[0030] Embodiment two:

[0031] On the basis of embodiment one, in order to effectively avoid the risk of material falling due to instability during carrying, and thus ensure the safety and efficiency of carrying operation, the forklift is also provided with a material fixing unit. The material fixing unit includes a motor two 501, a fixed seat 502, a rotating shaft 503, a connecting seat 504, an electric push rod 505 and a telescopic blocking plate 506. The motor two 501 provides power to drive the action execution of the material fixing unit. The fixed seat 502 has two fixed connections on the upper surface of the tool holder 3.

The outer gantry 201 is fixedly connected to the front sides of the vehicle body 1. The inner gantry 202 has two ends hingedly connected to the outer gantry 201. The other end of the inner gantry 202 is connected to the accessory rack 3 through a connecting structure. The lifting cylinder 203 has two groups respectively arranged between the outer gantry 201 and the inner gantry 202. The bottom end of the inclination cylinder 204 is connected to the middle part of the outer gantry 201. The other end of the inclination cylinder 204 is connected to the movable connecting frame 205. The fixed support 206 is fixedly connected between the two inner gantries 202. The movable connecting frame 205 is hingedly connected to the fixed support 206. One end of the connecting support 207 is hingedly connected to the bottom of the movable connecting frame 205. The other end of the connecting support 207 is connected to the middle part of the accessory rack 3 through a connecting structure. The connecting structure includes a connecting plate and a pin shaft. The connecting plate is fixedly connected to the accessory rack 3.

The inclination cylinder 204 is used to adjust the inclination angle of the accessory rack 3 to adapt to different working environments.

[0034] According to the size of the material to be carried, the rotation direction and speed of the motor one 306 are controlled to adjust the distance between the two forks 305. The threaded rod 304 is driven to rotate by the motor one 306. Since the threads on both ends of the threaded rod 304 are opposite, the two forks 305 can move simultaneously but in opposite directions, adjusting their distance to adapt to different sizes of materials. The guide rod 303 ensures that the forks 305 maintain straight-line motion during sliding, improving the accuracy of adjustment. Insert the forks 305 under the material, lift the accessory rack 3, and carry the material to the designated location. If metal goods need to be carried, the electromagnet 4 can be activated for additional fixation.

[0035] During the carrying process, according to the shape and stability requirements of the material, the extension and retraction of the electric push rod 505 are controlled to adjust the position of the telescopic blocking plate 506, so that it closely fits the material to prevent it from falling. The motor two 501 provides power to drive the shaft to rotate, and the electric push rod 505 adjusts the position of the telescopic blocking plate 506 through extension and retraction, achieving stable fixation of the material.
