An ophthalmologic cutting device having a base support section for attachment with a movement generating device and a tip with a blade section. The blade section preferably has upper and lower edges, and a forward aspiration free edge extending between them, with the upper edge having a shorter longitudinal length compared with the lower edge and where the forward edge slopes down from a distal end of the upper edge to a distal end of the lower edge, and the lower edge presenting a material contact surface that is thinner in thickness than the upper edge. A slope back in the proximal direction of the forward edge of, for example, 10 to 45 degrees with a straight and/or curving forward edge or a combination of a straight and forward edge sections is preferred. Embodiments of the blade include a blade converging in thickness from top to bottom and one having a curved upper forward edge region and one with a lower edge that has a distal straight section and a recessed section positioned proximal of said distal straight section. The forward edge is also preferably defined by longitudinally diverging, opposing side walls.

A cutter includes a main body. The top edge of the main body is provided with a holding portion, and its two sides extend outward to form a pair of lugs. A pair of gaps is formed between the main body and the pair of lugs. The cutter further includes a cutting unit wrapped by the main body. The cutting unit has one side formed with a pointed end portion and another side formed with a cutter edge. The pointed end portion protrudes out of the holding portion, and the cutter edge is exposed out of the gaps. The multi-function cutter is able to cut and remove various packaging members easily and efficiently.

A cutter includes a main body and a cutting unit. The main body is lengthwise defined to have a dispensing section, a holding section and a storage section in sequence. The holding section is gradually contracted toward two ends and defined to be a stop portion, and the storage section is bored with a through hole. The cutting section has one side formed with a pointed end and another side provided with a cutting edge. The main body is integrally covered on the cutting unit, leaving the pointed end and the cutting edge exposed and letting the pointed end located at a central upper edge of the dispensing section. By so designing, the cutter of this invention can easily cut off and remove various kinds of packaging members, able to elevate efficiency of removing packaging members from a packing box and integral in functional design.

The invention discloses a sleeve workpiece continuous feeding mechanism, and belongs to the field of workpiece machining and conveying mechanical equipment. A pushing mechanism and a transfer mechanism of the invention are successively and horizontally fixed to the upper side of a loading base in the horizontal direction. A reciprocating guide plate is slidably disposed on the translation guide ofa translation bracket in the horizontal direction. A translational push plate in circular structure and matching a bearing cylinder material path is vertically fixed to the output end of a pushing cylinder. The two sides of the reciprocating guide plate and the tube material end of a translation support are provided with reset tension springs. The middle of the lower side of a transfer circular plate is fixed to the end of the upper side of a loading shaft. A plurality of bearing cylinder mechanisms are evenly arranged in order on the transfer circular plate along the radial direction of thetransfer circular plate. The sleeve workpiece continuous feeding mechanism is reasonable in structural design, can translate, push, and accurately place the sleeve workpieces one by one, transfers, loads and machines the sleeve workpieces smoothly and efficiently, achieves the degree of automation of the workpiece loading, and satisfies the needs of production and use.

The invention discloses a sliding slot type cutter device. The sliding slot type cutter device comprises a cutter head. The cutter head comprises a cutting edge and a cutter body. The cutting edge comprises a special-shaped cutting edge body. A guide groove is formed in the cutter body and comprises guide rolls clamped to a cutter. A manually operated type drive device is arranged on the cutter body and pushes the guide groove to move or slide. The cutting edge advances while sliding or rotating during cutting. The sliding slot type cutter device is simple in structure, time and labor are saved during operation, cutting is convenient and efficient, cost is low, cutting quality is good, the situation that cut ends or residual slag are/is left on cut objects is avoided, and the cutter head rotates clockwise to pull-cut and saw-cut the cut objects and rotates counterclockwise to cleave the cut objects.

The present invention relates to a vehicle trim bar, in particular a roof trim bar, for covering a channel, in particular a roof channel, in a vehicle structure having a trim bar profile which is formed with a fixing leg for fixing the vehicle trim bar within the channel to the vehicle structure and a support leg for supporting the vehicle trim bar on a channel bottom of the channel, the support leg being formed with a support web which projects from the trim bar profile in a manner extending along a longitudinal direction of the vehicle trim bar and which is manufactured from a plastic material. Furthermore, the invention relates to a fixing arrangement for a vehicle, in particular a motor vehicle, comprising such a vehicle trim bar.

The invention is a device and method that allows a user to easily and efficiently hand cut a mat and liner without the need to reposition the mat board. The notched features of the top frame and the different widths of the cutter guides set the parameters for the beginning and of each cut on a mat or a liner for a framed and double matted piece of artwork. Consequently these cuts may be made by a user with limited need for the degree of care which is commonly required in mat cutting using current technology.

The invention discloses a sleeper cutting tool bit which comprises a rotating shaft, as well as a first cutting body used for cutting an inclined plane of a sleeper, and a second cutting body used forcutting an arc-shaped surface of the sleeper; the first cutting body is arranged in the middle of the rotating shaft in a sleeving mode, and comprises a plurality of cutter sets; and the second cutting body comprises two ends arranged on the rotating shaft in a sleeving mode. After the structure is adopted, during cutting, the sleeper cutting tool bit is close to and is embedded into the profilesurface of the sleeper, the first cutting body is attached to the inclined plane of the profile surface, and the second cutting body is embedded and attached to the arc-shaped surfaces of the right and left sides of the inclined plane; and then, the rotating shaft is driven by a power unit to drive the first cutting body and the second cutting body to cut the profile surface of the sleeper. Compared with the prior art, the sleeper cutting tool bit has the beneficial effects that the sleeper cutting tool bit can be tightly attached to the profile surface of a sleeper, and the cutting precisionand the cutting quality are improved; and only one-time positioning is needed during machining, and the cutting process is more convenient and efficient.
