Also, the terms "upper", "lower", "left", "right", "middle" and "a" are used herein for descriptive purposes only and are not intended to limit the scope of the invention for which the invention may be practiced, but rather the relative relationships thereof may be altered or modified without materially altering the technology.

In the embodiment of the present invention, as shown in fig. 5, the up-down direction of the paper surface is defined as the front-back direction; as shown in fig. 1, the up-down direction of the paper surface is defined as the up-down direction.

As shown in fig. 1 to 18, the invention provides a cooker with locking function, comprising a cooker body 1 and a cooker cover 2 covered on the cooker body 1, wherein handles 3 are arranged on both side walls of the cooker body 1, each handle 3 comprises a connecting sheet 31 fixedly connected with the side wall of the cooker body 1 and a holding block 32 arranged on the connecting sheet 31, the holding block 32 is provided with a locking surface 321, the holding block 32 can move along the direction approaching to and separating from the cooker body 1, and when the holding block 32 moves to a set position along the direction approaching to the cooker body 1, the locking surface 321 is contacted with the cooker cover 2; when the holding block 32 moves to the set position in the direction away from the pot body 1, the locking surface 321 is disengaged from the contact engagement with the pot cover 2. When the cooker with the locking function is used, when the whole cooker is required to be inclined, and in order to prevent the cooker cover 2 from sliding off from the cooker body 1, the holding blocks 32 of the two handles 3 are respectively held by two hands, the holding blocks 32 are manually pushed to move to a set position relative to the connecting sheet 31 along the direction close to the cooker body 1, at the moment, the locking surfaces 321 on the two holding blocks 32 are both contacted with the cooker cover 2 and jointly apply clamping acting force to the cooker cover 2, so that the cooker cover 2 is locked on the cooker body 1 by utilizing the clamping acting force, namely the cooker cover 2 is fixed on the cooker body 1, and further, the cooker cover 2 is prevented from sliding off from the cooker body 1 when the whole cooker is inclined; when the pot cover 2 needs to be opened, the two holding blocks 32 move to the set position relative to the connecting sheet 31 along the direction away from the pot body 1, and at the moment, the locking surface 321 is separated from contact fit with the pot cover 2, and the holding blocks 32 lose locking effect on the pot cover 2, so that the pot cover 2 is conveniently opened.

As shown in fig. 1 and 2, the locking surface 321 in this embodiment is an arc surface. Thus, when the locking surface 321 contacts the pot cover 2, the locking surface 321 will apply an oblique force to the pot cover 2, the oblique force having a force in the horizontal direction and toward the pot cover 2 and a force in the vertical direction and toward the pot body 1; and under the action of two oblique forces applied to the pot cover 2 by the two holding blocks 32, the pot cover 2 can be effectively locked on the pot body 1. Meanwhile, the locking surface 321 with the arc surface effectively ensures that the locking surface 321 can smoothly contact with the pot cover 2, and ensures that the oblique force has larger acting force along the vertical direction and towards the pot body 1, thereby ensuring that the locking surface 321 can firmly lock the pot cover 2 on the pot body 1.
