The specific embodiment

Please refer to shown in Fig. 1 to Fig. 5, the concrete structure that it has demonstrated the preferred embodiment of the utility model, includes base 10, slide block 20, buffer 30, rotary switch 40 and for clashing into the outer rail 50 of rotary switch 40.

Wherein, on this base 10, be provided with the first chute 11, the second chute 12 and the 3rd chute 13, the 3rd chute 13 is between the first chute 11 and the second chute 12, two inner sides, outer end of the 3rd chute 13 are respectively arranged with the first switch groove 14 and second switch groove 15, the first switch groove 14 shifts to install with second switch groove 15, and the first switch groove 14 and second switch groove 15 are all communicated with the 3rd chute 13.

The both sides of this slide block 20 insert in respectively in the first chute 11 and the second chute 12, and slide block 20 moves around along the first chute 11 and the second chute 12, on this slide block 20, is provided with guide channel 21.

The two ends of this buffer 30 are connected with slide block 20 with base 10 respectively, between base 10 and slide block 20, are also connected with back-moving spring 60; Particularly, in the present embodiment, this buffer 30 is oil buffer, and it includes cylinder body 31 and is connected in the piston rod 32 in cylinder body 31, and this cylinder body 31 is fixed on base 10, and piston rod 32 is connected with the end of slide block 20; And in the present embodiment, this cylinder body 31 is fixed on the left side of base 10, piston rod 32 is connected with the left side of the end of slide block 20, and one end of this back-moving spring 60 is connected in the right side of base 10, and back-moving spring 60 other ends are connected in the right side of the end of slide block 20.

This rotary switch 40 is arranged at the inner of slide block 20 rotationally, and rotary switch 40 has fixture block 41 and hooks groove 42, and this fixture block 41 and the 3rd chute 13 and the first switch groove 14, second switch groove 15 are suitable.

The inner both sides of this outer rail 50 convex with two guiding convex closures 51, two guiding convex closures 51 are butted on respectively on the two sides of slide block 20, with guiding outer rail 50, move around, and the inner of this outer rail 50 is also provided with for clashing into the shock post 52 of rotary switch 40, it is suitable with aforementioned guide channel 21 and hook groove 42 that this clashes into post 52.
