[0033] In this embodiment, the two rotating rods 301 can be limited by the provided engagement ring 307 and the annular groove 211 to prevent the two rotating rods 301 from falling off the round rod 204 .

[0034] Specifically, the guide assembly 2 also includes two sliding rods 206, two positioning blocks 207, and two positioning springs 208. A sliding groove 205 is provided on one side of the two round rods 204. The two sliding rods 206 are respectively slidably installed in the two sliding grooves 205.

[0038] Working principle: When in use, if it is necessary to grout the gap of the horizontal surface, press the two slide bars 206 at the same time, compress the two positioning springs 208, drive the two positioning blocks 207 to slide close to each other in the two strip grooves 212, respectively, so that the two positioning blocks 207 are separated from two of the positioning grooves 306, and the two rotating rods 301 can be unlocked. At this time, the two rotating rods 301 are rotated downward to drive the collar 302 to rotate downward. The downward rotation of the collar 302 will drive the straight tube 203 to rotate downward and bend the rubber hose 202. When sliding downward, the limit block 210 will slide in the limit groove 308. When the limit block 210 slides to the end of the limit groove 308, the rotating rod 301 reaches the maximum rotation angle. At this time, the other two positioning grooves 306 will just rotate to correspond to the two positioning blocks 207. At this time, the two sliding rods 206 are released, and the two positioning springs 208 will be released and push the two sliding rods 206 to reset, thereby driving the two positioning blocks 207 to engage in the other two positioning grooves 306 respectively, so that the two rotating rods 301 can be locked again, so that the straight tube 203 keeps tilting downward.
