In addition, there is a cooling type knife handle that has a channel directly inside the knife handle. When processing, the cooling liquid can be sprayed from the tool holder for cooling and lubrication. The conventional cooling tool holder structure is attached to the bottom of the tool holder with a sleeve nut attached to the tool. The sleeve nut has One is located in the center hole of the cutter, and a number of 15 water supply joints are provided around the center hole; each water supply joint is used to communicate with the channel inside the handle, so that the coolant can be sprayed from the inside of the handle through each water supply joint and directly injected into Tools and workpieces. However, when the user uses the above-mentioned cooled knife handle for processing, if he encounters tool damage, or needs to change tools of different sizes, the entire set of 20 sets of socket nuts must be removed from the knife handle, and then replaced with different center holes The size of the socket nut not only increases the trouble in operation, but also must prepare multiple sets of socket nuts for replacement, which increases the production cost.

12底端外部，使得刀具30穿設於套接螺帽20之中心孔34。 各該給水接頭22係包含有一套管42、一滾珠44以及 一彈簧46;各套管42底端具有一環狀擋垣48,滾珠44具 有一貫孔50，係設於套管42中且抵頂於擋垣48内側，而 5 彈簧46係設於套管42内；各給水接頭22以套管42塞固 且緊配合地埋設於套接螺帽20之各接孔38中，使得滾珠 44與彈簧46 —起限制於接孔38内，彈簧46 —端抵觸於 接孔38内面，另一端則推抵滾珠44抵接於擋垣48上；如 圖三所示，結合後的套管42前端與套接螺帽20底面平齊， 10 且貫孔50係經由通孔25與彈性筒夾14之剖溝32以及刀 桿12之引溝28連通於刀桿12之軸孔26 ;使用者可利用 一輔助工具穿插入滾珠44的貫孔50中，藉以調整滾珠44 轉向，進而改變貫孔50之方向。 該定位環24係呈圓板狀，其外徑與套接螺帽20之中 15 心孔34孔徑相同，定位環24具一内孔35，内孔35之孔 壁嵌設有一止漏環52 ;該定位環24係設於套接螺帽20之 中心孔34内，使得刀具30係穿設於内孔35，止漏環52 則緊密環設於刀具30周圍，而由於定位環24之外周壁擠 壓於止漏環36，形成定位環24緊固於套接螺帽20上。 20 以上即為本創作之各構件及其相關聯位置之說明，如 圖一所示，該滾柱軸承16係預先結合於鎖緊螺帽18内部， 且如圖二所示，當刀把10結合刀具30時，冷卻液可自刀 样12的軸孔26頂端處注入到刀桿12内部，而受到刀具 30與止漏環36等的阻隔所致，冷卻液將循著筒夾14的剖 M25508812 is outside the bottom end, so that the cutter 30 passes through the central hole 34 of the socket nut 20. Each of the water supply joints 22 includes a sleeve 42, a ball 44 and a spring 46; the bottom end of each sleeve 42 has an annular stop 48, and the ball 44 has a through hole 50, which is arranged in the sleeve 42 and abuts against it. Abutting on the inside of the retaining wall 48, and the 5 springs 46 are set in the sleeve 42; each water supply joint 22 is plugged with the sleeve 42 and buried tightly in each connection hole 38 of the socket nut 20, so that the ball 44 It is confined with the spring 46 in the connection hole 38. One end of the spring 46 abuts against the inner surface of the connection hole 38, and the other end pushes the ball 44 against the retaining wall 48. As shown in FIG. The front end is flush with the bottom surface of the socket nut 20, 10 and the through hole 50 is connected to the shaft hole 26 of the tool bar 12 through the through hole 25 and the groove 32 of the elastic collet 14 and the guide groove 28 of the tool bar 12; the user; An auxiliary tool can be inserted into the through-hole 50 of the ball 44 to adjust the turning direction of the ball 44 to change the direction of the through-hole 50. The positioning ring 24 is in the shape of a circular plate, and its outer diameter is the same as the diameter of the 15 center hole 34 in the socket nut 20. The positioning ring 24 has an inner hole 35, and a leak ring 52 is embedded in the wall of the inner hole 35. The positioning ring 24 is provided in the center hole 34 of the socket nut 20, so that the cutter 30 is threaded through the inner hole 35, and the leak-proof ring 52 is tightly disposed around the cutter 30. The wall is pressed against the leak-proof ring 36 to form a positioning ring 24 fastened to the socket nut 20. The above 20 is the description of the components of the creation and their associated positions. As shown in Figure 1, the roller bearing 16 is pre-combined inside the lock nut 18, and as shown in Figure 2, when the tool holder 10 is combined At the time of the cutter 30, the coolant can be injected into the arbor 12 from the top of the shaft hole 26 of the cutter 12 and is blocked by the cutter 30 and the leak ring 36. The coolant will follow the section M255088 of the collet 14
溝32、刀桿12内部的引溝28而往各給水接頭22方向流 動，並通過通孔40進入套管42内，再自滾珠44之貫孔 50噴出，所噴出的冷卻潤滑液將直接對刀具30及被加工 物部位（圖中未示）產生冷卻與潤滑效果。 5 當使用者欲更換另一不同直徑的刀具時，係僅需換裝 適用於新刀具的筒夾，以及内孔尺寸配合新刀具直徑的定 位環即可；藉此，本創作即可在不更換刀桿、鎖緊螺帽以 及套接螺帽之前提下，使用各種不同尺寸之刀具，以達到 降低使用成本之目的。 10 另外，本創作亦可視使用上之需要，將給水接頭以其 他不同形式取代；請參閱第四圖所示，係為本創作之第二 較佳實施例，其與第一實施例之主要構件大致相同，特點 在於：刀把60之給水接頭61的套管62底端係凸出於套接 螺帽63之底面，藉以方便使用者更換給水接頭61 ;或是 15 如第五圖所示，為本創作之第三較佳實施例，當使用者不 須導通冷卻液或僅需由部份接孔噴出冷卻液時，可將套接 螺帽71之接孔72内改設一塞設件73，用以封閉刀把70 内之冷卻液流道，使冷卻液經由一具中心通孔之刀具喷 出，藉以冷卻刀具與加工物。 20 -8- M255088The groove 32 and the guide groove 28 inside the shank 12 flow in the direction of the respective water supply joints 22, and enter the sleeve 42 through the through hole 40, and then spray out from the through hole 50 of the ball 44. The sprayed cooling lubricant will directly The tool 30 and the workpiece (not shown) produce cooling and lubrication effects. 5 When the user wants to change another tool with a different diameter, the user only needs to replace the collet suitable for the new tool, and the positioning ring with the new hole diameter to match the new tool diameter; Before replacing the tool bar, lock nut and socket nut, use a variety of different size tools to reduce the cost of use. 10 In addition, this creation can also replace the water supply connector in other different forms according to the needs of use; please refer to the fourth figure, which is the second preferred embodiment of this creation, which is the main component of the first embodiment It is almost the same, the characteristic is that the bottom end of the sleeve 62 of the water supply joint 61 of the handle 60 is protruded from the bottom surface of the socket nut 63, so that the user can replace the water supply joint 61; or 15 as shown in the fifth figure, In the third preferred embodiment of the present invention, when the user does not need to conduct the cooling liquid or only needs to spray the cooling liquid from a part of the connecting holes, a plugging member 73 may be provided in the connecting hole 72 of the socket nut 71. It is used to close the cooling liquid flow path in the knife handle 70, so that the cooling liquid is sprayed through a tool with a central through hole, thereby cooling the tool and the processed object. 20 -8- M255088
