This application provides a fully automatic tightening mechanism for the inner tie rod of an automotive steering gear, including a bottom linear module. A middle rotating feeding module is located on the upper side of the bottom linear module, and an upper clamping and tightening module is also located on the upper side of the bottom linear module. The bottom linear module includes a first base plate, a first slide rail slider, a servo motor, a fixed side of the lead screw support seat, a supporting side of the lead screw support seat, a ball screw, and a moving plate. Two slide rails are formed on the upper surface of the first base plate. This application utilizes the clamping and tightening module, employing a cylinder propulsion structure primarily responsible for propulsion during the tightening process. The clamping mechanism effectively clamps the inner tie rod, and the servo tightening mechanism, driven by a servo tightening machine, achieves tightening of the inner tie rod. This mechanism offers higher automation, better tightening effect, higher efficiency, and greater savings in labor costs.

The utility model relates to the technical field of vegetable basin faucets, and provides an anti-shaking vegetable basin faucet capable of enhancing the installation stability of the vegetable basin faucet between a bedplate, which comprises a faucet body, a water outlet pipe rotationally arranged on the faucet body, and a threaded pipe fixedly arranged at the lower end of the faucet body, the device is characterized in that an upper gland and a lower gland are detachably arranged on the threaded pipe, inner threaded channels are formed in the middle of the upper gland and the middle of the lower gland respectively, arc-shaped mounting pieces are longitudinally and fixedly arranged on the lower surface of the upper gland, and a deformation opening which does not affect outward expansion and deformation of the lower ends of the arc-shaped mounting pieces is formed between the arc-shaped mounting pieces. The height of the arc-shaped installation piece is not larger than the thickness of an external installation panel, a rubber piece is arranged between the inner wall of the arc-shaped installation piece and the threaded pipe, an upper end shell of the rubber piece is detachably and fixedly arranged at the upper end of the arc-shaped installation piece, and the transverse length of the rubber piece is smaller than the arc length of the arc-shaped installation piece.

This invention belongs to the field of surgical instrument technology and discloses a disposable sterile specimen retrieval bag with spill prevention, comprising a cannula, a push rod, and a specimen bag. The push rod is slidably connected inside the cannula, and the specimen bag is connected to one end of the push rod. The specimen bag includes a support strap with several ratchet teeth on one side. One end of the support strap is connected to a buckle, and the buckle has protrusions that match the ratchet teeth. The other end of the support strap passes through the buckle. The support strap and the buckle form an elastic annular support ring. A hollow sleeve is fitted onto the annular support ring, with one end connected to the end of the support strap and the other end connected to the buckle. The hollow sleeve is connected to the retrieval bag body. This invention solves the technical problems of existing specimen bags having limited options for aperture specifications, being easily damaged, and having a semi-closed opening that hinders the smooth placement of specimens.

This application relates to a mobile phone securing cord structure and clothing, belonging to the field of clothing accessories technology. It includes: a cover plate, located in the pocket of the clothing and used to cover the pocket opening; and a securing cord, sewn in a wavy shape to the underside or edge of the cover plate, having multiple hook parts for flexible connection to a mobile phone case. This application connects the securing cord to the mobile phone case, allowing the phone to be placed directly in the pocket. This effectively connects the phone to the clothing body, whether during outdoor activities or when taking the phone out for use, effectively preventing the risk of the phone accidentally falling off or being lost. It is particularly suitable for use during strenuous outdoor activities and when using the phone at heights, preventing the phone from falling and improving the safety of carrying the phone while wearing clothing.

The application discloses a waistband structure, and belongs to the technical field of waistbands, which comprises a main band body and a sub-band body, the two ends of the main band body and the sub-band body are respectively and respectively detachably connected, the sub-band body is arranged near the middle position of the main band body and is used for gathering the main band body, and at least one adjusting part is formed by folding the main band body relative to the sub-band body, and a connecting piece for fixing the adjusting part is arranged on the outer wall of the main band body. The adjusting part is folded to make the main band body capable of being flexibly adjusted according to the body shape of a user, effectively avoiding that the top of the main band body presses or clamps the lower edge of the chest of the user, or that the bottom of the main band body rubs against the hip bone or the hip of the user to cause discomfort, and improving the size adaptability and ergonomics compatibility. The adjusting part can be fixedly installed on the outer wall of the main band body through the connecting piece, thereby preventing the adjusting part from being randomly rolled up and raised to cause discomfort to the user, and improving the wearing comfort of the user.

The voice navigator comprises a main shell, side shells inclining inwards are arranged on the left side and the right side of the main shell, a cavity is formed in the inner side of the main shell, and a bottom plate is fixedly connected to the cavity; a storage battery, a control chip, a Bluetooth communication module and a satellite positioning module are arranged on the bottom plate, a forward laser radar distance measuring sensor is arranged at the bottom of the front side of the main shell, a lateral laser radar distance measuring sensor is arranged at the bottom of the front side of the inclined side shell, and a radio device is arranged at the top of the main shell. The front side of the side housing is also provided with a sound box, a control chip, a Bluetooth communication module, a satellite positioning module, a network communication module, a forward laser radar distance measuring sensor, and a lateral laser radar distance measuring sensor. The system is comprehensive in detection range, inconvenient to wear, easy to operate and the like.

This invention discloses a maintenance device for a low-voltage power distribution network system, belonging to the field of maintenance equipment technology. It includes a height fine-tuning mechanism, a bolt tightening mechanism, a rolling guide mechanism, and a limiting mechanism. During actual operation, the height fine-tuning mechanism allows for precise alignment, facilitating the accurate removal of bolts and angle steel. The bolt tightening mechanism automatically tightens bolts and is adaptable to slight angle tilts during tightening. The rolling guide mechanism facilitates lifting angle steel to a suitable position on the utility pole or removing angle steel from the pole for complete replacement, improving maintenance efficiency. The limiting mechanism limits the angle steel and bolts, facilitating disassembly or installation / replacement.
