Namely, the guide hole 1b is a strip-shaped hole, the length direction of the guide hole 1b is parallel to or overlapped with the length direction of the spring barrel 1, and the length direction of the guide hole 1b is also parallel to the axial direction of the spring barrel 1.
Both the spring 9 and the flange 2 are arranged inside the spring holder 1, the flange 2 being slidable in its axial direction inside the spring holder 1 for compressing a first end of the spring 9. Namely, the flange 2 can slide along the axial direction of the spring holder 1 in the spring holder 1, and when the flange 2 can slide along the axial direction of the spring holder 1 in the spring holder 1, the first end of the spring 9 is compressed, and the spring 9 is compressed to realize the energy storage of the spring 9. The guide 5 is fixedly connected with the flange 2, a part of the guide 5 is embedded in the guide hole 1b, and when the flange 2 slides in the axial direction of the spring holder 1 in the spring holder 1, the guide 5 slides along the guide hole 1 b. When the flange 2 compresses the spring 9, the flange 2 carries the guide 5 to slide along the direction parallel to the axial direction of the spring cylinder 1.
One end of the pulling piece is connected with the flange 2, and when the pulling piece is pulled, the pulling piece drives the flange 2 to slide in the spring cylinder 1 along the axial direction of the spring cylinder. Specifically, the other end of the pulling member may be pulled to apply a pulling force to the pulling member. The stored energy indicating plate 7 is arranged outside the spring barrel 1, and an indicating mark for indicating the energy storage state of the spring 9 is arranged on the stored energy indicating plate 7. The state of the spring 9 can be determined by the relative positional relationship between the setting portion 5a of the guide 5 and the indicator. When the setting part 5a of the guide 5 is opposite to a certain area of the indication mark, the spring 9 is in a normal state; when the set part 5a of the guide 5 is opposite to the other area of the indication mark, the state that the energy storage of the spring 9 is insufficient is shown; when the setting portion 5a of the guide 5 is opposite to the other region of the indication mark, the spring 9 is in the state of excessive energy storage.
When the spring operating mechanism provided by the embodiment is applied, the pulling piece is pulled, the pulling piece drives the flange 2 to slide along the axial direction of the spring cylinder 1, the flange 2 slides along the axial direction of the spring cylinder 1 to compress the spring 9, meanwhile, the flange 2 also drives the guide piece 5 to slide along the guide hole 1b, and the state of the spring 9 can be determined by observing the relative position relationship between the set part 5a of the guide piece 5 and the indication mark.

As shown in fig. 1, a mark, a second mark 7b and a third mark 7c are sequentially arranged from left to right. When the set portion 5a of the guide 5 is opposed to the region between the second mark 7b and the third mark 7c, it means that the spring 9 is in the normal operating range; here, it should be noted that when the setting portion 5a of the guide 5 is opposite to the second mark 7b or the third mark 7c, it means that the spring 9 is in the normal operating range. When the set part 5a of the guide piece 5 is opposite to the area between the first mark 7a and the second mark 7b, the energy storage of the spring 9 is insufficient, and the pulling piece needs to be overhauled at the moment; it should be noted that, when the set portion 5a of the guide 5 is opposite to the first mark 7a, the stored energy of the spring 9 is insufficient, and at this time, the pulling member needs to be repaired. That is, when the spring 9 is opposed to the first mark 7a or the region between the first mark 7a and the second mark 7b, the amount of compression of the spring 9 is insufficient and the stored energy is insufficient. In this case, the length of the pulling member may be increased due to wear or the like, and the spring 9 may be insufficiently charged due to the increased length of the pulling member, so that the pulling member needs to be inspected. When the pulling part comprises the chain 8, the length of the chain 8 is lengthened, the pin is possibly abraded, the strength is reduced, and even the chain 8 is broken, so that the potential safety hazard can be eliminated when the chain 8 is overhauled.
