Description of the Invention: [Technical Field] The present invention relates to a hand tool such as a screwdriver, and more particularly to a connecting rod with a sleeve. [Prior Art] The fifth figure shows a conventional hand tool connecting rod 9 including a rod body 90 and a sleeve 91. The rod 90 is tightly implanted into the sleeve 91 so that the two can be tightly coupled without being arbitrarily separated. In the case of using such a hand tool connecting rod 9 to loosen or tighten a screw, the body 90 is used to connect a convenient torque applying tool, and the sleeve is used to connect a tool head, for example The cross-starting head, the word-starter head, in this case, the sleeve 91 and the rod body 90 are substantially in a state of relative torsion and respectively bear the same magnitude but opposite directions of force. The hand tool connecting rod 9 and its application For further reference to Taiwan's announcements M28_, M295564, 48 Dragon, 47844〇 and other patent cases. - Let the body 9Q be closely implanted with the sleeve 9. The sleeve 91 needs to have a circular r ^ circular groove 910, and the outer diameter of the circular groove 910 needs to be slightly smaller than the body g The lower part of the dry plating of the crucible is 9〇1, and the M280891 lucky towel f + i is placed in the circular groove 91〇 where the rod body 90 is upright. 5 200948546, the top surface of the rod 90 is stamped to force the lower jaw portion 901 of the rod 9 into the circular groove 910, as shown in the seventh figure. Further, the work of closely fitting the rod 90 into the sleeve 91 is completed. Ο ❹ It can be clearly seen in the eighth figure that each corner of the lower portion 901 of the rod 9 都是 is an acute angle and is trapped in the inner wall of the circular groove 910 of the sleeve, so that the circular groove 91 is 〇 The inner wall is formed with a corresponding recess 912. This is a result of forcing the lower portion of the rod 9 to be inserted into the circular groove 91 of the sleeve 91. Note that the sides of the lower portion 9〇1 of the rod body 90 are not in contact with the inner wall of the circular groove 910 of the sleeve 91. Therefore, in the case where the hand tool connecting rod 9 is used to loosen or tighten a screw, all the torque is concentrated on each corner of the lower portion 9G1, and the groove on the inner wall of the circular groove 910. 912. Such a concentrated torsion force causes the corners of the lower portion 9〇1 to concentrate on pushing the corresponding grooves 912, so that the grooves 912 are quickly enlarged, thereby causing the rod 90 to Loose. Although the publication No. 2 8 0 8 91 further mentions the use of a buckle to limit the axial displacement of the rod 9 但这, but this can only avoid the rod 90 falling off, can not overcome the above loose problem. In addition, the lower portion 9〇1 of the rod body 90 is a hexagonal column, and the circular groove (4) of the sleeve 91 is not easy to be concentrically positioned due to the difference in shape. This makes the lower portion 9 〇 ι may not be the problem of insufficient concentricity after the second body 9q is assembled with the sleeve. SUMMARY OF THE INVENTION The present invention provides a new hand tool connecting rod that includes a rod and a sleeve. The correction has a connecting segment, a polygonal segment following the connecting segment, and a cylindrical segment following the polygonal segment. The sleeve has a polygonal groove and a cylindrical groove that continues one of the polygonal grooves. The polygonal slot receives the polygonal segment of the shank and its inner wall abuts against the perimeter of the polygonal segment. The cylindrical channel receives the cylindrical section of the body and tightly engages the cylindrical section. Preferably, an annular groove is formed on the surface of the cylindrical portion of the rod, and a convex portion is formed on the inner wall of the cylindrical groove to extend into the annular groove. This projection can be used to further ensure that the rod does not fall off the sleeve. In the present invention, by the feature that the inner wall of the polygonal groove of the sleeve is attached to each side of the polygonal section, the problem that the rod of the conventional hand tool connecting rod is easily loosened can be solved. By the fact that the cylindrical groove of the sleeve and the cylindrical section of the rod are both circular, it is possible to overcome the problem that the concentricity of the rod and the sleeve of the conventional hand tool connecting rod is not 7 200948546 . V\ [Embodiment] The first to third figures show a preferred example of the hand tool connecting rod of the present invention. The first figure shows that the hand tool connecting rod includes a rod body 10 and a sleeve 20, but the rod body 10 has not been implanted into the sleeve 2〇. The second and third figures show that the rod 1 has been implanted into the sleeve 2〇.

J shows in the first and second figures that the rod 1 has been implanted in the sleeve 20. The rod 10 is implanted into the sleeve 2 in a punching manner. As shown in the third figure, by pressing the force, the cylindrical section 12 of the cup 10 can be forced into the cylindrical groove 22 of the sleeve 2, which causes the cylindrical section 12 to be the cylindrical groove. 22 tightly grips the entire shank 10 and thus does not detach from the sleeve 2 。. If desired, the outer diameter of the polygonal groove 21 of the sleeve 2 can also be made slightly smaller than the outer diameter of the polygonal section u of the shaft 10. Thus, by the force of the punching, the polygonal section U of the rod body 1 can also be forced into the polygonal groove 21 of the sleeve 20, so that the polygonal groove 21 is fastened to the polygonal section u. This can be advanced to ensure that the rod does not disengage from the sleeve 20. Referring to the third figure, in the cylindrical groove 22 of the cylindrical section _ domain sleeve 20 of the rod body 1G, since the cylindrical groove 22 has a smaller inner diameter, the cylindrical section 12 is The portion that is urged to the inner wall of the cylindrical groove 22 to be pushed will flow into the annular groove 13 on the cylindrical section 12 depending on the material ductility. This is equivalent to forming a plurality of projections 22 on the inner wall of the cylindrical groove 22, and the I portions 220 project into the corresponding annular grooves 13, thereby having the effect of further axially displacement of the cylindrical section 12 by 200948546. $ means, this hair,: the sun and the moon can ensure the rod in the H step without the buckle. The body will not be detached from the sleeve 20. It can be clearly seen in the fourth figure that each side of the polygonal section ^ of the rod body 1 abuts against the inner wall of the sleeve 2〇, so when the rod body 1U cylinder 20 bears T-torque force, The torsion is the inner wall surface of each of the polygonal segments u that are dispersed to the rod body ίο corresponding to the sleeve 2G, instead of being concentrated at each corner of the polygonal section u of the rod body 10 and the sleeve 20 The corresponding (four) face. Therefore, the problem of the looseness of the body of the connecting rod is known and is present in the present invention. In addition, in the present day, since the cylindrical groove 22 of the sleeve 20 and the cylindrical section 12 of the rod 1 are round, it is easy to align to a concentric position, so the rod body and The concentricity of the sleeve 20 after assembly can be greatly improved, thereby solving the problem that the conventional hand tool has insufficient concentricity between the rod and the sleeve of the cup. Anyway, 'anyone can get enough guidance from the above descriptions' and understand that the invention has indeed met the requirements of the invention patent, and the application is made according to law. 200948546 [Simple Description of the Drawings] -»··································· The second figure shows a perspective combination of the preferred embodiment.
