Among the figure: 1 heating wire, 2 contact rods, 3 extension springs, 4 protectors, 5 conductive contacts, 6 arm-ties, 7 back-moving springs; 8 insulation boards, 9 conductor strips, 10 screws, 11 through holes, 12 elongated slots, 13 extension spring holes; 14 hinges, 15 snap closes, 16 gaps, 17 inwalls, the big end of 51 conductive contacts, 52 conductive contact small ends.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment.
Embodiment:
Referring to Fig. 1-7, present embodiment mainly is made up of heating wire 1, contact rod 2, extension spring 3, protector 4, conductive contact 5, arm-tie 6, back-moving spring 7, insulation board 8 and conductor strip 9, wherein conductor strip 9 is fixed on the central authorities of insulation board 8 by screw 10, and is connected with protector 4; Insulation board 8 is connected with arm-tie 6; Have through hole 11 on the arm-tie 6, conductive contact 5 passes through hole 11; Back-moving spring 7 is enclosed within on the conductive contact 5, and is positioned at through hole 11; One of conductive contact 5 is rectified the conductor strip on the insulation board 89, and both match each other, and have gap 16 between the two; The other end of conductive contact 5 is connected with extension spring 3; The other end of extension spring 3 is connected with heating wire 1; Heating wire 1 is walked around contact rod 2.
In the present embodiment, arm-tie 6 has elongated slot 12 with the central authorities of insulation board 8 stiff ends; Insulation board 8 is connected with the projection of the both sides of arm-tie 6, and the conductor strip of insulation board 8 central authorities is arranged in the elongated slot 12 of arm-tie 6, and has the space between the arm-tie 6, and conductor strip 9 is not contacted with arm-tie 6.
In the present embodiment, conductive contact 5 is stairstepping, and corresponding with it through hole 11 also is stairstepping; The big end 51 of conductive contact is connected with back-moving spring 7, and the other end of back-moving spring 7 contacts with the inwall 17 of through hole 11; Conductive contact small end 52 passes through hole 11, has extension spring hole 13 on it, and extension spring 3 is passed extension spring hole 13 and is connected with conductive contact 5.
In the present embodiment, insulation board 8 is connected by hinge 14 with a side of arm-tie 6, and opposite side is fixing by snap close 15.During use, can open snap close 15, and 14 open hinge, conductive contact 5 is installed; After the installation, hinge 14 is closed, the snap close of fastening simultaneously 15, insulation board 8 is fixing with arm-tie 6.
In the present embodiment, the quantity of through hole 11 has 144 on the arm-tie 6, and the distance between per two through holes 11 is 1cm.During use, can on different through hole 11, heating wire be installed, cut into the material of different sizes according to the size of foam or the cutting of plastic or other material needs.
During operate as normal, the contact rod 2 of cutting machine both sides is walked around at the two ends of heating wire 1 respectively, and fixed strain.Because an end of heating wire 1 is connected with extension spring 3, so heating wire 1 spurs extension spring 3, and extension spring 3 spurs conductive contact 5 again, and conductive contact 5 those little ends are pulled out through hole 11, and big that end of conductive contact 5 is in through hole 11, and has gap 16 between the conductor strip 9; At this moment, back-moving spring 7 is in compressive state.
When heating wire 1 fracture suddenly, back-moving spring 7 reduces from compressive state; Be subjected to the active force of back-moving spring 7, conductive contact 5 those big ends pass from through hole 11, just contact with conductor strip 9 on the insulation board 8, make conductor strip 9 energisings; Because conductor strip 9 is connected with protector 4, protector 4 is started, thereby cut off the power supply of whole device, play the effect of protection.
In addition, need to prove, specific embodiment described in this specification, as long as the undeclared concrete shape and size of its part, then this part can be Any shape and the size that adapts with its structure; Simultaneously, the part title of getting also can be different.Allly conceive equivalence or the simple change that described structure, feature and principle are done, be included in the protection domain of the utility model patent according to the utility model patent.
