[0002] A forklift is a lifting vehicle equipped with lifting forks at the front and counterweights at the rear. Forklifts are suitable for loading, unloading, stacking, and handling packaged goods in ports, stations, and enterprises. Forklifts under 3 tons can also operate in ship holds, train carriages, and containers. By replacing the forks with various attachments, forklifts can handle a variety of goods. For example, by replacing the forks with buckets, they can handle bulk materials. Self-propelled forklifts appeared in 1917 and were developed during World War II. my country began manufacturing forklifts in the early 1950s.
[0003] Counterbalance forklifts can only lift and unload goods using the bottom blades. When the bottom of the goods is unbalanced and the stress points are only on both sides, they cannot be lifted and unloaded, resulting in a decrease in unloading speed. Therefore, there is an urgent need for a dual-purpose unloading device for counterbalance forklifts to overcome the above defects. Summary of the Invention
[0004] The purpose of this invention is to provide a dual-purpose unloading device for counterbalanced forklifts, which has the advantages of convenient unloading and high applicability, in order to solve the problems mentioned in the background art.

The movable adjustment assembly is located on the left side of the forklift body, and the movable fixing assemblies are located on both sides of the movable adjustment assembly. The lifting movable assembly is located at the bottom of the movable adjustment assembly. The movable adjustment assembly includes a positioning block, a moving rod, a first sliding groove, a first sliding block, a dual-axis motor, a first threaded rod, and a positioning groove. The lifting movable assembly includes a fourth sliding groove, a third threaded rod, a fourth sliding block, a fixing frame, a lifting blade holder, a third sliding block, a third sliding groove, and a third motor. The movable fixing assembly includes a connecting rod, a second threaded rod, a second motor, a second sliding groove, a positioning clamp, and a second sliding block.
[0006] Furthermore, the positioning block is fixedly installed on the left side of the forklift body, the positioning groove is opened inside the positioning block, the dual-axis motor is fixedly installed at the center of the positioning groove cavity, and the moving rods are all arranged on both sides of the positioning groove cavity.
[0007] Furthermore, the first threaded rod rotates inside the moving rod via a thread, the output shaft of the dual-axis motor is fixedly connected to the side of the first threaded rod that is relatively close to it, the first slide groove is opened at the bottom of the moving rod, and the first slider slides in the inner cavity of the first slide groove.
[0008] Furthermore, the bottom of the first slider is fixedly connected to the inner cavity of the positioning groove, the connecting rod is fixedly installed on the left side of the moving rod, the second slide groove is opened inside the connecting rod, and the second slider slides inside the second slide groove.
[0009] Furthermore, the positioning clamp is fixedly installed on the side of the second slider that is relatively close to it, the second motor is fixedly installed on the left side of the connecting rod, the second threaded rod rotates inside the second slider through the thread, and the output shaft of the second motor passes through the inner cavity of the second slide groove and is fixedly connected to the left side of the second threaded rod.
[0010] Furthermore, the fourth slide groove is formed on both sides of the bottom of the positioning block, the third motor is fixedly installed on the right side of the positioning block, the third slide groove is formed at the center of the bottom of the positioning block, and the third slider slides in the inner cavity of the third slide groove.

[0013] In summary, due to the adoption of the above-mentioned technologies, the beneficial effects of this utility model are:
[0014] This invention facilitates the transfer and lifting of goods by designing a forklift body. A movable adjustment component adjusts the position of the movable fixing component, indirectly securing the goods on both sides. A lifting movable component lifts the goods. In use, when goods need to be clamped, the dual-axis motor and the second motor are activated. The dual-axis motor drives the first threaded rod to rotate, while the second motor drives the second threaded rod. Based on the volume of the goods, the second threaded rod moves the second slider and positioning clamp to a designated position. The movable rod then moves the connecting rod inward, securing the goods under the action of the positioning clamp. For regular lifting, the third motor is activated, driving the third threaded rod to rotate. This causes the third slider to move the lifting blade holder, fixing frame, and fourth slider to the left, lifting the goods under the action of the lifting blade holder. This design offers advantages such as convenient unloading and high applicability. It solves the problem that counterbalanced forklifts can only lift and unload goods using the bottom blade, and when the bottom of the goods is unbalanced and the force points are only on both sides, it is impossible to lift and unload them, resulting in reduced unloading speed.
