The invention discloses a chemical device inspection maintenance teaching device which comprises an operating console. A chemical device body is arranged on the top side of the operating console. Twosupporting legs are fixedly welded on the bottom side of the operating console. The supporting legs are arranged obliquely. An adjusting rod is movably arranged on one end, which is away from the operating console, of each supporting leg. A fixed block is fixedly arranged on one end, which is away from a supporting leg, of each adjusting rod. A universal wheel is fixedly arranged on the bottom side of each fixed block. A height adjustment mechanism which adjusts the height of the operating console is arranged between the supporting legs and the adjusting rods. The height adjustment mechanism comprises a slide groove arranged on one side, which is away from the operating console, of each supporting leg. One end, which is away from a fixed block, of each adjusting rod is slidably arranged ina slide groove. According to the invention, a number of operating consoles can be stably combined and arranged, which facilitates the teaching of single or multiple chemical devices; and the height of the operating console can be adjusted, which facilitates combination installation, facilitates the movement of the operating console and meets various height operating demands.

The invention discloses a mouse. The mouse comprises a bottom box, a winding rod, a mouse body, movable keys, an air blowing opening and a supporting frame, the winding rod is installed at the top of the bottom box in a penetrating mode, the bottom end of the winding rod is installed on the inner side of the bottom of the bottom box, the mouse body is installed at the top of the bottom box, and the mouse body is located at one side of the winding rod; the movable keys are mounted at one end of the mouse body in an embedded mode, the air blowing opening is formed in the top of the mouse body and located at one end of the movable key, the supporting frame is mounted at the top of the bottom box through bolts, and the supporting frame is located at the side, away from the winding rod, of the mouse body. The movable keys are guided to move through a first embedding slide way and a second embedding slide way, a user can conveniently adjust the position relation between the mouse body and the movable keys, the user can conveniently adjust the size of the device, and the mouse is used for adapting to the sizes of different hands.

The invention belongs to the technical field of transmissions and particularly relates to a simple manual adjusting transmission based on four connecting rod drive. The simple manual adjusting transmission comprises an installing shell, a first oscillating bar, a second oscillating bar, an input shaft, a third oscillating bar, an output shaft, a fourth oscillating bar and a fifth oscillating bar.When people use the transmission of the design, firstly the relative position of a sliding block and the first oscillating bar is adjusted manually; then the input shaft is driven to rotate and can drives the fourth oscillating bar to rotate around the axis of the input shaft; the fourth oscillating bar rotates to drive the fifth oscillating bar to oscillate; the fifth oscillating bar rotates to drive the first oscillating bar to rotate around the axis of an adjusting bar; the first oscillating bar rotates to drive the second oscillating bar to oscillate; the second oscillating bar oscillate to drive an arc driving plate to oscillate around a fixed shaft; the arc driving plate oscillate to drive a second gear to rotate; and the second gear rotates to drive an output shaft to rotate. The transmissions achieves speed change through four connecting rod drive and is simple in design structure, convenient to replace and wide in use range.

The invention discloses an adjusting mechanism and a household appliance comprising the adjusting mechanism. The adjusting mechanism comprises at least one adjusting hole and at least two spaced fixedholes arranged on one of a first part and a second part, at least three matching holes arranged on the other one of the first part and the second part, and at least two connecting parts, wherein theat least three matching holes comprise at least one first matching hole matched with the at least one adjusting hole, and second matching holes matched with the at least two fixed holes; when the holecenters of any one fixed hole and the corresponding second matching hole are overlapped, the hole centers of the rest fixed holes and the corresponding second matching holes form gaps in the adjusting direction; one connecting part penetrates through the fixed hole and the second matching hole with the overlapped hole centers; and the other connecting part penetrates through the adjusting holes and the first matching holes to fix the first part and the second part.
