The invention discloses an automatic pay-off grass mowing head free of cover disassembly and capable of feeding a wire, which comprises a fixed seat, a pay-off sliding block is in sliding fit in the fixed seat, and the pay-off sliding block rotates along with the grass mowing head and can form different states according to the rotating speed and the centrifugal force so as to realize pay-off control; a pay-off spring is arranged at the first end of the pay-off sliding block, and when the grass trimming head rotates to reach a set value, the pay-off sliding block compresses the pay-off spring to the shortest length; the pay-off device is characterized in that the pay-off device further comprises a reel rotationally arranged on the fixed seat, wire outlet blocks are arranged on the two sides of the fixed seat, the reel is limited on the fixed seat through a buckling cover, the buckling cover is buckled with the fixed seat, and the wire outlet blocks are arranged on the two sides of the fixed seat. And the upper end of the reel extends out of the fastening cover.
Description
technical field [0001] The invention relates to the technical field of garden tools, in particular to an automatic line pay-off and grass trimming head that can enter the line without removing the cover. Background technique [0002] A lawnmower is a garden tool used to mow lawns. At present, rotary lawn mowers mainly use a grass rope made of fine nylon as a cutting device. When using the grass cutting rope as a cutting device, it often involves the problem of paying off the grass cutting rope. The general grass cutting rope pay-off mechanism adopts manual pay-off. Each time the pay-off button is pressed, the rope end is pulled out once. This pay-off method It needs to be carried out when the lawn mower is stopped, which is troublesome to operate and very inconvenient to use. [0003] Therefore, more and more manufacturers have introduced automatic line pay-off and grass cutting heads to overcome the problem of needing to manually control the line out. [0004] Under the ...
