3results about How to "Quick installation replacement" patented technology

This utility model belongs to the field of medical devices, specifically a microneedle device for hair transplantation suitable for different scalp types. Addressing the problems of existing devices using fixed-size needles or inconvenient needle replacement, it is difficult to fully meet the needs of different scalp types. Especially when treating sensitive scalps, needles that are too thick or too thin can cause unnecessary damage or discomfort. The proposed solution includes a main body comprising a needle tube and a hollow needle, the hollow needle being fitted onto the bottom end of the outer wall of the needle tube; and a pushing component for pushing hair follicles, the pushing component being disposed inside the needle tube and the hollow needle, the pushing component including a push rod. The hollow needle is installed through a connecting component, allowing for quick replacement of hollow needles of different sizes to adjust patient sensitivity when adapting to different scalp types. The device is simple to operate and securely fixed, preventing detachment.

The utility model relates to traditional chinese medicinal material processing coarse screen technical field discloses a kind of coarse screen equipment used in traditional chinese medicinal material processing process, including bottom frame and base, the top end of the bottom frame is fixedly connected with connecting frame, the top end of the connecting frame is clamped with dust frame, the top end of the dust frame is fixedly connected with feed inlet, the top end of the feed inlet is clamped with top cover. The coarse screen equipment used in traditional chinese medicinal material processing process is provided with connecting frame and other parts, the top end of dust frame is fixedly connected with feed inlet, the top end of feed inlet is clamped with top cover, the top end of top cover is fixedly connected with third handle, top cover is detachably connected in the top of feed inlet, third handle opens top cover, traditional chinese medicinal material can be placed in sieve frame through feed inlet, then top cover is covered, so that dust is not easy to enter inside during screening, solve the problem that there is no shielding structure in top during screening, dust, impurities in air easily enter inside.

This utility model relates to the field of lithium industry technology and discloses a synthesis reactor for alkyl lithium production, including a reactor body, a discharge port, a feed port, and a motor. The discharge port and feed port are fixedly connected to the surface of the reactor body, and the motor is mounted on the surface of the reactor body. A clamping structure is provided on the surface of the reactor body, including a connecting rod. One end of the connecting rod is fixedly connected to the surface of the reactor body, and the other end is fixedly connected to a connecting plate. A groove is formed on the surface of the connecting plate, and a slider and a bidirectional screw are slidably connected to the inner wall of the groove. This utility model solves the problem that in existing alkyl lithium production synthesis reactors, the discharge port connection often presents difficulties in quick clamping, which over time affects the normal use of the equipment and consequently its operational stability.
