In the later operation process, the connecting rod 7 adjustment unit can be driven by the deceleration rocker arm 5 unit to perform reciprocating movement adjustment as a whole. The deceleration rocker arm 5 unit includes two parts: a deceleration gear set 3 and an adjustable connecting rod 7 assembly 4; the deceleration gear set 3 is externally connected to a corresponding DC motor 10, which can enhance the torque generated by the DC motor 10; the adjustable connecting rod 7 assembly 4 is connected to the deceleration gear set 3 through the rocker arm 5, and can perform corresponding linkage adjustment. The rocker arm 5 is rotatably connected to the deceleration gear set 3, and can perform a rotation adjustment operation within a predetermined range driven by the deceleration gear set 3. In the later operation process, the torque generated by the DC motor 10 is enhanced by the reduction gear set 3 and then converted into reciprocating power through the rocker arm 5 and the adjustable connecting rod 7 assembly 4. Embodiment 2:

[0015] On the basis of the first embodiment, the connecting rod 7 adjustment unit includes two parts: the connecting rod 7 fixing frame 6 and the connecting rod 7; the connecting rod 7 fixing frame 6 is connected to the positioning plate 2, has a predetermined operating size and supporting force, and is provided with a through hole of a predetermined operating size, which can perform corresponding connection and limiting operations; the connecting rod 7 is connected to the adjustable connecting rod 7 assembly, has a predetermined operating length and supporting force, and passes through the through hole provided by the connecting rod 7 fixing frame 6, and can follow the linkage of the adjustable connecting rod 7 assembly to adjust the corresponding operating position.

[0016] Based on the above embodiments, the working process of the utility model is as follows: when the frequency regulator 11 is connected to the 220 power supply, the operating speed of the 3-12v DC motor 10 can be accurately controlled by selecting the appropriate frequency through the knob switch. The torque generated by the motor is enhanced by the reduction gear and converted into reciprocating power through the rocker arm 5 and the adjustable connecting rod 7 assembly 4, and this power is then transmitted to the connecting rod 7. The connecting rod 7 then applies the reciprocating force to multiple self-resetting brake power-off devices. With the action of the reciprocating force, the self-resetting brake power-off device can realize the on and off of the circuit. At the same time, the counter 9 counts according to the on and off state of the self-resetting brake power-off, so as to realize the statistics and detection of multiple targets in one detection at multiple speeds.
