[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description herein is for describing particular embodiments only and is not intended to be limiting of the application. The use herein of the terms "including", "comprising", "having" and the like are meant to encompass the items listed thereafter as well as other items.

[0027] As shown in Figure 1 and Figure 2 The vibration rod comprises a rod body 1 and a cable 2 connected to the rod body 1.

[0028] The transmission assembly of the vibration rod comprises a frame 3, a chain 4, a sprocket 5 and a unilateral bending mechanism. The sprocket 5 is connected to the frame 3. The chain 4 is arranged transversely and the inner end of the chain 4 is engaged with the sprocket 5. The outer end of the chain 4 is fixedly connected to the rod body 1. The unilateral bending mechanism is located at the lower part of the chain 4. Under the action of the unilateral bending mechanism, each link of the chain 4 can be arranged in a straight line in sequence.

[0029] The frame 3 is fixedly connected with a baffle 6. The chain 4 is located between the baffle 6 and the sprocket 5.

[0030] The chain 4 is located between the baffle 6 and the sprocket 5, and the inner end of the chain 4 is engaged with the sprocket 5. Therefore, the chain 4 can be translated under the rotation of the sprocket 5.

[0031] The chain 4 in translation ensures that the lower part of the chain 4 is flush under the action of the unilateral bending mechanism. Therefore, the chain 4 in horizontal and transverse movement can finally drive the rod body 1 to move stably forward and backward.

[0032] The unilateral bending mechanism is a baffle 7 in the form of a sheet. The upper end of the baffle 7 is hinged to a link. The lower end of the baffle 7 has a protruding blocking part 7a. When the blocking parts 7a of two adjacent baffles 7 are in contact, the two adjacent links are kept flush left and right.

[0033] Since the blocking part 7a is located at the lower part of the chain 4, all the links of the chain 4 can be sequentially adhered in a horizontal state. Conversely, the side of the chain 4 without the baffle 7 can be naturally bent.

[0034] A placement channel is formed between the blocking part 7a and the chain 4, and the cable 2 is threaded through the placement channel.

[0035] This structure not only reduces the space occupied by cables, but also improves the compactness of the structure.

[0036] The baffle 6 is located directly below the sprocket 5.

[0037] The blocking part 7a and the baffle 7 are in surface contact.

[0038] The rod 1 is arranged horizontally.

[0039] The upper side of the chain 4 protrudes from the upper part of the rod 1.

[0040] This structure can minimize contact between the sprocket 5 and the rod 1.

[0041] The baffle 6 includes a straight contact portion 6a and an arc-shaped contact portion 6b. The inner end of the contact portion 6a is fixedly connected to the inner end of the contact portion 6b. The sprocket 5 is arranged concentrically with the contact portion 6b and the outer side of the sprocket 5 is adjacent to the contact portion 6b.

[0042] The first contact portion 6a and the second contact portion 6b are an integral structure.

[0043] This structure enables the sprocket 5 to stably drive the chain 4 to translate.

[0044] Because the chain is kept level and even at its bottom by the single-sided bending mechanism during the rotation of the sprocket, the vibrator can move steadily left and right during the movement of the sprocket-driven chain, resulting in high stability during operation.

[0045] Meanwhile, the cable is designed to pass between the chain and the blocking part of the baffle, so the cable is not exposed. Its structure is also relatively compact and has high practical value.

[0046] like Figure 3 As shown, the baffle 7 includes a U-shaped baffle 7b and a baffle 7c. The U-shaped opening of the baffle 7b is fixed to a link of the chain 4. The bottom of the U-shape of the baffle 7b is directly below the link and forms the aforementioned blocking portion 7a. The length of the baffle 7c is the same as that of the baffle 7b. The baffle 7c is located between two adjacent links. The upper part of one end of the baffle 7c is hinged to one of the links, and the upper part of the other end of the baffle 7c is hinged to another adjacent link. When the horizontally arranged chain 4 hangs down naturally, the blocking portion 7a of the baffle 7b contacts the blocking portion 7a of the baffle 7c, ultimately preventing the chain 4 from swinging downwards. At this time, all the links are horizontally aligned. It can be seen that the above structure can effectively enable the chain 4 to move horizontally stably.

[0047] The technical features of the above-described embodiments can be combined in any manner. For the sake of brevity, not all possible combinations are described, but it is understood that the scope of the present specification includes all possible combinations.

[0048] Those skilled in the art should understand that the above embodiments are only used to illustrate the present application, and are not used as a limitation of the present application. Any appropriate changes and modifications made to the above embodiments within the spirit and principles of the present application shall fall within the scope of the present application.
