Axis device is fixedly connected with a rotation axis, then rotation axis is used to be sequentially connected with the first flexible blade guard and the second flexible blade guard
Mode.But the detection in place of existing driving mechanism mostly uses and coaxially fixes a banking stop with rotation axis, and in support frame
Travel switch is installed, when flexible blade guard is rotated in place, banking stop turns to travel switch under the drive of rotation axis on frame
Position and the contact for triggering travel switch stop operating to control driving motor by central processing unit.
But being triggered between driving motor stops from travel switch has certain buffer time, therefore, banking stop continues
One section of buffer distance is rotated, banking stop is often led to and accident hair that is excessive and then damaging travel switch is caused stress to travel switch
It is raw, the normal opening and closing of protective cover are influenced, and increase equipment input cost.Meanwhile when travel switch fails
When, because that can not find in time, often lead to flexible blade guard rotation excessively, the switch obstacle in turn resulting in protective cover is set with other
Standby damage, and largely effect on charge efficiency.
