[0049] Furthermore, in order to facilitate quick release, the force of the energy storage spring 104 in this application is greater than the sum of the force of the mechanism spring 23 of the disengagement mechanism 20, the force required for the disengagement of the body 30, and the frictional force of the disengagement mechanism 20. In this way, the energy storage spring 104 can overcome the total force of the mechanism spring 23, the force required for the disengagement of the body 30, and the frictional force of the disengagement mechanism 20, and easily release the product, reducing the risk of slippage or difficulty in release, and making the release performance more stable and reliable.
