as shown in fig. 1, the invention comprises a support frame 1, a handle 2 arranged on the support frame 1 in a swinging way, a pair of sliding pins 3 and a spring ring 4, and is characterized in that both sides of the support frame 1 are provided with guide structures 101, the pair of sliding pins 3 are respectively arranged on the guide structures 101 on both sides of the support frame 1 in a sliding way, the sliding pins 3 are provided with a hole-shaped chute 301, the chute 301 is inclined towards the middle part of the support frame 1 from top to bottom, the handle 2 corresponding to the chute 301 is provided with a bent driving rod 201, the free end of the driving rod 201 is bent towards the middle part of the handle 2, and the spring ring 4 is arranged between the pair of sliding pins 3.

The two sides of the support frame 1 are provided with handle connecting seats 5, and shaft holes 202 on the two sides of the upper edge of the handle 2 are rotatably connected to a rotating shaft 501 on the inner side of the handle connecting seats 5. The handle connecting seat 5 is adopted, so that a certain distance is arranged between the driving rod 201 and the rotating shaft of the handle 2, and the stroke of the driving rod 201 when rotating along with the handle 2 is converted into the stroke of driving the sliding pin 3 to move.

The handle 2 has a plate shape, the back surface of the plate-shaped handle 2 faces the guide structure 101 of the support frame 1, and two curved driving rods 201 are provided on the back surface of the plate-shaped handle 2.

The end of the sliding pin 3 located in the guide structure 101 is provided with a stud 302, and the coil 4 is fitted over the stud 302 and positioned by the stud 302 to prevent displacement of the coil 4.

The guide structure 101 on the support frame 1 comprises a square guide groove 1012 which is arranged at the upper end of the middle part of the support frame 1 and is an opening 1011, square guide holes 1013 which are arranged at two ends of the square guide groove 1012, and the section shape of the part of the sliding pin 3 which is arranged in the guide structure 101 is square, so that the sliding pin 3 can only move back and forth under the action of the guide structure 101 and can not rotate, and when the inclined plane of the free end of the sliding pin 3 is guaranteed to touch the storage box cavity wall, the sliding pin can move towards the support frame under the action of the inclined plane.

The width of the opening 1011 is larger than the width of the chute 301 and smaller than the width of the portion of the sliding pin 3 located in the guide structure 101, so that the entire guide structure 101 becomes a guide hole, thereby further ensuring that the sliding pin 3 can move only left and right in the guide structure 101.

The slide pin 3 includes a driving portion 303, and a tongue portion 304 fixedly coupled to the driving portion 303.
