[0011] Furthermore, a clamping groove is formed inside the sliding clamping seat, and a positioning member is abutted on the clamping groove. At the same time, the positioning member is penetrated and connected by the rope body. The positioning member is used to fix the dragging direction of the rope body. One end of the rope body is connected inside the sliding clamping seat, and the other end is connected to the push rod.

[0012] Further, the rope body is connected inside the sliding clamping seat and is specifically connected to a pulling component arranged inside the sliding clamping seat. The pulling component is movably arranged inside the sliding clamping seat.

[0013] Further, the pulling component includes an abutting portion and a connecting portion for connecting with the rope body. The abutting portion is stuck inside the sliding clamping seat to prevent the pulling component from disengaging from the sliding component.

[0014] Further, a first elastic component for buffering after the rope body is pulled is installed on the connecting portion.

[0015] Further, the first elastic component is a spring, and the spring is wound around the connecting portion.

[0016] Further, the limiting component is connected with a second elastic component for resetting the limiting component.

[0017] Further, the second elastic component is a spring. The limiting component includes a protruding portion and a pushing block, and one end of the spring is wound around the protruding portion.

[0018] Further, a sliding groove is formed on the limiting component, and a locking component which is hinged inside the sliding clamping seat and extends into the sliding groove is arranged in a matching manner. The locking component is used to prevent the limiting component from disengaging from the sliding clamping seat.

[0019] Further, a handle tube sleeve for preventing the push rod from continuously falling when contracting and abutting against the push rod is arranged on the connecting rod.

[0020] The technical solution of the present utility model proposes a trolley with a telescopic handle structure. By setting a trolley with a telescopic handle structure, the push rod and the connecting rod in the handle tube are used as the objects for telescoping. The push rod is movably sleeved outside the connecting rod and can be telescoped on the connecting rod. A limiting hole is formed on the surface of the connecting rod. In addition, there is a sliding clamping seat arranged in the connecting rod. A limiting groove is formed on the surface at the position matching the limiting hole. A limiting component is installed in a matching manner in the limiting groove. The limiting component extends into the limiting groove to contract the handle tube, or penetrates through the limiting hole and the limiting groove and exposes from the limiting hole to clamp the sliding clamping seat at a fixed height on the connecting rod to extend the handle tube. More specifically, there is also a positioning component abutted on the clamping groove of the sliding clamping seat, which is penetrated and connected by a rope body. The positioning component is used to fix the dragging direction of the rope body. An installation part is arranged on the trolley for installing the trolley with a telescopic handle structure. The beneficial effect of the present utility model is to improve the folding effect of the trolley, facilitate folding and is beneficial for users to use. BRIEF DESCRIPTION OF THE DRAWINGS
