The application can actively and low-noise adjust the flow under different working conditions.

This invention discloses a multifunctional drilling box for statically determinate fluid channels. The multifunctional drilling box includes a base, a first rotating shaft, a second rotating shaft, an anchoring assembly, a drive component, and a transmission assembly. The first rotating shaft is rotatably mounted on the base and has a first through hole. The second rotating shaft fits within the first through hole and is movable along the length of the first rotating shaft, and has a second through hole. The anchoring assembly is slidably mounted on the base, passes through the second through hole, and is rotatably connected to the second rotating shaft. The anchoring assembly has multiple fluid channels, each communicating with the first through hole. The drive component is mounted on the base and is connected to the first rotating shaft via the transmission assembly to drive the first rotating shaft to rotate. This multifunctional drilling box for statically determinate fluid channels avoids rotational movement of the fluid channels relative to the surrounding environment during operation, making the fluid channels suitable for conveying easily reactive and easily volatile fluid media.

The utility model discloses a hand-push type grinding machine, and relates to the technical field of grinding machines. The bottom of the working box is provided with a moving assembly with a moving function, the top of the working box is provided with a movable box, the front side of the interior of the movable box is provided with an inner cavity, the interior of the inner cavity is fixedly connected with a servo motor, and the output end of the servo motor is fixedly connected with a first rotating shaft; a locking assembly is arranged at the output end of the first rotating shaft, and an inner grinding wheel is arranged on the front side of the locking assembly. The lifting assembly drives the movable box to move upwards or downwards till the outer grinding wheel on the front side of the movable box corresponds to the position of a product, the first rotating shaft drives the inner grinding wheel and the outer grinding wheel to rotate through the locking assembly to start to polish the product, and the connecting rod and the outer grinding wheel can be conveniently disassembled through the locking assembly; the connecting rod and the outer grinding wheel are easy to replace, and sweeps generated during grinding of the connecting rod and the outer grinding wheel are recycled through the collecting assembly.

The invention relates to a pedal assembly (1) for a vehicle, comprising at least one pedal unit (10) for triggering a vehicle function, which pedal unit comprises a modularly constructed pedal head (20), and at least one mechanically sprung base unit (30), the pedal head is connected with a housing cover (7) which can move along the height direction (z) of the pedal unit (10) with a small stroke and is used for receiving the actuating force of the foot of a driver. The base unit is arranged between the at least one pedal unit (10) and the body of the vehicle and fixes the at least one pedal unit (10) to the body of the vehicle, and provides an additional stroke (H) along the height direction (z) of the pedal unit (10) when the pedal unit (10) is actuated, and thereby changes the tactile feedback at the driver's foot.

The utility model relates to rubber fender suspension technical field, and disclose a kind of for connecting rubber fender's hanger, including backplate, the top of backplate left side is fixedly connected with adjusting box, and the top and bottom of adjusting box inner cavity are rotatably connected with screw rod between through bearing, the outer surface of screw rod is connected with rectangular plate with screw thread, the left side of rectangular plate is fixedly connected with driving plate, the left side of backplate and located the outside of adjusting box are slidably connected with concave suspension frame, the utility model is connected with rectangular plate, driving plate, concave suspension frame, mounting hole and rocking handle by setting backplate, adjusting box, screw rod, can be suspended installation to rubber fender, simultaneously, it is convenient to carry out vertical adjustment to its installation position, by setting limiting component, rocking handle can be conveniently self-locked, avoid self-rotation movement, influence installation height, by setting above structure, can have installation adjustment function, to satisfy the use demand of customer, avoid that there is limitation in installation use.

This invention relates to the field of cutting tool technology, specifically to a general-purpose alloy milling cutter disc with chip breaker grooves for roughing and finishing. It includes a milling cutter, a tool holder mounted on the top of the cutter, and multiple chip removal grooves arranged in a circular array on the bottom of the cutter. Chip breaker grooves are formed between the chip removal grooves. A tool holder is located on the top of the milling cutter, and two L-shaped seats are mounted on the left and right sides below the tool holder. Connecting seats are mounted on the top of the two L-shaped seats. Locking components are located on the front and rear sides of the tool holder for locking the tool holder. A limiting component is located in the middle of the vertical end of the L-shaped seats. This invention, by setting the locking components, allows the sidewalls of the tool holder to be pressed by the two pressing seats, and simultaneously, the top surface of the tool holder is pushed by a pressing rod, thus ensuring a firm connection of the tool holder within the tool holder. This invention, through its pushing design, ensures that the tool holder is subjected to pressure from all directions, improving the connection stability of the invention.
