Description of the invention (3) As further shown in Fig. 2 and Fig. 3, the triangular piece 8 is composed of two plates that are parallel to each other and mirror-symmetrical, and the pawl lever 10 is housed therebetween and fixed on the shaft 9 The shaft is fixedly connected to the board. The third corner of the triangular piece 8 is connected to each other by a pin i 2 which can contact the pawl lever 10 to restrict the movement of the triangular piece 8. As already mentioned, for consideration of symmetry, the triangular piece 8 and the detent lever 10 therebetween are provided with a toggle joint plate 6 on each side, and the toggle joint plates are connected to each other by a shaft 7. The transmission lever 3 partially shown in FIG. 2 is composed of two plates that extend on the plane 15 of the two sides of the actuator housing and are fixed to the side plate 1 5 of the actuator housing with the lower part shown in FIG. 4. The depressions 1 on 4. In the present embodiment, the transmission lever 13 is composed of a single U-shaped bent plate, and a connecting portion thereof is provided with a bolt 16 and an operating handle 7 extending from the transmission housing. It is assumed that between the elbow joint bolt of the shaft 7 and the bolt 16 of the transmission rod 13, a transmission bullet η 1 8 is provided on each side of the triangular piece 8. The peripheral plate 15 and the lower part 1 3 a of the transmission rod 13 are also provided on both sides of the triangular piece. The trip device in Figure 1 is labeled 19. This trip device controls the trip of the pawl lever 10 in a conventional manner. The working position shown in FIGS. 1 to 4 is ⑽, and the operating handle 17 is in a left-inclined position, so that the force acting line of the spring 18 is to the left of the vehicle 9. Since the pawl lever 10 is engaged with the tripping device 19 when in the working position On, the spring force acting through the triangular piece 8 and the shaft 9 »cannot perform a counterclockwise upward movement, so the K force is rebounded. The corner piece 8 is caused to rotate clockwise around the shaft 9. Therefore, the shaft γ is forced to pass through the connecting line of the shafts 9 and 4, which causes the toggle joint plate 6 to act on the control rod 3 in the contact direction of the movable contact rod when the pawl rod 10 is engaged as described above.

Description of the invention (4) Figure 5 shows the trip position. When the ratcheting engine enters this operating position, when the claw is tripped by the tripping device 19, it is lowered to the position shown in FIG. In the working position, the operating handle 17 acts on the shaft in this position ;: Γ 箬 and the elbow joint plate 6 are rotated by the shaft 3, so that γ ^ i 〃 is pulled upward, which causes the control section to pass the movable contact lever 1 Separation. Welding that may occur during work will force separation. Fig. 6 shows that the dry contact buckle 1 cannot reach the spring 18 early. In this state, it can be seen from the method that the contact rod is separated. The first I :: 3 set: the true working state of the broken contact rod 1, and the two special designs will be described below. Posts m μ are provided on one or both sides of the rod housing 15. Kind of motion # Just as the satellite axis 5 of the control lever 3 is pivoted, the other end of the stem is === fixed on the side plate 15 and embedded in the stopper = lever two = middle length is provided: a protrusion 23, which can be driven into a driving helmet If you cannot enter the position, you can make the operating handle 1 7 # ,, as follows, as the final working position 01 ^ where the contact rod 1 is correctly separated. For: First: !! The needle pushes the operating handle 17 until the notch 24 and the protrusion 23 fit the handle 17 operating handle Π, then the thrust is directly transmitted by the operator ^ 吝: transmitted to the stop lever 20, so via the shaft 5 pairs Control: Small clockwise torque. Because the distance between the shaft 2 and the shaft 5 is very small, the handle 17 can obviously feel the resistance caused by the jointing operation. At this point, when the operator attempts to shut down the engine, "Mx sees the known handle" [7 cannot enter the closed position 0FF. If the contact lever 1 is not welded, the stop lever 2 is in the position shown in Fig. 5, which makes the case No. 88115fi4fi_V. Description of the invention (5) Set the operating handle 1 7 and the transmission rod 1 to 0 FF. In this way, push the pawl rod i 3 in the direction of the transmission rod j 3 to the closing position. The engine is provided with a | Via a transmission spring 18 =:;: 17; "transmission rod 13 ', this transmission makes the control of the operating contact rod 丨 3.2, σ, 7, δ, the elbow joint is effectively connected to 10. The engine is also provided with 22,2, a current-released pawl lever lever 20, and the stop lever is in a stop-close position that interacts with ^ 3 when the contact lever is locked. The method is to make the stop ^ ， As the handle 1 7 cannot enter the rotation and automatically enter the stop transmission lever: When the contact lever contacts, the position is briefly explained by the symbol of the control lever 3 element. year
