The application provides a continuous pushable blood sampling pen, and relates to the technical field of blood sampling pens. The blood sampling pen comprises a key structure, a transmission unit, a needle withdrawing structure and a depth adjusting assembly. The needle withdrawing structure is connected with the transmission unit, and the relative position relationship between the depth adjusting assembly and the transmission unit in a first direction has a first state and a second state. The first direction is a circumferential direction around a first axis. When the depth adjusting assembly and the transmission unit are in the first state, the pushing force of the key structure in the first direction acts on the transmission unit to push the blood sampling needle in the blood sampling needle fixing assembly in the direction of the first axis. When the depth adjusting assembly and the transmission unit are in the second state, the pushing force of the key structure in the first direction is prevented from acting on the transmission unit, so as to avoid the blood sampling needle in the blood sampling needle fixing assembly from being pushed out. The convenience of operation when the needle is withdrawn is ensured, and the problem of blood sampling needle failure caused by accidental operation of an operator during blood sampling is prevented.

This invention discloses an integrated automated production line equipment for inserting and unloading PCBs, comprising an inserting and unloading machine, a first inserting flybar, a second inserting flybar, and an inserting and unloading machine aligned with the inserting and unloading machine, arranged sequentially from the board infeed conveyor to the board return conveyor. The inserting and unloading machine has a first station and a second station, both arranged along a first direction. The inserts are conveyed to the first station for docking and then transferred to the second station to complete the PCB insertion and unloading operation. The first inserting flybar docks with the inserting and unloading machine to convey the inserts to the main line; the second inserting flybar transports the inserts from the main line to the inserting and unloading machine. This design achieves automated PCB insertion and unloading operations, realizing a fully automated electroplating process. Simultaneously, it features a stable structure, minimal human intervention, reduced labor costs, and no damage to the PCBs, resulting in high production efficiency.

The utility model relates to the technical field of demonstration devices, and discloses an angle-adjustable exhibition hall demonstration device, which comprises a display screen. The supporting disc is arranged at the bottom of the display screen; the supporting cylinder is arranged at the top of the supporting disc; the lifting assembly is arranged in the supporting cylinder and controls the display screen to ascend and descend; the first adjusting assembly is arranged above the supporting disc and used for adjusting the vertical angle of the display screen; the second adjusting assembly is arranged in the supporting disc and used for adjusting the transverse angle of the display screen; a second motor is fixedly connected to the inner wall of the bottom end of the supporting cylinder. The vertical angle of the display screen is adjusted through the first adjusting assembly, the transverse angle of the display screen is adjusted through the second adjusting assembly, the limitation that a traditional device can only be adjusted in the longitudinal direction is overcome, audiences can obtain a good viewing angle from different directions such as the side face or the inclined side, and the displayed content can be comprehensively and clearly viewed; and the visiting experience of the audience is greatly improved.

This utility model discloses a high-pressure microenvironment vapor deposition device, relating to the field of vapor deposition technology. It includes a fixed structure, with a sample structure mounted at the bottom of its inner cavity. The fixed structure includes a base, and a sealing cover is mounted at the bottom of the base. A sealing cover door is rotatably connected to one side of the outer wall of the sealing cover. Air inlets are provided on both sides of the outer wall of the sealing cover. Through the coordinated operation of a stepper motor, a transmission rod, and a rotating rod, the opening and closing of the sealing plug is precisely controlled, thereby controlling the opening and closing of the nozzle of the first spray tube and thus precisely controlling the thin film processing flow. Furthermore, a high-pressure automatic valve and specific structure in the second sealing tank can automatically open the nozzle to precisely coat the defective area upon detection of coating defects. Combined with real-time infrared thermal imaging monitoring, compared to traditional devices, this achieves intelligent and controllable operation of thin film processing, not only ensuring the quality of film coverage but also efficiently repairing defects and improving the overall processing effect.
