For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] like Figure 1 and Figure 2As shown, a vernier marking ruler comprises a ruler seat 3 and a marking ruler rail 2 with scale lines, the left side of the marking ruler rail 2 is a reference surface 4, the marking ruler rail 2 is vertically mounted on the reference surface 4 of the ruler seat 3, a movable ruler 6 is slidably mounted on the marking ruler rail 2, a marking needle 7 is mounted on the movable ruler 6, and a roller assembly 5 is vertically mounted on the reference surface 4. When the roller assembly 5 contacts the table surface of the workpiece 20, the marking needle 7 contacts the table surface of the workpiece 20. In this embodiment, the surroundings of the workpiece 20 are The processed flat surface can be fitted with the reference surface 4. Further, the workpiece 20 has at least two mutually perpendicular flat surfaces. Preferably, the workpiece 20 is a rectangular plate. When marking, the reference surface 4 is fitted with the side wall of the rectangular plate, and the roller assembly 5 is in contact with the table of the rectangular plate. At this time, the roller assembly 5 can play a supporting role. During the movement of the vernier marking ruler, the roller of the roller assembly 5 rolls along the table, thereby avoiding damage to the table of the workpiece 20. Figure 5 As shown, when marking, after the reference surface 4 is fitted with the side wall of the rectangular plate, the position of the movable ruler 6 on the marking ruler is adjusted, and then the spacing between the marking needle 7 and the reference surface 4 is adjusted. After the position of the marking needle 7 is adjusted, the vernier marking ruler is moved, and the reference surface 4 is moved to fit the flat surface of the workpiece 20, so that the marking needle 7 slides out a line on the table of the workpiece 20, and then the reference surface 4 of the vernier marking ruler is fitted with another flat surface, and then the marking needle 7 is adjusted to the specified position, the vernier marking ruler is moved, and finally another line is formed. The intersection of the two lines is the place where holes need to be punched. Therefore, the vernier marking ruler does not require a marking platform or an operator to carry the workpiece 20. It only needs to expose two mutually perpendicular flat surfaces of the workpiece 20, thereby improving the practicability of the vernier marking ruler, facilitating the operation of the marking operator, and improving the marking efficiency.

[0025] In this embodiment, if Figure 1 and Figure 2 As shown, the roller assembly 5 includes a roller, a shaft and a locking nut. A roller is rotatably mounted on one end of the shaft. The installation of the roller on the shaft belongs to the prior art and will not be described in detail. Moreover, the roller with the shaft can also be purchased commercially. The other end of the shaft is a screw that matches the thread of the locking nut. The shaft is installed on the reference surface 4 of the ruler seat 3, and the roller is located on the left side of the ruler seat 3, and the locking nut is located on the right side of the ruler seat 3. Furthermore, a second adjusting hole 12 is provided on the reference surface 4 of the ruler seat 3, and a step is provided on the shaft. The shaft is inserted into the second adjusting hole 12 and the locking nut is locked. During installation, the shaft is inserted into the second adjusting hole 12, and then the height position of the shaft is adjusted. When the position of the shaft is adjusted, the locking nut is locked. At this time, after the roller is placed on the table top of the workpiece 20, the marking needle 7 contacts the table top of the workpiece 20.

[0026] In this embodiment, if Figure 3 and Figure 4As shown, a liftable adjustment plate 9 is also installed on the movable ruler 6, and a roller assembly 5 is installed at the bottom of the adjustment plate 9. In the present embodiment, the vernier ruler is supported by two roller assemblies 5. When the heights of the two roller assemblies 5 are adjusted, the reference surface 4 fits with the flat surface. During the movement of the vernier ruler, it is only necessary to ensure that the reference surface 4 fits with the flat surface. By rolling the rollers on the surface of the workpiece 20, the vernier ruler is ensured to move in the same horizontal plane, thereby improving the convenience of marking.

[0027] In this embodiment, if Figure 3 and Figure 4 As shown, the movable ruler 6 is provided with a horizontal slide groove 61 that slidably cooperates with the marking ruler rail 2, so that the movable ruler 6 can move linearly relative to the marking ruler rail 2, and the movable ruler 6 is provided with a locking screw. When the movable ruler 6 moves to the specified position, the screw can be locked. The movable ruler 6 is provided with a screw for locking, which belongs to the prior art. The setting method of the movable ruler 6 and the ruler rail of the existing vernier caliper can be referred to; in this embodiment, a convex portion 62 is provided at the bottom of the movable ruler 6, and a vertical slide groove 64 is vertically provided on the convex portion 62. The adjustment plate 9 is slidably installed in the vertical slide groove 64, and a first adjustment hole 10 is provided on the adjustment plate 9. The first adjustment hole 10 is penetrated by a The fastening screw 11 is tightened, and one end of the fastening screw 11 passes through the first adjusting hole 10 and is threadedly connected to the protrusion 62. By adjusting the height of the adjusting plate 9, the height of the roller assembly 5 on the adjusting plate 9 can be adjusted. When adjusting, the fastening screw 11 is loosened, and the adjusting plate 9 can slide in the vertical slide groove 64. Since the adjusting plate 9 is slidably installed in the vertical slide groove 64, the straightness of the up and down movement of the adjusting plate 9 is guaranteed, thereby ensuring that the axis center line of the roller can be parallel to the table surface of the workpiece 20 after the reference plane 4 is fitted with the flat surface of the workpiece 20. When the position of the adjusting plate 9 is adjusted, the fastening screw 11 can be locked.

[0028] In this embodiment, if Figure 3 and Figure 4 As shown, a guide column 63 is vertically arranged at the bottom of the movable ruler 6, and a guide block 72 is arranged on the top of the marking needle 7. A guide hole is opened on the guide block 72. The guide column 63 is slidably fitted in the guide hole, and the guide block 72 and the guide column 63 are locked by a locking screw. The bottom of the marking needle 7 has a tip 71. By changing the relative position of the guide column 63 and the guide block 72, the position of the marking needle 7 can be adjusted, thereby ensuring that after the roller assembly 5 contacts the table surface of the workpiece 20, the marking needle 7 can contact the table surface of the workpiece 20.

[0029] In this embodiment, if Figure 1 and Figure 2As shown, a first handle 1 is horizontally installed on the right end face of the ruler base 3, and a second handle 8 is vertically installed on the front side face on the left side of the marking ruler rail 2. When in use, the operator holds the corresponding handles with both hands and applies a leftward thrust to the first handle 1, thereby ensuring that the reference surface 4 fits the flat surface of the workpiece 20. After applying a force in the forward and backward directions to the second handle 8, the vernier marking ruler can be moved forward and backward, thereby facilitating the vernier marking ruler to draw lines on the table surface of the workpiece 20.

[0030] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
