Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1-3 The first embodiment shown is a throttle knob cover mounting mechanism, comprising a shell 1, an opening is provided at the bottom of the shell 1, positioning screw holes are provided at the lower end edges of both sides of the shell 1, electric push rods 2 are provided at both ends of the lower side of the shell 1, a support plate 3 is slidably connected to the front of the shell 1, a loading piece is provided on the back of the shell 1, an extended end of the electric push rod 2 is fixedly connected to the back edge of the support plate 3, and a movable groove is provided near the extended end of the electric push rod 2 of the shell 1; a knob cover assembly 4 for the throttle is placed on the upper end of the support plate 3;

[0020] A cylinder assembly 5 is provided on the top of the shell 1, and a movable plate 6 is connected to the bottom of the cylinder assembly 5 near the inner end of the shell 1. A rotating frame 7 is rotatably connected to the middle of the movable plate 6. A first motor 8 is provided on the left side of the rotating frame 7. A bidirectional screw 9 is rotatably connected to the middle of the rotating frame 7. Both sides of the bidirectional screw 9 are respectively threadedly connected to a movable frame 10 that is slidably connected to the rotating frame 7. A mounting member 11 is connected to the bottom of the movable frame 10. The output end of the first motor 8 is coaxially fixedly connected to the bidirectional screw 9. The mounting member 11 is composed of a micro motor and a mounting rod. The micro motor is fixedly connected to the movable frame 10, and the output end of the micro motor is coaxially fixedly connected to the mounting rod.

[0021] The movable frame 10 is slidably connected with a clamping rod 12 near the upper end of the mounting member 11, and a spring 13 is fixedly connected to the end of the movable frame 10 near the clamping rod 12. The clamping block fixedly connected to the spring 13 is fixedly connected to the end of the clamping rod 12 near the knob and cover assembly 4, and the clamping block fits the knob and cover assembly 4. The clamping rod 12 is fixedly connected to a stopper away from the clamping block end; a second motor 14 is provided on the upper side of the movable plate 6, and a gear assembly 15 is connected to the output end of the second motor 14. An air pump 16 is provided on the upper side of the shell 1, and a conduit 17 is fixedly connected to the air outlet end of the air pump 16; the second motor 14 is coaxially fixedly connected to the driving gear in the gear assembly 15, and the driven gear in the gear assembly 15 is coaxially fixedly connected to the top of the rotating frame 7. The first motor 8 and the second motor 14 are both servo motors;

[0022] Start the cylinder assembly 5, which drives the moving plate 6, the rotating frame 7, the first motor 8, the bidirectional screw 9, the movable frame 10, the mounting piece 11, the clamping rod 12, the spring 13, the second motor 14, the gear assembly 15, and the knob cover assembly 4 to move downward. After the knob cover assembly 4 is aligned with the mounting groove of the mounting steel plate, the angle of the knob cover assembly 4 is adjusted by the gear assembly 15. After the mounting screw at the edge of the knob cover assembly 4 is aligned with the screw hole at the axial end of the mounting groove, the knob cover assembly 4 is inserted into the mounting groove. At this time, the mounting screw contacts the screw hole, and the reaction force of the mounting steel plate causes the upper end of the mounting screw to contact the bottom of the mounting rod in the mounting piece 11. The mounting screw is driven to rotate by the micro motor and the mounting rod. After the mounting screw is screwed into the screw hole, the mounting steel plate and the knob cover assembly 4 are installed.

When the air pump 16 is started, the air pump 16 draws in external gas through the exhaust pipe, and then the gas is ejected through the conduit 17, the bellows, the rotating frame 7, the ventilation groove, and the ventilation filter plate. The gas ejected from the jet filter plate blows on the knob cover assembly 4, the bidirectional screw 9, and the movable frame 10, so as to promote the falling off of impurities attached to the surfaces of the three.

[0025] 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.

[0026] When in use, the user places the knob cover assembly 4 to be installed on the support plate 3 through the external loading piece, and starts the second motor 14. The second motor 14 drives the rotating frame 7, the first motor 8, the bidirectional screw 9, the movable frame 10, the mounting member 11, the clamping rod 12, and the spring 13 to rotate through the gear assembly 15. After the mounting member 11 is rotated to a suitable position, the second motor 14 is turned off, and the first motor 8 is started. The first motor 8 drives the two groups of movable frames 10, the mounting member 11, the clamping rod 12, and the spring 13 to move toward the knob cover assembly 4 through the bidirectional screw 9. The clamping rod 12 cooperates with the spring 13 and the clamping block to clamp the knob cover assembly 4. When the bottom of the mounting member 11 is located just above the mounting screw on the edge of the knob cover assembly 4, the first motor 8 is turned off, and the support plate 3 is driven to separate from the bottom of the knob cover assembly 4 through the electric push rod 2. After the steel plate to be installed is transported to a suitable position at the lower end opening of the shell 1;

[0027] Start the cylinder assembly 5, which drives the moving plate 6, the rotating frame 7, the first motor 8, the bidirectional screw 9, the movable frame 10, the mounting piece 11, the clamping rod 12, the spring 13, the second motor 14, the gear assembly 15, and the knob cover assembly 4 to move downward. After the knob cover assembly 4 is aligned with the mounting groove of the mounting steel plate, the angle of the knob cover assembly 4 is adjusted by the gear assembly 15. After the mounting screws at the edge of the knob cover assembly 4 are aligned with the screw holes at the axial ends of the mounting grooves, the knob cover assembly 4 is inserted into the mounting grooves. At this time, the mounting screws are in contact with the screw holes, and the reaction force of the mounting steel plate makes the upper ends of the mounting screws contact with the mounting piece 11. The mounting screws are driven to rotate by the mounting piece 11. After the mounting screws are screwed into the screw holes, the mounting steel plate and the knob cover assembly 4 are installed, so that each link is reset.
