The invention relates to the technical field of engraving, in particular to a device for artistic engraving. The device for artistic engraving comprises a cutter handle and a tool bit; a threaded rodis fixed to the tool bit; a threaded groove is formed in the end portion of the cutter handle, and the threaded rod is connected in the threaded groove in a threaded manner; a scrap removing pipe is further included; the cutter handle is internally provided with a wind cavity in which a fan is arranged; the lower portion of the wind cavity is provided with an air outflow hole, and the lower cavitywall of the wind cavity is rotationally connected with a rotating disk; the rotating disk is provided with air blowing holes; one end of the scrap removing pipe is fixed to the rotating disk, and theother end of the scrap removing pipe is provided with rotating blades and a grinding disk; the grinding disk is rotationally connected to the scrap removing pipe; the rotating blades are fixed to thegrinding disk; protruding blades are fixed to the end portion of the threaded rod in the circumferential direction; an air feeding pipe is further arranged in the cutter handle; and one end of the air feeding pipe communicates with the wind cavity, and the other end of the air feeding pipe is used for blowing air to the protruding blades. Due to the scheme, the problems that in the prior art, anengraving cutter cannot grind the side wall of an engraving gap after engraving, scraps in the engraving gap cannot be blown out in time, and the tool bit is prone to get loose in the engraving process are solved.

The invention provides winding machining equipment used for manufacturing a high-pressure rubber hose. The equipment completes work through cooperation of a bottom plate, a bottom framework, a lockingdevice, a winding drum set, a clearance pulling device and a folding connecting plate. The winding machining equipment provided by the invention can be used for solving the problems that a steel wireis generally wound on a winding drum, during winding, the steel wire is pulled out, accordingly, the winding drum is driven to rotate, the steel wire unwinding speed may be faster than the winding speed due to an excessive high rotating speed in the winding drum rotating process, consequentially, the steel wire is in a relaxed state in the conveying process, thus, the steel wire fails to be woundtightly on the outer wall of an inner rubber hose, the overall degree of density is decreased, the steel wire wound on the inner rubber hose is usually wound in multiple layers, an existing winding method is usually single-layer winding, a multi-layer winding effect can be achieved through multiple times of circulative winding, and the work efficiency is low.

A pressure-type self-expanding anti-loosening grounding pile for construction, which relates to the field of construction technology, and includes a cone. Both sides of the top of the cone are fixedly connected with movable rods, and the top of the movable rod is fixedly connected with spring one and spring one. The top of the cone is fixedly connected with a pile body that is movably connected with the outer side of the movable rod, the middle part of the top of the cone is fixedly connected with a guide column that is movably connected with the bottom of the pile body, the outer side of the top of the guide column is fixedly connected with a limit block, and the middle part of the pile body The movable connection has the rotating block which is connected with the guiding column. The pressure-type self-expanding anti-loosening grounding pile for construction is used in conjunction with the movable block and the anti-loosening plate. When the modified grounding pile is driven into the ground, the movable block will expand outward, and the anti-loosening plate will be under the action of the movable block. Squeeze and unfold to the outside, the anti-loosening plate and the ground can be effectively squeezed to prevent the movement of the ground pile, thereby achieving the effect of anti-loosening, effectively improving the stability of the ground pile, and improving the service life of the building.

The invention relates to a bolt looseness preventing device which comprises a connected piece, a bolt and a looseness preventing compacting device. The bolt looseness preventing device is characterized in that the connected piece is fixedly connected by the bolt, and the extending part of the bolt is fixedly connected with the looseness preventing compacting device; the looseness preventing compacting device is composed of a limiting ring, a shell and a compacting panel, and the limiting ring is sleeved on the outer side of the shell; one side of the shell is fixedly connected with the compacting panel through a compression spring; a first groove is formed in the circumferential direction of the shell, and a first semi-cylindrical baffle body is arranged in the first groove; and a second groove is formed in the inner wall of the limiting ring, and a second semi-cylindrical baffle body is arranged in the second groove. The compacting panel is compacted on the surface of a nut, and the nut can drive the looseness preventing compacting device to loosen together; but, at the moment, the planes of the first semi-cylindrical baffle body and the second semi-cylindrical baffle body contacts with each other, and a looseness preventing connecting long shaft and a looseness preventing connecting short shaft are fixed, so that the nut cannot loosen.

The invention provides a high-pressure rubber hose manufacturing and winding process. The operation is completed by the cooperation of the bottom plate, the bottom frame, the anti-loosening device, the winding drum group, the gap traction device and the folding connecting plate. When placed on the reel, the steel wire will be pulled out when winding, which will drive the reel to rotate. During the rotation of the reel, the pay-off speed may be faster than the winding speed due to the high speed of the reel, resulting in a slack state of the steel wire during transportation. The steel wire cannot be tightly wound on the outer wall of the inner rubber hose, and the overall compactness is reduced. The steel wire wound on the inner rubber hose is usually wound in multiple layers. The existing winding method is usually single-layer winding, and is wound through multiple cycles. In order to achieve the effect of multi-layer winding, the work efficiency is low and other problems.
