Process velocity.
As the further improvement of the above-mentioned breaker energy storage instruction device of the utility model, the groove in energy storage axle is rectangle
Slot, convenient for the groove in energy storage axle machining and be conducive to transmitting of the rotation to cam and connecting plate in energy storage axle.
As the further improvement of the above-mentioned breaker energy storage instruction device of the utility model, cam and connecting plate are along energy storage between centers
Every arrangement.The position that cam and connecting plate are installed in energy storage axle keeps a distance, convenient for cam and connecting plate in energy storage axle
It installs and is connected and fixed.
Detailed description of the invention
The structural schematic diagram of Fig. 1 the utility model breaker energy storage instruction device embodiment 1；
The link configuration schematic diagram of Fig. 2 the utility model breaker energy storage instruction device embodiment 1；
In figure: 1- breaker division plate；2- energy storage axle；3- magnetic blow-out pressing plate；4- indicates axis；5- energy storage direction board；6- rectangular channel；
7- connecting plate (7.1- through-hole；7.2- keyway)；8- cam.
Specific embodiment
1 structure of the utility model breaker energy storage instruction device embodiment as shown in Figure 1, link configuration as shown in Fig. 2, should
Device includes two parallel breaker division plates 1, and the instruction axis 4 being parallel to each other and energy storage are equipped between two breaker division plates 1
Axis 2 is equipped with energy storage direction board 5, magnetic blow-out pressing plate 3 and reduction torsion spring on instruction axis 4；Cam 8 is installed in energy storage axle 2 and is connected
Plate 7 offers the same groove for cooperating respectively with cam 8 and 7 key of connecting plate in energy storage axle 2, same in the present embodiment
Groove is rectangular channel 6；Through-hole 7.1 and the keyway 7.2 for cooperating with 2 key of energy storage axle are offered on connecting plate 7；Cam 8 and company
Plate 7 is fixed in energy storage axle 2 with the cooperation of 2 key of energy storage axle respectively, and cam 8 and connecting plate 7 are along 2 arranged for interval of energy storage axle；2 turns of energy storage axle
