[0049] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0050] See Figures 3 to 13 This embodiment provides a saw blade mounting structure, including a fixed base 10, a first clamping plate 20, and a locking member. The first surface of the fixed base 10 is provided with a mounting groove 11, which extends along a first direction and is parallel to the first surface. The side wall of the mounting groove 11 is recessed or protruding with a first limiting part 12. The first clamping plate 20 includes a first plate body 21 and a second limiting part 22 disposed on the first plate body 21. The second limiting part 22 extends along the first direction and is slidably disposed in the mounting groove 11. Part of the second limiting part 22 cooperates with the first limiting part 12 to restrict the first clamping plate 20 from detaching from the fixed base 10 along a second direction, which is perpendicular to the first surface. The locking member is threadedly connected to the first clamping plate 20 and passes through the saw blade 50 and abuts against the saw blade 50 to lock the first clamping plate 20 and the saw blade 50.

[0051] The saw blade 50 is connected to the first clamping plate 20 by a locking device. The first clamping plate 20 is connected to the fixed base 10 by a first limiting part 12 and a second limiting part 22. Since the side wall of the mounting groove 11 is recessed or protruding with the first limiting part 12, the second limiting part 22 is slidably disposed in the mounting groove 11. Part of the second limiting part 22 cooperates with the first limiting part 12 to restrict the first clamping plate 20 from detaching from the fixed base 10 in the second direction. Therefore, the cooperation of the first limiting part 12 and the second limiting part 22 plays a limiting role in the first clamping plate 20 in the second direction, reducing the number of bolts used and improving the stability and safety of the saw blade 50 installation.

[0052] In this embodiment, the sidewall and bottom wall of the mounting groove 11 are set at an acute angle to form a limiting groove as the first limiting part 12. Limiting protrusions 221 are formed on both sides of the second limiting part 22, and the limiting protrusions 221 are inserted into the limiting groove. The acute angle between the sidewall and bottom wall of the mounting groove 11 facilitates manufacturing. Because the acute angle between the sidewall and bottom wall of the mounting groove 11 makes it a trapezoidal groove, it can limit the limiting protrusions 221. The cross-sectional shape of the limiting groove is triangular. To ensure a good fit between the limiting protrusions 221 and the limiting groove, the cross-section of the limiting protrusions 221 is set as triangular.

[0053] In other embodiments, the sidewall of the mounting groove 11 is recessed with a groove, and the second limiting part 22 is provided with a protrusion that inserts into the groove. In other embodiments, the sidewall of the mounting groove 11 is protruding with a protrusion, and the second limiting part 22 is provided with a groove that inserts into the groove. The cross-sectional shape of the groove can be semi-circular, rectangular, or triangular, and the corresponding cross-sectional shape of the protrusion can be semi-circular, rectangular, or triangular.

[0054] With reference to the fixed base 10, a first direction, a second direction, and a third direction are defined. In the figure, X represents the first direction, Y represents the third direction, and Z represents the second direction. The mounting groove 11 extends along the first direction and can penetrate to at least one end of the fixed base 10, facilitating the installation of the second limiting part 22 into the mounting groove 11. In this embodiment, the mounting groove 11 extends to both ends of the fixed base 10 along the first direction. In other embodiments, the mounting groove 11 does not penetrate to the end of the fixed base 10, but instead, an insertion groove communicating with the mounting groove 11 is formed at one end of the first surface. The insertion groove is wider than the mounting groove 11, thus enabling the limiting protrusion 221 to be inserted into the insertion groove first and then slid into the mounting groove 11.

[0055] Because the sidewall of the mounting groove 11 is recessed or protruding with a first limiting part 12, a portion of the second limiting part 22 cooperates with the first limiting part 12 to limit the first clamping plate 20 in the second direction. The cooperation of the first limiting part 12 and the second limiting part 22 does not affect the sliding of the first clamping plate 20 along the fixed base 10, so both the first limiting part 12 and the second limiting part 22 extend in the first direction.

[0056] Existing saw blade installation structures, such as Figure 1 and Figure 2 As shown, the front clamping plate 100, rear clamping plate 200, saw blade, and mounting base 300 are fixed by a main bolt. The mounting base 300 has a slotted hole 301 corresponding to the position of the main bolt, facilitating adjustment of the main bolt's position. Typically, a tensioning bolt is installed on the side of the mounting base 300 away from the front clamping plate 100. This tensioning bolt presses against the main bolt, and the saw chain is tensioned by adjusting the position of the main bolt. In actual use, with the mounting base 300 at the rear and the front clamping plate 100 at the front, it becomes difficult to adjust the tensioning bolt's position if the main bolt loosens.

[0057] In this embodiment, the first clamping plate 20 further includes a tensioning part 23, which is disposed on one side of the first plate body 21 along a third direction. A tensioning member 40 is threadedly connected to the fixed base 10. The tensioning member 40 can move along a first direction and abut against the tensioning part 23. The third direction is parallel to the first surface and perpendicular to the first direction. By disposing the tensioning part 23 on one side of the first plate body 21 along a third direction, which is parallel to the first surface and perpendicular to the first direction, it is convenient to adjust the position of the tensioning member 40. The cooperation between the tensioning part 23 and the tensioning member 40 makes it easier to adjust the tension of the saw blade 50 during use without it coming off, ensuring the stability of the saw chain and improving the safety and convenience of operation.

[0058] In some embodiments, the tensioning member 40 rigidly abuts against the tensioning portion 23. In some embodiments, the tensioning member 40 elastically abuts against the tensioning portion 23. Exemplarily, an elastic member is provided inside the tensioning portion 23, and one end of the tensioning member 40 can be inserted into the tensioning portion 23 to abut against the elastic member. Exemplarily, an elastic member is provided outside the tensioning portion 23, and one end of the tensioning member 40 abuts against the elastic member.

[0059] Exemplarily, the fixed base 10 includes a mounting portion 13, and a tensioning member 40 is threadedly connected to the mounting portion 13. The mounting portion 13 and the tensioning portion 23 are disposed opposite each other, and the tensioning member 40 is a bolt screwed into the mounting portion 13, with the bolt shank abutting against the tensioning portion 23. The tensioning member 40 can limit the first clamping plate 20 to prevent it from moving forward in the first direction. In actual use, one end of the saw blade 50 is disposed on the first clamping plate 20, and the other end of the saw blade 50 extends away from the fixed base 10. The saw chain is wound around the saw blade 50, and the saw chain can limit the saw blade 50 from moving backward in the first direction. When it is necessary to adjust the position of the first clamping plate 20, the tensioning member 40 is rotated to move the tensioning member 40 closer to or away from the tensioning portion 23.

[0060] Existing saw blade installation structures, such as Figure 1 and Figure 2 As shown, by opening oil supply holes 302 on the mounting base 300 and the rear clamping plate 200, and connecting the oil pipe to the oil supply holes 302 on the mounting base 300, the lubricating oil flows to the saw blade after passing through the mounting base 300 and the rear clamping plate 200. Due to the small space behind the mounting base 300 caused by the main bolt, the oil supply hole 302 is small, and the lubricating oil needs to pass through the mounting base 300 and the rear clamping plate 200 to reach the saw blade, resulting in a longer flow path.

[0061] In this embodiment, a clearance hole 14 is provided through the mounting groove 11 in the fixed base 10 along the second direction. The first clamping plate 20 is provided with a connected oil inlet hole 24 and an oil outlet hole 25. The oil inlet hole 24 is located on the side of the first clamping plate 20 near the clearance hole 14 and is connected to the clearance hole 14. The oil outlet hole 25 is located on the side of the first clamping plate 20 away from the clearance hole 14 and is used to supply oil to the saw blade 50. The oil supply pipe can pass through the clearance hole 14 and connect to the oil inlet hole 24, thereby supplying oil to the oil inlet hole 24. The lubricating oil flows along the oil inlet hole 24 to the oil outlet hole 25 and flows directly onto the saw blade 50. The lubricating oil only needs to pass through the first clamping plate 20 to reach the saw blade 50, shortening the flow path.

[0062] The size of the clearance hole 14 can be set according to actual needs. The fixed base 10 has a large space to facilitate the opening of a large clearance hole 14. The oil supply pipe passes through the clearance hole 14. When the first clamping plate 20 slides relative to the fixed base 10, the oil supply pipe moves within the clearance hole 14. The stroke setting of the first clamping plate 20 ensures that the oil supply pipe will not interfere with the fixed base 10. In addition, the oil supply pipe also plays a limiting role for the first clamping plate 20, preventing the first clamping plate 20 from sliding excessively.

[0063] Specifically, an oil supply channel 26 is formed inside the first clamping plate 20. The oil inlet hole 24 is connected to the oil supply channel 26, and multiple oil outlet holes 25 are provided, all of which are connected to the oil supply channel 26. The arrangement of the oil supply channel 26 facilitates the distribution of multiple oil outlet holes 25, so that multiple positions of the saw blade 50 can be lubricated simultaneously, thereby improving lubrication efficiency.

[0064] This embodiment shows four oil outlet holes 25, but the number of oil outlet holes 25 can be set according to actual needs. The arrangement of multiple oil outlet holes 25 can also be set according to actual needs, such as in a straight line, a matrix, or a ring. The number of oil inlet holes 24 can be one or more; setting one oil inlet hole 24 is sufficient to meet the oil inlet requirements.

[0065] The oil supply channel 26 can extend in a straight line or a curve. For example, the oil supply channel 26 extends in a straight line, which facilitates processing and production. In this embodiment, the first plate 21 of the first clamping plate 20 is an integrally formed structure. When processing the oil supply channel 26, straight holes extending in a first direction and straight holes extending in a third direction are opened from the periphery of the first plate 21. Some of the straight holes can be intersected as needed. The openings at the periphery of the first plate 21 can be sealed with sealing plugs.

[0066] In some embodiments, the locking element may be a bolt, the head of which can abut against the saw blade 50. In some embodiments, the locking element may be a screw and a nut, the screw passing through the saw blade 50 and threadedly connected to the first clamping plate 20, and the nut being disposed on the screw and abutting against the saw blade 50.

[0067] To facilitate the connection of the saw blade 50, in some embodiments, the saw blade mounting structure further includes a second clamping plate 30. The second clamping plate 30 is disposed on the side of the first clamping plate 20 away from the fixed base 10. The saw blade 50 is disposed between the first clamping plate 20 and the second clamping plate 30. A locking member passes through the saw blade 50 and the second clamping plate 30 to lock the first clamping plate 20, the second clamping plate 30, and the saw blade 50. The second clamping plate 30 provides better protection for the saw blade 50.

[0068] In some embodiments, the locking element may be a bolt, the head of which can abut against the second clamping plate 30. In some embodiments, the locking element may be a screw and a nut, the screw passing through the saw blade 50 and the second clamping plate 30 and threadedly connected to the first clamping plate 20, and the nut being disposed on the screw and abutting against the second clamping plate 30.

[0069] For example, the first clamping plate 20 has a first mounting hole 27 through which a locking member can pass, and the second clamping plate 30 has a second mounting hole 31 through which a locking member can pass. The locking member passes through the second mounting hole 31 and is threadedly connected to the first mounting hole 27.

[0070] To prevent the second clamping plate 30 from shifting due to rotation around the locking member, at least two locking members can be provided. In this embodiment, two locking members are provided, and the two locking members are spaced apart along a first direction. In other embodiments, the two locking members are spaced apart along a third direction.

[0071] Existing saw blade mounting structures typically have round holes drilled in the saw blade for mounting bolts. When disassembling the saw blade, it is necessary to remove the bolts and the front clamping plate 100 to remove the saw blade.

[0072] In this embodiment, the locking member has a threaded portion, and a positioning plane is provided on the outer peripheral surface of a portion of the threaded portion. A positioning groove 51 is provided at the end of the saw plate 50. The positioning groove 51 extends along a first direction, and the locking member is located in the positioning groove. The sidewall of the positioning groove 51 is arranged opposite to the positioning plane to restrict the rotation of the locking member. When disassembling the saw plate 50, the locking member is loosened, and the saw plate 50 can be pulled out, making disassembly convenient.

[0073] Optionally, the locking mechanism consists of a screw and a nut. The screw passes through the saw blade 50 and the first clamping plate 20 and is threadedly connected to the first clamping plate 20. The nut is located on the screw and abuts against the saw blade 50. When disassembling the saw blade 50, the nut is loosened to pull the saw blade 50 out without removing the screw.

[0074] With the second clamping plate 30 in place, the saw blade 50 can be pulled out by loosening the nut without disassembling the second clamping plate 30 and the screw. When installing the saw blade 50, insert the saw blade 50 between the second clamping plate 30 and the first clamping plate 20, and then tighten the nut.

[0075] The reason for providing a positioning plane on the outer circumference of some threaded portions is to guide the saw blade 50. When installing the saw blade 50, it is slid along the first direction, causing the locking member to slide into the positioning groove 51, so that the side wall of the positioning groove 51 is positioned opposite to the positioning plane. The positioning plane cooperates with the positioning groove 51 to restrict the rotation of the locking member and also restrict the rotation of the saw blade 50. Therefore, the width of the positioning groove 51 is smaller than the outer diameter of the locking member.

[0076] The saw blade 50 has a positioning hole 52, and the second clamping plate 30 has a positioning protrusion 32, which is inserted into the positioning hole 52. The positioning protrusion 32, in conjunction with the positioning hole 52, ensures a more secure fixation between the second clamping plate 30 and the saw blade 50. To disassemble the saw blade 50, loosen the nut and lift the second clamping plate 30 to disengage the positioning protrusion 32 from the positioning hole 52, allowing the saw blade 50 to be pulled out without disassembling the second clamping plate 30 and the screw. To install the saw blade 50, insert it between the second clamping plate 30 and the first clamping plate 20, aligning the positioning protrusion 32 with the positioning hole 52. Then, press the second clamping plate 30 against the saw blade 50, ensuring the positioning protrusion 32 is inserted into the positioning hole 52, and finally tighten the nut.

[0077] The shape of the positioning protrusion 32 and the positioning hole 52 is not limited, as long as the positioning protrusion 32 can be inserted into the positioning hole 52 to achieve the positioning function. The number of positioning protrusions 32 and positioning holes 52 is not limited, and the positioning protrusions 32 and positioning holes 52 are set in a one-to-one correspondence.

[0078] The saw blade 50 is also provided with an oil guide hole 53, which extends through the saw blade 50 along the thickness direction to guide the lubricating oil on one side of the saw blade 50 to flow to the other side of the saw blade 50.

[0079] like Figure 14 As shown, this embodiment also provides a sawing device, including a body, a drive mechanism, and a sawing mechanism. The drive mechanism is disposed on the body and includes a motor and a sprocket. The motor is used to drive the sprocket to rotate. The sawing mechanism includes a saw chain, a saw blade 50, and the saw blade mounting structure described above. A fixed base 10 is fixed to the body. The sprocket is located on one side of the fixed base 10 along a first direction. One end of the saw blade 50 is disposed on a first clamping plate 20, and the other end of the saw blade 50 extends away from the sprocket. The saw chain is wound around the saw blade 50 and the sprocket.

[0080] The sprocket and saw blade 50 together support the saw chain to keep it taut. The tensioning part 23 of the first clamping plate 20 is located on the side of the tensioning member 40 away from the sprocket. When the saw chain is loose, rotating the tensioning member 40 pushes the tensioning part 23 away from the sprocket to achieve the tensioning effect.

[0081] In some embodiments, the sawing device is a chainsaw, which may be a handheld chainsaw. In some embodiments, the sawing device is a logging machine, which may be a semi-automatic logging machine. Figure 14 The image shows the saw clamp of a logging machine. It holds the wood with multiple jaws, and the sawing mechanism can cut the wood.

[0082] The sawing device also includes a lubrication system, with an oil supply pipe passing through the clearance hole 14 and communicating with the oil inlet hole 24. The lubrication system is also used to supply oil to the drive mechanism, which will not be described in detail here.

[0083] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
