The concrete working principle and the beneficial effects of the embodiment are as follows:

the working principle is as follows:

when the auxiliary plate 112 needs to be used, the abutting piece 152 is firstly unscrewed, then the auxiliary plate 112 slides out of the sliding groove, the support rod 15 is opened and inserted into the inserting hole 153, finally the abutting piece 152 is screwed, the support and the fixation of the support rod 15 on the auxiliary plate 112 can be realized, and a worker can place objects such as lunch boxes or water cups on the auxiliary plate 112.

When the use of the sub-plate 112 is not required, the supporting rod 15 is rotated into the receiving groove 13, and the sub-plate 112 is retracted into the sliding groove.

When using the footrests 4, the handles 211 are first turned according to the actual needs of the individual of the student, so that the footrests 4 are raised into position and the footrests 4 can slide freely in the horizontal direction.

When a student has a rest, the student pedals the pedal 4 with feet, by means of friction between the pedal base plate and the clamping groove 61, the pedal 4 swings outwards in the direction away from the sliding plate 321, meanwhile, the left leg 41 swings clockwise around the hinge point in the direction away from the pedal 4, the right leg 41 swings anticlockwise around the hinge point in the direction away from the pedal 4, when the included angle between the pedal 4 and the horizontal plane is 0 degree, the clamping block 4311 on the left leg 41 abuts against the left bulge 52, the spring 4312 compresses towards the groove bottom of the groove 432, the lug is separated from the clamping hole 421, the inner loop bar 43 rotates and descends in the vertical direction until contacting with the ground, the pedal part 443 is pedaled downwards by the feet to enable the abutting part 442 to abut against and be fixed with the outer wall of the outer loop bar 42, and after the pedal 4 is stabilized, the student can place a calling person on the pedal 4 comfortably; the opening of the right leg 41 is the same as the left leg 41.

When the student need be got up pedal 4, at first upwards trample tread portion 443 with the foot, wait to butt portion 442 and overcoat pole 42 outer wall and loosen the back, promote pedal 4 with the foot, make pedal 4 inwards swing towards the direction that is close to slide 321, left side landing leg 41 is around the pin joint counter-clockwise swing towards the direction that is close to pedal 4 simultaneously, right side landing leg 41 is around the pin joint clockwise swing towards the direction that is close to pedal 4, until pedal 4 and slide 321 laminating, left and right sides landing leg 41 and the laminating of slide 321, card strip 62 is fixed with draw-in groove 61 joint, the student can carry out relevant study.

Has the advantages that:

because sliding connection has subplate 112 in mainboard 111, slide subplate 112 in the mainboard 111, and insert in socket 153 branch 15, realize branch 15 tip and socket 153's fixed with supporting piece 152, thereby the place space of desk has been increased, the staff can be under the condition of not clearing up desktop 11, eat on subplate 112, also reduced simultaneously because the space is less to knock into the drinking cup, water spills on the data file and the possibility that the oil water of eating splashes on the data file on mainboard 111.

The support of the sub-plate 112 by the brace 15 is further enhanced by the triangular stabilizing structure formed between the brace 15 inserted into the slot 153 and the legs 12 and the main plate 111.

Through the arrangement of the arc-shaped guide portion 151 at one end of the supporting rod 15 far away from the hinge point, when the supporting rod 15 is inserted into the socket 153, the supporting rod 15 is conveniently inserted into the socket 153 by the guide function of the arc-shaped guide portion 151, and meanwhile, because the side surface of the socket 153 far away from the main plate 111 is arc-shaped, and the guide portion 151 is also arc-shaped, when the supporting rod 15 is inserted into the socket 153, the two arc surfaces are aligned and attached, and the support member 152 is directly screwed to fix the supporting rod 15 and the table leg 12.

Because the pedal 4 can move up and down along the vertical direction and then is fixed, the horizontal direction can move left and right freely, thereby realizing the adjustment of the up-down left-right position of the pedal 4 and enhancing the applicability of the pedal 4.

Due to the arrangement of the gravity ball 7, on one hand, the inner loop bar 43 is accelerated to extend vertically and downwards under the action of the gravity ball 7, and on the other hand, in the process that the supporting leg 41 is retracted, the arc surface of the gravity ball 7 is beneficial to the retraction of the inner loop bar 43.

Since the foothold 4 is deployable and retractable, the foothold 4 reduces the obstruction to the staff.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
