Abstract
The utility model discloses one and draw horse, it is characterized in that: comprise hand lever, threaded mandrel and hook pawl; The central point of described hand lever and the top vertical welding of threaded mandrel; Described threaded mandrel is threaded with the top margin center hooking pawl, and the bottom of threaded mandrel is polished into the top of epiconus point-like; Described hook pawl is hexagonal hollow nut shape structure, hooks the side rectangle hole open inward of pawl base plane, forms jaws, can catch on gear with the opposite side of base plane.The utility model structure is simply small and exquisite, easy to use to save time, and small-sized electric tool rotor axis of electric and gear can be made to be separated.
Description
Technical field
The utility model relates to motor disassembling tool field, be specifically related to a kind of small-sized electric tool rotor axis of electric and gear are separated draw horse.
Background technology
The motor of the small-sized electric tools such as electric impact drill burns out, coiling again after needing the gear on armature spindle to pull down, due to armature spindle and gear structure small and exquisite, tradition extracting tool cannot use more greatly, often making pounds with a hammer makes its point to take off, and not only easily damages gear, and time-consuming.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art and provides that a kind of structure is simply small and exquisite, easy to use to save time, and what small-sized electric tool rotor axis of electric and gear can be made to be separated draws horse.
For achieving the above object, the technical solution of the utility model is: one draws horse, it is characterized in that: comprise hand lever, threaded mandrel and hook pawl; The central point of described hand lever and the top vertical welding of threaded mandrel; Described threaded mandrel is threaded with the top margin center hooking pawl; Described hook pawl is hexagonal hollow nut shape structure, hooks the side rectangle hole open inward of pawl base plane, forms jaws, can catch on gear with the opposite side of base plane.
The top margin of described hook pawl and the inner ring face on base polish flat, smooth area be top margin, base area 3/4ths.
The bottom of described threaded mandrel is polished into the top of epiconus point-like.
Operation principle: utilize the base jaws hooking pawl to catch on gear, operation hand lever rotates, and threaded mandrel is passed hook the top margin screwed hole of centre of pawl to rotate downwards gradually, after the end points of armature spindle is withstood in the top of threaded mandrel, continue to rotate threaded mandrel, gear will slowly be pulled out.
As shown from the above technical solution, the beneficial effects of the utility model are: 1, structure is simply small and exquisite, can use on the table, and easy to usely save time, and small-sized electric tool rotor axis of electric and gear can be made to be separated.2, waste and old nut or similar hollow can be used to make and to hook pawl, turn waste into wealth.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the front view of hook pawl of the present utility model.
In figure, 1. hand lever, 2. threaded mandrel, 3. hook pawl, 4. jaws, 5. comes directly towards, 6. top margin, 7. base.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
As Fig. 1, shown in 2, the utility model is made up of hand lever 1, threaded mandrel 2 and hook pawl 3; The central point of described hand lever 1 and the top vertical welding of threaded mandrel 2; Described threaded mandrel 2 is threaded with top margin 6 center hooking pawl 3, and the bottom of threaded mandrel 2 is polished into the top 5 of epiconus point-like; Described hook pawl 3 is hexagonal hollow nut shape structure, hooks the side rectangle hole open inward of pawl 3 base 7 plane, forms jaws 4, can catch on gear with the opposite side of base 7 plane; The top margin 6 of described hook pawl 3 polishes flat with the inner ring face on base 7, smooth area be top margin 6, base 7 area 3/4ths, when making hook pawl 3 hook grasping teeth wheel, jaws 4 is face and face contact with gear.
Operation principle: utilize base 7 jaws 4 hooking pawl 3 to catch on gear, operation hand lever 1 rotates, and makes threaded mandrel 2 rotate downwards gradually through top margin 6 screwed hole of centre hooking pawl 3, after the end points of armature spindle is withstood in the top 5 of threaded mandrel 2, continue to rotate threaded mandrel 2, gear will slowly be pulled out.
