[0027] When in use, the travel trolley 2 moves inside the track slide rail. When the end beam body 1 and the travel trolley 2 are disassembled, the block 13 is rotated to make the block 13 leave the slot, so that the contraction spring 15 is stretched by force, and then the push block 11 is pressed downward to make the push block 11 drive the connecting rod 10, the guide ring 9 and the positioning slide block 12 to move, so that the guide ring 9 slides along the length direction of the guide rod 4 to play a guiding role. The end of the positioning slide block 12 is located inside the positioning slide groove. The movement of the positioning slide block 12 provides a component force in the horizontal direction for the support rod 8, and the end of the T-shaped slide block 7 is located inside the T-shaped slide groove, so that the support rod 8 drives the trapezoidal block 5, the limit block 6 and the T-shaped slide block 7 to move, so that the limit spring 3 is contracted by force, and the T-shaped slide block 7 slides along the length direction of the T-shaped slide groove. Slide to make the limit block 6 leave the limit groove, then move the end beam body 1 upward to make the positioning block 23 disengage from the positioning groove, which is convenient for the disassembly between the end beam body 1 and the travel trolley 2. Conversely, during installation, the end of the positioning block 23 is inserted into the interior of the positioning groove. When the top of the positioning block 23 reaches the end of the positioning groove, the limit block 6 is aligned with the limit groove. The push block 11 is released, and the elastic tension of the limit spring 3 is used to make the trapezoidal block 5 drive the limit block 6 to reset, so that the end of the limit block 6 is inserted into the interior of the limit groove, and the positioning slider 12 drives the push block 11 to reset, and the clamping block 13 is released. The elastic contraction force of the contraction spring 15 is used to reset the clamping block 13 into the interior of the clamping groove, which is convenient for limiting the position of the push block 11 and improving the stability of the installation connection.
