Especially, above-mentioned electronic signal is criticized the signal of automatic outage for this electric screw of control.
Compared to prior art, electric screw of the present invention is criticized and can be regulated the electric screwdriver working pressure, and can set different pressure parameter values as required, and cooperatively interact by magnetic induction switch and magnet pad and can realize reminding the user more can control electric screw to criticize direct outage when the user exerts oneself can send when excessive information warning.
For purpose of the present invention, structural feature and function thereof are had further understanding, conjunction with figs. is described in detail as follows now:
[description of drawings]
Fig. 1 illustrates the structural representation that electric screw of the present invention is criticized.
Fig. 2 illustrates the STRUCTURE DECOMPOSITION schematic diagram that electric screw of the present invention is criticized.
Fig. 3 illustrates the side sectional view that electric screw of the present invention is criticized structure.
[specific embodiment]
With reference to Fig. 1, Fig. 2 and shown in Figure 3, it is respectively the structural representation that electric screw of the present invention is criticized; The STRUCTURE DECOMPOSITION schematic diagram that electric screw of the present invention is criticized; Electric screw of the present invention is criticized the side sectional view of structure.
The invention provides a kind of electric screw and criticize, it comprises:
Electric screwdriver rotating shaft 2, the one end is located in the above-mentioned electric screwdriver seat 1 near above-mentioned magnetic induction switch 13, this end also is provided with several first chutes 21 (this first chute 21 is four in present embodiment), the surface in these electric screwdriver rotating shaft 2 centre positions is provided with screw thread, and also is provided with draw-in groove 22 and two locating holes 23 away from an end of above-mentioned electric screwdriver seat 1;
Adjusting yoke 3, it is located in the above-mentioned electric screwdriver rotating shaft 2, and this adjusting yoke 3 is provided with several travellers 31 (this traveller 31 is four in present embodiment), and this traveller 31 places above-mentioned first chute 21 respectively and extends above-mentioned electric screwdriver rotating shaft 2;
Magnet pad 4, it is located in the above-mentioned electric screwdriver rotating shaft 2, be provided with a spring 5 between this magnet pad 4 and the above-mentioned conciliation pull bar 3, and on end-acted one first stopper section 24 in above-mentioned electric screwdriver rotating shaft 2 of this magnet pad 4, can produce an electronic signal during above-mentioned magnetic induction switch 12 certain positions of this magnet pad 4 distances, this electronic signal can control that electric screw is wholesale to be gone out this information warning of an information warning and can be caution sound, indicator lamp signal, and this electronic signal more can be controlled electric screw and cuts off the power supply automatically;
Adjusting knob 6, its inside be provided with screw thread and with above-mentioned electric screwdriver rotating shaft 2 on threads engaged, one end of this adjusting knob is provided with one second stopper section 61, matches with the traveller 31 of above-mentioned adjusting yoke 3 in this second stopper section 61, and controls this adjusting yoke 3 and slide in above-mentioned electric screwdriver rotating shaft 2;
