[0001] The present invention relates to the technical field of suitcases, and in particular to a rotating and unlocking suitcase pull rod. Background Art

[0002] In order to make the suitcase trolley products on the market have the function of stretching and contracting, they all use an additional button design. Pressing the button can unlock it, and lifting the handle can stretch and contract the trolley. However, the raised button will affect the gripping feel when using it, and there is a probability of accidental touch, which may cause the trolley to be accidentally unlocked, and it is also easy to cause problems such as clothes getting caught. At the same time, because there needs to be a place to insert fingers and lift, there must be a groove between the shape of the trolley and the box shell. The groove will occupy part of the space inside the box, and at the same time affect the integrity of the appearance of the trolley case. In addition, a large number of irregular grooves make it easy for the box to accumulate dust when stored, and it is also difficult to clean the dust. Summary of the invention

[0003] The purpose of the present invention is to solve the deficiencies of the prior art and to provide a suitcase in which an integrally rotating pull rod handle is used as a switch for unlocking, retracting and ejecting the pull rod.

[0013] Preferably, the outer surface of the handle upper shell is provided with two avoidance openings, and the avoidance openings are used to avoid the two handle support feet when the handle rotates.

[0014] Compared with the prior art, the technical solution proposed in the present application has the following beneficial effects: the pull rod of the present invention cancels the raised button design on the existing pull rod. The integral rotating pull rod handle is used as a switch for unlocking, retracting and popping out the pull rod. The pull rod can be unlocked and a groove for the hand buckle appears while rotating the pull rod handle. Therefore, there is no need for a groove for the hand buckle and a protrusion of a button in the natural state. While the appearance is neat, the hand buckle position is omitted, and the internal space of the box is increased. Dust is also accumulated only on the flat outer surface of the box, which is convenient for cleaning. At the same time, the problem of accidentally touching the button during use, causing the pull rod to pop out accidentally and hang on clothes, is solved. When the pull rod is pulled out and grasped, there will be no uncomfortable hand feeling due to the protrusion of the button. In addition, since there is a space that can be elastically rotated at the grasping position, the vibration of the box from the ground to the opponent when the suitcase is dragged can be effectively reduced, thereby improving the comfort during dragging.
