The detachable discharge pipe 1103 can be directly disassembled and replaced by the staff after deformation, which will not affect the normal use of the mixer, thereby improving the working efficiency of the mixer.

[0032] Embodiment 2

[0033] See also Figures 1 to 5 On the basis of the first embodiment, it is further obtained that the adjustment mechanism 2 includes an adjustment component 21, a transmission component 22 and a telescopic component 23, the adjustment component 21 is arranged on the outer ring of the limiting component 13, the transmission component 22 is arranged in the adjustment component 21, and the telescopic component 23 is arranged on the outside of the positioning component 12.

The rotation of the bevel gear ring 2101 drives the plurality of bevel gears 2201 to rotate. The rotation of the bevel gear 2201 drives the threaded barrel 2202 to rotate. The rotation of the threaded barrel 2202 drives the fixed screw 2301 to move outward on the inner ring of the threaded barrel 2202. The fixed screw 2301 moves outward and drives the clamping rod 1201 to move outward through the fixing plate 1202. The plurality of clamping rods 1201 move outward synchronously to disengage from the connection with the protrusion 1104 to release the positioning of the discharge pipe 1103.

[0037] Afterwards, the staff will clamp the new ring 1101 on the outer circle of the discharge port 31, and then the staff will shake the torsion bar 2105 in the opposite direction. The reverse rotation of the torsion bar 2105 drives the multiple clamping rods 1201 to move inward synchronously. The clamping rods 1201 move inward and clamp on the outer side of the protrusion 1104 to complete the positioning of the discharge pipe 1103. At this time, the installation of the new discharge pipe 1103 is completed, and the replacement of the discharge pipe 1103 is completed.
