It should be noted that the first spring 301d-5 pushes the oblique arm 301d-2, so that the included angle between the oblique arm 301d-2 and the partition 301h is increased, that is, the first spring 301d-5 tends to push the oblique arm 301d-2 away from the partition 301h, it should be noted that the outer side surface of the hook 301e is provided with the arc surface a, and the arc surface a corresponds to the corner position of the snap plate 303d, so that the snap plate 303d can be conveniently snapped into the hook 301 e.

Specifically, the pulling claw 301b is a lever structure formed by using the rotating shaft 301g as a fulcrum, in an initial state, one side of the inclined arm 301d-2 of the first spring 301d-5 is folded towards two sides, and in an extreme state, the circular boss 301d-4 is located in the side groove 202a-1, and at this time, the two hooks 301e are folded and are in a clamping state.

The pulling claw 301b further comprises an inner contraction arm 301f, and the inner contraction arm 301f is connected with the inclined arm 301d-2 at the round boss 301 d-4; the side wall of the push-pull groove 202a is provided with a side groove 202a-1, and a circular boss 301d-4 is arranged in the side groove 202 a-1; one end of the push-pull block 301a is connected with the bottom of the push-pull groove 202a through a second spring 202d, the end of the push-pull block 301a is provided with a contact rod 202e, and the contact rod 202e penetrates through the end of the first pipe groove 202c to be in contact with the outer side face of the cam 203 b.

Preferably, the push-pull block 301a is a cylindrical block, and the push-pull groove 202a is a cylindrical groove structure, it should be noted that the push-pull block 301a can rotate and rotate in the push-pull groove 202a, and since the pull claws 301b are embedded in the cut groove 301c and the side groove 202a-1, the push-pull block 301a is further limited so that it cannot rotate, but can only move along the length direction of the side groove 202a-1, i.e. the axial direction of the push-pull groove 202 a.

One end of the push-pull groove 202a is provided with a pressure groove 202f, one corner of the pressure groove 202f is arranged on a pressure contact point 202f-1, the outer side of the end part of the inner contraction arm 301f is provided with an inclined plane 301f-1, and the pressure contact point 202f-1 corresponds to the inclined plane 301f-1 in position; a second pipe groove 302b is formed in the outer cylinder 302, the second pipe groove 302b is communicated with the push-pull groove 202a, and the inner rod 303 is arranged in the second pipe groove 302 b; the second pipe groove 302b is provided with a limiting groove 302c, the inner rod 303 is provided with a ring plate 303b, the ring plate 303b is arranged in the limiting groove 302c, and the ring plate 303b is connected with one side of the limiting groove 302c through a third spring 303 c.

The second spring 202d is arranged to tend to pull the push-pull block 301a toward one end of the push-pull groove 202a, specifically, the push-pull block 301a is pulled toward the end near the end where the press groove 202f is arranged, so that the end of the inner contraction arm 301f is inserted into the press groove 202f, and further, the distance between the two inner contraction arms 301f is reduced, and the distance between the two hooks 301e is increased under the lever action.

In this embodiment, the operation principle of the whole device is that, in the initial state, the end of the feeler lever 202e contacts with the proximal arc surface 203c of the cam 203b, and at this time, under the action of the second spring 202d, the push-pull block 301a is pulled toward the end of the push-pull groove 202a, and in the process, the press contact point 202f-1 contacts the inclined surface 301f-1 and presses the inclined surface 301f-1, so that the distance between the two inner closing arms 301f is reduced, and the distance between the hooks 301e is increased.

When the device works, the driving motor 204 is started, the driving motor 204 drives the adjusting wheel 203 to rotate, in the process, the contact point of the end part of the feeler lever 202e and the cam 203b starts to move from the proximal cambered surface 203c to the distal cambered surface 203d, therefore, under the action of the cam 203b, the push-pull block 301a starts to move by overcoming the pulling force of the second spring 202d, the end part of the inner contraction arm 301f leaves the pressure groove 202f in the moving process, under the action of the first spring 301d-5, the distance between the inner contraction arms 301f is increased, and correspondingly, the distance between the clamping hooks 301e is decreased until the circular boss 301d-4 is positioned in the side groove 202a-1 to be limited to the utmost.

The push-pull block 301a continues to move until the arc surface a contacts the snap-gauge 303d, the hooks 301e are squeezed to both sides, and the snap-gauge 303d is squeezed between the hooks 301e and is clamped.

Then, the state is maintained, and the contact point of the end of the feeler lever 202e and the cam 203b starts to move from the circle center arc surface 203d to the approaching arc surface 203c, in the process, under the action of the second spring 202d, the push-pull block 301a and the catch plate 303d clamped by the catch 301e move together, namely, the inner lever 303 is pulled inwards, then the inwards retracted arm 301f is inserted into the pressing groove 202f, the catch plate 303d is released, under the action of the third spring 303c, the inner lever 303 is pulled back, and the arc block 303a strikes the pull rope 102a to generate vibration.
