The ball core 11 is embedded in the outer sleeve 12, and the ball core 11 and the outer sleeve 12 are in clearance fit. The hanger passes through the mounting hole of the metal joint bearing, so that the metal joint bearing is mounted at the lower end of the hanger.

[0021] The bearing mounting seat comprises an upper seat body 41 and a lower seat body 42. The lower seat body 42 is integrally formed at the lower end of the upper seat body 41. The upper end and the lower end of the upper seat body 41 are both in the shape of a circular ring, and the entire upper seat body 41 is in the shape of an annular step. The upper end and the lower end of the lower seat body 42 are also both in the shape of a circular ring, and the entire lower seat body 42 is also in the shape of an annular step. The upper end of the lower seat body 42 is integrally formed with the lower end of the seat body. The bearing pressing plate comprises a compression ring 51 and a bottom plate 52. The compression ring 51 and the bottom plate 52 are both in the shape of a circular ring, and the bottom plate 52 is integrally formed at the lower end of the compression ring 51.

[0022] The bearing mounting seat is sleeved at the upper end of the metal joint bearing, and the inner side of the upper end of the bearing mounting seat is in abutment with the top of the outer sleeve 12 of the metal joint bearing. The upper end of the bearing pressing plate is sleeved at the lower end of the outer sleeve 12 of the metal joint bearing. Through holes are formed in the upper end of the upper seat body 41 and the bottom plate 52. Bolts pass through the through holes to fixedly connect the bearing mounting seat and the bearing pressing plate together. The bearing mounting seat and the bearing pressing plate wrap the metal joint bearing inside.

[0023] As shown in Figure 1 , Figure 3 and Figure 4As shown, the boom includes a rod body 21, a ring belt 22 and a bottom stop 23. In this embodiment, the rod body 21 is integrally formed by three cylindrical sections, and the outer diameters of the three cylindrical sections increase from top to bottom. The ring belt 22 is annular, and is integrally formed on the rod body 21. The ring belt 22 has a breakage. The rod body 21 further has an inwardly recessed stop groove 24, and the length direction of the stop groove 24 is vertical. The breakage width of the annular groove 25 is equal to the width of the stop groove 24. The rod body 21 has the annular groove 25 at the junction of the middle section and the lower end section, and the annular groove 25 is below the ring belt 22.

[0024] A retreat-stop washer is installed in the annular groove 25. The retreat-stop washer includes a ring body 31, an outer stop piece 32 and an inner stop piece 33. The ring body 31 is annular, the outer stop piece 32 is integrally formed on the outer side of the ring body 31, and the inner stop piece 33 is integrally formed on the inner side of the ring body 31. The vertical section of the inner stop piece 33 is L-shaped. The inner stop piece 33 of the retreat-stop washer is embedded in the stop groove 24 of the rod body 21, and the stop groove 24 limits the inner stop piece 33 to prevent the retreat-stop washer from rotating in the annular groove 25.

[0025] The rod body 21 further has an upper nut 26 and a lower nut 27. The upper end of the ring belt 22 and the rod body 21 are provided with external threads. The upper nut 26 is installed on the upper end of the rod body 21 by thread cooperation, and the lower nut 27 is installed on the ring belt 22 by thread cooperation.
