Description

Mini electric circular saw

Technical field

The utility model relates to the technical field of electric saws, in particular to a mini electric circular saw.

Background technique

The mini saw is an improvement to the electric circular saw. It is more compact and convenient to use than the traditional electric circular saw. The current mini saw usually includes a housing, a motor disposed in the housing, and a motor drive through the transmission mechanism. The saw blade, such a mini saw has no handle, and the housing itself acts as a handle. Since the motor is disposed in the housing, when the hand is held by the human hand, the vibration of the motor will be Directly transmitted to the human hand, resulting in the uncomfortable hand, easy to cause numbness in the hand for a long time, there are certain security risks.

Utility model content

The technical problem to be solved by the present invention is to provide a mini electric circular saw in order to solve the problem that the mini saw in the prior art has a housing with a motor inside as a handle for gripping.

The technical solution adopted by the utility model to solve the technical problem thereof is: a mini electric circular saw comprising a saw body and a saw blade, the saw body comprising a casing and a gear box at the front end of the casing, wherein the casing a motor is disposed, the saw blade is rotatably disposed on the gear box, and an output end of the motor is drivingly connected to the saw blade via a transmission component in the gear box, and the saw body is provided with a handle, and when the handle pushes the circular saw When the cutting feed is performed, the thrust of the handle against the body of the saw body acts on the lower side of the body of the saw body.

In this solution, the body of the saw body with the motor is separately designed from the handle, and the handle is directly held by the hand during use, thereby avoiding the vibration of the motor being directly transmitted to the hand, thereby improving the grip comfort of the mini electric circular saw. At the same time, during cutting, the circular saw can be directly pushed through the cutting direction of the saw blade to facilitate the force application.

Specifically, the axial direction of the motor is disposed to intersect the axial direction of the saw blade.

The position of the handle on the body of the saw body can preferably be the following three categories:

In the first type, the handle is disposed on the housing, and the connection between the handle and the housing is located at a lower intermediate portion of the peripheral wall of the housing.

In the second type, the handle is disposed on the housing, and a part of the connection between the handle and the housing is located at a lower side of the peripheral wall of the rear end of the housing, and another portion is located at an end surface of the rear end of the housing.

In the third category, the handle is disposed on a gearbox, and the connection of the handle and the gearbox is located on a lower side of the gearbox.

The utility model has the beneficial effects that the mini electric circular saw of the utility model is designed separately from the handle body with the motor inside, and the hand can directly hold the handle when used, thereby avoiding the vibration of the motor being directly transmitted to the hand. The gripping comfort of the mini electric circular saw is improved, and the handle is located on the lower side of the saw body, which facilitates the cutting feed force to the circular saw through the handle, and is small in size.

Detailed ways

The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, only to illustrate the basic structure of the present invention in a schematic manner, and thus only show the configurations, directions and references (for example, up, down, left, right, etc.) related to the present invention. It may be used merely to assist in the description of the features in the figures. The scope of the claimed subject matter is therefore not to be construed in a

Example 1

As shown in FIG. 1-4, a mini electric circular saw includes a saw body and a saw blade 2. The saw body includes a housing 1 and a gear box 5 at a front end of the housing 1. The housing 1 is provided with a motor. The saw blade 2 is rotatably disposed on the gear box 5, and the axial direction of the motor intersects with the axial direction of the saw blade 2. The output end of the motor is connected to the saw blade 2 via a transmission component in the gear box 5, and the saw body is provided with The handle 3, when the handle 3 pushes the circular saw cutting feed, the thrust of the handle 3 against the body of the saw body acts on the lower side of the body of the saw body.

The handle 3 is disposed on the housing 1, and the connection of the handle 3 and the housing 1 is located at a lower intermediate portion of the peripheral wall of the housing 1.

The front end of the gear box 5 is provided with a bottom plate 4, and the bottom plate 4 is fixed with a depth plate 6 through which the arcuate groove 6-1 is inserted, and the arcuate groove 6-1 is provided with a locking screw 7 and a locking screw 7 It is screwed to the gear box 5, and the locking screw 7 is loosened to adjust the inclination angle of the bottom plate 4. After the adjustment, the locking screw 7 can be directly tightened.

A lock button 8 is disposed on an outer side of the handle 3 near the outer end of the housing 1. The switch 8 is disposed on a side of the handle 3 adjacent to the bottom plate 4, and the switch button 9 is located at an end of the handle 3 adjacent to the housing 1, the lock button 8 and The position of the switch button 9 can facilitate the touch of the hand. In use, the tight lock button 8 is opened in advance, and when the switch button 9 is pressed, the mini circular saw can be started.

Both the saw blade 2 and the handle 3 are located on the same side of the housing 1, i.e. the axis of the saw blade 2 is offset to be below the axis of the motor.

The mini electric circular saw in this embodiment changes the design concept of the traditional mini electric saw, and the housing 1 with the motor inside is separately designed from the handle 3. When in use, the handle 3 is directly held by the hand, thereby avoiding the motor. The vibration is transmitted directly to the hand, which improves the grip comfort of the mini electric circular saw, while the handle 3 is located on the lower side of the body of the saw body, so that the cutting feed force can be applied to the circular saw through the handle 3.
