New description: [New technical field] • This creation is related to the structure of the ratchet wrench, especially a ratchet wrench - the back side of the toothing includes three different curved surfaces, the first curved surface The ratchet wrench structure is made more rigid with the clamping structure between the teeth and the second pocket. [Prior Art] 'As previously known, the conventional ratchet wrench structure is as described in U.S. Patent Application No.: 3,436,992, the structure of which is characterized in that the working end of the wrench handle is provided with a first pocket and a second capacitor. a slot, the first slot and the second slot are in a communicating manner, the handle handle is provided with a control slot at a suitable position on the handle surface, the control slot is provided with a through hole, and the through hole is a control slot and a second slot The ratchet wheel is pivotally disposed at the first pocket of the wrench handle, and the outer circumference of the ratchet wheel is provided with a ratchet portion of the plurality of teeth; Φ the opposite tooth system is received in the second pocket of the wrench handle, The teeth side is provided with a plurality of occlusal teeth, and the occlusal teeth are engaged with the ratchet portion of the ratchet, and the back side of the occlusal teeth is provided with abutting surface, and the two teeth can be displaced in the second cavity In order to control the steering of the ratchet, the abutting surface of the toothing is abutted against the wall surface of the second receiving groove; a control member is disposed in the through hole of the control groove, and a rivet is attached to the second receiving groove to be solid with the control member The control member is pivoted on the control slot, and the control member is rotatable and dialable The second tooth is displaced to control the engagement of one of the teeth with the ratchet and the other tooth system is disengaged from the ratchet, thereby controlling the direction of rotation of the ratchet wrench. However, the lack of this patent lies in: the third figure of the second tooth is shown in the third figure, the side of the tooth is provided with a plurality of bite-and-pushing positions, and the side surface of the tooth is provided with a surface, when the control piece moves /, the middle tooth makes the bite tooth mesh with the ratchet portion, and the bite tooth system and the ratchet portion are disengaged, and the back is returned to the wall surface of the second cavity, and the control member is used to dial two =旋旋方方6 / 卞锴动. Haiyi makes teeth to control the ratchet=direction, but the abutment of the tooth is made by the single-arc two-arc line. The tooth is not smooth when the teeth are retracted. This is the patent:: Parts == The two tanks are fixed with the control member so that the control is controlled on the control groove of the wrench handle, but the control member and the rivet are difficult to use, and the cost of the rivet structure is increased to another one. For example, the US-China Patent No. 6 8 5 7 3 2 'The Taiwan Patent No. 〇9 2 2 () 5 9 3 5, the improvement of the hand structure, including a wrench structure (work The driving head end (11) of the boring plate (10) is provided with a drive: a C and a guiding groove (14), and the yoke: (12) is directed to the control slot (13), which controls the slot. - an action groove (15) communicating with a predetermined position 叩 (14) of the guide groove (丨4), and a directional control groove (1) and a drive accommodating groove (12 = forming a space portion) 1 6 ) ; τ does not 峨斲 - drive body (20) 'The drive body (2 〇) is placed in the drive housing of the wrench handle (i Q) by rotating M374388' (2 0) The outer edge is provided with an annular arrangement of the spur wheel portion (2) direction block (30) 'the two-direction block (3 〇) the top member (31)' the two-direction block (30) is set In the guide groove (14) of the pull 0), it can be worn with the guide groove (1 pair of sliding relationship, and the top direction block (3 〇) top surface = :; 3:) is worn on the plate handle (10) Direction control = 4 0) 'The direction control (40) is pivot: = In the direction control slot (13), the direction control = (4〇) 1 guide groove (412) is for the two directions The block (3 = the sliding portion (3 0 3 ) is accommodated, and the sliding direction can be reversed in the guiding groove (411) by the operation direction control member (4 〇), which is the third and fourth figures of the patent publication.

[The new content] The main purpose is: the ratchet wrench is made of the second side of the tooth with the same arc surface, the first-arc surface makes the tooth and the second In the case of Beibei, the second arc surface has a tooth retraction. In particular, this creation is about a ratchet wrench structure, which should include: - the system has a first-cavity, a second pocket, and a control slot. And the penetrating portion; the second system is disposed in the first cavity; the second toothed system is placed on the two sides of the seventh side, and the abutting surface includes a first curved surface, a second curved surface, and The second arc surface 'the first arc surface is the same as the center and the same radius of the second pocket, and the first intersection line is tangent to the edge of the round sauce'. The first arc surface and the second arc surface and the center of the circle are second The intersection line has 3 〇. 44 〇. The first arc surface is horizontally tangentially cut into a first tangential line, and the second chord is a second tangential line, and the distance between the two tangents is Η 1 and The height is made of the back teeth 13⁄4—©μ — 7- _ points one to two times; one elastic element is mounted on the control groove and the bottom-side protruding control surface is controlled by the two teeth. The cavity is disposed in the penetrating portion, and when the control surface is rotated, the protruding column is interlocked to move the tooth to be displaced.
