[0025] It should be noted that the worker of forklift 1 referred to the body part of the forklift model CPD-20. The insertion rod 402 can be flipped through the articulated seat 401. When the insertion rod 402 is flipped to the front end of the sliding frame 301 as the center of the circle, the operator can use a thick cable tie to connect the insertion rod 402 to the front end of the sliding frame 301.

[0026] Specifically, the hydraulic unit 2 includes a hydraulic rod 201 and a lifting lug 202. The lifting lug 202 is provided at the top of the forklift 1 and is located near one end of the sliding frame 301. The bottom end of the hydraulic rod 201 is hinged to the top end of the lifting lug 202. The output end of the hydraulic rod 201 is hinged to the end of the sliding frame 301 near the forklift 1. The front end of the sliding frame 301 is provided with a guide rail frame 203.

[0027] It should be noted that the hydraulic rod 201 and the lifting lug 202 are based on the pushing part of the forklift model CPD-20. The bottom end of the sliding frame 301 is hinged to the front end of the forklift 1. When the hydraulic rod 201 pushes the sliding frame 301, the sliding frame 301 will rotate in a circle with the hinge point as the hinge point, and the sliding frame 301 will drive the guide rail frame 203 to rotate to adjust the angle of the insertion rack 4.

[0028] Specifically, the sliding part 3 includes a sliding baffle 302 and a sliding rod 303. The end of the sliding baffle 302 close to the forklift 1 is slidably connected to the outer wall of the guide rail frame 203, and the sliding rod 303 is fixedly connected to the front end of the sliding baffle 302. The ends of multiple insertion racks 4 close to the sliding baffle 302 are slidably connected to the outer wall of the sliding rod 303. The inner walls of multiple hinged seats 401 are provided with movable grooves 403, and the inner walls of the movable grooves 403 are hinged to the bottom ends of the insertion rods 402.

[0029] It should be noted that the working principle of the sliding baffle 302 and the sliding rod 303 is the same as the movable part of the forklift model CPD-20. Rollers are provided at the connection between the sliding baffle 302 and the sliding frame 301. The sliding baffle 302 is lifted and slid on the outer wall of the guide rail frame 203 through the rollers. The insertion rod 402 can also slide on the outer wall of the sliding rod 303 through the insertion frame 4. The insertion rod 402 adjusts the spacing through the sliding rod 303, and the material is forked up by the insertion rod 402 under the push of the forklift 1.

[0030] Specifically, a plurality of fixing grooves 501 are provided at the top of the multiple hinged seats 401 and at one end close to the insertion rod 402. The top ends of the multiple fixing grooves 501 are socketed with the bottom ends of the multiple fixing plates 502. The top ends of the multiple fixing plates 502 are threadedly connected with a plurality of fixing bolts 503. The outer walls of the multiple fixing bolts 503 are threadedly connected with the top ends of the multiple fixing grooves 501.

[0031] It should be noted that the hinged seat 401 is fixed to the bottom end of the rack 4 by welding, and the hinged seat 401 can slide together with the rack 4. The inner wall of the hinged seat 401 is provided with a hinged rod, and the rod 402 can be rotated with the hinged rod as the center of the circle. When the rack 4 is rotated to one end of the fixed groove 501, the fixed block 5 will be sleeved on the inner wall of the fixed groove 501, and the operator will then sleeve the fixed plate 502 on the top of the fixed block 5, and thread the fixing bolt 503 through the fixing plate 502 and the fixed block 5, and the fixing plate 502 and the fixing bolt 503 cooperate with each other to clamp the fixed block 5 on the inner wall of the fixed groove 501.

[0032] Working principle of this utility model:

[0033] The specific operation is that when the operator drives the forklift 1 to a place with a narrow space, the operator needs to flip the rod 402 90 degrees through the hinge seat 401, flip the rod 402 and fix it in front of the sliding baffle 302. When it is necessary to lift materials, the operator needs to flip the rod 402 again through the hinge seat 401 to the inner wall of the movable groove 403. At the same time, the fixing block 5 of the rod 402 will be sleeved on the inner wall of the fixing groove 501, and then the fixing plate 502 is pressed onto the top of the fixing block 5. Finally, the fixing block 5 and the fixing groove 501 are threadedly inserted into the top of the hinge seat 401 through the fixing bolt 503. The operator can start the forklift 1 at this time. It is necessary to open the hydraulic rod 201, and the output end of the hydraulic rod 201 will push the sliding frame 301. The sliding frame 301 will be slightly flipped under the push of the hydraulic rod 201, and the flipping is used to adjust the insertion rod 402 to be kept at the same level as the material. Then, the spacing between multiple insertion rods 402 is adjusted by sliding the insertion frame 4 horizontally on the sliding rod 303. The forklift 1 is operated to insert the adjusted insertion rod 402 through the bottom end of the material. Finally, the operator can lift the sliding baffle 302 at the front end of the sliding frame 301. The sliding baffle 302 will drag the insertion rod 402 and the material to rise and fall. Finally, the material is transported to the handling position by the forklift 1 and then unloaded manually.
