Description of the Invention: [Technical Field] The present invention relates to a ratchet wrench structure, and more particularly, a ratchet wrench of a ratchet wrench can be removed and replaced with a ratchet of a different sleeve portion. A ratchet wrench with a replacement part that is easily replaced when damaged. [Prior Art] As previously known, a ratchet wrench structure having a multi-size use with a replaceable ratchet is used, such as U.S. Patent No.: US 6 7 8 9 4 4 9 B 2, with Taiwan Patent Application No.: 0 9 1 2 1 9 2 1 1, Patent name: Ratchet wrench for easy replacement of tool head. The patent application scope is: a ratchet wrench for facilitating replacement of the tool head, the ratchet wrench is mainly formed with a larger head at the end of a handle rod, and a tool head and a ratchet block are accommodated in the head portion. The utility model is characterized in that: a tool head pocket with a bottom edge protruding from the ring piece is formed on the head of the shank, and the head is formed with a spine pocket corresponding to the tool head pocket on the side adjacent to the shank, and The head is provided with a ratchet block capable of automatically resetting forward in the spine pocket, and a top surface of the head is formed with a recessed groove on the top edge of the corresponding spine pocket for inserting a cover sheet; The middle edge of the outer edge of the head is formed with a limit ring groove, and the ratchet block of the other wall surface is formed with a limit protrusion corresponding to the limit ring groove in the middle plane portion, and the top surface of the spine block is convex. The utility model has a lever which can pass through the cover sheet, wherein the center of the cover sheet forms a corresponding rearwardly extending dial, thereby forming a ratchet wrench which is excellent in torsion resistance and can replace the tool head for replacing the tool head. By. 3 201242725 The main advantage of the patented structure is that the limit ring groove 6 2 of the tool head 60 is clamped by the limit bump 64 of the ratchet block 6 3 , and the tool head 6 q gp is pivoted to the tool head pocket 5 2 inner 'and the ratchet 6 3 series can be displaced backward, so that the limit projection 64 is disengaged from the limit ring groove 62, and the tool head 6 can be taken out from the tool head groove 5 2 And replace the tool head of another size 60. ', but the absence of this patent is: 1. The tool head 6 does not need to have a limit ring groove 6 2, the limit ring groove 6 2 is more than one processing cost, and the limit ring groove 6 2 also makes The thickness of the ratchet 6丄 is reduced. 2, the head 5 1 of the shank 5 系 is provided with a vacant groove 5 6 for the cover piece 70 to be embedded 'as shown in the figure'. The vacant groove 56 is a special shape, and the vacant groove 5 6 is required The boring and milling tool processing, the milling cutter processing will make the shank 5q have a larger 6 upper, so that the increase of the second screw is also increased by the screw 3, and the need to provide the cover γ 〇 is provided in the vacant slot 5 piece 70 cost, and As shown in the picture, there is no need for cost. The ratchet of the wheel wrench can be used to take the ratchet of the wheel, and the inside of the body can be set to 201242725. If the piece is damaged, it is quite easy to replace and the ratchet solution of the replacement part is solved: the technical means of the problem: "the ratchet wheel is equipped with two body devices (4) - a tank, a second tank, a second tank and a fourth tank; - a spine h, a system = a part, a groove, a tank, a groove, a groove, a restriction Block, even = dial; - buckle buckle is set at the buckle groove, the buckle is fastened to the block ^ :: the tooth does not come out of the third pocket; - the top part and the elastic element = in the bullet hole It must be placed on the back side of the tooth to make the two sides of the tooth: : the first - the outside of the groove; when the hand presses the button to move the tooth to move backward: = the distance of the tooth is not removed. The restriction block is no longer locked in the buckle Slot position:; Compared with the effect of the prior art: the ratchet system = ratchet 'such a system can be matched with multiple specifications;; two = such as:: tooth reduction =. When the ratchet is replaced, the β: bottom: if the tooth, the top part and the bullet need to be replaced: the segment S can be used for the three parts, the ratchet wrench structure e of the invention is the same as the ratchet and the buckle. Buckle groove ί:;: The buckle is used to limit the teeth, thus saving the cost of developing new zero ^ 201242725. In order to make the structure and composition of the present invention fully understood by the members of the fishing bureau and those skilled in the art, the following description is only for explaining the implementation of the present invention. For example, it is not intended to limit the invention in any way, and any modifications made in the spirit of the invention are still within the scope of the invention.
