4, between described package main body and the first fixed part, it is provided with elastic reset part, uses elastic reset part
Afterwards, after packing device is opened, the first fixed part can stretch out faster and be supported, at packing device
After closedown, the first fixed part can quickly be retracted reset.
5, drive mechanism is also included, when packing device opens or closes, permissible by this drive mechanism
Control the position of the first fixed part, such as:
A, packing device also include Moveable lid body and rotating shaft, and Moveable lid body is installed on by rotating shaft activity
On package main body;Described drive mechanism is lever, is provided with fulcrum on described package main body, and described lever is pacified
Be loaded on fulcrum, the movable edge of described first fixed part, described Moveable lid body, described fulcrum and lever it
Between formed lever construction.Now, the fulcrum of lever may be located at the middle part of lever, it is also possible to is positioned at lever
One end.
B, described package main body include matrix and the pull body being movably arranged in matrix, when pull body pulls out base
During body, pull body depresses the first fixed part, and is supported by the first fixed part.
C, described drive mechanism are cam, and when Moveable lid body opens or closes, rotating shaft drives cam rotation,
And then control the movement of the first fixed part.
D, controlled by the top-pressure part (or the top-pressure part being connected with Moveable lid body) on Moveable lid body
The movement of the first fixed part.
It should be understood that
Aforementioned " first ", " second " are not for quantity or the restriction of order, and are only used for title
Differentiation;Aforementioned " middle part of lever " is not necessarily referring to the absolute medium position of lever, and is only and two ends
Position relatively;Aforementioned " closing " is not definitely to close, and " opening " the most not fully opens, both
Also it is only the statement of relativeness;Aforementioned " absorption " can be to pass through frictional contact, it is also possible to is logical
