However, this operation method not only requires the materials to be bundled in advance during actual use, but also the materials are prone to shaking in the air during the rising process, and the stability is poor. For this reason, we propose a crane that can perform multiple fixations on materials to solve the above problems. Utility Model Content

[0023] By installing a cross bar 6 at the bottom end of the driving disk 3, when in use, the first driving motor 4 can be driven to rotate the winch 2, so that the winch 2 releases the cable, and the driving disk 3 drives the cross bar 6 to move downward to above the material, and then the second driving motor 7 is driven to make the bidirectional threaded rod 8 rotate in the cross bar 6, so that the two groups of threaded sleeves 9 outside the bidirectional threaded rod 8 can drive the two groups of vertical rods 12 to move in opposite directions under the guidance of the threads and the two groups of guide blocks 11, so that the two groups of vertical rods 12 are moved to both sides of the material to fix and clamp the two sides of the material, and then a movable bottom frame plate 14 is installed at the bottom ends of the two groups of vertical rods 12, so that the two groups of bottom frame plates 14 can support and fix the bottom end of the material, thereby forming multiple fixations of the material, so that the material can be effectively fixed during the rising process, thereby improving the stability of the device when in use.

[0024] In other embodiments, the positioning assembly includes a sleeve 15, a movable block 16, a positioning rod 17, a positioning hole 18, a handle 19 and a reset spring 20. The sleeve 15 is fixed to the outside of the lower end of the two sets of vertical rods 12, and the movable block 16 is arranged inside the sleeve 15. The bottom ends of the two sets of movable blocks 16 are fixed with positioning rods 17. A plurality of sets of positioning holes 18 are provided at equal intervals on the bottom frame plate 14. The bottom ends of the two sets of positioning rods 17 can be inserted into the positioning holes 18. The tops of the two sets of movable blocks 16 are fixed with handles 19, and the reset springs 20 are wound around the outsides of the two sets of handles 19.

[0025] By installing a liftable positioning rod 17 on the outside of the vertical rod 12, when it is necessary to lift materials of different sizes, the handle 19 can be pulled upward to allow the movable block 16 to drive the positioning rod 17 to move upward along the sleeve 15, and allow the movable block 16 to squeeze the return spring 20 on the outside of the handle 19. When the positioning rod 17 completely leaves the positioning hole 18 on the base plate 14, the base plate 14 can be pushed to allow the base plate 14 to move horizontally along the through groove 13 at the bottom end of the vertical rod 12. The extension length of the base plate 14 is adjusted according to the volume of the material, and the upward pulling force on the handle 19 is released, so that the return spring 20 releases the elastic force to push the movable block 16 downward, and the positioning rod 17 is inserted into the positioning hole 18 at the corresponding position under the drive of the movable block 16, thereby quickly completing the movable limit of the base plate 14, thereby improving the convenience of using the device.

[0026] In other embodiments, grooves 21 are formed at opposite ends of the two sets of bottom frame plates 14;

[0027] This design makes it easy to hang some soft packages such as ropes in the groove 21, so that the drive disc 3 can quickly lift them.

[0029] Through this design, the external controller can control the start and stop of the second drive motor 7 and the first drive motor 4 in real time, ensuring that the second drive motor 7 and the first drive motor 4 can be used normally.

[0030] In other embodiments, the outer wall of the movable block 16 is fully fitted with the inner wall of the sleeve 15, and the movable block 16 and the sleeve 15 are slidably connected;

[0031] With this design, when the movable block 16 slides up and down along the inside of the sleeve 15 , it is possible to effectively prevent the movable block 16 from shaking during the movement.

[0032] In other embodiments, the top of the pull handle 19 is designed to be spherical;

[0033] This design increases the contact area between the top of the handle 19 and the user's hand, making it easier to effectively pull the handle 19.

[0034] In other embodiments, both ends of the return spring 20 are connected to the outer wall of the movable block 16 and the inner wall of the sleeve 15 respectively;

[0035] With this design, the return spring 20 can exert a downward elastic force on the movable block 16 , so that the movable block 16 can drive the positioning rod 17 to quickly insert into the positioning hole 18 on the bottom frame plate 14 .

[0036] The electrical components mentioned in this article are all connected to an external main controller and industrial power supply, and the main controller can be a conventional known device for control such as a computer.
