The baffle 2 and the workbench 1 are both made of insulating materials. The outer wall of the airbag 3 is attached to the baffle 2. The airbag 3 is made of an insulating flexible material and is hollow inside.

[0035] Working principle and usage:

[0036] Step 1: When the student is using the workbench 1, the baffle 2 is located at the initial position, and the top surface of the baffle 2 is flush with the horizontal surface of the workbench 1. The baffle 2 is located between the student and the workbench 1.

[0037] Step 2: When the leakage current sensor or temperature sensor detects an abnormal situation, the controller controls the driving component to drive the baffle 2 to slide upward, and the student's arm leaves the workbench 1 under the push of the baffle 2. Reduce the harm to students caused by short circuit, heating and explosion of electronic components or leakage of lines.

[0038] Step 3: When the baffle 2 slides upward, the linkage assembly drives the airbag 3 to swell and push the student's body away, so that the student is further away from the workbench 1, and the damage to the student caused by short circuit, heating and explosion of electronic components or leakage of circuits is further reduced.

[0039] Step 4: The controller controls the circuit on the workbench 1 to disconnect, further reducing the harm to students caused by short-circuit heating and explosion of electronic components or circuit leakage.

[0040] Step 2, step 3 and step 4 can be performed simultaneously.

[0041] Compared with the prior art, when an electronic component short-circuits, generates heat, explodes, or a circuit leaks, the contact area between the student and the workbench 1 can be pushed away, and the circuit on the workbench 1 can be disconnected, thereby reducing the damage to the student.

[0042] In this embodiment: the driving assembly includes a first cylinder 4 fixedly mounted on the workbench 1 , the output end of the first cylinder 4 is fixedly connected to the side wall of the baffle 2 , and the first cylinder 4 is connected to a negative pressure pump 7 .
