New description: [New technical field] This creation is about a modified structure of τ type handle, especially a hand tool used for disassembling and locking bolts and nuts in the bottom of the engine and inside the machine. Specifically, the present invention is a whole circumference in which the outer and outer covers are covered by the outer peripheral edge of the base, which not only enhances the overall aesthetic effect, but also ensures that the internal parts do not stick to oil and dirt; and the resistance The component is provided with a metal rectangular piece with a long rectangular shape, which is simple in structure and convenient in assembly, and thus has the economic benefit of reducing cost. [Prior Art] According to the first and second figures, the conventional τ type handle structure mainly includes two side clips (11), and the ratchets are sequentially assembled between the two side clips (11). a sleeve (12), a check pawl block (13), a spacer body (14), a spring piece (15) bent at one end, a washer (16), a T-handle (17), and a plurality of rivets (18); Although it can achieve the purpose of smoothly rotating the bolt or nut during use, it is often caused by the negligence of the stamping or polishing operation, resulting in a sharp edge on the two side clips (11), and the hand of the holder is inadvertently scratched. Because it is used in the bottom of the engine and the inside of the machine for disassembly and locking bolts, it is easy to adhere to oil collapse and dirt and cause malfunction. Therefore, it is necessary for the unemployed to improve the defects. [New content] In view of the shortcomings of the above-mentioned T-type handle structure, the creator has intensively studied and designed it. After many trials and improvements, the author finally has this creation. The main purpose of this creation is to provide a T-shaped handle improved structure. The M293815 is covered with a red outer circumference by the outer edge of the base. Miscellaneous (4) enhances the overall aesthetic power amplifier, and also ensures that the internal parts are not affected by the oil. The erosion or dirt is contaminated; and the resisting piece is set to be long and thin, and the structure is (4), and the assembly is convenient, and accordingly, the principle of economic efficiency of reducing costs is achieved. [Embodiment] In order to achieve the above objectives, the technical means and its functions adopted by the present invention are as follows, and the following is a detailed description of the present invention, so that the reviewing committee can improve the structure of the present creation. Easy to understand. Please refer to the third to fifth figures for the purpose of the creation. The improved structure of the τ type handle is to assemble the ratchet sleeve (22) and the check claw block in sequence inside the base (8). ), the resisting element (24), the washer (25) and the τ-type handle (26) components, the upper and lower sides of which are riveted and fixed by a cover (2Ό and rivet (28), wherein the base (21) - The end of the system is gradually enlarged to be a curved arc-shaped retaining edge (211), and the middle portion is provided with a lower portion (212) and a flange (213) having a thickness lower than the curved retaining edge (2), which is only padded. (212) The side has no twist and the twist is slightly larger than the receiving groove (214) of the resisting element (μ) in the groove (2) 4) for the component to resist the component (24), and the other end has the middle side plug The outer edge (10) of the groove (2) 5), the outer edge of the cuff seat (2)) is covered with the upper and lower cover (9) for the entire circumference, which can enhance the aesthetic effect of (4), and ensure that the internal parts are free from oil collapse and dirt; The resisting member (24) is a metal dome of a long rectangular shape, one end of which is disposed in the receiving groove (2) 4) of the base (2), and the other end pushes against the pawl block (2). Simple structure, Fast and easy together, so it has economic benefits by reducing the cost of. M293815 In summary, the creation of the "τ-type handle improved structure" is not only a new type of space, but also a practical one. In addition to the lack of sweeping, it is still turning to enhance the practical effect.
