[0028] It should be noted that a plurality of rubber bases are provided at the bottom end of the connecting base 1, and a plurality of threaded holes are provided at the top of the connecting base 1 and the lifting platform 402. When the lifting platform 402 falls to the top of the connecting base 1, the operator can insert the bolt column thread through the threaded hole to block and fix the connecting base 1 and the lifting platform 402. The operation requires placing the outer blocks 5 at both ends on both sides of the connecting base 1, and then flipping the upper enclosure 502 through the hinge seat 501. Finally, the connecting blocks 6 of the multiple upper enclosures 502 are connected to each other, and then threadedly connected through the fixing bolts 603.

[0029] Specifically, a plurality of lower hanging ears 203 are provided at the top of the connecting base 1, a plurality of upper hanging ears 202 are provided at the bottom end of the lifting platform 402, the bottom end of the inner scissors frame 201 is hinged to the top end of the lower hanging ears 203, the top end of the outer scissors frame 2 is hinged to the bottom end of the upper hanging ears 202, the top end of the inner scissors frame 201 is provided with an upper slider 4, and the bottom end of the outer scissors frame 2 is provided with a lower slider 401.

[0030] It should be noted that the inner scissor frame 201 and the outer scissor frame 2 refer to the lifting part of the hydraulic lifting platform 402 with model MJ-A1001. When the operator starts the hydraulic rod 3, the hydraulic rod 3 pushes the inner scissor frame 201 and the outer scissor frame 2 to flip. The bottom end of the inner scissor frame 201 will flip with the lower lifting ear 203 as the center, and the outer scissor frame 2 will flip with the upper lifting ear 202 as the center.

[0031] Specifically, the top end of the upper slider 4 is slidably connected to the bottom end of the lifting platform 402 , and the bottom end of the lower slider 401 is slidably connected to the top end of the connecting base 1 .

[0032] It should be noted that when the inner scissors frame 201 and the outer scissors frame 2 are flipped, the top of the inner scissors frame 201 will slide on the bottom end of the lifting platform 402 through the upper slider 4, and the bottom end of the outer scissors frame 2 will slide on the top end of the connecting base 1 through the lower slider 401.

[0033] Specifically, a connecting rod 303 is provided on the outer wall of the outer scissors frame 2 and at one end close to the hydraulic rod 3, a rotating rod 301 is provided in the middle of the inner wall of the inner scissors frame 201, and a connecting ear 302 is provided on the outer wall of the rotating rod 301. The bottom end of the hydraulic rod 3 is fixedly connected to the top end of the connecting rod 303, and the output end of the hydraulic rod 3 is hinged to the inner wall of the connecting ear 302.

[0034] It should be noted that the outer scissors frame 2 is connected to the middle part of the inner wall of the inner scissors frame 201 by a connecting rod 303. When the inner scissors frame 201 and the outer scissors frame 2 are flipped, the inner scissors frame 201 and the outer scissors frame 2 will realize synchronous movement under the connection of the connecting rod 303, so that the lifting of the lifting platform 402 maintains horizontal movement. When the hydraulic rod 3 is started, the hydraulic rod 3 will push the connecting rod 303 through the connecting ear 302, so that the connecting rod 303 drives the inner scissors frame 201 to flip, and at the same time, the rotating rod 301 will drive the outer scissors frame 2 to flip synchronously.

[0035] Specifically, the positioning portion 7 includes a positioning pin 701 and a positioning groove 702. The outer wall of the positioning pin 701 is sleeved with the inner wall of the positioning groove 702. Multiple positioning pins 701 are arranged at the connection of multiple connecting blocks 6. Multiple upper threaded holes 601 are arranged at the top of multiple connecting blocks 6. The bottom end of the connecting block 6 is provided with a lower threaded hole 602. The lower threaded hole 602 is connected to the upper threaded hole 601. The bottom end of the fixing bolt 603 is threadedly matched with the lower threaded hole 602.

[0036] It should be noted that when connecting the upper enclosure 502, the connecting blocks 6 of the upper enclosure 502 need to be horizontally docked, one of the connecting blocks 6 is shaped like an "L", and the other connecting block 6 is shaped like an inverted "L". Multiple positioning pins 701 are set at the protruding ends of the multiple connecting blocks 6, and multiple positioning grooves 702 are set at the recessed positions of the multiple connecting blocks 6. When the multiple positioning pins 701 are mounted on the inner wall of the positioning groove 702, the lower threaded hole 602 and the upper threaded hole 601 will be connected through, and the operator can thread the multiple fixing bolts 603 into the connection between the multiple lower threaded holes 602 and the upper threaded holes 601 to achieve fixation.

[0037] Working principle of this utility model:

[0038] The specific operation is that the operator needs to move multiple outer blocks 5 to both sides of the lifting platform 402, then rotate the upper block 502 with the hinge seat 501 as the center, rotate the upper block 502 to a position perpendicular to the outer block 5, and dock the connecting blocks 6 of multiple upper blocks 502 with each other. When docking, the positioning pin 701 needs to be sleeved on the inner wall of the positioning groove 702, so that the upper threaded hole 601 and the lower threaded hole 602 are connected, and finally the fixing bolt 603 is threadedly matched with the inner wall of the upper threaded hole 601 and the lower threaded hole 602 to achieve The upper enclosure 502 is fixed therebetween. After installation, the operator can start the hydraulic rod 3, and the hydraulic rod 3 will push the rotating rod 301. The rotating rod 301 is forced to push the outer scissor frame 2 to rotate, and the inner scissor frame 201 will rotate in the opposite direction with the lower lifting ear 203 as the center. When the outer scissor frame 2 and the inner scissor frame 201 rotate, the upper slider 4 and the lower slider 401 will be driven to slide at the top of the connection base 1 and the bottom of the lifting platform 402, so that the top of the outer scissor frame 2 and the inner scissor frame 201 rises and pushes the lifting platform 402 to rise, thereby realizing the work of lifting and transporting materials.
