Specific implementation mode
The preferred embodiment of the utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear to be made to the scope of protection of the utility model
Define.
- 2 are please referred to Fig.1, the utility model provides a kind of technical solution：A kind of effective device for limiting of oil inner sleeve, including
Cylindrical hollow shell 1, the cylindrical hollow shell 1 are provided centrally with the centre bore 2 for being connected to its both ends of the surface, the cylindrical hollow
There are three the columnar projections structure 3 with its integral structure, the inside of the cylindrical hollow shell 1 is set for the outside setting of shell 1
The hollow section 4 in middle part there are three setting, the cylindrical hollow shell 1 is outer positioned at being internally provided with for each columnar projections structure 3
The hollow section 6 in portion, and the hollow section 4 in one end connection middle part in the external hollow section 6, the cylindrical hollow shell 1 it is interior
Portion's setting is there are three inner hollow section 7, and the other end in the hollow section in one end connection middle part 4 in the inner hollow section 7,
The central circular hole 5 for being internally provided with hollow section 4 in the middle part of connection three of the cylindrical hollow shell 1, the external hollow
The inside in section 6 and inner hollow section 7 is separately installed with first piston plate 8 and second piston plate 9, and the first piston plate
8 and the center of 9 end of second piston plate be separately installed with feeler lever 10 and push rod 11, the body of rod of the feeler lever 10 runs through the column
