[0003] For the existing handle, in order to meet the purpose of lifting express delivery, the pull rope cannot be stretched again after being stuck. Although this method limits the rebound of the pull rope, if you want to change express boxes of different sizes or lift multiple express boxes at the same time, you can only loosen the restriction, retract the pull rope and pull it out again to change express boxes of different sizes. This setting is not only inconvenient to use, but also a single pull rope cannot be used to carry express boxes that are too heavy, otherwise the pull rope will easily break.

[0004] Therefore, how to provide a telescopic handle for carrying and solve the defects of the existing telescopic handles is a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

DETAILED DESCRIPTION

[0043] The following describes the implementation of the present invention through specific embodiments. Those skilled in the art can readily understand the other advantages and benefits of the present invention from the contents disclosed in this specification. Obviously, the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0044] Please refer to Figure 1-Figure 7 Now, a telescopic handle for transport disclosed in the utility model is described. The utility model is composed of ten parts, such as Figure 1 , including a T-shaped drive handle 1, a traction rope 2, a rope winding assembly 3, a linkage gear 4, a cover 5, a return spring 6, a limiting assembly 7, a clockwork spring 8, a mounting shell 9 and a splint 10. The front end of the mounting shell 9 is connected to the cover 5, and the rear of the mounting shell 9 is provided with a splint 10. The rope winding assembly 3 is arranged in pairs and is installed in the mounting shell 9. One end of the traction rope 2 is wound around the rope winding assembly 3, and the other end of the traction rope 2 is connected to the splint 10. The clockwork spring 8 is installed in the rope winding assembly 3, one end of the return spring 6 is installed in the mounting shell 9, and the other end of the return spring 6 is connected to the bottom end of the T-shaped drive handle 1. The linkage gear 4 is installed in the mounting shell 9, and the left side of the linkage gear 4 is meshed with the T-shaped drive handle 1. The limiting assembly 7 is arranged in pairs and is meshed and connected to the upper and lower sides of the linkage gear 4. The limiting assembly 7 is transmission connected in the mounting shell 9.

[0045] When the present invention is in use, two hands grasp the mounting shell 9 and the splint 10 at the same time and pull them to both sides at the same time. At this time, the rope winding assembly 3 rotates, releasing the traction rope 2, so that the distance between the mounting shell 9 and the splint 10 increases. During the rotation of the rope winding assembly 3, the clockwork spring 8 moves and generates a force, which can drive the rope winding assembly 3 to rotate and reset. Then, the mounting shell 9 and the splint 10 are respectively placed at both ends of the express box, and the mounting shell 9 and the splint 10 are slowly brought closer. At this time, the restoring force generated by the clockwork spring 8 will drive the rope winding assembly 3 to rotate in the opposite direction and retract part of the traction rope 2 until the mounting shell 9 and the splint 10 are against the two ends of the express box. At this time, the express box will be clamped under the joint action of the mounting shell 9, the splint 10 and the traction rope 2. Figure 6 As shown, the user only needs to hold the mounting shell 9 to carry the express box. Another way of using the present invention is to press the T-shaped drive handle 1 after a distance is created between the mounting shell 9 and the splint 10. The T-shaped drive handle 1 moves toward the inside of the mounting shell 9, and the second rack 12 moves downward and drives the linkage gear 4 to rotate counterclockwise. The rotation of the linkage gear 4 will drive the two limiting components 7 to move to the left and right sides respectively, and finally the plug 74 will be inserted into the serrated ring to prevent the rotation of the rope winding component 3. When the rope winding component 3 cannot rotate, the distance between the mounting shell 9 and the splint 10 cannot be changed. Because of the setting of the reset spring 6, the user needs to hold the mounting shell 9 all the time and continue to apply pressure to the T-shaped drive handle 1. Then, when pulling up the express box, the knuckles will press against the surface of the express box, and the surface of the other end of the express box will be pressed against the splint 10. In this way, the express box is clamped, and then the wrist can be turned over to lift the express box. Figure 7As shown, during the transport process, the surface of the clamping plate 10 and the four traction ropes 2 will support the express box to prevent it from falling. When the moving rod 14 moves downward, the moving rod 14 will compress the return spring 6 to generate elastic force. When the force applied to the T-shaped drive handle 1 is removed, the elastic force of the return spring 6 will drive the moving rod 14 upward, so that the moving rod 14 returns to its original position, which is convenient for the next use.

[0046] In a specific embodiment, Figure 2 The rope winding assembly 3 includes a card slot 31, a connecting rod 32, an installation slot 33, an insertion rod 34, a first round rod 35 and a second round rod 36.
