一般而言，管材管件端口容易產生銳利不規則狀毛邊，若以傳統手工方式運用砂紙去除毛邊，確實相當耗費時間與人力成本。且管件端口呈傾斜狀，導致管件不易與其他連接組件穩固接合，因此手工具業者發展出一種管件修邊工具，用以整修管件端口的毛邊及不規則斜口。 Generally speaking, the ports of pipe fittings are prone to have sharp and irregular burrs. If using sandpaper to remove burrs by traditional manual methods, it is indeed time-consuming and labor-intensive. In addition, the port of the pipe fitting is inclined, which makes it difficult for the pipe fitting to be firmly joined with other connecting components. Therefore, hand tool manufacturers have developed a pipe fitting trimming tool to trim the burrs and irregular bevels of the pipe fitting port.

請參閱第1圖，圖中揭示一電動工具10連接一倒角工具20。具體而言，該電動工具10的一端具有一驅動端12，該驅動端12用以連接及驅動該倒角工具20。該倒角工具20係用以切削一工件110的末端周緣。該倒角工具20包含一本體30。一驅動桿70的一端連接該電動工具10的該驅動端12，另一端連接該本體30的一端。 Please refer to FIG. 1, which shows that an electric tool 10 is connected to a chamfering tool 20. Specifically, one end of the electric tool 10 has a driving end 12, and the driving end 12 is used for connecting and driving the chamfering tool 20. The chamfering tool 20 is used to cut the peripheral edge of the end of a workpiece 110. The chamfering tool 20 includes a body 30. One end of a driving rod 70 is connected to the driving end 12 of the electric tool 10, and the other end is connected to one end of the body 30.

請參閱第2、3圖，本實施例揭示該倒角工具20包含有該本體30、複數刀具40以及複數排屑槽50。該本體30的內部具有一空間36，該空間36的一端為一第一端32，另一端為一第二端34。該第一端32為封閉端，該第二端34為開放端，且該第二端34相對該第一端32。 Please refer to FIGS. 2 and 3, this embodiment discloses that the chamfering tool 20 includes the main body 30, a plurality of cutters 40 and a plurality of chip flutes 50. The main body 30 has a space 36 inside. One end of the space 36 is a first end 32 and the other end is a second end 34. The first end 32 is a closed end, the second end 34 is an open end, and the second end 34 is opposite to the first end 32.

該空間36的該第一端32的內徑小於該第二端34的內徑，致使該空間36概呈錐狀空間，且該空間36的內壁面自該第二端34往該第一端32傾斜延伸。各該刀具40係為線性條狀且傾斜地安裝在該空間36的內壁面，本實施例優選於三個刀具40。 The inner diameter of the first end 32 of the space 36 is smaller than the inner diameter of the second end 34, so that the space 36 is almost a cone-shaped space, and the inner wall of the space 36 extends from the second end 34 to the first end 32 extends obliquely. Each of the knives 40 is linearly strip-shaped and installed obliquely on the inner wall surface of the space 36. In this embodiment, three knives 40 are preferred.

各該排屑槽50傾斜地形成在該空間36的內壁面，且一該排屑槽50相鄰一該刀具40。該排屑槽50具有一第一槽端52以及一第二槽端54，該第一槽端52與該第二槽端54分別位在該排屑槽50的相對二端。該排屑槽50的該第一槽端52對應該本體30的該空間36的該第一端32。該排屑槽50的該第二槽端54對應該本體30的該空間36的該第二端34，且該第二槽端54的外周緣呈弧形狀。進一步，該排屑槽50由該本體30的該第一端32往該本體30的該第二端34傾斜，且該 第二槽端54的內徑大於該第一槽端52的內徑。進一步，該第二槽端54延伸至該空間36的該第二端34的端面。值得注意的是，該排屑槽50的底部為一封閉面56。 Each of the chip flutes 50 is obliquely formed on the inner wall surface of the space 36, and one chip flute 50 is adjacent to the tool 40. The chip groove 50 has a first groove end 52 and a second groove end 54. The first groove end 52 and the second groove end 54 are respectively located at two opposite ends of the chip groove 50. The first groove end 52 of the chip flute 50 corresponds to the first end 32 of the space 36 of the body 30. The second groove end 54 of the chip flute 50 corresponds to the second end 34 of the space 36 of the body 30, and the outer periphery of the second groove end 54 is arc-shaped. Further, the chip flute 50 is inclined from the first end 32 of the main body 30 to the second end 34 of the main body 30, and the The inner diameter of the second groove end 54 is larger than the inner diameter of the first groove end 52. Further, the second groove end 54 extends to the end surface of the second end 34 of the space 36. It is worth noting that the bottom of the chip flute 50 is a closed surface 56.

請參閱第4圖，值得注意的是，由於各該刀具40係傾斜地平均安裝在該空間36的內壁面，且該空間36的該第一端32小於該第二端34，所以各該刀具40朝向該空間36內部的側面(刃面)可構成錐狀空間。 Please refer to Figure 4, it is worth noting that since each of the cutters 40 is installed on the inner wall surface of the space 36 obliquely and evenly, and the first end 32 of the space 36 is smaller than the second end 34, each of the cutters 40 The side surface (blade surface) facing the inside of the space 36 may constitute a tapered space.

請參閱第5圖，根據以上組合形式，本實施例的使用狀態係該本體30受該電動工具10的該驅動端12驅動而轉動，且該刀具40的刃面可以切削該工件110的端部外周緣，此時，該刀具40於切削過程中會產生切屑41。值得注意的是，由於該排屑槽50的延伸方向往該本體30的該第二端34傾斜，使得該切屑41能夠藉由該排屑槽50順利落出。根據以上說明，該電動工具10帶動該刀具40切削該工件110的過程中所產生的切屑可藉由該排屑槽50順利排出。特別是，由於該排屑槽50的底部為封閉面(圖未示)，故該切屑41不會穿出該排屑槽50的底部進而噴濺傷及使用者。 Referring to Figure 5, according to the above combination, the use state of this embodiment is that the main body 30 is driven to rotate by the driving end 12 of the electric tool 10, and the blade surface of the tool 40 can cut the end of the workpiece 110 The outer periphery, at this time, the tool 40 generates chips 41 during the cutting process. It is worth noting that since the extending direction of the chip flute 50 is inclined toward the second end 34 of the body 30, the chips 41 can be smoothly dropped out through the chip flute 50. According to the above description, the chips generated in the process of driving the tool 40 to cut the workpiece 110 by the electric tool 10 can be smoothly discharged through the chip flute 50. In particular, since the bottom of the chip flute 50 is a closed surface (not shown in the figure), the chips 41 will not penetrate the bottom of the chip flute 50 and splash and hurt the user.

請參閱第6圖，值得注意的是，本實施例更包含一墊片60。該驅動桿70的一端穿過該墊片60並鎖接於該本體30的一端外部，且該墊片60位在該本體30的一端外部。如此一來，該電動工具10的該驅動端12驅動該驅動桿70與該本體30的過程中，雖然該驅動桿70會隨著該電動工具10的作動而產生朝向該本體30位移的趨勢，但是該驅動桿70的位移方向受到該墊片60的阻擋，故可以降低該驅動桿70過度伸入該本體30內部的機率，進而使得該驅動桿70與該本體30呈現穩固結合以及能夠穩定傳遞輸出扭力的效果。 Please refer to FIG. 6. It is worth noting that this embodiment further includes a gasket 60. One end of the driving rod 70 passes through the washer 60 and is locked to the outside of one end of the main body 30, and the washer 60 is located outside of one end of the main body 30. In this way, when the drive end 12 of the electric tool 10 drives the drive rod 70 and the body 30, although the drive rod 70 tends to move toward the body 30 along with the action of the power tool 10, However, the displacement direction of the driving rod 70 is blocked by the spacer 60, so that the probability of the driving rod 70 over-extending into the body 30 can be reduced, thereby making the driving rod 70 and the body 30 present a stable combination and stable transmission. The effect of output torque.

請參閱第7、8圖，本發明其他的實施例形式係一種具有較大體積的倒角工具21。該倒角工具21包含有一本體80、複數刀座82、複數刀具86以及 複數排屑槽88。其中該本體80的內部具有一空間84。該空間84具有封閉的一第一端840以及開放的一第二端842。該空間84具有大的內徑，故可供更多數量的該刀具86容置及安裝。 Please refer to Figures 7 and 8, another embodiment of the present invention is a chamfering tool 21 with a relatively large volume. The chamfering tool 21 includes a body 80, a plurality of tool holders 82, a plurality of tools 86, and Multiple chip flutes 88. There is a space 84 inside the main body 80. The space 84 has a closed first end 840 and an open second end 842. The space 84 has a large inner diameter, so a larger number of the cutters 86 can be accommodated and installed.

複數刀座82係形成在該本體80的該空間84的內壁面。該刀座82的一端相鄰該空間84的該第一端840，該刀座82的另一端相鄰該空間的該第二端842的端面。一安裝面83形成在該刀座84的相對二端之間，該刀具86係安裝在該安裝面83。 A plurality of tool holders 82 are formed on the inner wall surface of the space 84 of the main body 80.

This embodiment is the same as the previous embodiment, including a body 90 with a space 94, a plurality of tool holders 96 protrudingly form the inner wall surface of the space 94, and a tool 98 and a chip groove 97 are formed in the tool. Seat 96.

請參閱第11、12圖，本實施例與前一實施例(第8、9圖所示)的差異在於：本實施例包含複數補強肋92。該補強肋92係凸出且傾斜地形成在該本體90的該空間94，且該補強肋92位在二該刀座96之間，即該補強肋92亦位在二該刀具98之間。此外，該補強肋92的形狀可以概呈三角形。由於該空間94具有較大的內徑，故該補強肋92可用以增強該本體90的結構強度。此外，藉由該補強肋92，可使該補強肋92與該刀座96之間具有較小的間距，使被加工的工件不易落入該間距內。 Referring to FIGS. 11 and 12, the difference between this embodiment and the previous embodiment (shown in FIGS. 8 and 9) is that this embodiment includes a plurality of reinforcing ribs 92. The reinforcing rib 92 is protrudingly and obliquely formed in the space 94 of the main body 90, and the reinforcing rib 92 is located between the two tool seats 96, that is, the reinforcing rib 92 is also located between the two tools 98. In addition, the shape of the reinforcing rib 92 may be roughly triangular. Since the space 94 has a relatively large inner diameter, the reinforcing rib 92 can be used to enhance the structural strength of the body 90. In addition, with the reinforcing rib 92, a small distance between the reinforcing rib 92 and the tool holder 96 can be made, so that the workpiece to be processed does not easily fall into the distance.
