[0023] The preferred embodiments of the present application will be described in detail below with reference to the drawings. Those skilled in the art will appreciate that these descriptions are only descriptive and exemplary and should not be construed as limiting the scope of protection of the present application.

[0024] First of all, it should be noted that the orientation terms such as top, bottom, upward, downward, etc. mentioned in this article are defined relative to the directions in each drawing. These orientations are relative concepts and will therefore change according to their positions and states. Therefore, these or other orientation terms should not be understood as restrictive.

[0025] In addition, it should also be pointed out that for any single technical feature described or implied in the embodiments of this article or any single technical feature shown or implied in the drawings, these technical features (or their equivalents) can continue to be combined to obtain other embodiments not directly mentioned in this article.

[0026] It should be noted that in different drawings, the same reference numerals represent the same or substantially the same components.

[0027] Figure 1 is a partial exploded view of an embodiment of the saw assembly of the present application. As shown, the saw assembly typically includes a body 100, a chain guide 130 mounted at one end of the body 100, and a support plate 140 mounted at one end of the body 100 and positioned adjacent to the chain guide 130.

[0028] The body 100 constitutes the main component of the saw assembly. For convenient gripping, one or more handles may be mounted on the body 100. In the illustrated embodiment, a first handle 110 and a second handle 120 are mounted on the body 100. A motor and corresponding transmission means may be mounted inside the body 100. In the illustrated embodiment, the first handle 110 is disposed above the body 100, and the second handle 120 is disposed in a different direction relative to the first handle 110 to provide different operation modes to the user. For example, in the illustrated embodiment, the first handle 110 and the second handle 120 are disposed substantially perpendicular to each other and spaced apart by a certain distance. The second handle 120 may be disposed at the side of the body 100 and closer to the chain guide 130 relative to the first handle 110. The chain guide 130 is used to drive the saw chain or chain to achieve the desired cutting operation. For the sake of clarity, the saw chain on the chain guide 130 is not shown. In one embodiment, the chain guide is configured to be removable. The chain guide 130 may have a length dimension along a first axis A (to be described in detail below) and a width dimension in a direction perpendicular to the first axis A. The chain guide 130 may be configured to be substantially axially symmetric and have a symmetry axis (not shown) extending along the first axis A.

[0029] The support plate 140 is positioned adjacent to the chain guide plate 130. In the illustrated embodiment, the support plate 140 is configured to be disposed substantially parallel to the chain guide plate 130. One or more bolt holes 143 may be provided on the support plate 140. Corresponding bolt holes 103 are provided at one end of the body 100. The support plate 140 can be fixed in place by bolts (not shown). In one embodiment, two bolt holes are provided on the support plate 140. In another embodiment, one or more than two bolt holes may be provided on the support plate 140. Typically, the side of the support plate 140 away from the body 100 is configured to have a flat surface.

[0030] The support plate 140 includes a plurality of portions, such as including a platform portion 141 and a ramp portion 142 located at the lower end of the platform portion 141. In one embodiment, a ramp portion 142 is also provided at the upper end of the platform portion 141. Both the platform portion 141 and the ramp portion 142 are configured to be substantially parallel to the chain guide plate 130. When installed in place, the support plate 140 protrudes from one side of the body 100, and the surface of the platform portion 141 is configured to be substantially parallel to one side of the body 100. Ramp portions 142 are respectively provided at both ends of the platform portion 141, and a smooth shape transition is provided from the platform portion 141 to the ramp portion 142. As shown in the figure, the length of the platform portion 141 may be greater than the width dimension of the saw assembly 130, such that Figure 1 when viewed in the lateral direction, the two ramp portions 142 are respectively positioned outside both sides of the width dimension of the saw assembly 130. The center of the flat portion 141 may be substantially at the same vertical height as the axis of symmetry of the chain guide plate 130, or may be provided at different vertical heights. In the illustrated embodiment, the flat surface described above includes the platform portion 141 and the surface of the ramp portion 142 on the side away from the body 100. In one embodiment, the flat surface may only include the surface of the platform portion 141 on the side away from the body 100.

[0031] The support plate 140 is a metal piece (preferably a metal casting) and can be configured to be removable. For example, the support plate 140 can be made of aluminum, copper, iron, steel, or their alloys. If needed, the support plate 140 can be fixed to one end of the body 100 by bolts (not shown). If not needed, the support plate 140 can be removed by loosening the bolts. The bolt holes 103 on the body 100 can also be configured to install other desired saw components, including but not limited to log teeth, etc. The positions of the bolt holes can be configured to be symmetrically disposed on both sides of the axis of symmetry of the chain guide plate 130, or can be configured to have an asymmetric position relative to the axis of symmetry of the chain guide plate 130.

[0032] In use, the support plate 140 abuts against the workpiece to be processed, and the platform portion 141 and the slope portion 142 provide a rotation center for the saw assembly. The user can operate the saw assembly to perform a small-range rotational movement and a swinging movement centered on the support plate 140. This is advantageous when the shape of the workpiece is a cube, a regular cube, etc. Such movements are conducive to fine-tuning the position and angle of the saw assembly, so as to process the workpiece into a desired shape. The forward shift of the center of gravity of the machine and the design of the first handle 110 make the operation labor-saving and convenient for single-handed operation. Coupled with the setting of the support plate 140 in this application, it is particularly suitable for being conveniently and flexibly used as a cutting machine for lightweight concrete bricks such as autoclaved aerated concrete (AAC).

[0033] Figure 2 is Figure 1 A perspective view after the assembly of the illustrated embodiment. As shown, the body 100 includes a first section 101 and a second section 102. The first section 101 is configured to extend along a first axis A, and the second section 102 is configured to extend along a second axis B. The chain guide plate 130 is also configured to extend substantially along the first axis A, and the support plate 140 also protrudes from one end of the body 110 at a first height in the direction of the first axis A. The first height at which the support plate 140 protrudes is Figure 2 represented by H1 in, and the first height H1 can be in the range of 5 - 15 mm. A motor (not shown) may also be provided inside the body 100, and the motor shaft of the motor may also be configured to extend substantially along the second axis B. In addition, both ends of the first handle 110 can be respectively attached to the first section 101 and the second section 102.

[0034] A predetermined angle may be formed between the first section 101 and the second section 102, and the predetermined angle can be in the range of 90 degrees to 175 degrees. The predetermined angle includes but is not limited to 100 degrees, 110 degrees, 120 degrees, 150 degrees, 160 degrees, 170 degrees, etc. By forming a predetermined angle between the first section 101 and the second section 102, the center of the body 100 can be offset as a whole relative to the first handle 110 in the direction towards the chain guide plate 130. In other words, the center of gravity of the saw assembly will migrate as a whole. This shortens the force arm caused by gravity during the operation of the saw assembly, thereby reducing the force required to operate the saw assembly and being beneficial to the user's operation. In addition, the above structure also shortens the dimension of the body 110 in the direction indicated by the first axis A, so that the saw assembly as a whole has a more compact structure.

[0035] Figure 3 is Figure 2Left view of the illustrated embodiment. As shown, the support plate 140 has a first width W1, and the support plate 140 is spaced apart from the chain guide 130 by a first distance D1. In one embodiment, the first width W1 is in the range between 5 mm and 50 mm. In another embodiment, the first distance D1 is in the range between 5 mm and 50 mm. In addition, Figure 3 It is also schematically shown that the width dimension of the chain guide 130 in the vertical direction is smaller than the length dimension of the flat portion 141 in the vertical direction, and the inclined portions 142 protrude from both sides of the width dimension of the chain guide 130 respectively.

[0036] In use, the user can hold the saw assembly by one of the handles and selectively adjust the inclination angle and position of the chain guide 130 with the center of the support plate 140 as the pivot. The saw assembly of the present application provides various structures facilitating the above operations and is beneficial to improving the user experience and work efficiency.
