The specific embodiment

Below in conjunction with accompanying drawing the utility model is made concrete further instruction.

As shown in the figure, comprise housing 1, and be provided with the pull bar 11 of keeping supplying lower slider in the housing 1, be connected with first spring 2 between housing 1 and the pull bar 11, second spring 3 is arranged in the pull bar 11, second spring, 3 one ends connect rolling wheel support 7, one hook 4 is articulated in pull bar 11 by axle sleeve 5, linking up with 4 one ends is buckled on the bearing 9, rolling wheel support 7 is provided with roller 6, its described pull bar 11 is provided with arc opening 1101, and the axostylus axostyle of rolling wheel support 7 is inserted in arc opening 1101, is hinged with support chip 12 on the described rolling wheel support 7 and between the pull bar 11.

Be respectively arranged with circular arc 402, arc chimb 401 and arc recess 403 on the described hook 4, circular arc 403, arc chimb 401 and arc recess 402 link to each other.

Described pull bar 11 is provided with spring support 8, and spring support 8 one ends are fixed on pull bar 11, and the other end of spring support 8 is connected on the rolling wheel support 7.

Described second spring 3 is enclosed within on the spring support 8, and the one end peaks on the spring support 8, and the other end peaks on the rolling wheel support 7.

Described arc opening 1101 one in keep to the side to be concave shaped.

Described support chip 12 is provided with recess 1201, and reference column 1102 is set on the pull bar 11, and reference column 1102 is embedded in recess 1201 places.

Hook 4 is provided with stator 10.
