The bottom surface of the extension plate 2 is fixed, and a groove 3 is provided at the center of the lower end of each extension plate 2. A pressing plate 4 is telescopically connected in each groove 3. The bottom surface of each pressing plate 4 abuts against a guide plate 5. The two guide plates 5 are movably connected to the bottom surface of the table body 1. A second sliding groove is horizontally provided on the top surface of each guide plate 5.

Two second electric push rods 10 are horizontally fixed on the side surface of each guide plate 5. The two second electric push rods 10 are horizontally fixed to the bottom surface of the table body 1.
[0023] By using the guide block 12, the guide groove 11 and the rotating shaft 13 on the top surface of the table body 1 to move; connecting two left and right mirror-symmetrical extension plates 2, and driving the two extension plates 2 to move through the second electric push rod 10 and each guide plate 5, the length of the table body 1 can be rotated and adjusted, so that the table body 1 can be placed in spaces of different sizes;
[0024] Reference Figure 1 , Figure 2 and Figure 4 In order to achieve the purpose of fixing the rotation angle of the extension plate 2, two front and rear mirror-symmetrical receiving grooves 14 are vertically opened on the top wall of the groove 3, a spring 15 is vertically fixed in each receiving groove 14, a guide rod 18 is fixed at the end of each spring 15, and the guide rod 18 is axially slidably connected in the receiving groove 14, and two radially symmetrical first sliding grooves 16 are vertically opened in each receiving groove 14, a first sliding block 17 is slidably connected in each first sliding groove 16, a guide rod 18 is commonly fixed between every two first sliding blocks 17, and a pressing plate 4 is commonly fixed at the ends of every two guide rods 18, and two mirror-symmetrical positioning grooves 19 are vertically opened on the top surface of each guide plate 5, and a positioning block 20 is axially inserted in each positioning groove 19, and the positioning block 20 is vertically fixed to the bottom surface of the pressing plate 4;
[0025] By opening a groove 3 at the end of the extension plate 2, a pressing plate 4 is movably connected in the groove 3 through the receiving groove 14, the guide rod 18 and the spring 15, and the pressing plate 4 is connected to the top surface of the guide plate 5 through the positioning block 20 and the positioning groove 19, so that the rotation direction of the extension plate 2 can be limited, and the extension plate 2 is prevented from rotating by itself when the table body 1 is used;
[0026] Reference Figure 1 and Figure 2 In order to facilitate the transportation of the table body 1, two first electric push rods 6 with front and rear mirror symmetry are vertically fixed on the bottom surface of each guide plate 5, a support plate 7 is fixed to the end of each first electric push rod 6, and a universal wheel 8 is movably connected to the bottom surface of each support plate 7. By arranging the universal wheel 8 on the bottom surface of the guide plate 5, the entire table body 1 can be transported and moved, and there is no need for multiple people to lift the table body 1 together and then carry it together, which reduces the effort spent on transporting the table body 1.
[0027] Working principle: When in use, the second electric push rod 10 pushes the two guide plates 5 to move in the opposite direction, and the guide plates 5 drive the two extension plates 2 to move in the opposite direction, so that the overall length of the table body 1 increases until it moves to the required length, and then the pressing plate 4 is lifted up, and the guide rod 18 rises toward the storage groove 14, so that the spring 15 is compressed, the pressing plate 4 is separated from the guide plate 5, and the positioning block 20 falls off the positioning groove 19, and then the extension plate 2 is driven to rotate to the required angle through the rotating shaft 13 rotatably connected to the guide block 12, and then the pressing plate 4 is released, and the compressed spring 15 is reset. When the spring 15 is reset, the guide rod 18 is pushed out of the storage groove 14, and the guide rod 18 drives the pressure plate 4 to descend, so that the positioning block 20 on the pressure plate 4 abuts against the ground, and the rotation position of the extension plate 2 is limited. When the table body 1 needs to be moved, the first electric push rod 6 drives the support plate 7 to descend, and the support plate 7 drives the universal wheel 8 in a suspended state to descend, so that the universal wheel 8 contacts the ground, and the support leg 9 is in a suspended state. Then, by pushing the table body 1, the table body 1 moves smoothly driven by the universal wheel 8. After moving to the desired position, the first electric push rod 6 retracts the universal wheel 8, so that the universal wheel 8 is in a suspended state, and the support leg 9 contacts the ground.
