As shown in the drawings, the avoiding position 13 is a half-open groove, and in some embodiments, the avoiding position can also be a hole structure.

[0038] Further, the embodiment also includes a button sleeve 7; since the horizontal pipe 1 is made of aluminum alloy material, the inner edge of the button hole 11 can be relatively sharp, so the button sleeve 7 is used to protect the inner edge of the button hole 11. At the same time, the manufacturer can also design the button sleeve 7 individually, adding design aesthetics to the pull rod handle. The circumferential edge of the button sleeve 7 is provided with a supporting leg 71 for clamping the button sleeve 7 in the button hole 11; the button 6 extends from the horizontal pipe hole 10 into the button sleeve 7.

[0039] Further, the control rod 2 is provided with a limiting groove 22 on the side close to the reset member 4.

[0040] The following briefly describes the use principle of the pull rod handle of the embodiment applied to the pull rod.

[0041] The pull rod handle of the embodiment is fixedly connected with one end of the pull rod vertical rod through the other end of the curved connecting piece 5. The length of the control rod 2 is slightly greater than the cross pipe 1. The pull rod vertical rod comprises a telescopic sub-pipe and a mother pipe. The locking mechanism is fixed in the sub-pipe; the locking mechanism comprises a lock pin that can move forward and backward, a sliding block that can slide up and down, an elastic member, and a conversion mechanism that converts the up-and-down sliding of the sliding block into the forward-and-backward movement of the lock pin. The sub-pipe is also provided with a pressure rod, one end of the pressure rod is drivingly connected with the sliding block, and the other end penetrates through the curved connecting piece 5 and is accommodated in the limiting groove 22 of the control rod. The limiting groove is used to avoid the end of the pressure rod from being separated from the control rod 2, so the limiting groove 22 can be in the form of a U-shaped groove as shown in the drawings, or in other shapes. The button 6 drives the control rod 2 to move up and down, at the same time, drives the sliding block to slide up and down through the pressure rod, and then drives the lock pin to move forward and backward, thereby controlling the telescopic control of the sub-pipe and the mother pipe. For specific principles, please refer to the Chinese Utility Model Patent with the authorization announcement number CN 204091221 U. Of course, in some embodiments, the utility model can also be applied to the pull rod of the soft locking rope.

[0042] Further, the producer can set the length of the cross pipe 1 to adapt to different sizes of the box body or the vehicle body, or set different lengths of the curved connecting piece 5, and replace the curved connecting piece 5 to adapt to different sizes of the box body or the vehicle body. For those skilled in the art, various corresponding changes and deformations can be made according to the above-described technical solutions and concepts, and all these changes and deformations should belong to the protection scope of the utility model claim.
