The first adjusting member 4 includes a bidirectional screw 41 which is rotatably connected to the bottom plate 1 and threadedly connected to the two groups of first sliding frames 31. The front side of the bidirectional screw 41 is fixedly connected to a first shifting block 42;

[0027] The second adjusting member 5 is installed on the bottom plate 1 and is used for longitudinal adjustment of the second sliding frame 33. The second adjusting member 5 includes a one-way screw 51 rotatably connected to the bottom plate 1. The one-way screw 51 is longitudinally threadedly connected to a limit frame 53 slidably connected to the two sets of second sliding frames 33. A second shifting block 52 is installed on the top of the one-way screw 51;

[0028] A vertical sound insulation board 6 is installed on the right side of the bottom plate 1; the motor body 2 is fixedly connected to the bottom plate 1 by screws, and an array of fixing blocks is provided at the edge of the bottom plate 1, and a through screw hole is longitudinally provided inside the fixing block;

[0030] like Figure 1-4 The second embodiment shown is mainly different from the first embodiment in that:

[0031] The magnets 37 at the edges of the two groups of horizontal sound insulation boards 36 have opposite magnetic properties. The two groups of horizontal sound insulation boards 36 are provided with baffles at the ends away from the magnets 37. The movable frame 35 is located between the baffles and the magnets 37. The two groups of horizontal sound insulation boards 36 are connected by fitting together the two groups of magnets 37 with opposite magnetic properties, which can soundproof and protect the upper side of the motor body 2. The baffles and the magnets 37 can prevent the horizontal sound insulation boards 36 on the movable frame 35 from falling off, so that the magnets 37 on the two groups of horizontal sound insulation boards 36 are separated. The horizontal sound insulation boards 36 are moved to open the upper end of the bottom plate 1, so that the user can replace the motor body 2 at the upper end of the bottom plate 1.

[0032] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0033] When in use, the user moves the horizontal sound insulation board 36 to separate the magnets 37 on the two groups of horizontal sound insulation boards 36, and continues to move the horizontal sound insulation board 36 to open the upper end of the bottom plate 1, install the motor body 2 on the bottom plate 1, and rotate the first dial block 42. The first dial block 42 drives the bidirectional screw 41 to rotate, and the bidirectional screw 41 drives the two groups of first sliding frames 31, the second sliding frames 33, the sound absorbing strip 34, and the movable frame 35 to move toward the two sides of the motor body 2, wherein the two groups of second sliding frames 33 slide along the limit frame 53, and after the first sliding frame 31 and the second sliding frame 33 are close to the side of the motor body 2, the first dial block 42 is stopped, and the second dial block 52 is rotated. The second dial block 52 drives the one-way screw 51 to rotate, and the rotating one-way screw 51 drives The movable limit frame 53, the two sets of second sliding frames 33, the movable frame 35, the horizontal sound insulation board 36, and the magnet 37 move upward. After the horizontal sound insulation board 36 is higher than the top height of the motor body 2, the one-way screw 51 is stopped, and the horizontal sound insulation board 36 in the movable frame 35 is slid, so that the magnets 37 on the edges of the two sets of horizontal sound insulation boards 36 are re-attached and adsorbed. At this time, the two sets of horizontal sound insulation boards 36 block the upper end of the motor body 2, so that the motor body 2 is electrically connected to the external controller and its output end is connected to the corresponding driving component. When the motor body 2 is operating, the horizontal sound insulation board 36, the vertical sound insulation board 6, the first sliding frame 31, and the several sets of sound absorbing strips 34 on the inner wall of the second sliding frame 33 respectively absorb the noise generated by the operating motor body 2.
