[0002] A straight-cut circular saw is an industrial device used to perform cutting or slicing operations on a workpiece. It usually consists of a circular saw blade that moves along a straight path to achieve precise cuts. Circular saws are usually powered by an electric motor and can improve work efficiency and precision when processing materials such as metal, wood, plastic, etc. Straight-cut circular saws are widely used in industries such as manufacturing and construction.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 The utility model discloses a linear cutting electric circular saw, comprising an electric saw 1, and further comprising:

[0023] The measuring mechanism 2 includes a base 21 fixed on the protective shell of the electric saw 1, the inner wall of the base 21 is rotatably connected to a rotating seat 22 through a circular axis, a mounting seat 23 is fixed on the rotating seat 22, a laser pen 24 and a magnetic suction component 25 are arranged in the mounting seat 23, the magnetic suction component 25 is used to fix the laser pen 24, the laser line at the irradiation point of the laser pen 24 and the midpoint of the saw blade of the electric saw 1 are in the same vertical plane, and a clamping component 26 is arranged in the rotating seat 22, and the clamping component 26 is used to fix the rotating seat 22.

[0024] Specifically, the magnetic attraction component 25 includes a magnetic block 251 fixed in the mounting base 23, and a round block 252 movably connected in the mounting base 23 is fixed at the end of the laser pen 24. The round block 252 and the magnetic block 251 are magnetically attracted to each other, and the round block 252 is an iron block.

[0025] In this implementation, please refer to Figure 3 The laser pen 24 is connected to the magnetic block 251 by the magnetic force between the round block 252 and the magnetic block 251. When the laser pen 24 needs to replace the battery, the laser pen 24 can be directly pulled out, and then the battery of the laser pen 24 can be replaced, which makes the overall use more convenient.

[0026] Specifically, the edge of the end of the round block 252 is set as a curved surface, and the inner wall of the inlet of the mounting seat 23 is set as a curved surface.

[0027] In this implementation, please refer to Figure 3 After the two positions are both set with curved surfaces, when the laser pen 24 drives the round block 252 to be inserted into the mounting seat 23, the round block 252 can enter the mounting seat 23 more quickly through the guidance of the curved surface, and the insertion is easier.

[0028] Specifically, the clamping assembly 26 includes a slide groove 261 provided in the base 21, a clamping block 262 is movably connected in the slide groove 261, a spring 263 is fixedly connected between the bottom of the clamping block 262 and the slide groove 261, a clamping groove 264 is provided on the rotating seat 22, the clamping block 262 and the clamping groove 264 are meshed with each other, and a guide assembly 27 is provided on the clamping block 262.

[0029] In this implementation, please refer to Figure 3 After the block 262 is engaged in the slot 264, the rotating seat 22 can be fixed, but the rotating seat 22 will not be fixed. The rotating seat 22 can also be adjusted after a large external force is applied, which will not affect the use and is more convenient to use.

[0030] Specifically, the guide assembly 27 includes a guide groove 271 provided on the base 21 . The guide groove 271 is communicated with the slide groove 261 . A guide block 272 fixed on the clamping block 262 is movably connected in the guide groove 271 .

[0031] In this implementation, please refer to Figure 3 and Figure 4 The guide block 272 can only move vertically up and down, so the clamping block 262 can also only move vertically up and down, making the clamping block 262 more stable during use.

[0032] Specifically, the guide block 272 is T-shaped to improve the guiding accuracy.

[0033] In this implementation, please refer to Figure 4 When the T-shaped guide block 272 is in use, the surface area of ​​the guide block 272 is larger, and the area between the guide block 272 and the contact surface is larger, thereby avoiding the guide block 272 from moving in the horizontal direction and allowing the guide block 272 to move only in the vertical direction, thereby improving the guiding accuracy of the guide block 272.

[0034] Specifically, a limit block 3 is fixed on the rotating seat 22 to prevent the rotating seat 22 from rotating too much.

[0035] In this implementation, please refer to Figure 2 and Figure 3 The limit block 3 can limit the rotation range of the rotating seat 22, and the rotation range of the rotating seat 22 is the usable range of the laser pen 24. Through the limit of the limit block 3, it can be avoided that too much adjustment is required during the adjustment, and the reverse adjustment is required, which is more convenient to use.

[0036] The working principle and use process of the utility model are as follows: before cutting a long plate, a cutting line needs to be drawn on the plate, and then the laser pen 24 is inserted into the mounting seat 23, and the laser pen 24 is fixed by the magnetic force between the round block 252 and the magnetic block 251, and then the mounting seat 23 is rotated, and the mounting seat 23 will drive the rotating seat 22 to rotate, and the rotating seat 22 will rotate on the circular axis in the base 21, and when the rotating seat 22 rotates, the clamping block 262 will move downward, and the clamping block 262 will move from one of the clamping slots 264 to another clamping slot 264, and when the rotating seat 22 stops rotating, the spring 263 in the slide slot 261 will drive the clamping block 262 to be tightly clamped in the clamping slot 264, so as to fix the rotating seat 22, and when the clamping block 262 moves up and down, the clamping block 262 will drive the guide block 272 to move in the guide slot 271;

[0037] At this time, place the electric saw 1 in front of the plate to be cut, align the laser line emitted by the laser pen 24 with the drawn cutting line, and then the plate can be cut by the electric saw 1. During cutting, if the laser line deviates from the cutting line, it means that there is a deviation in the cutting, and it needs to be adjusted in time to improve the accuracy of cutting.

[0038] It should be noted that, in this article, terms such as "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of more restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.
