The invention relates to the technical field of stationery, in particular to a portable writing board for an English class. Comprising a box body and a rotating frame, the box body and the rotating frame are connected through an angle adjusting mechanism, a supporting mechanism is arranged on the bottom wall of the box body, a steering mechanism is arranged on the bottom wall of the box body, a cleaning mechanism is arranged on the end wall of the rotating frame, and the surface of the writing board can be cleaned through movement of the cleaning mechanism; the writing board can be lifted, writing is facilitated, and the surface of the writing board can be wiped and cleaned; through movement of the mechanism, the angle of the writing board can be adjusted, and writing on the writing board is facilitated; through movement of the mechanism, steering adjustment of the writing board can be achieved, the writing board can be conveniently rotated to a proper position, and writing is facilitated.

The invention provides a laparoscopic surgical forceps with a multifunctional lockable bending angle of the forceps head, which relates to the technical field of medical equipment, and solves the problem that the absorption and removal of waste liquid in the abdominal cavity cannot be achieved through structural improvement while realizing the shearing action. , and the bending of the pipette cannot be avoided in the process of realizing absorption and removal; the suspension placement cannot be realized through structural improvement, and the suspension placement structure cannot realize the problem of collecting water droplets. A multifunctional laparoscopic surgical forceps capable of locking the bending angle of the forceps head comprises a surgical forceps seat body; the surgical forceps seat body is made of plastic material. Because the base is a rectangular box-shaped structure, and the base constitutes the surgical forceps seat body and the sweat drop collection structure on the pressing seat, so when the sweat droplets or moisture dripping from the outside of the surgical gloves due to temperature difference can be collected by the base, thereby avoiding dripped into the patient's abdominal cavity.

The wet-type and dust-free blackboard cleaner comprises a fixed dismantling part, a single-direction and single-step controlling part and a wiping and cleaning part, wherein the fixed dismantling part comprises a fixed sleeve, a connecting block and a mounting spring, the connecting block is arranged in the fixed sleeve, the mounting spring is arranged between the fixed sleeve and the groove of the connecting block, a sliding key is fixedly installed on the connecting block and matched with a key groove in the fixed sleeve, and a fixed key is fixedly installed on the connecting block; the single-direction and single-step controlling part comprises a pawl, a ratchet wheel, a connecting spring and a bearing, a boss is arranged on the pawl, ratchet wheel grooves are formed in the ratchet wheel at 90-degree intervals, the ratchet wheel grooves are matched with the pawl, a gap is reserved between the highest point of the ratchet wheel grooves and the inner wall of the fixed sleeve, and the gap is matched with the boss of the pawl; the wiping and cleaning part comprises a water storing pipe, a piece of dry felt cloth and a piece of wet felt cloth, the water storing pipe is fixedly connected with the ratchet wheel in a sealing mode, and the wet felt cloth is fixedly installed on the water storing pipe through an open groove in the water storing pipe.

The invention provides a solid hazardous waste pyrolysis method, which relates to the technical field of pyrolysis. The method realizes the pyrolysis of solid hazardous waste through solid hazardous waste pyrolysis equipment equipped with a base, a drive structure, a drive motor, a smoke exhaust pipe, and a cleaning structure. The present invention successfully solves the following technical problems: one is that most of the materials are easily concentrated at the bottom of the cylinder during the cracking process of the existing device, resulting in insufficient heating of the material; It is easy to remain inside the cylinder; moreover, during the pumping process, hard objects are likely to cause deformation of the filter screen, and the floating residue after cracking is easy to block the filter screen.
