The table body 1 comprises a table plate 101, a backing plate 102 is fixedly installed at the top of the table plate 101, a sliding rail 103 is fixedly installed above the backing plate 102, a placing frame 104 is movably installed inside the sliding rail 103, a ratchet 105 is movably installed at one end of the placing frame 104 through a rotating shaft, a pressing block 106 is movably installed at one end of the placing frame 104, a first connecting rod 107 is fixedly installed at the bottom of the pressing block 106, a first spring 108 is sleeved on the periphery of the first connecting rod 107, a second connecting rod 109 is movably installed at the bottom of the first connecting rod 107 through a rotating shaft, a third connecting rod 110 is movably installed at one end of the second connecting rod 109 through a rotating shaft, a friction block 111 is fixedly installed at one end of the third connecting rod 110, the friction block 111 is in an arc ring shape, the radian of the friction block 111 is equal to that of the ratchet 105, indicator lamps 112 are fixedly installed above the sliding rail 103, the number of the indicator lamps 112 is not less than, the earphone jack 113 is fixedly installed on the side wall of the desk board 101, the wireless signal box 114 is fixedly installed on the side wall of the desk board 101, the fixing plate 115 is fixedly installed above the ratchet wheel 105, the fixing plate 115 is fixedly installed on the inner wall of the placing frame 104 in a welding mode, the baffle 116 is movably installed inside the fixing plate 115 through a rotating shaft, and the second spring 117 is fixedly installed between the left side wall of the baffle 116 and the right side wall of the fixing plate 115.

The partition board 2 comprises an upper partition board 201, the upper partition board 201 penetrates through the table board 101 and extends to the outside of the table board 101, the upper partition board 201 is formed by combining a rectangular board and a corrugated board, a camera 202 is fixedly installed on the side wall of the upper partition board 201, a mirror 203 is fixedly installed on the right side of the camera 202, and a lower partition board 204 is fixedly installed at the bottom of the upper partition board 201.

The electrical components presented in the document are all electrically connected with an external master controller and 220V mains, and the master controller can be a conventional known device controlled by a computer or the like.

The working principle is as follows: when the wireless signal box 114 is used for sending the examination condition of an examinee to a computer where a teacher is located, the teacher can monitor the examination site through the picture shot by the camera 202, when the teacher finds that the examinee has examination violations like cheating, the wireless signal box 114 sends a signal through an internal program in the computer, the wireless signal box 114 receives the signal sent by the computer and lights the indicator lamps 112, the number of the indicator lamps 112 represents the opportunity owned by the examinee in the examination, when the indicator lamps 112 are all lighted, the examinee shows that the examinee has the violation behaviors in the examination for many times, the examination result is invalid, when the examinee takes the examination, the two examinee can be completely separated due to the blocking of the upper partition plate 201 and the lower partition plate 202, so that the two examinee can not see the examination papers of the other party, and the mutual influence between the examinees can be avoided, the corrugated plate at the tail end of the upper partition plate 201 compensates the space of the position, close to the partition plate, of the examinee through the shape of the waves, so that the examinee is prevented from experiencing error in the examination due to the fact that the examinee feels space limitation and the mind state is influenced due to the existence of the partition plate, meanwhile, the scratch paper is wound in the placing frame 104 movably installed inside the sliding rail 103 on the table plate 101, when the examinee uses the scratch paper, due to the fact that arms write, the pressing block 106 is pressed downwards, the first connecting rod 107 is pushed downwards through the pressing block 106, the third connecting rod 110 is pulled backwards through the second connecting rod 109 under the action of the rotating shaft, the friction block 111 is far away from the ratchet wheel, so that the examinee can rotate the ratchet wheel to update the scratch paper, after the arms of the examinee leave the pressing block 106, the pressing block 106 is pushed upwards under the elastic force of the first spring 108, the third connecting rod 110 is pushed forwards through the second connecting rod 109, the friction block 111 is in contact with the ratchet wheel 105 again, when the ratchet wheel 105 rotates, the teeth on the ratchet wheel 105 stir the baffle 116 through rotation, the baffle 116 is under the action of the second spring 117, when the ratchet wheel 116 stops rotating, the baffle 116 is always kept in a vertical state with the fixing plate 115, the ratchet 116 can only rotate forwards to discharge the draft paper, if an examinee wants to rotate the ratchet wheel 116, the fixing plate 115 and the baffle 116 prevent the ratchet wheel 105 from rotating under the common blocking effect, so that the problem that the examinee copies knowledge points on the draft paper and rewinds the draft paper in advance is avoided, cheating is implemented in an examination, when a hearing examination is performed, an earphone for the examination is accessed through the earphone jack 113, and the earphone and the upper baffle 201 are matched with each other to form a relatively independent and quiet space for the examinee to perform the hearing examination better.

To sum up, when an examinee uses the draft paper, the pressing block 106 is pressed down by the arm and the first connecting rod 107 is pushed down, the third connecting rod 110 is pulled back by the second connecting rod 109 under the action of the rotating shaft, the friction block 111 is far away from the ratchet wheel, so that the examinee can rotate the ratchet wheel to refresh the draft paper, when the examinee's arm is separated, the pressing block 106 pushes up, the third connecting rod 110 is pushed forward by the second connecting rod 109 to make the friction block 111 contact with the ratchet wheel 105 again, so that the ratchet wheel 105 cannot rotate, when the ratchet wheel 105 rotates, the baffle 116 is under the action of the second spring 117, when the ratchet wheel 116 stops rotating, the baffle 116 is always kept vertical to the fixing plate 115, so that the ratchet wheel 116 can only discharge the draft paper in the positive rotation, if the examinee wants to rotate the ratchet wheel 116, the fixing plate 115 and the baffle 116 block the ratchet wheel 105 to prevent the ratchet wheel 105 from rotating together, the problem that the examinee copies the knowledge points on the draft paper in advance and rewinds the draft paper is solved, and cheating is implemented in an examination is solved.

In addition, the anti-plagiarism examination table completely separates two examinees due to the blocking of the upper partition board 201 and the lower partition board 202, so that the two examinees cannot see the examination papers of the other examinee, and mutual influence between the examinees is avoided, and the corrugated board at the tail end of the upper partition board 201 compensates the space of the examinee close to the partition board through the corrugated shape, so that the examination error caused by the fact that the examinee feels space limitation due to the existence of the partition board, and the mood is influenced is avoided.
