[0018] The utility model is further described and illustrated below in conjunction with the accompanying drawings and embodiments.

[0019] See also Figures 1 to 4 The present embodiment involves a mouse with an adjustable sliding extension block, comprising a mouse body 1 and an extension device, wherein a concave bottom shell 2 is fixedly connected to the bottom of the mouse body 1, and an adjustment device is arranged inside the concave bottom shell 2; a hand wheel 3 is arranged in the middle of one side wall of the concave bottom shell 2, and a rotating pin 7 is arranged at one end of the hand wheel 3; the hand wheel 3 is rotatably connected to the adjustment device through the rotating pin 7; when the user rotates the hand wheel 3, the rotating pin 7 will drive the adjustment device to perform corresponding mechanical movement, thereby realizing the sliding adjustment of the extension block 4 in the mouse.

[0020] A switch 18 is disposed on a side wall of the mouse body 1 close to the extension block 4 , and the switch 18 is used to lock or unlock the extension block 4 .

[0021] The four corners of the bottom of the concave bottom shell 2 are fixedly connected with foot pads 17, and the foot pads 17 are made of Teflon; the foot pads 17 ensure that the mouse can remain stable when the user is using it in gaming, drawing, etc., and reduce the possibility of sliding.

[0022] In this embodiment, the extension device includes an extension block 4, a sliding rod 5 and a moving block 6; the concave bottom shell 2 has two symmetrically arranged side walls on both sides thereof; one side wall of the two moving blocks 6 passes through the two sliding grooves 15 respectively and is fixedly connected to two sliding rods 5, and one end of the two sliding rods 5 extends to one side of the mouse body 1 and is fixedly connected to the extension block 4.

[0023] The moving block 6 can move forward and backward along the sliding groove 15 by cooperating with the sliding groove 15; the sliding rod 5 plays a supporting and guiding role, ensuring that the moving block 6 can slide out smoothly under the rotation of the hand wheel 3.

[0024] The extension block 4 is a sponge block with grooves; a side wall of the extension block 4 away from the mouse body 1 is provided with a silicone pad 16; the sponge block with grooves in the extension block 4 is used to support the wrist and reduce wrist fatigue; the silicone pad 16 provides additional anti-slip function when the user holds the mouse.

[0025] In this embodiment, the adjusting device comprises a first bevel gear 8, a rotating rod 9, a second bevel gear 10, a third bevel gear 11, a threaded rod 12, a fourth bevel gear 13, a nut block 14 and a slide groove 15; the adjusting device is slidably connected to the extending device.

[0026] The rotating rod 9 is arranged at the radial end of the concave bottom shell 2, and a second bevel gear 10 meshing with the first bevel gear 8 is fixedly connected to the rotating rod 9, and two symmetrically arranged third bevel gears 11 are fixedly connected to the rotating rod 9; the rotating pin 7 extends into the concave bottom shell 2 and is fixedly connected to the first bevel gear 8; the two threaded rods 12 are symmetrically arranged at the two lateral ends of the concave bottom shell 2; one end of the two threaded rods 12 is fixedly connected to a fourth bevel gear 13 meshing with the third bevel gear 11; the two threaded rods 12 are threadedly connected with nut blocks 14, and the opposite sides of the two nut blocks 14 are fixedly connected with moving blocks 6.

[0027] The user turns the hand wheel 3 to adjust the extension degree of the extension block 4 according to personal needs. Through the cooperation of a series of gear transmissions in the adjustment device and the extension device, the position of the extension block 4 is finally adjusted, thereby increasing the applicability and comfort of the mouse.

[0028] In order to improve the durability of the gear transmission so that it can withstand continuous use and repeated stress without breaking or falling off, the outer wall of the rotating rod 9 and the inner walls of the through holes of the second bevel gear 10 and the third bevel gear 11 are fixedly connected by welding.

[0029] Working principle of the utility model: when the user's wrist feels tired, it is necessary to adjust the extension degree of the extension block 4. The user rotates the hand wheel 3, drives the rotating pin 7 to rotate, and then drives the first bevel gear 8 to rotate. Since the first bevel gear 8 is meshed with the second bevel gear 10, it drives the rotating rod 9 to rotate, thereby driving the two third bevel gears 11 to rotate at the same time. Since the two third bevel gears 11 are respectively meshed with the two fourth bevel gears 13, they drive the two threaded rods 12 to rotate at the same time. Since the two threaded rods 12 are respectively threadedly connected with the two nut blocks 14, and the axial rotation of the nut block 14 is limited by the slide groove 15, the two nut blocks 14 are forced to move synchronously, thereby driving the extension block 4 fixedly connected to the extension rod 5 to move, and the distance between the mouse body 1 and the extension block 4 is adjusted, thereby realizing the extension degree of the extension block 4 of the device. The operation is simple and suitable for people with different degrees of wrist fatigue.

[0030] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
