状態に保ち得るように構成されている。Prior Art In order to ensure safety, the above-mentioned working machines require the operator to correctly grasp the handle with both hands, and if one hand leaves the handle, the machine becomes unstable. There is a danger that operating tools such as rotary cutting blades may come into contact with workers and cause harm. However, the conventional throttle control device is constructed such that even when the handle is held with one hand, the throttle lever is kept in the drive position and the machine can be kept in the drive state.

解決するためになされたものである。Problems to be Solved by the Invention Conventional devices such as those described above do not allow the operator to accidentally remove one hand from the handle due to a shock that occurs when, for example, a working tool of a machine hits a surrounding hard object during work. However, the problem is that if the throttle lever is held, the machine is still in operation, making it extremely unsafe. The present invention has been made to solve these problems.

である。Means for Solving the Problems Therefore, the present invention provides a throttle control device for a working machine that uses an internal combustion engine as a power source and is operated by gripping the handle with both hands. A large link operatively connected to the throttle valve of the engine, a spring biasing the large link toward the idling position of the throttle valve, and a spring having one end coaxially pivoted to an intermediate portion of the large link and extending in opposite directions to each other. , and two small links capable of independently pivoting on a plane substantially parallel to the pivot plane of the large link, each connected to these two small links so that each small link is biased by the large link. A pair of springs each biased in the same direction, and a stopper portion that engages one small link to restrict the pivoting when the other small link pivots against the biased pressure of the spring. and a pair of cables respectively connecting each small link and a left-hand operation lever and a right-hand operation lever provided on the handle so that each small link can pivot against the action of a spring. It is characterized by:

把持されて両方の操作レバーが操作されたとき、
二つの小リンクが共に枢動して大リンクをばねの
作用に抗して枢動させ、このためスロツトル弁は
開いて機関を加速する。Effect Therefore, with the above configuration, when only one operating lever of the handle is operated, the small link connected to it pivots, but the other operating lever does not pivot, so the large link is biased by its spring. The throttle valve remains in the idle position and does not pivot. When the handle is gripped correctly and both control levers are operated,
The two small links pivot together to cause the large link to pivot against the action of the spring, which opens the throttle valve and accelerates the engine.

刃へ伝達し刈刃をを駆動する。 The illustrated embodiment is a device suitable for, for example, a portable power pruning machine, in which a box-shaped frame 1 is fixed to a part of the machine body, and one end of a large link 2 is connected inside the frame 1 by a pin 3. It is pivotably supported. The other or free end of the large link 2 is connected via a cable 4 to a throttle valve of a carburetor of an internal combustion engine.
Further, the large link 2 has one end of a tension coil spring 5 attached near its free end, and the other end of the spring 5 is locked to a pin 6 implanted in the frame 1. The spring 5 biases the large link 2 around the pin 3 in a clockwise direction as viewed in FIG. Therefore, it is held in the position shown, in which the throttle valve of the carburetor of the internal combustion engine is in the idling position to keep the engine idling, and the centrifugal clutch is not activated, stopping the drive of the cutting blade. . When the large link 2 is pivoted counterclockwise from the position shown against the action of the spring 5, the carburetor throttle valve opens to accelerate the engine and the centrifugal clutch operates to harvest the power. It is transmitted to the blade and drives the cutting blade.

周りに反時計方向へ偏圧されている。 A pin 8 is implanted on the outer surface of the intermediate portion of both longitudinal ends of the large link 2, and two small links 9 and 10 are coaxially pivoted to the pin 8 at one end of each. Each small link 9, 10 has pin 8
The large link 2 can pivot independently on two planes extending in opposite directions from the main link 2 and substantially parallel to the pivot plane of the large link 2. One of the small links 9 has a pair of stopper parts 11 and 12 integrally formed on both sides of the end adjacent to the other small link 10, and the stoppers 11 and 12 are arranged so that the small links 9 and 10 are relative to each other. When pivoting, it engages with the other small link 10 to limit the relative pivoting of the two small links 9, 10 to a predetermined angular range between the stoppers 11 and 12. One small link 9 has one end of a tension coil spring 13 attached to its free end, and the other end of the spring 13 is locked to a pin 14 implanted in the frame 1. For this reason,
Spring 13 biases one small link 9 clockwise around pin 8. The other small link 10 is biased counterclockwise around the pin 8 by a tension coil spring 16 stretched between its free end and a pin 15 implanted in the frame 1.

る。 In use, first grasp the handle with the left hand and operate only the left hand control lever to pivot the other small link 10 clockwise against the action of the spring 16 to the position shown in FIG. At this time, the other small link 1
0 is the upper stopper part 12 of one small link 9
However, the large link 2 is in the rest position shown, the engine is idling, and the cutting blade is not being driven. Next, when you grip the handle with your right hand and operate the right-hand control lever to pull the cable 17, both small links 9 and 10 are pulled up together, and the large link 2 is pivoted counterclockwise around the pin 3. make it move. For this purpose, the cable 4 is pulled upwards, increasing the opening of the carburetor throttle valve, accelerating the engine and actuating the centrifugal clutch to drive the cutting blades. In this state, for example, if the operator's right hand suddenly moves away from the right-hand handle, one of the small links 9 and large links 2 will immediately return to the position shown in Fig. 1 by the action of the springs 13 and 5, and the cutting blade will Stop the drive to minimize the risk of harm to workers, etc. Conversely, when the operator releases his left hand from the left hand handle, the other small link 10 is activated by the spring 1.
6, the large link 2 pivots counterclockwise about the pin 8 as a fulcrum, and at the same time, the large link 2 returns to the position shown in FIG. 1 due to the action of the spring 5, stopping the driving of the cutting blade.

する。Effects of the invention With the configuration of the invention explained above, the engine can be accelerated only when the operator is correctly grasping the handle with both hands, and when one hand leaves the handle, the engine can be operated with that hand. The operating lever is released and the tension on the cable connected to it is removed, so that the small link connected to this cable returns under the action of its spring, and at the same time the large link also returns under the action of its spring, immediately starting the engine. It is possible to prevent accidents that could cause harm to workers due to idling, and since the structure of the device is simple and consists only of mechanical mechanisms, it can be applied to various types of working machines used outdoors. It has the following effects.
