Thus, the pipe connecting disc 21 is fixedly connected to the ram connecting disc 22. The bottom of the ram connecting disc 22 is fixedly connected to one end of the vibrating head 24 close to the ram connecting disc 22. One side of the pipe connecting disc 21 away from the ram connecting disc 22 is fixedly connected to the bottom of the connecting cylinder 25. A vertically penetrating through-hole is provided in the middle of the first limiting disc 26.

The inner part of the vertical groove 214 is slidably connected to the outer wall of the sliding buckle 215. The side of the sliding buckle 215 away from the external sleeve 212 is fixedly connected to the upper end of the inner wall of the protection cylinder 216, so that the protection cylinder 216 is slidably connected to the external sleeve 212 through the sliding buckle 215 and the vertical groove 214. The outer wall of the first limiting disc 26 is attached to the inner wall of the protection cylinder 216, so that the first limiting disc 26 is slidably connected to the protection cylinder 216.

The other end of the clamping rod 217 away from the sliding bar 213 movably penetrates through the side wall of the clamping through hole 221. A plurality of clamping plates 219 are vertically provided on the side wall of the clamping through hole 221, so as to limit the sliding bar 213 through the clamping plates 219.

[0033] The implementation principle of a concrete vibrating rod with an anti - shedding structure in an embodiment of the present application is as follows: The operator holds the grip 222 and then starts the vibrating operation. When the vibrating operation is carried out, the vibrating tube 1 will drive the tube connection disk 21 to vibrate. The tube connection disk 21 drives the ram connection disk 22 to vibrate through the screw 23. The screw 23 will drive the vibrating head 24 to vibrate, thereby vibrating the concrete. When the vibrating head 24 vibrates, it will generate a vertical reciprocating vibration. The tube connection disk 21 will drive the connecting cylinder 25 to move upward. The connecting cylinder 25 will drive the first limiting disk 26 to move vertically upward. The first limiting disk 26 will compress the first spring 27, thereby reducing the vibration for the first time through the first spring 27. The connecting cylinder 25 will also drive the connecting ring 29 to move upward. The connecting ring 29 will drive the second spring 210 to be compressed, thereby buffering the vibration for the second time through the second spring 210, so as to offset the vertical movement of the vibrating head 24. When it is necessary to vibrate concrete with different compactness, the operator pulls the limit buckle 218, so that the clamping rod 217 is disengaged from the clamping plate 219. Then the sliding bar 213 is slid, so that the sliding bar 213 drives the third limiting disk 211 to slide vertically, compressing the return spring 220. Then, when it moves to the appropriate position, the limit buckle 218 is released. The clamping rod 217 moves horizontally toward the clamping through - hole 221 under the push of the return spring 220 and is clamped with the clamping plate 219, so as to be clamped with the clamping through - hole 221 again, limiting the sliding bar 213, thereby reducing the distance between the third limiting disk 211 and the connecting ring 29, making the counter - buffering performance of the second spring 210 stronger, so as to offset the stronger reverse vibration caused by the increase in the compactness of the concrete.

[0034] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
