[0026] The disassembly and assembly assembly 2 comprises an adjusting unit and a reinforcing unit;

[0027] The adjusting unit is used for realizing the horizontal movement adjusting operation of the movable end plate 104;

[0028] The reinforcing unit is used for reinforcing the position of the movable end plate 104;

[0029] The adjusting unit comprises a screw 201, a hand worm gear and worm reducer 202, a hand wheel 203 and a linkage shaft 204;

[0030] Two screw rods 201 are arranged at the upper and lower ends of the guide rods 102, and the two screw rods 201 penetrate the two ends of the movable end plate 104 and are rotationally connected with the fixed end plate 101 and the upper and lower ends of the column 103, and the movable end plate 104 is in threaded connection with the two screw rods 201;

[0031] One end of the screw rod 201 penetrates the column 103 and is fixedly connected with the output end of the hand-operated worm and gear reducer 202, and the hand-operated worm and gear reducer 202 is fixedly installed at the end of the column 103 away from the guide rod 102, and the linkage shaft 204 is arranged between the two hand-operated worm and gear reducers 202 and is fixedly connected with the worm extension rods in the two hand-operated worm and gear reducers 202;

[0032] The hand wheel 203 is arranged above the top hand-operated worm and gear reducer 202 and is fixedly connected with the input end of the upper hand-operated worm and gear reducer 202, and when the hand wheel 203 is rotated, the synchronous rotation of the two screw rods 201 is realized through the transmission of the two hand-operated worm and gear reducers 202, and then the horizontal movement of the movable end plate 104 is realized;

[0036] In daily use, the initial state of the locking nut 205 is tightly attached to the movable end plate 104, that is, the movement of the movable end plate 104 in the direction of the column 103 is limited, and at this time, if the hand-operated worm and gear reducer 202 is rotated, it cannot be rotated, thereby ensuring the stable compression of the movable end plate 104 on the heat exchange plate and avoiding loosening

[0037] When the heat exchange plate needs to be disassembled, cleaned or replaced, the operation steps are as follows:

[0038] First, the tool (for example: wrench) on the locking nut 205 is loosened to release the pressure on the movable end plate 104, and then the locking nut 205 is manually rotated to move closer to the column 103 (it should be noted that the final locking nut 205 is close to the column 103 but not closely combined with the column 103, and when the locking nut 205 is rotated, the screw rod 201 remains in a non-rotating state under the self-locking function of the hand-operated worm gear reducer 1).

[0039] Then, the hand wheel 203 is rotated, and the hand wheel 203 drives the two hand-operated worm gear reducers 202 to operate synchronously through the cooperation of the connecting shaft 204, and the output end of the hand-operated worm gear reducer 202 drives the screw rod 201 to rotate, so that the movable end plate 104 can be moved horizontally under the cooperation of the threaded structure, and the movable end plate 104 is moved towards the column 103, so that the pressure on the heat exchange plate is released, and then the heat exchange plate can be disassembled and replaced (it should be noted that the hand-operated worm gear reducer 202 is a common hand-operated worm gear reducer in the market, and the hand-operated worm gear reducer is a widely used power transmission mechanism, so the internal structure is not described here).

[0040] Please refer to Figs. 1-3 , one end of the screw rod 201 away from the column 103 penetrates the other end face of the fixed end plate 101 and is fixedly connected with a polygonal block 206.

[0041] In this embodiment, when the hand-operated worm gear reducer 1 is removed due to failure, the polygonal block 206 can be rotated by an external tool (for example: electric wrench) to drive the screw rod 201 to rotate.

[0042] Please refer to Figs. 1-3 , the threads of the two screw rods 201 have the same direction and pitch, the movable end plate 104 is provided with screw holes matched with the two screw rods 201, and the movable end plate 104 is provided with limiting sliding holes matched with the outer wall of the guide rod 102.
