Vibrating chamber 11 leans on being fixed with elastic spring board 11.1 on the one side inner wall of mainboard 1, and vibrating chamber 11 inside transfer line 8.5 outer wall sets up to the protruding structure of equidistant distribution to transfer line 8.5 and elastic spring board 11.1 constitute mainboard 1's repeated vibration subassembly jointly, reach vibrating chamber 11 and mainboard 1 use vibration external force transmission, thereby utilize the oscillation effect to realize the quick separation between template and the stair step.

The working principle is as follows: when the anti-damage dismounting device for the building stair template is used, firstly, as shown in figures 1-5, a main board 1 of the device is manually attached to the outer side of a template of a stair step when in use, a positioning piece 5 is rotated to enable a positioning sleeve 4 to slide downwards on a holding rod 3, a positioning force arm 6 is rotated to take the main board out of a fixing jacket 7, one end of a rubber cushion block of the positioning force arm 6 is placed on the stair step, then the positioning piece 5 is rotated to mount and limit the positioning sleeve 4 again, then as shown in figures 3-5, a sucker component 12 on the main board 1 is attached to the template at the moment, then a circuit where a motor body 3.1 is positioned is communicated to lead in forward current in the circuit, and due to the leading-in direction of the current, the motor body 3.1 rotates reversely and an electromagnet 3.2 generates repulsion force to a permanent magnet at the top of a transmission bevel gear 3.3, so that the transmission bevel gear 3.3 moves towards a transmission shaft 3.4, and as shown in fig. 6, the positioning ring 3.6 and the positioning thin rod 3.7 at the bottom of the transmission bevel gear 3.3 completely wrap the outer wall of the transmission shaft 3.4, because the outer wall of the output shaft of the motor body 3.1 and the transmission bevel gear 3.3 are in axial fit sliding and radial clamping connection, when the motor body 3.1 drives the transmission bevel gear 3.3 to rotate, the positioning ring 3.6 and the positioning thin rod 3.7 at the bottom of the transmission bevel gear 3.3 also apply torque to the outer wall of the transmission shaft 3.4, so that the transmission shaft 3.4 synchronously rotates, and the pressure inside the positioning cavity 2 is increased by utilizing the first bevel gear 3.5 between the transmission shaft 3.4 and the turbofan blade 2.1 to achieve that the turbofan blade 2.1 rotates to discharge the gas inside the suction disc component 12 and the ventilation channel 13 and guide the gas into the positioning cavity 2, and as shown in fig. 3-4, the gas guided into the positioning cavity 2 can cause the pressure inside to be increased, so as to push the gas piston 2.4 to displace, so that the gas is discharged from the exhaust port 2.6, and the gas is discharged after the motor body 3.1 and the turbofan stops the movement, the air piston 2.4 resets under the action of a spring and the like to block the sealing separation strip 2.2 again, so that negative pressure is generated in the front half part of the positioning cavity 2, the sucker assembly 12 and the ventilation channel 13, and the air piston and the main board 1 are tightly attached to the outer side of the template in an absorption manner;

according to the above, after the reverse current is led in the circuit of the motor body 3.1 and the electromagnet 3.2, the leading-in direction of the current is changed, the motor body 3.1 rotates forward and the electromagnet 3.2 generates the suction force to the permanent magnet at the top of the transmission bevel gear 3.3, so that the transmission bevel gear 3.3 moves upwards on the outer wall of the output shaft of the motor body 3.1 and is meshed with the second bevel gear 8.2, and the axial attaching sliding and radial clamping connection relationship between the outer wall of the output shaft of the motor body 3.1 and the transmission bevel gear 3.3, the motor body 3.1 directly drives the transmission bevel gear 3.3 to rotate and synchronously rotate the cross bar 8.1 and the second bevel gear 8.2 due to the meshing, when the cross bar 8.1 rotates, as shown in fig. 4 and fig. 7, the gear ring 8.3 at the tail end of the cross bar 8.1 is meshed with the sawtooth strip 9.3 on the push plate 9.2, so that the push plate 9.2 makes rectangular lifting-side-shifting intermittent motion, because the top of the push plate 9.2 is in sliding connection with the bottom of the connecting sleeve 9.1 of the pull rod 9.2, the pushing plate 9.2 can directly push the pull rod 9 to lift when moving, and the transmission bevel teeth 3.3 are engaged with the second bevel teeth 8.2 at the ends of the cross rods 8.1 at the left side and the right side, so that the cross rods 8.1 which are symmetrically distributed at the left side and the right side rotate in opposite directions synchronously, and the pull rods 9 which are symmetrically distributed at the left side and the right side lift in opposite directions synchronously, as shown in fig. 4, a rotating shaft at the upper end of the pull rod 9 can slide in a reserved groove on the embedded plate 10, so that the embedded plate 10 can do asynchronous up-and-down staggered movement at two sides due to the pulling of the pull rod 9, the embedded plate 10 can be more flexibly and efficiently embedded between the template and the stair step, so that the two are separated more rapidly and efficiently, the damage of the two is reduced, as shown in fig. 4 and fig. 8, the rotation of the cross rod 8.1 can drive the transmission rod 8.5 to rotate due to the transmission of the chain belt assembly 8.4, the protruding structure of the outer wall of the rotation transmission rod 8.5 causes the elastic spring plate 11.1 inside the vibration cavity 11 to repeatedly impact, produce high-frequency oscillation, vibration external force is applyed for the template through mainboard 1, the separation efficiency between improvement template and the stair of can be very big is marked time, after its preliminary separation, stop motor body 3.1's start-up, inlay board 10 this moment and mix between stair mark time and the template, then as shown in fig. 2, for pedal location arm of force 6, the position of pulling holding rod 3 orientation right side user rotates, make mainboard 1 and embedding board 10 directly warp because of setting element 5 and location arm of force 6's articulated, reach the effect of quick separation between template and the stair mark time.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and/or modifications of the invention can be made, and equivalents and modifications of some features of the invention can be made without departing from the spirit and scope of the invention.
