The utility model relates to the technical field of paper holders, in particular to a folding anti-skidding paper holder which comprises a holder bottom, a holder top and a connecting assembly, the holder top is arranged above the holder bottom, the connecting assembly is arranged between the holder top and the holder bottom, the connecting assembly comprises connecting pieces, a supporting hard plate and a swinging piece, the connecting pieces are distributed on the four edges of the top face of the holder bottom, and the supporting hard plate is connected with the swinging piece. The supporting hard plates are arranged at the two ends of the bottom face of the supporting top, clamping grooves are formed in the positions, close to the supporting hard plates, of the top face of the supporting bottom, the swing pieces are arranged on the two sides of the supporting top, a first reinforcing groove is formed in one end of the top face of each swing piece, one end of each swing piece is connected with an extension piece, and a second reinforcing groove is formed in the middle of each extension piece. When beverage packaging is carried out, after the supporting top and the supporting bottom are used in cooperation with the bottom of a cup, the swing piece and the extension piece can be turned over towards the cup cover, after turning over, the first reinforcing groove or the second reinforcing groove is buckled to the cup cover according to the size of the cup, and the paper support is prevented from being separated from the cup.

This utility model relates to the field of grinding machine fixture technology, specifically a mold grinding machine fixture, including a base body. A rotation limiting mechanism is provided at the upper end of the base body, and a clamping mechanism is provided at the upper end of the rotation limiting mechanism. The clamping mechanism includes a lower limiting slide plate. A left clamping plate is integrally formed on one side of the upper part of the lower limiting slide plate, and a right upright plate is integrally formed on the other side of the lower limiting slide plate. A threaded pressure rod is threadedly connected to the right upright plate, and one end of the threaded pressure rod is rotatably connected to the right clamping plate. The right clamping plate is slidably connected to the lower limiting slide plate, and a dust removal component is slidably connected to the inner side of the right clamping plate. This utility model, by designing a rotation limiting mechanism between the base body and the clamping mechanism, allows the workpiece fixed at its upper part to rotate 30° to adjust its position. Furthermore, the dust removal component in the clamping mechanism not only removes dust but also allows for easy removal and cleaning.

The utility model relates to the field of liquid crystal display screen equipment, and discloses a modularized splicing buckle type liquid crystal display screen which comprises an installation frame, a liquid crystal screen is detachably connected to the front surface of the installation frame, a buckle assembly is arranged on the rear surface of the installation frame, an auxiliary assembly is arranged on the bottom face of the installation frame, and the buckle assembly comprises a buckle plate. A mounting hole is formed in the rear surface of the mounting frame, fixing bolts are detachably connected to the upper end and the lower end of the buckle plate, a positioning groove is formed in the position, close to the lower side of the fixing bolts, of the front surface of the buckle plate, and a mounting groove is formed in the axis position of the right surface of the buckle plate. According to the utility model, the parts such as the buckle plate, the rolling ball, the telescopic rod and the like in the buckle assembly are matched with each other by utilizing the connection relationship, so that the smoothness in the embedding process of the equipment is improved, the mounting convenience of the buckle assembly is enhanced, the locking effect on the buckle assembly is realized, and the positioning effect of the equipment is enhanced.

The application discloses a kind of aluminium profile curtain wall protective window rail welding-free buckle device and installation method, it is related to building engineering technical field, including, fixed piece, fixed and worn in the curtain wall keel;Connecting female end, detachably set on the outside of the fixed piece;Connecting male end, set in the end of the rail, with the connecting female end plug-in cooperation, and form self-locking.The beneficial effects of the application are that the fixed piece is fixed on the curtain wall keel, the connecting female end is arranged on the fixed piece, and the connecting male end is arranged on the rail. When the connecting male end is inserted into the connecting female end, the locking effect is achieved, and the rail is fixed on the curtain wall keel. The effect of quick installation is achieved, which saves time and effort and improves work efficiency.

The utility model relates to food processing manufacturing field discloses a kind of processing and preparation device of instant bird's nest, including box, the bottom end of box lateral wall is provided with water injection pipe, the bottom end of box is provided with drain pipe, the outer wall of box is provided with door plate, the inner wall of fixed block is fixedly connected with guide block, the inner wall of guide block is slidably connected with T block.In the utility model, the preparation device is provided with a pull-out assembly. By pushing the door plate, the T block will extrude the inclined surface of the lever. When passing through the hole of the T block, the lever will be pushed by the spring, thereby completing the clamping of the T block and locking the position. When the heated bird's nest metal can needs to be taken out, pull the door plate and the push rod at the same time, cancel the limit, and the T block will clamp the second group of levers, thereby achieving the locking effect of the opening and closing state of the door plate.
