Technical Field
The utility model relates to the technical field of cutter equipment, in particular to a foldable portable cutter.
Background
Cutters, also known as cutting tools, are mainly used for cutting operations in life and work.
The common cutters mainly comprise folding cutters and non-folding cutters, and compared with the non-folding cutters, the folding cutters are convenient to carry and widely used because the volume of the folding cutters can be effectively reduced.
The common foldable knife in the market at present is formed by movably connecting a knife handle and a knife body together in a pin joint mode, has a simple structure and lacks a locking mechanism for locking the knife body at an opening position and a closing position when the knife body is opened. Therefore, when the cutter is used in the process of opening the cutter body, if the back of the cutter body is subjected to larger external force, the cutter can automatically fold under the action of the external force, and accidents can occur to a user.

The utility model is realized by the following technical scheme: the foldable portable cutter is characterized by comprising a connecting rod, wherein fixing sheets are respectively arranged at the front side and the rear side of the upper end of the connecting rod, a containing cavity is formed between the two fixing sheets, a blade is arranged in the containing cavity, a positioning hole is formed in the blade, a through hole is formed in each fixing sheet, and a bolt penetrates through the through hole and the positioning hole to rotatably install the blade between the two fixing sheets;
the upper end of the fixing piece is also provided with a limiting column, and the limiting column is used for limiting the opening angle of the blade; the right side of the limiting column is provided with a spring type pressing column which is used for locking the blade.
Further, a limiting groove is formed in one side of the upper end of the blade, and when the blade is opened, the limiting column is clamped in the limiting groove; the other side is provided with a locking groove, and the spring type pressing column is clamped in the locking groove.
Further, the fixing pieces are fixed at the upper ends of the connecting rods through bolts, and reinforcing pieces are further arranged on the outer sides of the fixing pieces.
Further, the fixing piece and the reinforcing piece are provided with lightening holes.
Further, the lower part of the connecting rod is provided with threads, and nuts are arranged on the threads.
The beneficial effects of the utility model are as follows: the utility model has simple structure, can fix the device on any extension rod by using the connecting rod, and is convenient for personnel to use.
According to the utility model, the limiting columns and the spring type pressing columns are arranged to respectively limit the limiting grooves and the locking grooves on the blades, so that the blades in the cutter are safer to open and close.

Detailed Description
In order to make the objects, technical solutions and advantageous effects of the present utility model more apparent, the technical solutions of the present utility model will be further described below with reference to examples.
As shown in fig. 1 to 7, a foldable portable cutter comprises a connecting rod 1, wherein fixing sheets 2 are respectively arranged on the front side and the rear side of the upper end of the connecting rod 1, the fixing sheets 2 are fixed at the upper end of the connecting rod 1 through bolts, a reinforcing sheet 4 is further arranged on the outer side of each fixing sheet 2, a containing cavity is formed between the two fixing sheets 2, a blade 5 is arranged in the containing cavity, a positioning hole is formed in the blade 5, through holes 3 are formed in each fixing sheet 2, through holes 3 are also formed in the reinforcing sheet 4, and the bolts penetrate through the through holes 3 and the positioning holes to rotatably install the blade 5 between the two fixing sheets 2.
The upper end of the fixing piece 2 is also provided with a limiting column 6, and the limiting column 6 is used for limiting the opening angle of the blade 5; the spacing post 6 right side is equipped with spring type and presses post 7, and the lower extreme of spring type presses post 7 runs through stationary blade 2 to through spring coupling reinforcement piece 4, the upper end of spring type presses post 7 is equipped with spacing card, presses stationary blade 2 and reinforcement piece 4 of opposite side to press the upper end of post 7, and spacing card setting is used for preventing pressing post 7 from falling from holding the intracavity in stationary blade 2 inboard, and spring type presses post 7's effect to be used for locking blade 5.
