The collecting assembly 9 comprises a second guide rod 901, a seventh spring 902, a fixed frame 903, an eighth spring 904, a connecting frame 905, a second push rod 906, a collecting plate 907 and wedge blocks 908, the second guide rod 901 is arranged on the inner side of the top of the support frame 1, the fixed frames 903 are arranged on the front side and the rear side of the middle of the second guide rod 901 in a sliding manner, the seventh spring 902 is connected between the fixed frame 903 and the second guide rod 901, the seventh spring 902 is sleeved on the second guide rod 901, the connecting frames 905 are arranged on the front side and the rear side of the fixed frame 903 in a sliding manner, the connecting frame 905 is matched with the fixed frame 903, the eighth spring 904 is connected between the upper part of the connecting frame 905 and the upper part of the fixed frame 903, the eighth springs 904 are respectively sleeved on the front side and the rear side of the upper part of the fixed frame 903, the second push rod 906 is arranged on the lower part of the inner side of the connecting frame 905, the, the wedge blocks 908 are slidably engaged with the second push rods 906, respectively.

When one pulls the fixing frame 903 upwards, the seventh spring 902 is compressed, the fixing frame 903 drives the connecting frame 905 and the gathering plate 907 to move upwards, the connecting frame 905 drives the second push rod 906 to move upwards, when the second push rod 906 contacts the wedge 908, the second push rod 906 moves inward, the second push rod 906 drives the connection frame 905 and the collection plate 907 to move inward, the eighth spring 904 is compressed, under the action of the gathering plate 907, the built weeds and the broken grass can be collected and cleaned more conveniently, and when people loosen the fixed frame 903, due to the reset action of the seventh spring 902, the fixing frame 903 is driven to move downwards to be reset, the fixing frame 903 is driven to move downwards by the connecting frame 905 and the gathering plate 907, when the second push rod 906 is disengaged from the wedge 908, due to the reset function of the eighth spring 904, the second push rod 906 is driven to move outwards, and the second push rod 906 drives the connecting frame 905 and the collecting plate 907 to move outwards to reset.

Still including second chucking subassembly 10, second chucking subassembly 10 is including supporting shoe 1001, kelly 1002, ninth spring 1003, third connecting rod 1004 and guide block 1005, supporting shoe 1001 is equipped with to the side in the top of support frame 1, both sides slidingtype kelly 1002 that are equipped with in the front and back of supporting shoe 1001 upper portion, cooperate between kelly 1002 and fixed frame 903, all be connected with ninth spring 1003 between kelly 1002 and the supporting shoe 1001, ninth spring 1003 suit is respectively on kelly 1002, be equipped with third connecting rod 1004 between kelly 1002 left side, the side is equipped with guide block 1005 in the top of supporting shoe 1001, slidingtype cooperation between guide block 1005 and the third connecting rod 1004.

When fixed frame 903 rebound, can drive kelly 1002 to the left side removal, ninth spring 1003 is compressed, when fixed frame 903 continues the rebound and breaks away from with kelly 1002, because the reset action of ninth spring 1003, can drive kelly 1002 to the right side removal to reseing, kelly 1002 can block fixed frame 903 this moment and make it can not the rebound, make people need not draw the fixed frame 903 of post all the time, when people move third connecting rod 1004 left, third connecting rod 1004 can drive kelly 1002 and move left, ninth spring 1003 is compressed once more, when fixed frame 903 breaks away from with kelly 1002, fixed frame 903 can the rebound, when people loosen kelly 1002, because the reset action of ninth spring, can drive kelly 1003 to the right side removal to reseing.

The above-mentioned embodiments are merely preferred embodiments of the present invention, which are not intended to limit the scope of the present invention, and therefore, all equivalent changes made by the contents of the claims of the present invention should be included in the claims of the present invention.
