Description

M267043 、 Instruction of Creation (1) [Technical Field to which the New Type belongs] This creation is about a utility knife with a C device at the front end of the utility knife holder. The main device has a sleeve type that can be inserted through the blade. f knife device, the center of rotation of the knife device is further provided with a tooth set portion which falls in the viewing hole relative to the knife line, so that the toilet can be easily obtained, so that the blade segment of the blade is cut so that it can be turned The knife is used to remove the coaxial rotation relationship, which replaces the conventional utility knife ^ and achieves the blunt blade segment to assist in breaking the blade edge segment, or the dream part and the knife part of the knife ^ Way, which can make the breaking operation faster and safer [Previous technology] Wen Wang # ° 1 π Art: It is a portable convenience worker commonly used for cutting work, and because it has multiple segments on the same blade When the blunt phenomenon occurs after using eight mouths, the user can get another sharp blade for re-operation after a period of 3 to 5 minutes of removal: the use of the knife has long replaced the traditional one. Cutting tools such as blades. As far as the current commercial Wu Gongdao is concerned, it mainly has a knife shell for a knife seat, and the edge of the knife # of the knife seat is provided with a continuous zigzag positioning groove to match the rear end of the blade. The position of the blade can be obtained by pushing the control, and the blades are designed as a breakable multi-section blade structure, so that the user can remove the blunt blade section to continue the sharp and sharp use of the utility knife. In the implementation of the blade breaking operation, it is usually carried out by a folding knife holder or an additional folding knife tool attached to the rear end of the knife case. In practice, the user must disassemble the folding knife holder from the rear end of the knife case. Hold the folding knife holder in one hand, and hold the M267043 creation instruction (2). Use a knife and grind the front end of the blade to force the folding knife holder. The second slot is broken into the slot of the folding knife holder, and it is completed. The blade J Ϊ two pieces of sharpened blunt edge segments are newly installed back to the rear end of the knife shell from the cutting line, and the T operation can be performed. Finally, the folding knife weight of the knife holder is changed to the blade = utility knife, and if other Extra previously. For the breaking operation, its implementation mode is almost the same as the above-mentioned 'known breaking operation', which requires the use of other folding knives and working knives to sharpen the blunt edge segments on their blades. The blade is connected to the tail end of the MF Xing Fruit Knife or used as an additional accessory pin: Guan Duo is additionally set at the cost of the folding knife with the costly removal of the tail end of the Meiwei knife; After returning to the positioning, the knives and knives have to return to their positions. After the completion of this kind of private work, the simplicity of the broken operation must be reduced. The consistency of the half and ^ knives is 'to be solved by themselves'. Therefore, the knife-like tool is set in the knife function, and i # h2 is not considered. Zhou Yan's consideration, * must be more laborious in one hand, and the Mang industry model 'not only wants to break the knife wound and form it: use it! It is easy to cut his hand with a blade. Solver.

M267043 Creation Instructions (3) In view of the lack of profitability of existing utility knives in blades and hidden safety concerns, the creators in the industry are 'ubiquitous based on their years of experience in related industries. The blade rapid breaking device, that is, the main literary art, further developed the original blade at the front end of the knife holder without affecting the utility knife ^ The purpose is to provide a sharpening device at the front end of the utility knife blade. Direct and fast completion of sharp and blunt continuous turning and turning = attached knife cutter Another purpose of this creation is to use the pure blade segment to quickly remove 'and sharpen the blade during the operation without accidentally being cut by the blade In addition to injury, the hands used on the palate need no contact. In addition, it can improve the safety of its operation. ": 之 # § is designed through the structure of the structure, so that j: The blade CL? The relationship of the centerline makes it easy to turn the knife. Ί It is easy to remove the blade segment and achieve a more labor-saving blade breaking operation implementer. Another purpose of the original creation is to make the guillotine cry through the structural design. In the unused state, it can be fixed, and it will not be loose and it will change the function of the knife. Weixiu In order to achieve the purpose of the previous disclosure, this creation is on the structural design, mainly provided with a knife folding device at the front of the knife holder of the art f The upper and lower extensions of the knife seat are a pair of pivots, and a pair of shaft holes are provided on the two pivot arms relative to the knife seat, so that a rotary cutter can be set, and the lower side of the front end of the utility knife shell A holder is set to restrict the rotation of the knife folding device, and the knife folding device has a sleeve part through which the blade teeth can pass, and a viewing hole M267043 is provided in the knife sleeve.

Fourth, the creation description (4), this viewing hole is located at the uppermost cutting edge section and the line is moved to the knife folding device. The fold line falls on the knife folding device to achieve the utility knife with minimal force. [Implementation method ] For the achievement of this creative effect, please refer to the first to the first. It is mainly provided with an embedded groove (1 1 (2 0) and a fixed utility knife blade with continuous teeth (3 polyline ( 3 1), and then push the control (blade (30) protrusion (34) and sipe) (and maintain the blade (30) cost of creating a utility knife and give the artist a description of the blade (30) When the center line of the knife seat (20) and the lower shaft part is blunt, only the position of the viewing hole of the blade part, that is, the center line of rotation, is used to quickly break the blunt blade blade. The composition and technical drawings are exemplified by the knife shell (1 0), the knife) of this creation, which is not shown in Figure 5 to obtain an inset knife holder (slot (21), and a slot (2 2). , At the knife 0), the blade (30 blades (30) divided into) is provided with a blade through 3 4) at the rear end, using the The basic function structure of the positioning slot (2) and the tool holder (20) of the knife holder (20) or the retracted 2 1) is controlled; Blade secondary—The cutting of the blade segment allows the blade segment to be intercepted when turning the turning knife, the front blade segment is broken and broken, the implementation method and the steps are described in detail below: Utility knife in the structural design shell (1 0 ) The opening is set 2〇), and the knife seat groove (2 1) can be provided in the lower edge groove (2 1)) is provided with a plurality of diagonally cut sections (3 2) holes (3 3). The piece (3 4) has to be moved back, and can push the control 2) Get the card position, enter the relationship type, and based on this construct, this creation is based on the front arm (2 3) (
