Description

Technical Field

[0001] This utility model relates to the field of chainsaw technology, specifically to a chainsaw base plate that prevents the saw kerf from chipping. Background Technology

[0002] The base plate of a chainsaw (also called the chainsaw guide plate or chainsaw base) is an important component of a power saw tool. It is usually the flat part below the saw blade. Its function is to support the entire body of the chainsaw and help maintain stability during cutting. The design of the base plate determines the direction and depth of the saw blade during cutting, and also affects the cutting accuracy and safety.

[0003] In existing technologies, some chainsaws experience high-frequency vibrations in the saw blade during use, which makes edge chipping of the saw blade quite noticeable when sawing wood. This chipping results in uneven edges on the cut wood, affecting aesthetics and processing quality. This is especially problematic in projects requiring high precision and appearance, necessitating additional processing afterward. To address this, we propose a chainsaw base plate to prevent edge chipping of the saw blade. Utility Model Content

[0004] The purpose of this utility model is to provide a base plate for an electric saw that prevents chipping of the saw kerf, thereby solving the problem mentioned in the background art where the saw blade vibrates at high frequency during use, resulting in significant chipping of the saw kerf when sawing wood, which affects the appearance and processing quality and requires additional processing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a base plate for an electric saw that prevents chipping of the saw cut, comprising a saw, a saw blade mounted on the front side of the saw, a cutting plate fixedly connected to the bottom end of the saw, two pressing plates slidably connected inside the cutting plate, a pushing and fitting mechanism for pushing the pressing plates to press tightly against the saw blade inside the cutting plate, a fixing mechanism for fixing the two pressing plates inside the cutting plate, and a limiting mechanism for fixing the two pressing plates inside the cutting plate.

[0006] The pushing and fitting mechanism includes four mounting posts fixedly connected inside the cutting plate, and each of the four mounting posts is fitted with a pushing spring.

[0007] Each of the four mounting columns has a sliding block slidably connected to its outer side, and each of the four sliding blocks has a driving column fixedly connected to its bottom end.

[0008] Each of the two extrusion plates has two drive holes inside, and four drive columns are slidably connected inside the four drive holes.

[0009] The fixing mechanism includes six screws threaded inside the cutting plate, and three sliding grooves are provided inside each of the two extrusion plates. The outer sides of the six screws are slidably connected to the inside of the six sliding grooves.

[0010] The limiting mechanism includes two slidably connected drive bars inside the cutting plate. The cutting plate is equipped with two push springs for pushing the drive bars. The bottom end of the drive bars is fixedly connected to two drive protrusions.

[0011] The cutting plate has four sliding blocks inside, each with a drive groove. The four drive protrusions are slidably connected inside the four drive grooves. The blocks and the extrusion plate are snapped together, and the bottom of the drive bar is fixedly connected to a push post.

[0012] This utility model has at least the following beneficial effects: By having the push spring push the sliding block and the drive column, the drive column engages with the drive hole, causing the pressing plate to be constantly in close contact with the saw blade. This reduces the high-frequency vibration of the saw blade during operation, alleviates chipping of the saw edge when sawing wood, and makes the edges of the cut wood neater, improving aesthetics and processing quality, and eliminating the need for additional subsequent processing.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] The push-fitting mechanism 5 includes four mounting posts 501 fixedly connected inside the cutting plate 3. The mounting posts 501 are designed to facilitate the installation of push springs 502 and sliding blocks 503. Push springs 502 are sleeved on the outer side of the four mounting posts 501. The push springs 502 are designed to facilitate the push of sliding blocks 503.

[0018] Sliding blocks 503 are slidably connected to the outer sides of the four mounting posts 501. The sliding blocks 503 are designed to facilitate the installation of the drive posts 504. The bottom ends of the four sliding blocks 503 are fixedly connected to the drive posts 504. The drive posts 504 are designed to cooperate with the drive holes 505 under the drive of the sliding blocks 503, thereby driving the extrusion plate 4 to fit tightly against the saw blade 2.

[0019] Two drive holes 505 are opened inside each of the two extrusion plates 4. The drive holes 505 are designed to accommodate the drive columns 504. The four drive columns 504 are slidably connected inside the four drive holes 505 respectively.

[0020] The fixing mechanism 6 includes six fixing screws 601 threaded into the cutting plate 3. The fixing screws 601 are designed to fix the extrusion plates 4. Each of the two extrusion plates 4 has three sliding grooves 602 inside. The sliding grooves 602 are designed to facilitate the sliding of the fixing screws 601 within them. The outer sides of the six fixing screws 601 are slidably connected to the six sliding grooves 602. When using the saw 1, the saw 1 is started first, which drives the saw blade 2 to rotate, thus cutting the wood. When the saw blade 2 cuts the wood, it generates high-frequency vibrations, which then push... The moving spring 502 pushes the sliding block 503, which in turn drives the driving column 504. The driving column 504 then drives the pressing plate 4 through the driving hole 505, ensuring that the two pressing plates 4 are always in close contact with both sides of the saw blade 2. By having the moving spring 502 push the sliding block 503 and the driving column 504, the driving column 504 engages with the driving hole 505, causing the pressing plates 4 to be in close contact with the saw blade 2 at all times. This reduces the high-frequency vibration of the saw blade 2 during operation, reduces the chipping of the saw edge when sawing wood, and makes the edges of the cut wood board neater, improving the aesthetics and processing quality, and eliminating the need for additional subsequent processing.

The pushing springs 702 are designed to push the driving bars 701, thereby driving the two driving protrusions 703. The bottom end of the driving bars 701 is fixedly connected to the two driving protrusions 703. The driving protrusions 703 are designed to drive the locking block 704 under the action of the driving bars 701.

[0022] The cutting plate 3 has four sliding blocks 704 inside. The blocks 704 are designed to fix the extrusion sheet 4. Each of the four blocks 704 has a drive groove 705 inside. The drive groove 705 is designed to facilitate the engagement of the drive protrusion 703 with the drive groove 705, thereby driving the blocks 704. The four drive protrusions 703 are slidably connected inside the four drive grooves 705 respectively. The blocks 704 and the extrusion sheet 4 are engaged. The bottom end of the drive bar 701 is fixedly connected to a toggle post 706. The toggle post 706 is designed to facilitate the toggle of the drive bar 701.
