As shown in fig. 17, in the present embodiment, the locking buckle includes a protrusion 61 and a groove 62 capable of cooperating with each other, the protrusion 61 is disposed on a side of the connecting plate 144 away from the connecting plate rotating shaft 53, the groove 62 is disposed on the right lower pedal 143, and when the connecting plate 144 is in the second working position, the connecting plate 144 rides on the right lower pedal 143 and the protrusion 61 is located in the groove 62.

Referring to fig. 5 to 20, the working principle of the embodiment is as follows:

the first case: when the seat frame 13 is switched between the forward working position and the backward working position, the seat frame 13 is not contacted with the push handle rod 4.

When the seat frame 13 needs to be switched from the forward working position to the backward working position, the pedal 14 is turned upwards and forwards, then the seat frame 13 is rotated until the seat frame 13 faces backwards, then the pedal 14 is turned downwards and backwards, in the turning process of the pedal 14, the connecting plate 144 is turned around the connecting plate rotating shaft 52 under the action of the push handle rod 4 to open the strip-shaped dividing hole 15, the push handle rod 4 enters the strip-shaped dividing hole 15, after the push handle rod 4 is separated from the connecting plate 144, the connecting plate 144 is reset to close the strip-shaped dividing hole 15, and the push handle rod 4 is located in the strip-shaped dividing hole 15.

When the seat frame 13 needs to be converted from the backward working position to the forward working position, the pedal plate 14 is turned upwards and forwards, in the turning process of the pedal plate 14, the connecting plate 144 is turned around the connecting plate rotating shaft 52 under the action of the push handle rod 4 to open the strip-shaped dividing holes 15, the push handle rod 4 leaves the strip-shaped dividing holes 15, after the push handle rod 4 is separated from the connecting plate 144, the connecting plate 144 is reset to close the strip-shaped dividing holes 15, the push handle rod 4 is located outside the strip-shaped dividing holes 15, then the seat frame 13 is rotated forwards to the seat frame 13, and then the pedal plate is turned downwards and forwards.

The second situation is that: when the seat frame 13 is switched between the forward working position and the backward working position, the seat frame 13 interferes with the push handle rod 4.

When the seat frame 13 needs to be switched from the forward working position to the backward working position, the push handle rod 4 is turned downwards and backwards, the pedal plate 14 is turned upwards and forwards, then the seat frame 13 is rotated to the backward position of the seat frame 13, the push handle rod 4 is turned upwards and forwards, then the pedal plate 14 is turned downwards and backwards, in the turning process of the pedal plate 14, the connecting plate 144 is turned around the connecting plate rotating shaft 53 under the action of the push handle rod 4 to open the strip-shaped dividing holes 15, the push handle rod 4 enters the strip-shaped dividing holes 15, after the push handle rod 4 is separated from the connecting plate 144, the connecting plate 144 is reset to close the strip-shaped dividing holes 15, and the push handle rod 4 is located in the strip-shaped dividing holes 15.

When the seat frame 13 needs to be switched from the backward working position to the forward working position, the pedal plate 14 is turned upwards and forwards, in the turning process of the pedal plate 14, the connecting plate 144 enables the strip-shaped dividing holes 15 to be opened around the connecting plate rotating shaft 53 under the action of the push handle rod 4, the push handle rod 4 leaves the strip-shaped dividing holes 15, after the push handle rod 4 is separated from the connecting plate 144, the connecting plate 144 resets to enable the strip-shaped dividing holes 15 to be closed, the push handle rod 4 is located outside the strip-shaped dividing holes 15, then the push handle rod 4 is turned downwards and backwards, the seat frame 13 is rotated to the seat frame 13 forwards, and finally the pedal plate 14 is turned downwards and forwards.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
