The spring 101 is sleeved on the surface of the lock cylinder 82 and is located between the pad 103 and the fixing tube 102.

[0043] In this embodiment, the elastic compression force of the spring 101 is used to press against the surface of the pad 103, which in turn presses against the surface of the universal ball 9, so that the universal ball 9 can be just locked in place, resulting in a simple structure.

[0044] Specifically, the locking device 8 further includes a positioning shaft 83 and a ball bearing 84. The positioning shaft 83 is mounted on the surface of the locking plate 81, and a groove 85 is formed on the surface of the positioning shaft 83. The ball bearing 84 is mounted on the surface of the universal ball 9.

[0045] In this embodiment, under normal circumstances, the lock cylinder 82 is in a horizontal state. When the drawer plate 4 is installed from the guide rail assembly 6 onto the surface of the vibrating top plate 2, the groove 85 on the surface of the positioning shaft 83 just locks the ball 84. This indicates that the drawer plate 4 is installed in place, reducing the risk of dangerous situations and making the drawer plate 4 more stable when vibrating.

[0046] Specifically, the handle 17 has a groove 12 inside, the lock cylinder 82 is installed inside the groove 12, and the handle 17 and the lock cylinder 82 are matched in shape.

[0047] In this embodiment, the lock cylinder 82 can slide inside the slide groove 12 of the handle 17. On the one hand, the handle 17 protects the lock cylinder 82 from accidental contact, and on the other hand, it facilitates the operation of locking the lock cylinder 82 with the vibrating top plate 2.

[0048] Specifically, a torsion spring 13 is fitted onto the surface of the roller 7, with one end of the torsion spring 13 mounted on the surface of the handle 17 and the other end of the torsion spring 13 mounted on the surface of the drawer panel 4.

[0049] In this embodiment, the torsion spring 13 is normally positioned so that the handle 17 is in a horizontal state, which makes it convenient to pull the entire drawer plate 4 out from the surface of the vibrating top plate 2 by operating the handle 17.

[0050] Specifically, the surface of the handle 17 is provided with a mounting groove 14, and one end of the torsion spring 13 is inserted into the interior of the mounting groove 14.

[0051] In this embodiment, the torsion spring 13 is easy to install and remove.

[0052] Specifically, the guide rail assembly 6 includes a guide groove 61 and a guide rod 62. The guide groove 61 is installed on the surface of the vibrating top plate 2, and the guide rod 62 is installed inside the drawer plate 4.

[0053] In this embodiment, the guide rail assembly 6 is used to make the drawer plate 4 move along the axial direction of the guide groove 61 and the guide rod 62 to prevent it from deviating.

[0054] Specifically, a retaining strip 15 is installed on the surface of the drawer panel 4, the fixing plate 5 is inserted into the retaining strip 15, and a fixing device 16 is provided between the fixing plate 5 and the handle 17.

[0055] In this embodiment, the fixing plate 5 is secured to the surface of the drawer plate 4 using the clip 15, and a fixing device 16 is used to prevent the fixing plate 5 from falling off.

[0056] Specifically, the fixing device 16 includes a pin 161 and a slot 162. The slot 162 is formed on the surface of the fixing plate 5, and the pin 161 is fixed to the surface of the handle 17.

[0057] In this embodiment, when the lock cylinder 82 drives the pin 161 on the handle 17 to rotate, the pin 161 is locked inside the slot 162, which not only makes it convenient to fix the fixing plate 5, but also makes it convenient to replace the fixing plate 5.

[0058] The working principle and usage process of this invention: In normal state, the handle 17 and the lock cylinder 82 are always in a horizontal state under the action of the torsion spring 13. At this time, the fixing plate 5 is installed on the surface of the drawer plate 4, and the drawer plate 4 is moved along the direction of the guide rod 62 until the groove 85 on the positioning shaft 83 locks the ball 84. At this time, it is difficult to turn the handle 17, and the surface drawer plate 4 has been installed in place. Then, hold the handle 17 and apply pressure to the lock cylinder 82. At this time, the spring 101 is stretched, and the universal ball 9 moves closer to the handle 17. Then turn the entire handle 17 and release it. Under the rebound action of the spring 101, the universal ball 9 is locked inside the circular groove 11. At this time, the torsion spring 13 is in a state of applying external force, and the pin 161 on the back is locked inside the slot 162, which fixes the fixing plate 5 firmly. If the fixing plate 5 needs to be replaced, it can be replaced in time when unlocking.
