When the patient drives the wheelchair to travel, the objects he needs to carry with him can be placed on the placement plate, which makes it convenient for the patient to carry items and avoids the situation where the patient cannot place the items at any time when driving the wheelchair to travel, thereby improving the convenience of using the wheelchair.

[0022] 3. In the present invention, by setting a limit block, when an object is placed on the placement plate, the insertion rod is pulled to make the insertion rod slide out of the round rod. At this time, the second spring will pull the rectangular plate due to the recovery of elastic force. At this time, the rectangular plate will drive the round rod to slide, so that the round rod pushes the limit block, and then the limit block clamps the object on the placement plate, thereby achieving the purpose of positioning the object, avoiding that the object on the placement plate will fall off the placement plate due to inertia when the wheelchair stops suddenly. When the object needs to be removed from the placement plate, the round rod is pulled, so that the round rod drives the limit block to slide, so that the limit block no longer contacts the object, and then the insertion rod is pushed to make the insertion rod slide into the round rod, and then the object is removed from the placement plate.

At this time, the second spring 21 pulls the rectangular plate 20 due to the recovery of the elastic force. At this time, the rectangular plate 20 drives the round rod 19 to slide, so that the round rod 19 pushes the limit block 23, and then the limit block 23 clamps the object on the placement plate 7, thereby achieving the effect of positioning the object, preventing the object on the placement plate 7 from falling off the placement plate 7 due to inertia when the wheelchair stops suddenly. When the object needs to be removed from the placement plate 7, the round rod 19 is pulled, so that the round rod 19 drives the limit block 23 to slide, so that the limit block 23 no longer contacts the object, and then the insertion rod 18 is pushed, so that the insertion rod 18 slides into the round rod 19.After that, the item is removed from the placement plate 7 and the glass is placed in the placement tube 25. The placement tube 25 can now carry the glass, and the sponge ring 24 can protect the glass, preventing the patient from being unable to place the glass on the placement plate 7 for carrying due to the glass's fragility. The slide plate 27 is slid upwards, dragging the glass upwards, and then removing the glass. The slide plate 27 is then released, allowing the third spring 28 to pull the slide plate 27 due to the recovery of its elastic force, thereby returning the slide plate 27 to its original position.
