[0037] In order to better understand the above technical solutions, the above technical solutions will be described in detail below with reference to the drawings in the specification and the specific embodiments.

[0038] Embodiment:

[0039] As shown in Figures 1-3 , the application discloses a hand saw with angle adjustment auxiliary line drawing, which separately adds an angle adjustment mechanism, which can be adjusted and locked through a knob, and the angle can be adjusted arbitrarily according to the working condition during measurement, thereby increasing the flexibility of use.

[0040] The specific structure of the application comprises:

[0041] A saw handle 1, which comprises a handle part, one side of which is provided with an assembly groove for inserting a subsequent saw blade, and then the saw blade is assembled by screwing a bolt, thereby realizing the assembly of the saw blade.

[0042] A saw blade 2, one end of which is connected with the saw handle 1.

[0043] In order to realize auxiliary line drawing, the application additionally adds an auxiliary line drawing unit 3, which is convenient for line drawing, and the specific structure is as follows: the auxiliary line drawing unit 3 is rotatably installed on the handle 1, and the auxiliary line drawing unit can rotate relative to the saw blade 2.

[0044] Meanwhile, the application also provides an angle scale 5, which is marked on the saw handle 1 or the saw blade 2, and the intersection of the extensions of each scale line of the angle scale 5 coincides with the rotation axis of the auxiliary line drawing unit 3; when the auxiliary line drawing unit 3 rotates, it cooperates with the angle scale 5, thereby obtaining the angle of rotation, and finally facilitating the line drawing operation of the user.

[0045] In an embodiment, as shown in Figure 1 , the plane formed by the rotation track of the auxiliary line drawing unit 3 is parallel to the surface of the saw blade 2, and the auxiliary line drawing unit 3 specifically rotates in a plane, which is convenient for the user to draw lines and limit angles.

[0046] The auxiliary line drawing unit 3 in the application can be various structures, which are mainly used for auxiliary angle indication, and then the user can draw lines according to the subsequent needs.

[0047] Among them, as shown in Figure 2 , the auxiliary line drawing unit 3 in the application comprises:

[0048] A vertical bar 301, which can rotate, specifically rotates through a subsequent fixing piece 302.

[0049] The fixing part 302 is connected with the saw blade 2 and the saw handle 1 after passing through the vertical strip 301. The fixing part 302 is a rotating button, and other fixing parts with the function of loosening and tightening can also be used to realize the loosening and tightening of the vertical strip 301. When the vertical strip 301 is loosened, the vertical strip 301 can rotate freely. After reaching the corresponding position, the fixing part 302 is locked to facilitate the user to draw a line. Meanwhile, the center of the fixing part 302 can be used as the rotating shaft of the vertical strip 301.

[0050] In an embodiment, the vertical strip 301 in the application is a transparent vertical strip. At this time, the vertical strip 301 is provided with a mark center line 304. When the vertical strip 301 rotates later, the vertical strip 301 can be adjusted so that the mark center line 304 is aligned with the scale line to obtain the required angle. Then the user draws a line according to the required angle to obtain the required product.

[0051] In another embodiment, the vertical strip 301 is provided with the hollow groove 4. When the auxiliary line drawing unit 3 rotates, part of the angle scale line 5 is located in the hollow groove 4. Meanwhile, the vertical strip 301 is provided with the mark center line 304 which is located at the non-hollow part of the vertical strip 301. Similarly, when used, the mark center line 304 is aligned with the scale line to obtain the required angle. Then the user draws a line according to the required angle to obtain the required product.

[0052] In another embodiment, in order to better install the vertical strip 301, the recess 303 is formed on the side of the saw handle 1 which faces the vertical strip 301. When the vertical strip 301 is at the starting end, the vertical strip is located inside the recess 303. Then the fixing part 302 is located at one end of the recess 303. In this way, the locking of the vertical strip 301 can be completed, and a stable rotating point of the vertical strip 301 is provided. Combined with the aforementioned angle scale line 5, the angle scale line 5 can also be used as the 0-degree starting point.

[0053] Specifically, the side of the vertical strip 301 which is away from the recess 303 is parallel to the mark center line 304. In this way, the mark center line 304 can be used as an auxiliary reference surface when drawing a line later to improve the convenience of the user drawing a line.

[0054] The vertical strip 301 is provided with the mark center line 304. The mark center line 304 is convenient for aligning with the angle scale line 5 later to provide the user with an accurate angle.

[0055] The diameter of the fixing part 302 is not greater than the width of the vertical strip 301. In this way, deviation can be prevented when drawing a line.

[0056] Specifically, the hollow groove 4 in the application is a plurality of, preferably two as shown in the figure.

[0057] Further explanation is provided regarding this application:

[0058] The angle scale line 5 of this application is marked on the saw handle 1 or saw blade 2. As long as the intersection point of the extension of each scale line of the angle scale line 5 coincides with the rotation axis of the auxiliary scribing unit 3, the subsequent marking center line 304 can coincide with the scale line, thereby obtaining the angle.

[0059] This application utilizes a fastener 302 that passes through the vertical bar 301, the saw blade 2, and the saw handle 1 to further clamp the saw blade and prevent it from shaking during cutting. If the vertical bar or the saw blade becomes loose, the knob can be tightened.

[0060] When the vertical bar 301 rotates, if the vertical bar 301 is a transparent part, it is possible to directly observe whether the center line 304 of the mark coincides with the scale line; if the vertical bar 301 has a hollow groove 4, the angle scale line 5 on the saw body can be seen through the hollow groove 4. At the same time, there are multiple hollow grooves, which, combined with the center line of the mark, can be aligned to find the corresponding angle.

[0061] In this application, the diameter of the fastener 302 does not exceed the width of the vertical bar 301 to prevent deviations when drawing lines. Secondly, while the fastener 302 serves a fastening function, its bottom can clamp the saw blade to prevent the saw blade from shaking during cutting. If the vertical bar or saw blade becomes loose, the fastener 302 can be tightened.

[0062] Workflow: such as Figure 3 As shown, first adjust the angle of the vertical bar, then place the edge of the object to be cut against the vertical bar, and draw a line using the horizontal line at the top of the saw blade as a ruler to obtain the required cutting line 6.

[0063] Numerous specific details are set forth in this specification. However, it will be understood that embodiments of this invention may be practiced without these specific details. In some instances, well-known methods, structures, and techniques have not been shown in detail so as not to obscure the understanding of this specification.
