Specific embodiment

Refering to fig. 1, Fig. 2, Fig. 3, Fig. 4, the utility model include that master pendulum arm 1, secondary swing arm 2, scissors 3 and push button 4 are constituted,

The master pendulum arm 1 is rod-like element, and one end is radially provided with hinge axis hole 14, and side edge is axially arranged with master pendulum arm slot 11, with the perforation of master pendulum arm slot 11 along being axially arranged with push button slot 12 on master pendulum arm 1, along being axially arranged with first in master pendulum arm slot 11 Sliding slot 13；

Secondary swing arm 2 is along the rod-like element for being axially arranged with scissors hole 21 and secondary swing arm slot 23, and one end is radially provided with hinged shaft 22, the interior edge of secondary swing arm slot 23 is axially arranged with second sliding slot 24；

Fig. 2, Fig. 3, Fig. 4, scissors 3 are hingedly formed by two blades, be respectively equipped on the shank of two blades the first sliding rail 31 and Second sliding rail 32, wherein being additionally provided with pin hole 33 on the shank of a blade；

Fig. 1, Fig. 2, push button 4 are the snap close piece that bottom surface is equipped with pin 41, top surface is equipped with rubbing surface.

Refering to fig. 1, Fig. 2, Fig. 3, Fig. 4, the secondary swing arm slot 23 of the pair swing arm 2 and the master pendulum arm slot 11 of master pendulum arm 1 It plugs together side by side and the hinge axis hole 14 of the hinged shaft 22 of secondary swing arm 2 and master pendulum arm 1 is hinged, scissors 3 is worn by the scissors hole 21 of secondary swing arm 2 Enter, and the second sliding rail 32 of 3 shank of scissors is slided with first of 24 slide fit of second sliding slot, 3 shank of scissors in secondary swing arm slot 23 13 slide fit of first sliding groove in rail 31 and master pendulum arm slot 11；
