It is further preferable that one locking hole is provided at each end of the lower telescopic tube 520, respectively, an upper locking hole 521 and a lower locking hole 522, wherein the upper locking hole 521 and the lower locking hole 522 are respectively the maximum value and the minimum value of the relative distance between the upper telescopic tube 510 and the lower telescopic tube 520, that is, the length of the lifting rod 500 is the longest when the locking part 550 is inserted into the upper locking hole 521, the folding box 200 is in the unfolded state, and the length of the lifting rod 500 is the shortest when the locking part 550 is inserted into the lower locking hole 522, and the folding box 200 is in the compressed state (storage state).

In this embodiment, the lifting rod 500 operates according to the principle that when the folding box 200 needs to be unfolded, i.e. the state that the locking part 550 is inserted into the lower lock hole 522, at this time, the trigger part 530 is pressed down, the locking part 550 is retracted through the action of the transmission part 540 on the locking part 550, the insertion action between the locking part 550 and the lower lock hole 522 is released, then the supporting frame 240 on the folding box 200 is pulled, so that the folding box 200 is unfolded, and the locking part 550 moves up synchronously with the upper telescopic pipe 510, when the upper telescopic pipe 510 reaches the maximum extension amount, the position of the locking part 550 just corresponds to the position of the upper lock hole 521, at this time, the trigger part 530 is released, so that the locking part 550 is inserted into the upper lock hole 521, and thus the upper telescopic pipe 510 is locked, and the folding box 200 needs to be unfolded, i.e. the state that the locking part 550 is inserted into the upper lock hole 521, at this time, the trigger part 530 is pressed down, the action of the transmission part 540 on the locking part 550 is acted on the locking part 550, so that the locking part 550 is retracted, the insertion action between the locking part 550 and the upper part 521 is released, and then the locking part 550 is pushed up synchronously moves up, when the upper telescopic pipe 510 reaches the maximum extension amount, the position of the upper telescopic pipe 510 is released, and the locking part 200 is compressed, and the position of the upper telescopic pipe is completely retracted, thereby the locking part is completely retracted, and the upper locking part is completely locked, and the upper locking part is completely retracted.

In this embodiment, the lifting rod 500 changes the relative distance between the upper telescopic tube 510 and the lower telescopic tube 520 through the cooperation between the trigger portion 530, the transmission portion 540 and the locking portion 550, so as to realize the unfolding and storage of the folding box 200, which is convenient and reliable to operate.

Further preferably, as shown in fig. 1 to 18, the trigger part 530 includes a pressing cover 531 movably clamped with the supporting frame 240, at least one pair of contact pins 532 are disposed along the edge of the pressing cover 531, wherein a positioning column 533 for nesting the first spring 534 is disposed in the middle of the pressing cover 531, one end of the first spring 534 abuts against the bottom surface of the inner side of the pressing cover 531, and the other end of the first spring 534 abuts against the supporting frame 240. By the compression of the first spring 534, the up-and-down movement of the pressing cover 531 is achieved, and thus the locking and the disengagement between the pressing cover 531 and the supporting frame 240 are achieved.

Further preferably, as shown in fig. 1 to 18, the transmission part 540 includes a rail 541 nested with the positioning column 533, and a slider 542 nested with the rail 541, wherein one end of the slider 542 is engaged with the locking part 550. When the pressing cap 531 is pressed, the first spring 534 is compressed, the rail 541 moves downward in synchronization with the pressing cap 531, and the slider 542 moves downward in synchronization with the rail 541, so as to push the locking portion 550 to retract, and release the insertion between the locking portion 550 and the lock hole.

Further preferably, as shown in fig. 1 to 18, one end of the sliding block 542 is connected with the iron branch 541 in a nested manner, and the other end of the sliding block 542 is provided with a pushing block 543, wherein the end of the pushing block 543 is provided with an inclined surface. In this embodiment, when the slider 542 moves downward, the locking portion 550 cooperating with the slider 542 receives a "pressing force" under the action of the inclined surface of the slider 542, so that the locking portion 550 is "retracted" to unlock the lock hole. In addition, in this unlocking method, stability of the locking portion 550 during movement is improved (since one end of the push block 543 is an inclined surface, a contact manner between the push block 543 and the locking portion 550 is a surface line contact or a surface-surface contact, so that smoothness and smoothness of the locking portion 550 during movement are ensured).

When the slider 542 moves down, the push block 543 pushes the lock tongue 552, so that the second spring 553 compresses, thereby releasing the lock between the lock tongue 552 and the lock hole, and when the slider 542 moves up, the push force of the push block 543 to the lock tongue 552 is released, so that the second spring 553 rebounds, thereby pushing the lock tongue 552 to reinsert into the lock hole.

Further preferably, as shown in fig. 1 to 18, a square groove 551a is provided along the thickness direction of the lock base 551, and a channel 551b is provided along the horizontal direction of the lock base 551, wherein the square groove 551a is communicated with the channel 551b, and a slide rail is provided in the channel 551 b. Wherein, the square groove 551a is used as a nesting space for connecting the lock seat 551 with the push block 543, and the channel 551b is used as a sliding space for the lock tongue 552. In this embodiment, the push block 543 is inserted into the square groove 551a and directly acts on the lock tongue 552, the push block 543 presses down, the lock tongue 552 retracts, the push block 543 moves up, and the lock tongue 552 extends.

Further preferably, as shown in fig. 1 to 18, one end of the lock tongue 552 has a columnar structure matched with the lock hole, the other end of the lock tongue 552 is provided with an inclined plane which is matched with the inclined plane of the push block 543, and retraction and extension of the lock tongue 552 are realized by dislocation sliding between the two inclined planes.

Further preferably, as shown in fig. 1 to 18, the locking portion 550 further includes two limiting plates 554, and the two limiting plates 554 are symmetrically disposed, wherein each limiting plate 554 is provided with a bump matched with a sliding groove 551c on the lock seat 551, so as to limit the moving stroke of the sliding block 542, thereby improving the reliability of the lifting rod 500.
