[0015] A method for using a device and method for engraving artworks, comprising the following steps:

[0016] S1. Place the raw material to be clamped and engraved on the rotating clamping plate, start the three-point bevel gear set to drive the three three-claw clamps distributed in a ring to push inward and clamp the material, start the clamping adjustment cylinder to push the clamping sliding block to pull the clamping installation column through the clamping connecting arms on both sides, the clamping installation column gathers inward along the clamping sliding groove and clamps the material through the arc-shaped clamp connected to the clamp connecting arm. The bottom clamp connecting arm is fixed at a constant height, and the top is adjusted by the height adjustment cylinder to clamp raw materials of different heights.

[0017] S2. The laser installation mechanism is connected to the path switching mechanism through a mobile connecting seat and a mounting sliding seat to control the moving path. The position and angle of the laser engraving head are adjusted through the longitudinal adjustment arm, the angle adjustment disk and the universal adjustment arm, and the clamped material is laser engraved. When the laser installation mechanism moves horizontally, the follow-up steering mechanism is controlled by the path switching mechanism and does not work for plane engraving. When the laser installation mechanism rotates in a circle, the follow-up steering mechanism is controlled by the path switching mechanism so that the laser installation mechanism drives the active rotating seat to rotate. The active rotating seat is connected to the rotating clamping disk through a reverse connecting arm and is a reverse four-bar. Due to the different installation positions of the reverse connecting arm, the active rotating seat is closer to the outside and the rotating clamping disk is closer to the inside, which has a larger transmission ratio. When the laser installation mechanism drives the active rotating seat to rotate, the rotating clamping disk rotates in the opposite direction at a larger angle and drives the material to rotate, so that the laser installation mechanism only needs to rotate in an arc to engrave the entire material. The engraving position of the laser engraving head is controlled by the adjustment arm and the adjustment disk.

[0018] S3. When rotary engraving is required, the switching cylinder extends to drive the cylinder connecting arm, the meshing control arm and the meshing connecting claw forward, and finally makes the tooth groove meshing teeth on the meshing connecting claw mesh with the meshing gear groove on the rotation control column. At this time, the laser installation mechanism performs a circular rotation, which drives the active rotating seat to rotate through the meshing of the gear tooth groove to realize the subsequent reverse rotation. When plane engraving is required, the switching cylinder retracts the cylinder connecting arm, and the tooth groove meshing teeth are no longer meshed with the meshing gear groove on the rotation control column, then the follow-up steering mechanism is not started, and the moving path of the laser installation mechanism is The control is realized by the path switching mechanism. The moving connection seat at the bottom of the laser installation mechanism penetrates the sliding linkage plate and the deformation slot plate and is slidably connected. The sliding linkage plate is connected to the cam groove on the outer cylindrical cam column through the driven moving column. After the driving motor is started, the driven moving column realizes reciprocating direct motion through the symmetrical and end-to-end spiral cam grooves, and drives the sliding linkage plate to reciprocate and direct motion to control the laser installation mechanism to move back and forth on the deformation slot plate. At this time, if the deformation slot plate is vertical, the laser installation mechanism moves horizontally. If the deformation slot plate is curved, the laser installation mechanism rotates in an arc shape.

[0019] S4. When the switching cylinder is in the center position, the cylinder connecting arm is extended or retracted, and the displacement linkage seat will be pulled or pushed out through the displacement control plate connected to it. The displacement linkage seat is provided with a control plate passing slot so that the displacement control plate can pass horizontally and will not contact when following the rotation of the switching cylinder. The displacement linkage seat is driven to move only when pushed and pulled longitudinally. When the switching cylinder is extended, the displacement linkage seat is pushed open, and the extrusion sliding seats on both sides are pulled inward by the extrusion connecting arms on both sides, and the double-end extrusion blocks on the top of the extrusion sliding seat are driven inward to pull and extrude, thereby squeezing the top deformation chain belt to bend it, and at the same time bending the deformation slot plate connected to it to deform it into an arc. Since the switching cylinder will rotate in an arc at this time, the displacement control plate will leave the displacement linkage seat At this time, the maintaining springs connected between the extrusion sliding seats will be pulled closer to each other to maintain the extrusion sliding seat, the displacement linkage seat and the top double-end extrusion block in an extruded state. When the switching cylinder is in the center position again, the displacement linkage seat is retracted and pulled back, and the extrusion connecting arms on both sides push the extrusion sliding seats on both sides outward, and no longer extrude the deformation chain and the deformation slot plate. Similarly, because the switching cylinder will move laterally, the displacement control plate will leave the displacement linkage seat. At this time, the maintaining springs connected between the extrusion sliding seats will still be pulled closer to each other, but because the extrusion connecting arms are collinear at this time, the torque generated by the tension of the maintaining spring passing through the midpoint angle is zero and is also zero, and will not pull the extrusion sliding seat to maintain the extrusion sliding seat, the displacement linkage seat and the top double-end extrusion block in a released state.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] In the present invention, through the cooperation of the inner and outer clamping mechanisms and the follow-up steering mechanism, when engraving a circular material, the laser installation machine moves along a fixed arc path after installing the laser engraving head. The follow-up steering mechanism drives the active rotating seat to rotate due to the control of the path switching mechanism. The active rotating seat is connected to the rotating clamping disk through the reverse connecting arm and is a reverse four-bar. Moreover, due to the different installation positions of the reverse connecting arm, the active rotating seat is closer to the outside and the rotating clamping disk is closer to the inside, which has a larger transmission ratio. When the laser installation mechanism drives the active rotating seat to rotate, the rotating clamping disk rotates in the opposite direction at a larger angle and drives the material to rotate, so that the laser installation mechanism only needs to rotate in an arc to engrave the entire material, so that the laser can have a larger engraving range through a smaller rotation activity, so that when engraving a cylinder, the material can be engraved around the entire circumference without taking out the material many times.

[0022] In the present invention, through the cooperation of the inner and outer clamping mechanisms and the follow-up steering mechanism, when engraving a flat material, the laser installation machine moves along a fixed straight path after installing the laser engraving head, and the follow-up steering mechanism is closed at this time.

[0023] In the present invention, the moving path of the laser installation mechanism and the opening and closing control of the follow-up steering mechanism are simultaneously controlled by the path switching mechanism, and the laser engraving machine is quickly switched between different engraving modes through a series of components that cooperate with each other. The mechanism is composed of a top fixing frame, a sliding limit groove, a sliding linkage plate and other components. These components work together to ensure that the laser installation mechanism can smoothly switch between the rotation and plane engraving modes. The switching cylinder controls the position of the cylinder connecting arm and the meshing control arm, thereby determining whether the meshing connecting claw is engaged with the rotation control column. In addition, the mechanism also controls the bending degree of the deformed groove plate through the cooperation of the double-end extrusion block and the deformed chain belt, thereby adjusting the moving path of the laser installation mechanism. The entire mechanism is exquisitely designed and responds quickly, which can ensure the operation of the laser engraving machine in different engraving modes, while improving the flexibility and processing accuracy of the equipment.

A chain limit plate 6121 is fixed on each chain plate of the deformable chain belt 612 to limit the maximum bending radius to control the bending degree of the deformable slot plate 614. The deformable chain belt 612 is connected to the deformable slot plate 614 through a chain mounting ring 613 to achieve bending deformation and be installed on its surface. The clamping or loosening state of the double-ended extrusion block 610 is controlled by the extrusion sliding seat 618 at the bottom. The position of the extrusion sliding seat 618 is controlled by the maintaining spring 619 and the displacement linkage seat 615. When the displacement linkage seat 615 pulls the extrusion sliding seats 618 on both sides through the extrusion connecting arm 617, it is pushed inward and the maintaining spring 619 is used. 19 also pulls the extrusion sliding seats 618 on both sides inward to maintain the clamping state of the double-end extrusion block 610. When the displacement linkage seat 615 pushes the extrusion sliding seat 618 until the extrusion connecting arms 617 on both sides are in line, the spring 619 constrains the angle of the connection point to zero and cannot pull the extrusion sliding seat 618, so as to maintain the release state of the double-end extrusion block 610. The double-end extrusion block 610 controls the bending degree of the deformation slot plate 614 and the cylinder connecting arm 66 controls the engagement of the rotation control column 55 synchronously, and the movement of the laser installation mechanism 7 is controlled by the cam structure formed by the cylindrical cam column 620 and the sliding linkage plate 63, so that the states of each mechanism of the laser installation mechanism 7 are carried out simultaneously when rotating and linearly moving.

[0044] The driven moving column 631 penetrates the outer surface of the top fixed frame 61 and is slidably connected to the inner wall thereof, the meshing control arm 67 penetrates the cylinder mounting frame 64 and is slidably connected thereto, the displacement control plate 68 is an arc-shaped plate and the arc takes the rotation axis of the rotating control column 55 as the center and the radius is the distance from the rotating control column 55 to the control plate through the groove 6151 when the meshing gear groove 551 is engaged with the tooth groove meshing tooth 691, the number of the double-end extrusion blocks 610 is two, and the double-end extrusion blocks 610 are symmetrically distributed with the top fixed frame 61 as the central axis, the double-end extrusion blocks 610 are fixedly connected to the top surface of the extrusion sliding seat 618, the connection block limiting groove 6101 is inclined, the chain connection blocks 611 are symmetrically distributed at both ends of the deformed chain belt 612, the deformed chain belt 612 is hinged head to tail by multiple chain plates, and the extrusion sliding seat 618 is connected to the bottom sliding seat 618. The inner surface of the movable groove 6161 is slidingly connected, there are two extrusion sliding seats 618, and the extrusion sliding seats 618 are symmetrically distributed with the central axis of the bottom fixed frame 616 as the symmetry axis, and the two ends of the maintenance spring 619 are fixedly connected to the extrusion sliding seats 618 on both sides. The cam groove 6201 is a spiral line wrapped around the cylindrical cam column 620 and is symmetrically distributed end to end. The driven moving column 631 is slidingly connected to the inner surface of the cam groove 6201, and the output end of the driving motor 621 is fixedly connected to the cylindrical cam column 620. The bending radius of the inner chain plate of the deformed chain belt 612 is controlled by the chain limit plate 6121, and the two ends of the deformed chain belt 612 are connected to the double-end extrusion block 610 through the chain connecting block 611. When the double-end extrusion block 610 moves outward, it will pull the chain connecting block 611 to restore it to a rectangle.

[0045] The laser mounting mechanism 7 includes a movable connecting seat 71, which passes through the sliding linkage plate 63 and the deformation groove plate 614 and is slidably connected to the inner wall thereof. The top surface of the movable connecting seat 71 is fixedly connected to a mounting sliding seat 72, and the top surface of the mounting sliding seat 72 is installed with a longitudinal adjustment arm 73, and the top surface of the longitudinal adjustment arm 73 is installed with an angle adjustment disk 74, and the outer surface of the angle adjustment disk 74 is installed with a universal adjustment arm 75, and one end of the universal adjustment arm 75 is fixedly connected to a laser engraving head 76. The moving path of the laser mounting mechanism 7 is controlled by the path switching mechanism 6, and its own minor adjustments such as height angle are controlled by its own longitudinal adjustment arm 73, angle adjustment disk 74 and universal adjustment arm 75.

[0046] The bottom surface of the mobile connecting seat 71 is fixedly connected to the top surface of the cylinder mounting frame 64, and the mounting sliding seat 72 is slidingly connected to the top surface of the sliding linkage plate 63. The mobile connecting seat 71 passes through the sliding linkage plate 63 and the deformation slot plate 614. There is only one unique intersection point formed by the sliding linkage plate 63 and the deformation slot plate 614. When the sliding linkage plate 63 reciprocates, it will push the mobile connecting seat 71 to move in the deformation slot plate 614, and move in a straight line when the deformation slot plate 614 is rectangular, and move in an arc shape when it is arc-shaped, and drive the laser mounting mechanism 7 at the top and the switching cylinder 65 at the bottom and other components to move or rotate.

[0047] In this embodiment, Figure 1 , Figure 2 As shown, the device mounting base 1 is used to mount internal components and plays a supporting role internally through the internal mounting plate 3;

[0048] In this embodiment, Figure 3 As shown, the outer surface of the clamping installation shell 41 is fixedly connected to the device installation base 1, the clamping installation shell 41 is provided with three clamping sliding grooves 411, and a pair of clamping installation columns 42 and a clamping sliding block 48 are respectively installed, and the rotating clamping plate 51 is rotatably connected to the inner surface of the clamping installation shell 41;

[0049] In this embodiment, Figure 4 As shown, the bottom is fixed and the top is adjusted in height by a height-adjusting cylinder 43 to accommodate materials of different sizes. In addition to the clamping effect, the arc-shaped clamping jaw 45 is installed with a clamping transmission belt 461 through a transmission mounting column 46 so that the material can rotate inside to cooperate with the subsequent follow-up steering mechanism 5.

[0050] In this embodiment, Figure 5 As shown, the rotating clamping plate 51 is connected to the active rotating seat 54 through a reverse four-bar structure. When the device is in operation, the active rotating seat 54 rotates and reverses and amplifies through the reverse connecting arm 53, so that the laser can engrave a larger range through smaller rotation activities.

[0051] In this embodiment, Figure 6 As shown, the top fixing frame 61 and the bottom fixing frame 616 are used to install the path switching mechanism 6 components and to provide grooves for limiting the moving paths of some components;

[0052] In this embodiment, Figure 7As shown, the movable connection seat 71 penetrates the sliding linkage plate 63 and the deformable slot plate 614 and is slidably connected with the inner wall thereof. The sliding linkage plate 63 and the deformable slot plate 614 form only one intersection which is unique. When the sliding linkage plate 63 moves back and forth, it will push the movable connection seat 71 to move in the deformable slot plate 614, and move in a straight line when the deformable slot plate 614 is rectangular, and move in an arc shape when it is arc-shaped, and drive the laser installation mechanism 7 at the top and the switching cylinder 65 at the bottom and other components to move or rotate;

[0053] In this embodiment, Figure 8 As shown, the switching cylinder 65 pulls or pushes out the displacement linkage seat 615 through the displacement control plate 68 connected thereto, and the displacement linkage seat 615 is provided with a control plate passing slot 6151 so that the displacement control plate 68 can pass through horizontally and will not contact the displacement linkage seat 615 when following the rotation of the switching cylinder 65, and only drives the displacement linkage seat 615 to move when pushed or pulled longitudinally;

[0054] In this embodiment, Fig. 9 As shown, when the switching cylinder 65 is extended, the displacement linkage seat 615 is pushed open, and the extrusion sliding seats 618 on both sides are pulled inward by the extrusion connecting arms 617 on both sides, and the double-ended extrusion block 610 on the top of the extrusion sliding seat 618 is pulled inward for extrusion, thereby extruding the top deformation chain belt 612 to bend it, and at the same time bending the deformation slot plate 614 connected thereto to deform it into an arc shape. Since the switching cylinder 65 will rotate in an arc shape at this time, the displacement control plate 68 will leave the displacement linkage seat 615. At this time, the maintenance springs 619 connected between the extrusion sliding seats 618 will be pulled closer to each other to maintain the extrusion sliding seat 618, the displacement linkage seat 615 and the top double-ended extrusion block 610 in an extruded state;

[0055] In this embodiment, Fig.10 As shown, when the switching cylinder 65 is in the center position again, the displacement linkage seat 615 is retracted and pulled back, and the extrusion connecting arms 617 on both sides push the extrusion sliding seats 618 on both sides outward, and no longer extrude the deformation chain and the deformation slot plate 614. Similarly, because the switching cylinder 65 will move laterally, the displacement control plate 68 will leave the displacement linkage seat 615. At this time, the maintenance springs 619 connected between the extrusion sliding seats 618 will still be pulled closer to each other, but because the extrusion connecting arms 617 are collinear at this time, the torque generated by the tension of the maintenance spring 619 passing through the midpoint angle is zero and will not pull the extrusion sliding seat 618, so as to maintain the extrusion sliding seat 618, the displacement linkage seat 615 and the top double-ended extrusion block 610 in a released state;

[0056] In this embodiment, Fig.11As shown, the bending radius of the inner chain plate of the deformed chain belt 612 is controlled by the chain limit plate 6121, and the two ends of the deformed chain belt 612 are connected to the double-end extrusion block 610 through the chain connection block 611. When the double-end extrusion block 610 moves outward, it will pull the chain connection block 611 to restore it to a rectangle;

[0057] In this embodiment, Fig.12 As shown, the sliding linkage plate 63 is connected to the cam groove 6201 on the outer cylindrical cam column 620 through the driven moving column 631. After the driving motor 621 is started, the driven moving column 631 realizes reciprocating linear motion through the symmetrical and end-to-end spiral cam groove 6201.

[0058] A method for using a device and method for engraving artworks, comprising the following steps:

[0059] S1. Place the raw material to be clamped and engraved on the rotating clamping plate 51, start the three-point bevel gear set 521 to drive the three three-claw clamps 52 distributed in an annular manner to push inward and clamp the material, start the clamping adjustment cylinder 47 to push the clamping sliding block 48 to pull the clamping installation column 42 through the clamping connecting arms 49 connected on both sides, and the clamping installation column 42 gathers inward along the clamping sliding groove 411 and clamps the material through the arc-shaped clamping jaws 45 connected to the clamping jaw connecting arm 44. The bottom clamping jaw connecting arm 44 is fixed at a constant height, and the top is adjusted by the height adjustment cylinder 43 to clamp raw materials of different heights.

[0060] S2, the laser installation mechanism 7 is connected to the path switching mechanism 6 through the mobile connecting seat 71 and the installation sliding seat 72 to control the moving path, and the position and angle of the laser engraving head 76 are adjusted through the longitudinal adjustment arm 73, the angle adjustment disk 74 and the universal adjustment arm 75, and the clamped material is laser engraved. When the laser installation mechanism 7 moves horizontally, the follow-up steering mechanism 5 is controlled by the path switching mechanism 6 and does not work for plane engraving. When the laser installation mechanism 7 rotates in a circle, the follow-up steering mechanism 5 is controlled by the path switching mechanism 6 to make the laser installation mechanism 7 drive the active rotating seat 54 to rotate. The active rotating seat 54 is connected to the rotating clamping disk 51 through the reverse connecting arm 53 and is a reverse four-bar. Moreover, due to the different installation positions of the reverse connecting arm 53, the active rotating seat 54 is closer to the outside and the rotating clamping disk 51 is closer to the inside, and has a larger transmission ratio. When the laser installation mechanism 7 drives the active rotating seat 54 to rotate, the rotating clamping disk 51 rotates in the opposite direction at a larger angle and drives the material to rotate, so that the laser installation mechanism 7 only needs to rotate in an arc to engrave the entire material. The engraving position of the laser engraving head 76 is controlled by the adjustment arm and the adjustment disk;

[0061] S3. When rotary engraving is required, the switching cylinder 65 extends to drive the cylinder connecting arm 66, the meshing control arm 67 and the meshing connecting claw 69 forward, and finally makes the tooth groove meshing teeth 691 on the meshing connecting claw 69 mesh with the meshing gear groove 551 on the rotation control column 55. At this time, the laser installation mechanism 7 rotates in a circle, which drives the active rotating seat 54 to rotate through the meshing of the gear teeth to achieve subsequent reverse rotation. When plane engraving is required, the switching cylinder 65 retracts the cylinder connecting arm 66, and the tooth groove meshing teeth 691 are no longer meshed with the meshing gear groove 551 on the rotation control column 55, then the follow-up steering mechanism 5 is not started, and the movement path of the laser installation mechanism 7 is controlled by the path The switching mechanism 6 is realized, the movable connection seat 71 at the bottom of the laser installation mechanism 7 penetrates the sliding linkage plate 63 and the deformation slot plate 614 and is slidably connected, the sliding linkage plate 63 is connected to the cam groove 6201 on the outer cylindrical cam column 620 through the driven moving column 631, and after the driving motor 621 is started, the driven moving column 631 realizes reciprocating direct motion through the symmetrical and end-to-end spiral cam groove 6201, and drives the sliding linkage plate 63 to reciprocate and direct motion to control the laser installation mechanism 7 to move back and forth on the deformation slot plate 614. At this time, if the deformation slot plate 614 is vertical, the laser installation mechanism 7 moves horizontally, and if the deformation slot plate 614 is curved, the laser installation mechanism 7 rotates in an arc shape;

[0062] S4. When the switching cylinder 65 is in the center position, the cylinder connecting arm 66 is extended or retracted, and the displacement linkage seat 615 is pulled or pushed out through the displacement control plate 68 connected thereto. The displacement linkage seat 615 is provided with a control plate passing groove 6151 so that the displacement control plate 68 can pass through horizontally and will not contact when following the rotation of the switching cylinder 65. The displacement linkage seat 615 is driven to move only when pushed and pulled longitudinally. When the switching cylinder 65 is extended, the displacement linkage seat 615 is pushed open, and the extrusion sliding seats 618 on both sides are pulled inward by the extrusion connecting arms 617 on both sides, and the double-ended extrusion blocks 610 on the top of the extrusion sliding seat 618 are pulled inward for extrusion, thereby squeezing the top deformation chain belt 612 to bend it, and at the same time bending the deformation slot plate 614 connected thereto to make it deform into an arc shape. At this time, since the switching cylinder 65 will rotate in an arc shape, the displacement control plate 68 will leave the displacement linkage seat 615. The maintaining springs 619 connected between the pressing sliding seats 618 will be pulled closer to each other to maintain the extrusion sliding seat 618, the displacement linkage seat 615 and the top double-ended extrusion block 610 in an extruded state. When the switching cylinder 65 is in the center position again, the displacement linkage seat 615 is retracted and pulled back, and the extrusion connecting arms 617 on both sides push the extrusion sliding seats 618 on both sides outward, and no longer extrude the deformation chain and the deformation slot plate 614. Similarly, since the switching cylinder 65 will move laterally, the displacement control plate 68 will leave the displacement linkage seat 615. At this time, the maintaining springs 619 connected between the extrusion sliding seats 618 will still be pulled closer to each other, but since the extrusion connecting arms 617 are collinear at this time, the torque generated by the tension of the maintaining spring 619 passing through the midpoint angle is zero is also zero, and the extrusion sliding seat 618 will not be pulled to maintain the extrusion sliding seat 618, the displacement linkage seat 615 and the top double-ended extrusion block 610 in a released state.

At this time, the laser installation mechanism (7) performs a circular rotation, which drives the active rotating seat (54) to rotate through the meshing of the gear teeth to achieve subsequent reverse rotation. When plane engraving is required, the switching cylinder (65) retracts the cylinder connecting arm (66), and the tooth groove meshing teeth (691) and the meshing gear groove (551) on the rotation control column (55) are no longer meshed, and the follow-up steering mechanism (5) is not started. The control of the moving path of the laser installation mechanism (7) is realized by the path switching mechanism (6). The movement of the bottom of the laser installation mechanism (7) The connecting seat (71) penetrates the sliding linkage plate (63) and the deformation slot plate (614) and is slidably connected. The sliding linkage plate (63) is connected to the cam groove (6201) on the outer cylindrical cam column (620) through the driven moving column (631). After the driving motor (621) is started, the driven moving column (631) realizes reciprocating direct motion through the symmetrical and end-to-end spiral cam groove (6201), and drives the sliding linkage plate (63) to reciprocate and control the laser installation mechanism (7) to move back and forth on the deformation slot plate (614). At this time, if the deformation slot plate (614) is vertical, it drives the laser installation mechanism (7) to move horizontally on the deformation slot plate (614) and the sliding linkage plate (63). If the deformation slot plate (614) is curved, it drives the laser installation mechanism (7) to rotate in an arc on the deformation slot plate (614) and the sliding linkage plate (63). S4. When the switching cylinder (65) is at the center position, the cylinder connecting arm (66) is extended or retracted, and the displacement linkage seat (615) is pulled or pushed out through the displacement control plate (68) connected thereto. The displacement linkage seat (615) is provided with a control plate passing groove (6151) so that the displacement control plate (68) can pass through horizontally and will not contact the displacement linkage seat (615) when following the rotation of the switching cylinder (65). The displacement linkage seat (615) is driven to move only when pushed or pulled longitudinally. When the switching cylinder (65) is extended, the displacement linkage seat (615) is pushed or pushed out. 615) is pushed open, and the extrusion sliding seats (618) on both sides are pulled inwards through the extrusion connecting arms (617) on both sides, and the double-end extrusion blocks (610) on the top of the extrusion sliding seat (618) are pulled inwards for extrusion, thereby extruding the top deformation chain belt (612) to bend it, and at the same time, the deformation slot plate (614) connected thereto is bent to make it deform into an arc shape. At this time, since the switching cylinder (65) will rotate in an arc shape, the displacement control plate (68) will leave the displacement linkage seat (615), and at this time, the extrusion The maintenance springs (619) connected between the sliding seats (618) will be pulled closer to each other to maintain the extrusion state of the extrusion sliding seat (618), the displacement linkage seat (615) and the top double-end extrusion block (610). When the switching cylinder (65) is in the center position again, the retracted displacement linkage seat (615) is pulled back, and the extrusion connecting arms (617) on both sides push the extrusion sliding seats (618) on both sides outward, and no longer squeeze the deformation chain and the deformation slot plate (614). Similarly, due to the switching cylinder (65) ) will move laterally, and the displacement control plate (68) will leave the displacement linkage seat (615). At this time, the maintenance springs (619) connected between the extrusion sliding seats (618) will still pull each other closer, but because the extrusion connecting arms (617) are collinear at this time, the torque generated by the tension of the maintenance spring (619) passing through the midpoint angle is zero and will not pull the extrusion sliding seat (618), so as to maintain the extrusion sliding seat (618), the displacement linkage seat (615) and the top double-ended extrusion block (610) in a released state.
