The foregoing existing collet can achieve the anti-reverse effect and provide better tool cooling efficiency. However, since the aforementioned cylinder loss lacks the structural design of the leading cooling water flowing forward, the cooling water can be applied to the tool without the flow path. Cannot flow forward' so it does not apply to the cooling of this type of tool. [New content] Since the existing collet cannot discharge the cooling water to the tool, it is not suitable for the tool without the flow path. To this end, the main purpose of this creation is to provide a water-conducting hole around the body of the collet, thereby guiding the cooling water and spraying it toward the tool to achieve the effect of the tool for the non-flow path and further improving the cooling and chip evacuation. effect. In order to achieve the above object, the present invention provides a water-carrying tool collet, which is provided with a collet body, wherein the collet body forms an outer end surface and an inner end surface on both end faces, and is surrounded by a concave end at the front end portion of the outer peripheral surface. The groove is further disposed with a cutter hole in the axial center, and the collet body is surrounded by the outer end surface toward the inner end surface to open a plurality of mutually spaced outer slit grooves, and the inner end surface faces the outer end surface 3 M362073 Shy fg] The inner cuts of the numbers are separated by each other. 'The plural ones are arranged in a staggered manner. The (four) system is: the number of the 'circumferential walls of the boring tool's hole is more than one. a straight groove extending in the rear direction of the 1J and having a narrow front end, the inner slit of the rear end of the collimator is communicated, and the front end is opened by the outer end surface of the collet body and located between the adjacent outer slits; 'Sr:: the outer peripheral surface of the front side and the peripheral wall IS of the cutter lost hole... the water stop plug hole 'embeds a water stop plug in each of the water stop plug holes. The 'input step' is formed at the opposite side of the peripheral wall of the cutter pin hole, and the two water outlets are respectively located between the adjacent outer slits, and are provided in the collet body Six outer slits and six inner slits, each of which is a straight extension. A concave groove bottom surface is formed in the middle of the inner surface of each of the water outlet grooves, and each groove bottom surface is a slope having a rear end shallower than the front end. Each of the outlets is a U-shaped groove having a depth of front and rear, and a shallower outlet portion is formed at the front end. When this creation is applied, it is inserted into the tapered groove of the arbor and is screwed into the groove with the nut, and then the nut is screwed into the front end of the arbor, and the tool is inserted into the tool holder hole. Then, the nut is locked to the arbor, and the clamping force of the nut and the tapered groove is pressed, and the concavity design of each inner grooving and outer grooving is made to enable the tool clamping hole to surely tighten the tool. Its positioning. When the cooling water is injected into the rear arbor, the openings formed in the circumferential surface of the collet body and the cutter hole are closed by the peripheral wall of the conical groove and the peripheral wall of the cutter. Therefore, the injected cooling water will concentrate toward the front. The effluent is sprayed forward from each of the spouts. Because of the design of the small and large ditch in front of each ditch, it is possible to make the cooling water from the cooling water sprayed from the front end of the 4 M362073 ditch to the tool and around the tool. In this way, the centralized cooling tool provides a suitable cooling hand/" for the cooling, lubrication and de-allocation without the rogue, and at the same time, the better tool is also achieved. The front end portion I which is closed by the water stop plug is provided with a water stop plug. , f close the front end opening of each outer slit 'avoid' [Embodiment] This creation is a water outlet knife ~ only + "same clip, please refer to the first preferred embodiment of the first to fourth figures, including : a collet body (10), an outer end surface (101) and an inner end surface (102) are respectively formed on both end faces of the sleeve, and the inner end surface of the outer peripheral surface is rounded and concave. The groove (11) is inserted into a tool holder hole (1 2) and the outer end surface (彳〇)) in the axial position of the plate holder (Ί U). The direction is surrounded by six equally spaced outer slits (13), and each outer cut birch ν juice grooving (13) is on the outer end surface (101), the peripheral wall of the cutter hole (12), and the collet body ( The outer peripheral surface of the 1)) is formed with an opening, and the length of each of the outer slits (13) is shorter than the length of the cylinder "1"; the inner end surface (102) is surrounded by the outer end surface (1〇1). An equally spaced inner slit (14), six inner slits (14) and six outer slits (13) are arranged in a staggered manner, and each inner slit (14) is Inner end face (彳〇2), cutter The peripheral wall of the pinhole (12) and the outer peripheral surface of the tubular body (1〇) form an opening, and the length of each inner slit (彳4) in the axial direction is shorter than the length of the collet body (彳〇); (12) Two opposite water outlets (15) are disposed between the adjacent outer slits (13). The respective water outlets (15) are straight grooves and the front end is open at the outer end surface (101). The inner surface of each water outlet groove (15) forms a concave groove bottom M362073. The surface (51) of each groove bottom surface (1 51) is a slope with a rear end shallower than the front end, whereby the 7 water outlets (15) form a front end tapered shape. The groove shape, the rear ☆ of each water outlet () and the corresponding inner slit (14), respectively, thereby connecting the coolant by the corresponding inner slit (14); corresponding to each outer slit (13) ) between the outer peripheral surface of the collet body (10) located in front of the recess (11) and the peripheral wall of the cutter clamping hole (12), respectively, a water stop plug hole, and (16) a water stop plug hole (16) There are six holes, each of which is a circular hole, and the m-fixing water plug holes (16) are respectively plugged with a water stop plug (2Q), and each water stop plug (20) Lu 4 elastic body is thereby closed Front end of the outer slit (13) The back end of the outer slit (13) is prevented from leaking water toward the front.
