Author uses more convenient.
As it is shown on figure 3, in the present embodiment, described switch module 2 includes master switch terminal the 21, second contact chip 22 and arranges
Auxiliary switch terminal 23 above master switch terminal 21, described second contact chip 22 includes main part 221 and the folding of upwards bending
Turn of bilge 222, described auxiliary switch terminal 23 is fixing with the bending part 222 of the second contact chip 22 to be connected, and triggers assembly 5 and drives second to connect
The bending part 222 of contact 22 downwardly turns over so that auxiliary switch terminal 23 contacts with master switch terminal 21, and the circuit i.e. switched closes
Closing, speed-regulating switch is started working.
In the present embodiment, the bending angle between described bending part 222 and main part 221 is 30 degree to 50 degree, bending angle
Spend hour, then, when the main part 221 of the second contact chip 22 is flipped up, can produce interfere triggering assembly 5, affect triggering group
Part 5 drives switch module 2 to close；When bending angle is excessive, then there will be the diastema that the bending part 222 of the second contact chip 22 waves
Excessive, cause speed governing situation the most accurately.
As shown in Figure 4, in the present embodiment, described triggering assembly 5 includes push handle 51 and drives driving of push handle 51 linear motion
Motivation structure, one end of described push handle 51 is connected with drive mechanism, and the other end of described push handle 51 is provided with contact head 52, described in connect
