the bottom of the rotating shaft 4 is connected with an output shaft of the motor 3, in other embodiments, the rotating shaft 4 and the output shaft of the motor 3 can be integrally designed, when the motor 3 works, the output shaft drives the rotating shaft 4 to rotate, the top of the rotating shaft 4 extends out of the base 1, and a groove 5 is formed in the left side wall of the rotating shaft 4;
the right end of the limiting elastic part 6 is fixedly arranged in the groove 5, the right end of the limiting elastic part is fixedly connected with the bottom of the groove 5, when the limiting elastic part 6 is stressed, the limiting elastic part can contract towards the right side, and when the extrusion force is released, the limiting elastic part 6 can automatically recover the original position due to self resilience force, so that the limiting rod 7 connected with the limiting elastic part is limited;
the right end of the limiting rod 7 is fixedly connected with the left end of the limiting elastic part 6, the front side of the limiting rod 7 is an extrusion side (the extrusion side is the side where the limiting rod 7 and the limiting groove 11 are likely to interact, for example, when the take-up reel 8 rotates clockwise, and the rotating shaft 4 is not moved, the side of the limiting rod 7 departing from the rotating direction of the take-up reel 8 is extruded by the limiting groove 11, the side of the limiting rod 7 departing from the rotating direction of the take-up reel 8 is the extrusion side, when the rotating shaft 4 drives the take-up reel 8 to rotate anticlockwise, the extrusion side of the limiting rod 7 tries force on the limiting groove 11, so as to drive the take-up reel 8 to rotate anticlockwise, the intersection of the left end and the front side of the limiting rod 7 is set to be an inclined plane 71, and the inclined plane 71 is gradually inclined backwards along the left side direction;
the take-up reel 8 is positioned on the upper side of the base 1 and is arranged outside the rotating shaft 4, a through hole 10 matched with the rotating shaft 4 is formed in the take-up reel 8, when external force is received, the take-up reel 8 can rotate around the rotating shaft 4, a limiting groove 11 matched with the limiting rod 7 is formed in the inner wall of the through hole 10, when the limiting elastic part 6 is in a natural state, one part of the left side of the limiting rod 7 is positioned in the limiting groove 11, and one part of the inclined surface 71 is positioned outside the limiting groove 11; when 8 clockwise turning of take-up reel, through-hole (10) inner wall and spacing groove (11) preceding lateral wall intersection can extrude inclined plane 71, because inclined plane 71 inclines backward along the left side direction gradually, extrudees the in-process at 11 pairs of inclined planes 71 at the spacing groove, can produce the partial pressure of a dextrad to gag lever post 7, and elasticity spacing piece 6 receives the compression, and gag lever post 7 leaves the spacing groove.
The working principle of the device is as follows:
because take-up reel 8 alone or with pivot 4 rotation in the receive and release line process, for more visual description, the stress analysis takes recess 5 to be located the pivot 4 left side as the example.
And (3) paying off: draw the line of bullet from the inside of take- up reel 8, 8 clockwise rotations of take-up reel this moment, pivot 4 does not rotate, and take-up reel 8 is rotating the in-process, if gag lever post 7 left side has a part to be located the spacing groove 11, through-hole 10 inner wall can extrude the inclined plane 71 of the junction of gag lever post 7 left side and front side from the place ahead with 11 preceding lateral wall intersections of spacing groove, because inclined plane 71 inclines backward gradually along the left side direction, can produce the partial pressure of a dextrad to gag lever post 7 in 11 extrusion processes to inclined plane 71 at the spacing groove, and elasticity spacing piece 6 receives the compression, and gag lever post 7 leaves the spacing groove, carries out normal unwrapping wire.
A wire take-up process: starting the motor 3, driving the rotating shaft 4 to rotate anticlockwise through the motor 3, driving the limiting rod 7 to rotate by the rotating shaft 4, and enabling the limiting rod 7 to be inserted into the limiting groove 11 again under the action of centrifugal force and resilience force of the elastic limiting sheet 6 in the rotating process, wherein the limiting rod 7 can extrude the limiting groove 11 at the intersection of the inner wall of the through hole 10 and the front side wall of the limiting groove 11, and at the moment, although the limiting groove 11 can generate reaction force on the limiting rod 7, the reaction force also has right partial pressure; but gag lever post 7 still receives two leftward effort simultaneously, and is first, because gag lever post 7 is following pivot 4 rotates, rotates and can produce a leftward centrifugal force to gag lever post 7, and the second, elasticity spacing piece 6 can produce a leftward resilience force to gag lever post 7 when receiving the extrusion, and centrifugal force and the 6 resilience force combined action of elasticity spacing piece can offset like this spacing groove 11 is right the partial pressure effect of the dextral of gag lever post 7, gag lever post 7 can continue to keep the inserted state to spacing groove 11, and then drives 8 anticlockwise rotations of take-up reel, accomplish and receive the line.
In summary, during paying off, the take-up reel 8 rotates clockwise, and since the inclined surface 71 is arranged at the intersection of one end of the limiting rod 7 and the extrusion side, under the condition that the rotating shaft 4 is not moved, the limiting groove 11 can push the limiting rod 7 to compress the limiting elastic part 6 and enable the limiting rod 7 to leave the limiting groove 11, so that normal paying off can be performed; when the unwrapping wire finishes and needs to receive the line, starter motor 3 drives pivot 4 through motor 3 and rotates, and pivot 4 drives gag lever post 7 and rotates, makes gag lever post 7 rotate the in-process, under the combined action of rotation centrifugal force and the spacing piece of elasticity 6 resilience force, inserts the inside of spacing groove 11 again, and then drives take-up reel 8 anticlockwise rotation to reach the effect of receiving the line fast.
In this embodiment, the elastic limiting sheet 6 is a spring, and in other embodiments, other elements that are compressed and contracted and have resilience, such as an elastic rubber pad, may also be used.
