The connecting card columns correspond to the positions of the connecting jacks, and a plurality of rubber clamping rings are fixedly installed on the surface of the connecting card columns.

[0012] A method for using a support platform for a towing lift vehicle, the method comprising the following steps:

[0013] After fixing the mounting base plate on the top of the traction lift, lift and rotate the two sets of levers to drive the fixed plug rods to move upward and retract into the corresponding fixed blocks, squeeze the fixed springs to deform, put the supporting base plate on the top of the mounting base plate, make the T-shaped positioning slots at the bottom of the supporting base plate correspond to the positions of the T-shaped positioning strips, push the supporting base plate to slide on the top of the mounting base plate, make the T-shaped positioning slots clamped on the corresponding T-shaped positioning strip surfaces, until the T-shaped positioning strips are fully inserted into the T-shaped positioning slots, make the positions of the fixed blocks correspond to the positions of the fixed plug blocks, rotate the levers in the concave slots, and press the fixed plug rods down to push out the fixed blocks and insert them into the corresponding fixed plug blocks under the rebound action of the fixed springs, so that the supporting base plate is clamped and fixed on the top of the mounting base plate;

After the personnel climb onto the top of the supporting bottom plate, the two sets of push rods are lifted to drive the two sets of clamping plug rods to move up and retract into the corresponding installation grooves, so that the clamping plug rod drives the limit plate to move up inside the installation groove to squeeze the clamping spring to deform, and the two sets of door panels are rotated to close each other until the door panels are tightly attached to the top of the connecting strip so that the position of the clamping plug rod corresponds to the fixed plug hole, and then the push rod is released to press the limit plate down to the top of the installation groove under the rebound action of the clamping spring, driving the clamping plug rod to move down inside the installation groove to push out of the installation groove and insert into the corresponding fixed plug hole, thereby clamping and closing the two sets of door panels on the top of the connecting strip;

[0015] Then, the concave card frame is covered on the top of the contact position of the two sets of door panels, so that the connecting card column at the bottom of the concave card frame corresponds to the position of the connecting socket on the top of the door panel, and the connecting card column is inserted into the corresponding connecting socket to squeeze and deform the rubber clamp ring inside the connecting socket, and the connecting card column is clamped and fixed inside the connecting socket, so that the concave card frame is clamped and fixed on the top of the two sets of door panels, ensuring that the two sets of door panels will not rotate and open at will on one side of the guardrail two, so that people can stand on the top of the supporting bottom plate and move and lift with the traction lifting vehicle to work.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The cam is then pulled upward to move the fixed plug rod upward and retract it into the mounting block, causing the fixed spring to be squeezed and deformed on the surface of the mounting column until the fixed plug rod is completely retracted into the mounting block. The cam is rotated to clamp the top of the concave slot, so that the support base plate is correspondingly covered on the top of the mounting base plate, so that the T-shaped positioning strip on the top of the mounting base plate is inserted into the corresponding T-shaped positioning slot at the bottom of the support base plate, until the support base plate and the mounting base plate are tightly overlapped, so that the positions of the fixed plug block and the fixed plug rod correspond to each other, the cam is rotated to rotate in the concave slot, and under the rebound action of the fixed spring, the fixed plug rod is pressed down to push out the fixed block and insert it into the corresponding fixed plug block, thereby clamping and fixing the support base plate on the top of the mounting base plate, which is convenient for disassembly, maintenance or installation and fixing of the support base plate and the guardrail.

A concave card slot 301 is provided at the central position of the surface of the fixing block 3. Due to the concave card slot 301, the lever 304 is clamped at both ends of the concave card slot 301, so that the fixing plug-in rod 303 will not slide out of the fixing block 3 at will;

[0030] When the locking cam 303 is unlocked, the locking cam 303 is unlocked and the locking cam 303 is unlocked, so that the locking cam 303 can be unlocked when the locking cam 303 is unlocked.

The clamping rod 504 is located at one end of the sliding groove 503 and is symmetrically fixedly installed with a push rod 507, and the push rod 507 extends through the sliding groove 503 to the outside of the door panel 5. By providing the clamping rod 504 and the clamping spring 506, after the door panel 5 moves to the top of the connecting strip 403 and the position of the fixed socket 404 corresponds to the position of the clamping rod 504, the push rod 507 is released and the clamping rod 504 is pressed down and pushed out of the mounting groove 502 and inserted into the corresponding fixed socket 404 under the rebound action of the clamping spring 506, thereby clamping and fixing the door panel 5 on the top of the connecting strip 403.
