This is the prior art and will not be described in detail herein.

Example two:

the difference from the first embodiment is in the adjustment mechanism.

Referring to fig. 3-6, the adjustment mechanism includes a first connecting rod 31 and a second connecting rod 41 positioned within the cavity 12, sliding part 6 and locking piece, the one end that first connecting rod 31 passed bar hole 11 links to each other with first stopper 3, the other end is fixed to be provided with the third connecting rod 312 that can slide along the bottom wall in cavity 12, the one end that first connecting rod 31 was kept away from to third connecting rod 312 articulates there is first articulated pole 61, the one end that third connecting rod 312 was kept away from to first articulated pole 61 articulates on sliding part 6, the one end that second connecting rod 41 passed bar hole 11 links to each other with second stopper 4, the other end is fixed to be provided with the fourth connecting rod 412 that can slide along the bottom wall in cavity 12, the one end that second connecting rod 41 was kept away from to fourth connecting rod 412 articulates there is second articulated pole 62, the one end that fourth connecting rod 412 was kept away from to second articulated pole 62 articulates on sliding part 6.

The locking piece is positioned above the sliding piece 6 and matched with the lower part of the printing platform, the locking piece comprises a pair of locking blocks 7, a channel 71 for the sliding piece 6 to slide through is formed between the two locking blocks 7, the width dimension of the channel 71 is matched with the dimension of the sliding piece,

when moving first stopper 3, drive third connecting rod 312 through first connecting rod 31 and slide along the bottom wall in cavity 12, through the transmission of articulated first articulated rod 61 on third connecting rod 312, drive the vertical migration of sliding member 6 (sliding member 6 can only take place vertical migration under the locking piece effect), sliding member 6 drives fourth connecting rod 412 through second articulated rod 62 and slides along the bottom wall, and then drives second stopper 4 and removes, realizes the synchronous motion of first stopper 3 and second stopper 4.

It should be mentioned that the third connecting rod 312 and the fourth connecting rod 412 are symmetrically disposed on two sides of the sliding member 5. The distance between the sliding member 6 and the third connecting rod 312 is the same as the distance between the sliding member 6 and the fourth connecting rod 412, and the hinge point between the sliding member 6 and the first hinge rod 61 is the same as the hinge point between the sliding member 6 and the second hinge rod 62, so that the first limiting block 3 and the second limiting block 4 can realize mirror equidistant movement according to the sliding member 6.

A plurality of slots 72 are arranged on one surface of each locking block 7 facing the channel 71, the sliding piece 6 is provided with an inserting block 63 matched with the slots 72 in a clamping manner and an accommodating cavity 64 for accommodating the inserting block 63, and a telescopic spring 65 is arranged in the accommodating cavity 64 between the inserting block 63 and the sliding piece 6.

When the sliding piece 6 passes through the channel 71 formed between the two locking blocks 7, the inserting block 63 on the sliding piece 6 is accommodated in the accommodating cavity 64 under the action of abutting against the locking blocks 7, the telescopic spring 65 deforms and contracts, the locking blocks 7 move until being aligned with the slots 72 along with the continuous sliding movement of the sliding piece 6, the telescopic spring 65 recovers to deform to drive the inserting block 63 to stretch into the slots 72 from the accommodating cavity 64 to be clamped with the slots 72, and the gravity can be overcome to keep the sliding piece 6 locked.

Further, the insert 63 is a wedge shaped block having a tapered edge formed on an upper surface thereof. The upper wall of the slot 72 abuts the beveled edge of the insert 63.

When the first limiting block 3 and the second limiting block 4 apply guiding limiting force to the hard printing substrate made of metal, the hard printing substrate may also have reaction force to the first limiting block 3 and the second limiting block 4 on both sides, and the reaction force may cause the first connecting rod 31 and the second connecting rod 41 to move towards the direction away from each other, so as to cause the sliding member 6 to move downwards, therefore, a wedge block with a bevel edge formed on the upper surface is adopted as the insertion block 63, when the slider is about to move downwards under stress, the long edge of the wedge block may abut against the slot wall 72, so that the lateral force of the slot wall 72 of the slot wall to the wedge block is smaller, at this time, the wedge block may keep extending into the slot 72 under the action force of the extension spring 65, thereby preventing the sliding member 6 from moving downwards, and realizing the enhancement of the locking effect, but when the wedge block slides upwards on the sliding member 6, the bevel abuts against the slot wall 72, the wedge-shaped block is subjected to a reaction force of the groove wall in the vertical direction of the inclined surface, wherein the transverse force drives the wedge-shaped block to extrude the telescopic spring 65 and simultaneously move towards the accommodating cavity 64, so that the sliding part 6 moves upwards continuously.

In the technical solution of the first embodiment, both ends of the first connecting rod 31 and the second connecting rod 41 are in interference fit with the inner wall of the strip-shaped hole 11. Therefore, the reaction force of the first limiting block 3 and the second limiting block 4 on the two sides of the hard printing substrate pair is avoided, and the first connecting rod 31 and the second connecting rod 41 are driven to move towards the direction away from each other. However, in the long-term use process of the technical solution, the repeated movement of the first connecting rod 31 and the second connecting rod 41 will increase the abrasion between the first connecting rod and the inner wall of the strip-shaped hole 11, thereby causing the situation of being unable to be locked. And above-mentioned technical scheme has realized the better locking to first stopper 3 and second stopper 4.

Every locking block 7 moves with print platform's lower terminal surface level and smoothly respectively and is connected, is provided with magnet 9 and metal block 8 between two locking blocks 7, and magnet 9 and print platform's lower terminal surface fixed connection are provided with on every locking block 7 and are provided with the trace 81 of articulating mutually with metal block 8, are provided with the rope 82 that links to each other with sliding member 6 on the metal block 8.

Because the linkage rod 81 and the metal block 8 are hinged between the two locking blocks 7, the sliding block 6 is abutted against the metal block 8 in the process of gradually moving upwards, the metal block 8 moves upwards along with the sliding block 6, the linkage rod 81 drives the locking blocks 7 to slide away from each other, so that the channel 71 is gradually widened, as the metal block 8 moves upwards, the distance between the magnet 9 and the metal block 8 is reduced, the magnetic attraction force between the magnet 9 and the metal block 8 is gradually increased until the magnetic attraction force is larger than the gravity of the metal block 8, the metal block 8 is adsorbed on the magnet 9, at the moment, the two linkage rods 81 are parallel to each other (shown in figure 4), the linkage rod 81 keeps the width of the channel 71 between the locking blocks 7 unchanged after the channel is increased, at the moment, the insertion block 63 extending out of the accommodating cavity 64 is separated from the locking piece, the two locking blocks 7 lose the clamping force on the sliding block 6, and the sliding block 6 falls under the action of the gravity. With the downward movement of the sliding part 6, the rope 82 between the sliding part 6 and the metal block 8 is gradually tightened to pull the metal block 8 to be separated from the magnet 9 (i.e. the gravity of the sliding part 6 is greater than the magnetic attraction force between the metal block 8 and the magnet 9), the linkage rod 81 drives the two locking blocks 7 to approach each other, and the channel 71 recovers the initial width.

Further, a guide seat 14 for guiding the sliding direction of the sliding member 6 is arranged in the cavity 12, and the sliding member 6 is guided to vertically slide when being stressed, or the sliding member 6 is prevented from being stressed and deviated when being dropped by gravity.

Further, when the insert 63 stretches into a pair of slots 72 on the sliding member 6, the distance between the first stopper 3 and the second stopper 4 is the width of a common hard printing substrate, when the sliding member 6 moves until the insert 63 stretches into another pair of slots 72, the distance between the first stopper 3 and the second stopper 4 changes to the width of another common hard printing substrate, and so on, when the insert 63 stretches into each pair of slots 72, the distance between the first stopper 3 and the second stopper 4 represents the width of a common hard printing substrate.

The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention. It should be noted that modifications and embellishments within the scope of the invention may occur to those skilled in the art without departing from the principle of the invention, and are considered to be within the scope of the invention.
