DETAILED DESCRIPTION

[0023] The implementation of the present application will be described by specific embodiments, and those skilled in the art can easily understand other advantages and effects of the present application from the content disclosed in the specification. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0024] Please refer to Figures 1 to 4 The present application provides a simple lifting appliance, which comprises a lifting arm 1 comprising two groups of symmetrically arranged long edges 2, two groups of symmetrically arranged short edges 3 are arranged between the two groups of long edges 2, and a material clamping assembly is symmetrically arranged on the long edge 2. By arranging the two groups of long edges 2 and the two groups of short edges 3 in combination, the lifting arm 1 for lifting is formed, so that the structure of the whole lifting arm 1 is simpler, and the stability of support can be maintained while the quality of the lifting arm 1 is reduced, and the convenience of lifting is improved.

[0025] The material clamping assembly comprises a driving base 4 arranged at the intermediate position of the two groups of long edges 2, and a driving handle 5 is rotatably connected to the driving base 4. The driving handle 5 is rotated by the driving rod 8, so as to cooperate with the connecting rod 7 to pull the hooks 6 at both ends of the long edge 2. The both ends of the long edge 2 are rotatably connected with two groups of hooks 6, and the connecting rod 7 is hinged between the driving handle 5 and the roots of the two groups of hooks 6. The driving base 4 is provided with a driving rod 8. Before lifting, the connecting rod 7 pulls the hooks 6 to rotate inward around the long edge 2, so that the hooks 6 can be in an open state. After the workpiece enters the lifting working surface, the connecting rod 7 pulls the hooks 6 to rotate outward around the long edge 2, so that the hooks 6 can move inward to clamp the workpiece, so as to ensure the stability of the workpiece during lifting.

[0026] The driving base 4 is provided with a driving through hole 9, and the driving handle 5 is arranged outside the driving base 4, so as to improve the connection convenience between the connecting rod 7 and the driving handle 5. The driving rod 8 passes through the driving through hole 9 and is connected to the driving handle 5, and the driving rod 8 is spaced apart from the driving through hole 9. When the driving handle 5 rotates, the driving rod 8 moves in the circumferential direction with the driving handle 5. Therefore, a movement space of the driving rod 8 is left between the driving rod 8 and the driving through hole 9, so as to ensure the movement stability of the driving rod 8.

[0027] The short edge 3 is provided with a hook driving member 10, and a driving connecting rod 11 is arranged between the movable end of the hook driving member 10 and the driving rod 8.

The driving connecting rod 11 is used as a connecting piece between the hook driving member 10 and the driving rod 8, so as to improve the synchronization and stability of the movement of the driving rod 8 with the hook driving member 10.

[0028] The driving handle 5 is provided with a hinge seat 12 at the center, and the connecting rods 7 are symmetrically arranged on both sides of the hinge seat 12 on the driving handle 5, so that when the driving handle 5 rotates around the hinge seat 12, the connecting rods 7 on both sides can drive the hooks 6 to move oppositely, thereby realizing the opening or clamping action of the hooks 6 and ensuring the movement synchronization of the hooks 6 at both ends of the long side 2.

[0029] The hooks 6 are provided with a hook base 13 between the roots and the long side 2, the hook base 13 is rotatably connected with the long side 2, the hook base 13 is provided with a connecting rod base 14, and the connecting rod 7 is rotatably connected with the connecting rod base 14, so that the stability of the connecting rod 7 driving the hook 6 to rotate can be improved by arranging the connecting rod base 14.

[0030] The long side 2 is further provided with a workpiece guide rod 15 at the lower side, and the workpiece guide rod 15 is provided with a guide hose 16 at the bottom, the guide hose 16 is gradually inclined away from the long side 2, and when the lifting arm 1 is moved downward to the lifting working surface, the position of the lifting arm 1 is guided by the workpiece guide rod 15, and the guide hose 16 can avoid damaging the workpiece surface when the workpiece is positioned.

[0031] The long side 2 is provided with a workpiece clamping plate 17 at the bottom of the inner side of the hook 6, and the workpiece clamping plate 17 is an elastic plate, the side workpiece clamping plate 17 can play an auxiliary positioning role, and the positioning stability of the lifting arm 1 before clamping the workpiece is improved.
