Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described:
As shown in Figure 1 to Figure 3, by solve drill bit in prior art bored object block time, bore body will rotate backward, and the fast moment of torsion of speed is large, the problem of personal injury is often brought to operator, a kind of electric drill safety device is provided, comprise universal driving device 1, tilt switch 2 and control circuit 3, universal driving device 1 one end is fixedly connected on electric drill by set bolt 4 and bores on body 5, the other end is fixedly connected with tilt switch 2, control circuit 3 comprises double control switch controller 6, double control switch 7, normally closed delay switch 8, tilt switch 2 connects double control switch controller 6 input, double control switch controller 6 output connects double control switch 7, double control switch 7 connects rotating forward control circuit and the reverse turn control circuit of electric drill motor 9, normally closed delay switch 8 is provided with between the reverse turn control circuit of double control switch 7 and electric drill motor 9.
As preferred embodiment, universal driving device 1 comprises the first universal joint 21, second universal joint 22, 3rd universal joint 23, first universal bar 24, second universal bar 25, 3rd universal bar 26, first universal bar 24 is through set bolt 4, set bolt 4 is fixedly connected on electric drill and bores on body 5, first universal bar 24 can rotate around set bolt 4, described first universal bar 24 and the second universal bar 25 right-angled intersection formula are through the first universal joint 21, first universal joint 21 can move axially along the first universal bar 24 and the second universal bar 25, second universal bar 25 and the 3rd universal bar 26 right-angled intersection formula are through the second universal joint 22, second universal joint 22 can move axially along the second universal bar 25 and the 3rd universal bar 26, 3rd universal bar 26 connects the 3rd universal joint 23, 3rd universal joint 23 can relative 3rd universal bar 26 axial rotation, tilt switch 2 is fixedly mounted on the 3rd universal joint 23.
