A set of push plates (4) arranged in the shape of ε at the front end of the bullet, and a Ε-shaped fastener 144 inserted at the lower end of the rotary dial 141, and the push plate (4) is biased by the spring 142. The card material (1) 吏 side recess (1), the condensing switch 141 can move the card block 13 to the left or right position by the push plate 143 for switching the engagement position of the card block 13 and the ratchet drive head 12 The effect of controlling the direction of rotation of the ratchet drive head 12 is achieved. Although the ratchet wrench 10 can achieve the function of direction switching, the rotation setting (4) 2 of the ratchet wrench ig is interlocked with the click block 13 by the spring I U2 and the push plate 143. The card block blocks the inner wall surface of the 乂H wrench body 11 (four) to the limit position of the rotary dial H1, and the card (four) 13 passes through the left and right cleavage points, but there is no obstacle to the zone I. Rotating M361407 to dial the magic 4] In the course of use, it is easy to be mistakenly touched and cause mistakes, causing operator confusion. [New content] Therefore, the purpose of the present invention is to provide a switching type with good convenience. Ratchet wrench. Further, the present invention provides a switchable ratchet wrench comprising a ratchet single m-direction control unit, wherein: the wrench body: has a head end, and the head end is internally provided with a -th-chamber, adjacent On the side of the first-valley room, there is a 坌--------------------------------------------------------------------------------------------------------------------------- Early 70 has a shaft set in the first chamber. And a card is placed in the second chamber adjacent to the driving head. The driving head is provided with a ring tooth on the outer circumference, a ratchet portion is arranged on the front side of the card block, and a back portion is provided at the rear side. The concave portion and the clamping block can be displaced in the left and right of the second chamber to make the ratchet portion and the ring tooth belong to each other; the direction control unit, the button having the shaft and the second chamber, and the through-through a top member inside the button, and a positioning pin erected in the middle of the third chamber wall. The top member is springly pushed into the recess of the card block, so that the button is pulled by the top. The piece can be moved to the left and right direction of the block, and the top part is moved to the other end. (4) The third room interior wall moves. The positioning pin can form a clamp on the outer circumference of the button and the top piece is positioned. When the pin is pinned, the offside barrier can be formed. The effect of a new type is mainly to insert the clamp pin upright in the middle of the third cavity inner wall, so that the dial button forms a transposition barrier when switching the left and right direction, thereby dialing! It is intended to be convenient to use. [Embodiment] M361407 The following I::: type and other Technical content, features and functions, in the detailed description of the preferred embodiment of the =: formula, will be clear to see Figure 3, Figure 4 male smell c ^ and the new switch ratchet wrench in the first car father In the example of %, the main I 4 person 匕 3 a wrench body 20, a ratchet unit 3 〇 and a directional control unit 4 〇, 芏 $ ^ combination space «details the detailed structure and hand body of the above units 2G has a "head end 21, the head end 21 is internally recessed with a two-hole shape of the first chamber 211, adjacent to the first chamber - 2U side is recessed with a second skirt _*. 212 The second chamber 212 is provided with a cylindrical hole shape at the side, and a pin hole 214 is disposed at the middle of the third chamber. «Hai ratchet wheel early 30 has a drive head I1 with a shaft set in the first chamber 2ι, a control rod 32 disposed at the center of the drive head 31, a set of bullets arranged on the control #32, 33 sets The cassette steel ball 34, which is disposed inside the driving head 31, is in the vicinity of the chucking block 35 adjacent to the driving head. The driving head 31 is provided with a ring tooth at the outer circumference, for example, a plug portion 312 is provided at the end portion thereof. The control rod 32 is affected by the elastic force of the magazine 33, and the carding steel ball 34 can be protruded from the outer surface of the square bolt portion 312. . The latching block 35 is a slightly half-moon shaped block having a ratchet portion 351 at the front side and a resisting recess 352 at the rear side. The cartridge block % can be moved left and right in the second chamber 212. Displacement, the spine is sold with the ring sauce (1). The direction control unit 4 has a dial 41 in which the shaft is disposed in the third chamber 213, a top member 42 that penetrates the inside of the contact 41, and a positioning pin in which the upright insertion M361407 is embedded in the pin hole 214. 43. The dial 41 has a shaft portion 411 and a handle portion 412 provided at one end of the shaft portion 411 for the operator's hand to rotate. The shaft portion 411 is provided with a through hole 413 through the outer circumference, and a concave portion is disposed on the outer peripheral wall surface of the rear side. A groove 414 having a predetermined arc angle is recessed in the middle of the groove 414 with a notch 415 into which the positioning pin 43 can be inserted. In this embodiment, the top member 42 includes a spring 421, a hollow pin 422 and a steel ball 423. The spring 421 is sleeved in the through hole 413 of the button 41, and the front end of the top member can be biased against the hollow pin 422 to enter the card. In the abutting recess 352 of the block 35, the button 41 can be driven by the top member 42 to change the left and right direction to move the κ 421, and then the ball 423 can be pressed against the inner wall of the third chamber 213. Rolling movement. The positioning lock 43 is a long-shaped round pin, and one end portion 43 is provided at one end thereof. After the step portion 431 is inserted by the notch 415 of the dial 41, the clerk groove 414 is formed into a limit position. It is quickly positioned within the third chamber 213.丄The structure and shape of the new type (4) ratchet wrench (4), the receiver, and then the action of the new type and the expected effect of the performance as follows: Casing Π:: two in the general state of the sale of 41 by the top The shackle 42 is idle and interlocked, because the locating lock 43 protrudes from the third chamber & 'circumference wall'. If the button 41 is to be switched, the left and right steel balls 423 are blocked along the basin 2a - Ding Tian y, 7 Bei Cui pieces, Make::Γ;::When the wall moves, it will touch the positioning pin 43. It will not change the direction easily. 'Only in the operator's words*-to dial the 41 dial to switch a button 41, so that the steel ball 42 can... Slightly push the dial to let the dial (...) == and exceed the positioning lock... to change the direction position, as shown in Figure 6. M361407 In summary, the new type of switching ratchet wrench is known to be missing the ratchet wrench 10, and the technical means used is to insert a fixing-positioning pin in the middle of the inner wall of the third chamber 213: the body position lock 1 Highlighted in the third chamber 213 (four) (four) robbery 4, when the left and right switch, the positioning iron 43 on the charm 41 can produce ^ 2 41 to make the button 41 helmet sound to change the male Gu Shi t position barrier effect, think about. & direction, only when the operator confirms that it is necessary to cut the ancient:: the force can be over the positioning lock ":: change: (four) quite sure' has good usability. In addition, the positioning pin 43 pairs Dial button 41 made #
