The utility model relates to the field of agaric production equipment, and discloses an agaric production impurity removal screening device which comprises a bearing frame, a screening frame is arranged at the upper end in the bearing frame, a screen assembly is arranged in the screening frame, and the screen assembly comprises sliding grooves formed in the inner walls of the two sides of the screening frame. A screen frame slides in the sliding groove, and the inner wall of the screen frame is fixedly connected with a steel wire screen. According to the edible fungus screening device, the steel wire screen with the appropriate hole diameter is rotated according to the quality and size of edible fungi, then the screen frame slides into the sliding groove, the clamping columns are pressed during sliding, and after the screen frame is completely placed into the sliding groove, the screen frame is clamped into the holes of the screening frame through the clamping columns, so that the screen frame is fixed; and therefore, the steel wire screens with different hole diameters can be quickly mounted and replaced, and the screening device can effectively screen and remove impurities from agaric with different qualities and sizes.

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 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.

The utility model relates to the technical field of fire-fighting equipment, in particular to a mounting and fixing device of a fire-fighting intelligent alarm, which comprises a mounting bottom plate, a connecting column arranged in the middle of the mounting bottom plate, two guide cylinders arranged in the connecting column at intervals, and insulating slide blocks arranged in the guide cylinders. A pressure spring is arranged between the insulating sliding block and the bottom of the guide cylinder, a conductive rod is fixed on the insulating sliding block, a columnar hollow structure of a connecting sleeve is matched and inserted with the connecting column, an alarm body is fixed at the end part of the connecting sleeve, a power supply input end is arranged at the end part of the alarm body, and the power supply input end is matched and butted with the conductive rod; and the positioning pin is used for limiting the separation between the connecting sleeve and the connecting column. According to the installing and fixing device of the fire-fighting intelligent alarm, the alarm body is fixed to the connecting sleeve, rapid installation and replacement are achieved through rapid butt joint between the connecting sleeve and the connecting column, meanwhile, rapid connection of a power source can be achieved, and replacement efficiency is improved.

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.

This utility model discloses a plugging installation device, relating to the field of plugging heads, which solves the technical problem that existing plugging methods easily lead to misalignment of the plug, causing leakage. The device includes a plugging head, comprising a plug head, a limiting part, and a fixing member. The plug head has a plugging component at one end, and the other end of the plug head is connected to one end of the limiting part. The fixing member is connected to the other end of the limiting part, and a fixing protrusion is provided at the end of the fixing member away from the limiting part. A clamp assembly includes a fixing part and a limiting member. A limiting hole is formed on the outer wall of the fixing part, and the limiting member is disposed within the limiting hole to abut against the fixing protrusion, thereby restricting the movement of the fixing member. An installation member connects the clamp assembly and is used to push the plugging head to insert the plugging component on the plug head into the workpiece plugging hole. This achieves automatic insertion of the plugging component into the process hole, rapid installation and replacement of the plugging component, and ensures the installation depth.
