Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of cutting tools, in particular to an adjustable width positioning structure of a cutting tool. BACKGROUND
[0002] In modern manufacturing and handicraft industry, cutting tools are indispensable important equipment, widely used in cutting operations of wood, metal, plastic and other materials. In order to meet the cutting needs of different sizes and shapes, cutting tools need to have high flexibility and adjustability.
[0003] Referring to Figure 1 , the traditional positioning plate 5a on the traditional cutting tool is fixed on the extension table 4a, which can move up and down around the circumference, and the extension table 4a is installed on the drag bar 3a, which remains stationary. By moving the extension table 4a horizontally on the drag bar 3a, the traditional positioning plate 5a is driven to obtain the desired workpiece width positioning.
[0004] However, the problem is that, referring to Figures 2-3 , when the cutting tool is used to position and cut the width of the workpiece 9a, the shortest width positioning distance is limited by the width of the workbench 2a, and the longest width positioning distance is limited by the length of the drag bar 3a. Considering the structure of the machine, cost and other factors, the length of the workbench 2a and the drag bar 3a is limited and cannot be too long or too short, resulting in that when the required width positioning of the workpiece 9a is too long or too short, the existing width positioning structure cannot meet the requirements.
[0005] The above content is only used to assist in understanding the technical solutions of the present application, and does not mean that the above content is the closest prior art to the present application. SUMMARY

[0007] The technical solution adopted by the present application to solve its technical problems is: an adjustable width positioning structure of a cutting tool, comprising: a cutting tool body, a workbench is formed on the cutting tool body, drag bars are arranged on both sides of the workbench, and an extension table slides on the drag bars; a width positioning mechanism is installed on the extension table, comprising a width positioning rod, a first width positioning plate and a second width positioning plate, the first width positioning plate rotates on the outside of the extension table, the width positioning rod horizontally penetrates the first width positioning plate and can slide on the first width positioning plate, and the second width positioning plate slides on the end of the width positioning rod outside; wherein the positions of the width positioning rod, the first width positioning plate and the second width positioning plate can be locked by a locking mechanism; by adjusting the positions of the width positioning mechanisms on both sides and the extension platform, the cutting needs of different widths can be met.
[0008] In some embodiments, the drag bar is a U-shaped rod object, including sliding parts at both ends and a limiting part in the middle section, and the two sliding parts are kept horizontal.
[0009] In some embodiments, the extension table top slides on both sliding parts at the same time.
[0010] In some embodiments, the extension table top is formed with a containing space for the rotation of the first width positioning plate.
[0011] In some embodiments, the extension table top is kept horizontal, and the top of the extension table top is flush with the top of the workbench top.
[0012] In some embodiments, the locking mechanism includes a first bolt and a second bolt, the first bolt is threadedly connected with the first width positioning plate, and the second bolt is threadedly connected with the second width positioning plate.
[0013] In some embodiments, the first bolt and the second bolt are tightened to tightly abut against the width positioning rod to lock the first width positioning plate and the second width positioning plate, and vice versa.
[0014] In some embodiments, the containing space is formed with a limiting hole matching the diameter of the width positioning rod.
[0015] The beneficial effects of the present application are that the width positioning mechanism composed of the first width positioning plate, the second width positioning plate, and the width positioning rod replaces the original traditional positioning plate. When the width positioning required for cutting does not exceed the extension table top, the first width positioning plate is turned up to lift, the width positioning distance is controlled by moving the width positioning rod left and right, and the width positioning rod is fixed by tightening the first bolt to lock the positioning distance.
[0016] When the width positioning required for cutting exceeds the extension table top, the width positioning rod is slid outward to a position that does not interfere with the rotation of the first width positioning plate and does not deviate from the first width positioning plate, the first width positioning plate is then turned down and placed in the containing space, and then the first width positioning rod is slid into the limiting hole, the width positioning rod is fixed by tightening the first bolt, the width positioning distance is controlled by moving the second width positioning plate left and right, and the second width positioning plate is finally fixed by tightening the second bolt to lock the positioning distance, effectively extending the adjustable width positioning length. The width positioning structure proposed in the present application can meet the positioning requirements when the workpiece width positioning is too long or too short. BRIEF DESCRIPTION OF DRAWINGS

[0027] Some preferred / modified embodiments based on the above embodiments will be further described below. The following embodiments can be selected or combined.
[0028] As shown in the figure, Figure 4 The trailing rod 3 is a U-shaped rod-shaped object, comprising sliding portions 301 at both ends and a limiting portion 302 in the middle, and the two sliding portions 301 are kept horizontal.
[0029] Further, the extension platform 4 simultaneously slides on the two sliding portions 301, which can ensure that the extension platform 4 stably and horizontally slides on the trailing rod 3, the limiting portion 302 limits the maximum sliding amount of the extension platform, and the upper surface of the extension platform 4 is flush with the upper surface of the workbench surface 2.
