In the prior art, the traditional pointing stick product mostly adopts a pressure sensor to identify the action of a finger, and the principle is that the pressure sensor generates different voltages by pressing the finger so as to judge the position of the finger, thereby converting the position into the movement direction of a mouse pointer; the pointer movement angle subdivision device has the advantages that the pointer movement angle subdivision can be realized, the resolution of the mouse is within 10 degrees, and meanwhile, the pointer movement speed is adjusted through the pressure; however, such a pointing stick using a pressure sensor has the disadvantage of being too costly to be used in a very high, low and wide temperature range, and not in a hot and humid environment.
In addition, the pointing stick in the prior art is difficult to cope with special environments such as humid, mold, greasy industrial environments, chemical corrosion and the like in the fields of industry, medical treatment, high technology and the like.
Disclosure of Invention
The invention aims to provide a high-resolution button type mouse button so as to make up for a plurality of defects of a pointing stick product in the prior art.
In order to achieve the above purpose, the present invention adopts the following technical scheme.

wherein, the top surface of the basal body is integrally formed with a mouse button, a left mouse button and a right mouse button which are respectively arranged at the left side and the right side of the mouse button; the mouse button system penetrates downwards into the cylindrical structure of the base body, the cylindrical surface of the mouse button system is provided with a skirt edge which is in transition with the base body in a ring manner, and the base body provides elastic support for the mouse button through the skirt edge; the bottom surface of the mouse button is concentrically provided with a downward protruding round table, and the end surface of the round table is covered with a conductive layer which is in clearance fit with the top surface of the PCBA control board;
the PCBA control board is provided with a plurality of signal electrodes which are distributed symmetrically at equal angular intervals relative to the axis of the mouse button on the top surface, and each signal electrode is respectively arranged along the radial direction of the circumference; the PCBA control board is also provided with a plurality of common electrodes which are distributed at equal angles and symmetrically at intervals relative to the axis of the mouse button, and each common electrode is also respectively arranged along the radial direction of the circumference; the common electrodes and the signal electrodes are alternately distributed, and the common electrodes are mutually short-circuited; when the mouse button is pressed to cause the round table to incline to contact the PCBA control board, the signal electrode in the inclined direction of the round table is in short circuit with the public electrode through the conducting layer;
wherein, the PCBA control board is provided with an MCU chip to scan each signal electrode and identify the signal electrode short-circuited with the common electrode; the MCU chip outputs a pointer control signal to the computer through the USB cable, and the pointer control signal drives the mouse pointer to move in a corresponding direction in the circumference by referring to the signal electrode which is in short circuit with the common electrode;
the top surface of the PCBA control board is provided with key circuits respectively corresponding to a left mouse button and a right mouse button, and the left mouse button and the right mouse button trigger the corresponding key circuits respectively when pressed; the MCU chip outputs a key control signal for driving the mouse pointer to click to the computer through the USB cable corresponding to the triggered key circuit.
According to the technical scheme, because the silica gel surface cover is integrally formed by silica gel, the top surface of the PCBA control panel is matched with the bottom surface of the substrate of the silica gel surface cover in a watertight manner, the high-resolution button-type mouse button has the effects of wear resistance, tear resistance, interference resistance, chemical corrosion resistance and gas-liquid invasion resistance, can normally work in special environments such as wet, mould, greasy dirt industrial environments and chemical corrosion, can be applied in low-50 ℃ and high-temperature 80 ℃ environments, has more handfeel in operation, and improves operability, durability, interference resistance and damage resistance.
Unlike available technology, the high resolution button mouse button of the present invention has no pressure sensor, and when the button is pressed to tilt the circular truncated cone relatively to the axis, at least one signal electrode is short connected to the common electrode via the conducting layer and the MCU chip is used to scan and identify the signal electrode short connected to the common electrode; and the MCU chip outputs a pointer control signal to the computer through the USB cable, and the pointer control signal drives the mouse pointer to move in the direction of the pointing angle corresponding to the signal electrode shorted with the common electrode in the circumference.
