Detailed description of the invention
Fig. 1 be the utility model proposes a kind of lifter structural schematic diagram.
Specific embodiment
As shown in Figure 1, the utility model proposes a kind of lifters, comprising: driving mechanism, mounting base, pressing plate 1, lead screw 2,
Switch block, driving mechanism are fixed on the second moving assembly, and cutting assembly is fixed in mounting base, and switch block is fixed on peace
Fill on seat, switch block include: close the electromagnetic switch 3 of driving mechanism, electromagnetic switch 3 releases the button 4, is movably connected in
Depression bar assembly in electromagnetic switch 3, driving mechanism are rotatablely connected lead screw 2, and lead screw 2 connects mounting base, and lead screw 2 and pressing plate 1 are in silk
Thick stick 2 is axial relatively fixed, and lead screw 2 drives mounting base to close to the movement of the direction of driving mechanism, and depression bar assembly is close and contacts
Pressing plate, and the press-started button 4 of reaction force of compression plate 1.
When specific works, driving device drives lead screw rotation, and mounting base is made to drive the direction of cutting assembly case driving mechanism
When mobile, since lead screw 2 and pressing plate 1 relatively fixed lead screw 2 is axial, switch block in mounting base is fixed on to pressing plate 1
Mobile, depression bar assembly is close and contacts pressing plate 1, and the press-started button 4 of reaction force of compression plate 1,4 unlatchings electricity of releasing the button
Magnetic switch 3, electromagnetic switch 3 control driving mechanism and stop working, so that lead screw 2 be made to stop rotating, are fixed on cutting in mounting base
It cuts component and stops movement, carry out height limit.
In the present embodiment, further includes: limit assembly, limit assembly include: loop bar 5, the first spring 6,5 thread bush of loop bar
Lead screw 2,1 turning set connecting sleeve lever 5 of pressing plate are connect, the first spring 6 entangles loop bar 5 and acts against the first limit of pressing plate 1 and mounting base
Between face, loop bar 5 is equipped with retaining ring far from 6 one end of the first spring.By being used cooperatively for pressing plate 1 and switch block, in 2 band of lead screw
Dynamic mounting base is to mobile close to the direction of driving mechanism, and the reaction force of depression bar assembly compression plate 1 and press-started button 4 make
Electromagnetic switch 3 is opened, and then driving mechanism is made to stop working, and lead screw 2 stops rotating, and cutting assembly stops moving with mounting base
It is dynamic, carry out height limit.The loop bar 5 that is socketed on screw rod 2 by screw thread, the first spring 6 for being set on loop bar 5, pressing plate
It is equipped with, it is axial relatively fixed in lead screw 2 with pressing plate 1 that lead screw 2 can be made, and drive mounting base to far from drive in lead screw 2
