A geological survey sampler with an angle adjustment bracket
ActiveCN115306995Breduce crackingguaranteed fixed effectWithdrawing sample devicesStands/trestlesGeological surveyStructural engineering
The present invention provides a geological survey sampler with an angle adjustment bracket, comprising a sampler body, wherein the sampler body comprises a driving device and a drill bit, and the driving device and the drill bit are transmission-mounted, and the bottom of the driving device is located on both sides of the drill bit mounting position and is rotatably mounted with two sets of lifting handles through a rotating shaft. Compared with the prior art, the vertical accuracy of the drill bit drilling can be effectively improved, and compared with rough manual estimation, the accuracy is higher, and the soil sampling is more accurate. By reducing the impact of the drill bit's shaking on the surrounding environment and the squeezing effect on the ground around the borehole, the phenomenon of ground cracking around the borehole is reduced, and the surrounding environment is protected. It is simpler and more labor-saving to pull out the device later, and the ground will not be damaged. It has strong adaptability to the ground in different environments, can be adjusted and fixed on the ground according to the ground conditions, and the stability of the bottom of the device is enhanced.

A rotating toothbrush head and an electric toothbrush
This utility model discloses a rotary toothbrush head and an electric toothbrush, including a drive unit, a brush head, and a housing. The brush head is located on the side of the top of the housing, and the drive unit is located inside the housing and connected to the brush head. The drive unit moves linearly to drive the brush head to rotate. The drive unit includes a connector, a drive rod, and a first elastic member. One end of the first elastic member abuts against the connector, and the other end abuts against the inside of the housing. The brush head includes a brush disc, and the brush disc has a connecting shaft at one end near the drive rod. Through the cooperation of the connector and the first elastic member, the connector maintains contact with the output part on the electric toothbrush handle under the elastic action of the first elastic member. At the same time, when the connector receives the thrust from the output part on the electric toothbrush handle, the elastic force superimposed by the first elastic member can increase the frequency of reciprocating movement of the connector and the force of each movement, allowing the brush disc to output a higher frequency of rotation and a more stable rotational torque.
