Specific implementation mode
The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning
Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginseng
The embodiment for examining attached drawing description is exemplary, and is only used for explaining the utility model, and cannot be construed to the utility model
Limitation.
Fig. 1 to Fig. 4 is please referred to, Fig. 1 is the whole axonometric drawing of the utility model；Fig. 2 is the front view of Fig. 1；Fig. 3 is Fig. 1
Right view；Fig. 4 is the sectional view of Fig. 1；The utility model embodiment provides a kind of clamping device of cylinder base part, special
Sign is, including：Fixed arm 1 and lever arm 2；The lever arm 2 includes handle 3 and claw 4；The claw 4 is arcuation, one
End is fixedly connected with one end of handle 3；The lever arm 2 is arc, and one end is hinged with the fixed arm 1, and hinged point
In the handle 3 and 4 junction of the claw；The claw 4 cooperatively forms C character form structures with the fixed arm 1.
When specifically used, Fig. 5 is please referred to, Fig. 5 is structural schematic diagram when the utility model is used.By claw 4 and fix
