New Description: [New Technology Field] This creation is about the improvement of a telescopic structure of a hand tool, especially a ratchet wheel with an eccentricity pivoting on the body of the wrench to fix the length of the wrench body and the cup. The telescopic structure of the hand tool that does not come loose is improved. [Prior Art] According to the 'hand tool is an extension of human hands, it is an indispensable role in human work. The development of hand tools has been obvious for nearly a hundred years. This can be obtained from the quantity and quality of hand-applied patents. Knowing that in modern times, because of the high wages of labor, any repair work is the most cost-effective, which is why the DIY hand tool market is so large, and the hand tools are divided into several types according to the use efficiency, such as The most widely used wrench tools are open-end wrenches, socket wrenches, plum-shaped ratchet wrenches with hexagonal holes or dodecagonal holes, etc. Users need to use appropriate hand tools to suit their needs. . The above-mentioned hand tools can be referred to the Patent No. 450181 of China, "Stretching Positioning Structure of Powerful Socket Wrench". The hand tool is mainly composed of a wrench body and a sleeve sleeve, and a steering joint is arranged at the front end of the wrench body. The sleeve is sleeved, and the rear portion of the wrench body is provided with a positioning structure. When the sleeve is stretched, the positioning structure is used to maintain the tensile relationship between the sleeve and the wrench body, and the positioning of the rear portion of the wrench body is provided. The slot and the post are so that when the sleeve is rotated, the post is forced to be laterally offset and tightly clamped between the inner wall of the sleeve and the positioning slot, so that the sleeve is restrained and the condensation cannot be operated to maintain the sleeve. Positioning relationship with the wrench body, and the positioning structure of the wrench body is mainly provided with a slot in the vicinity of the rear end of the socket wrench body, so that a spring and a pressing block group M319126 are disposed after the missing slot (4) and forced to reach The front side edges of the block are respectively formed with appropriate oblique sills, and the position of the front end of the slabs of the slabs of the slabs is the same as that of the slanting surface of the slanting sizing of the slabs 'According to the ring slope of (4) When the spanner body is in the back section, the spring will force the block to the outside _, and in the state of forcibly reducing the front side of the restricted rib sleeve, the yoke ring is yawed and the sleeve is slanted.抵, (4) The rear side edge of the block is just opposite to the rear end of the slot, so that the positioning performance of the tight (four) is achieved, and the problem of structural damage and the escape of the sleeve is avoided. . However, the above-mentioned hand tool uses a post-clamping card to abut between the inner wall of the sleeve and the positioning notch, so that the sleeve can be restrained and the condensation cannot be operated, so as to maintain the positioning relationship between the sleeve and the wrench body, but the column is easy to loosen. , resulting in difficulty in positioning between the sleeve and the handle body. [New content] Therefore, in view of the fact that the above-mentioned hand tools are easy to loosen due to the above-mentioned hand tools, the positioning relationship between the sleeve and the wrench body is not stable enough, so in the spirit and concept of appealing for progress, and with the help of many years of accumulation With the help of professional knowledge, technology and experience, we are constantly striving for improvement and development. Therefore, we have created a ratchet that has an eccentric pivot on the body of the wrench to fix the length of the wrench body and the sleeve without loosening. Structural improvement. The hand tool of the present invention has an improved telescopic structure, and the main body of the wrench body has a pivoting piece formed at one end of the wrench body to pivotally connect a steering joint, and the other end of the wrench body is eccentrically pivoted with a ratchet wheel. Sawtooth, and a notch is formed in the ratchet body near the ratchet, and a slot is formed in the bottom of the notch to provide a resilient element, and a pressing block is arranged on the slot to press against the elastic component, and then the wrench body The outer sleeve is set with M319126 dry* top pressure on the pressing block, and the end of the sleeve is combined with a nut, and a convex ring is formed at the inner wall of the screw to abut against the side wall of the pressing block; The friction between the inner wall of the cup and the serration of the ratchet is used to fix the length of the wrench. The only need to rotate the sleeve is to make the inner wall of the sleeve more tightly contact with the ratchet without loosening. [Embodiment]: For the purpose of making the technical content, the purpose of creation and the effect of the achievement of this creation more clear and clear, please elaborate below, and please refer to the illustrated figure and Figure: First, please refer to the first figure.
