Description

M255766 IV. Creation Description (1) [Technical Field to which the New Type belongs] This creation is about the improvement of a screwdriver structure, especially a tool structure that can make the clamping more reliable. [Prior art] 5 5 7 3 〇 As previously known, the screwdriver soil reversal structure such as the U.S. patent case is tied to the screw f 3 and the U.S. patent case 5 6 8 5 2 0 4 'its main knot hole and recess The slotted screwdriver has a central hole and two parallel grooves in the body. The built-in enemy system is tangent. A ratchet is placed in the center hole and the grooves 1 and 14 are placed in the grooves and teeth. 5309093 Element 2 supplemented by 55γ and 5685204 are elements 41 and 50. Please refer to the 16th, 3rd, 4th, 5th, and 5685204 figures of the 16th and 5685204. Figures and the seventeenth figure of 5685204, when using its control structure to make One effect. The dagger screwdriver has the ability to rotate the ratchet in the forward and reverse direction. The 8220 patent case is 63988. The positive and reverse rotation of the beauty tool is C 5 5 8 2 0 8 1 0 9 3 and its groove is changed to 2 0 4 in the above. The structure is not shown in the figure; 〇 The grooves in a straight line, as shown in the third picture of the third β 3 8 8 8 2 The two teeth to the pieces shown in the third picture Wu Guo # 利 案 In the number of teeth of the ratchet This country is the same as the 7 specialized offices. 0 5 The case of small profits is the patent case which lies in 9 8 5 8 5 5 The 82 6 8 7 case is also the 5 7 3 parallel fourth 0 8 1

Can have back teeth evening four # ’so at least the effect required when rotating, so the industry has also developed teeth:

92123 丨 Screwdriver.ptd Page 5 M255766 Creation instructions (2) as shown in the figure, and this type of screwdriver has the following shortcomings as in the conventional background: Please refer to Figure 11 of the brother 彳 彳 彳 *, απ λ is like this Second system # (9 2) ::: It is tangent to the central hole system, (") on the grain, it is slightly tangent and also tangential, system # 2) on the structure of the tooth B at the A The curved surface (9 Η, and the tooth at B is also thick in thickness, and the difference between 焉 and 0) drives the tooth (9 2), f Hirota Yu Fang moves 4, the body (work), when ㈣ (") ㈣: Two r moving ratchets ... Loaded, this load is determined by the system * (" ((made by tooth (9 2) ”)" 9 2) The thickness of the tooth at B is greater than the thickness of the fork = Fracture occurs, and after the fracture, it gets stuck in the ratchet (9 = teeth (9 2)), which causes the drive to be unsuccessful: the lack of teeth. G-neck-shaped screws from another-US patent 6 〇 4 7 6 丄 7 As shown in the third figure, the two grooves and the central hole are also tangent. ^, And the mouth structure μ are auxiliary to form an angle less than 180 degrees and greater than 90 degrees, that is, an angle between the two grooves. , This patent case is also structurally equivalent to the above five = ^ It has the same missing form. The Wu Guo patent case is another Wu Guo patent case 6 6 4 4 1 4 7. The surname of this patent case is supplemented by the third picture and the US patent case 6 0 4 7 6 1 7 μ & In May, 丄 f is slightly cypress. Second: the groove and the center hole are also tangent. 'But the two grooves form a small angle, that is, the second tooth also forms less than 90 degrees. This Kui ^ υ The structure has the following defects:

921231 screwdriver.ptd M255766, creation description (3) 1, ratchet, which is the element (20) 2 1) is fastened to the body, which is the element (',, 0chen17 element (2, too true eye, swallow A. 〇) The back side is the length of the book, so that the ratchet foot 1 〇 is greater than the length of the body (1 〇) +)) at the back & it needs to be convex to the body (... back; t: redundant wheel 20) Can be deducted missing. The length of the wheel (20) is longer. Generally speaking, the screwdriver itself (100), the ratchet (20) are not large, which means that the body is large, and the teeth are large (3). When the component (3 5) is not covered with the cover, the element (3 5) is covered in the pot (10), and the ratchet wheel (20) is used again so as not to fall out of the body (, n, ^, so that the teeth (3 0) and ) Control a certain system * (30) and = profit: the effect of the upper cover (3 5 positive and negative reversal, but at this time the screw (2 〇) ° father closed, so it is tested, and the structure needs to be closed, laughed After assembly, it needs to be enabled before leaving the factory, and the cover (3 gf 2) can be used to test the function (30) and the elastomer (33). Indeed, at this time, the movement of the two life positions, so that the forward and reverse rotation of the teeth (... and bullets) ... can be repeated. It is time-consuming and labor-intensive. W J). Many years of experience in manufacturing, production and marketing of the ontology are lacking, so the creator has also accumulated suggestions. ‘Study on the heart, and finally got the creation of this creation. [New content] The reason is that according to this creative system, the screwdriver structure is improved, dan 921231 screwdriver.ptd M255766

To the radiant symmetric two, accommodation 4. Creation instructions (4) The characteristics are in the slot, the angle, and the slot of the baffle; The tooth-top system can be placed on the outside of the body of the internal body, and whether the block is actually on the body. : A body with a receiving hole and a receiving groove; the receiving slot is provided with two parallel sides; a ratchet is provided with a ring on one side and a convex block, and the two tooth ends protrude and fit in the two tooth receiving grooves; A blocking slot is opened on the top, so that the piece is set in the groove. Inside, the ratchet ratchet and the body are made ^ ^ ^ / X is in the same shape. When the tooth is accommodated, the ratchet can be different from the ring. The upper cover of the card end covers the convex groove of the groove and the two teeth. That is, one side of the teeth of the teeth of the ring teeth of the receiving slot and the two receiving wheel can be visually detected. The body is provided with a convex block; the first is a card end that can be accommodated before the ratchet and the system are grooved by the limitation of the piece of the baffle; the second elastic front end is provided with a support piece to limit without falling out of the teeth One clamping end is provided with one receiving tooth, and two elastic systems are provided with perforation. The members of the Bureau and those who are familiar with this art have a complete understanding of the effect of this creation. The structure and organization of this creation are explained in detail with drawings and numbers, but the following are only used to explain this creation. The implementation of 4 cases is not an attempt to restrict the creation in any form, but any modifications or changes made by Fan Zhi in the spirit of the creation should still fall within the protection scope of the creation.

The F music two-pronged embodiment on page 12 is M255766. 4. Creation instructions (9) Change the position i above the groove of the upper cover (50), the main body (i π, 2) and the bump (5 3). (13) The same effect as the receiving hole (^), the receiving slot (12), and the blocking slot. That is, it is located on the same side, and the entire tooth system is the fourth embodiment of this creation when it is implemented. The number of (") < is also four ::: ,, the body (1 0) is the same as the groove. Efficacy. It is said to be radial, and the whole has a thick voice at the time of implementation. 30) B: In addition to the advantages of visual testing and tooth thickness, it also has another advantage: bad, after the most time. The possible cause of damage is to attach to the time of the damage and can be discarded. Today, due to environmental protection to the elastomer (4, the biggest reason for the screwdriver damage is the structure II Uir = (30) collapse ", at this time this creation ) Internal brake I rq, 5 〇) and then visually inspect the body (χ 〇 is Ruda-I «〇) and the elastomer (4 0) as described above, look at the damage:" Second ': Only early pure system is elastic The body (4 〇) can be immediately relocated. Another advantage of the patent fi J: tf. Click on the above-mentioned US patents such as the US 4 7 After disassembling the cover, it is easy to make teeth and elastomers. Both the teeth and the elastomer are considerably smaller in structure than I7 chickens. In summary, this creation has both novel and practical effects, and can improve the shortcomings of s. It is indeed an excellent creation that can meet the requirements of a new type of patent. An application is filed in accordance with the law. Review carefully and say early
