[0012] Preferably, the top of the scraper body is provided with an installation groove, and a fixing plate is fixedly installed on the top of the scraper body, and the fixing plate is provided with threaded holes.

[0013] Preferably, the lifting mechanism includes a bearing, a rotating hole is provided on the U-shaped seat, the bearing is fixedly installed in the rotating hole, and a screw is fixedly installed on the inner ring of the bearing, with the screw threadedly connected to the threaded hole.

[0014] Preferably, a rotating block is fixedly installed on the top of the screw, and a vertical hole is opened on the top cover. One end of the screw passes through the vertical hole and the rectangular sliding hole.

[0015] Preferably, the locking mechanism includes two locking blocks, and the inner walls of the two rotating holes are provided with connecting holes. The two locking blocks are slidably installed in the two connecting holes respectively, and one end of the two locking blocks is respectively engaged with the two corresponding locking slots.

[0016] Preferably, the other end of the two locking blocks is fixedly installed with the same U-shaped plate, the U-shaped plate is located on one side of the U-shaped seat, and the U-shaped plate is provided with protrusions.

[0017] Preferably, two reset slots are provided on one side of the U-shaped seat, and a reset block is slidably installed in each of the two reset slots. One side of each of the two reset blocks is fixedly connected to the U-shaped plate.

[0019] Compared with the prior art, the advantages of this utility model are:

[0020] This solution uses a rotating block to drive the screw to rotate, causing the fixed plate, which is threadedly connected to the screw, to move vertically. The fixed plate then drives the scraper body to slide within a rectangular sliding hole, adjusting the overall length to meet different usage needs. When shortened to its shortest length, it is easy to carry.

[0021] By pulling the U-shaped plate away from the U-shaped seat by the protruding block, the locking block is disengaged from the locking groove, releasing the fixation of the two rotating shafts. At this time, the handle can be rotated through the two rotating shafts, thereby adjusting the angle of the handle. After adjustment, the two locking blocks are locked into the corresponding two locking grooves, and the two rotating shafts are locked again.

[0022] This invention allows for easy adjustment of the overall length and the angle of the handle to meet different usage needs. Attached Figure Description
