The specific embodiment
As shown in the figure, it is by mandrel 1, locating snap ring 2, slip ring 3, sliding pin 4, sliding sleeve 5, slips 6, retainer 7 and leading cone 8 are formed, locating snap ring 2, slip ring 3, sliding sleeve 5, tubular slips 6 and retainer 7 are placed on the mandrel 1 from top to bottom, locating snap ring 2 lower ends link to each other with sliding sleeve 5 upper ends, slip ring 3 axially is stuck between locating snap ring 2 and the sliding sleeve 5 in the tube hole of sliding sleeve 5, the middle part external cylindrical surface is provided with slideway 11 on the mandrel 1, sliding pin 4 one ends are fixed on the slip ring 3, the other end is positioned at mandrel slideway 11, the top and bottom of slips 6 link to each other with retainer 7 with sliding sleeve 5 respectively, be respectively equipped with inverted cone surface and the inner conical surface that is meshed on mandrel 1 outer wall He on slips 6 inwalls, leading cone 8 links to each other with mandrel 1 lower end.
Mandrel 1 is provided with the cylindrical body of boss 12 for the upper end outer wall, nozzle is provided with internal thread 13 on the mandrel 1, following nozzle is provided with external screw thread 14, the slideway 11 of mandrel 1 is made of axial alternate setting, the long slideway 16 and the short slideways 17 that link to each other by inclined ramp 15, and the inverted cone surface of mandrel 1 includes inverted cone surface 18 and following inverted cone surface 19.Locating snap ring 2 is provided with the cylindrical body that annular snap platform 21, lower end outer wall are provided with external screw thread 22 for the upper end outer wall.Slip ring 3 is for radially being provided with the ring bodies of slip pin-and-hole 31 on the ring wall.Sliding sleeve 5 by cross sunk screw 9 is fixed with slips catch 10 on the link slot 53 for being provided with internal thread 51 and slip ring groove 52 in the last nozzle from top to bottom, descending nozzle to be provided with the cylindrical body of link slot 53 on the slips on the slips.Slips 6 is respectively equipped with the bearing shell shape body of upper binding head 61 and lower union joint 62 for two ends, and the inner conical surface of slips 6 includes inner conical surface 63 and following inner conical surface 64, and its outer wall is provided with salvaging screw thread 65.Retainer 7 is the cylindrical body that last nozzle is provided with link slot 71 under the slips, is fixed with slips catch 10 by cross sunk screw 9 on the link slot 71 under the slips.Hexagonal holding screw 20 in being provided with between locating snap ring 2 and the sliding sleeve 5.
Operating principle: when the leading cone 8 of fishing spear enters fish and continues when descending, slips 6 is at first run into fish, because the effect of fish is drawn slips 6 in, fishing spear continues descending.After slips 6 all entered fish, the fish crown drives sliding sleeve 5, slip ring 3, sliding pin 4, slips 6 and retainer 7 on locating snap ring 2 up with first of fish.Carry fishing spear on this moment, sliding sleeve 5, slip ring 3, sliding pin 4, slips 6 and retainer 7 are descending relatively under the effect of deadweight, because sliding pin slips in the long slideway 16 for 4 this moments, therefore the descending distance of slips 6 is big, under the interaction of the inner conical surface of the inverted cone surface of mandrel 1 and slips 6, fish is blocked in slips 6 expansions, and upper lifting force is big more, clamping force is also big more, thereby realizes fishing.If fish is blocked, be difficult to pick up, can below hit drilling tool, the inner conical surface of slips 6 and the inverted cone surface of mandrel 1 are thrown off, and it is up to promote sliding sleeve 5, slip ring 3, sliding pin 4, slips 6 and retainer 7, because the effect of slide ramp, sliding pin 4 slips into short slideway 17, carry drilling tool on this moment, it is up to drive fishing spear, because sliding pin 4 is in short slideway 17, slips 6 can not drop at the end, therefore the inner conical surface of slips 6 and the inverted cone surface of mandrel 1 can not mesh, and slips does not have tension force to fish 6 this moments, and fishing spear can successfully withdraw from fish.
