Claims

1. A protective cover structure for a brush cutter, comprising a support rod and a working head disposed at the end of the support rod, characterized in that, A protective cover that partially covers the working head is fixed on the support rod. The protective cover includes a main cover and an adjustable cover. The main cover is fixed on the support rod and has a vertically through movable groove. The adjustable cover can move up and down within the movable groove to be stored or unfolded downwards. The main cover and the adjusting cover together form multiple sets of limiting structures. Each set of limiting structures includes an upper limit block and a lower limit block formed on the side wall of the movable groove, and a first limit block, a second limit block, and a pressing plate formed on the adjusting cover. The upper limit block cooperates with the first limit block to house the adjusting cover in the movable groove. The lower limit block is used to support the second limit block upwards, providing support for the adjusted cover after release. The pressing plate is used to press down. By pressing the pressing plate and adjusting the adjusting cover up and down, the upper limit block and the first limit block are engaged or disengaged, thereby realizing the housing or release of the adjusting cover.

2. A protective hood structure for a brush cutter according to claim 1, characterized in that The movable groove has a left insertion groove, a middle insertion groove and a right insertion groove. The upper limit block is formed on the side wall of the left insertion groove, the lower limit block is formed on the side wall of the right insertion groove, and the pressing plate moves in the middle insertion groove.

3. A protective hood structure for a brush cutter according to claim 2, wherein The adjusting covers on both sides of the pressing plate are respectively provided with a first plug plate and a second plug plate. The first limiting block and the second limiting block are respectively formed on the side walls of the first plug plate and the second plug plate. The first plug plate and the second plug plate are respectively inserted into the left plug slot and the right plug slot.

4. A protective hood structure for a brush cutter according to claim 3, wherein A right insertion slot is separately provided at the center of the movable slot, and the second insertion plate, which is located at the center of the adjusting cover, is movable in the right insertion slot.

5. The protective hood structure for a brush cutter according to claim 2, wherein A limiting groove is provided on the side wall of the intermediate insertion slot, and a limiting step is formed on the top of the pressing plate. When the adjusting cover is raised, the limiting step can abut against the limiting groove.

6. The protective hood structure for a brush cutter according to claim 1, wherein The space between the pressing plate and the first plug-in plate, and between the pressing plate and the second plug-in plate, is hollowed out, and the pressing plate can be operated by tools or fingers.

7. The protective hood structure for a brush cutter according to claim 2, wherein The limiting structure has at least two sets, and the two sets of limiting structures are respectively set at the two sides of the protective cover. At least one set of the limiting structure has an insertion hole on the side wall of the middle insertion groove, and the insertion hole is used for inserting a tool to press the pressing plate.

8. The protective hood structure for a brush cutter according to claim 1, wherein The bottom of the upper limit block and the lower limit block, and the top of the first limit block and the second limit block are formed with guide slopes.

9. The protective hood structure for a brush cutter according to claim 3, wherein The second plug-in plate at the bottom of the second limiting block has a receiving groove for the lower limiting block to move. A guide slope is formed at the bottom of the receiving groove. Positioning plates are formed in the receiving groove, the left plug-in groove, and on the surface of the second plug-in plate.
