Description
Technical Field
The utility model relates to a novel bolt extractor.
Background
At present, in the production process of machinery or other industries, bolt fixing connection is widely adopted. Bolts sometimes wear, rust and break, but when broken, their threaded ends remain in the equipment and their hexagonal mounting and dismounting ends break. The existing nail puller used by woodworkers is provided with a nail puller, a clamp, a claw hammer, a vice and other clamping tools for clamping a nut or a bolt for disassembly, a large amount of manpower is consumed in the disassembly process, the disassembly is difficult, no proper tool is used for taking out the threaded end of the bolt from equipment, the replacement of the bolt, the maintenance of the equipment and the normal operation of production can be seriously influenced, and production accidents can be caused sometimes.
Therefore, it is necessary to develop a new bolt extractor to solve the above problems.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a novel bolt extractor can reach the effect of dismantling wearing and tearing fast, getting rusty and fracture bolt.
In order to solve the problems, the technical scheme adopted by the utility model is that the novel bolt extractor comprises a screw rod and a bolt adapter; the hob upper end outside be the external screw thread, the lower extreme is the polished rod, the hob top links to each other with annular handle, the bottom is equipped with axial internal thread hole, the hob lower extreme passes the sheath and stretches out in the outside of sheath, sheath center department be equipped with hob upper end external screw thread matched with internal thread hole, the bolt adapter be both ends all have the adapter of external screw thread, the internal thread hole of upper end external screw thread and hob bottom cooperatees, the internal thread hole of lower extreme external screw thread and the bolt end of waiting to extract cooperatees.
Preferably, the material of the screw rod is stainless steel.
Preferably, the sheath is cylindrical.
Preferably, the handle is provided with a holding area, and the holding area is provided with a groove.
Preferably, the bolt adapter is made of hard alloy.
The utility model has the advantages that:
the utility model has the advantages of simple and reasonable structure, as long as the rotation through the hob just can be very convenient dismantle the bolt get off. Different screw holes through opening on the bolt set up different bolt adapters, can take out the bolt of overwhelming amount basically, and the difficult damage of tooth's socket in the bolt adapter that carbide processing formed can bear huge torsion, just the utility model discloses simple structure, small in size, convenient to use, low in manufacturing cost, advantages such as portable and deposit.

Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
As shown in fig. 1, a novel bolt extractor comprises a screw rod 1 and a bolt adapter 2; the outer side of 1 upper end of hob be the external screw thread, 1 lower extreme of hob is the polished rod, 1 top of hob links to each other with annular handle 3, 1 bottom of hob is equipped with axial internal thread hole, 1 lower extreme of hob pass sheath 4 and stretch out in the outside of sheath 4, 4 center departments of sheath be equipped with 1 upper end external screw thread matched with internal thread hole of hob, bolt adapter 2 for both ends all have the adapter of external screw thread, the internal thread hole of upper end external screw thread and 1 bottom of hob cooperatees, the internal thread hole of lower extreme external screw thread and the bolt end of waiting to extract cooperatees.
The nut of the bolt to be disassembled is disassembled, a drill bit with a proper specification is selected according to the diameter of the bolt to drill a hole in the center of the broken bolt, the corresponding bolt adapter 2 is selected, the lower end adapter of the bolt adapter 2 is connected with the broken bolt, the upper end of the bolt adapter is connected with the bolt rod 1, the handle is rotated anticlockwise, and the broken bolt can be taken out by holding the sheath 4 with hands.
The utility model has the advantages of simple and reasonable structure, as long as the rotation through hob 1 just can be very convenient dismantle the bolt get off. Different screw holes through opening on the bolt set up different bolt adapters, can take out the bolt of overwhelming amount basically, and the difficult damage of tooth's socket in the bolt adapter that carbide processing formed can bear huge torsion, just the utility model discloses simple structure, small in size, convenient to use, low in manufacturing cost, advantages such as portable and deposit.
It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
