New description: [New technical field] This creation is related to the ratchet wrench. In more detail, especially the type can effectively simplify the construction' reduce manufacturing and assembly costs, and turn the operation Pneumatic/electric ratchet wrench structure for stability and smoothness. - [Prior Art] Air-pneumatic ratchet wrenches, which are commonly known in the art, such as the patents No. 248718 and No. 41G716 of the Chinese Patent No. 248,718 and No. 41G716, have been disclosed as having a handle - a pneumatic drive mechanism is mounted inside the handle. A ratchet seat is mounted on the front end, and a crankshaft is axially disposed at a rear end of the ratchet seat for interlocking a ratchet wheel for reciprocating left and right, and a ratchet stone is mounted on the ratchet seat to occupy a rehearsal. The rotation of the ratchet group is driven to rotate, and the rotation (4) is used to control the forward rotation and the reverse rotation of the switching ratchet station; however, the ratchet seat and the ratchet station of the air ratchet wrench are both fixed angle design, and therefore cannot follow the operating environment or The limitation of the work, the adjustment of the suitable turning operation angle, resulting in limited functionality, according to which the manufacturer sets a pivot point on the ratchet seat and improves the crankshaft of the drive mechanism and the ratchet set. The ratchet seat and the ratchet anvil have an angle adjustment function, and the power of the driving mechanism can be smoothly transmitted to the ratchet set, as in the patent of US Pat. No. 5,784,934. In one case it is. [New content] M3 5 8702 Only the various pneumatic/electric ratchet wrenches of the above-mentioned US patent case can be adjusted at any angle, but the overall structure is complicated, and the number of groups (four) is large. The manufacturing and assembly costs are high, and it is easy to cause failures _ 'and increase maintenance costs' and shorten the service life. The stability of the board-turning operation and the degree of (four degrees) are not ideal, and it is necessary to improve it.

為供進一步瞭解本創作構造特徵、運用技術手段及所預 期達成之功效，兹將本創作使用方式加以敘述，相信當可由 此而對本創作有更深入且具體之瞭解，如下所述： 請再參閲圖三、圖七與圖八，由於本創作氣動/電動棘 輪扳手之棘輪殼體⑷係活㈣設於棘輪殼座⑶上，且該棘 輪站⑸、轉紐⑻、棘輪組⑺可與棘輪殼體⑷組裝成—體 結構，因此，當❹者操作該棘輪扳手時，便可藉甴棘輪殼 體⑷與棘輪殼座⑶間之相對樞轉擺動，任意地調整連動該 M358702 棘輪砧（5)之角度位置，如圖八所示，俾令使用者得以依據 不同的工作環境或空間，來順利扳轉操作該棘輪扳手；需特 別說明的是，由於該棘輪組（7)與棘輪砧（5)相同，會隨著棘 輪殼體（4)調整擺動，並連動位於棘輪組（？）與驅動機構（2) 間之曲軸（8)。 因此，藉由本創作曲轴（8)所構成之萬向接頭結構，該 曲軸（8)之出力軸（83)便可順利地隨著棘輪組（7)擺動，而與 曲軸（8)之入力軸（81)形成任意彎折角度，並使該入力軸（81) 與出力轴（83)在任意彎折角度時，亦能產生動力傳遞作用， 而不會影響驅動機構（2)與棘輪組（7)間之連動； 據此，俾使該棘輪扳手之棘輪砧（5)隨棘輪殼體（4)樞轉 調整任意操作角度時，仍能順利地達到動力傳遞作用，以應 付各種扳轉工作，同時，由於該曲軸（8)結構相當簡單，組 成構件少，操作穩定順暢，因此，可有效降低生產製造與組 裝成本，亦可減少故障率與延長使用壽命。 綜上所述，本創作在同類產品中實有其極佳之進步實用 性，同時遍查國内外關於此類結構之技術資料，文獻中亦未 發現有相同的構造存在在先’是以’本創作實已具備新型專 利要件，爰依法提出申請。 惟，以上所述者，僅係本創作之一較佳可行實施例而 已，故舉凡應用本新型說明書及申請專利範圍所為之等效結 M358702 構變化，理應包含在本新型之專利範圍内β 【圖式簡單說明】 圖一為本創作具角度調整之板手之立體示意圖； 圖二為本創作具角度調整之板手設置曲軸之立體示意 圖三為本創作具角度調整之板手之立體分解示意圖； 圖四係本創作额、棘輪組以及曲軸之組合狀態示意 圖五為本創作曲軸之分解示意圖； 之剖面示意圖；以及 之動作示意圖。 圖六為曲軸設置於板手之剖面示意圖 圖七係本創作具角度調整之板手 圖八係本創作具角度調整之板手In order to further understand the characteristics of the creation of the creation, the use of technical means and the expected results, we will describe the use of this creation, I believe that you can have a deeper and more specific understanding of this creation, as follows: Please refer again Referring to Figure 3, Figure 7 and Figure 8, the ratchet housing (4) of the pneumatic/electric ratchet wrench is set on the ratchet housing (3), and the ratchet station (5), the switch (8), the ratchet set (7) and the ratchet The housing (4) is assembled into a body structure, so that when the latter operates the ratchet wrench, the M358702 ratchet anvil can be arbitrarily adjusted by the relative pivotal swing between the ratchet housing (4) and the ratchet housing (3). The angular position, as shown in Figure 8, allows the user to smoothly operate the ratchet wrench according to different working environments or spaces; it is necessary to specifically note that due to the ratchet set (7) and the ratchet anvil ( 5) The same, it will adjust the swing with the ratchet housing (4), and interlock the crankshaft (8) between the ratchet group (?) and the drive mechanism (2). Therefore, with the universal joint structure formed by the crankshaft (8), the output shaft (83) of the crankshaft (8) can smoothly swing with the ratchet group (7), and the input shaft of the crankshaft (8) (81) Forming an arbitrary bending angle and making the power input shaft (81) and the output shaft (83) at any bending angle also generate power transmission without affecting the driving mechanism (2) and the ratchet group ( 7) linkage between the two; according to this, the ratcheting anvil (5) of the ratchet wrench can be smoothly transferred to the rocker casing (4) to achieve the power transmission function to cope with various turning operations. At the same time, since the crankshaft (8) has a relatively simple structure, few components, and stable operation, the manufacturing and assembly costs can be effectively reduced, and the failure rate and the service life can be reduced. In summary, this creation has its excellent progress and practicality in similar products. At the same time, it has checked the technical information about such structures at home and abroad. The same structure has not been found in the literature. This creation has already possessed new types of patent requirements, and applied for it according to law. However, the above-mentioned ones are only one of the preferred embodiments of the present invention. Therefore, the equivalent configuration of M358702, which is applied to the present specification and the scope of the patent application, should be included in the scope of the patent of the present invention.
