[0030] A specific application of this embodiment is as follows: when in use, the device is first installed in the corresponding position. When the spring pull rod needs to be installed, the pull rod 223 can be pulled to make it away from the connecting block 215. When the pull rod 223 is pulled, pressure is applied to the spring 1 225 through the limit ring 222, causing it to elastically deform and generate elastic force. When the pull rod 223 is completely away from the connecting block 215, the clamping claw 214 can be opened under the action of the base 212 and the hinge block 213. At this time, the pull rod 223 can be released to make the spring 1 225 move freely. 25 rebounds under the action of elastic force. After placing the spring pull rod between the clamping jaw 1 211 and the clamping jaw 2 214, the clamping jaw 214 can be pressed toward the direction of the clamping jaw 1 211, so that the connecting block 215 exerts pressure on the pull rod 223 under its action, compressing the spring 1 225, causing elastic deformation and generating elastic force. When the clamping jaw 214 is completely in contact with the clamping jaw 1 211, the pull rod 223 will rebound into the groove 1 216 under the action of the elastic force of the spring 1 225. After the work is completed, the spring pull rod can be taken out in the same way, so that when the clamping jaw 214 is in contact with the clamping jaw 1 211, the pull rod 223 will rebound into the groove 1 216 under the action of the elastic force of the spring 1 225. When the spring pull rod is fixed and installed, the steps are relatively simple, time-saving and labor-saving, and the staff do not need to spend a lot of time on its installation, which greatly shortens the processing time, reduces the staff's work intensity, improves work efficiency, and reduces production costs. After the spring pull rod is installed, if it is necessary to stretch the spring, the handle 321 can be shaken to drive the two-way threaded rod 313 to rotate through the ratchet gear 315. When the two-way threaded rod 313 rotates, the two sliders 314 will move away from each other under the action of the groove three 311. When the sliders 314 move away from each other, the two quick installation mechanisms 2 will move away from each other, so that the spring pull rod is stretched. At this time, the handle 321 is released, which will ensure that the ratchet gear 315 will not reverse under the action of the anti-reversal component 32, making it more convenient to stretch the spring, save time and effort, and the staff does not need to stretch it manually, avoiding the danger that may occur when stretching the spring, ensuring the work safety of the staff, reducing work intensity, improving production efficiency, and ensuring the stability of product quality.
