The utility model belongs to the lawn laying technical field especially is a kind of modular splicing simulation lawn laying device, including draw bar, still including the partition piece of setting in draw bar side, layering board, glueing board, material pipe, material pump, storage bottle, tow frame, tow bar and counterweight roller, the one end of draw bar and fixed installation in the partition piece rotation connection of layering board surface, and the layering board and the glueing board constitute integrated structure, and the surface of glueing board still with one end of material pipe fixed connection, the work of the layering board and glueing board of this device can be carried out gluing work when the size and position adjustment work of lawn are completed, can greatly reduce the tediousness of laying work, and then can effectively improve the work efficiency of laying, and under the action of counterweight roller still can be compacted to the position of gluing, can make the connection structure more closely.

This utility model discloses a top-mounted, adjustable-speed rotary pencil sharpener, including a support cover, a pencil holder on the support cover, a support gear below the support cover, and a pair of support shafts inside the support cover. A start switch and a PCB circuit board are connected to the pencil holder on one side. The PCB circuit board is connected to the motor circuit, and the motor is connected to the support gear via a gear set. A blade holder is located below the support gear, and an adjustment component for adjusting the pencil tip thickness is located below the blade holder. The pencil tip thickness is controlled by the up-and-down movement of the adjustment rod via a seesaw structure. When the pencil tip reaches the top of the adjustment rod, the PCB circuit board controls the motor to reverse and retract the pencil. The closer distance between the motor and the blade assembly results in less motor power loss, a more compact connection structure with less mechanical friction noise, more stable motor speed, and a more stable center of gravity. The bottom shavings box design allows for a larger shavings capacity and easier cleaning.

This application discloses a quick-connect respirator and breathing device. The quick-connect respirator includes a body and a connecting device, one of which serves as a first component and the other as a second component. The first component has a mounting groove with a pre-positioning area and a locking area that are interconnected. The locking area has a mating groove that opens towards the pre-positioning area. The second component has a pivot. The portion of the second component with the pivot enters the locking area via the pre-positioning area, and the pivot correspondingly enters the mating groove. A locking member is also movably mounted on the first component. The locking member has a first position that prevents the pivot from entering the pre-positioning area and a second position that opens the pre-positioning area. In the first position, the locking member holds the pivot within the mating groove. The technical solution of this application can achieve quick connection or disconnection while ensuring stable connection, improving user experience and adaptability, and increasing production efficiency. The connection structure is simple and compact, facilitating production and assembly.

The utility model discloses a multilayer nesting type spiral inductance coil relates to inductance coil field, including coil body, connecting subassembly and fixed seat, the center of coil body is provided with the fixed rod, and the outer side of fixed rod both ends is provided with blocking ring, and the end portion of fixed rod is provided with the clamping rod, and the fixed rod is provided with the clamping rod. And the outer walls of the two ends of the clamping rod are fixedly connected with limiting rings. According to the multi-layer nested spiral inductance coil, by arranging the connecting assembly and the moving assembly, in the using process of the spiral inductance coil, a worker can conveniently install the spiral inductance coil, the connecting structure is compact, and the situation that the structure is loosened in the subsequent using process is avoided; the spiral inductance coil can be used smoothly, meanwhile, a worker can adjust the supporting structure according to the actual situation of the spiral inductance coil conveniently, the spiral inductance coil is installed more conveniently, and the worker can use the spiral inductance coil conveniently.
