Hook cooperation；The copper sheathing is fixed in the cylindrical hole in the middle part of slide plate, and has tapped through hole in copper sheathing；The spiral shell of the threaded rod
Tapped through hole in line section and copper sheathing cooperates；
The lifting hook lower end be it is hook-shaped, upper side has through-hole identical with slide plate cross sectional shape, has at the top of upper end
Threaded hole；Lifting hook is connect by upper side through-hole with slide plate, and lifting hook can slide in slider groove；Bolt passes through
Lifting hook upper end screw top hole, can fix lifting hook and slide plate.
Further preferred embodiment, a kind of bearing extractor, it is characterised in that: inside the top of threaded rod tip
With screw thread, the top for being changed to different length and outer diameter can according to need.
Further preferred embodiment, a kind of bearing extractor, it is characterised in that: slide plate two sides upper surface has recessed
Slot has the sliding block of protrusion in lifting hook upper side through-hole, can cooperate with the groove of slide plate.
Further preferred embodiment, a kind of bearing extractor, it is characterised in that: the copper sheathing is cylindrical knot
Structure is drilled with axial thread through-hole on cylinder end face；After the abrasion of copper sheathing internal whorl, replaceable copper sheathing.
Beneficial effect
The utility model has the beneficial effects that the utility model simple structure and reasonable design, screwed activity top,
Can be replaced according to the actual situation, the reeded slide plate of both ends band and bolt cooperation it is practical, can the good lifting hook of stationary positioned,
The copper sheathing of fixed thread bar has wearability, resistance to machinability, can increase the service life of extracting tool, and the spiral shell inside copper sheathing
After line abrasion, replaceable copper sheathing, it is not necessary to replace entire slide plate.
The additional aspect and advantage of the utility model will be set forth in part in the description, partially will be from following description
In become obvious, or recognized by the practice of the utility model.
Detailed description of the invention
The above-mentioned and/or additional aspect and advantage of the utility model from the description of the embodiment in conjunction with the following figures will
Become obvious and be readily appreciated that, in which:
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram of top.
Fig. 3 is the top view with reeded slide plate.
Fig. 4 is the three-view diagram of copper sheathing.
Specific embodiment
The embodiments of the present invention are described below in detail, the embodiment is exemplary, it is intended to for explaining this reality
With novel, and should not be understood as limiting the present invention.
In the description of the present invention, it should be understood that term " center ", " longitudinal direction ", " transverse direction ", " length ", " width
Degree ", " thickness ", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outside",
The orientation or positional relationship of the instructions such as " clockwise ", " counterclockwise " be based on the orientation or positional relationship shown in the drawings, be only for
Convenient for description the utility model and simplify description, rather than the device or element of indication or suggestion meaning must have specifically
Orientation is constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention.
As shown in Figure 1, one of the present embodiment bearing extractor by threaded rod 1, across the flexible handle of threaded rod
2, top 3, the both ends of threaded rod tip slide plate 4 with groove, the copper sheathing 5 of fixed thread bar, the torque arm that can be moved on slide plate
The bolt 7 of hook 6 and fixed lifting hook forms.
Internal screw thread is had inside the top of the threaded rod tip, is cooperated by internal screw thread and threaded rod tip external screw thread,
It can according to need the top for being changed to different length and outer diameter in this way.The screw thread rod rear end and the movable hand for passing through threaded rod
Handle vertically connects, convenient for manipulation threaded rod rotation.
With for the cylindrical hole fixed with copper sheathing in the middle part of the slide plate, copper sheathing is mounted in cylindrical hole, and with cunning
Plate tight fit；The copper sheathing cylinder is drilled with axial thread through-hole on end face, for cooperating with the middle part thread segment of threaded rod, works as spiral shell
When rasp bar rotates, it is able to drive copper sheathing and slide plate axial movement.And copper sheathing itself has wearability, resistance to machinability, increases work
The service life of tool, after the abrasion of copper sheathing internal whorl, replaceable copper sheathing.
Slide plate two sides upper surface has groove, for cooperating with lifting hook；The lifting hook lower end is hook-shaped, upper side
