Chain saws are classified according to the same reason and source: the chain saw with four powers has obvious advantages and disadvantages.
Gasoline sawing: the mobility is strong, is fit for open-air portable work, but the noise is big, and it is troublesome to maintain, and the heat production is more.
An electric chain saw: power is stable, start up is fast, and is heavier than other saws, but the wire is inconvenient to move if it is too long.
A pneumatic chain saw: the air compressor is safe and pollution-free, has low noise and light weight, but is additionally provided with the air compressor, so that the occupied area is increased, and the air compressor is restricted by conditions.
A hydraulic chain saw: the power is sufficient, but the start is slower, the work is stable, the volume of the hydraulic pump station is smaller than that of the air compressor, and the cost is higher.
The scheme is mainly suitable for gasoline saws and electric chain saws. The existing chain saw lacks safety protection measures, when a worker works for a long time, the arm can generate a physiological reaction of acid and hemp under the influence of the vibration of the chain saw, when the worker stays in place, the palm can still grasp the handle of the chain saw, but the strength of the arm cannot normally support the whole weight of the chain saw. Therefore, the chain saw may be rotated and dropped around the palm-held portion, which may injure the body of the worker. In addition, when cutting a particular object, if the chain saw jumps violently, workers may be accidentally injured.
Therefore, there is a need to develop a chain saw that eliminates the potential safety hazard and can protect workers from injury.

Detailed Description
The invention is described in further detail below with reference to the following detailed description and accompanying drawings: as shown in fig. 1 to 5, a chain saw for avoiding potential safety hazards comprises a body 1 and a saw chain 3, wherein a starter is arranged in the body 1, the starter controls the operation of the chain saw, a holding part 2 is arranged on the body 1, the holding part 2 is provided with a starting switch 21, a cover plate 11 is arranged on the side surface of the body 1, a quarter-circle arc-shaped groove 4 is arranged at a part of the body 1 covered by the cover plate 11, one end of the arc-shaped groove 4 is located at the lowest point, the other end of the arc-shaped groove is located at a horizontal point, a circular truncated cone-shaped mounting part 41 is arranged at the end part of the lowest point of the arc-shaped groove 4, and an iron rolling; a guide arc 43 is arranged at the upper part of the installation part 41 of the arc-shaped groove 4, and the guide arc 43 plays a guide role when the rolling ball leaves the installation part; another tip of arc wall 4 is provided with scram portion 6, the movable sleeve is equipped with piston rod 72 in scram portion 6, the tip of piston rod 72 is provided with insulating baffle 7, the inside current conducting plate 71 that is provided with of baffle 7, current conducting plate 71 is provided with the salient the outside first end board 711 and second end board 712 of baffle 7, scram portion 6's both sides are provided with first connecting portion 61 and second connecting portion 62 respectively, first connecting portion 61 is provided with first conductive contact 611, second connecting portion 62 is provided with second conductive contact 621, first conductive contact 611 with second conductive contact 621 with the starter links to each other, the work of starter control chain saw.
The end face of the baffle 7 is provided with a pressure-bearing cushion pad 73.
The piston rod 72 is arcuate.
The cover plate 11 is uniformly provided with three bolts 13 and is fastened and installed on the body 1 by the bolts 13.
The side of the body 1 is further provided with an alarm part 12, the alarm part 12 is provided with a plurality of sound through holes, and the sound through holes are used for transmitting the alarm sound of the alarm part 12.
The installation department 41 with be provided with transitional action's inclined plane 44 between the arc wall 4, inclined plane 44 and horizontal line contained angle are 5 degrees.
The minimum distance from the connection position of the guide arc 43 and the arc-shaped groove 4 to the inclined plane 44 is larger than the diameter of the rolling ball 5.
The width of the arc-shaped groove 4 is not less than 1.3 times of the diameter of the rolling ball 5 and not more than 1.6 times of the diameter of the rolling ball 5.
And the included angle between the connecting line from the contact part of the rolling ball 5 and the mounting part 41 to the center of the rolling ball 5 and the vertical line is 40 degrees.
The outer side of the mounting part 41 is provided with a slope surface 42, and a rubber buffer 421 is arranged on the slope surface 42.
When the chain saw is turned over, if the saw chain 3 is higher than the body 1, the chain saw will not affect the operation and can still work normally. If the saw chain 3 is lower than the body 1, an accident may occur. If the angle is greater than 40 degrees, it is basically determined that the chain saw is not normally supported by the arm of the worker. An economic situation is now determined, requiring the chain saw to be shut down immediately, thereby minimizing injury.
When the turning angle is larger than 40 degrees, the mounting part can not support and limit the rolling ball 5, and the rolling ball 5 can be separated from the mounting part. If the turning angle continues to increase, the rolling ball 5 will continue to roll, eventually coming to the other end of the arc-shaped groove 4, touching and pressing the flap 7, so that the flap 7 moves. After the baffle 7 moves, the first plate 711 is pressed on the first conductive contact 611 finally, the second plate 712 is pressed on the second conductive contact 621, and therefore the circuit from the first conductive contact 611 to the second conductive contact 621 is connected, which means an accident, the starter stops working, and at this time, if the worker still presses the start switch 21, the chain saw still cannot start the cutting work, so as to avoid the accident. The alarm unit 12 of the present apparatus immediately sends an alarm to warn a worker.
When the device works normally, the rolling ball 5 is positioned on the mounting part, so that the starter works normally, and when a worker presses the starting switch 21, the chain saw can start cutting normally. However, if the ball 5 is separated from the mounting portion, the starter stops working, and at this time, if the worker still presses the start switch 21, the chain saw cannot start the cutting work, thereby preventing an accident.
The working indicator lamp 111 is arranged on the cover plate 11, and when the starter works normally, the working indicator lamp 111 can be lightened up to show that the starter can work normally at present.
The scope of the present invention includes, but is not limited to, the above embodiments, and the present invention is defined by the appended claims, and any alterations, modifications, and improvements that may occur to those skilled in the art are all within the scope of the present invention.
The invention has simple and reliable structure, convenient manufacture and low cost, has a safety protection structure and can avoid accidental injury of workers in use.
