The first clamping strip 2 is rotatably connected to the right side of the front end of the top plate 1, and the second clamping strip 3 is rotatably connected to the left side of the front end of the top plate 1. The upper end of the first clamping strip 2 is rotatably connected to one end of the first connecting rod 5, and the upper end of the second clamping strip 3 is rotatably connected to one end of the second connecting rod 4, and the other end of the second connecting rod 4 is rotatably connected to the other end of the first connecting rod 5. The scissor fork assembly is used to clamp and hoist the graphite column, reducing the number of people The operation further improves the hoisting efficiency of the graphite column. By putting the top plate 1 on the graphite column, the angle between the first clamping bar 2 and the first connecting rod 5 at the rotation connection is reduced, and at the same time, the angle between the second clamping bar 3 and the second connecting rod 4 is reduced, and the angle between the second connecting rod 4 and the first connecting rod 5 is increased, so that the lower ends of the first clamping bar 2 and the second clamping bar 3 are opened to each other, and the unloading of the graphite column is realized. A reversing body 7 and a hoisting ring 8 are provided between the two scissor fork assemblies. The reversing body 7 is located below the hoisting ring 8. The front end and the rear end of the hoisting ring 8 are respectively rotatably connected to the connection between the second connecting rod 4 and the first connecting rod 5. The front end and the rear end are rotatably connected with the mounting plates 6 respectively, and the front end and the rear end of the commutator 7 are fixedly connected with the mounting plates 6 respectively. The commutator 7 is fixed by the mounting plates 6 to ensure the firmness of the commutator 7. The mounting plates 6 are rotatably connected with the lifting rings 8 so that the commutator 7 is always in a vertical state to ensure that the commutator 7 can work normally. The device is lifted by the lifting rings 8 so that it can be lifted smoothly. A plurality of connecting rods are fixed respectively between the first clamping bars 2 and the first clamping bars 2 and between the second clamping bars 3 and the second clamping bars 3 of the two scissor-type assemblies. By fixing a plurality of connections therebetween, the firmness between the two scissor-type assemblies is ensured.

[0028] See also Figure 3 , Figure 4 , Figure 5 and Figure 6The upper end of the commutator 7 is fixed with an upper rotating body 701, and a spring seat 703 is fixed on the upper end of the upper rotating body 701. One end of a spring 704 is fixed on the lower end of the spring seat 703. By arranging a spring 704 between the push rod 705 and the spring seat 703, it is beneficial for the spring 704 to recover after being compressed by the push rod 705. The spring 704 pushes the push rod 705 to quickly return to the initial position. The lower end of the commutator 7 is fixed with a lower rotating body 702, and a push rod 705 is fixed on the lower end of the lower rotating body 702. The push rod 705 is engaged with the limiting groove 101. The lower end of the upper rotating body 701 contacts the upper end of the lower rotating body 702 to form a plurality of rotation grooves 707. The upper end of the push rod 705 is fixed with a plurality of protrusions 706 corresponding to the rotation grooves 707 along its circumference. The protrusions 706 are engaged in the rotation grooves 707 to realize the process of the push rod 705 moving up. When the device clamps the graphite column, the scissor assembly contacts and expands with the graphite column, prompting the commutator 7 to move downward, and the push rod 705 moves downward against the top block 102. At this time, the protrusion 706 rotates along the rotating groove 707, and the push rod 705 rises, and the spring 704 is compressed. At this time, after the scissor assembly completely enters the graphite column, the scissor assembly fits the graphite column, and the lower end of the scissor assembly is tightened. At this time, the spring 704 recovers and pushes the push rod 705 to move downward, and the push rod 705 rotates. During hoisting, the hoisting ring 8 is lifted, and the connection between the second connecting rod 4 and the first connecting rod 5 is moved upward. However, since the lower end of the push rod 705 is clamped in the limit groove 101, the upper end of the push rod 705 is clamped at the lowest end of the rotating groove 707, and the push rod 705 will not move, thereby realizing the clamping and hoisting of the graphite column.

[0029] When the utility model is used:

[0030] First, fix the hook of the crane on the lifting ring 8, and lift the device to the designated position by the crane;

[0031] Then, the device is lowered, the scissor assembly contacts and expands with the graphite column, causing the reversing body 7 to move downward, and the push rod 705 moves downward to press against the top block 102. At this time, the protrusion 706 rotates along the rotating groove 707, and the push rod 705 rises, the spring 704 is compressed, and the device continues to fall. After the scissor assembly completely enters the graphite column, the scissor assembly fits the graphite column, and the lower end of the scissor assembly is tightened. At this time, the spring 704 recovers and pushes the push rod 705 to move downward, and the push rod 705 rotates. When hoisting, the hoisting ring 8 is lifted, and the connection between the second connecting rod 4 and the first connecting rod 5 is moved upward. However, since the lower end of the push rod 705 is clamped in the limiting groove 101, the upper end of the push rod 705 is clamped at the lowest end of the rotating groove 707, the push rod 705 will not move, and the graphite column is clamped and hoisted.

[0032] Next, after the graphite column is hoisted to the designated position, the graphite column is dropped and placed at the designated position;

[0033] Finally, after the graphite column contacts the ground, the crane is controlled to make the device continue to fall. At this time, the upper end of the graphite column will push up the top plate 1, so that the angle between the first clamping bar 2 and the first connecting rod 5 at the rotation connection is reduced, and at the same time, the angle between the second clamping bar 3 and the second connecting rod 4 is reduced, and the angle between the second connecting rod 4 and the first connecting rod 5 is increased, so that the lower ends of the first clamping bar 2 and the second clamping bar 3 are opened to each other, and the device is quickly lifted to complete the unloading of the graphite column.
