INSTRUCTIONS: [Technical Field] The present invention relates to a hand tool, and more specifically, to a ratchet wheel ratchet, the ratchet ratchet has a relatively long service life. [Prior Art] According to the ratchet wrench, a ratchet is attached to the head of the wrench, and the ratchet has a one-way rotation in the head, so that the ratchet wrench has a one-way pulling effect. In the conventional technique, the action pattern between the ratchet and the head of the wrench can be divided into a manner of slamming back and a method of occluding the teeth. It is known that a ratchet wrench that is not in the form of a return can be as shown in the new patent application case of the 092216589 5 Tiger (Announcement No. M24n76) "Structural Improvement of Wrench Tool". The structure can be as shown in the first figure, having a ratchet wheel (15) installed in the circular chamber (4) of the head (12) of a wrench (10) and rotatable. A plurality of ratchets (16) are provided on the circumferential surface of the ratchet (15). Each of the ratchets has a ui root (161), a tooth end (162), and a tooth back (163). The stupid back (10) is a slope so that the gap between the back of the tooth and the circumference of the chamber (10) is rooted by Tonggen. (Toward the tooth end _ reduction. A plurality of rollers (10) are respectively disposed between the ratchets (10) and the chamber (14). 1 The direction of the drawing is correct, when the ratchet (15) is in the chamber (14) Rotate the k' roller (18) clockwise to move toward the root (161) of the ratchet (16) so that the ratchet (15) can rotate freely in the valley to (10). Conversely, when the ratchet (10) is counterclockwise When the direction car is moving (or the wrench is turned clockwise), the roller (10) is tied to the end of the body to make the ratchet to the roller (18), and cannot be rotated. Therefore, when the plate is wrenched 200810885, The ratchet can be driven synchronously to drive the screwing elements, such as bolts, nuts, or sleeves. It can be seen that when the ratchet (15) rotates synchronously with the head (12), the roller (18) is pressed against the spine. On the tooth (16), after the wrench is used for a period of time, the pressure of the roller (is) will produce a dent (19) on the back (163) of the ratchet (16). Since the back (163) is a single tooth Slope of the slope, along with As the use time of the wrench increases, the dent (19) caused by the roller (18) pressing on the ratchet will gradually move forward, causing the ratchet to be damaged and even affecting the service life of the ratchet. When the mark (19) continues to move forward, the longer the length of the dent, the longer the distance between the root (161) and the end (a) of the dent continues to increase, and the user must move the wrench to a greater angle. The roller (18) can be moved from the root (161) to the concave

Please refer to (4) 3 and 4, which is a head wrench (10) provided by the present invention - a difficult embodiment, which has a handle (22) and a #81 on the end of the handle. (26), disposed in the head, the - ratchet (30) is mounted and the δ-helium wheel is rotatable and rotatable in the chamber (26). The peripheral surface of the ratchet (3G) is provided with a plurality of spines 2) at equal intervals, and its center is a driving portion (34). The driving portion (34) can be inserted into the sleeve as shown in the fourth figure. The insertion post can be formed with a ratchet (3()) body; or, or other components, but inserted into the socket (35) of the ratchet wheel, as shown in the third figure. As shown by the reference numeral (34) of the seventh figure, the polygonal sleeve is, for example, a quadrangular shape, a hexagonal shape, an octagonal shape or a twelve-corner shape for fitting a screwing member or a sleeve. Each ratchet (32) has a _ tooth root (4 〇) and a tooth end) returning to the moon (45), which is connected between the tooth root (40) and the tooth end (42), and is inclined to make The gap (g) between the back of the tooth (45) and the circumferential surface of the chamber (26) is gradually reduced from the root to the end of the tooth. A plurality of latching members (10) are beads or cylinders respectively mounted on the ratchets 200810885 ( 32) In the case of the compensation, in the case of the clamping element (the movement of the toothed end (10) of the ratchet tooth, the ratchet (32), the clamping member and the peripheral surface of the chamber will be activated. The head of the wrench can drive the ratchet. The invention is characterized in that: , referring to the fifth figure, the teeth (10) of each ratchet (32) have one of the connected - bevel (451) and - the: bevel (452). ), the first bevel (451) is closer to the root (10) The inclined surface (452) is closer to the tooth end (42). The tangential direction (τ) of the two inclined surfaces (451) (452) and the ratchet (32) are divided into an angle with the angle of 02, wherein the angle of the 'Μ is greater than The angle, in other words, the second bevel (452) is inclined relative to the first bevel (451). The wrench (10) is in use, in the direction of the third figure, when the ratchet (10) is clockwise with respect to the head (10) The wrench is counterclockwise, and the latch (10) rolls in the direction of the root (40), that is, moves toward the wide end of the gap (8). The ratchet is rotatable. Conversely, the wrench is clockwise. When the direction is pulled, the latching member (5〇) moves toward the tooth end (42), and the gap (8) is gradually reduced, so that the ratchet (32), the latching member (50) and the chamber (26) are mutually facing each other. The card engine, so when the wrench is pulled, the ratchet (3〇) can be driven to rotate the screwing element. Please refer to the sixth figure. After the wrench is used for a period of time, the card (10) will be the tooth of the ratchet (32). The back (45) has a dent (49) 'The indentation occurs on the first: bevel (451). As the time of use increases, the denier (the 49 degraded tooth end (42) direction moves' On arrival When the two slopes (452) are located, the slope of the slope is larger, which slows down the signs of the dents (49) moving forward, making the ratchets less prone to double damage and lifting the life of the ratchets and ratchets. By setting the second slope (10) with a larger slope, the thickness of the ratchet (32) 200810885 is increased, the structural strength of the ratchet is increased, and the spine (four) is easily broken. Thus, the service life of the ratchet is also extended. In addition, since the dimple (49) is less likely to move forward when it reaches the second inclined surface (452), the distance between the root (4〇) and the end of the dimple (b) is maintained at a certain length, Will continue to grow, so that the angle of the wrench that moves the clamp member (10) from the root to the end of the indentation (b) remains fixed, and the angle of the pull does not continue to increase, so that after the wrench is used for a period of time, Still have certain: Spirit: Degree. Therefore, the ratchet provided by the present invention can effectively reduce the damage of the ratchet and improve the strength of the ratchet. And the wrench still maintains a considerable sensitivity as the material is increased. The above is only the specific embodiment of the present invention, and the scope of the present invention is not limited thereto. Any modifications or equivalent variations that come within the technical scope of the invention are still within the scope of the invention. ^ In summary, the 'Day of the Day' (the fourth day) is the design of Wei in the article, and has the effect of improving the effectiveness. When it has been combined with the patent requirements, Mai applied. Praying for the merits of the members of the board of directors, in order to encourage the Chinese people to innovate in the invention, to make a detailed examination of the invention, and to grant the patent in this case as a prayer in the early morning. 200810885 [Simple description of the diagram] The first picture is a conventional one.
