This utility model relates to the field of power supply device technology and discloses a power cord anti-pull fixing device, including a cable and a rectangular cover. The cable passes through a circular hole. A limiting component is provided inside the rectangular cover cavity, including a first clamping unit and a second clamping unit. A fixing unit is provided between the first clamping unit and the rectangular cover cavity. A compression unit is provided between the second clamping unit and the rectangular cover cavity. By setting up components such as an arc segment, a first hanging plate, a second hanging plate, a tension spring, a second crossbar, a slide, a guide rod, and a compression spring, the arc segment deformation provides initial buffering, the tension spring stretches to generate a reverse elastic force to disperse the pulling force, and the second crossbar slides along the slide to compress the compression spring to form secondary buffering. The guide rod ensures stable movement direction and avoids deviation from the force. The double elastic buffering structure significantly improves the anti-pull protection effect of the cable and effectively reduces the risk of the cable being pulled apart.

This utility model discloses a constant temperature shaking incubator for drug development, relating to the technical field of drug development equipment. It includes a chamber and a shaking mechanism. A culture concave tray is mounted on the upper end of the shaking mechanism. Multiple sets of guide blocks are parallelly installed inside the culture concave tray. Multiple sets of sliding seats are slidably installed on the outer wall of each set of guide blocks. Multiple sets of fixing mechanisms are provided inside the culture concave tray. This utility model, by setting up fixing mechanisms, can fix culture containers of different specifications with the cooperation of a semi-circular seat, a semi-circular clamping plate, a connecting plate, a connecting rod, a supporting spring, and a circular plate, without the need to replace parts, improving the equipment's versatility. Furthermore, under the action of the supporting spring, it can provide a continuous and uniform clamping force. The silicone anti-slip pad increases the coefficient of friction, so even under high-frequency shaking, the container has no risk of sliding or tipping, effectively avoiding sample leakage.

This invention discloses a structure with dual-end limiting function, specifically relating to the field of shower head technology. It includes a mounting base with a freely rotatable and anti-detachment rotating sleeve at its bottom. The rotating sleeve has a threaded hole, with a limiting block and a limiting component at each end of the hole. The limiting component includes a sealing plate and a second limiting block that tilts inward towards the threaded spiral structure. A screw is threaded into the threaded hole, with an extension at the top of the screw. A support body rotatably mounted within the mounting base can be linked with the extension via an eccentric shaft-roller, cylindrical spiral rail-pulley, or rack-gear structure. This invention prevents the screw from detaching and avoids axial failure through a dual-limiting structure. The rotating sleeve and screw work together to raise and lower the extension, enabling flexible adjustment of the shower head tilt angle. The rotating sleeve is equipped with ball bearings and anti-slip textures, and the screw, with its special dimensions and thread count design, also features a sliding retainer. This solves the problems of inconvenient adjustment, jamming, and lack of effective limiting in traditional shower head support bases, resulting in smooth adjustment, precise positioning, and safe use.
