The contact of four sides, and also change continuous with the continuous position rotating contact point, just then forming a closing
Square.The hole that the technical program is outputed is in the same size, and by the use of general electric tool as power, improves work efficiency, fall
Low labor intensity.
Brief description
Fig. 1 is a kind of structural representation of the square opening device being exclusively used in Wall switch box installation of the present invention；
Fig. 2 is a kind of structural decomposition diagram of the square opening device being exclusively used in Wall switch box installation of the present invention.
Specific embodiment
Below in conjunction with accompanying drawing, lift a specific embodiment and described in detail.
A kind of square opening device being exclusively used in Wall switch box installation, including a shell 1, is provided with eccentric part in shell 1
Mounting groove 11 and axle portion mounting groove 12, the width of eccentric part mounting groove 11 is more than the width of axle portion mounting groove 12, axle portion mounting groove
12 depth is more than the depth of eccentric part mounting groove 11, and eccentric part mounting groove 11 is communicated with axle portion mounting groove 12 and all bottomless, that is,
Eccentric part mounting groove 11 is communicated with axle portion mounting groove 12 and through shell 1.
Activity setting one eccentric shaft 5 in shell 1.In the present embodiment, eccentric shaft 5 includes eccentric part 51 and axle portion 52, partially
The width of center portion 51 is more than the width of axle portion 52, and eccentric part 51 is not fixedly connected not concentricly with axle portion 52, and eccentric part 51 is located at
In eccentric part mounting groove 11, axle portion 52 is located in axle portion mounting groove 12 and extends to outside shell 1.Eccentric part 51 and axle portion 52 are all logical
Cross bearing to be installed in shell 1.In the present embodiment, eccentric part 51 is installed in shell 1 by bearing 1, and axle portion 52 passes through axle
Hold 23 and bearing 34 be installed in shell 1.
External gear 6 is set in the outer end of eccentric part 51 fixed thereto, corresponding, is fixedly installed on eccentric part mounting groove 11
One internal gear 7, external gear 6 and internal gear 7 engaged transmission, in the present embodiment, external gear 6 and internal gear 7 are slide fit（I.e. gap
Engagement）.In the outside of eccentric part mounting groove 11, cutter 8 is set, cutter 8 is threadably secured with external gear 6 and is connected.
Cutter 8 outer setting one outer baffle 9, outer baffle 9 is screwed with eccentric part 51 and is connected.
In the present embodiment, eccentric shaft 5 is rotated by electric tool.This electric tool can be electric hammer, but this
Bright it is not limited to electric hammer.When electric hammer drives eccentric shaft 5 rotation, eccentric shaft 5 drives cutter 8 and external gear 6 around internal gear 7
Rotation, the movement locus of cutter 8 are square, complete the cutting of square hole under the axial impact force of electric hammer meanwhile.
A specific embodiment being only the application disclosed above, but the application is not limited to this, any this area
Technical staff can think change, all should fall in the protection domain of the application.
