Description of the new type: [Technical field to which the new type belongs] This creation is about a hand-held one-way rotating tool, especially a tool that can rotate the tool in one direction, holding the hand on the hand piece to rotate the force in the positive direction. The cutting operation directly rotates the wrist in the reverse direction. The overall structure is small and can be carried easily. It is extremely convenient to operate and use. [Previous technology] General pipe fittings (4), such as copper pipes of air conditioners, are used to repair the burrs or chamfers of pipe fittings (4), mainly using a hand-held fixed-rotation processing tool (6), such as the seventh As shown in Fig. 8, the tool (6) is provided with a cavity (61), and the cavity (61) is provided with a cutter (62). When the pipe fitting (4) is to be deburred or chamfered, Set the f piece (4) in the recess (M) of the tool (6), so that the cutting end of the cutter (62) abuts against the pipe member ⑷, and then hold it with the hand outside the tool ，, and apply ^ square 疋"Turn force 畺", and when the mother uses the wrist to force an angle to perform cutting, she must first release the grip of the hand, and turn the hand and the wrist in an opposite direction, and then hold it on the tool 人 again. Applying force, turning force intermittently, can not be cut continuously, and the operation is not easy, and this tool (6) can only be used for the trimming or chamfering of the pipe fitting ⑷, if it is necessary to chamfer the round hole ⑸ of the long workpiece, This kind of tool is not _, and there is another-a kind of electric rotary electric safety gear, although this kind of electric tool can easily rewrite the ⑸ or round hole ⑸ marriage or remove the burr left in the round hole 或 or Cutting, but the power tool has a large accumulation and is inconvenient to carry, and the tool must use a power source. If the guard piece to be processed is too small or the processing slot is too large, the M282818 n cannot be processed smoothly. 1 Limited by the use occasion; use is extremely convenient: 【 New W] The main purpose of this creation is to provide a hand-held one-way rotary cutter, which is small in size and can be carried easily. The structure of this creation is characterized by: including a hand piece, with an assembly groove '· one-way rotation seat, fixed in the above assembly groove, with a group of connection holes that can be rotated in one direction, a cutter, with -read End-to-group connection end, the group connection end is assembled in the above-mentioned connection hole; further, a positioning pin is provided on the hand piece, and the cutter is provided with a clamping slot. [Embodiment] As shown in the first and second figures, the creation mainly includes: a hand piece ⑴ 'the hand piece 设有 is provided with a-slot ⑴), and has an external end of the slot (Π) Group strike groove (I?); A one-way rotation seat ⑵ 'is fixed in the above assembly groove ，, and has: a group of connection holes 可 which can rotate in one direction;' The one-way rotation seat ⑵ can be provided It is a one-way bearing or a ratchet; a cutter ⑶, which has a cutting end ⑶) and a set of joints (32), the set of joints (32) are assembled in the assembly holes of the one-way rotary seat ⑵ Ii) The 'tool' (3) is a cone taper or a cone drill, as shown in the first and third figures. —As shown in the first, second, fourth, and fifth figures, the one-way rotating seat is fixed to the handpiece, and the slot is installed (⑵ towel, the one-way Wei cake ⑵ can be assembled in the assembly hole). The cutter ⑶ of the towel rotates in one direction, and the user inserts the assembly end (32) of the cutter M282818 (3) (such as a tapered knife or a tapered drill bit) into the assembly of the one-way rotary seat (2) In the hole (21), the one-way rotation seat (2) can only be used for the tool (3) to rotate in the opposite direction. When the user wants to chamfer the pipe (4) or the round hole (5), 41), (51) or when removing the chips remaining in the circular hole ⑸, the user holds the hand piece (1) with his hand, and rotates the hand piece (1) in the forward direction with the force of his wrist. Positioning of the rotary seat (2), so that it can rotate forward with the linkage of the hand piece (1), and the cutting end of the tool (3) is abutted against the end of the pipe (4) or the round hole (5) Inside and rotating to produce cutting effect, and every time the wrist is rotated by an angle to perform cutting, the hand and wrist must be reversed by an angle to force again, and it is set in the handpiece (丨). One-way rotation seat ⑵ Make the tool ⑶ rotate in the reverse direction, so the user does not need to relax when holding on the handle ⑴, just reverse it, you can straighten the user's hand and wrist, so repeat the above action, you can Easily chamfer (41), (51) the end of the official part (4) or the inside of the round hole (5), and the cutter (3) can replace the scaly scraper or cone drill according to the required processing method 'Just pull the tool ⑶ directly from the hand piece ，, and then insert the required processing tool ⑶ on the hand piece (1), it is very convenient to replace and use, the whole product is small, and it can be portable. It is suitable for chamfering round holes and cleaning internal debris in various processing parts, and the operation is extremely simple and convenient. In addition, please refer to the sixth figure, which is another example of this creation, and the fixing piece (13) can be set on the hand piece, and the card slot (3A) | 33) '疋 位 tip (13) Snap into the slot (33), so that the cutter can be positioned 7 M282818 in the slot (1M) of the hand piece (1A), and it will not come out in the rain; And Tong Jimu sees things touching things: The first one, 'Reliance is already in compliance with the _ turn requirements, the new lack of application addiction, I ask for an early conclusion' and give the right to turn, and I feel very harsh.
