[0024] like Figure 1-3 As shown, the utility model proposes a steel angle grinder, including an angle grinder body 4, an angle grinder head 2 and a grinding wheel 6, the angle grinder head 2 is arranged at the left end of the angle grinder body 4, the output shaft of the angle grinder head 2 is coaxially connected with the grinding wheel 6, and it also includes a handle 301, a protective component 1 is sleeved on the outside of the grinding wheel 6, and the outer end surface of the angle grinder head 2 is connected to the handle 301 through an adjustment mechanism 3.

[0025] In the utility model, by starting the switch on the angle grinder body 4, the grinding wheel 6 can be driven to rotate through the angle grinder head 2, so that the steel can be grinded; and through the adjustment mechanism 3, the handle 301 can be driven to move, so that the staff can achieve the best operating posture and angle when grinding, thereby improving the convenience of operation and reducing the operation risk.

[0026] The adjustment mechanism 3 includes a limiting mechanism and a limiting member 307 , which are connected to the limiting member 307 and installed on the outer end surface of the angle grinder head 2 , the movable end of the limiting mechanism is connected to the handle 301 , and the limiting end of the limiting mechanism is connected to the limiting member 307 .

[0027] It should be noted that by adjusting the limiting mechanism, the handle 301 can be driven to rotate along the limiting mechanism, and then the limiting mechanism is limited by the limiting member 307 .

[0028] In an optional embodiment, the limiting mechanism includes a sliding ring 304, a slider 302, a connecting plate 306 and a limiting assembly 305. The sliding ring 304 is installed on the outer end surface of the angle grinder head 2. A sliding groove 303 is provided on the outer end surface of the sliding ring 304. The slider 302 is slidably connected to the sliding groove 303. The outer end surface of the slider 302 is connected to the handle 301. The connecting plate 306 is arranged on the outer end surface of the slider 302 and is located outside the limiting member 307. The limiting assembly 305 is arranged on the side of the connecting plate 306 away from the limiting member 307. The limiting member 307 includes a limiting hole 3071 and a mounting ring 3072.

The number of the limiting holes 3071 is multiple and distributed in a circular array on the outer end surface of the mounting ring 3072.

[0029] It should be noted that by pulling the limit assembly 305, the limit end of the limit assembly 305 is pulled out from the limit hole 3071, and then the slider 302 is driven by the handle 301 to rotate along the slide groove 303 to adjust the position of the handle 301. After the adjusted position is determined, the limit assembly 305 is released, so that the limit end of the limit assembly 305 is inserted into the inside of the limit hole 3071, so that the handle 301 can be limited.

[0030] In an optional embodiment, the limit assembly 305 includes a handle 3051, a spring 3052, a limit shell 3053, a limit ring 3054 and a limit rod 3055. The limit shell 3053 is arranged on the outer end surface of the connecting plate 306. One end of the limit rod 3055 passes through the outer end surface of the limit shell 3053 and is connected to the handle 3051. The other end of the limit rod 3055 passes through the connecting plate 306. The spring 3052 is sleeved on the outer end surface of the limit rod 3055.

[0031] It should be noted that by pulling the handle 3051, the handle 3051 can drive the limiting ring 3054 to move upward, causing the spring 3052 to contract. At this time, the bottom of the limiting rod 3055 will not be inserted into the limiting hole 3071. After adjusting the position of the handle 301, the handle 3051 is released to expand the spring 3052, thereby driving the limiting rod 3055 to descend through the limiting ring 3054 and descend to the inside of the limiting hole 3071, thereby limiting the handle 301.

[0032] In an optional embodiment, a protective cover 5 is provided on the grip of the angle grinder body 4 .

[0033] It should be noted that the protective cover 5 can improve the comfort of the worker holding the angle grinder body 4.

[0034] In an optional embodiment, the protective component 1 includes a first protective cover 101 and a second protective cover 102. The second protective cover 102 is arranged at the lower end of the angle grinder head 2, and the grinding wheel 6 is located inside the second protective cover 102.
