As a preferred embodiment, lever is the square tube of boring, mitigate weight.
As a preferred embodiment, the front-end and back-end of lever are equipped with inclined installing port, mounting hole is equipped in installing port；
For the installing port of the front end of lever from front upper place inclined downward backward, the inclination angle of the upper surface relative to lever is 45 degree；Lever
Forward downward tilts the installing port of rear end from behind and above, and the inclination angle of the upper surface relative to lever is 45 degree.
As a preferred embodiment, elastic folded plate is spring cold-rolled strip, thickness 1.5-5mm.
As a preferred embodiment, when original state, the inclination angle of lever and mounting plane is 5-15 degree.
As a preferred embodiment, the ratio that fluting is at a distance from lever front end and fluting is at a distance from lever rear end is 1:1 to
2:3。
As a preferred embodiment, the top of fluting is more than the thickness of elastic folded plate at a distance from the upper surface of lever.Ensure thick stick
The normal use of bar will not occur bending or is broken at fluting.
As a preferred embodiment, the middle part of lever is equipped with fluting, the end of the second flanging is inserted into fluting, the end of the second flanging
Portion is sticked to by adhesive in fluting.
The principle of the present invention is：The rotation and reset of lever, elastic folded plate and thick stick are realized with the flexible deformation of elastic folded plate
Bar is fastenedly connected, and ensures that connection will not loosen.
Generally speaking, the invention has the advantages that：It is simple in structure, solve the disadvantage that tradition steps on valve system, it is easy to assembly,
It is stable, balanced most importantly to step on valve dynamics, it is easily controllable.

Specific implementation mode
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
Spring steel steps on valve elastic structure, including lever and elastic folded plate.
Lever is the straight square tube of boring.The middle part of lever is equipped with fluting, and the end of the second flanging is inserted into fluting,
The end of second flanging is welded in fluting, and fluting is opened up perpendicular to the lower face of lever, the width of fluting and elastic folded plate
Thickness corresponds to.The top of fluting is more than the thickness of elastic folded plate at a distance from the upper surface of lever, ensures certain solid thickness,
It avoids being broken.The ratio slotted at a distance from lever front end and slotted at a distance from lever rear end is 2:3.The front end of lever is with after
End is equipped with inclined installing port, and mounting hole is equipped in installing port；The installing port of the front end of lever from front upper place backward lower section
It tilts, the inclination angle of the upper surface relative to lever is 45 degree；Forward downward tilts the installing port of the rear end of lever from behind and above, phase
Inclination angle for the upper surface of lever is 45 degree, inclined installing port is arranged, convenient for lever and other parts for stepping on valve system
Installation.
Elastic folded plate includes the first flanging and the second flanging for being mutually bent into " 7 " font, and the first flanging is fixed on installation
