Connection pedestal 22, the connecting portion 12 is clamped in the U-shaped chamber 200 that left connection pedestal 21 and right connection pedestal 22 are formed, institute
State and be provided with spring 3 between left connection pedestal 21 and right connection pedestal 22.
Furthermore, the lower end of the left connection pedestal 21 forms the first clamping hole 211, and upper end forms to the right
Raised guide limiting stopper 212, the right side of guide limiting stopper 212 forms the first screwed hole 213 of left and right directions；
The lower end of the right connection pedestal 22 forms the second clamping hole 221, and upper end forms and the phase of guide limiting stopper 212
The guide and limit groove 222 of cooperation, the sleeve of guide limiting stopper 212 in guide and limit groove 222, it is described it is left connection pedestal 21 and right company
Pedestal 22 is connect to be fixedly connected by two the first bolts 23；Through hole 223 is formed on the right side wall of the guide and limit groove 222；
Six roads circumferentially spaced 60 are formed on the inwall in the first clamping hole 211 and second clamping hole 221
The keyway 220 of degree, the road keyways 220 of the first clamping 211 Shang of hole six and the second clamping road keyways 220 of 221 Shang of hole six symmetrically set
Put.
Furthermore, the upper end of the connecting portion 12 forms the second screwed hole 121 of left and right directions, the connection
The left and right sides in portion 12 forms a telescopic 122 in bar shape being coaxially set with the second screwed hole 121 respectively, described
The telescopic 122 in left side is socketed in the first clamping hole 211, and the telescopic 122 on right side is socketed in the second clamping hole 221；Institute
The inside for stating telescopic 122 forms the bellmouth 123 and pilot hole 124 for communicating, the phase of 124 and second screwed hole of pilot hole 121
It is logical；The uniform open slot 125 in six roads is formed on the telescopic 122, six roads are formed on the outer wall of telescopic 122 circumferentially
Direction is spaced 60 degree of raised rectangular strip 126, and the sleeve of the rectangular strip 126 is in keyway 220.
Furthermore, integrally formed pull bar 13 is socketed with the telescopic 122, the pull bar 13 includes head
Round platform 131, middle part guide post 132 and the screw rod 133 of afterbody, the round platform 131 is pressed against on the inwall of bellmouth 123,
Guide post 132 is slidably connected with pilot hole 124, and screw rod 133 is screwed onto in the second screwed hole 121.
Furthermore, the spring 3 is fixed on the right side wall of guide and limit groove 222, the spring 3 and through hole
233 are coaxially set, and the second bolt 24 is socketed with the through hole 233, and the second bolt 24 is screwed onto the first screw thread through spring 3
In hole 213.
Operation principle：First, due to six road rectangular strips 126 and six circumference uniform distributions of keyway 220, different socket modes can
Realize the connection of bucket tooth 1 and the different angles of toothholder 2；Second, the first clamping hole 211 of left connection pedestal 21 is socketed in left side
On telescopic 122, rectangular strip 126 is socketed in keyway 220；3rd, it is directed to stopper slot 222 and is enclosed within guide limiting stopper 212,
