The card-locking relationship between the block 60 and the driver 20. One end of the top block 60 is formed with a pivot end 61, and a top end of the top block 6 is opposite to the end of the pivot end 61 to form a latch end 62. The pivoting end 61 and the 99/09/17 supplemental and correction card end 62 are formed with a first surface 63 adjacent to the commutating block 7〇 and a second surface 64 remote from the reversing block 70. . The pivoting block 61 is pivotally connected to the pivoting slot 122. The pivoting end 61 has an arcuate surface and is pivotally connected to the pivoting slot 122 of the second receiving space 12. The top block 60 is attached to the ratchet 21 with a latching end 62 which is provided with at least one latching tooth 621 for being supported against the ratchet 21 of the drive member 2''. The top block 60 is provided with a positioning portion 65 on the first surface 63. In the embodiment, the positioning portion 65 of the block 60 is recessed on the first surface 63, and the positioning portion 65 has a positioning surface 66 recessed in the first surface 63. The latching end 62 of the latching end 62 closest to the first surface 63 of the top jaw block 60 is defined as a first molar 621, and the circular pivoting end 61 defines a tangent T'. This tangent τ is pivoted. a tangent point of the arc-shaped outer surface of the end 61 and an intersection of the first molar 621 and the first surface 63 of the latch end 62. The first surface 63 of the top block 60 is disposed substantially along the tangent line T. A flat shape. In the present embodiment, the positioning portion 65 of the top block 60 is recessed in the tangent line τ, and the positioning surface 66 is also within the tangent line T. The reversing block 70 has a shaft end 71 and two limiting portions 72. The shaft end 71 is pivotally disposed in the second receiving space 12, and the limiting position is; 72 is toward the top The pivoting end 61 of the block 6 延伸 extends, and the limiting portion 72 can selectively abut against the positioning portion 65 of one of the two top cymbal blocks 60 to form a gap between the reversing block 70 and the top cymbal block 60. Positioning status. The shaft end 71 is convexly disposed on one side of a coupling rod 711 passing through the pivot hole 121. The coupling rod 1337567 99/09/17 is used to couple a dial 32 outside the body 1 by means of a button 32. The toggle block 30 can be pivoted relative to the body 1 and the limiting portion 72 can be selectively abutted against the positioning portion 65 of one of the two top blocks 6〇. . The coupling rod 711 is formed in a non-circular cross section, and the dial 32 is provided with a coupling hole 321 which is fitted to the shape of the coupling rod 711. The two limiting portions 72 of the reversing block 70 are each formed with a limiting surface 73, and the two limiting surfaces 73 can selectively abut against the two top blocks 6〇.

On one of the positioning faces 66, and by the pushing of the elastic body 31, a positioning state is formed between the top block 60 and the commutation block 70. The cross-sectional position of the reversing block 7〇 defines a center line c, which passes through the center of the shaft end 71 and the center position between the two limiting portions 72. Divided into two halves that are bilaterally symmetrical, the two limiting portions 72 are divided into left and right limiting surfaces 73 by the center and the line c.

In this embodiment, the limiting surface 73 is disposed in a plane shape along the chord b formed by the two end points p, and the positioning surface 66 of the top cymbal block 60 is matched to the limit 60 1337567. Between the fan-shaped area S, such as ώ 7Λ can be raped ... ~ Hai change to block 70 and the block 60 is the right, the effect. Since the top (four) is subjected to the elastic body surface 64 against the commutation block 72, the = portion 65 will be abutted to the inter-position position. The reason is as follows, the _to block 70 does not arbitrarily return to the principle that the force F1 of the elastic body 31 is perpendicular to the force F, the positioning portion 65 of the fresh block 6G has a positive = The center has a radius force F2 perpendicular to the center of rotation of the top gamma - two of which are as follows: dry work, relationship

Fl*Rl=p2*R2 Since the half feR2 is much smaller than the radius R1, the positive force a 3! is several times larger than the force Π. Therefore, the limit of the commutation block 7() = the elastic body is resisted by the positive force F2 without reverse rotation = 2 will result. At the same time, the limiting portion 72 of the reversing block 70 also has a good positioning effect... the reaction force F3 is perpendicular to the two-force force reaction force F3 of the commutating block 7〇 and the positive force F2: the relationship between the radius and the radius force As follows: f4 is lost, and the two forces of F2 and F3 are equal in magnitude and opposite in direction, so that it can be ensured that the limiting portion 72 on the positioning portion of the page block 6〇 abuts, and the block 6() J = Reversing the soil 7 〇 so that the top end of the top block 60 "the body 31 pushes up and can produce a unidirectional rotation effect. As shown in the figure, the driving member 2 〇 relative to the body H) clockwise oblique = the movable member 20 can refer to Figure 9 and Figure 10, 4 rotate with the hour hand. When the field user money drive 20 is completely • 99/09/17 is added, corrected, the dial button 32 can be turned to make the limit surface 73 of the commutation block 70 The clamping surface 66 of the top block 60 generates a slip and pivots the top sill 6 to retreat, thereby compressing the elastic body 31, so that the limiting surface of the reversing block 7 乃 can leave the top block (10) The positioning surface (10) returns the commutating block to the middle position. The top cymbal block 60 on both sides of the reversing block 70 is abutting against the ratchet 22 of the driving member 2Q with the latching end 62. Therefore, the drive member will not be able to: the body ^ rotates clockwise 'cannot turn counterclockwise. That is to say, the drive 仟α疋 follows the body 〇 〇 synchronously transfer, at this time the operating body 1 〇 will be able to drive the drive member 20 to drive two The crop is rotated clockwise or square = tune (four) "" for all occasions. By the above operation, the key % of the wrench of the present invention can move the reversing wrench having the reversing positioning effect between three positions (pushing to the intermediate position and dialing to both sides). And because of this limit

The pivoting end 61 of the block 6° extends, so that the 嶋J can take a small angle to achieve the effect of moving to different positions, that is, =
