The portion 72 can be rotated in a single direction with respect to the body 2. By allowing the user to continuously hold the grip portion 72, the user can easily work without causing the positioning portion 63 of the circular knife to be off-center or the tool is skewed. The figure 7 is drawn or cut out by the user; in addition, the holding unit 7 is inserted through a bolt member 74 and locked to the circular hole 711 of the sliding portion 71 and the long hole at the innermost side of the body 2 21, the user can lock the holding unit 7 at different positions on the elongated hole 21, or lock on the long holes 21, thereby allowing the user to hold the holding unit according to the optimum position. 7 is adjusted to a more convenient position and then locked, and the fun of use is further improved. Since the working unit 7 is formed on the body 2, the user does not adjust the position of the grip unit 7 to affect the work. The operation of unit 4.

In particular, the applicant has referred to FIG. 7 in conjunction with FIG. 3, which is a partial cross-sectional view of the assembled extension member 3 in combination with the body 2, wherein the first engaging portion 23 of the body 2 Forming a rib 231 thereon, a protrusion 232 is formed at the end of the rib 231, and the extension 3 is A card slot 332 is formed in the latching portion 33. A recess 333 is formed in the end of the latching slot 332. When the first latching portion 33 is engaged with the first latching portion 23, the latching rib 231 is accommodated in the latching portion 33. The card slot 332 is located in the recess 333, thereby achieving stable card insertion between the extension member 3 and the body 2; further, in order to enable the present invention to form a plurality of extensions 3 The structure of the first engaging portion 23 is the same as that of the second engaging portion 34, and the structure of the first engaging portion 33 is substantially the same as that of the second engaging portion 25 formed on the end cover 24. .

It is worth mentioning that, as shown in FIG. 8 and FIG. 9 together with FIG. 3, the present invention can selectively assemble at least one extension 3 on the body 2 according to the actual needs of the user, and the The positioning unit 6 is freely slidable through the sliding slot 611 of the slider 61 to the rib 22 on the body 2 and the rib 32 on the extension member 3, as shown in FIG. A schematic diagram when the extension member 3 is not assembled, wherein the end cover 24 is directly fitted to the body 2, and the movement of the positioning unit 6 is restricted by the blocking rib 241, so that the positioning unit 6 is held on the body. In addition, please refer to FIG. 9 , which is a schematic view of the creation of the plurality of extensions 3 , wherein the nut 352 of the extension 3 is disposed on the front end of the body 2 and the extension 3 . The positioning unit 6 is slidably disposed on the body 2 and the extension member 3 by the sliding slot 611 at the top and bottom of the slider 61. Therefore, the positioning unit 6 is not received by the nut 352 of the extension member 3. The effect can be free to slide on the body 2 and the extension member 3; in addition, the creation is also determined A needle cover 65 is disposed on the position portion 63 to prevent the user from being accidentally touched by the positioning portion 63, and the needle cover 65 can be sleeved on the hand portion 64 to be fixed and prevented from being lost.

It is known from the above that this creation is indeed in line with "industry availability", "novelty" and "progressiveness". It proposes a new type of patent application according to law, and prays for review and early grant of patents.
