Description of the invention: [Technical field to which the invention pertains] In the context of a hand tool, it is referred to as a ratchet wrench ratchet wheel. The ratchet wheel has a relatively long service life. [Prior Art] Press the 'ratchet wrench' on the head of the wrench to install the ratchet. The ratchet has a one-way rotation in the head to make the ratchet wrench produce a one-way pull. In the driving and listening, the action between the ratchet and the head of the wrench can be divided into a way of engaging the teeth and a method of not engaging the teeth. It is known that the ratchet wrench of the non-toothed approach can be as shown in the new patent pre-existing case of the "Structural Improvement of the Hand Tool" No. 92216589 (Announcement No. Μ24ιΐ76). The structure can be as shown in the first figure, having a ratchet wheel (I5) mounted in a circular chamber (10) of the head (10) of a wrench (10) and rotatable. A plurality of ratchets (16) are provided on the circumferential surface of the ratchet (15). Each ratchet root (161) '-tooth end (162) and one tooth back (163), the back door 63, is a bevel, so that the gap between the back of the tooth and the circumference of the chamber (14) is made up of teeth The root (161) is reduced toward the tooth end (162). A plurality of rollers (18) are respectively disposed between the ratchets (16) and the chamber (14). In the direction of the drawing, when the ratchet (15) rotates clockwise in the chamber (14), the 'roller (18) moves toward the root (161) of the ratchet (16), making the ratchet ( 15) It can rotate freely in the valley room (14). Conversely, when the ratchet rotates counterclockwise (or the wrench is turned clockwise), the roller (18) moves toward the tooth end (162). Since the gap between the tooth end (162) and the chamber (14) is gradually reduced, the ratchet is caught by the roller (18) and cannot be rotated. Therefore, when the wrench 5 1328493 is pulled, the ratchet can be driven synchronously to drive Turn screw components, such as bolts, nuts, or sleeves. It can be seen that when the ratchet (15) rotates in synchronism with the head (12), the roller (18) is pressed against the ratchet (16). After the wrench has been in use for a period of time, the pressure of the roller (18) will create a dent (19) in the back (163) of the ratchet (16). Since the back of the tooth (163) is a slope with a single slope, as the use time of the wrench increases, the dent (19) caused by the roller (18) pressing the ratchet will gradually move forward, causing the ratchet to be affected. Damage, even affecting the life of the ratchet.
再者’當凹痕(19)持續往前移動時，凹痕之長度愈長，齒 根(161)與凹痕末端(a)間之距離即持續增加，則使用者須將扳 手扳動更大的角度後’始能令滾柱（18)由齒根（161)處移往凹 痕末端(a) ’以便卡住棘輪。如此，凹痕愈長，則扳手之靈敏 度即日漸降低。 【發明内容】Furthermore, when the dent (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 more. After a large angle, the roller (18) is moved from the root (161) to the end of the indentation (a) 'to catch the ratchet. Thus, the longer the dent, the lower the sensitivity of the wrench.

The fourth embodiment of the present invention is a perspective view of the ratchet of the preferred embodiment. The fifth figure is a partial enlarged view of the third figure. The sixth figure shows the state in which the ratchet of the ratchet of the present invention generates a dent. Figure 7 is a top plan view of a ratchet of another preferred embodiment of the present invention. Referring to Figures 3 and 4, there is provided a wheel wrench (10) having a handle (22) and a y IK24 at one end of the handle. A circular chamber (26) is provided in the head for a ratchet (3 〇). Also, the 4 ratchets are rotatable in the chamber (26). The ratchet wheel (30) has a plurality of ratchet teeth (32) at equal intervals on its circumferential surface and a drive portion (34) at its center. The driving portion (34) can be connected to the sleeve as shown in the fourth figure. The post can be integrally formed with the ratchet (30); or it can be an individual part and inserted into the socket (35) of the ratchet, as shown in the third figure. The driving portion of the ratchet can also be a polygonal sleeve, such as a four-corner opening, a hexagonal shape, an octagonal shape or a twelve-corner shape, as shown in the reference numeral (34) of the seventh figure, for arranging the screwing component or the sleeve. cylinder. Please refer to the fifth figure, each ratchet (32) has a tooth plate (4G) and a tooth end (42) ° a tooth back (45) ' is connected to the root (40) and the tooth end (42) And inclined, so that the gap (g) between the back of the tooth (45) and the circumference of the chamber (26) is from the root to the end of the tooth (5〇), which is a ball or a cylinder, respectively Provided in the gaps (g) of the ratchets 1328483 (32) and the valleys (26), when the latch member (5()) moves toward the tooth end (42) of the ratchet, the spine will be made The teeth (32), the latching member and the peripheral surface of the chamber have a latching action so that the head of the wrench can drive the ratchet. The invention is characterized in that: referring to the fifth figure, the back (45) of each ratchet (32) has one of the first inclined surface (451) and the second second inclined surface (452), the first inclined surface ( 451) is closer to the root (40) and the second bevel (452) is closer to the tooth end (42). The slanting faces (451) (452) and the tangential direction (τ) of the ratchet teeth (32) respectively form an angle of an angle, wherein the angle of 02 is greater than the angle of β1, in other words, the second slope (452) is Compared with the first inclined surface (45 inclined. The wrench (20) is in use, according to the direction of the third figure, when the ratchet (10) is in the direction of the lion with respect to the head (10) (ie, the wrench is in the direction of the hour hand) The clamping member (50) is rolled in the direction of the tooth root (40), that is, the movement to the gap (the wide end of the magical movement) can be rotated freely. Conversely, when the wrench is turned clockwise, the clamping member (5〇) moves toward the tooth end (42), and the gap (8) gradually shrinks, so that the ratchet (32), the card (5〇) and the chamber (26) face each other, so the wrench is pulled. When the ratchet (3〇) is driven, the screwing element can be rotated. Referring to the sixth figure, after the wrench is used for a period of time, the clamping element (5(7) is pulled out on the #back (45) of the ratchet (32). a dent (49) which occurs on the first slope. As the time of use increases: the dent (four) gradually moves in the direction of the tooth end (four), and when it reaches the second slope (452), Qing) The slope is large, which slows down the sign of the dent (49) moving forward, making the ratchet (32) difficult to double pick and improve the service life of the ratchet and ratchet. The second bevel _, the increase in the thickness of the ratchet (32) 8 1328493 'increased its structural strength and _ property, and made the thorns easily collapse. This will also extend the life of the ratchet. In addition, due to the dent ( 49) When it reaches the second inclined surface (452), it is not easy to move further. The distance between the 'root (4〇) and the end of the dimple (9) is maintained at a predetermined length, and will not continue to grow. The angle of the wrench (10) moved from the root to the end of the indentation (b) is maintained, and the angle of the pulling does not continue to increase, so that the wrench retains a certain sensitivity after a period of use.
