The utility model discloses a brush with a rotatable brush head, which comprises a brush handle, and one end of the brush handle is connected with the brush head. Bristles are arranged on the upper side or the lower side of the brush head, a rotating shaft is arranged on the brush head, a connecting base is arranged at one end of the brush handle and provided with a rotating hole used for containing the rotating shaft, and the brush head can rotate around the rotating shaft, so that the angle of the brush head is adjusted to adapt to cleaning faces of different positions of shoes. A movable connecting structure and an elastic clamping assembly are arranged between the brush head and the connecting seat; the movable connecting structure is used for enabling the rotating shaft to rotate and not to be separated from the rotating hole; the elastic clamping assembly can lock the brush head after the brush head rotates to a use angle; when the brush head is subjected to external force larger than the external force driving the brush head to rotate, it is ensured that the brush head is locked after rotating, and the brush head can stably wash shoes.

The utility model relates to a kind of PC end voiceprint recognition interactive devices, including interactive panel, recognizer and dust protection part, the recognizer is installed on the surface of interactive panel, two connecting seats are rotatably installed in interactive panel side, hole part is equipped on the surface of connecting seat, it can be connected by bolt with PC end surface, 3M glue can also be installed in connecting seat side and installed on PC end surface, when not using, interactive panel is rotated, interactive panel back is leaned on PC end side, it does not occupy redundant space, when using interactive panel, horizontal pull buckle ring on the surface of guard plate, rotate interactive panel, it is convenient for face recognition probe to identify face, by pulling down guard plate, guard plate moves down and drives slider to extrude spring, voiceprint recognizer leaks, use, after use is completed, the press of buckle ring is loosened, under the spring rebound effect, guard plate shields protection to recognizer, and the guide rail of guard plate two sides is respectively located in two guide grooves and slides, limit guard plate only vertical movement.

This utility model relates to the field of mixer technology, and in particular to a mixer that facilitates sampling and testing. This device has a sampling device at the bottom of one side of the mixing tank. Pulling the handle outwards draws some liquid and particles from the bottom of the mixing tank into the sampling device. Continuing to pull the handle causes the second moving block and the second sealing ring to block the inlet of the sampling device, preventing excessive material from flowing out. Continuing to pull the handle moves the sample to the sampling hole, where it flows into the sampling cup at the bottom, completing the sampling. This device only requires pulling the handle to complete the sampling; the operation is simple and without complicated steps. After sampling, the sampling cup can be removed by moving it outwards. The sampling cup has a filter screen inside that intercepts particles, allowing operators to determine whether there is particulate matter sedimentation in the mixing tank and the severity of the sedimentation by observing the number of particles in the filter screen.
