The first support rod 22 includes a crossbar 221 and a vertical rod 222. One end of the crossbar 221 is connected to the other side of the connecting frame 21, and the other end of the crossbar 221 is connected to the vertical rod 222, and the vertical rod 222 is extended upward; there are two second support rods 23, and the second support rods 23 are located at the first support rods 23. Above the connecting frame 22, internal threads are arranged on the two second support rods 23, the screw rod 24 is rotatably arranged on the connecting frame 21, and the screw rod 24 is arranged on an external thread corresponding to the internal thread, and the two second support rods 23 are symmetrically arranged on the screw rod 24 and pass through the side where the connecting frame 21 is connected to the first support rod 22; wherein, one end of the screw rod 24 passes through the connecting frame 21 and is flush with the outer side wall of the connecting frame 21, and a square groove 241 is arranged on the end of the screw rod 24 passing through the connecting frame 21, and the central axis of the square groove 241 coincides with the central axis of the screw rod 24. The handle 25 includes a block 251, a connecting rod 252 and a rocker 253. One end of the block 251 can be detachably mounted in the square groove 241. The other end of the block 251 is connected to one end of the connecting rod 252, and the length direction of the block 251 is set at 90 degrees to the length direction of the connecting rod 252. The other end of the connecting rod 252 is connected to the rocker 253, and the length direction of the rocker 253 is parallel to the length direction of the block 251.

[0030] like Figure 1-Figure 2 As shown, the feed mechanism 3 includes a feed bracket 31 and a feed assembly 32. The feed mechanism 3 is vertically slidably arranged on the lifting mechanism 1 through a first connecting mechanism 33. The first connecting mechanism 33 includes a first lead screw 331, a first guide rod 332, a first nut 333 and a first sleeve 334. The first lead screw 331 and the first guide rod 332 are both vertically arranged on the lifting mechanism 1. The first nut 333 is screwed with the first lead screw 331. The first nut 333 is connected to the feed bracket 31. The first sleeve 334 is sleeved on the outside of the first guide rod 332 and vertically slides along the first guide rod 332. The first sleeve 334 is connected to the feed bracket 31. The feed assembly 32 includes a plurality of conveying rollers 321. The plurality of conveying rollers 321 are evenly arranged on the feed bracket 31. The cross-sectional diameter of the conveying rollers 321 is smaller than the distance between two adjacent first support rods 22, and the distance between two adjacent conveying rollers 321 is sufficient for the first support rod 22 and the second support rod 23 to pass through.

[0031] The structure of the discharge mechanism 4 and the feeding mechanism 3 is arranged in a mirror image, and the feeding mechanism 3 and the discharge mechanism (4) are located on both sides of the lifting mechanism 1. In the utility model, the height of the discharge mechanism 4 is arranged to be higher than the height of the feeding mechanism 3, that is, the product is transported to a high position. In actual use, the height of the discharge mechanism 4 can also be lower than the height of the feeding mechanism 3 to realize the transportation of products to a low position.

[0032] Before using the utility model, the distance between the two second support rods 23 is adjusted according to the width of the product to be conveyed. The adjustment process is as follows: the block 251 of the handle 25 is clamped in the square groove 241, and the rocker 253 is rotated. The rocker 253 drives the connecting rod 252 and the block 251 to rotate, and the block 251 drives the screw 24 to rotate, so that the two second support rods 23 move in opposite directions or opposite directions along the screw 24, thereby reducing or increasing the distance between the two second support rods 23. After the adjustment is completed, the block 251 is pulled out of the square groove 241, that is, the handle 25 is removed, and the lifting action of the frame mechanism 2 is not affected. When using the device to lift products, the products to be lifted are placed on the conveying roller 321 of the feeding mechanism 3, so that when the frame mechanism 2 passes through the feeding mechanism 3, the supporting products are transferred from the conveying roller 321 to the crossbar 221 of the first support rod 22, and the crossbar 221 supports the products. The two second support rods 23 and the vertical rod 222 are used to limit the products to prevent the products from falling. When the frame mechanism 2 passes through the discharging mechanism 4, the supported product is transferred from the cross bar 221 to the discharging mechanism 4, so that the product can be discharged along the discharging mechanism 4. The above actions can be repeated to realize the process of lifting the product back and forth.

[0033] The above description is only a preferred embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
