In an embodiment of the present application, at least one layer of wear-resistant smooth film 302 is further included; the wear-resistant smooth rubber sheet 302 is arranged between the middle shell 200 and the base 300.

In a specific embodiment, the base 300 is further provided with a layer of wear-resistant smooth film 302; the wear-resistant smooth rubber sheet 302 is arranged between the base 301 and the middle shell 200.

In an embodiment of the present application, the first PCB 101 has a micro switch 204 for triggering a left button of a mouse; the button of the microswitch 204 corresponds to the middle shell 200; or, the middle shell 200 is provided with a second PCB 201; a microswitch 204 for triggering the function of the left mouse button is arranged on the second PCB 201; the button of the microswitch 204 corresponds to the upper shell 200; the microswitch 204 is triggered when the top shell 100 is displaced downward and/or springs upward relative to the middle shell 200.

In an embodiment of the present application, a first PCB 101 is disposed in the upper case 100; the upper surface of the upper shell 100 is also provided with a plurality of function keys; each function key is correspondingly connected to a different induction electrode on the first PCB 101; the sensing electrode is configured to output a corresponding function instruction in response to the function key.

In the above embodiment, the upper surface of the upper casing 100 is further provided with a plurality of function keys; the function keys include a center key 106, a right key 105, a SET key 109, a DPI key 108, and a jog key 107; the middle key 106, the right key 105, the SET key 109, the DPI key 108, and the jog key 107 correspond to different sensing electrodes on the first PCB, respectively.

As an example, the implementation process is as follows, the relative movement between the photoelectric movement sensor 202 and the cursor movement sensing surface (i.e., the cursor sensing surface 301) generates a change of the coordinate value, and then detects whether the cursor movement sensing key or the middle mouse key or the right mouse key is activated, and if so, the cursor movement is implemented. When the finger is released, the cursor movement sensing key 110, the middle key 106 and the right key 105 are not activated, and the photoelectric movement sensor 202 and the cursor sensing surface 301 move relatively, so that the cursor movement is stopped. The base 300 and the middle shell 200 are a movable mechanism, the finger moves the middle shell 200, the middle shell 200 and the base 300 move relatively, the base 300 of the device is static relative to the working table, and the finger automatically moves back to the circular center position through the clip spring 203 after being released. Double-click is implemented, and the cursor can be automatically moved to a designated position on the display screen by the cursor movement sensing key 110. The moving method comprises the following steps: sending a larger X and Y coordinate value to move the cursor to a certain corner of the display screen, and then sending a relative value coordinate relative to the corner to move the designated position. The jump of the storage automatic cursor to the specified position coordinates is regulated by the SET key 109+ the middle key 106 or the right key 105. By means of the SET key 109, the finger release automatically moves the cursor to a specified position after the opening and closing of the cursor movement. The wheel adjustment, center key 106 and right key 105, DPI key 108 is achieved by capacitive sensing. The left mouse button is realized by the action of the mechanical button operated up and down by the upper shell 100 and is reset by the cylindrical spring 103. Wear-resistant smooth films 302 are adhered to two sides between the base 300 and the middle shell 200, so that the resistance in moving is reduced.
