A switch (7) is arranged at the bottom of the mouse and an anti-slipping pad (8) is installed at the bottom of the mouse. The CAD special wireless mouse is characterized in that the left front curved surface and the right front curved surface of the mouse are fit with curves of five fingers when a right palm surface is perpendicular to a desktop and the five fingers are naturally curved; a cursor trackball (2) is installed on the left front curved surface at a position corresponding to the thumb of the right hand; and a mouse left key (5) is installed on the right front curved surface at a position corresponding to the index finger of the right hand, a mouse middle key (4) is installed on the right front curved surface at a position corresponding to the middle finger of the right hand, and a mouse right key (3) is installed on the right front curved surface at a position corresponding to the ring finger of the right hand. The CAD special wireless mouse has the advantages that the overall design complies with ergonomics, the use comfort of the mouse is improved and the wrist fatigue of a CAD drawer is reduced.

Description

CAD dedicated wireless mouse

technical field

The utility model relates to a computer accessory, in particular to a special wireless mouse for CAD.

Background technique

When using CAD software for design work, it usually requires a long time of mouse operation. When a designer operates a traditional mouse, the palm of the hand is basically parallel to the desktop, which usually compresses the nerves under the wrist, and the mouse needs to be moved frequently to adjust the position of the cursor, so the wrist and fingers often feel sore, and after a long time, they may even find themselves The carpal bone of the child is protruding and the palm is deformed, which is commonly known as "mouse hand". In addition, most CAD software requires the middle mouse button to be operated frequently. The traditional mouse uses a scroll wheel instead of the middle mouse button. Due to the small contact surface, it is usually laborious to press, and the fingers are prone to fatigue.

Utility model content

The utility model provides a special wireless mouse for CAD based on ergonomics to solve the deficiencies of the prior art.

A special wireless mouse for CAD is composed of a mouse body and a USB wireless connector. There is a battery box inside the mouse, a switch is provided at the bottom of the mouse, and an anti-slip gasket is installed; it is characterized in that: the surface of the mouse body is divided into a left front curved surface, The right front curved surface and the rear curved surface; the shapes of the left front curved surface and the right front curved surface are consistent with the bending state of the five fingers on the vertical desktop of the right palm when they are naturally bent and relaxed; a cursor trackball is installed on the left front curved surface corresponding to the right thumb; the above right front curved surface A left mouse button is installed at the place corresponding to the index finger of the right hand, a middle mouse button is installed at the place corresponding to the middle finger of the right hand, and a right mouse button is installed at the place corresponding to the ring finger of the right hand.

Detailed ways

As shown in Fig. 1, the front part of the upper surface of the mouse can be divided into two curved surfaces. The right side is a curved surface with a large inclination angle, including three mouse buttons: right mouse button 3, middle mouse button 4 and left mouse button 5. A cursor trackball 2 is installed on the left side to control the position of the computer cursor. There are embedded battery box 6 and switch 7 on the bottom surface of the mouse among Fig. 3 . When in use, the USB wireless connector 10 is connected to a computer to realize communication between the mouse and the computer. Mouse battery case 6 installs a No. 5 battery, and switch 7 is turned on. The position of the cursor is controlled by the trackball 2, and the three mouse buttons are used to perform operations related to CAD drawing.

When the USB wireless connector is connected to the USB interface of the computer for drawing, the trackball can be controlled by the thumb, and the three mouse buttons of the mouse can be controlled by the index finger, middle finger and ring finger. The palm surface and the right side of the mouse basically fit, and because the right side of the mouse and the bottom surface of the mouse form a large inclination angle, when holding the mouse, it will not compress the nerves under the wrist, effectively avoiding "mouse hand". Since most CAD software requires the middle mouse button for related operations, the CAD dedicated wireless mouse is designed with a middle mouse button that does not rely on the scroll wheel, and the button is easy and flexible, thereby reducing the fatigue of the fingers. In addition, the trackball combines wireless connection design with an integrated curved surface shell, which is easy to hold and does not require work surface support, adapting to various working environments, and can easily perform tasks such as mobile presentations and teaching. Combining the above design features, the design of the dedicated wireless mouse for CAD is more user-friendly, which improves the comfort of using the mouse and protects the physical and mental health of CAD drafters to the greatest extent.
