of fish, anchor fluke is probeed into fish inner chamber, continue decentralization
Oil pipe, promotes Taper Pipe, anchor fluke to depart from the ladder platform on Taper Pipe, and anchor fluke retracts into threaded interior, down on during target range
Fishing spear is carried, is moved on Taper Pipe, anchor fluke is contacted with the ladder platform on Taper Pipe and opened, the anchor fluke clamping fish female thread after opening,
Fishing spear is carried in continuation realizes that fish is salvaged.
If fish meets card during salvaging, lower drain line promotes top connection, top connection push the spring, spring to be compressed,
When the L-shaped groove end on Taper Pipe props up pinning, oil pipe is rotated, pinning enters Taper Pipe transverse concave groove, and locking spring, so that anchor fluke
Remain retracted state, and the anchor fluke of contraction is disengaged with fish chamber, above carries oil pipe, and fishing spear smoothly can be exited.
Preferred embodiment of the present utility model is the foregoing is only, this utility model is not limited to, for this
For the technical staff in field, this utility model can have various modifications and variations.All of the present utility model spirit and principle
Within, any modification, equivalent substitution and improvements that is made etc. are should be included within protection domain of the present utility model.
