Because the positions of the upper ear plates 11 of different sized sticks 1 may have a large distance that is not achievable by merely adjusting the rotation angle of the pendulum mass 64 and the fixed position of the pendulum mass 64, it is necessary to solve this problem by changing the fixed position of the upper positioning assembly 6, so that a plurality of first fixed positions 22 can accommodate different sized sticks 1. At the same time as the position of the upper positioning component 6 is changed, the position of the upper centering positioning component 61 is also changed, so that the position of the supporting component 9 is correspondingly adjusted to protect the upper centering positioning component 61, and therefore, a second different fixing position 23 is required to fix the supporting component 9.

As shown in fig. 5, the front positioning assembly 3 includes a front supporting table 31 disposed at the front portion of the base 2, a front seat plate 32 movably disposed on the front supporting table 31, a front pressing plate 33 disposed at the upper portion of the front seat plate 32, and side baffles 34 disposed at the sides of the front seat plate 32, wherein the front seat plate 32 is provided with a plurality of second waist-shaped holes 321 extending back and forth, and the front seat plate 32 is connected to the front supporting table 31 by front fixing screws (not shown) passing through the second waist-shaped holes 321. The front part of the arm 1 is supported on the front support table 31, the upper part is pressed by the front pressing plate 33, the side of the arm is supported on the side baffle 34, the front pressing plate 33 can rotate around the vertical shaft, and the side baffle 34 can rotate around the horizontal shaft so as to avoid the feeding path of the arm 1. The second waist-shaped hole 321 allows the front pressure plate 33 and the side baffle 34 to adapt to the front and rear positions of the bucket rod 1 so as to ensure that the front pressure plate 33 and the side baffle 34 can properly contact the front part of the bucket rod 1.

What has been described above is merely some embodiments of the present utility model. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit of the utility model.
