Technical Field

[0001] The invention relates to the technical field of cutting, in particular to a cutter. Background Art

[0002] At present, manual pliers are usually used to cut the cable cores or insulator pins of microwave components. The quality of the pliers, visual accuracy, and operation skills determine the quality of the cutting. The difficulty of manual operation varies for wire cores or pins with different length requirements. Since manual cutting has large errors that lead to scrapping of materials, there are certain limitations and uncontrollability; manual operation of cable cores or insulator pins is currently a common method.

[0003] Since there are many types of cable cores or insulators used in microwave components, most of them are produced in small batches, and it is extremely difficult to process the lead pins to a length of about 1mm or 0.5mm, and the cut surface is uneven. At present, the utilization rate of cable cores or insulator lead pins cut by manual pliers is low, and repeated processing increases costs and production cycles. Summary of the invention

[0004] In view of the shortcomings of the above-mentioned existing production technology, the applicant provides a cutter that is easy to operate, can cut wires of different sizes, and can keep the cutting length consistent, with high cutting efficiency.

[0005] The technical solution adopted by the present invention is as follows: a cutter comprises a lower pressure plate, a base and a knife holder, one end of the lower pressure plate is hingedly connected to the base, the other end of the lower pressure plate is cantilevered, one end of the knife holder is hingedly connected to the base, the other end of the knife holder is fixed with a blade, and the other end of the knife holder is elastically supported on the base by a spring, a limit block is fixed on the side surface of the lower pressure plate facing the base, a plurality of strip holes for inserting and placing the wire body are provided on the plate surface of the lower pressure plate, when the wire body is inserted into the strip hole, the wire body is arranged between the limit block and the blade of the blade, when the lower pressure plate is pressed toward the direction of the base, the knife holder is pressed and rotated until the blade of the blade abuts against the limit block and cuts the wire body.

The tool holder is in the shape of a plate, and one end of the tool holder is hinged between two opposite side walls of the mounting groove. The length direction of the hinge axis at the hinge at one end of the tool holder is parallel to the length direction of the blade. In the process of pressing the lower pressure plate in the direction of the base, the blade is moved against the plate surface of the lower pressure plate until the blade is against the limit block.

[0008] The length direction of the strip-shaped hole is perpendicular to the length direction of the blade, and the strip-shaped hole extends from the position of the limiting block to the direction of the blade.

[0009] A strip-shaped through hole is provided at the bottom of the mounting groove, a guide column is fixed to the bottom surface of the other end of the tool holder, a spring sleeve is arranged on the outside of the guide column, one end of the spring rests on the tool holder, and the other end of the spring rests on the inner bottom surface of the mounting groove, the end of the guide column is inserted in the through hole, and the length direction of the through hole is perpendicular to the length direction of the hinge axis at the hinge at one end of the tool holder.

[0010] A groove is provided on the other side of the lower pressing plate, and strip holes are provided at the bottom of the groove. There are more than two strip holes which are arranged in parallel and at intervals, and the arrangement direction of the strip holes is parallel to the length direction of the blade.

[0012] The beneficial effects of the present invention are as follows: the present application can set up multiple strip holes, each with a different width, so as to cut wires of different diameters, and has a wide applicability. The thickness of the lower pressure plate is constant, so when inserting the wire, the thickness of the lower pressure plate can be used as a reference to keep the cutting length of the wire consistent. The entire structure is relatively simple and easy to operate, and multiple wires can be cut at the same time, so that the cutting efficiency is higher. BRIEF DESCRIPTION OF THE DRAWINGS

A plurality of strip holes 11 for inserting and placing the wire body 70 are provided on the surface of the lower pressing plate 10. When the wire body 70 is inserted into the strip holes 11, the wire body 70 is arranged between the limit block 60 and the blade 41 of the blade 40. When the lower pressing plate 10 is pressed toward the direction of the base 20, the knife holder 30 is pressed and rotated until the blade 41 of the blade 40 abuts against the limit block 60 and cuts the wire body 70. The present application can be applied widely by setting a plurality of strip holes 11, each of which has a different width, so as to cut wires 70 of different diameters. The thickness of the lower pressing plate 10 is constant, so when inserting the wire 70, the thickness of the lower pressing plate 10 can be used as a reference to keep the cutting length of the wire 70 consistent. The whole structure is relatively simple and easy to operate, and a plurality of wires 70 can be cut at the same time, so that the cutting efficiency is high.

[0019] The base 20 is in the shape of a plate, and a mounting groove 21 is provided on one side of the plate surface of the base 20 facing the lower pressure plate 10. The tool holder 30 is in the shape of a plate, and one end of the tool holder 30 is hinged between two opposite side walls of the mounting groove 21. The length direction of the hinge axis at the hinge at one end of the tool holder 30 is parallel to the length direction of the blade 41. In the process of pressing the lower pressure plate 10 in the direction of the base 20, the blade 41 is moved against the plate surface of the lower pressure plate 10 until the blade 41 abuts against the limit block 60.

[0020] The length direction of the strip hole 11 is perpendicular to the length direction of the blade 41 , and the strip hole 11 extends from the position of the limit block 60 to the direction of the blade 40 .

[0021] The bottom of the installation groove 21 is provided with a strip through hole 22, the bottom surface of the other end of the tool holder 30 is fixed with a guide column 80, the spring 50 is sleeved on the outside of the guide column 80, one end of the spring 50 is against the tool holder 30, and the other end of the spring 50 is against the bottom surface of the inner groove of the installation groove 21, the end of the guide column 80 is inserted in the through hole 22, and the length direction of the through hole 22 is perpendicular to the length direction of the hinge axis at the hinge of one end of the tool holder 30. During the rotation of the tool holder 30, the end of the guide column 80 moves in the through hole 22.

[0022] A groove 12 is formed on the other side of the lower pressing plate 10 , and strip holes 11 are formed at the bottom of the groove 12 . There are more than two strip holes 11 arranged in parallel and spaced apart. The arrangement direction of the strip holes 11 is parallel to the length direction of the blade 41 .

[0023] The middle of the tool holder 30 is hollow and plate-shaped, and a limit rod 90 is fixed between two opposite side walls of the mounting groove 21. The limit rod 90 is parallel to the length direction of the hinge axis at the hinged part of one end of the tool holder 30, and the limit rod 90 passes through the middle hollow of the tool holder 30. The limit rod 90 is used to control the rotation range of the tool holder 30.

[0024] The wire body 70 of the present application can be a cable core or an insulator pin, etc. During specific cutting, taking cutting the cable core as an example, the cutting process is as follows: the cable core is inserted into the strip hole 11, the outer insulating sleeve of the cable rests on the bottom of the groove 12, and the side of the cable core overhanging outside the strip hole 11 rests on the limit block 60. Since the thickness of the lower pressure plate 10 at the bottom of the groove 12 is constant, the length of the cable core inserted into the strip hole 11 is constant, so the cutting length is constant, the lower pressure plate 10 is pressed in the direction of the base 20, the lower pressure plate 10 presses the tool holder 30, the tool holder 30 rotates, the spring 50 is compressed, the blade 41 rests on the plate surface of the lower pressure plate 10 and moves until the blade 41 rests on the limit block 60, and the blade 41 cuts the cable core.
