Description

Technical Field

[0001] This utility model relates to the field of power tool technology, and in particular to a reciprocating saw that operates smoothly. Background Technology

[0002] A reciprocating saw is a common type of reciprocating power tool, mainly used for cutting various materials such as wood and metal, and is widely used in industries such as furniture manufacturing and interior decoration. During operation, the motion conversion mechanism of the reciprocating saw cleverly converts the rotational motion of the motor assembly into the linear reciprocating motion of the reciprocating rod, thereby driving the saw blade to perform efficient high-frequency cutting operations.

[0003] In traditional reciprocating saws, the saw blade working area is usually designed in an open manner. These reciprocating saws generate a large amount of flying sawdust when cutting wood. Specifically, this manifests as follows: (1) The high-speed moving saw blade will scatter the sawdust into the working area in a scattering manner, obstructing the operator's vision and increasing the risk of misoperation; (2) The sawdust accumulates in the cutting seam of the workpiece, which increases the friction between the saw blade and the wood, not only reducing the cutting efficiency, but also potentially causing the saw blade to overheat or even be damaged; (3) The flying sawdust pollutes the working environment, increases the cleaning cost, and poses a dust explosion hazard when working in a confined space. Although there are attempts to improve sawdust treatment in the existing technology, they all have obvious defects. For example, some products add a fixed baffle to the saw blade guard, which can limit some of the sawdust flying, but seriously obstructs the operator's vision; another solution uses a dust collection device fixedly installed under the baffle, which seriously affects the flexible use of the reciprocating saw. Utility Model Content

[0004] The purpose of this invention is to provide a reciprocating saw that operates smoothly, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A reciprocating saw that operates smoothly includes a reciprocating saw housing, a saw blade and a baffle connected to the front end of the reciprocating saw housing, and dust collection components disposed on both sides of the reciprocating saw housing near the front end.

[0007] The dust collection assembly includes a metal hose, a dust collection head connected to one end of the metal hose, and a hose connector that is detachably connected to the other end of the metal hose; the hose connector is integrally formed and connected to the reciprocating saw housing; the dust collection head is detachably connected to the vacuum cleaner hose.

[0008] Preferably, the metal hose is detachably snapped into the dust collection head for easy disassembly and storage.

[0009] Preferably, the dust collection head includes a flat dust collection port and a connecting tube, which are integrally formed and connected; the connecting tube is detachably connected to the vacuum cleaner hose; the outer wall of the connecting tube is provided with an annular snap-fit ​​groove; the end of the metal hose near the dust collection head is provided with a snap-fit ​​seat that matches the snap-fit ​​groove; the snap-fit ​​groove and the snap-fit ​​seat are detachably snap-fitted together, and the detachable snap-fit ​​structure is simple and easy to assemble and disassemble.

[0010] Preferably, the snap-fit ​​seat includes an open-top C-shaped clamp that matches the snap-fit ​​groove and an arc-shaped connecting plate that connects to the metal flexible hose; the snap-fit ​​groove of the connecting pipe is detachably snapped into the C-shaped clamp, providing a stable snap-fit ​​and facilitating disassembly and assembly.

[0011] Preferably, the inner wall of the C-shaped clamp is covered with an anti-slip layer to increase the connection stability between the dust collection head and the connecting pipe.

[0012] Preferably, the width of the dust collection port is not greater than the diameter of the connecting pipe, which can match the splashed wood chips of different materials and improve the wood chip collection efficiency.

[0013] Preferably, the width of the dust collection port is greater than the diameter of the connecting pipe to match the splashed wood chips of different materials and improve the wood chip collection efficiency.

[0014] Compared with existing technologies, the reciprocating saw of this application, which operates smoothly, has the following advantages:

[0015] This invention connects the dust collection head to the saw body via a flexible metal hose, enabling multi-degree-of-freedom directional adjustment of the dust collection head. During operation, the relative position of the dust collection head and the cutting point can be adjusted in real time according to the saw blade's cutting angle, ensuring that the path of wood chips flying is always within the dust collection coverage area. Compared to traditional fixed baffles, wood chip collection efficiency is greatly improved, and cutting deviations caused by obstructing the operator's view are avoided. Attached Figure Description

[0022] The following detailed description illustrates the specific implementation methods:

[0023] Example 1

[0024] like Figure 1-5 As shown in the figure, this embodiment demonstrates a reciprocating saw that operates smoothly, including a reciprocating saw housing 1, a saw blade 2 and a baffle 3 connected to the front end of the reciprocating saw housing 1, and dust collection components 4 disposed on both sides of the reciprocating saw housing 1 near the front end. The saw blade 2 and the baffle 3 both adopt conventional reciprocating saw structures. The dust collection components 4 collect sawdust splashed from the cutting part based on the negative pressure of a vacuum cleaner. During operation, in order to prevent obstruction of vision or avoid interference with the cutting path of the reciprocating saw, the dust collection components 4 can be installed on either side of the two sides of the reciprocating saw housing 1 as needed.

[0025] In this embodiment, the dust collection component 4 includes a metal hose 41, a dust collection head 42 connected to one end of the metal hose 41, and a hose connector 43 detachably connected to the other end of the metal hose 41. The hose connector 43 is integrally formed and connected to the reciprocating saw housing 1. The dust collection head 42 is detachably connected to the vacuum cleaner hose, using negative pressure to collect wood chips. In this embodiment, the metal hose 41 is a component that combines flexibility and support, with an outer rubber coating, allowing it to bend 360° and maintain its shape at any angle. In actual operation, the dust collection head 42 is adjusted to a suitable position according to different cutting angles, allowing for simultaneous cutting and wood chip collection, making it flexible and portable.

[0026] To further explain, in a further possible implementation of this embodiment, such as Figure 4-5 As shown, the metal hose 41 is detachably snapped into the dust collection head 42 for easy disassembly and storage. Furthermore, the dust collection head 42 includes a flat dust collection port 421 and a connecting tube 422, which are integrally formed and connected; the connecting tube 422 is detachably connected to the vacuum cleaner hose; the outer wall of the connecting tube 422 is provided with an annular snap-fit ​​groove 423; one end of the metal hose 41 near the dust collection head 42 is provided with a snap-fit ​​seat 411 that matches the snap-fit ​​groove 423; the snap-fit ​​groove 423 and the snap-fit ​​seat 411 are detachably snapped into each other, resulting in a simple structure and easy assembly and disassembly.

Further explanation is provided in a further feasible implementation of this embodiment, such as... Figure 4-5 As shown, the snap-fit ​​seat 411 includes an open-top C-shaped clamp 412 that matches the snap-fit ​​groove 423 and an arc-shaped connecting plate 413 that connects to the metal flexible hose 41. The snap-fit ​​groove 423 of the connecting pipe 422 is detachably snapped into the C-shaped clamp 412, ensuring a stable connection and facilitating assembly and disassembly. Furthermore, the inner wall of the C-shaped clamp 412 is covered with an anti-slip layer. In this embodiment, the anti-slip layer can be made of rubber to increase the connection stability between the dust collection head 42 and the connecting pipe 422.

[0029] In another further possible implementation of this embodiment, such as Figure 2 As shown, the width of the dust collection port 421 is not greater than the diameter of the connecting pipe 422, which can match the splashed wood chips of different materials and improve the wood chip collection efficiency.

[0030] In another further possible implementation of this embodiment, such as Figure 3 As shown, the width of the dust collection port 421 is greater than the diameter of the connecting pipe 422, which can match the splashed wood chips of different materials and improve the wood chip collection efficiency.
