The outer right side of the rotating shaft 33 is threaded with a nut 37. During operation, the vertical sleeve 11 is supported by the inclined sleeve 31 and the inclined support rod 32. The inclined support rod 32 can slide inside the inclined sleeve 31 through the cooperation of the telescopic groove 34, the nut 36, and the threaded rotating shaft 35. This allows the inclined sleeve 31 and the inclined support rod 32 to meet more support requirements. At the same time, the inclined sleeve 31 is installed with the vertical sleeve 11 through the threaded rotating shaft 33, the nut 37, and the vertical sleeve 11. Therefore, the inclined sleeve 31 is easy to install and disassemble, and the inclined sleeve 31 and the inclined support rod 32 are easy to disassemble and transport.

[0030] The rear surface of the horizontal sleeve 23 and the rear surface of the horizontal bar 27 are respectively attached to the front surfaces of the two vertical sleeves 11. The left side of the oblique sleeve 31 is attached to the right side of the vertical sleeve 11. The buckle 4 is set in an elastic arc shape. During operation, it is convenient for the buckle 4 to install and remove the water pipe 5. At the same time, the horizontal sleeve 23 and the oblique sleeve 31 can be disassembled and transported with the vertical sleeve 11.

[0031] Example 2: Figures 4 to 6 As shown in the comparative embodiment one, another embodiment of the present invention further includes two leveling components 6, which are respectively disposed at the bottom of two vertical sleeve rods 11. Each leveling component 6 includes a threaded hole 61 at the bottom of the vertical sleeve rod 11, and an adjusting screw 62 is threadedly connected inside the threaded hole 61. A support plate 63 is fixedly connected to the bottom end of the adjusting screw 62, and a support pad 64 is fixedly connected to the bottom of the support plate 63. During operation, the adjusting screw 62 is rotated and moves within the threaded hole 61. The rotation of the adjusting screw 62 can drive the support plate 63 and the support pad 64 to rotate and move. Therefore, when the placement surfaces of the two vertical sleeve rods 11 are uneven, the height of the support plate 63 and the support pad 64 can be adjusted to keep the two vertical sleeve rods 11 level, thus preventing the device from being unstable and avoiding accidents during water spraying that could affect the device's performance. This allows the device to meet more usage requirements.

[0032] It also includes two limiting components 7, which are disposed between the vertical sleeve rod 11 and the diagonal sleeve rod 31. Each limiting component 7 includes a fixing block 73 fixedly connected to the bottom of the diagonal sleeve rod 31. The bottom of the fixing block 73 has a through groove 74. A limiting rod 72 is rotatably connected inside the groove 74 via a rotating rod 75. A limiting bolt 71 passes through the lower part of the limiting rod 72. The left end of the limiting bolt 71 is inserted into the vertical sleeve rod 11, and the limiting bolt 71 is threadedly connected to the vertical sleeve rod 11. During operation, the combination of the limiting rod 72, the fixing block 73, and the limiting bolt 71 keeps the diagonal sleeve rod 31 and the vertical sleeve rod 31 in a straight line. The inclined sleeve rod 31 and the vertical sleeve rod 11 are limited together, and when the device is in use, the inclined sleeve rod 31 and the vertical sleeve rod 11 remain stable. The inclined sleeve rod 31 will not cause unstable support to the vertical sleeve rod 11 due to accidental rotation. At the same time, the limiting rod 72 can be easily disassembled and installed by the limiting bolt 71. The rotation of the limiting rod 72 and the fixing block 73 can facilitate the rotation, storage and position adjustment of the limiting rod 72. When the inclined sleeve rod 31 is at different tilt angles, the limiting rod 72 can also rotate to correspond with the vertical sleeve rod 11. The limiting rod 72 and the vertical sleeve rod 11 are then fixedly installed by the limiting bolt 71, which makes it convenient to use.

[0033] The top end of the limiting rod 72 is located inside the groove 74 and is set in an arc shape. The support pad 64 is made of rubber. During operation, the top end of the limiting rod 72 can rotate inside the groove 74, and it is convenient to rotate and store the limiting rod 72 when the device is disassembled. At the same time, the rubber material of the support pad 64 makes the support pad 64 have a good anti-slip effect with the ground, and makes the support pad 64 have a good support effect, and makes the support pad 64 provide stable support.
