Detailed Description

As shown in FIG. 1, the present invention mainly comprises a drill rod 1 and a fishing assembly 2, and the present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1 and 2, the drill rod 1 is a drill rod in the prior art, a male wire is arranged at a first end of the drill rod, and a female wire is arranged at a second end of the drill rod. The fishing assembly 2 is installed at the first end of the drill rod in a threaded mode, as shown in fig. 3 and 4, the fishing assembly 2 is integrally of a cylindrical structure, an internal thread 1 is arranged at the first end of the fishing assembly, and the first end of the fishing assembly is used for being in threaded connection with the first end of the drill rod.

The terminal surface at the second end of salvaging the subassembly is equipped with mounting groove 22, and the mounting groove is the circular slot, is equipped with latch segment 23 in the mounting groove, and the latch segment can be fixed in the mounting groove, also can the activity set up in the mounting groove.

Be equipped with magnet 3 in the mounting groove, magnet 3 has the ferromagnetism, and magnet is cylindrical, is equipped with the round hole on the axis of magnet. During the installation, be equipped with lock bolt 31 between magnet and latch segment, lock bolt's screw rod pass magnet and with latch segment threaded connection, the outside of mounting groove is arranged in to lock bolt's nut part, is equipped with packing ring 32 between lock bolt's nut part and magnet, lock nut's screw rod part and latch segment threaded connection back, realize fixed to the assembly of magnet with packing ring mating reaction, the terminal surface of magnet and the terminal surface parallel and level of salvaging the subassembly this moment.

During the use, with the drilling rod with salvage the unit mount together, then will salvage the subassembly and in stretching into the drilling towards the drilling, after salvaging the subassembly and reacing drilling bottom, salvage the magnet on the subassembly and can adsorb the cutting edge through magnetic force, extract the drilling rod from the drilling this moment, alright with the salvage of realizing the cutting edge.

As shown in fig. 5 and 6, a second mounting method of the magnet is adopted, in this case, a fixing rod 33 is fixed on the end face of the magnet, a groove 25 is arranged at the bottom of the mounting groove, the groove is a part of the mounting groove, a bearing 26 is fixed on the inner wall of the groove, a locking block 23 is fixed in the inner ring of the bearing, and the lower end of the fixing rod is in threaded connection with the locking block. A hand wheel 4 is fixed at the bottom of the locking block, and teeth which are closely arranged are arranged on the outer wall of the hand wheel. At this moment, contact between magnet cylindrical side wall and the mounting groove inner wall can also set up the inside lining of the annular plastics material of circle between magnet and mounting groove inner wall, and the setting of inside lining plays absorbing effect on the one hand, and on the other hand increases magnet and salvages the frictional force between the subassembly, avoids magnet to drop by oneself after using for a long time. Be equipped with the side opening 24 just to the hand wheel on salvaging the lateral wall of subassembly, when installation or dismantlement magnet, through rack and hand wheel outer wall contact and promote the rotation of latch segment, and then make the dead lever shift up, until with the latch segment separation, magnet shifts out a mounting groove part this moment, can be convenient for take out of magnet. When the magnet is installed, the hand wheel is driven to move reversely.

As shown in fig. 7 and 8, a second embodiment of the present invention is provided. The difference from the first embodiment is that the magnet is installed differently. Fixed block 34 is fixed with in the bottom of magnet, and fixed block 34 is the same with the shape of magnet, puts into the mounting groove with magnet and fixed block during the installation, is equipped with screw 5 at the lateral wall of salvaging the subassembly, realizes through the screw that the locking between fixed block and the salvaging the subassembly is fixed. Correspondingly, a threaded hole matched with the screw is formed in the side wall of the fishing component. The mode of screw connection also is convenient for the installation and the dismantlement of magnet and salvage subassembly.

As shown in fig. 9 and 10, a third embodiment of the present invention is different from the first embodiment in the way of mounting the magnet. As shown in fig. 10, the locking block 23 is movably disposed in the mounting groove 22, a spring 6 is disposed between the locking block and the bottom of the mounting groove, and a driving groove 35 is disposed at the top of the magnet 3, and the driving groove is hexagonal or linear, so that the magnet and the locking block can be mounted and dismounted by a screwdriver or the like. And a tray 36 is arranged at the bottom of the magnet, and the magnet and the locking block are fixedly installed through the tray. During installation, the tray is screwed into the locking block and is in threaded connection with the locking block. The bottom of the locking block is connected with a pull wire 62, and a limiting plate 61 is fixed on the pull wire. In a natural state, the limiting plate 61 is in contact with the second end face of the drill rod. Under the natural state, the mounting groove is arranged in completely to monoblock magnet, and the terminal surface of magnet and the terminal surface parallel and level of salvaging the subassembly. Magnet adsorbs the back with the cutting edge, and to the pulling of drilling rod second end direction for magnet and cutting edge remove in the mounting groove, and then play the guard action to the cutting edge, when pulling out the drilling rod, can avoid cutting edge and drilling inner wall contact and drop like this.

The utility model discloses simple structure can adsorb the cutting edge that drops, and then is convenient for realize the salvage to the cutting edge.
