Two fixing frames 7 are fixedly connected to the top of the movable plate 2, and a blocking rod 8 is fixedly connected between the two fixing frames 7. The blocking rod 8 is provided to form a block at both ends of the bearing platform, reducing potential safety hazards during construction.

[0028] Please refer to again Figure 1 、 Figure 4 and Figure 5 , an adjustment mechanism for controlling the outward extension or inward contraction of the two movable plates 2 is provided inside the bearing seat 1. The adjustment mechanism includes a bidirectional screw 11 rotatably disposed inside the bearing seat 1. Two sliding rods 12 are threadedly connected to the bidirectional screw 11. The number of sliding rods 12 is two. The bidirectional screw 11 is a screw with two sections of external threads, and the directions of the two sections of external threads are opposite. By rotating the bidirectional screw 11, the two sliding rods 12 move closer to or away from each other. A side groove 21 is formed on one side surface of the movable plate 2, and an inclined groove 22 communicating with the side groove 21 is formed on the top of the movable plate 2. One end of the sliding rod 12 extends into the side groove 21, and a sliding block 13 is fixedly connected to one end of the sliding rod 12. The sliding block 13 slides inside the inclined groove 22. By rotating the bidirectional screw 11 to control the two sliding rods 12 to move closer to each other, under the action of the two groups of sliding blocks 13 pressing the two groups of inclined grooves 22, the two movable plates 2 extend from both ends of the bearing seat 1 to adjust the area of the bearing platform. One end of the bidirectional screw 11 extends to one end of the bearing seat 1, and a handwheel is fixedly connected to one end of the bidirectional screw 11. The handwheel is provided to facilitate driving the bidirectional screw 11 to rotate.

[0029] Please refer to again Figure 1 and Figure 2 , the support mechanism includes support rods 3 hinged to one end of the two movable plates 2. The number of each group of support rods 3 is two, and the two support rods 3 are connected by a connecting rod 4. A fixing bolt 5 is slidably disposed on the movable plate 2, and one end of the fixing bolt 5 is threadedly connected to the connecting rod 4. The connecting rod 4 is provided to connect each group of support rods 3 together. By rotating the support rods 3, the support rods 3 are retracted to the bottom of the bearing platform to reduce the overall floor space of the device, facilitating storage and transportation. By screwing one end of the fixing bolt 5 into the screw hole on the connecting rod 4, the support rods 3 are kept perpendicular to the movable plate 2, restricting the rotation of the support rods 3.

[0030] Please refer to again Figure 1 and Figure 2, the support rod 3 includes a first threaded sleeve 31 and a first threaded rod 32. The first threaded sleeve 31 is hinged to one end of the movable plate 2 through a pin shaft. The first threaded rod 32 is threadedly connected to the inside of the first threaded sleeve 31. The bottom of the first threaded rod 32 is fixedly connected with a bottom plate. By rotating the first threaded rod 32, the first threaded rod 32 extends outward or contracts inward from the inside of the first threaded sleeve 31 to adjust the overall length value of the support rod 3, thereby adjusting the overall height of the device.

[0031] Please refer to again Figure 1 , Figure 2 and Figure 3 , a stabilizer bar 6 is hinged to the bottom of the bearing seat 1 through a pin shaft. A fixed seat 41 is fixedly connected to the connecting rod 4. The other end of the stabilizer bar 6 is detachably connected to the inside of the fixed seat 41 through a bolt. By providing the stabilizer bar 6, the bearing seat 1 and the support mechanism are connected together, improving the stability of the device.

[0032] Working principle: Move the device to a suitable position. By rotating the support rod 3 to make it perpendicular to the movable plate 2, and then by screwing one end of the fixing bolt 5 into the threaded hole on the connecting rod 4 to keep the support rod 3 perpendicular to the movable plate 2 and restrict the rotation of the support rod 3. By rotating the handwheel at one end of the bidirectional screw 11 to drive the bidirectional screw 11 to rotate, the two sliding rods 12 move closer to each other. Under the action of two groups of sliding blocks 13 and two groups of inclined grooves 22, the two movable plates 2 are pushed to extend outward, and the area of the bearing platform is adjusted according to the on-site construction requirements. After adjustment, by rotating the second threaded sleeve 61 to adjust the overall length value of the stabilizer bar 6, put one end of the second threaded sleeve 61 into the inside of the fixed seat 41, and then use a bolt to combine and connect one end of the second threaded sleeve 61 with the fixed seat 41, improving the overall stability of the device.
