This utility model relates to the field of door lock technology, specifically a positioning and rotating handle device. It includes a mounting plate with a positioning ring installed in the center. A handle component is rotatably connected to the outside of the positioning ring. The handle component includes a rotating part, the front end of which is fitted onto the positioning ring. A spring is installed inside the rotating part, and a steel ball is attached to the end of the spring. The positioning ring has several equally spaced positioning grooves arranged in a ring on the side near the handle component. When the handle component rotates, the steel ball engages with each positioning groove in sequence, increasing rotational stability and feel. In this positioning and rotating handle device, the spring pushes the steel ball to engage with the positioning grooves on the positioning ring, achieving precise positioning of the handle component during rotation. Each rotation, with the steel ball embedding into the positioning groove, provides clear tactile feedback to the user, preventing any play or jamming during operation.

This invention discloses a laser cladding device for wear-resistant layers on plastic wire drawing machine screws, comprising a slide table, a robotic arm assembly fixedly connected to the top of the slide table, a welding head fixedly connected to the top of the robotic arm assembly, bases respectively provided on both sides of the slide table, and a turntable three rotatably connected to the top of the base. The turntable three has several annularly distributed grooves. This invention, through a point-contact clamping mechanism, can switch the surface contact clamping of the pressure plate to the point-contact clamping of the pressure block when cladding the end of the screw. By precisely adjusting the position of the pressure block, it avoids the already clad wear-resistant layer area and only contacts and fixes with the non-processed surface of the screw substrate. This ensures rotational stability during single-end processing and completely avoids damage such as squeezing cracks and peeling caused by the clamping mechanism to the incompletely cured wear-resistant layer, realizing continuous cladding of the entire surface of the screw from the main body to the end.

The present invention provides a stirring structure and a stirring method for low-vibration, highly efficient homogenization. It addresses the uneven force exerted on the stirrer by glass flowing into the mixing tank from one side, which impairs the long-term stable operation of the stirrer. Furthermore, the glass melt flowing in from one side tends to exhibit viscosity-temperature segregation proximally, reducing the homogenizing effect. By employing a specially shaped buffer basin to transfer the force of the liquid before it enters the mixing tank, and by continuously injecting glass melt into the mixing tank using a 360° overflow process, the rotational stability of the entire stirrer is significantly improved. This ensures a long service life, reliability, and efficient homogenization of large flow rates.It enables a uniform force to be applied to the stirrer in the circumferential direction of the glass melt, significantly improves the problem of abnormal vibrations of the stirrer during operation, and achieves efficient homogenization even with large flow rates of glass melt, thus providing device support for the production of high-flow substrate glass.
