When the oven door 7 is opened, if more moisture exists in the oven, hot waves are easily generated, even the hands of a user are burnt, at this time, the user can extend the length of the operating handle 18, and the used operating handle 18 extends to the outer side of another closed oven door 7 or extends to the box body 1 which is already opened (no hot waves or radiation), so that not only is the labor saved (leverage effect) achieved, but also the hands of the user who opens the oven door 7 are not right opposite to the opened oven door 7 and have a larger distance from the edge of the opened oven door 7, so that the hands can be well prevented from being burnt by steam, and the use safety is higher, wherein the specific use method is as follows:

taking fig. 7 as an example, the operator holds the operating handle 18 and rotates downward, and rotates the connecting portion 19 while rotating the left side of the driving portion 20 upward, in the process, the first elastic member 21 is further elastically compressed, and the first interlocking portion 23 rotates upward while the second elastic member 25 is further elastically compressed; the first linkage part 23 drives the linkage part 22 to rotate anticlockwise, so that the second linkage part 24 rotates downwards until the first locking body 26 is separated from the second locking body 29, namely the first locking body 26 is positioned below the second locking body 29, in the state, the upper side of the first linkage part 23 or the linkage part 22 is abutted against the lower side of the indication column 36, the lower side of the second linkage part 24 is abutted against the lower side of the inner wall of the positioning cylinder 16, and a plurality of structures are contacted simultaneously; then, the operating handle 18 can be pulled rightwards for a certain distance, such as 0.5-1cm, while being kept in a state of rotating downwards, then the operating handle 18 is loosened, the operating handle 18 and the first linkage part 23 move downwards under the elastic action of the first elastic piece 21 and the second elastic piece 25, at this time, the first locking body 26 moves upwards, but at this time, the first locking body 26 and the second locking body 29 are not locked with each other, so that the operating handle 18 can be pulled rightwards continuously, and meanwhile, the whole movable cylinder 17 is driven to move rightwards through the connecting part 19;

in the process of the movement, the limiting rod 34 passes through the abdicating hole 33, so that the limiting rod 34 does not influence the normal movement of the movable cylinder 17 and the linkage piece 22; the operating handle 18 is continuously pulled until the protective column 35 collides with the limiting column, at this time, the operating handle 18 is elongated to the limit and cannot be pulled forwards continuously, at the same time, the operating handle 18 has a longer distance from the edge of the oven door 7 to be opened, which can reach 20-25cm according to practical situations, and then the operating handle 18 is pulled outwards, so that the oven door 7 can be opened through the operating handle 18, the movable cylinder 17 and the positioning cylinder 16, and the distance between the operating handle 18 and the hinge joint of the oven door 7 to be opened and the box body 1 is larger, so that the oven door 7 is opened more easily. And in the above operation, the oven door 7 is subjected to the attraction of the positioning magnet 8, i.e. is in a sealed state with the oven body 1, until the oven door 7 is opened by the operation handle 18.

Wherein, because the gap between the hand of the operator and the edge of the opened oven door 7 is 20-25cm, at first much steam can not act on the hand, and even if acting on the hand, because the distance is far and the temperature of the external air is low relative to the oven, the steam can be cooled down rapidly, thereby preventing the user from being burnt well, and ensuring the use safety sufficiently.

After use, the movable cylinder 17 is inserted into the positioning cylinder 16 by operating the handle 18. Wherein it continues to be clear during this insertion (the width of the second linkage part 24 and the first locking body 26 being smaller, e.g. through the wire or through the stop ring 27) until the first locking body 26 interferes with the second locking body 29. The first locking body 26 abuts against the arc-shaped lower side of the second locking body 29 through the arc-shaped upper side of the first locking body, so that when the operating handle 18 continues to drive the movable cylinder 17 into the positioning cylinder 16, the first locking body 26 receives a downward acting force, the second locking body 29 receives a downward acting force, and the third elastic element 30 and the second elastic element 25 are both compressed, wherein in the embodiment, the deformation of the third elastic element 30 is mainly (with a smaller diameter), and the second elastic element 25 generates a small elastic deformation, so that the second elastic element 25 can keep the position thereof stable, and thus the driving part 20 is continuously pressed through the first linkage part 23, so that the driving handle can be kept from rotating or slightly rotating, and the operation stability can be higher.

After the third elastic member 30 is elastically deformed, the second locking body 29 is lifted, the first locking body 26 is continuously driven to move by the operating handle 18 until the indication column 36 abuts against the limiting rod 34, at this time, the first locking body 26 and the second locking body 29 are just in a dislocated state, the end part of the movable cylinder 17 abuts against the stop ring 27, then, under the action of gravity of the third elastic member 30 and the second locking body 29, the second locking body 29 moves downwards until the first locking body 26 is locked, the homing of the operating handle 18 and the movable cylinder 17 is completed, and the operation is simple and convenient and only the operating handle 18 needs to be pushed.

Furthermore, during the downward movement of the second locking body 29, the supporting block 31 is located at the lower side or side of the second locking body 29, so that the supporting block 31 does not affect the normal movement of the second locking body 29, but when the second locking body 29 locks the first locking body 26, the supporting block 31 restricts the second locking body 29 from further downward movement by the fitting block 32; thus, when the first locking body 26 and the second locking body 29 are unlocked subsequently, that is, when the first locking body 26 rotates downward, the second locking body 29 can not move downward any more under the supporting action of the supporting block 31, so that the first locking body 26 can normally pass through the lower side of the second locking body 29.

Wherein, in the using process, the protection piece 37 is positioned between the four fingers and the oven door 7, which can prevent the fingers from rubbing or being burnt, and further improves the use safety. And the guard 37 is spaced from one end of the operating handle 18, so that the guard 37 does not interfere with the rotation of the operating handle 18. If the position of the operating handle 18 does not need to be changed, i.e., if the movable barrel 17 does not need to be extended, only the operating handle 18 needs to be pulled directly outward; the two ends of the operating handle 18 are limited by the movable cylinder 17 and the protective body 38, so that the acting force of the operating handle 18 can be better dispersed, and the deformation of the joint of the operating handle 18 and the movable cylinder 17 is better prevented. Meanwhile, since the opening between the protection body 38 and the oven door 7 is downward, the protection body 38 does not affect the normal downward rotation of the operating handle 18. And the heights of the positioning cylinders 16 on the two oven doors 7 are different when in use, so that the mutual influence between the operating handles 18 on the two sides can be prevented.

It should be noted that, in the present specification, the embodiments are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments may be referred to each other.

The above description is only for the purpose of describing the preferred embodiments of the present invention, and is not intended to limit the scope of the present invention, and any variations and modifications made by those skilled in the art based on the above disclosure are within the scope of the appended claims.
