Description

Technical Field

[0001] This invention relates to the field of garden equipment and tools, and in particular to a lawnmower blade disassembly clamp. Background Technology

[0002] Mechanical equipment plays an indispensable role in both production and daily life. Among them, the most widely used mechanical equipment is the electric motor. Mechanical equipment comes in many types, generally categorized into ten types according to its purpose, mainly including power machinery, metal cutting machinery, metal forming machinery, and agricultural machinery. Lawn mowers belong to the category of agricultural machinery. A lawn mower is a mechanical tool used for trimming lawns and vegetation, with an efficiency 8 to 10 times higher than manual weeding, a lower rate of seedling damage, and a higher rate of clean removal. The cutter head is mounted on the wheels, and the motor is mounted on the cutter head. The blades are mounted on the motor's output shaft. The high-speed rotation of the motor greatly increases the speed of weeding, saving workers' time and reducing manpower. The cutting blades are located around the perimeter of the cutter head and often use a swinging blade design, meaning the blades swing and cut on the cutter head as it rotates. After long-term use, the blades need to be replaced due to wear or rust. However, there are currently no specialized disassembly and assembly tools. To ensure safety, users are required to wear cut-resistant gloves when disassembling and assembling, and use an electric screwdriver to remove the blades. This is not only inefficient, but the blade disc can also easily rotate with the electric screwdriver during disassembly, posing a risk of cutting the user's hands. Summary of the Invention

[0003] Therefore, it is necessary to provide a lawnmower blade removal clamp to address the above problems and protect users from cuts when removing blades from the cutter head.

[0004] A lawnmower blade removal clamp for holding the blade disc includes:

[0005] First hand holding the stick;

[0006] The second hand lever is hinged to the first hand lever;

[0007] The first pressure plate is connected to the first hand handle. The first pressure plate is used to press against the side of the blade mounted on the cutter head. The first pressure plate has a receiving groove for accommodating the blade.

[0008] The second pressure plate is connected to the second hand handle and is used to press against the side of the cutter head away from the blade.

[0009] The aforementioned lawnmower blade removal clamp, by pressing the first hand lever and the second hand lever against each other, allows the first and second pressure plates to clamp the blade disc in the thickness direction, fixing the blade disc in place. This prevents the blade disc from rotating when the electric screwdriver removes the fixing component, avoiding misalignment between the electric screwdriver and the fixing component. At the same time, the clamp is secure, and the user holding the first and second hand levers is far away from the blade disc, making them less likely to be cut.

[0010] In one embodiment, the first pressure plate includes: a first limiting plate, a second limiting plate opposite to the first limiting plate, and a connecting plate connecting the first limiting plate and the second limiting plate. The first limiting plate, the second limiting plate, and the connecting plate form the receiving groove. The connecting plate is connected to the first hand handle. The first limiting plate has a first pressing part protruding from one side facing the second pressure plate, and the second limiting plate has a second pressing part protruding from one side facing the second pressure plate. The first pressing part and the second pressing part respectively press against the protrusions on both sides of the fixing groove. Both the first pressing part and the second pressing part are strip-shaped, which can stably support the protrusions on both sides of the fixing groove and clamp the upper side of the cutter head. In some embodiments, positioning grooves can be formed on the first pressing part and the second pressing part. The positioning grooves cooperate with the protrusions on both sides of the fixing groove for greater stability when clamping the cutter head.

[0011] In one embodiment, the lawnmower blade removal clamp further includes a clamping elastic element, one end of which is connected to the first pressure plate or the first hand lever, and the other end of which is connected to the second pressure plate or the second hand lever. The clamping elastic element provides a spring force that brings the first and second pressure plates closer together. This ensures that when the first and second pressure plates press against the blade disc, they exert pressure on the blade disc, increasing the friction between the first and second pressure plates and the blade disc, and improving the stability of the clamping.

[0012] In one embodiment, the clamping elastic element is a tension spring connected between the first pressure plate and the second hand lever. The clamping elastic element provides a spring force that brings the first and second pressure plates closer together. One end of the tension spring is connected to a connecting portion on the first pressure plate to avoid incorrect spring angles caused by connecting it to the first folded portion. The other end of the tension spring is connected to the second straight portion, or it can be connected to the second pressure plate. In this embodiment, only the connection of the tension spring to the second straight portion is used as an example, allowing the first and second pressure plates to clamp the cutter head more stably.

[0013] In one embodiment, the first handheld lever includes a first zigzag portion connected to the first pressure plate and a first straight portion for the user to grip. The second handheld lever includes a second connecting portion connected to the second pressure plate and a second zigzag portion for the user to grip. The connection point between the first zigzag portion and the first straight portion is a first hinge point, and the connection point between the second connecting portion and the second zigzag portion is a second hinge point. The first hinge point and the second hinge point are hinged together by a hinge member. Since the cutter head is disc-shaped, when clamping the cutter head, the first pressure plate and the second pressure plate clamp the upper and lower sides of the cutter head respectively, and are in a nearly parallel state. If both the first handheld lever and the second handheld lever are straight rods, the first pressure plate and the second pressure plate will definitely form an angle with each other, causing unstable clamping. Both the first handheld lever and the second handheld lever are partially bent. The first zigzag portion is used to adjust the angle of the first pressure plate so that the first pressure plate can be parallel to the second pressure plate, thus better clamping the cutter head.

[0014] In one embodiment, the first pressure plate is arranged parallel to the first straight section. When the first pressure plate and the second pressure plate clamp the cutter head, the first pressure plate and the second pressure plate are parallel, and the second pressure plate and the first straight section are located on the same plane. When the first pressure plate and the second pressure plate clamp the cutter head, the second pressure plate and the first straight section are located on the same plane. Since the second pressure plate is connected to the second straight section, the second pressure plate and the second straight section are always located on the same plane, so the second straight section and the first straight section are collinear. The bottom of the fixture is in a straight line, which makes it more stable.

[0015] In one embodiment, a locking nut is provided on the side of the cutter head away from the blade, and a receiving hole is provided on the second pressure plate for receiving the locking nut. When the second pressure plate abuts against the bottom of the cutter head, the locking nut is located in the receiving hole, which limits the second pressure plate and prevents the second pressure plate and the clamp from swinging left and right.

[0016] In one embodiment, an adjustment assembly is provided between the first pressure plate and the second pressure plate. The adjustment assembly is used to adjust the distance between the first pressure plate and the second pressure plate. The adjustment assembly compresses the first pressure plate 5 and the second pressure plate 6 towards each other, so that the first pressure plate and the second pressure plate press against the cutter head with a certain force, thereby improving the stability of clamping.

[0017] In one embodiment, the adjusting assembly includes: a bolt passing through the first pressure plate from the second pressure plate; and an adjusting nut disposed on the side of the first pressure plate, the adjusting nut abutting against the first pressure plate. Rotating the adjusting nut moves its position on the bolt to adjust the distance between the first and second pressure plates. By moving the bolt, the distance between the first and second pressure plates can be adjusted. When the first and second pressure plates clamp the cutter head, it prevents the first and second hand levers from being released due to user error, causing the first and second pressure plates to move away from each other, resulting in unstable clamping, causing the cutter head to rotate, and potentially cutting the user. Before clamping the cutter head, the adjusting nut is rotated to its highest position, allowing the first and second hand levers to rotate freely relative to each other. The user can adjust the first and second hand levers to clamp the cutter head using the first and second pressure plates. After clamping the cutter head, rotating the adjusting nut abuts against the first pressure plate, causing the first and second pressure plates to press against the cutter head with a certain force, improving clamping stability.

[0018] In one embodiment, the cutter head has a fixing groove, and the blade is fixed in the fixing groove by a fixing member. The cutter head also has a first rotating groove and a second rotating groove. The blade has a first end and a second end, which are located on both sides of the fixing member. The first end of the blade extends into the first rotating groove, and the second end of the blade extends into the second rotating groove. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the scope of protection of this invention.

[0025] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] The first embodiment of the present invention relates to a lawnmower blade removal clamp for protecting the user from cuts when removing blades from the lawnmower's blade disc.

[0028] like Figure 1 and Figure 2 As shown, the lawnmower's blade disc 1 is circular, with multiple blades 2 arranged around it. The blades 2 can be fixedly mounted on the blade disc 1 or rotatably mounted on it. In this embodiment, the blade disc 1 is rotatably mounted on it as an example. The blades 2 are mounted on the blade disc 1 by a fixing member 21, and some of them extend beyond the blade disc 1. When the lawnmower is working, the blade disc 1 rotates around its own axis, driving the blades 2 to rotate. The blades 2 can also swing around the fixing member 21 to increase the cutting area. After long-term use, the blades 2 need to be replaced due to wear or rust. The common method is to remove the blades 2 by rotating the fixing member 21 on the blades 2 with an electric wrench. However, since the blade disc 1 is rotatably mounted on the lawnmower, rotating the fixing member 21 with an electric wrench can easily cause the blade disc 1 to rotate, resulting in misalignment with the fixing member 21. If the user holds the blade disc 1, the efficiency is low and it is very easy to cut their hands.

[0029] The lawnmower blade removal clamp is used to hold and fix the blade disc 1 during blade removal 2, preventing the blade disc 1 from rotating and improving the removal efficiency of the blade 2. The removal tool includes: a first hand lever 3, a second hand lever 4 hinged to the first hand lever 3, a first pressure plate 5 connected to the first hand lever 3, and a second pressure plate 6 connected to the second hand lever 4. The entire removal tool is pliers-like. When the user holds the first hand lever 3 and the second hand lever 4, the first pressure plate 5 and the second pressure plate 6 move closer together, clamping the edge of the blade disc 1 and fixing it in place. The first pressure plate 5 is used to press against the side of the blade disc 1 where the blade 2 is mounted. Figure 1 The middle is the upper side, and the second pressure plate 6 is used to press against the side of the cutter head 1 away from the blade 2. Figure 1 The middle section is located on the lower side. The first pressure plate 5 and the second pressure plate 6 clamp the blade disc 1 in the thickness direction to fix the blade disc 1, so that the blade disc 1 will not rotate when the electric screwdriver removes the fixing part 21, thus preventing the electric screwdriver from being misaligned with the fixing part 21. At the same time, the clamping is stable, and the user holds the first hand handle 3 and the second hand handle 4 away from the blade disc 1, making it less likely to be cut.

[0030] Combination Figure 2 and Figure 3 The first pressure plate 5 has a receiving groove 54 for accommodating the blade 2. The first pressure plate 5 includes: a first limiting plate 51, a second limiting plate 52 opposite to the first limiting plate 51, and a connecting plate 53 connecting the first limiting plate 51 and the second limiting plate 52. The first limiting plate 51, the second limiting plate 52, and the connecting swing rod form the receiving groove 54. The receiving groove 54 is a groove with an opening. When clamping the cutter head 1, the opening of the receiving groove 54 of the first pressure plate 5 is aligned with the blade 2 to be disassembled on the cutter head 1. The user squeezes the first hand lever 3 and the second hand lever 4 to hold the first pressure plate 5 against the upper side of the cutter head 1. The blade 2 is located in the receiving groove 54. When disassembling the blade 2, the rotating tool rotates the fixing member 21 of the blade 2 located in the receiving groove 54. The blade 2 swings in the receiving groove 54. The receiving groove 54 restricts the position of the blade 2 to prevent the blade 2 from swinging too much or flying out and cutting the user.

[0031] It is worth noting that the first limiting plate 51 protrudes 14 on the side facing the second pressure plate 6 to form a first pressing part 511, and the second limiting plate 52 protrudes 14 on the side facing the second pressure plate 6 to form a second pressing part. The cutter head 1 has a fixing groove 11, and the blade 2 is fixed in the fixing groove 11 by a fixing member 21. The cutter head 1 also has a first rotating groove 12 and a second rotating groove 13. The first rotating groove 12 and the second rotating groove 13 are located on both sides of the fixing groove 11 in the radial direction of the cutter head 1. The first end of the blade 2 extends into the first rotating groove 12, and the second end of the blade 2 extends into the second rotating groove 13. The width of the first rotating groove 12 and the second rotating groove 13 in the circumferential direction of the cutter head 1 is greater than that of the fixing groove 11, so that the protrusions 14 on both sides of the fixing groove 11 are between the first rotating groove 12 and the second rotating groove 13. The first pressing part 511 and the second pressing part press against the protrusions 14 on both sides of the fixing groove 11 respectively. The first pressing part 511 and the second pressing part are both strip-shaped, which can stably hold the protrusions 14 on both sides of the fixing groove 11 and clamp the upper side of the cutter head 1. In some embodiments, positioning grooves may be provided on the first pressing part 511 and the second pressing part. The positioning grooves cooperate with the protrusions 14 on both sides of the fixing groove 11, making the clamping of the cutter head 1 more stable.

[0032] Among them, such as Figure 1 As shown, the first hand lever 3 includes a first zigzag section 31 connected to the first pressure plate 5 and a first straight section 32 for the user to grip. The second hand lever 4 includes a second connecting section 41 connected to the second pressure plate 6 and a second zigzag section 42 for the user to grip. The connection point between the first zigzag section 31 and the first straight section 32 is the first hinge point, and the connection point between the second connecting section 41 and the second zigzag section 42 is the second hinge point. The first hinge point and the second hinge point are hinged together by a hinge member. Since the cutter head 1 is disc-shaped, when clamping the cutter head 1, the first pressure plate 5 and the second pressure plate 6 clamp the upper and lower sides of the cutter head 1 respectively, and are in a nearly parallel state. If the first hand lever 3 and the second hand lever 4 are both straight rods, the first pressure plate 5 and the second pressure plate 6 will definitely form an angle with each other, causing the clamping to be unstable. The first hand lever 3 and the second hand lever 4 are both partially bent. The first zigzag section 31 is used to adjust the angle of the first pressure plate 5 so that the first pressure plate 5 can be parallel to the second pressure plate 6, and better clamp the cutter head 1. The second bend section 42 is used to adjust the angle of the second grip lever, so that the distance between the first grip lever and the second grip lever is convenient for the user to hold comfortably. In some embodiments, the second bend section 42 may also be connected to the second straight section 43, so that the ends of the first grip lever 3 and the second grip lever 4 are both straight, which is convenient for the user to hold.

[0033] It is worth noting that the first pressure plate 5 is arranged parallel to the first straight section 32. When clamping the tool disc 1, the first pressure plate 5 is in a horizontal state, and the first straight section 32 is also in a horizontal state. At this time, the first pressure plate 5 is parallel to the second pressure plate 6, and the second pressure plate 6 is parallel to the first straight section 32. When the first pressure plate 5 and the second pressure plate 6 clamp the tool disc 1, the second pressure plate 6 and the first straight section 32 are located on the same plane. Since the second pressure plate 6 is connected to the second straight section 43, the second pressure plate 6 and the second straight section 43 are always located on the same plane, so the second straight section 43 and the first straight section 32 are collinear. The bottom of the fixture is in a straight line, which makes it more stable.

[0034] The cutter head 1 has a locking nut on the side opposite to the blade 2. The locking nut is generally injection molded at the bottom of the cutter head 1. The fixing part 21 can be a bolt. The bolt passes through the blade 2 and cooperates with the locking nut on the cutter head 1 to complete the installation of the fixing part 21. In order to better clamp the cutter head 1, the second pressure plate 6 has a storage hole for storing the locking nut. The storage hole can be a round hole or a hexagonal hole, etc. When the second pressure plate 6 abuts against the bottom of the cutter head 1, the locking nut is located in the storage hole, which limits the second pressure plate 6 and prevents the second pressure plate 6 and the clamp from swinging left and right.

[0035] To improve clamping stability, the lawnmower blade removal clamp in this embodiment further includes a clamping elastic element 7. One end of the clamping elastic element 7 is connected to the first pressure plate 5 or the first hand lever 3, and the other end is connected to the second pressure plate 6 or the second hand lever 4. The clamping elastic element 7 provides a spring force to bring the first pressure plate 5 and the second pressure plate 6 closer together. This ensures that when the first pressure plate 5 and the second pressure plate 6 press against the blade disc 1, they exert a certain pressure on the blade disc 1, increasing the friction between the first pressure plate 5 and the second pressure plate 6 and the blade disc 1, thus improving clamping stability. The clamping elastic element 7 is a tension spring, applying a spring force to bring the first pressure plate 5 and the second pressure plate 6 closer together. In this embodiment, one end of the tension spring is connected to the connecting part on the first pressure plate 5 to avoid incorrect tension spring angles caused by connecting it to the first folded part 31. The other end of the tension spring is connected to the second straight part 43, or it can be connected to the second pressure plate 6. In this embodiment, the tension spring is connected to the second straight part 43 as an example, allowing the first pressure plate 5 and the second pressure plate 6 to clamp the blade disc 1 more stably.

[0036] In some embodiments, the clamp can also press the first pressure plate 5 and the second pressure plate 6 together in other ways, such as by providing an adjustment assembly between the first pressure plate 5 and the second pressure plate 6 to adjust the distance between them and compress them towards each other. In this embodiment, the adjustment assembly includes: a bolt passing through the first pressure plate 5 from the second pressure plate 6; and an adjustment nut located on the side of the first pressure plate 5. The adjustment nut abuts against the first pressure plate 5. Rotating the adjustment nut moves its position on the bolt to adjust the distance between the first pressure plate 5 and the second pressure plate 6. By moving the bolt, the distance between the first pressure plate 5 and the second pressure plate 6 can be adjusted. When the first pressure plate 5 and the second pressure plate 6 clamp the cutter head 1, it prevents the first hand lever 3 and the second hand lever 4 from being released due to user error, causing the first pressure plate 5 and the second pressure plate 6 to move away from each other, resulting in unstable clamping, rotation of the cutter head 1, and potential injury to the user. Before clamping the cutter head 1, turn the adjusting nut to the highest position so that the first hand lever 3 and the second hand lever 4 can rotate freely relative to each other. The user can adjust the first hand lever 3 and the second hand lever 4 to clamp the cutter head 1 through the first pressure plate 5 and the second pressure plate 6. After clamping the cutter head 1, turn the adjusting nut to abut against the first pressure plate 5 so that the first pressure plate 5 and the second pressure plate 6 press against the cutter head 1 with a certain force, thereby improving the stability of clamping.

[0037] The lawnmower blade removal clamp in this embodiment can stably clamp the blade disc 1 when removing the blades 2 from the blade disc 1, preventing the blade disc 1 from rotating and cutting the user; the opening of the receiving groove 54 on the first pressure plate 5 restricts the position of the blades 2 during removal, preventing the blade disc 1 from flying out or the blades 2 from swinging and cutting the user; the setting of the first pressing part 511 and the second pressing part makes the clamping of the blade disc 1 by the first pressure plate 5 more stable; the bending setting of the first hand handle 3 and the second hand handle 4 makes the first pressure plate 5 and the second pressure plate 6 parallel and stably clamp the blade disc 1; the setting of the pressing elastic element 7 or the adjusting component makes the first pressure plate 5 and the second pressure plate 6 press the blade disc 1 under a certain force, improving the clamping stability.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
