As shown in Figure 8; The claw 322 that said blade paw 32 is provided with installation portion 321 and extends to form from installation portion 321; Said installation portion 321 is provided with installing hole 323, said blade paw 32 through screw pass installing hole 323 be threaded with sidewall 314a, last through hole 314c, the 315c of 315a be fixed on said sidewall 314a, 315a is last.And said claw 322 is bent to form from

installation portion

321, and 322 of this claws are used to be pressed on blade 33, with blade 33 be fixed on sidewall 314a, 315a is last.

See also Fig. 1 and shown in Figure 5, said locating flange 4 is provided with flat flange main body 40, and it has level and smooth surface this flange main body 40.This flange main body 40 heart therein is provided with perforate 41, is provided with several screws 42 near a circumference of perforate 41.Said cavity is provided with sloping platform 11 at its outer surface, and corresponding said screw 42 is provided with screw on the said sloping platform 11, and said locating flange 4 cooperates simultaneously through the screw 42 of bolt and locating flange 4 and screw on the sloping platform 11 and is fixed on the cavity.Said flange main body 40 also is provided with some locating holes 43, and these locating holes 43 are positioned on four angles of this locating flange 4, and said external equipment (being valve) is provided with some reference columns (not shown), and said locating hole 43 is enclosed within said reference column and positions.The horizontal plane of said flange main body 40 also provides a datum level for this cutting element 100.

See also Fig. 1 and shown in Figure 6; Said motor terminal pad 6 has with the identical shape of motor 5 tail ends and which is provided with some screws 60; Said cavity correspondence is provided with some screws (not shown), and said motor terminal pad 6 links together through bolt and cooperating of screw 60 with cavity.The flange 62 that said motor terminal pad 6 is provided with circular terminal pad body 61 and is extended to form by terminal pad body 61, said screw 60 is arranged on the said flange 62, and said motor 5 is snap-fit attachment on the upper cavity 2 through this terminal pad 6 and cavity.On the said motor 5 also correspondence be provided with some screws (not shown), said motor 5 and motor terminal pad 6 are installed together through screw.

In original design, we are the big disk that radius forms with the size of motor terminal pad 6 for the center by edge to the body of flange, and disk is big like this; Whole cutting element is to be carried by manpower to be mounted in the valve system; Weight is too heavy, inconvenience is installed, and disk takes up space greatly also very much.Present design has then reduced the area and the volume of disk relatively, has also reduced weight.

See also shown in Figure 1ly, said motor 5 provides driving force for whole cutting element, and this motor 5 can provide positive and negative two kinds of driving forces, thereby is applicable to the different demands in different operating stage.When motor 5 provides the power that is rotated in the forward; Cutter tip 3 clockwise rotates under the drive of driving force that (we define clockwise for just changeing; But also can be for rotating counterclockwise), at this moment, the blade 33 that is positioned at diverse location cuts described outer step surface, sealing surface and inclined-plane respectively.After cutting was accomplished, motor 5 can provide a driving force opposite when cutting for cutter tip 3, and cutter tip 3 rotates counterclockwise (being backward rotation) under the drive of driving force; At this moment, blade 33 can against before direction rotate, the soft flocks around the blade 33 of being deposited in that cuts that the back produces is produced a reaction force and its cleaning is gone out; Thereby be convenient to withdrawing; Simultaneously, can prevent that soft flocks from falling in the valve, influence the operate as normal of whole system.

See also Fig. 1 and Fig. 7, said cutting element 100 also comprises the feed shelter 7 between cutter tip 3 and motor 5 that is installed on the said cavity, and said locating flange 4 is between said cutter tip 3 and feed shelter 7.Said feed shelter 7 comprises operation board 71 and is installed in first helical gear 72 on the operation board 71.Be provided with second helical gear (not shown) between said cavity and the installation main body, said second helical gear and first helical gear 72 are connected.When operating personnel's rotating operation dish 71, operation board 71 drives first helical gear 72 and rotates, and first helical gear 72 drives second helical gear and rotates, and then drives whole cutter head and move forward, thereby confirms the degree of depth that blade 33 will cut.The staff can calculate the cutting output of cutter tip 3 according to the degree that feed shelter 7 rotates, and accurately judges the degree of depth of cutting.

Above embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although the utility model is specified with reference to preferred embodiment; Those of ordinary skill in the art is to be understood that; Can make amendment or be equal to replacement the technical scheme of the utility model, and not break away from the spirit and the scope of the utility model technical scheme.
