Meanwhile, after the spring mechanism is assembled and sleeved on the spring protection sleeve 1, the end part of the second end 12 of the spring protection sleeve also needs to be subjected to closing-in operation; namely, the tube wall of the second end 12 of the spring protection sleeve is bent inwards by a stamping device, and a second annular end surface 121 is formed by stamping to limit the spring mechanism; the second annular end surface 121 formed by punching should be attached to the hook base 10 and ensure that the inner diameter of the second annular end surface 121 is smaller than the outer diameter of the hook base 10.
When the first end 21 of the telescopic rod extends outwards relative to the first end 11 of the spring protection sleeve and moves away from the second end 12 of the spring protection sleeve, the telescopic rod 2 compresses the first compression spring 3 and the second compression spring 4, and the compression springs store compression elasticity;
when the first end 21 of the telescopic rod is required to contract inwards relative to the first end 11 of the spring protection sleeve to move close to the second end 12 of the spring protection sleeve, the telescopic rod 2 retracts inwards under the action of the compression elastic force of the first compression spring 3 and the second compression spring 4, and the first compression spring 3 and the second compression spring 4 are reset.
In conclusion, the spring device is provided with the spring protection sleeve 1, so that each compression spring can be positioned in a relatively sealed independent space, scraping and collision among compression spring bodies are avoided, the compression springs are prevented from being broken, and the service life of the spring device is prolonged; the spring device adopts the compression spring to replace an extension spring in the prior art, and the working characteristics of the compression spring determine that the spring device has longer service life and is not easy to break, so the compression spring further prolongs the service life of the spring device;
moreover, the compression spring is sleeved and limited on the telescopic rod 2, and the second end 22 of the telescopic rod and the compression spring are both limited in the spring protection sleeve 1, so that the compression spring is still sleeved on the telescopic rod 2 even if the compression spring is broken, and at the moment, the second end 22 of the telescopic rod is still limited in the spring protection sleeve 1, namely, the spring device cannot completely lose the stretching function due to the breakage of the compression spring; therefore, under the mutual matched action of the spring protection sleeve 1 and the telescopic rod 2, the spring device can avoid the potential safety hazard caused by the fact that the barrier comprising the spring device is suddenly knocked down due to the fracture of the compression spring.
