Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] Example 1

[0028] Reference Figure 1-Figure 2 A hydraulic oscillator that is easy to maintain includes an oscillation shaft 1. The outer sleeve of the oscillation shaft 1 is provided with a sliding sleeve 2. The sleeve 2 is penetrated by a plurality of drainage holes 3. The drainage holes 3 are distributed in a ring array on the sleeve 2. This is the prior art; a connecting pipe 4 is fixedly connected to the sleeve 2, and a connecting shaft 5 is movably connected inside the connecting pipe 4. The connecting shaft 5 is fixedly connected to the shaft end of a motor, and the motor is not shown in the figure.

[0029] A locking groove 9 is provided on the connecting shaft 5, a locking pin 8 which is slidably arranged and can be reset is penetrated on the connecting tube 4, a through hole is penetrated on the connecting tube 4, and the locking pin 8 is slidably connected in the through hole; the locking pin 8 is slidably connected in the locking groove 9 to fix the connecting shaft 5 and the connecting tube 4 together, a connecting block 6 is fixedly connected to the locking pin 8, a spring 7 is fixed on the connecting block 6, the other end of the spring 7 is fixedly connected to the connecting tube 4, and the spring 7 is sleeved on the outside of the locking pin 8.

[0030] When in use, the staff pulls the connecting block 6 by hand so that the locking pin 8 is not located inside the connecting pipe 4, and then puts the connecting pipe 4 on the outside of the connecting shaft 5, and then loosens the locking pin 8. Under the action of the spring 7, the locking pin 8 can be against the outer wall of the connecting shaft 5, and the sleeve 2 is slowly rotated to drive the connecting pipe 4 to rotate. When the locking pin 8 is opposite to the locking groove 9, under the action of the spring 7, the locking pin 8 is stuck in the locking groove 9 to fix the connecting shaft 5 and the sleeve 2 together; when disassembling, the staff pulls the connecting block 6 by hand to disengage the locking pin 8 from the locking groove 9, and the connecting pipe 4 and the connecting shaft 5 can be disassembled to facilitate inspection of the sleeve 2, etc.

[0031] Example 2

[0032] Reference Figure 3, the difference between this embodiment and embodiment 1 is that this embodiment further includes a blocking mechanism, the blocking mechanism includes a bolt 11 threadedly connected in the drain hole 3, a torsion block 10 is fixed on the bolt 11, and a rubber sleeve is fixed on the torsion block 10;

[0033] Since clean water is discharged through the drainage hole 3, the pressure can be released to achieve the reset of the oscillation shaft 1; the drainage holes 3 are blocked or unblocked at equal intervals by the bolts 11, so that the drainage cycle of the drainage holes 3 can be changed, thereby changing the oscillation frequency of the oscillation shaft 1, and the operation is simple.

[0034] Example 3

[0035] Reference Figure 4 , the difference between this embodiment and embodiments 1 and 2 is that this embodiment also includes an anti-loosening mechanism, the anti-loosening mechanism includes a sleeve 16 sliding on the sleeve 2, the sleeve 16 is coaxially arranged with the sleeve 2, the inner wall of the sleeve 16 slides against the outer wall of the torsion block 10, and a locking mechanism for locking the sleeve 16 is installed on the connecting block 6, the locking mechanism includes a first locking hole 14 and a second locking hole 15 arranged through the sleeve 16, and the first locking hole 14 and the second locking hole 15 are distributed along the axial direction of the sleeve 16; a connecting strip 12 is fixed on the connecting block 6, and a locking rod 13 that can slide in the first locking hole 14 and the second locking hole 15 is fixed on the connecting strip 12. When the locking rod 13 is inserted into the first locking hole 14, the sleeve 16 at this time abuts against the plurality of torsion blocks 10, so that the torsion block 10 can be limited so that it will not rotate, thereby preventing the bolt 11 from rotating and thus preventing it from detaching from the drainage hole 3;

[0036] When it is necessary to remove the bolt 11 or install the bolt 11, the staff pulls the connecting block 6 by hand to drive the connecting strip 12 and the locking rod 13 to move up, the locking rod 13 disengages from the first locking hole 14, and then moves the sleeve 16 to make the second locking hole 15 face the locking rod 13, loosens the connecting block 6, and resets the connecting block 6 under the action of the spring 7. The locking rod 13 is inserted into the second locking hole 15 to position the sleeve 16. At this time, the sleeve 16 is detached from the bolt 11 and will not affect its installation or disassembly.
