In addition, today's luggage is pursuing lightweight design. How to reduce the weight of the tie rod and balance the structural strength has become an important issue in the research and development of the industry. [New content] One of the purposes of this creation is to provide a lever for a trunk that avoids discomfort when used by the user. Another object of the present invention is to provide a tie rod for a suitcase that is smooth and streamlined without being easily contaminated. The purpose of this creation is to provide a tie rod for a luggage case that combines light weight and high structural strength. In order to achieve the foregoing disclosure, the tie rod for the luggage provided by the present invention includes a grip and a two-link 'where the grip has two recessed portions at the two ends of the grip, the two links respectively The top end is connected to the two ends of the grip, each of the connecting rods has an axially extending groove respectively connected to the recessed portion of the grip, and the outer peripheral surface of each of the connecting rod ends and the end of the grip The outer peripheral surface is substantially flush. Thereby, the tie rod is smooth and smooth, and is not easy to be contaminated, thereby avoiding the discomfort of the user, and the light weight and high structural strength. [Embodiment] For a better understanding of the features of the present invention, the following description of the preferred embodiment and the accompanying drawings are as follows: The second drawing is a front perspective view of a preferred embodiment of the present invention; A rear perspective view of a preferred embodiment; and a fourth perspective view of an exploded preferred embodiment of the present invention. Referring to Figures 2 to 4, the drawbar 10 for a luggage case provided by a preferred embodiment of the present invention includes a grip 20 and a two link 30. The grip 20 has a transverse portion 21, two upright portions 22 extending downward from the two ends of the laterally extending portion 21, two recessed portions 23 at the two ends 26 of the grip 2, and two plug portions 28 Extending from the two ends 26, respectively. Wherein each recessed area 23 has a longitudinal section 24 located at the upright portion 22, and a transverse section 25 extending laterally from the top end of the longitudinal section 24 and located at the transverse portion 21, the longitudinal section 24 extending in the direction of the connection The axial direction A of the rod 3G is substantially the same, and the recessed portion 23 is formed by the surface of the grip 20 being smoothly inwardly recessed. The two links 30 are respectively connected to the two ends 26 of the grips 20 by their top ends 31. In the embodiment, the top ends 31 of the two links 30 respectively have a set of joints 32' for the grips 20 The insertion portion 28 is inserted; the outer surface of each of the connecting rods is 2 - the concave groove 33 extending in the axial direction A, and the concave portion 23 S of the grip 20 and the outer peripheral surface of the top end 31 of the connecting rod 3 It is substantially flush with the end % end of the grip , and the peripheral surface 27, so that the two connecting rods are connected with the gripper at the surface of the yoke line, which is not only difficult to hide sweat, but also can be avoided by the user. Uncomfortable at the time. f于钱# 3G is made of light-g metal such as |g alloy, titanium alloy, etc., and its own weight P has been phased lightly and the connecting rod 3G is tubular. The connecting rod has a radial 濉_ then has a 35 Therefore, the connecting rod 3 has a higher structural strength under the weight and material condition #; in contrast, since the grip 20 has the recessed portion 23', the structural strength at the end 26 can be increased, (4) The structural strength at which the grip 20 is joined to the connecting rod 20 is further enhanced. In this way, the drawbar of the present invention can be used with less material to have sufficient structural strength, light weight and high structural strength. Based on the spirit of the present invention, the structure of the tie bar 1 亦可 can also be varied in various ways. The shape of the recessed area 23 can be changed, or the recessed area has only # 'longitudinal ^ without transverse section 'the grip 20 and the connecting rod 3〇 can be joined together by other structures, for example, a plug is provided at both ends of the grip for insertion of the two links. Any such structural changes that are easy to think of should be covered by the scope of patent application for this creation.
