When in use, the second figure will be referred to as [2], and has a base 81 and a second roller 83. The energy storage: 'One end is fixed to the base 81, and the tube to be cut 90 is loaded, 5 200924883 will be pushed up and the energy storage portion 82 is deformed and the cutter 82i is slightly retracted 'force the cutter 821 to have - The force of the infeed, when the automatic infeed cutting device 8 is rotated relative to the pipe to be cut 90, the paste will gradually become: the pipe to be cut 90 is fed and finally cut. The shortcomings are still: * good grip, only suitable (four) size of the pipe to be cut 9 〇 (too big or too small can not be used), must be rotated above the degree of elimination and exercise. ❹ ❹ [3] Referring to the third figure, this is a conventional rotary tube cutting device, which includes a body 6 - a handle 62, a feed screw 63, a rotary unit 64 and a set of cutters 65 . The set of cutters 65 is disposed on the rotating unit 64. The rotating unit 64 is rotatable in the body 61. When the rotating unit is rotated to a certain position, the rotation of the feeding knob 63 can be achieved. The purpose of feeding or retracting, but not automatic feeding. [4] As shown in the fourth and fifth figures, this is a conventional shank type pipe cutting device 95, which includes a rotating body 95A and a pair of outer casings 95B. The rotating body 95A has all the knives 951 and two rollers 952. One feed knob 953. The pair of outer casings 95B are formed by combining two sheets 954. This rotating body 95A is unidirectionally rotatable, but since the rotating body 95A and the feed knob 953 are convex, it is easy to get stuck to the obstacle next to it. However, the 'work of official removal' can take place in many places, and the following practical cases are used to illustrate: 200924883 ω is cut under the sink of the kitchen sink. For example, the faucet of the sixth and the first figure will be connected - cold water pipe 97 and - hot water pipe Γ ^ under the sink - drain pipe ". If you use the traditional knives 70 ==== knife cutting device 8Q to cut the pipe, the water red person must lie down and pull the hand to the cold water pipe 97 below the sink or the position of the hot water pipe (10). Homework (see Figure 6), its main disadvantages are that it is not easy to grasp, can not automatically enter the boring tool (referring to the mini cutter 7 〇), must rotate more than 360 degrees (refers to your knife 7 〇 and automatic feed cutting tube Device 8G) and operation _f force working phase posture is poor, easy to back pain and arm pain. However, if the above-mentioned rotary pipe cutting device or the shank pipe cutting device 95 is used for the pipe cutting operation, the rotating pipe cutting device 60 or the stalking device may be killed when rotated due to insufficient space. It is not easy and the problem of hitting the wall 96 or the adjacent pipe fittings, as shown in the seventh figure, is not working at all. In addition, if it is necessary to cut the tube portion 9Π or 981 (as shown in the sixth figure) located in the concave space between the wall (4) and the water tank, it is impossible to apply -I. 〇' ~ [b] under the paving equipment The complex pipeline reading, as shown in the figure, if there is a four pipeline 93A under the shop (not shown), coffee, coffee and coffee and U-shaped obstacle 93E (for example, a wall) In the meantime, I hope to cut the pipe inside the pipeline. The traditional mini cutter 7 进 旋 73 73 may encounter adjacent pipelines 93B, 93D or u-type obstacles. If the rotary pipe cutting device 60' is used to be engaged on the pipe 93C, the handle portion 62 will be stuck or the 93d will be unable to be inserted due to the bite gap and the shank rib 7 200924883; With the traditional automatic feeding and cutting tube s device 80, there will be difficulty in grasping or the arm is not enough D. If the shank tube cutting device 95 is changed, the protruding infeed 3 and the rotating body 95 are working. It will be an easy object to rotate. (4) It is therefore necessary to study rhyme techniques and bribe the above shortcomings.

The above is the first embodiment of the present invention. ▲ In addition, referring to FIG. 18, this is a second embodiment of the present invention, wherein the 忒C-shaped shell portion 10 has a connecting recess 14 and an extended urging grip, and the connecting recess 14 is used. The extension force applying grip 4 is set on the c-shaped shell portion 1〇, so that after the extension of the force applying grip 4G, the force applying arm is longer, the operation is more labor-saving, and the loosening is performed. Cut the tubular workpiece 5〇. More importantly, it is assumed that there are two adjacent obstacles 51 next to the tubular work 5G, as shown in the fourteenth and fifteenth figures, so that the work allowable angle θι (as shown in Fig. 16) is rather limited' For example, only (10) degrees. At this time, the user first grasps the extended urging grip 4 上 on the C-shaped shell portion 10, and rotates a working angle to a second position P2 by a first position ρι (as shown in FIG. 16). (As shown in Fig. 17) 'At this time, since each one-way stopper assembly 3 is stuck to the one-way ratchet portion 131, the rotary tube cutting unit 2 is synchronized with the c-shell portion 1 Turn, 11 200924883 The action of cutting can be performed. Then, the second position p2 is returned to the first position P1. At this time, each one-way limiting component 30 will slide over the one-way ratchet portion 131, so that only the c-shaped shell portion 1〇 rotates. Come back, the rotary tube cutting unit 20 does not move. Thereafter, the first position pi is again rotated to the second position μ, and the next infeed cutting is performed, continuously repeated, and finally cut. Therefore, even if there is an obstacle 51, the work difference (10) required for the present invention can be recorded. In other words, the present invention can be continuously operated in a narrow and obstacle-free space. Further, 'as shown in the nineteenth embodiment, 'this is a third embodiment of the present invention, wherein the connection recess 14 is preferably a square recess' having four inner surfaces 14 each having an inner surface 141 The positioning recess 142 is provided with a square protrusion 41 corresponding to the recess 14 and having four outer surfaces 411. One of the outer surfaces 411 is provided with a positioning elastic protrusion 412. It can be temporarily fixed by being inserted into the corresponding positioning recess 142. Of course, the extended force applying handle 40 can be an L-shaped structure (as in the fourth embodiment shown in FIG. 20) or a two-section structure (as in the fifth embodiment shown in FIG. 11). In the fourth embodiment, the extended force applying grip 4〇 may be separated from the c-shaped shell portion 10, and the extended force applying grip 40 may be after the present invention has been engaged with the line 93C to be cut. Inserted into the connecting recess 14 and snap-fitted into one body 'to facilitate the subsequent pipe cutting operation', in other words, even if there are three lines, 93B, 93C and a shackle type 93E (for example, a wall), the present invention can still drill through the gap. After the pipe 93C is first engaged, the extended force grip 4 连接 is connected to achieve the operation mode that the conventional 12 200924883 device cannot reach. Further, in the case where some deep holes or hands are not easily stretched, the tube portion 971 (or 981) of the sixth figure can be solved by the fifth embodiment of the present invention. As shown in FIG. 21, the extended force applying handle 40 is a two-section type having a first rod portion 40A, a second rod portion 40B and a pivot portion 40C, which can be in a deep hole or a hand. It is not easy to reach and 'make first', then connect the extended force-applying handle 4〇, and then reciprocally rotate an angle with the tube part 971 to be cut as a rotation axis to complete another ❹ ❹ Lying thin. That is, the two-section design can be changed to any angle of insertion to improve the efficacy and range of the obstacles. Not to mention, the advantages and effects of the present invention can be summarized as follows: [1] It can be continuously operated in a narrow φ and obstacle (4). As long as there is an angle between the obstacles, the side can be- The reciprocating action in small angles is suitable for moving the knife in the vicinity of obstacles and existing pipelines. It is better to use the L-shaped or two-section extended force grip. ϋ 敎 敎 便于 便于Hand operation. Because the C-shaped shell part of the invention is pure in the user's family, when the axis is fixed, the force is rotated to the circumference of the shaft. When there is an obstacle, it can be used at a small angle (ie, within the working range). Mjian's operation angle is improved, which in turn improves the efficiency of the pipe cutting operation. 顺 [3] The rotary pipe cutting unit of the tilting size can be flexibly replaced. The C type 13 200924883 of the present invention adopts the size of the 疋 但The rotary pipe can be loaded into different cutting pipes as early as, for example, a three-dip tube unit, the outer surface of which has the same size but the working distance of the cutter is 12mm to 18, respectively, to 24 wake and 24 to 3 Three models (referred to as "small size", "medium size", "large size") These two models can be loaded with people, so they can be used for lions. They can be used to change the rotary tube unit of different sizes. (4) Can be matched with - extended force grip in the narrower When the extension biasing grip is fixed to the c-shaped shell portion on the connecting recess, the force arm is lengthened, and the operation is more labor-saving. The above is only difficult to implement, and the correction is correct. Any simple modifications and variations of the embodiments of the invention will be made without departing from the spirit and scope of the invention. From the above detailed description, it will be apparent to those skilled in the art that the invention can be '爰Proposed invention patent application. ❹ 14 200924883 [Simple description of the diagram] The first picture is a schematic diagram of a traditional mini cutter.
