When the user uses the dough kneading cylinder 50, if water needs to be added into the dough kneading cylinder, the water can be added through the grid on the protective cover 17 until the flour and the water are stirred into dough, the mixing can be stopped through the control panel 26, and in the process, the arc-shaped scraper knife 18 on the dough separating rod 12 shovels the flour adhered to the bottom of the dough kneading cylinder 50 at any time, so that the flour participates in the mixing process. It should be noted that, during the mixing, the rotation speed of the driving motor 13 can be controlled by the control panel 26 and the control circuit board, so as to change the mixing speed of the dough kneading rod 11 and the dough kneading cylinder 50.

After the flour is mixed with the water into the dough, the user desires to separate the upper body 10 from the lower body 20, take out the dough kneading cylinder 50, and then take out the dough and wash the dough kneading cylinder 50. The user pulls the connecting rod 27 shared by the locking pins 22, the end a of the locking pin 22 is separated from the locking hole 110 of the locking plate 19, the user grasps the solid part of the upper body 10 and exerts force upwards, the upper body 10 is opened upwards, meanwhile, the gas spring is stressed and extended until the upper body 10 and the lower body 20 are opened at a certain angle, the gas spring is not extended any more, the gas spring plays a role in supporting and connecting, because the inclined groove 36 is not provided with a device for blocking the pin 34 from being separated from the inclined groove 36, therefore, the upper transmission shaft 31 and the connecting piece 33 can be separated from the clutch piece 35 when being subjected to the upward force, and the separation of the transmission shaft 30 is realized.

The user rotates the dough kneading cylinder 50 clockwise so that the cap 54 of the inverted T-shaped connecting rod 53 under the dough kneading rod 50 is positioned at the circular hole of the flange 51, applies an upward force to the dough kneading cylinder 50, separates the dough kneading cylinder 50 from the flange 51, and takes out the dough from the dough kneading cylinder 50 and cleans the dough kneading cylinder 50.

After the dough kneading cylinder 50 is cleaned, the user mounts the dough kneading cylinder 50 on the flange 51 in the reverse order of removing the dough kneading cylinder 50; then, a user applies a downward force to the upper body 10, the gas spring begins to contract due to the downward force, the upper body 10 and the lower body 20 begin to be closed, when the upper body 10 and the lower body 20 are to be closed, the user pulls the connecting rod 27 shared by the locking pins 22, so that the end a of the locking pin 22 moves towards the pulling direction until the upper body 10 and the lower body 20 are completely closed, the connecting rod 27 is released, the locking pin 22 moves under the action of the second elastic member 24, and the end a of the locking pin 22 is forced to be completely clamped with the locking hole 110 on the locking plate 19.

During the above-mentioned closing process of the upper body 10 and the lower body 20, the pin 34 and the inclined slot 36 on the coupling member 33 may occur in two ways: first, the pin 34 is just seated in the slot 36, the slot 36 is not subjected to the downward force of the pin 34, and the clutch 35 is not displaced downward; secondly, the pin 34 does not fall into the inclined groove 36, but falls into the clutch member 35 of the adjacent inclined groove 36, and at this time, because the upper transmission shaft 31, the coupling member 33 and the pin 34 are still subjected to downward force, the pin 34 applies a pressing downward force to the clutch member 35, the clutch member 35 further presses the first elastic member 38, and the clutch member 35 is displaced downward; in the second case, the dough mixer needs to be started next time, and the pin 34 rotates to fall into the chute 36 when the transmission shaft 30 is subjected to the rotating force under the action of the driving motor 13, and the process is as follows: there is no horizontal rotation force between the pin 34 and the inclined groove 36, i.e. the pin 34 rotates and the clutch 35 (the inclined groove 36) does not rotate until the bottom of the pin 34 rotates to the position above the opening of the inclined groove 36, because the clutch 35 is always subjected to the upward elastic force of the first elastic member 38, and at this time, the pin 34 does not apply downward force to the clutch 35, and the clutch 35 moves upward under the elastic force of the first elastic member 38, and moves relative to the pin 34, i.e. the clutch 35 moves upward, so that the pin 34 "falls" in the inclined groove 36, and the pin 34 is engaged with the inclined groove 36 tangentially.
