The utility model discloses a kind of thyroid ablation post-neck ice compress band, including front cloth band, the middle part of front cloth band is equipped with rectangular through-hole, heat conduction layer is sewn in the inside of through-hole, the left side of front cloth band is sewn and has the storage assembly for placing ice bag, the both ends of front cloth band are sewn and have connecting band;The utility model connects first fixed band and second fixed band by connecting band at the both ends of the front cloth band with hollow, make overall form scarf style around patient neck, not only guarantee the reliability of ice compress, but also suitable for different population use, while setting heat conduction layer and storage assembly in the middle part of front cloth band, storage bag in storage assembly is divided into two areas by separation cloth for placing ice bag, so that it corresponds with heat conduction layer, heat conduction layer can efficiently transfer the temperature of ice bag to improve ice compress effect.

This application discloses a pair of pliers that is easy to assemble and disassemble, including a left and a right pair of pliers arranged in a cross configuration. The left pliers have a left plier shaft portion, and the right pliers have a right plier shaft portion. The left plier shaft portion includes a left connecting seat with a connecting groove. A connecting sleeve with internal threads is concentrically arranged in the connecting groove. The right plier shaft portion includes a right connecting seat with a gasket mounting groove and a connecting sleeve on opposite sides. A connecting hole is formed at the bottom of the gasket mounting groove. During assembly, the connecting sleeve is inserted into the annular mounting groove outside the connecting sleeve, and the bolt passes through the gasket and the connecting hole and is screwed into the internal thread of the connecting sleeve. Therefore, the pliers provided by this application can be assembled and disassembled using only a screwdriver. Its double-sleeve structure allows for both sliding rotation and adjustment of tightness at any time by tightening the bolt. The two pliers can be separated by removing the bolt, making it convenient to clean the dirt inside the pliers. The assembly and maintenance are simple, and the gasket forms an end face seal to prevent lubricating oil from seeping out, thus avoiding dirty hands and clothes.

The utility model provides a novel throttle valve belongs to valve body technical field, including valve subassembly and anti loosening structure, valve subassembly is by valve body, installation cover, valve rod and valve core is composed, the utility model: valve rod is by upper stem body and lower stem body two parts constitute, is connected with screw rod in the upper stem body bottom, lower stem body top installs the sliding sleeve, and screw rod is connected in the thread groove of sliding sleeve inside opening in the thread, and the inside of installation cover is installed with the guide sleeve, and the inner wall of guide sleeve opens the limit slot, and sliding sleeve slides in the limit slot through both sides' limit sliding block, when the upper stem body rotates, drives screw rod to rotate in the sliding sleeve, and sliding sleeve is lifted and removed along screw rod under the limit of limit slot, thereby makes the drive valve core lift and open and close, because the upper stem body and lower stem body are connected through screw rod sliding sleeve, make valve rod not to produce loosening when being vibrated, avoid the leakage caused by the valve core upward movement.
