Description of the Invention: [Technical Field] The present invention relates to a ratchet wrench structure, and more particularly to a ratchet wrench having a toothed tooth and a convex arc tooth, so that the ratchet wrench has better rotation-motion Torque and smooth tooth removal. [Prior Art] As previously known, the conventional ratchet wrench structure, such as the U.S. Patent No. 5 9 7 9 2 7 4, is based on the fact that the body has a suitable length of φ end. a shank, the working end of the body is provided with a first receiving groove, and a second receiving groove having a smaller diameter is disposed at a side of the first receiving groove near the shank, and the upper and lower sides of the second receiving groove are The first receiving groove is in contact with the second receiving groove, and the second receiving groove is bored with a ballistic hole at a suitable position, and the elastic hole is longitudinally disposed; the ratcheting system is firstly disposed at the first The ratchet outer peripheral edge is provided with a ratchet portion with an annular arrangement of teeth, and a ratchet-shaped sleeve portion is arranged at the center of the ratchet wheel to be screwed by the screwing member; the tooth system is accommodated in the second capacity In the slot, the front side of the toothing is provided with a plurality of occlusal teeth, and the occlusal teeth mesh with the ratchet portion; one end of the elastic element is received in the ballistic hole, and the other end of the elastic element is attached to the tooth The teeth of the teeth are made to be in contact with the ratchet portion. Λ 'But the patent is missing: 'The tooth system uses the elastic element to abut against the inner side of the second pocket, so that the bite tooth meshes with the ratchet portion, but the elastic element is accommodated in the elastic element Drilling is provided on the wall surface of the second cavity, and if the curved wall surface of the second cavity is to be drilled, it is a very difficult processing procedure, because the hole is drilled in 201217106, The drill bit avoids the first angle and the angle of the drill bit, and the drill bit extends into the second tank interior. 2: 2:: After the inclined position, the inclined bullet hole is drilled, that is, the bore hole is the position. : The inclined hole of the three directions of the shaft is required to be (4) - the borehole hole is the material shortage thereof - as another patent case, the U.S. Patent No. U S 7 4 4 4 q η 3Β1' has its Taiwan Patent Application No. 〇 962158结构9 The structural improvement of the material wrench is composed of a wrench body, a knuckle block, a ratchet wheel and a limit ring, wherein the body of the wrench is provided with a ratchet hole of the beacon, the spine The perforation groove is provided at the periphery of the perforation - the ring is limited to the ring I', and the other side is provided with a ring-locking ring groove, and the ratchet hole is grooved toward the handle (4) The inner-arc-shaped arc shape accommodates the groove chamber; the knotted ratchet block is an arc-shaped bend = the focal shape is in the (four) recess--the edge portion is provided with a full ratchet, and the inner arc concave-edge portion is It has a lower and flat sliding surface, and one side of the ratchet is provided. There is another stop surface at the edge of the arc, and the arc convex portion outside the ratchet block is provided. a spring that pops up in the direction of the ratchet; the outer circumference of the ratchet is provided with a ratchet tooth, and the inside is provided with a rocking hole groove, and both end edges are provided with: 2 position % groove, the limit position is provided outside the circumference edge - the ring knot The groove is provided by the above-mentioned: 2 structure, the knotted rocker is provided with a spring at the outer arc convex portion, and the knotted ratchet block is placed in the receiving groove chamber of the wrench body in the same capacity as the elastic body, and the ratchet wheel is accommodated in the wrench = in the ratchet hole groove 'below the ratchet wheel with the limit ring groove and the wrench body limit ribs with 5 limit' wrench body of the ratchet hole groove on the other side with the limit ring with the card,, '3 ring groove closed Fix it so that the limit ring groove above the ratchet fits the limit ring with the limit ring. 201217106 This patent structure is required to be drilled on the wrench body with respect to the US patent. # _ yZ74 is not a processing cost. The wrench (4) has less loss: it is a relative advantage, but the patent structure also has The following defects are limited to the patented public goods. ^ Γ 51 V - The wrench body 50 is not shown. The ratchet wrench structure is provided with a 5 〇, a knotted 6 () and an elastic buckle 9. It consists of six components, six^two-in-one::: It is a complex multi-component assembly structure and adds element 2. Although it is not necessary to drill a hole in the wrench body, it needs to be after the ratchet 60 The side is provided with a magazine 梓1, and a port 6 〇y" The 弹6 6 series is accommodated in the knotted ratchet ^ ^ θ, so that the knotted knot 60 is required to be drilled after molding. The rear side of the engaging knot 6 Q is also curved like a drill, a drill groove, and as shown in the fourth figure, the ballistic groove is located; at the southernmost point of the plane, when the drill bit rotates rapidly, the contact is reached. In the case of a curved surface, the drill bit is easily displaced along the curved surface. The position of the drill cartridge is easily deviated, and the knotted ratchet is required to be drilled. The straight-slot technique is not large. When the small drill bit is drilled, the town head is quite easy to break. 0 3. As shown in the fourth figure of the bulletin or the eleventh figure, the magazine is in the longitudinal direction. The spring 6 4 abuts against the engaging ratchet 6 〇 the direction of the biasing force is also the longitudinal direction. The arrow shown in the fourth figure of the publication is the longitudinal direction, and the elastic top of the spring 6 4 is more difficult to make the knot. Thorn 6 The right rear side is close to the accommodating groove chamber 55 of the wrench body 1 2012 201217106 : No:: When the ball is not correct, the knot is squid 6. With the spine 有时 有时 有时 有时 有时 有时 有时 有时 有时 有时 有时 有时 有时As shown in the second figure, the magazine β spine 6 0 force side (four) is (four) direction, # _ 71 抵卡结〇 counterclockwise Μ碟# β 〜 ''hand body 1' knot spine elastic system will make the ratchet 7 〇带带. The ratchet block 60 is stationary, that is, at this time, the snail is more than the spring 64 is placed on the top of the accommodating groove chamber 55. The friction accommodating groove chamber 5 5 side surface, by the eleventh picture ear At the end of a 6 4, the system will produce when the retreat is - the idling of the angle - the end of the figure 6 〇 i collides with the accommodating slot; = ::: the knot is 6 ft 5 5 Produced as shown in the fifth picture of the Gazette:: There will be a idling phenomenon when the Γ Γ , , , , , , - - - - - - - - - - - - - - - - - - - - - - - - = = = = = = The system is i: the angle of the relatively large idling may be greater than five degrees, and the angle of the retreat is 丄: the ϊγ block has a ratchet in one side, and the other side has a ten-picture as shown in the figure. The fourth figure shows or uses the eighth tooth The ratchet phase 2 limits the number of ratchet teeth, and is only lower. The swiveling moment between the knotted ratchet and the ratchet is +3, t, r ratchet 60 is provided with a sliding surface 62, and As shown in Fig. 70::7 ^4, the sliding surface 62 is quite close to the ratcheting habit. Twelfth figure = the gap between the two is quite small, and when it is retracted, it is used to turn into the I. When the thirteenth picture or the twelfth picture is changed to 201217106 and becomes the fifth picture of the bulletin, the knot is easy to get stuck in the ratchet 7 (10) turn + = 1 when the part is formed, the end part 6 0 i Shape; ^ card knots 6 phenomenon is more obvious, the end of the 6 〇 1 turn stuck is more labor.丨 丨 冉 廇 廇 , , 如此 如此 = = = = = = = = 单向 单向 单向 单向 单向 单向 单向 单向 单向 单向 单向 单向 单向 单向 单向 单向 单向 单向 单向 单向 单向 单向 单向 单向 单向 单向 单向 单向 单向 单向 单向 单向The accommodating hole has a rim and a fixed ring groove at both ends, and is disposed in the accommodating hole toward the wrench. The ratchet is installed in the ratchet inner chamber and is matched with the arc-shaped block, and is in the arc-shaped end. The left and right sides are provided with a slanted chisel surface in the arc _ obliquely opened - a receiving groove, and the receiving groove °, the elastic member, and the - ratchet, the ratchet system is disposed in the accommodating hole 铍Γ / / The spine (4) is in contact with the spur tooth surface and the oblique tooth surface of the ratchet, and one end of the 5th seabow ridge is against the retaining edge of the accommodating hole, and the other end is fitted with a fixed slot, and is fastened with a -c shape It is located between the limit groove and the fixed ring; (4) The structure of the ί ί 利 case is relative to the US patent 7 4 4 4 9 0 3, and the ten pieces of the volley are diagonally offset, so that there is no sloshing when the splicing is not smooth and the sloshing is lost. The third point and the fourth point are missing, and the ratchet is provided with a flank surface and a spur surface, and both are combined with the ratchet of the ratchet, so that there is no such missing point 5] but the patent structure Still have the following missing. The convex end of the ratcheted fox is provided with a cavity, and a receiving groove is formed, that is, the hole of the ratchet tooth 20 0 is broken. And the second paragraph of the patent 7 4 4 4 903 2, the third picture of the bulletin, the left side of the 5th 〇, the left side of the slanting two f and the sixth figure, the ratchet: the lower corner shift, today When the tooth is retracted, the ratchet 2 0 system will have a left oblique back surface 21 and a ratchet ring 31, which are linear, and the two greens are separated from the human mother by a linear line: ΐ,! The τ system is in a state of coincidence. When the left-hand corner of the side surface of the slanted tooth surface is displaced, it is easy to collide with the ratchet and the surface.
