[0024] Specifically, when the curb needs to be carried, first, the carrier lifts the handle 4, then opens two connecting rod two 63, under the elastic force of the damping spring 66, two clamping plates 65 can be tightly attached to the upper corner part of the curb, then the carrier presses the handle 4, the vertical rod 61 will move upwards, when the vertical rod 61 moves upwards, two connecting rod one 62 will move upwards on the side close to each other, and the side far away from each other of two connecting rod one 62 will have an upward pulling force on the side far away from each other above two connecting rod two 63, so that the side far away from each other below two connecting rod two 63 has a tendency to close to each other, so that two clamping plates 65 have a tendency to close to each other, and then two clamping plates 65 can firmly clamp the curb on both sides, then the curb will move upwards synchronously with the vertical rod 61, realizing clamping and hoisting, in this process, the handle 4, the fixed rod 3, the axle 2 and the curb constitute a lever movement, so that the carrier can use small force to clamp and hoist the curb with large volume, thereby reducing the labor intensity, and improving the work efficiency.

[0025] In one embodiment of the utility model, the bearing and towing assembly 7 includes guide pipes 71, sliding pipes 72, supporting arms 73, lifting ropes one 74 and lifting ropes two 75; the guide pipes 71 are provided with two, are fixed on the two side walls of the support rod 5 symmetrically, the sliding pipes 72 are provided with two, are all L-shaped, one end of the two sliding pipes 72 is slidably arranged in the two guide pipes 71, the supporting arms 73 are provided with two, are all L-shaped, one end of the two supporting arms 73 is slidably arranged in the one end of the two sliding pipes 72 away from the guide pipe 71, and the compression spring 721 is connected between each sliding pipe 72 and the support rod 5, the fixed rod 3 is symmetrically fixed with two winding columns 31 on the one end close to the handle bar 4, the support rod 5 is provided with a communication hole, the lifting rope one 74 is provided with two, one end of the two lifting rope one 74 is connected on the side wall of the one end of the two sliding pipes 72 close to each other, the other end is slidably arranged in the communication hole of the support rod 5 and is wound on one of the winding columns 31, the lifting rope two 75 is provided with two, one end of the two lifting rope two 75 is connected on the one end of the two supporting arms 73 away from each other, the other end is slidably arranged in the communication hole of the support rod 5 and is wound on the other winding column 31.

[0026] Specifically, before the curb is lifted, the lifting rope one 74 and the lifting rope two 75 are in a natural relaxed state, that is, when the curb is not lifted, under the resistance of the compression spring 721, the two sliding pipes 72 and the two supporting arms 73 are on the two sides of the curb, and the two supporting arms 73 are in contact with the ground under the action of their own gravity, when the curb is lifted, first pull the two lifting ropes one 74, the two sliding pipes 72 move synchronously into the guide pipe 71, and the compression spring 721 stores energy, when the two sliding pipes 72 drive the lower ends of the two supporting arms 73 to contact each other, that is, the two lifting ropes one 74 cannot be pulled out, the two lifting ropes one 74 are wound on one of the winding columns 31, then the two lifting ropes one 74 are in a tight state, then pull the two lifting ropes two 75, the two supporting arms 73 will move synchronously upwards along the inner wall of the sliding pipe 72, when the lower ends of the two supporting arms 73 contact the bottom of the curb, that is, the two lifting ropes two 75 cannot be pulled out, the two lifting ropes two 75 are wound on the other winding column 31, then the two lifting ropes two 75 are in a tight state, at this time, the two supporting arms 73 can support the bottom of the curb, avoiding the curb from falling due to shaking during transportation, thereby ensuring that the curb can be transported stably.

[0027] In one embodiment of the utility model, rubber pads are installed on the inner walls of the two clamping plates 65, for increasing the contact friction with the curb.

[0028] Specifically, when installing the curb, the carrier first lifts the handle 4, then spreads the two connecting rods two 63, and under the elastic force of the damping spring 66, the two clamping plates 65 can be tightly attached to the upper corner of the curb. Then the carrier presses the handle 4, and the vertical rod 61 will move upwards. When the vertical rod 61 moves upwards, it will have a force on the two connecting rods two 63 to move closer to each other, and this force will firmly hold the curb on both sides through the two clamping plates 65. Then the curb will move upwards synchronously with the vertical rod 61, realizing clamping and lifting. Then pull the two pull ropes one 74, and the two sliding tubes 72 move synchronously into the guide tube 71, while the compression spring 721 stores energy. When the two sliding tubes 72 drive the lower ends of the two supporting arms 73 to contact each other, i.e. the two pull ropes one 74 cannot be pulled out any more, the two pull ropes one 74 are wound on one of the winding columns 31. Then the two pull ropes one 74 are in a tense state. Then pull the two pull ropes two 75, and the two supporting arms 73 move upwards along the inner wall of the sliding tube 72. When the lower ends of the two supporting arms 73 contact the bottom of the curb, i.e. the two pull ropes two 75 cannot be pulled out any more, the two pull ropes two 75 are wound on the other winding column 31. Then the two pull ropes two 75 are in a tense state. Thus the installation of the curb is completed.

[0029] After transportation, the curb needs to be disassembled and placed. First, the pull rope two 75 is untied and released. The two supporting arms 73 move downwards synchronously under the action of their own gravity and are separated from the bottom of the curb. Then the pull rope one 74 is untied and released. The two compression springs 721 release energy, so that the two sliding tubes 72 drive the two supporting arms 73 to move away from each other, and then the two supporting arms 73 move to the two sides of the curb. After that, the handle 4 is lifted, the curb is placed on the ground, and the two clamping plates 65 are removed from the curb. Thus the disassembly and placement work is completed.

[0030] The above is only a preferred embodiment of the present application, and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
