Problems solved by technology
[0003] However, if the fuselage and the bottom plate are connected by guide rails, usually due to the large sliding friction force and the influence of dust, in order to ensure the effective ejection of the shield, the spring force is usually large, and the initial cutting is very difficult.
If the fuselage and the bottom plate are connected by a rotating shaft, it will also be difficult to press down, and the rotation angle of the fuselage is too large, which makes it inconvenient to apply force

Embodiment Construction
[0025] Please refer to figure 1 , figure 2 and image 3 , just for the convenience of description, here we define figure 1 , figure 2 and image 3 Below is the front of the portable cutting machine 100, and above is the rear of the portable cutting machine 100. The portable cutting machine 100 includes a fuselage 110, a base plate 130, and a grip 150; the fuselage 110 is connected to the base 130, and the relative positions of the two can change; the grip 150 is arranged on the fuselage 110 for The operator holds it. In this embodiment, the grip part 150 is a handle arranged at the rear of the fuselage 110. These handles include straight handles, D-shaped or arc handles, etc. Of course, the grip part 150 can be used with the machine body. The body 110 is integrally formed. The body 110 includes a casing 111 , a drive assembly (not shown in the figure), and a saw blade 112 . The driving assembly includes a motor and a reduction box, and the driving assembly can be acco...

The invention relates to a portable cutting machine. The portable cutting machine comprises a base plate, a machine body, a holding part, a first connecting rod and a second connecting rod, wherein the machine body can move relative to the base plate, and the holding part is arranged on the machine body. The machine body comprises a driving assembly and a saw blade, and the driving assembly is used for driving the saw blade to rotate. The first end of the first connecting rod is rotatably connected with the machine body through a first rotary shaft, and the second end of the first connecting rod is rotatably connected with the base plate through a second rotary shaft. The first end of the second connecting rod is rotatably connected with the machine body through a third rotary shaft, and the second end of the second connecting rod is rotatably connected with the base plate through a fourth rotary shaft. According to the portable cutting machine, a four-connecting-rod structure is formed by the first connecting rod, the second connecting rod, the connecting line of the axis of the first rotary shaft and the axis of the third rotary shaft, and the connecting line of the axis of the second rotary shaft and the axis of the fourth rotary shaft; and when the machine body is pressed through the four-connecting-rod structure, initial cutting operation of the portable cutting machine is smooth, force can be applied conveniently, and cutting is easy.
Description
technical field [0001] The invention relates to a power tool, in particular to a portable cutting machine. Background technique [0002] A traditional portable cutting machine, such as a portable electric circular saw, usually includes a base plate and a body. The body includes a saw blade and a drive assembly, and the drive assembly drives the saw blade to rotate. During the cutting process, the cutting action is realized by changing the relative positions of the bottom plate and the fuselage. Generally, the fuselage and the bottom plate are connected by a guide rail or a rotating shaft. [0003] However, if the fuselage and the bottom plate are connected by guide rails, usually due to the large sliding friction force and the influence of dust, in order to ensure the effective ejection of the shield, the spring force is usually large, and the initial cutting is very difficult. If the fuselage and the bottom plate are connected by a rotating shaft, it will also be difficul...
