[Prior Art] A conventionally used multi-size ratchet open end wrench, as shown in FIG. 8, includes a grip 8 and a driving portion 7 combined with a grip 8, the driving portion 7 having an upper jaw 71, a movable lower jaw 72 and a card abutting portion 7 3 between the upper and lower jaws 7 1 and 7 2, and a bottom recess 7 2 1 and a projection 7 2 2 are provided at the bottom end of the lower jaw 7 2, The first recess 7 2 1 should be provided with a second recess 7 4 having a thread 741 in the driving portion 7, and the second recess 74 can be sequentially provided from the inside to the outside for the bump 7 of the lower cymbal 7 2 . 2, a spring 7 5 and a lock firmware 7 6 capacity. The above-mentioned multi-size ratchet open-end wrench structure has to be subjected to drilling, cutting, grinding and rolling threads in the manufacturing process, so that the cost is high, and the bumps need to be closely matched with the grooves. Therefore, it is difficult to process, so how to make a multi-size ratchet open wrench structure that is easy to process and low in cost is the technical focus of the present invention. SUMMARY OF THE INVENTION The main object of the present invention is to solve the above problems and provide a ratchet wrench, which is provided with a movable ratchet block, a positioning ring and a spring in the receiving groove of the driving portion, so that the spine The tooth block can be moved and adjusted according to the size of the workpiece, so that the locking portion of the ratchet block and the driving portion can form a clamping function for the workpieces of different sizes, and therefore has the function of being able to pull the workpiece of different sizes. 5 200800509 According to a second object of the present invention, since the ratchet block of the present invention has a simple shape and is easy to process, and the positioning ring and the spring are both specifications, the price is low and the convenience is obtained. Therefore, the present invention only needs to be drilled in the driving part. The spring, the positioning ring and the ratchet block are installed in a slot, and the assembly is completed, so that the utility model has the advantages of simple processing and low cost. For the purpose of the foregoing, the present invention includes a driving portion and a grip integrally formed with the driving portion, wherein the driving portion has a fastening portion away from one end of the grip, and the fastening portion is u-shaped. And a accommodating groove is disposed in the driving portion toward the gripping direction, and a spring, a positioning ring and a movable ratchet block are sequentially disposed, and the inner side wall surface of the accommodating groove has a adjacent fixing section An annular recessed hole for receiving the above positioning ring. The above and other objects and advantages of the present invention will be readily understood from Of course, the invention may be varied on certain components, or in the arrangement of the components, but the selected embodiments are described in detail in the specification and their construction is shown in the drawings. [Embodiment] Please refer to Fig. 1 to Fig. 5, which shows the structure of the embodiment selected for the present invention, which is for illustrative purposes only and is not limited by such structure in the patent application. The ratchet wrench of the present embodiment, as shown in FIGS. 1 and 2, includes a driving portion 1 and a grip 2 integrally formed with the driving portion 1, wherein the driving portion 1 is away from the grip 2 One end has a fastening section 1 1, the fastening section 1 1 is U-shaped, and the driving part 1 faces the grip 2 direction 6 200800509 and has a mouth groove 1 2 '俾 for sequential installation - spring 3, - positioning ring 4 > moving ratchet block 5, in this embodiment, the ratchet block $ is made up of /, , - number of spines 5 1 1 ratchet segment 5 1 and a spine The tooth segment 5 1 is formed by an extension portion 5 2 extending in the direction of the grip = direction, and the ratchet segment 5 切 is aligned with the top end of the further 1 1 1 , and has a garment 曰 5 2 adjacent to the bottom end of the extension portion 5 2 . 1, for the end of the spring 3 is installed, so that the spring 3 is limited to be between the positioning ring 4 and the ring groove 5 21, and the receiving groove! 2 The inner wall surface _ , # near the fastening section has an annular recessed hole 121 for accommodating the above-mentioned positioning ring 4 . μ; In the embodiment of the present, when the workpiece is a large screw 6 of a large size, as shown in the third row, the user can lift the ratchet block 5 slightly upward by the hand, and then put the large screw 6 into the spine. In the working space i 3 formed on the ratchet section 5 of the tooth block 5 and the clamping section 1, the large-sized screw 6 is subjected to the locking section 1 1 and the ratchet section 5 by using the clamping section i 丄1 card system, and since the ratchet block 5 can be supported by the positioning ring 4, the large screw 6 can be pulled to loosen or lock the large screw 6 and can be used. Thereafter, the ratchet block 5 can be returned to the original position by the restoring force of the spring 3. When the size of the workpiece is a small screw 6 2, as shown in Figures 4 and 5, the user can lift the ratchet block 5 upwards by hand, and then place the small screw 6 2 into the ratchet block 5 In the working space 14 formed by the ratchet segment 5 1 and the clamping segment 1 , the small screw 6 2 is subjected to the clamping segment χ μ , the back segment 5 1 is clamped, and the ratchet block 5 can be subjected to the positioning ring. 4 top support ' Therefore, the small screw 6 2 can be pulled to loosen or lock the small 7 200800509 type screw 6 2, and after use, the spring 3 can be used to restore the spine The tooth block 5 is returned to its original position. It can be seen from the above that the present invention can be used for workpieces of different sizes, so that the locking portion of the ratchet block and the driving portion can form a locking effect on workpieces of different sizes, thereby performing the action of loosening or locking the workpiece, and therefore, is applicable. It can be used to move the workpieces of different sizes. Furthermore, since the ratchet block of the present invention has a simple shape and is easy to process, and the positioning ring and the spring are both specifications, the price is low and the convenience is obtained. Therefore, the present invention only needs to drill a receiving groove in the driving portion, and then The spring, the positioning ring and the ratchet block are sequentially installed, that is, the assembly is completed, so that the processing is simple and the cost is low. Of course, there are still many examples of the present invention, only the details of which vary, for example, the present invention can also be used to pull a nut or the like. Please refer to FIG. 6 , which is a second embodiment of the present invention, wherein the ratchet segment 5 1 A has a plurality of ratchet teeth 5 1 1 A, and each ratchet tooth 5 1 1 A is held by the grip 2 A toward the card. The solid segment 1 1 A direction is gradually enlarged. Referring to FIG. 7, which is a third embodiment of the present invention, the ratchet wrench includes a driving portion 1 B and a grip 2 B, wherein the driving portion 1 B has a distal end from the grip 2B. The fixing portion 1 1 B is provided with a receiving groove 1 2 B in the direction of the driving portion 1 B facing the grip 2 B. The spring is provided with a spring 3 B, a positioning ring 4 B and a movable portion. In the present embodiment, the structure of the ratchet block 5 B is the same as that of the first embodiment, and an adjusting member is disposed between the bottom edge of the clamping portion 1 1 B and the receiving groove 1 2 B. 1 6 B to adjust the displacement of the clamping section 1 1 B. 8 200800509 When the screw 1 7 B is rotated by the invention, the clamping section 1 1 B can be moved in the direction of the ratchet block 5 B by the rotation adjusting member 16B, so that the working space 13 3 B becomes smaller. The screw 1 7 b is clamped by the clamping section 1 1 b and the ratchet 丨 5 1 B, and the ratchet block 5 b can be received by the top floor of the positioning ring 4 B so that the screw 1 7 b can be pulled The action is to loosen or lock the screw 1 7 B, and the money can be used to restore the ratchet block 5 B to its original position by the restoring force of the elastic crest 3 B .
