The invention discloses an arbitrary point-pressing panel switch which comprises a switch base, wherein a switch function element is arranged in the switch base, and a penal switch button which can drive the switch function element to work is arranged on the switch base. The arbitrary point-pressing panel switch is characterized in that a linkage device is arranged between the penal switch button and the switch base, and can enable the whole panel switch button to downwards move when the arbitrary point on the surface of the panel switch button is pressed. The invention aims to overcome the defects in the prior art, and provides the arbitrary point-pressing panel switch which has a simple structure, and can enable the whole panel switch button to downwards move so as to effectively trigger the switch.

The invention discloses a height adjusting device of a work chamber of a forklift. The height adjusting device comprises a bottom plate, wherein rack fixing seats are fixedly connected to the top of the bottom plate, and the tops of the rack fixing seats are fixedly connected with supporting rods; a first rack and a second rack are fixedly connected to the tops of the supporting rods correspondingly, a first motor fixing frame is fixedly connected with the outer wall of the first rack, a second motor fixing frame is fixedly connected with the outer wall of the second rack, a first motor is fixedly connected with the interior of the first motor fixing frame, and a second motor is fixedly connected with the interior of the second motor fixing frame; and an output shaft of the first motor andan output shaft of the second motor are rotationally connected with deceleration connectors respectively, and output shafts of the deceleration connectors are rotationally connected with first belt wheels. The invention relates to the technical field of vehicle machinery. According to the height adjusting device of the work chamber of the forklift, the problem of height adjustment of the work chamber of the forklift is solved, a driver can still see the road ahead when the forklift is loaded with too high objects, the working safety is guaranteed, the working efficiency is improved, and the comfort of the driver is improved.

The invention discloses an infusion support for the pneumology department, which comprises a movable support, wherein an annular support is fixedly connected to the bottom of the movable support. According to the invention, the movable frame is lifted, the movable frame enables the top end of a clamping head to push the inner side end of a rotating frame to move upwards through a pull rod and a bottom plate, the rotating frame rotates with the clamping rod as the circle center and pressurizes an elastic piece in a second rotating groove at the same time, and universal wheels at the outer side ends of the rotating frame gradually rotate to the bottom of the bottom plate. According to the infusion support, the fast moving effect on the ground is improved through the universal wheels, when the movable frame moves downwards, the elastic piece on the inner side of the second rotating groove enables the rotating frame to rotate, the bottom plate is prevented from colliding with the universal wheels in the downward moving process, then the collision damage to the whole infusion support is reduced, after the bottom surface of the bottom plate is flush with the side edge of the bottom of the annular frame, the stability of the whole infusion support in the placement process is guaranteed through cooperation of the bottom plate and the annular frame, and the infusion support can be conveniently moved along with a child.
