At the same time, the buffer structure 7 may also include an elastic column, one end of which is fixedly connected to the rocking board 1, and the other end is fixedly connected to the base, and the middle part of the elastic column produces corresponding deformation to adapt to the oscillation frequency of the rocking board 1. It is worth noting that the buffer structure 7 used to reduce the inertia of the rocking board 1 has various forms, which will not be further described in this application.

[0065] Furthermore, it also includes a reinforcing plate 11 , which is fixedly connected to the second shaft sleeve 22 and the rocking plate 1 . A quick locking mechanism 6 is also provided on the reinforcing plate 11 , and the rocking plate 1 is detachably mounted on the reinforcing plate 11 through the quick locking mechanism 6 .

[0066] In this embodiment, the reinforcing plate 11 enhances the structural strength of the rocking plate 1 and the dual-bearing cam structure 2 to prevent the rocking plate 1 from being separated from the cam motion structure. The rocking plate 1 can be quickly and detachably installed on the reinforcing plate 11 through the quick locking mechanism 6, which is convenient to install and saves time.

[0067] Specifically, the reinforcing plate 11 connects the rocking plate 1 and the dual-bearing cam structure 2, which facilitates the replacement of the rocking plate 1 according to the test scenario and has stronger adaptability. Fig.11 and Fig.12The quick locking mechanism 6 includes a cam shaft 61, a locking buckle 62 and a fixed block 63. The cam shaft 61 is provided with a first rotating portion 611 and a second rotating portion 612 which are not coaxially arranged. The locking buckle 62 is provided with a first cam groove 621. The first rotating portion 611 is suitable for being placed in the first cam groove 621. The fixed block 63 is fixedly installed on the reinforcing plate 11. The fixed block 63 is provided with a second cam groove 631. The second rotating portion 612 is suitable for being placed in the second cam groove 631. The cam shaft 61 is rotated, and the second rotating portion 612 rotates in the second cam groove 631. The first rotating portion 611 rotates eccentrically in the first cam groove 621 and presses the locking buckle 62 close to the rocking plate 1. The locking buckle 62 is provided with a locking portion 622 at one end close to the rocking plate 1. The locking portion 622 is adapted to abut against the upper end surface of the rocking plate 1. It is worth noting that the rocker 1 can be provided with another quick locking mechanism 6 or a locking buckle 62 at the opposite end of the quick locking mechanism 6. The quick locking mechanism 6 at one end can be used for locking and fixing. A silicone shock-absorbing pad can also be provided on the locking portion 622 of the locking buckle 62. The elasticity of the silicone shock-absorbing pad can achieve shock absorption and locking. At the same time, the quick locking mechanism 6 includes but is not limited to this structure, and can also be a bolt fastening device, etc., which is easy to think of by those skilled in the art.

[0068] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred implementations of the utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications should also be regarded as the protection scope of the utility model.
