The specific embodiment
For the present invention is become apparent, hereby with preferred embodiment, and cooperate accompanying drawing to be described in detail below.
The present invention is by utilizing the mechanism principle of riveting gun, and it used on pipe cutter and a kind of plastic pipe cutting knife of design as shown in Figure 1, is a kind of fractionation structural representation of plastic pipe cutting knife.The centre position of cutter hub 1 is connected with flexible handle 17 by bearing pin 6, the both sides of cutter hub 1 also are connected with the first packing ring 4, the first packing ring 4 is connected with jump ring 2 by the first pad 3, so that flexible handle 17 has the self-return function, cover has flexible handle gum cover 18 on the flexible handle 17.As shown in Figure 2, be the structural representation of cutter hub 1.In the universal driving shaft location hole 21 of cutter hub 1 linkage structure is installed, and linkage structure and cutter hub 1 are complementary, the front end of linkage structure is connected with cutter head 5 by the axis hole 19 on the flexible handle 17, cutter head 5 is cutter head running fix groove 20 interior can the slips front and back of cutter hub 1 front end, and the rear end of cutter hub 1 is withstood in the rear end of linkage structure.
As shown in Figure 3, be the structural representation behind a kind of plastic pipe cutting knife removal cutter hub.Universal driving shaft 8 front ends of linkage structure run through universal driving shaft location hole 21, and be connected with cutter head 5, the rear end of universal driving shaft 8 is passed successively the second packing ring 9, locking plate spring 10,2 locking plates 11, release flat springs 12, is separated locking plate 13, the second packing ring 9, cutter head return spring 14, the second pads 15 are connected with screw 16, and withstand the rear end of cutter hub 1 by cutter head return spring 14.Cutter head return spring 14 utilizes the second pad 15 of universal driving shaft 8 back and screw 16 to fix, and plays the pretightning force that retreats to cutter head 5.Wherein, 9 effects of the second packing ring are to connect universal driving shaft 8 and cutter hub 1, universal driving shaft 8 can smooth and easyly be slided in cutter hub 1, and play positioning action.Cover has flexible handle 17 between the locking plate 11 on the universal driving shaft 8 and solution locking plate 13, and the internal diameter of the axis hole 19 on the flexible handle 17 is greater than the external diameter of release flat spring 12.
Implementation procedure of the present invention is as follows:
Such as Fig. 4, shown in Figure 5, be respectively a kind of use state diagram of cutaway view and a kind of plastic pipe cutting knife of plastic pipe cutting knife.Cutter head 5 links with universal driving shaft 8 usefulness cutter head hold-down screws 7, and the movement of cutter head 5 is controlled in the cutter head running fix groove 20 of cutter hub 1.When firmly tightening up flexible handle 17, locking plate 11 contacts with flexible handle 17, utilize the elastic force of locking plate spring 10, compact lock stator 11, make the locking plate 11 generation displacements forward that link to each other with flexible handle 17, because the pressure-acting of locking plate spring 10 makes locking plate 11 that warpages occur, locking plate 11 is with the interlock of universal driving shaft 8, and 5 reaches of band dynamic cutter head are cut.After universal driving shaft 8 reach, in the time of carrying out next time flexible handle 17 return, owing to separate locking plate 13 under the pressure of release flat spring 12, warpage occurs, block universal driving shaft 8, make it can not automatic backing.After flexible handle 17 unclamped, locking plate 11 retreated under the effect of locking plate spring 10, once reach after the preparation.Constantly repeat flexible handle 17 open and closes, cutter head 5 is reach constantly, thereby pipe is cut off.After pipe cuts off, press and separate locking plate 13, solution locking plate 13 is reformed, under 14 effects of cutter head return spring, universal driving shaft 8 just can retreat, and band dynamic cutter head 5 is stepped back automatically.
The present invention is owing to flexible handle 17 each foldings, and the distance that cutter head 5 advances is little, so the power on the flexible handle 17 produces amplification, relatively needs the strength of hand just little, thereby makes the people feel very laborsaving.
