[0036] With the above structure, the key button 21 faces the control hole 12 in the initial position, and since the key button 21 is at least partially elastic, it can be elastically deformed after being pressed, at which time pressing the key button 21 can make it deform to press the pressing sensing member 32, so that the pressing sensing member 32 can sense the pressing signal; in addition, since the key button 21 can slide relative to the handle body 1 under the action of an external force, the position is changed by sliding, and after losing the external force, it can be restored to the initial position by the restoring member 22; the moving position is sensed by the position sensing member 31, thereby forming two kinds of signals of pressing and moving, so as to form different instructions by different combinations of the two kinds of signals (including but not limited to direction, number and sequence, etc.), and then form different mode controls, facilitating control.

[0037] It can be understood that the control assembly 3 further comprises a control board 33 (PCB board) connected to the position sensing member 31 and the pressing sensing member 32, and the control board 33 is connected to components such as motors and drive shafts.

[0038] As Figure 1 and Figure 2As shown in the figure, in some embodiments, the sealing member 4 is blocked in the control hole 12, and since the key button 21 needs to be pressed to generate deformation, in order to avoid the blockage of the sealing member 4, the sealing member 4 is also elastic, so that when the key button 21 is pressed, the sealing member 4 can also be deformed. Further, in order to ensure the sealing, the sealing member 4 can be integrally formed with the handle body 1. Exemplarily, the sealing member 4 can be but not limited to made of rubber, silica gel and the like. The pressing sensing member 32 can be selected from a micro switch or a reed switch and the like.

[0039] As shown in the figure, Figure 1 and Figure 2 in some embodiments, the restoring member 22 includes two magnets, one of which is arranged on the key button 21, and the other is fixed in the inner cavity 11, so that after losing external force, the two magnets can attract each other, so that the key button 21 returns to the original position. As shown in the figure, Figure 2 and Figure 4 further, in order to facilitate installation, the key button 21 includes a shell 211 and a pressing soft body 212, the shell 211 is annular, the shell 211 surrounds the pressing soft body 212, the pressing soft body 212 has elasticity, and is used for pressing the pressing sensing member 32; the magnet is annular, surrounds the outer periphery of the pressing soft body 212, and is clamped between the pressing soft body 212 and the shell 211 for fixation. And the other magnet can surround the outer periphery of the pressing sensing member 32. Exemplarily, the magnet is a magnet, and the position sensing member 31 is a Hall element, so that when the key button 21 moves with the magnet, the Hall element can sense the change of the magnetic field to sense the position change of the key button 21.

[0040] Further, as shown in the figure, Figure 2 and Figure 5 in order to facilitate pressing, the pressing soft body 212 includes a slot-shaped body part 2121, the slot of the body part 2121 faces the control hole 12, the body part 2121 is connected with a pressing column 2122, the pressing column 2122 is connected to the slot bottom of the body part 2121, and the pressing column 2122 abuts on the sealing member 4, so that when pressing, smaller force can be used to make the body part 2121 deform, drive the pressing column 2122 abut against the sealing member 4, and further press the pressing sensing member 32.

[0041] Further, as shown in the figure, Figure 3 and Figure 4As shown, in order to facilitate the movement of the key button 21, the shell 211 is provided with a sliding groove 213 in one of the handle bodies 1, and the other is provided with a sliding block 214 slidingly connected to the sliding groove 213, and the stability is improved by the combination of the sliding block 214 and the sliding groove 213. Specifically, the handle body 1 is provided with a retaining ring 13, which is circumferentially arranged on the outer periphery of the control hole 12, and the opposite sides of the retaining ring 13 are provided with the sliding groove 213, and the opposite sides of the shell 211 are provided with the sliding block 214. It can be understood that the distance of the retaining ring 13 along the extension direction of the sliding groove 213 is greater than the size of the key button 21, so as to provide displacement space for the key button 21.

[0042] In other embodiments, the return member 22 comprises an elastic member, one end of the elastic member is connected to the key button 21, and the other end is connected to the handle body 1, the compression direction of the elastic member is the same as the movement direction of the key button 21 along the handle body 1, so that the elastic member can accumulate potential energy during the movement of the key button 21, and return to the original position by the elastic potential energy of the elastic member after losing external force. Exemplarily, the elastic member can be a spring or an elastic rubber, which can be connected between the sliding block 214 and the retaining ring 13.
