[0018] As Figures 1-3 shown:

[0019] This embodiment provides a portable and adjustable profile grinding device, including an angle grinder main body 1, and further including an installation frame 2 for installing the angle grinder main body 1. The installation frame 2 includes a fixed frame structure 21 and a handheld frame structure 22. A connecting frame structure 23 is rotatably connected between the fixed frame structure 21 and the handheld frame structure 22. The fixed frame structure 21 includes a support bottom plate 211. At both ends of the upper base surface of the support bottom plate 211, support vertical plates 212 are symmetrically fixed, and clamping plate assemblies 213 that slide horizontally are installed on both support vertical plates 212. Corresponding guide slideways 2111 are opened on the corresponding support bottom plate 211. The clamping plate assembly 213 includes an arc-shaped plate body 2131 slidably arranged in the slideway. A rotating connection seat 2132 is fixedly installed on the outer arc surface of the arc-shaped plate body 2131. An adjusting screw rod 2133 is rotatably connected to the rotating connection seat 2132. A threaded hole 2121 corresponding to the adjusting screw rod 2133 is opened on the support vertical plate 212;

[0020] During use, the installation frame 2 is used to install and fix the angle grinder main body 1, that is, the adjusting screw rods 2133 rotating on the two support vertical plates 212 can drive the arc-shaped plate body 2131 to slide along the guide slideway 2111 on the support base, so that the arc-shaped plate body 2131 can clamp and fix the angle grinder main body 1 for installation.

[0021] As Figure 1 shown, the handheld frame structure 22 includes a handheld rod 221 hinged to the working end of the angle grinder main body 1. An articulated seat 222 for hinging is provided at this end of the handheld rod 221. One end of the corresponding articulated seat 222 is fixedly connected to the angle grinder main body 1, and the other end is fixedly connected to the end of the handheld rod 221;

[0022] During use, the handheld rod 221 is used to be held by the operator, so it can be used as an extension function, avoiding the problems of the operator bending down and being too close to the grinding position during grinding.

[0023] As Figure 1 , 2As shown, a handgrip 223 is provided at the other end of the handheld rod 221. In addition, the handheld rod 221 can be set as a telescopic type to facilitate adjusting the length to adapt to operators of different heights and postures for operation. The handgrip 223 is fixed to the end of the handheld rod 221 through a fastener, facilitating the operator to hold it.

[0024] As Figure 1 , 3 shown, the connecting frame structure 23 includes a slider sleeve 231 sleeved on the handheld rod 221. A strip-shaped hole 2311 is formed in the corresponding slider sleeve 231. A cylindrical sleeve 232 is further fixed at the lower end of the slider sleeve 231. A sliding rod 233 is arranged in the cylindrical sleeve 232. Connecting rods 234 are symmetrically installed at both ends of the sliding rod 233. A shaft hole 2341 is formed at the other end of the connecting rod 234. A shaft-shaped protrusion 235 is arranged in the shaft hole 2341. A limiting block 236 is fixed to the other side base surface of the shaft-shaped protrusion 235. One side base surface of the limiting block 236 is attached to the side base surface of the support bottom plate 211. A support rod 237 is arranged between the two limiting blocks 236. A block-shaped protrusion 2112 should be arranged on the corresponding side base surface of the support bottom plate 211. An installation hole 2113 matching the support rod 237 is formed in the corresponding block-shaped protrusion 2112. The handheld rod 221 is arranged through the strip-shaped hole 2311. When an upward force is applied to one end of the handgrip 223 of the handheld rod 221, the handheld rod 221 has a certain movement space in the strip-shaped hole 2311, which is more convenient for applying a downward pressure to the angle grinder main body 1 at the other end of the handheld rod 221, facilitating more powerful grinding. In addition, the support rod 237 and the sliding rod 233 can ensure that the fixed frame structure 21 and the handheld frame structure 22 slide relative to the connecting frame structure 23, thereby reserving the movement space when the connecting frame structure 23 needs to be modified subsequently.

[0025] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0026] The above is the preferred embodiment of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle described in the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
