DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-3 A vibrator for engineering use comprises a frame 1, a motor 2 is fixedly connected to the inside of the frame 1, a sleeve 3 is fixedly connected to the side wall of the frame 1, a connecting seat 4 is fixedly connected to the end of the sleeve 3 away from the frame 1, a steel wire rope 5 is penetrated inside the sleeve 3, one end of the steel wire rope 5 is fixedly connected to the output shaft of the motor 2, and a connecting block 6 is fixedly connected to the end of the steel wire rope 5 away from the motor 2, an eccentric rotating rod 7 is arranged inside the connecting block 6, a sleeve 8 is sleeved on the outside of the eccentric rotating rod 7, a bolt 9 is threadedly connected to the connection between the connecting block 6 and the eccentric rotating rod 7, an insert ring 10 is fixedly connected to the end of the sleeve 8, the insert ring 10 is plugged into the inside of the connecting seat 4, a sealing ring 11 is fixedly connected to the inside of the connecting seat 4, and the sealing ring 11 is pressed against the wall of the sleeve 8.

[0021] A groove is provided on the inner wall of the insert ring 10, and a fixing rod 12 is fixedly connected to the inner wall of the groove. A clamping plate 13 and a torsion spring 14 are movably sleeved on the rod wall of the fixing rod 12. One end of the torsion spring 14 is fixedly connected to the inner wall of the clamping plate 13, and the other end of the torsion spring 14 is fixedly connected to the inner wall of the insert ring 10. A fan-shaped groove is provided on the inner wall of the connecting seat 4, and the clamping plate 13 extends to the inside of the fan-shaped groove.
