DETAILED DESCRIPTION
[0017] In order to clearly illustrate the technical features of the scheme, the scheme will be described below through specific embodiments.
[0018] For example, Figs. 1-2As shown, this utility model includes a base 1 with wheels, a square column 2 vertically mounted on the top surface of the base 1 and rotatably connected to the base 1, and an upper sliding sleeve 4 and a lower sliding sleeve 3 that can slide up and down sequentially on the square column 2 from top to bottom. The lower sliding sleeve 3 is provided with fasteners for tightening the square column 2 and achieving positioning. One end of a handle 5 is hinged to the lower sliding sleeve 3. A horizontally arranged telescopic arm is mounted on the upper sliding sleeve 4. The telescopic arm includes a fixed square tube 7 and a movable square tube 9 that is inserted into the fixed square tube 7 and can be pulled along the fixed square tube 7. The end of the fixed square tube 7 away from the movable square tube 9 is fixed to the upper sliding sleeve 4, and the end of the movable square tube 9 is provided with a mounting base for an electric wrench. One end of a connecting rod 6 is hinged to the fixed square tube 7, and the other end is hinged to the handle 5.
[0019] In this embodiment, the fastener is a fastening bolt 11, which is threadedly connected to the sliding sleeve 3. By rotating the fastening bolt 11, the square column 2 can be tightened, thereby positioning the sliding sleeve 3. The tightness adjustment of the fastening bolt 11 allows the sliding sleeve 3 to be adjusted up and down along the square column 2.
[0020] In this embodiment, to position the movable square tube 9, a tightening bolt 8 is threaded onto the fixed square tube 7 to tighten the movable square tube 9. The movable square tube 9 can be pulled out and adjusted, thereby realizing the telescopic arm's telescopic adjustment.
