Further, connecting lever body also includes the spline stiffening piece of the ring-type located at splined hole at.
Further, the connecting lever body also include axis along the extension of connecting lever body thickness direction, through each connecting lever piece and spline
The square shaft of positioning six of stiffening piece.
Further, bearing pin or rivet both ends are respectively provided with least two connecting lever pieces being brought into close contact.
The spring operating mechanism of the present invention adopts the following technical scheme that：
Spring operating mechanism, including connecting lever, connecting lever include connecting lever body, and its connecting lever is a difference in that with existing connecting lever body：
The connecting lever body includes the connecting lever supporter along the extension of connecting lever thickness direction, the connecting lever located at connecting lever supporter thickness direction both ends
Piece.
Further, each connecting lever supporter is the bearing pin or rivet that axis extends along connecting lever body thickness direction.
Further, connecting lever body also includes the spline stiffening piece of the ring-type located at splined hole at.
Further, the connecting lever body also include axis along the extension of connecting lever body thickness direction, through each connecting lever piece and spline
The square shaft of positioning six of stiffening piece.
Further, bearing pin or rivet both ends are respectively provided with least two connecting lever pieces being brought into close contact.
Usefulness of the present invention is：Because connecting lever body uses laminated structure, the metal plate riveted type of the design is integrated to turn
Arm and connecting lever use metal plate riveted type structure design, the direct punch forming of metal plate parts, are assembled together by riveting process,
Greatly save production and processing cost；Its is simple in construction, and intensity is high, in light weight, good mechanical property；Positioning six square shafts can ensure
The accuracy of relative position between connecting lever piece and spline stiffening piece.

Embodiment
The spring operating mechanism embodiment of the present invention：
The functional part being connected in spring operating mechanism with connecting lever 1 include cam, locking bolt, output pull bar, lock bearing pin and
Splined shaft.Wherein, except connecting lever 1 unlike the prior art in addition to, miscellaneous part refers to the structure shown in Fig. 1.
As shown in Figure 3 and Figure 6, connecting lever 1 includes connecting lever body 11, locking bolt block 12 and roller 13；Connecting lever body 11 includes conduct
Rivet 112 that the axis of connecting lever supporter extends along connecting lever body thickness direction, the connecting lever piece 111c located at the both ends of rivet 112, set
In six square shafts 116 of the spline stiffening piece 113 of the ring-type on the edge of splined hole 117, roller axle 115 and positioning；
Every three of connecting lever piece 111c fits into a connecting lever piece group, respectively connecting lever piece group 111a and connecting lever piece group 111b,
Both are respectively at the both ends of rivet 112；Locking bolt block 12 is between two connecting lever piece groups, is played a supportive role；Connecting lever piece group 111a
Spline stiffening piece 113 is equipped with connecting lever piece group 111b both sides, and spline stiffening piece 113 is fixed on two by bolt mode and turned
In arm pieces group；The intensity of splined hole 117 can be improved using spline stiffening piece 113；Connecting lever piece 111c, spline stiffening piece 113 are equal
For stamping parts, once formed in punching course splined hole 117 along and appearance profile, this reduces processing cost；
In order that roller 12 can be rotated freely, rivet 112 and roller axle 115 made to the both ends diameter of axle is thin, interlude
The thick Step Shaft of the diameter of axle, and the axial length of the two interlude is more than the thickness of the axial direction of roller 13；
The axis of six square shafts 116 is positioned along the thickness direction of connecting lever body 11 to extend, its also cross each connecting lever piece 111c and
Each spline stiffening piece 113, accordingly, connecting lever piece 111c and spline stiffening piece 113 have and the positioning location fit of six square shaft 116
Hexagonal hole, hexagonal hole can be simultaneously once-forming in connecting lever piece 111c and the stamping process of spline stiffening piece 113；Position six sides
116 1 screw threads for being provided with bolt of axle, other end is provided with block disk；So can be to turning in use six square shafts 116 of positioning
Arm pieces 111c and spline stiffening piece 113 play positioning action, prevent between connecting lever piece 111c and connecting lever piece 111c adds with spline
Gu being misplaced between piece 113, positioning precision is improved.
