[0025] See also Figure 4 and Figure 5 A built-in replaceable shear hinge device, the pusher comprises: a connecting block 17, the connecting block 17 is fixedly installed between the two sliders 15, and slides in the connecting groove 12, a push rod 18 is fixedly installed on the top surface of the two sliders 15, a rotating groove 20 is opened on the top surface of the push rod 18, a clamping block 21 is rotatably connected to the side wall of the rotating groove 20, a clamping groove 22 is opened between the two slide grooves 11, and the clamping groove 22 cooperates with the clamping block 21;

[0026] Working principle:

[0027] When in use, the shear hinge body 8 is firmly fixed between the first floating plate 1 and the second floating plate 2 by the connecting rod 9 and the nut 10, and is fixed in the No. 2 observation port 4 by the fixing seat 7. The setting of high-strength glass enables the staff to clearly observe the situation inside the No. 2 observation port 4 and the first installation groove 5, so as to monitor the working status of the shear hinge body 8 in real time. When the shear hinge body 8 needs to be replaced, the locking assembly is operated to release the shear hinge body 8. The staff pushes the push rod 18 in the push member to make the connecting block 17 slide in the connecting groove 12, thereby driving the two sliders 15 to move in the slide groove 11. As the slider 15 moves, the limit column 16 will disengage from the circular groove on the side wall of the latch 14, and the staff will pull out the latch 14 to release the lock on the shear hinge body 8. After the latch 14 is unlocked, the staff can rotate the block 21 to disengage it from the slot 22, thereby further releasing the constraints of the push rod 18 and the slider 15. At this time, the staff can easily disassemble and replace the shear hinge body 8. After replacing the new shear hinge body 8, the staff needs to fix it again through the locking assembly. The specific operation is the opposite of the unlocking process, that is, by pushing the push rod 18 to move the slider 15 and the limit column 16 to the appropriate position, so that the limit column 16 re-enters the circular groove of the latch 14, thereby locking the shear hinge body 8. Finally, the staff fixes the shear hinge body 8 in the No. 2 observation port 4 through the fixing seat 7, and firmly connects it between the first floating plate 1 and the second floating plate 2 through the nut 10 and the connecting rod 9. At this point, the replacement process of the shear hinge body 8 is completed.
