This invention discloses an excavator and its chassis in the field of excavator base plate technology, aiming to solve the problem of huge slewing resistance of the upper part when traveling on a slope in the prior art. It includes: when the road slope direction is nearly coincident with the uphill / downhill direction, the pitch cylinder extends and retracts to drive the slewing bearing mounting platform and base to pitch around the intermediate frame, reducing the angle between the slewing bearing shaft axis and the gravity direction of the upper part in one degree of freedom, thereby adjusting the slewing bearing shaft axis to nearly coincide with the gravity direction of the upper part; when a component of the road slope direction is nearly coincident with the uphill / downhill direction, and another component direction points to the left and right sides, at least two pitch cylinders extend and retract unequally to drive the slewing bearing mounting platform to tilt around the base to the left and right sides, reducing the angle between the slewing bearing shaft axis and the gravity direction of the upper part in two degrees of freedom, thereby adjusting the slewing bearing shaft axis to nearly coincide with the gravity direction of the upper part.

This invention relates to the field of rock and soil exploration technology, and discloses a rock and soil drilling exploration device for engineering construction. The device includes a main body with a support frame rotatably connected inside. A drill rod is mounted on the side wall of the support frame. When two arc-shaped plates form a cross shape around the outer surface of the drill rod, the invention enhances the rotational force of the motor, causing the motor to drive the drill rod to rotate and disengage from a jammed state via a threaded shaft. After disengagement, the hydraulic rod retracts to its output end. As the hydraulic rod retracts, it resets the two arc-shaped plates, allowing them to fit onto the outer surface of the drill rod, enabling normal operation. This reduces the likelihood of the drill rod jamming when encountering harder rock layers during rotation within the rock and soil strata, thus improving the exploration quality of the device.

This application relates to a passivation device, which includes a passivation tank, a frame, and a drum. A limiting post is provided on the drum, and a slider slides up and down on the limiting post. A stirring rod is hinged to the slider, and a stirring rod is hinged to the limiting post. An elastic element is provided on the limiting post, and a positioning component is provided on the stirring rod. After a workpiece is placed into the receiving tank, the slider is moved so that the hinged portions of the stirring rods extend away from the limiting post. When the drum rotates, the extended portions of the stirring rods agitate the workpiece in the receiving tank, thereby separating the adhered workpieces and improving the passivation effect. When the drum is not in use, the positioning state of the slider is released. Under the action of the elastic element, the slider moves the hinged portions of the stirring rods closer to the limiting post, reducing the risk of damage to the stirring rods due to impact when the workpiece is poured in.

The application discloses a plastic button quick plug connector, which comprises a socket pipe, a plug pipe and a button, limit ring grooves, mounting grooves and mounting ring grooves are formed on the inner wall of the socket pipe from top to bottom, the mounting grooves are three groups or more and are distributed at equal intervals in the radial direction, a single group of the mounting grooves comprises two symmetrically arranged clamping grooves, a single clamping groove occupies 120 degrees in the circumferential direction, the cross section of the clamping groove is in the shape of a trapezoid, the groove bottom is wide and the groove mouth is narrow, barbs are formed at the groove mouth of the clamping groove, elastic friction blocks are embedded in the clamping groove, and the friction blocks partially extend out of the clamping groove; the limit ring grooves are provided with two or more sealing rings; a plug-in part with a tapered outer wall is formed at the end of the button, a step is formed at the top of the plug-in part, the button is inserted into the plug pipe in the radial direction, the button moves up and down within the range of the limit ring grooves, and a plurality of groups of annular through holes are formed on the plug-in part in the radial direction.

The utility model discloses a medical plastic sagittal saw handpiece, and relates to the technical field of medical plastic instruments. The medical plastic sagittal saw comprises a cutter body, a handle body and a transmission structure, wherein the cutter body comprises a blade part and a cutter handle part which are connected with each other; the front end of the handle body is used for being connected with the knife handle part, and the rear end of the handle body is used for being connected with an external rotation driving device.
