The two third wires 34 are respectively fitted with the second guide wheels 37 on the output ends of the two groups of eighth spring telescopic members 36. The setting of the pulling component 3 allows the sliding plate 41 to be pulled out of the mounting shell 1 when the first motor 22 rotates. The setting of the eighth spring telescopic member 36 allows the third wire 34 to be always in a taut state and extends the length of the third wire 34 to prevent the movement of the mounting shell 1 from conflicting with the winding and release of the third wire 34.

[0052] Working principle: Pulling the first wire 53 drives the sliding block 51 to move, so that the abutting rod 43 moves, and the abutting rod 43 contacts the inclined surface of the limit block 445, so that the limit block 445 moves toward the first installation cavity 443, so that the inclined surface on the other side of the limit block 445 contacts the sliding plate 41, so that the second spring telescopic member 441 is released, driving the abutting member 442 to move, and the abutting member 442 contacts and squeezes the inclined surfaces of the two second limit members 4103, so that the two limit members move in opposite directions, driving the two second clamping plates 4102 to move, driving the two fifth spring telescopic members 4101 to contract, so that the sliding plate 41 can be pulled, and the sliding plate 41 is pulled by pulling the first wire 53 to slide until the stroke length of the sliding plate 41 inside the installation shell 1 is consistent with the interval length between each two punching positions, and then the first wire 53 is wound around the fixing member 52, and the first wire 53 is in a taut state through the thrust of the spring 12 on the sliding plate 41;

[0053] The two first clamping plates 112 are spread apart, and then the display stand bracket is positioned between the two first clamping plates 112, and then the two first clamping plates 112 are loosened, so that the two first clamping plates 112 clamp the display stand bracket, and before clamping, the drill bit 28 is aligned with the required drilling position, and before clamping, the mounting shell 1 is fitted with the display stand bracket;

[0054] Then, the first motor 22 is started to drive the threaded column 23 to rotate, so that the threaded sleeve 24 moves, the partition plate 25 moves, the connecting block 26 moves, the second motor 27 moves, and the drill bit 28 moves. At the same time, the second motor 27 is started to drive the drill bit 28 to rotate, so as to complete the drilling;

[0055] When the first motor 22 rotates, it drives the take-up drum 31 to rotate, so that the second wire 32 is wound up, and drives the rotating roller 33 to rotate, so that the two third wires 34 are wound up. The third wires 34 are always in a taut state through the extension and contraction of the telescopic rods of the eighth springs 12. When the two third wires 34 are wound up, the telescopic rods of the eighth springs 12 are compressed to the shortest position. After that, the two third wires 34 are continuously wound up, driving the sliding plate 41 to be pulled until its stroke length is completely located outside the mounting shell 1, and the spring 12 is compressed. At this time, the movement of the sliding plate 41 drives The two reset rods 46 slide, and at the same time, the sliding of the sliding plate 41 causes the first wire 53 to be in a relaxed state, so that the first spring telescopic member 42 is released, driving the abutment rod 43 to reset. The two reset rods 46 slide to drive the second spring telescopic member 441 to reset, and drive the abutment member 442 to reset, so that the limit block 445 is reset and engaged with the sliding plate 41 again. Due to the reset of the abutment member 442, the two fifth spring telescopic members 4101 are released, driving the two second clamping plates 4102 to move, so that the two second clamping plates 4102 clamp the display stand bracket;

[0056] Afterwards, when the drilling is completed, the first motor 22 is started to reverse, driving the second wire 32 to be released, so that the two third wires 34 are released, and the first motor 22 reverses to drive the drill bit 28 to reset, and drives the partition 25 to reset, and when the partition 25 is about to reset, it drives the clamping block 213 to move, so that the seventh spring telescopic member 212 moves, drives the sliding rod 29 to move, and moves the abutment block 210, and the abutment block 210 is pressed and contacted with the inclined surfaces of the two first limit members 113, so that the two first limit members 113 are away from each other. The two first clamping plates 112 are separated, and the two sixth spring expansion members 111 are contracted, so that the two first clamping plates 112 release the clamping of the display rack bracket, so that the spring 12 is released, and the installation shell 1 is driven to move, so that the punching assembly 2 moves, and the installation shell 1 is moved to store the sliding plate 41, so that the first wire 53 is in a tight state, so that the first spring expansion member 42 is compressed, and the contact rod 43 is driven to be pressed and contacted with the limit block 445, so that the two second clamping plates 4102 are released. The display stand bracket is clamped, and the damping block 49 is driven by the fourth spring expansion member 48 to squeeze the abutment member 442, so that the abutment member 442 moves slowly. At this time, the two limit posts 216 are driven to move in the two guide rails 215 under the movement of the clamping block 213. By tilting the two guide rails 215, the clamping block 213 is completely retracted into the slide groove 214 during movement, so that the seventh spring expansion member 212 contracts. When the clamping block 213 is completely retracted into the slide groove 214, the partition plate 25 no longer drives the clamping block 213 to move. 3, and the seventh spring expansion member 212 is released to drive the clamping block 213 to reset, so that the abutting block 210 is reset, and the two sixth spring expansion members 111 are reset, so that the two first clamping plates 112 clamp the display rack bracket, and then the abutting member 442 slowly moves to contact and squeeze with the two second limiting members 4103, so that the two second clamping plates 4102 release the clamping of the display rack bracket, so that the whole mechanism completes the displacement, and then reciprocating motion can quickly perform punching with the same interval.

[0057] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
