Forming a wall surface by a side of the accommodating area and extending upward from the bottom surface of the screw head, and a top surface formed by the wall surface facing the other adjacent side of the accommodating area And a cutting edge formed on the wall and the top wall, wherein the top wall is tapered by the top surface of the screw toward the rod of the fastener, so that the top wall Forming an auxiliary wall extending from the cutting edge to the other side of the adjacent accommodating area, and indirectly expanding the accommodating space of the accommodating area; so when the lock is engaged, the lock uses the auxiliary block The auxiliary matching cutting enables quick cutting into the lock compound when the lock is engaged, and the chips generated by the cutting are accommodated in the accommodating area, and are effectively pressed by the auxiliary wall to avoid excessive swarf of the swarf Externally, effectively maintaining the flatness of the lock compound after the lock, and avoiding Because the chips can not be completely accommodated crack circumstances other materials arising Further, after the locking engagement into the lock, the lock is produced with the compound tightly each engaging the locking effect, greatly enhance the tightening force after the fitting.

有關本發明之前述及其他技術內容、特點與功效,在以下配合參考圖式之較佳實施例的詳細說明中,將可清楚的明白。The above and other technical contents, features, and advantages of the present invention will become apparent from the Detailed Description of the <RTIgt;

參閱圖3至圖5,本發明之一較佳實例,包含有一桿體31,一設於該桿體31一端之螺頭32,一設於該桿體31上且相反於該螺頭31一端之鎖合部33,以及複數螺旋環設於該桿體31上之螺牙34;其中,該鎖合部34在本實施例中可為鑽尾及尖尾等態樣之設置,而以下說明係以尖尾構造為之。Referring to FIG. 3 to FIG. 5, a preferred embodiment of the present invention includes a rod body 31, a screw head 32 disposed at one end of the rod body 31, and a rod body 31 disposed on the rod body 31 opposite to the end of the screw head 31. The locking portion 33, and the plurality of helical rings 34 are disposed on the rod body 31; wherein the locking portion 34 can be a drill tail and a pointed tail in the embodiment, and the following description It is made up of a pointed tail structure.

仍續上述,該螺頭32具有一頂面321,一由該頂面321向下延伸之底面322,複數設於該底面322上之輔助塊323,以及該任二相鄰之輔助塊323間形成有一容置區324;其中,該每一輔助塊323具有一位於該容置區324之一側並由該底面322向上延伸形成之一壁面3231,一由該壁面3231朝另一相鄰之該容置區324的另一側相接形成之頂掣壁3232,以及一於該頂掣壁3232與該壁面3231相接形成之切刃3233,且該頂掣壁3232係由該頂面321朝該桿體31方向呈漸縮態樣,以便該頂掣壁3232上形成有一由該切刃3233延伸向該相鄰之容置區324的另一側之輔助壁3234,且該輔助壁3234與該頂掣壁3232相接處係呈一傾斜設置,而前述該頂掣壁3232在本實施例中係呈一弧面設計表示;另,該容置區324鑒於該等輔助塊323之結構設計因素,使得該等容置區324容置空間得以擴大。Continuing the above, the screw head 32 has a top surface 321 , a bottom surface 322 extending downward from the top surface 321 , a plurality of auxiliary blocks 323 disposed on the bottom surface 322 , and between the two adjacent auxiliary blocks 323 . An accommodating area 324 is formed; wherein each auxiliary block 323 has a side of the accommodating area 324 and extends upward from the bottom surface 322 to form a wall surface 3231, one wall 3231 facing another adjacent The top side wall 3232 of the accommodating area 324 is connected to the top wall 3232, and a cutting edge 3233 formed by the top wall 3232 and the wall surface 3231. The top wall 3232 is formed by the top surface 321 A direction of the rod body 31 is tapered, so that the top wall 3232 is formed with an auxiliary wall 3234 extending from the cutting edge 3233 to the other side of the adjacent receiving area 324, and the auxiliary wall 3234 The top wall 3232 is disposed at an inclined position, and the top wall 3232 is represented by a curved surface design in the embodiment; and the receiving area 324 is in view of the structure of the auxiliary block 323. The design factor is such that the accommodation space of the accommodating area 324 is expanded.

參閱圖3、圖4,鎖合時,先於該螺頭32施予一鎖合 扭力以連動該鎖合部33鑽鎖進入鎖合物4內,同時帶動該螺牙34對該鎖合物4產生鋒利的切削,以使該鎖固件3得以快速鎖合進入該鎖合物4內,且當該螺頭32進入時,可藉該等輔助塊323之切刃3233輔助切削,亦即於切削過程且斷裂之該鎖合物4的木纖維受到該切刃3233切削,以確實被斬斷,有效避免該木纖維纏繞產生阻力之缺失,同時鎖合時產生之切屑可受到該頂掣壁3232朝向該桿體31漸縮態樣之設計,使該切屑可順沿該頂掣壁3232至輔助壁3234向外排出,藉以大幅減少該鎖固件3鎖合之扭力,同時再藉該容置區324之容置空間的擴大設置,不但可供過多該切屑容置於其中外,同時該鎖固件3鎖合於該鎖合物4後,更能與該鎖合物4產生緊密鎖合效果,以避免該切屑無法完全容置所產生之裂材情事,且更藉由該輔助壁3234與該頂掣壁3232相接處係呈一傾斜之配合設置,使凸伸於外之該切屑於鎖合時得以受到該輔助壁3234的壓掣,進而順勢在鎖合時被壓掣於該鎖合物4內,以避免該切屑過多凸伸於外,有效維持鎖合後之該鎖合物4的平整度,使該鎖固件3鎖合後得以與該鎖合物4相互產生緊密卡掣鎖合效果,大幅提升鎖合後之緊固力等功效。Referring to FIG. 3 and FIG. 4, when the lock is engaged, a lock is applied before the screw head 32. The torque is interlocked into the lock compound 4 by interlocking the lock portion 33, and the screw 34 is driven to sharply cut the lock compound 4, so that the lock member 3 can be quickly locked into the lock compound 4 And when the screw head 32 enters, the cutting edge 3233 of the auxiliary block 323 can be used to assist the cutting, that is, the wood fiber of the lock compound 4 which is broken during the cutting process is cut by the cutting edge 3233, to be sure Being cut off, effectively avoiding the lack of resistance of the wood fiber winding, and at the same time, the chip generated during the locking can be designed to be tapered by the top wall 3232 toward the rod body 31, so that the chip can follow the top The wall 3232 and the auxiliary wall 3234 are discharged outwardly, so that the torque of the locking member 3 is greatly reduced, and at the same time, the enlarged arrangement of the accommodating space of the accommodating area 324 can not only allow the swarf to be accommodated. At the same time, the locking member 3 is locked to the lock compound 4, and is more capable of forming a tight locking effect with the lock compound 4, so as to avoid the fact that the chip cannot completely accommodate the cracked material generated, and the auxiliary device is further assisted. The wall 3234 and the top sill wall 3232 are in an inclined arrangement to make the convex The chip is pressed by the auxiliary wall 3234 when it is locked, and is then pressed into the lock compound 4 when it is locked, so as to prevent the chip from protruding excessively and effectively maintaining the lock. The flatness of the lock compound 4, after the lock 3 is locked, can produce a close snap-fit effect with the lock compound 4, and greatly improve the fastening force after the lock.

歸納前述,本發明具快速旋鎖之鎖固件,係於該螺頭之底面上設有複數輔助塊,且該任二輔助塊間形成有一容置區,因此當鎖合時,不但藉由該等輔助塊的輔助配合以產生快速切削外,且該容置區亦可供輔以切削後之切屑容 置於內,藉以與該鎖合物產生緊密鎖合,且該鎖固件鎖合後不會有任何切屑凸伸於該鎖合物外,以增加鎖合後之平整度,以使鎖合更能有效大幅提升鎖合後之緊固力,故確實能達到本發明之目的。In summary, the present invention has a quick-locking lock, which is provided with a plurality of auxiliary blocks on the bottom surface of the screw head, and an accommodating area is formed between the two auxiliary blocks, so when locked, not only by the The auxiliary fitting of the auxiliary block is used to generate the rapid cutting, and the accommodating area is also supplemented by the chipping capacity after cutting. Placed inside, thereby forming a tight fit with the lock compound, and the lock does not have any chips protruding outside the lock compound after the lock is locked, so as to increase the flatness after the lock, so that the lock is more The utility model can effectively improve the fastening force after the locking, so that the object of the invention can be achieved.

惟以上所述者,僅為說明本發明之較佳實施例而已,當不能以此限定本發明實施之範圍,即大凡依本發明申請專利範圍及發明說明書內容所作之簡單的等效變化與修飾,皆應仍屬本發明專利涵蓋之範圍內。The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent changes and modifications made in accordance with the scope of the present invention and the contents of the description of the invention.
