The invention discloses a multifunctional bone screw applied to a bone with a poor sclerotin condition. The multifunctional bone screw applied to the bone with the poor sclerotin condition consists of an outer screw and a self-locking expanding bar, wherein the outer screw is a whole body formed by a screw body and a base, the interior of the screw body is a cylindrical hollow part, the tip part of the screw body is provided with a gap cut along the longitudinal axis of the screw body, circular gradient type interface reinforcing holes are symmetrically formed in the gap along the thread pitch of an outer thread at intervals and are communicated with the cylindrical hollow part, and the apertures of the gradient type interface reinforcing holes from the tip part of the screw body to the back part of the screw body are sequentially reduced; the self-locking expanding bar is a cylinder body, the diameter of the cylinder body is slightly smaller than the inner diameter of the cylindrical hollow part of the interior of the screw body, the front end of the self-locking expanding bar is conical, an inwards V-shaped groove is arranged at the conical back part of the self-locking expanding bar, the self-locking expanding bar is wedged with the cylindrical hollow part of the interior of the screw body after being embedded in the cylindrical hollow part of the screw body. The multifunctional bone screw applied to the bone with the poor sclerotin condition, which is disclosed by the invention, simultaneously expands the screw body and realizes self locking, and can realize stable fixation operation effect under a poor sclerotin operation condition.

The invention discloses a high-stability fabricated wallboard for interior decoration, and belongs to the technical field of wallboards. The wallboard comprises two first wallboards and a second wallboard; the two first wallboards are mutually attached together; the two first wallboards are fixedly connected through two tightening mechanisms; the two tightening mechanisms are symmetrically arranged up and down; the second wallboard is hinged to one side faces of the first wallboards; and a positioning mechanism is arranged in the second wallboard. According to the high-stability fabricated wallboard for interior decoration, by arranging the tightening mechanisms and a mounting mechanism, the two first wallboards are pulled to be away from each other, a certain gap exists between the two first wallboards at the moment, and a sliding rail block drives a fastening block to be tightly clamped in a fastening groove, so that the situation that the fixing effect of the first wallboards is affected due to loosening and disengaging of a sliding sleeve is avoided, and the fastening block can be controlled to be disengaged from the fastening groove; the sliding sleeve, check blocks and otherstructures are disassembled, so that parts are stored, and the cost is saved; and meanwhile, the two first wallboards can be disassembled, so that storage, installation and transportation are convenient.

The invention relates to a support sleeve, in particular to a simple arm support sleeve. By aiming at solving the technical problems, the invention provides the simple arm support sleeve with the effects that the arms of a patient can be conveniently fixed; the arms cannot be moved, so that the secondary injury is avoided. The invention has the technical implementation scheme that the simple arm support sleeve comprises arc-shaped plates, a moving block, a casing, a push plate, binding belts, a rubber connecting plate, a base and the like, wherein the left and right side surfaces of the rubberconnecting plate are fixedly connected with the arc-shaped plates; the left part of the front side of the outer side surface of the left side arc-shaped plate and the right part of the front side ofthe outer side surface of the right side arc-shaped plate are symmetrically provided with two guide slide grooves; a guide slide block is arranged in the guide slide groove at the upper part. The simple arm support sleeve has the advantages that the injured arms are put into the arc-shaped plates; then the arms are fixed through the binding belts; more convenience is realized; the support effect is better; through a regulating device, the angle of the arc-shaped plate can be regulated to the angle suitable for the arms of the patient; therefore the arm swinging can be avoided; the patient armplacement can be more comfortable.

The invention discloses an inserting disk with a pull assisting device. The inserting disk with the pull assisting device comprises the pull assisting device (20), an inserting-disk face plate (30), a printed circuit board (50) and a connecting shaft (10), wherein the connecting shaft (10) is in a stepped shape, and a mounting hole (501) of the printed circuit board (50) is in a special-shaped hole structure which is capable of preventing rotation of the connecting shaft (10). The pull assisting device (20) comprises a head portion (201) and a handle (203), a stepped shape is formed between the head portion (201) and the handle (203), and a boss (202) is arranged at the transition position of the handle (203) and the head portion (201). A notch (303) is arranged at one end of the junction position of a bottom plate portion (302) and a face plate portion (301) of the inserting-disk face plate (30), and the handle (203) of the pull assisting device (20) penetrates through the notch (303) and is located outside the inserting-disk face plate (30). By means of the inserting disk with the pull assisting device, the pull assisting device, the printed circuit board and the inserting-disk face plate can be well assembled with high reliability, and cost is low.
