Description

Technical Field

[0001] The utility model relates to a handheld slotting machine which can cut through a wall. Background Art

[0002] At present, in the process of office and home interior decoration, circuit wiring, water and gas pipeline laying, television and communication line wiring, etc., handheld electric slotting machines are generally used to slot on the ground or wall. Due to the high slotting efficiency of handheld electric slotting machines, they are very popular among users. However, for work that requires cutting through walls, existing slotting machines are not suitable, because existing slotting machines all have a fixed protective cover to determine the cutting depth. This type of slotting machine can only be used for cutting wire grooves. If it is necessary to cut through the wall, other tools need to be replaced. Therefore, designing a slotting machine with a protective cover and the ability to cut through the wall will bring a lot of convenience to the decoration work. Utility Model Content

[0003] The utility model mainly solves the technical problems existing in the prior art, thereby providing a handheld slotting machine which has a simple structure and a wide application range and can cut through walls.

[0004] The purpose of the utility model can be achieved through the following technical solutions:

[0005] A handheld slotting machine capable of cutting through a wall comprises a machine body, a main handle arranged at the rear end of the machine body, a protective baffle arranged on the machine body, a secondary handle arranged on the protective baffle, a protective bottom plate arranged at the bottom of the protective baffle, a baffle mounting seat arranged at the front end of the machine body, a saw blade arranged at the front end of the machine body and connected to a motor through a transmission belt, saw blade baffles arranged at both ends of the baffle mounting seat, a protective cover arranged in front of the protective baffle, and two rollers arranged at the front end of the protective cover.

[0006] Preferably, the saw blade shield and the shield mounting seat are both arc-shaped, the saw blade shield and the shield mounting seat are rotatably connected, and a torsion spring is provided at the connection between the saw blade shield and the shield mounting seat to reset the saw blade shield.

[0007] Preferably, one end of the protective cover is rotatably connected to the protective base plate located below the fuselage, the protective cover is tilted forward, the roller arranged at the other end of the protective cover is located above the saw blade, and a torsion spring is arranged at the connection between the protective cover and the protective base plate to reset the protective cover.

[0008] Preferably, the saw blades are two superimposed arrangements.

[0009] Preferably, the rotation of the saw blade shield allows the saw blade to cut beyond the radius.

[0010] Preferably, the auxiliary handle is arranged at the rear of the protective baffle, and the protective bottom plate is arranged forward at the bottom of the protective baffle.

[0011] The beneficial effects of the handheld slotting machine that can cut through walls of the utility model are as follows: since the rotation of the saw blade shield of the handheld slotting machine that can cut through walls allows the saw blade to cut beyond the radius, the saw blade can cut through the wall to a greater depth; the protective cover can be rotatably arranged, which not only plays a protective role, but also can rotate according to the deepening of the cutting without affecting the cutting work; the rotating wheel arranged at one end of the protective cover prevents the protective cover from scratching the wall when it is against the wall, making the rotation of the protective cover more convenient; the arrangement of the protective baffle and the protective bottom plate can well block the dust generated during cutting, and will not affect manual operation.

[0016] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0017] like Figure 1 to Figure 2 As shown, the utility model adopts the following technical scheme: a handheld slotting machine capable of cutting through a wall, comprising a body 2, a main handle 1 arranged at the rear end of the body 2, a protective baffle 4 arranged on the body 2, a secondary handle 3 arranged on the protective baffle 4, a protective bottom plate 5 arranged at the bottom of the protective baffle 4, a baffle mounting seat 10 arranged at the front end of the body 2, a saw blade 6 arranged at the front end of the body 2 and connected to the motor through a transmission belt, a saw blade baffle 9 arranged at both ends of the baffle mounting seat 10, a protective cover 7 arranged in front of the protective baffle 4, and two rollers 8 arranged at the front end of the protective cover 7.

[0018] The saw blade shield 9 and the shield mounting seat 10 are both arc-shaped, and the saw blade shield 9 and the shield mounting seat 10 are rotatably connected. A torsion spring (not shown) is provided at the connection between the saw blade shield 9 and the shield mounting seat 10 to reset the saw blade shield 9.

[0019] One end of the protective cover 7 is rotatably connected to the protective base plate 5 and is located below the fuselage 2. The protective cover 7 is tilted forward. A roller 8 arranged at the other end of the protective cover 7 is located above the saw blade 6. A torsion spring is arranged at the connection between the protective cover 7 and the protective base plate 5 to reset the protective cover 7.

[0020] The saw blades 6 are arranged in two overlapping configurations.

[0021] The rotation of the saw blade shield 9 can allow the saw blade 6 to perform cutting beyond the radius.

[0022] The auxiliary handle 3 is arranged at the rear of the protective baffle 4 , and the protective bottom plate 5 is arranged at the bottom of the protective baffle 4 facing forward.

[0023] The worker holds the main handle 1 with one hand and pushes the auxiliary handle 3 forward with the other hand. The saw blade 6 rotates driven by the transmission belt. During cutting, as the cutting depth increases, the saw blade shield 9 and the protective cover 7 will be against the wall. The roller 8 at one end of the protective cover 7 will rotate after being against the wall, which will not cause damage to the wall. At the same time, it can better allow the protective cover 7 to rotate. The saw blade shield 8 will also rotate with the connection as the axis after being against the wall. The rotation of the saw blade shield 8 can allow the saw blade 6 to exceed the radius for cutting, so that the saw blade 6 can penetrate the wall to a greater depth. After cutting is completed, the saw blade shield 9 and the protective cover 7 will be reset under the action of the torsion spring at the connection. The main handle 1 and the auxiliary handle 3 are both located behind the protective baffle 4. The protective bottom plate 5 located at the bottom of the protective baffle 4 is set forward, which can well block the dust generated during cutting and will not affect manual operation.

[0024] The beneficial effects of the handheld slotting machine that can cut through walls of the utility model are as follows: since the rotation of the saw blade shield of the handheld slotting machine that can cut through walls allows the saw blade to cut beyond the radius, the saw blade can cut through the wall to a greater depth; the protective cover can be rotatably arranged, which not only plays a protective role, but also can rotate according to the deepening of the cutting without affecting the cutting work; the rotating wheel arranged at one end of the protective cover prevents the protective cover from scratching the wall when it is against the wall, making the rotation of the protective cover more convenient; the arrangement of the protective baffle and the protective bottom plate can well block the dust generated during cutting, and will not affect manual operation.

[0025] It should be understood that in the claims and description of the utility model, all "including..." should be understood as an open-ended meaning, that is, its meaning is equivalent to "at least contains...", and should not be understood as a closed meaning, that is, its meaning should not be understood as "only includes...".

[0026] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
