Connecting shaft 5 is hinged；It is hinged on the lever A3 by hinge A33 on fixed seat A32, the lever B4 and passes through hinge
B43 is hinged fixed seat B42；Screwed hole is opened up on the fixed seat A32, through hole, in addition to one are opened up on the fixed seat B42
The adjusting screw 6 that individual epimere is thread segment, hypomere is light bar segment, the thread segment coordinates with the screwed hole, the light bar segment
It is spirally connected with the through hole, the upper end of the adjusting screw 6 opens up the notch that available straight screwdriver rotates the adjusting screw 6
61, the position that the fixed seat B42 upper and lower sides are corresponded in the adjusting screw 6 opens up through hole 62, is inserted in the through hole 62
Pin 9；Also sheathed spring 7 in the adjusting screw 6, one end of the spring 7 be connected to the lower surface of the fixed seat A32,
The other end is connected to the lower surface of the fixed seat B42.
Further, the thread segment of the adjusting screw 6 is spirally connected a locking nut 8 after passing through the screwed hole.
Further, two pads 10 are also arranged in the adjusting screw 6, the pad 10 is separately positioned on the spring
Between 7 both ends and the fixed seat A32 and fixed seat B42.
Compared with prior art, the utility model need not change the position of cam with regard to that can cause the change of distributor contact position
It is dynamic, there is the characteristics of simple in construction, easy to adjust.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is Fig. 1 left view.
Embodiment
The technical solution of the utility model is clearly and completely described below in conjunction with accompanying drawing, it is clear that described
Embodiment is the utility model part of the embodiment, rather than whole embodiments.Based on the embodiment in the utility model, sheet
The every other embodiment that field those of ordinary skill is obtained under the premise of creative work is not made, belongs to this practicality
Novel protected scope.
, it is necessary to explanation in description of the present utility model, term " " center ", " on ", " under ", it is "left", "right", " perpendicular
Directly ", the orientation of the instruction such as " level ", " interior ", " outer " or position relationship are based on orientation shown in the drawings or position relationship, are only
Described for the ease of description the utility model and simplifying, rather than instruction or imply signified device or element must have it is specific
Orientation, with specific azimuth configuration and operation, therefore it is not intended that to limitation of the present utility model.In addition, according to art
Language " A ", " B ", it is only used for describing purpose, and it is not intended that instruction or hint relative importance.
, it is necessary to which explanation, unless otherwise clearly defined and limited, term " are pacified in description of the present utility model
Dress ", " connected ", " connection " should be interpreted broadly, for example, it may be fixedly connected or be detachably connected, or integratedly
Connection;Can be mechanical connection or electrical connection;Can be joined directly together, can also be indirectly connected by intermediary,
It can be the connection of two element internals.For the ordinary skill in the art, above-mentioned art can be understood with concrete condition
Concrete meaning of the language in the utility model.
A kind of combined type lever assembly, including the A faces 31 abutted with cam 1, the B faces 41 abutted with distributor contact 2, institute
The right flank that A faces 31 are lever A3 is stated, the B faces 42 are lever B4 left surface, and the lever A3 and the lever B4 pass through
Connecting shaft 5 is hinged；It is hinged on the lever A3 by hinge A33 on fixed seat A32, the lever B4 and passes through hinge
B43 is hinged fixed seat B42；Screwed hole is opened up on the fixed seat A32, through hole, in addition to one are opened up on the fixed seat B42
