New description: ^ [New technical field] % This creation is about a tie rod structure, especially a telescopic rod structure that is arranged on one side of the suitcase and can be telescoped by appropriate operation and control. [Prior Art] Generally, a large-sized suitcase has a large weight and is difficult to handle because it can load a large amount of clothes. Generally, the wheel is arranged on the bottom surface of the box, and the rod is arranged on the box body. By pulling the rod to apply force and the wheel rolling on the ground, the suitcase can be pulled effortlessly. The type of tie rod includes a single pull rod or a double pull rod. For example, a single pull rod can be formed by inserting a pair of pull rods inside a main pull rod. The secondary pull rod can be moved inside the main pull rod, whereby when the auxiliary pull rod is pulled out of the main pull rod, the entire pull rod has a large length, which is suitable for the user to pull to move the suitcase; and the auxiliary pull rod is contracted inside the main rod The length of the entire rod is shortened, and when the suitcase is placed, it does not occupy space. As for the double tie rods, the two single pull rods are arranged in parallel on the side of the suitcase, and the use state is equivalent to that of the single pull rod, so it will not be described again. Although the drawbar has an elongated and contracted design, it is only combined with the primary and secondary tie rods. The drawbar still has a considerable length and volume when it is contracted, and still takes up considerable space when it is housed. [New content] Since the prior art disclosed tie rod structure comprises a combination of two rod bodies and has a large volume after shrinking, which is disadvantageous for collection, the present invention provides an innovative tie rod structure to solve the prior art. Missing M315040 points. The main purpose of this creation is to provide a telescopic pull rod structure for a suitcase, which is formed by a combination of a plurality of rods and can be contracted to the inside of the adjacent rods. Thereby, the length and volume after the tie rods are placed can be minimized, and no excessive space is required. In order to achieve the above purpose and effect, the N-pillar body is connected in series and arranged on the side of the suitcase of the suitcase, wherein N is a natural number not less than 3 and each end of the rod is inserted adjacently One end of the rod body; the uppermost φ rod body is the first rod body, and the bottommost rod body is the Nth rod body. Further, N-1 controllers are respectively arranged at the bottom of the front N-1 body from the top down. Each controller includes a base and a control combination. The controller has a protrusion at the bottom and an accommodating space at the top. The control assembly is installed in the accommodating space, and includes a dial block and a first button. A combination of a block and a second key block. When each of the first key blocks is protruded from the second to the Nth rods which are counted from top to bottom, the N struts cannot be moved relative to each other; when the first controller is pressed When the dial block drives the adjacent first key block to contract, the first rod body can move and contract in the second rod body; the bottom column of the controller at the bottom of the first rod body is pressed at the bottom of the second rod body. When the toggle block of the controller shrinks the adjacent first key block, the restriction between the second rod body and the third rod body is released, so that the first rod body and the second rod can be contracted in the third rod body; According to this operation mode, the front N-1 body can be fully contracted in the Nth rod body, and the second key block of the controller at the bottom of the N-1 arm is protruded and inserted into the Nth rod body. Positioning is formed on it. M315040 * The length of each rod is combined into a rod body, which can reduce the shrinkage effect of the rod to the shortest length and the smallest volume. The following is a description of the objects, functions and structural configurations disclosed in the present application, and is described in detail with reference to the drawings. [Embodiment] Please refer to FIG. 1 , which shows a case (12) of a suitcase (10) disposed on a base (14), and a pull rod (20) extending vertically upwardly in the box body (12) One side. The tie rods (20) are formed by a series of N struts, and are defined as a first rod body (21), a second rod body (22), and an Nth rod body from top to bottom. Where N is a natural number greater than or above 3. Referring to Fig. 2, taking the combination of the first rod body (21) and the second rod body (22) as an example, the first rod body (21) is one end of the second rod body (22). . In design, the outer diameter of the first rod body (21) is slightly smaller than the inner diameter of the second rod body (22), so that the first rod body (21) can be accommodated inside the second rod body (22). Referring to Fig. 3, a controller (30) is provided between the first rod body (21) and the second rod body (22). More specifically, the controller (30) is disposed at the bottom of the first rod body (21) and is placed in the second rod body (22) along with the bottom end of the first rod body (21). The controller described above may be of a known construction or may be referred to the structure shown in Figure 4. The controller (30) includes a base (40) and a control combination (50). The base (40) has an accommodating space (42) at its end, and the control assembly (50) is assembled inside the accommodating space (42). Referring to Figures 4 and 5, the control combination (50) includes a first key block M315040 (51), a second key block (52), a toggle block (53), a first spring (54)', and a second spring (55). The first key block (51) and the second key block (52) are opposite, and the first spring (54) is disposed between the first key block (51) and the second key block (52). The second spring (55) is sleeved in the axial direction of the second key block (52), and the dial block (53) is disposed on the side of the first key block (51). Referring to FIG. 4 and FIG. 6A, when the control combination (50) is installed in the accommodating space (42), the first key block (51) can be protruded, and the dial block (53) is pivoted in the vacant space ( 42) The opposite wall surface and the top surface corresponds to the vacant space (42) Φ an opening (44) of the top surface, such a convex configuration can bud through the opening (44) and press the dial block (53). Referring to FIG. 4 and FIG. 6B, the control unit (50) is further loaded into the accommodating space (42), and a sheet (46) is disposed on the side of the accommodating space (42) to block the second key block (52). And a combination of the second spring (55) while one end of the second spring (55) can rest against the surface of the cover (46). In addition, the sealing piece (46) is provided with a slot (47) corresponding to the second key block (52). The second key block (52) can be threaded out of the slot (47) under appropriate stress conditions. Referring to Figure 6C, the base (40) has a stud (48) at the bottom. Referring also to Figures 4 and 7, a cover set (60) may be provided on the outer wall of the receiving space (42) of the base (40). The above is taken as an example in which the first rod body (21) and the second rod body (22) and the controller (30) positioned between the first rod body (21) and the second rod body (22) are taken. In fact, the creation of this controller - one controller is arranged between adjacent two rods according to the above-mentioned combination. For the operation of this creation, take three rods as an example, such as M315040 • below. Referring to Fig. 8, the bottom of the first rod body (21) is provided with a conventional 'form controller (31) or the controller (30) disclosed in the present invention. The inside of the first body (21) is provided with an operating lever (80) which is telescopically displaceable. One end of the operating lever (80) corresponds to the controller (31) and the other end is pressed by the user. Further, the controller (31) projects into the second rod body (22), and a key block (32) projects through the positioning hole (71) formed on the wall surface of the second rod body (22). Thus, the first rod body (21) and the second rod body (22) cannot be displaced relative to each other. • Referring to Figure 9, the first bump (51) of the controller (30) disposed in the bottom of the second rod (22) is protruded and placed over the third rod (23). In the hole (73), the second rod body (22) and the third rod body (23) cannot move relative to each other. Referring to FIG. 9 again, when the operating lever (80) is pressed to disengage the key block (32) of the controller (31) from the positioning hole (71) above the second rod body (22), the first rod The body (21) can be received in the second rod (22). Referring to Figure 10, when the first rod displacement reaches the bottom of the second rod (22) ® , the key block (32) of the controller (31) extends into the lower positioning hole (72) of the second rod. At this time, the first rod body (21) and the second rod body (23) are incapable of relative movement; and the boss (33) under the controller (31) is pressed at the bottom of the second rod body (22). The dial (53) of the controller (30), the dial block (53) toggles the first key block (51), and the first key block (51) is contracted to withdraw from the third rod body (23). Position the hole (73). Thus, the combination of the first rod body (21) and the second rod body (22) can be retracted into the inside of the third rod body (23). M315040 Please refer to Fig. 11 'When the combination of the first rod (21) and the second rod (22) ... is placed inside the third rod (23)' and the controller (30) moves to the The bottom of the third rod (23) 'the key block (32) of the controller (31) is restricted by the wall of the third rod (23) without protruding 'but the second key block of the controller (31) (52) The projection is formed by positioning a hole (74) under one of the third rods (23). The combination of the first rod body (21) and the second rod body (22) is such that the third rod body (23) cannot be displaced relative to each other. Referring to FIG. 12, when the user presses the operating lever (80), the key block (32) of the control member (31) is contracted away from the positioning hole (72) below the second rod (22). And the first rod body (21) is displaced upward by the elastic restoring force, so that the key block (32) is separated from the second rod body (22), and the second key of the controller (30) The block (52) also departs from the lower positioning hole (74) of the third rod body (23). Therefore, both the first rod body (21) and the second rod body (22) can be displaced upward, thereby achieving the purpose of stretching. The above embodiments are merely illustrative of the techniques of the present invention and their effects, and are not intended to limit the present invention. Anyone who is familiar with this technology can modify and change the above embodiments without violating the technical principles and spirit of the original creation. Therefore, the scope of protection of this creation should be as described later. Listed. [Simple description of the diagram] The first picture is the appearance of the creation.
