Boss, the boss are equipped with screw hole, and described spring lever one end is hinged on by axis pin on the screw hole on boss, spring lever
The other end is connect with connecting lever, and the energy-storaging spring is sleeved on spring lever.
Preferably, oval mounting hole there are two being set on the rear and front end of the U-lag both sides.
Preferably, link is equipped on the cabinet of stabilizer blade side, the main shaft is threaded through on link and with connecting
Frame is rotatably connected, and the main shaft is equipped with driven gear.
Preferably, the clutch gear being connected with the clutch and the motor gear being connected with motor are further included, it is described
Clutch gear is meshed with motor gear.
Preferably, the driven gear is meshed with clutch gear.
Preferably, the link is equipped with sub-gate signal microswitch.
Preferably, separating brake signal source and in-place closing signal source in place are equipped on the stabilizer blade below the main shaft.
The beneficial effects of the utility model are：Due to taking above-mentioned technical proposal, the utility model passes through motor and clutch
The folding of switch is realized in the cooperation of device, and theory structure is simple, transmission mechanism is simple, easy to process, installation and adjustment are more convenient
Reliably.
