[0004] In order to achieve the above-mentioned utility model purpose, the technical solutions adopted are as follows:

[0005] A stone hand-held clamp includes a lifting rod, a fixed plate, a support plate and a chuck. The lower end of the lifting rod is connected to the fixed plate, and the two ends of the fixed plate are symmetrically connected to the support plates. An adjustment slot is provided on the support plate along its length. The chuck is an L-shaped structure, and two chucks are symmetrically provided. The two chucks are respectively fixed in the adjustment slots of the corresponding side support plates by fasteners.

[0006] As a further improvement of the present invention, a handle is fixed to the upper end of the lifting rod.

[0007] As a further improvement of the present invention, the fixing plate is hinged to the supporting plate.

[0008] As a further improvement of the present invention, the fastener is a fastening bolt, which passes through the clamp and the adjustment slot in sequence and is threadedly connected to a fastening nut.

[0009] As a further improvement of the present invention, a rubber gasket is provided on the side of the chuck that contacts the stone.

[0010] As a further improvement of the present invention, the chuck is made of patterned steel plate.

[0011] As a further improvement of the present invention, the length of the handle is 200 mm and the diameter is 50 mm, the length of the lifting rod is 600 mm, the thickness of the fixing plate is 5 mm, the length is 150 mm, and the width is 100 mm, the width of the adjustment slot is 10 mm, and the length is 250 mm, and the chuck is made of 30*3 mm angle steel.

[0012] The beneficial effects of the utility model are as follows: the utility model has a simple structure and is easy to carry. It can easily pick up curbstones and stones, which is conducive to improving paving efficiency. The size between the two clamps can be adjusted by moving the fastening bolts to accommodate different types of stones, ensuring improved efficiency in stone handling. The stone is placed between the two clamps and the handle is pulled by hand. The stone can be easily lifted by friction, avoiding direct contact with the stone by hand, which may cause damage to the hands. BRIEF DESCRIPTION OF THE DRAWINGS
