Reconciliation of the ognosigs to the scraper of the slider 5 and the nut b is possible and can be used in the spring 7 with the washers 8 and 9. The nut is 6 signaling device devices. A screw off mechanism is known in which the screw rotates from a cusped pair. When the screw is in contact with the protrusion of the spring-loaded socket, the latter rotates around its axis and with the opposite end acts on the device that turns off the engine (warning device) ij. A disadvantage of the known mechanism is that the end of a two-armed lever sitting on an axis acts on the detector's indicator not at an axis, but at an angle, which leads to bending stresses on the brush and reduces the reliability of operation of the warning device. Also known is the control circuit of the drilling spindle with stops. When drilling, the pneumatic cylinder stem, which transmits the feed force to the spindle, moves progressively and with its abutment. interacting with the protrusion on-rod, moves it and turns off the system 2J. The disadvantage of this scheme is the absence of the return of the rod to its original position after the termination of the influence of the STI on the rod stop. The purpose of the invention is to increase the reliability of the device during reversible operation. . The goal is achieved by the fact that in the actuator of the detector, containing an input movable link, on which are placed control lugs, coupled with the protrusions of the slide mounted in the guide bodies with the possibility of reciprocating motion and rigidly connected with one of its protrusions the indicator, the slider is spring-loaded, the spring being installed between two slider shoulders, one of which is made adjustable, and its ends are connected to the restrictive stops of the housing through a freely installed the washers placed on the slider, placed by the slide with the housing body stops, FIG. 1 shows a detector, a general view; in fig. 2 is a view A of FIG. 1 (view of the movable link stops shifted relative to each other); FIG. 3 is a view B of FIG. 1 (Vits on slider ledges displaced relative to each other). The actuator of the detector (FIG. 1) consists of a removable body 1 having removable covers 2 and 3 and a bottom 4. Between it is designed to preload spring 7. The distance between center 4 and cover 3 is chosen structurally and determined by the height of spring 7. Protrusion 1O the slider is rigidly connected to the current 11 of the detector 12 mounted on the flange 13 of the removable body 1, and the other two protrusions 14 and 15 interact with the control stops 16 and 17 of the input moving link 18 displaced relative to each other. the casing of the block 19 signaling device a, the actuator of the detector works as follows, the Slider 5 and the trigger 11 of the detector 12 are in the middle position, while the spring 7 is decompressed, and the stops of the movable link 18 do not interact with the lugs of the slide 5, interacting with the protrusion 14 of the slider 5, moves it upward to a stroke of 3 mm to the extreme upper position. This movement is transmitted through the protrusion 10 of the slider 5 to the rod il of the detector 12, ensuring the rod travel 3 mm from the middle position to the extreme upper position (the pulls are extended). In this case, the nut 6 mounted on the slider 5, with its end through the washer 8 presses the spring 7 to the washer 9, -When the movable link 18 moves down, the spring 7 opens until the washer 8 rests on the bottom cover 3, while the slider and the rod 11 of the detector return to the middle position. Upon further downward movement of the linkage 18, the anvil 16 interacts with the protrusion 15 and moves the slider 5 downward to a stroke of 3 mm to the extreme lower position. The rod 11, respectively, moves by 3 mm of the extreme lower position (pulling rod). At the same time, the slider 5 with its shoulder through the washer 9 presses the spring 7 to the washer 8. Returning the slider to the middle position due to the installation of a return spring on it allows to increase the reliability in the reversing mode of the proposed actuator of the detector. In addition, the constructive execution of the drive signaling device with the installation of all parts in one case provides ease of operation.
