【発明の属する技術分野】
本発明は一種のスパナに係り、特に一種の、防滑及び角潰れ防止のスパナに関する。
【0002】
【従来の技術】
伝統的な産業中、特に手持ち工具は大量の販売市場を有し、それは品質、実用性及び良好な操作性などの因子がいずれも市場での優勢を占有することにより、市場を確保できる。このため手持ち工具は製造の方式及び過程が直接コストと生産速度と密接に関係し、また、現在の手持ち工具の最も重要な競争力となる。
【0003】
図1は周知のオープンエンドスパナ10であり、それはハンドル11を具え、該ハンドル11の一端より二つの、ほぼ等長の第1顎12、第2顎13が延伸され、該第1顎12、第2顎13間に喉孔14が形成され、該喉孔14が6個の側辺と6個の角を具えた六角形固定部品20に套設され、第1顎12、第2顎13の内側面にそれぞれ平行な当接辺121、131が設けられ、相互に所定の距離離間し、そのうち、回す操作を行う時、当接辺121、131はそれぞれ固定部品20の第1側辺21、第2側辺22に当接し、スパナ10が力を受けて固定部品20を駆動し、固定部品20が確実にスパナ10により回される。しかし、当接辺121、131は平坦面であるため、回す時に空回りの状況を発生しやすく、喉孔14が摩擦現象を発生し、摩損して角を潰し、また回す時に、当接辺121、131に対応する第2、第3角24、25も、当接辺121、131と摩擦を発生し、角が丸くなり、並びに該オープンエンドスパナ10の喉孔14は内凹円弧状を呈し、固定部品20の第3、第4側辺26、27位置に当接せず、回す過程で、比較的高いトルク表現を提供できず、このためオープンエンドスパナ10には改良の必要があった。
【0004】
図2は上述の欠点を解決した別の周知のオープンエンドスパナ30構造であり、そのハンドル31の一端の第1、第2顎32、33の内側面に、それぞれ噛合歯321、331が設けられ、回す過程で、固定部品20の第1側辺21及び第2側辺22に噛みつき、それが空回り状況を発生しないようにしている。これは防滑の機能を有するが、固定部品20の第1角23が喉孔34と摩擦の現象を発生しやすく、及び固定部品20の第2、第3角24、25と第1、第2顎32、33内側面が回すうちに摩擦の状況を発生し、これは未だに改善されておらず、且つオープンエンドスパナ10の喉孔14が内凹円弧状を呈するため、固定部品20の第3、第4側辺位置に当接できず、比較的高いトルク表現を提供することはできず、当然、改良の必要を有していた。

BACKGROUND OF THE INVENTION
The present invention relates to a kind of spanner, and more particularly, to a kind of spanner for preventing slippage and preventing collapse of corners.
[0002]
[Prior art]
In traditional industries, especially hand-held tools have a large sales market, which can secure the market because factors such as quality, practicality and good operability all dominate the market. For this reason, the method and process of manufacturing a hand-held tool is closely related to the direct cost and production speed, and is the most important competitiveness of current hand-held tools.
[0003]
FIG. 1 shows a known open-end spanner 10 which includes a handle 11, from which one of the first jaw 12 and the second jaw 13 are extended from one end of the handle 11. A throat hole 14 is formed between the second jaws 13, and the throat hole 14 is provided on a hexagonal fixing part 20 having six sides and six corners, and the first jaw 12 and the second jaw 13. Abutting sides 121 and 131 that are parallel to the inner surface of each of the fixing parts 20 are provided, spaced apart from each other by a predetermined distance. The spanner 10 abuts against the second side 22 and receives the force to drive the fixed component 20, so that the fixed component 20 is reliably rotated by the spanner 10. However, since the contact sides 121 and 131 are flat surfaces, it is easy to generate an idle state when turning, and the throat 14 generates a friction phenomenon, wears and crushes corners, and when turned, the contact side 121 is turned on. , 131 also generate friction with the contact sides 121, 131, the corners become round, and the throat hole 14 of the open-end spanner 10 has an indented arc shape. The third and fourth sides 26 and 27 of the fixed component 20 do not come into contact with each other, and a relatively high torque expression cannot be provided in the process of turning. Therefore, the open-end spanner 10 needs to be improved. .
[0004]
FIG. 2 shows another well-known open-end spanner 30 structure that solves the above-mentioned drawbacks, and meshing teeth 321 and 331 are provided on the inner surfaces of the first and second jaws 32 and 33 at one end of the handle 31, respectively. In the turning process, the first side edge 21 and the second side edge 22 of the fixed component 20 are engaged with each other so that the idle state does not occur. This has a function of preventing slipping, but the first corner 23 of the fixing part 20 is liable to generate a friction phenomenon with the throat hole 34, and the second and third corners 24, 25 of the fixing part 20 and the first and second As the inner surfaces of the jaws 32 and 33 are rotated, a frictional state is generated, which has not been improved yet, and the throat hole 14 of the open-end spanner 10 has an inner concave arc shape. In this case, it was impossible to contact the position of the fourth side, and a relatively high torque expression could not be provided, and naturally there was a need for improvement.
