In order to understand the characteristics of the creation of materials, the use of technical means and the pre-achieved effects, we will describe the use of this creation, and believe that we can have a deeper and more specific understanding of this creation, as described below. As shown in the fourth and fifth figures, when the ratchet wrench is operated, the switching handle 332 is only required to be pulled left and right, so that the steel ball 3352 of the elastic abutting member 335 is respectively limited to the limit slot 314. In the meantime, the positioning effect is achieved, and at the same time, since the left and right meshing teeth 311, 312 are integrally formed, it is ensured that the left and right meshing tooth blocks 3U \ 312 are synchronized and reach the meshing tooth block group. 31 and the unidirectional positioning of the ratchet block 20 =, in turn, the abutting spring member 32 can provide the left 'right twisting return block 3U, 3 丨 2 - elastic abutting action to assist the top abutment, and when When the steel ball 3352 is located in the central limiting groove 3142, the left and right meshing blocks 311, 312 are not in contact with the ratchet block 20, so that the ratchet block 2 is in a state in which the rotating mechanism is idling. 'Monthly as shown in the seventh picture, the first use of the creation of the ratchet wrench The switch 332 is pulled and the steel ball 3352 is limited to the left limit 6 M360112, and the compression spring of the elastic abutting member 335 will abut the steel ball * shouting 13 for the steel ball 3352 to push outward In response to the force, further, the γ block 311 can be pushed by the force while driving the right meshing tooth block 312 to the left > and the meshing tooth edge 3121 of the 5th right meshing tooth block 312 and the ratchet block 20 The occlusion is achieved to achieve the one-way positioning effect, so that the ratchet block 20 can only rotate counterclockwise when it is applied. 'When the switching handle 332' is pulled and the steel ball 3352 is limited to the U3 (four), the steel ball 3352 will lie against the right 4-tooth block 312, and the 5 H δ Hai left 4-tooth block 311 is yawed to the right, thereby The edge 3111 of the left ring gear 311 and the ratchet 21_ of the ratchet block 2G are engaged to achieve a one-way clamping effect, and the ratchet block 2G can only be rotated clockwise when it is in a fairy. The characteristics of this creation and its expected efficacies are stated as follows: Buben creation is made by integrating the meshing block group. The left and right twisting tooth blocks can be synchronously rotated about the pivoting shaft, and the elastic abutting member is abutted against the meshing tooth block group by rotating the reversing block to further make the left and right meshing teeth The block can selectively mesh with the ratchet block, and at the same time, because the action of the left and right meshing blocks is true, it is not easy to be damaged. 2. The creation has a large force area due to the pressure groove. The reverse force generated between the meshing block group and the ratchet block can be dispersed, and the ratchet wrench can have a longer service life. In summary, the creation has excellent progress in the same kind of products. In fact, at the same time, the technical information about such structures at home and abroad is circulated. The same or similar structure exists in the literature. Therefore, this creation has already possessed the patent requirements and applied in accordance with the law. However, the above-mentioned ones are only one of the preferred and feasible embodiments of this creation. 7 M360112 ^ tc The application of this creation specification and the scope of application for the winter equivalent structural change should be included in the scope of this creation patent.
