[0031] Embodiment 1: In some embodiments, please refer to the Figures 1 - 6 of the specification drawings. A curbstone clamp that is easy to adjust includes a support frame 11. The support frame 11 is of a U-shaped structure. A clamping mechanism 2 for clamping the curbstone 10 is installed at the bottom of the transverse plate body of the support frame 11. The clamping mechanism 2 includes a clamping device 21 and a length adjustment device 22. The clamping device 21 for clamping and fixing the curbstone 10 is arranged at the bottom of the transverse plate body of the support frame 11. The length adjustment device 22 is arranged at both ends of the clamping device 21. By adjusting the length adjustment device 22, the clamping device 21 can clamp curbstones 10 of different models.

[0032] An adjustable push-pull mechanism 3 for pushing the clamp is arranged between the two vertical plate bodies on both sides of the support frame 11. Wheels 12 are rotatably connected to the bottoms of the two vertical plate bodies on both sides of the support frame 11.

[0033] In the present utility model, the construction worker drives the adjustable push-pull mechanism 3 to drive the clamping device 21 to rotate downward around the wheel 12 to the top of the curbstone 10. At this time, the clamping device 21 is attached to the curbstone 10. After the clamping device 21 clamps the curbstone 10, the adjustable push-pull mechanism 3 is driven to drive the clamping device 21 to rotate upward around the wheel 12. The clamping device 21 drives the curbstone 10 to rotate above the wheel 12. At this time, the center of gravity of the curbstone 10, the center of the wheel 12, and the contact point between the wheel 12 and the ground are coplanar. When it is necessary to clamp curbstones 10 of different models, the length adjustment device 22 is adjusted to make the overall length of the clamping device 21 longer or shorter, so that the clamping device 21 can clamp curbstones 10 of different models. Moreover, the adjustable push-pull mechanism 3 adjusts the angle with the ground, thereby adjusting the highest height at the top of the adjustable push-pull mechanism 3.

[0034] In the present utility model, when the clamping device 21 clamps the curbstone 10 above the wheel 12, since the center of gravity of the curbstone 10, the center of the wheel 12, and the contact point between the wheel 12 and the ground are coplanar, during the process of pushing the adjustable push-pull mechanism 3, the construction workers only need to provide a thrust to overcome the friction between the wheel 12 and the ground, avoiding the pressure to maintain the balance of the fixture, reducing the labor intensity, and improving the work efficiency; by adjusting the length adjustment device 22, the clamping device 21 can clamp curbstones 10 of different models without replacing the fixture, which is convenient and fast; by adjusting the angle of the adjustable push-pull mechanism 3, it can adapt to the different height requirements of people of different heights when using this fixture for operation.

[0035] The clamping device 21 includes a fixed frame 211, a mounting block 212, a rotating rod 213, and an L-shaped block 214. The bottom of the transverse plate of the support frame 11 is fixedly connected with the fixed frame 211. The middle of the mounting block 212 is hinged to the bottom of the fixed frame 211. Both ends of the inner side of the mounting block 212 are hinged with a rotating rod 213. The bottom of the end of each rotating rod 213 away from the mounting block 212 is fixedly connected with an L-shaped block 214, and the two L-shaped blocks 214 are symmetrically arranged. Among them, the mounting block 212 is of a U-shaped groove structure and the opening faces downward.

[0036] The length adjustment device 22 includes a through groove 221, a first mounting hole 222, and a bolt 223. A through groove 221 is arranged inside the rotating rod 213. The inner bottom wall of the through groove 221 is provided with first mounting holes 222 arranged in a uniform linear array. The top of the L-shaped block 214 is provided with a first mounting hole 222. The bolt 223 passes through the two first mounting holes 222 in sequence to fixedly connect the rotating rod 213 and the L-shaped block 214.

[0037] In the present utility model, the construction workers drive the adjustable push-pull mechanism 3 to drive the fixed frame 211 to rotate downward around the wheel 12 to the top of the curbstone 10. The bottom of the mounting block 212 fits against the top of the curbstone 10, and the two L-shaped blocks 214 clamp both ends of the curbstone 10; then drive the adjustable push-pull mechanism 3 to drive the fixed frame 211 to rotate upward. The end of the mounting block 212 hinged to the rotating rod 213 moves upward, and the end of the rotating rod 213 away from the mounting block 212 moves downward due to gravity, making the rotating rod 213 in an inclined state, and further making the L-shaped blocks 214 move towards each other to clamp the curbstone 10; then pull the adjustable push-pull mechanism 3 to make the two L-shaped blocks 214 clamp and drive the curbstone 10 to move upward to above the wheel 12. At this time, the center of gravity of the curbstone 10, the center of the wheel 12, and the contact point between the wheel 12 and the ground are coplanar; and the bolt 223 can fixedly connect the rotating rod 213 and the L-shaped block 214 by passing through the two first mounting holes 222 in sequence.

[0038] In the present utility model, two L-shaped blocks 214 are used to clamp and fix the curbstone 10. Since the center of gravity of the curbstone 10, the center of the wheel 12, and the contact point of the wheel 12 with the ground are coplanar, when construction workers perform operations, they only need to provide a thrust force to overcome the frictional force between the wheel 12 and the ground, reducing the labor intensity and improving the work efficiency. The rotating rod 213 is fixedly connected to the L-shaped block 214 through a bolt 223, and the first mounting holes 222 on the L-shaped block 214 are aligned with the first mounting holes 222 at different positions on the rotating rod 213, so that the two L-shaped blocks 214 can clamp and fix curbstones 10 of different models.

The hand-held push frame 31 is of a U-shaped structure. A plurality of mounting components 34 are provided on the vertical plates on both sides of the support frame 11. The bottom of both sides of the hand-held push frame 31 is hinged to the vertical plates on both sides of the support frame 11 through the mounting components 34 at the bottom. One ends of the two connecting rods 32 are respectively connected to two mounting components 34 at the same height. The other ends of the two connecting rods 32 are both provided with relief grooves 33. Both sides of the hand-held push frame 31 respectively pass through the two relief grooves 33, and the inner walls of the two relief grooves 33 are respectively hinged to both sides of the hand-held push frame 31. A grip for easy holding is provided at the upper end of the hand-held push frame 31. Among them, the plurality of mounting components 34 on the vertical plate on the same side of the support frame 11 are arranged in a uniform linear array.

[0040] The mounting component 34 includes two mounting plates 341, a second mounting hole 342, and a bolt 223. The two mounting plates 341 that are symmetric about the left and right are fixedly connected to the vertical plate of the support frame 11. The second mounting holes 342 are provided on both the mounting plate 341 and the end of the connecting rod 32. After inserting the end of the connecting rod 32 between the two mounting plates 341, the connecting rod 32 and the mounting plate 341 are fixedly connected by passing the bolt 223 through the three second mounting holes 342 in sequence. The bottom mounting plate 341 is hinged to the bottom of the hand-held push frame 31.

[0041] In the present utility model, after inserting the end of the connecting rod 32 between the corresponding two mounting plates 341, the mounting plate 341 and the connecting rod 32 are fixedly connected by using a bolt 223, so that a stable triangle is formed between the two ends of the connecting rod 32, the side of the hand-held push frame 31, and the support frame 11, which is convenient for construction workers to push the hand-held push frame 31 to drive the fixture forward or rotate around the wheel 12.
