Claims

[Scope of utility model registration request]

A pair of arm bodies 3 having protrusions 31 at the lower ends for engaging with the recesses 11 of the transport pallet 1 are attached to the frame body 21.
The main body 2 is pivotally supported at the end of the pallet 1, the lifting guide 4 is erected at the center of the frame 21, and a protrusion 22 for abutting against the top of the wall 12 of the pallet 1 is attached to the bottom of the main body 2.
, a sliding fitting 5 which slides along the lifting guide 4 and has a cam 51 pivotally supported on the upper part thereof, and a sliding fitting 5 which is suspended from a lifting device and connected to the main body 2 via a hanging wire 91.
a hanging fitting 6 for suspending the cam 51; an elastic body 7 pivotally supported by the hanging fitting 6; and a pin 81 whose upper end is pivotally supported by the lower end of the elastic body 7 and for engaging with the cam 51. The arm body 3 and the sliding metal fitting 5 are connected to an operating wire 9.
2, and the vertical stroke of the slide fitting 5 causes the protrusion 31 of the arm body 3 to engage with the recess 11 of the pallet 1, or
The cam 51 is pivotally supported at an angle with respect to the vertical line, and
The automatic opening/closing hacker is characterized in that the length of the hanging wire 91 is such that it becomes tensioned after the sliding fitting 5 reaches the top of the lifting stroke.
