For example, as shown in fig. 1 and fig. 2, two positioning holes 211 are formed on the guide wheel seat 210, and correspondingly, two positioning pins 121 are correspondingly installed on the door frame 120. When the oven door 200 is closed, the oven door 200 is attached to the door frame 120 to seal the baking cavity 110, and meanwhile, the positioning pin 121 on the door frame 120 is inserted into the positioning hole 211 on the guide wheel seat 210 to limit the oven door 200 in the left-right direction, so that the oven door 200 is prevented from moving left and right along the moving track.

Further, a clamp 130 is arranged in the baking cavity 110, a movable swing rod 131 is arranged on the clamp 130, a clamping groove 122 corresponding to the swing rod 131 is arranged on the door frame 120, and when the clamp 130 is in the baking cavity 110, the swing rod 131 can be connected with the clamping groove 122, so that the clamp 130 is fixed in the baking cavity 110. For example, as shown in fig. 2, a plurality of swing rods 131 are spaced apart from each other on a side surface of the door frame 120, and a plurality of engaging grooves 122 corresponding to the swing rods 131 are spaced apart from each other on an edge of the jig 130. When the clamp 130 is located in the baking cavity 110, the swing link 131 can be clamped in the slot 122, so that the clamp 130 is fixed in the baking cavity 110; when the clamp 130 needs to leave the baking cavity 110, the swing link 131 rotates upwards, the connection between the swing link 131 and the card slot 122 is broken, and at this time, the clamp 130 can be pulled out of the baking cavity 110 under the action of external force. The swing rod 131 and the clamping groove 122 are arranged, so that the clamp 130 and the furnace body 100 can be detachably connected.

Specifically, as shown in fig. 8, the clamp is provided with air bag supporting structures 132, a clamping groove is formed between two adjacent air bag supporting structures 132, the lithium battery 400 is clamped in the clamping groove, and the middle part of the air bag supporting structure 132 can protrude towards the clamping groove to abut against the air bag of the lithium battery 400, so that the air bag in the lithium battery 400 is prevented from expanding.

Further, the clamp 130 is connected to the furnace body 100 through a hollow folding rod 140, and a wire for connecting the clamp 130 and the furnace body 100 is distributed in the hollow portion of the folding rod 140. For example, as shown in fig. 7, the clamp 130 may be disposed in the oven cavity 110, the clamp 130 may be connected to the oven body 100 by a folding bar 140, the folding bar 140 may have a hollow interior, a wire may be disposed in the folding bar 140, and the clamp 130 and the oven body 100 may be electrically connected by a wire. Compared with the conventional method of electrically connecting the clamp 130 and the oven body 100 by using a probe, the vacuum discharge in the baking chamber 110 when the clamp 130 and the oven body 100 are electrically connected can be avoided by arranging a wire for communicating the clamp 130 and the oven body 100 in the hollow folding rod 140.
