By technique scheme, before installation, first support card and fixed mount being formed and coordinates, plug-in mounting rotating shaft again after having coordinated, now rotating shaft is supported card and the dual of fixed mount is fixed, and improves the rotating shaft stability when rotation.
This utility model is further arranged to: described support card includes some turned-out fixing feet being converted into shape, and described fixing foot is installed on the both sides of fixed mount respectively.
By technique scheme, the structure of each fixing foot is stamping each through support card, it is ensured that shaping structures is convenient, and efficiency is higher, and support card is lamellar, and it is abundant with the contact area of fixed mount, it is ensured that secure fit is stable.
This utility model is further arranged to: described support card includes the equal diameters for the fixing hole rotating axle traverse, described fixing hole aperture and rotating shaft.
By technique scheme, when fixing hole is inserted in rotating shaft, fit clearance is very little, then ensure that the axiality at its two ends in axis of rotation process, it is to avoid the partial loop variation that rotating shaft is formed in its end, improves the job stability of rotating shaft.
This utility model is further arranged to: described support card includes the angle of interconnective installing plate and connecting plate, described fixing foot and installing plate more than 90 degree.
Pass through technique scheme, in use, fixing foot is installed along its edge near fixed mount, and the grasp opening formed due to the fixing foot of support card homonymy is bigger, facilitate support card and be arranged on fixed mount, it is to avoid card when support card and fixed mount assembling pauses.
This utility model is further arranged to: the junction rounding of described installing plate connecting plate and installing plate.
This utility model is further arranged to: described installing plate and connecting plate form angle more than 90 degree.
By technique scheme, during use, two installing plates and connecting plate form trapezoidal opening, and pressing installing plate makes its bayonet socket reduce and inserts in fixed mount, it is ensured that support card coordinates firmly with fixed mount, and anti-swing ability strengthens.
This utility model is further arranged to: described connecting plate is one or two.
By technique scheme, turning down in forming process in support card, connecting plate can arrange one or more, and when arranging two connecting plates, a connecting plate connects two installing plates, and conflicts in the inner side of another connecting plate and fixed mount, raising cooperation compactness.
This utility model is further arranged to: described support card is copper material.
By technique scheme, adopt metallic copper material to have higher Mechanical Structure Strength, it is to avoid tension failure, and the rust-proofing ability of copper material is better.
In sum, this utility model has the advantages that support card is by rotating shaft support, improves rotating shaft stability on fixed mount, avoids the deformation of rotating shaft self structure simultaneously.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
Embodiment one: the axis body supporting construction of a kind of breaker of plastic casing, including the fixed mount 1 being articulated with in support (not shown), fixed mount 1 is equipped with rotating shaft 2, also including the support card 3 for supporting rotating shaft 2, support card 3 is installed on fixed mount 1, before installation, first support card 3 is formed with fixed mount 1 and coordinate, plug-in mounting rotating shaft 2 again after having coordinated, now rotating shaft 2 is supported the dual fixing of card 3 and fixed mount 1, improves the rotating shaft 2 stability when rotating.
Support card 3 includes some turned-out fixing feet 4 being converted into shape, fixing foot 4 is installed on the both sides of fixed mount 1 respectively, the structure of each fixing foot 4 is stamping each through support card 3, ensure that shaping structures is convenient, efficiency is higher, and support card 3 is lamellar, it is abundant with the contact area of fixed mount 1, it is ensured that secure fit is stable.
Support card 3 includes for the fixing hole 5 rotating axle traverse, the equal diameters of fixing hole 5 aperture and rotating shaft 2, when fixing hole 5 is inserted in rotating shaft 2, fit clearance is very little, so ensure that the axiality at its two ends in rotating shaft 2 rotation process, avoid the partial loop variation that rotating shaft 2 is formed in its end, improve the job stability of rotating shaft 2.
Support card 3 includes interconnective installing plate 31 and connecting plate 32, the angle of fixing foot 4 and installing plate 31 is more than 90 degree, in use, fixing foot 4 is installed along its edge near fixed mount 1, the grasp opening formed due to the fixing foot 4 of support card 3 homonymy is bigger, facilitate support card 3 and be arranged on fixed mount 1, it is to avoid card when support card 3 and fixed mount 1 assemble pauses.
