Description of the Invention [Technical Fields According to the Invention] The present invention and the manual: such as a screwdriver and an electric moving tool have: :::: the species can withstand a large torque without collapse. [Prior Art] Sixth The figure shows a conventional hand 纟 (such as a screwdriver, etc. 主要# is mainly formed at the end of the rod body 5 integrally formed - plastic grip 6. In order to avoid the rod body 5 is detached from the grip β, in the ^ Before the handle 6 is shot and formed, the two flaps 50 are first punched out on both sides of the rod body 5, and then the handle 6 is wrapped around the two flaps 5. However, the rod body 5 is punched out. When the two flaps are 5 〇, the structure of the #5 body is destroyed, and the structural strength thereof is reduced. In addition, the grip 6 is rotated by the rod body 5 (such as screws: bolts, etc.) When the torque is received by the two fins 50, the two flaps 50 are the ones punched out from both sides of the rod 5, and the tensile strength is (4). Therefore, the two wings are large when the torque is large. The film of the series is very easy to collapse. Taiwan Patent No. M280894 shows a multi-purpose /, head, and, structure. The grip portion of the body 1 is integral with the jaws of one end. Therefore, the jaw joint of the 201010833 which the jaws cooperate with the lock 11 can only be used on the hand tool body 1, and no, the method is used. Others, such as a power tool or a pneumatic tool, etc. The invention provides a hand tool comprising a rod body and a handle. The cup body has a polygonal shape, and a ring on the circumference of the rod body has a ring. a groove having a groove and a stopper, the groove being polygonal and correspondingly accommodating the rod, wherein the block is positioned in the groove for snapping into the groove. The structural design of the rod body and the recessed groove in a polygonal shape is such that the rod body can withstand a large torque without collapse, and the structure in which the ring member is inserted into the ring groove is more The hand tool of the present invention further comprises a chuck disposed at one end of the body for holding a tool head. The chuck has a body and a body. The clip has a plurality of jaws at one end, and the jaws are enclosed The clamping space is for accommodating a tool head. The sleeve system is sleeved on the clamping jaws, and the sleeve body is movable on the clamping jaws to interlock the clamping jaws to clamp or loosen a tool head. The invention further provides a clamping head The hand tool comprises a collet and a rod body. The collet has a clamping body and a set body, and the clamping body has a plurality of clamping jaws at one end. The clamping jaws enclose a clamping space for accommodating a 201010833 tool. a sleeve, the sleeve is sleeved on the jaws, and the sleeve is movable on the jaws to interlock the jaws to clamp or loosen the tool, the head. The rod system extends from the body and is a polygonal shape, and the rod system is detachably inserted into a groove of a sleeve, and has a ring groove on a circumferential surface of the rod body for engaging a stopper in the groove. Thus, the rod body is polygonal The design is capable of withstanding large torques without collapse. Moreover, the rod body is detachably inserted into the structure of the 套筒 sleeve, and is more suitable for mounting on various driving tools such as a grip, a power tool or a pneumatic tool. In addition, the use of the chuck can achieve the purpose of quick disassembly and assembly of the tool head. [Embodiment] The second figure shows a first embodiment of the hand tool of the present invention. The hand tool includes a chuck 1 and a rod 2. Wherein: the chuck 1 comprises a body 1 and a set of bodies 11. The collet 11 has four claws 12' which define a clamping space between the four jaws 12 for receiving the tool head A. The end of each of the jaws 12 has an outer bevel 13 on the outer peripheral wall of each of the jaws 12 and has an outer threaded section 14. The inner wall of the casing u has an inner bevel 15 at the opening near one end, and has an internally threaded section 16 on the inner wall. The sleeve u is sleeved on the four claws 12, 201010833 and the externally threaded section 14 and the internal thread section 16 are screwed together. The sleeve can be moved over the four jaws 12 by the screwing of the externally threaded section 14 and the internally threaded section 16 such that the inner ramp 15 presses or disengages the outer ramp 13. The rod body 2 has a hexagonal shape and extends from the body 1 , and has a ring groove 2 on the circumferential surface of the rod body 2. In the second drawing, it is pointed out that when the inner inclined surface 15 of the casing 11 presses against the outer inclined surface 13 of the four jaws 12, the ends of the four jaws 12 are inwardly contracted to clamp the The tool head a; when the inner inclined surface 15 of the sleeve 11 is separated from the outer inclined surface 13 of the four jaws 12, the terminal ends of the four jaws 12 are restored to their original positions by their own elastic force, Tool head A. This allows the tool head A to be quickly disassembled. The fourth figure shows an embodiment of the first embodiment of the present invention. It is noted that the hand tool of the first embodiment of the present invention is separably coupled to a sleeve 4 of a driving tool 4 (e.g., a grip, a power tool, an air tool). The sleeve 4 has a slot 41 and a striker 42. The recessed groove 41 has a polygonal shape for the rod body 2 to be detachably inserted. The blocking member 42 is located in the recessed groove 41 and can be engaged in the annular groove 2 of the rod body 2. By virtue of the polygonal design of the rod body 2, when it is inserted into the recessed groove 41 of the sleeve 40, it can withstand a large torque and does not collapse. 201010833 • However, the cup body 2 can be inserted separately The structure of the sleeve is further adapted to be mounted on various driving tools 4. In addition, the engagement of the stopper 42 into the annular groove 20 prevents the rod 2 from being detached from the groove 41. The fifth embodiment is a second embodiment of the present invention, and the structure of the hand tool mainly includes an integrally injection molded plastic material grip 3 as compared with the first embodiment. The handle 3 has a recess 3 〇 and a stop ❹ 31. The recess 30 is located at one end of the handle 3 and is hexagonal for accommodating the rod 2. The blocking member 22 is located in the recessed groove 30 and can be engaged with the annular groove 20 of the rod body 2. By the structure in which the rod body 2 and the king polygon of the recessed groove 41 are embedded, the rod body 2 can be subjected to a large torque without collapsing. Moreover, the engagement of the stopper 31 into the groove 20 prevents the rod body 2 from being detached from the groove 3. In any event, anyone can obtain sufficient instruction from the description of the above examples, and it is understood that the present invention is indeed different from the prior art and has industrial applicability and progressiveness. 201010833 [Simplified illustration of the drawings] Fig. 1 is an exploded view of the first embodiment of the present invention.
