With reference to attached drawing, the disclosure of the utility model will be apparent.It is to be appreciated that these attached drawings are only schematic
, it is not drawn on scale and is also not intended to limit the scope of the utility model.In figure：
Fig. 1 is the schematic diagram of the drive motor for compressor extracting tool of the utility model；
Fig. 2 is the sectional view along A-A of Fig. 1；
Fig. 3 is the use state diagram of the drive motor for compressor extracting tool of the utility model.
Specific implementation mode
Explain specific embodiment of the present utility model in detail with reference to the accompanying drawings.
As shown in Figures 1 to 3, the drive motor for compressor extracting tool of the utility model, including mounting flange 10, revolving part
20 and can run through the motor shaft 101 the fixed link 30 for axially penetrating through hole.
The mounting flange 10 is equipped with the first centre bore 11, and first centre bore 11 is equipped with the first internal thread 111, described
The fixing bolt 12 that can be connect with the motor shaft 101 is additionally provided on mounting flange 10.The revolving part 20 is equipped with and institute
The first external screw thread 22 of the first internal thread 111 cooperation is stated, the revolving part 20 is equipped with the second centre bore (unmarked in figure), described
Second centre bore is equipped with the second internal thread 21.The fixed link 30 pass through first centre bore 111, the one of the fixed link 30
End is equipped with the second external screw thread 31 coordinated with second internal thread 21, and the other end is equipped with can be with 201 screw thread of head axis
The third external screw thread 32 of connection；First external screw thread 20 is opposite with the thread rotary orientation of second external screw thread 31.
First external screw thread 20 is left hand thread, that is, reverse thread.Second external screw thread 31 is right-handed thread
Namely forward screw thread, third external screw thread 32 are also forward screw thread.
The mounting flange 10, which is equipped with, can limit the fastening screw 13 that the mounting flange 10 circumferentially rotates.It is described fixed
Position bolt 13 is inserted into the bolt hole of rear end cap 102 of the driving motor 100, prevents mounting flange 10 from occurring to turn
It is dynamic.
The drive motor for compressor extracting tool of the utility model, in the motor shaft 101 for dismantling driving motor 100
When, motor shaft 101 is first axially penetrated through into the stud in hole and is disassembled, then tears the drive motor for compressor of the utility model open
