[0037] The hose connector 3 includes a left mounting head 31, a hose 32 and a right mounting head 33. The left mounting head 31 is connected to the left joint connecting pipe 2, the right mounting head 33 is connected to the right joint connecting pipe 4, and the hose 32 is connected between the left mounting head 31 and the right mounting head 33.

[0038] The right joint connecting pipe 4 is provided with a moving groove 11, and the elastic pin 7 can be elastically moved in the moving groove 11, so as to facilitate the movement of the elastic pin.

[0039] A limiting slot block 12 is provided on the right joint connecting pipe 4 , and the elastic needle spring 8 is connected in the limiting slot block 12 .

[0040] The right joint connecting pipe 4 is provided with a limiting groove 13 and a limiting column 14, the limiting groove 13 is provided with a limiting hole 15, the elastic pin 7 is located in the limiting groove 13 and extends out of the limiting hole 15 to limit the elastic pin.

[0041] The cross section of the elastic needle 7 is U-shaped, so that the elastic needle can be moved up, down, left, and right to a certain extent by pushing the elastic needle button.

[0042] The left and right joint connecting pipes 2 and 5 are both provided with connecting posts 16, and the left and right joint bases 1 and 5 are both provided with connecting grooves 17, and the connecting posts 16 are connected to the connecting grooves 17 accordingly, thereby improving the stability of the connection between the left joint connecting pipe and the left joint base, and between the right joint connecting pipe and the right joint base.

[0043] The inner side wall of the ejection needle button 9 is tilted inwards, and the inner side wall of the ejection needle button 9 matches the outer side wall of the right joint connecting pipe 4. This allows the ejection needle button to move outward and downward to a certain extent, making it convenient for the ejection needle to escape from the locking groove.

[0044] A button 18 is provided at the bottom of the right joint seat 5. A spring is provided inside the button 18. A clamping block 20 is provided on the button 18. A clamping slot 19 is provided at the bottom of the left joint seat 1. The clamping block 20 is correspondingly clamped into the clamping slot 19. When folding is required, one only needs to press the spring-loaded end of the button, so that the clamping block at the other end of the button moves outward under the influence of the spring, so that the clamping block is disengaged from the clamping slot. Then, the left connector and the left joint connecting pipe are rotated and bent along the rotating shaft cover. The hose between the left joint connecting pipe and the right joint connecting pipe is stretched. When the locking groove on the left joint connecting pipe is clamped in the locking groove on the spring pin, the folding pipe joint is automatically locked.

[0045] Working principle: The right connecting tube is formed by installing the right joint connecting tube on the right joint seat, and the left connecting tube is installed on the left joint seat to form the left connecting tube. Both the left connecting tube and the right connecting tube are rotatably connected to the rotating shaft cover. A button slot is provided at the bottom of the right connecting tube, and a button is provided in the button slot. A card block is provided on the button, and the card block is correspondingly connected to the card slot on the left joint seat. A spring pin is provided on the right joint connecting tube, and there is a locking slot on the spring pin. When the vacuum cleaner is used, you only need to press one end of the button with a spring so that the card block at the other end of the button moves outward under the influence of the spring so that the card block is disengaged from the card slot, and then the left connector and the left joint connecting tube are rotated and bent along the rotating shaft cover. The hose between the left joint connecting tube and the right joint connecting tube is stretched, and when the locking slot on the left joint connecting tube is stuck in the locking slot on the spring pin, the folding tube joint is automatically locked. When it needs to be opened, you only need to push the spring pin button so that the spring pin is disengaged from the locking slot. This structure facilitates the automatic locking and opening of the folding tube. When it is not needed, it can be folded to save placement space.
