Technical Field

[0001] The utility model relates to the technical field of safety devices, in particular to a clamping device for an angle grinder. Background Art

[0002] Angle grinder is a tool that uses a high-speed rotating thin-blade grinding wheel, rubber grinding wheel, wire wheel, etc. for cutting and grinding. Angle grinders can be handheld and easy to move. Compared with fixed electric saws or grinders, they are more flexible and are widely used in grinding, rust removal, polishing and other processing of metal components, stone and other materials.

[0003] The structure of the angle grinder includes a rotating part at the top and a gripping part at the rear end. A trigger and a fixing part are provided on the gripping part. The trigger can be pressed to start operation and released to stop operation. The fixing part can also be adjusted to maintain the trigger in a pressed state so that the angle grinder continues to run. Handle screw holes are provided on both sides of the angle grinder. In order to facilitate force during use, the angle grinder handle can be installed on the handle screw holes. The staff holds the gripping part with one hand and the angle grinder handle with the other hand to work.

[0004] However, when using an angle grinder, there are many potential safety hazards due to the close hand-held distance, such as the grinding wheel breaking due to excessive rotation speed or collision, the generation of debris and sparks during cutting and grinding, and the smoke and noise generated by grinding, which may threaten the safety of the operator. In addition, the angle grinder is difficult to reach high places or corners when in use, which is inconvenient to operate. Utility Model Content

[0006] The technical solution of the utility model is:

[0007] A clamping device for an angle grinder comprises a clamping base, two ends of the clamping base are oppositely provided with clamping plates, the clamping plates are provided with connecting holes, and the hole diameter of the connecting hole is greater than or equal to the hole diameter of the screw hole of the angle grinder handle;

[0008] It also includes a first gripping rod, which is detachably connected to the clamping base;

[0009] It also includes a locking screw, which is used to pass through the connecting hole and be threadedly connected with the screw hole of the angle grinder handle.

[0010] Furthermore, it also includes at least one secondary grip rod, and at least one secondary grip rod is connected to the first grip rod and to each other through threads. The secondary grip rod can be connected to the first grip rod or other secondary grip rods to adjust the length of the clamping device.

[0011] Furthermore, the first grip and the secondary grip are both provided with anti-skid patterns, which can prevent the first grip or the secondary grip from slipping during the gripping process, thereby improving safety.

[0012] Furthermore, the first grip and the secondary grip are made of hard metal.

[0013] Furthermore, a first base thread is provided at one end of the first grip rod, and threaded holes are respectively provided on two adjacent sides of the clamping base where no clamping plate is provided. The threaded holes are adapted to the first base thread, and the first base thread of the first grip rod can be connected to any threaded hole to expand the connection angle.

[0014] Furthermore, it also includes an angle adjustment rod, which includes a first adjustment rod and a second adjustment rod. The first adjustment rod and the second adjustment rod are connected by a rotating shaft. The end of the first adjustment rod that is not connected to the rotating shaft is detachably connected to the clamping base, and the end of the second adjustment rod that is not connected to the rotating shaft is detachably connected to the first grip rod. The angle can be adjusted by the angle adjustment rod, making the application of the angle grinder more flexible.

[0015] The beneficial effects of the utility model are:

[0016] The angle grinder clamping device provided by the utility model adopts a locking screw to fix the clamping base on the angle grinder, and the clamping base is connected to the first holding rod through the first base screw hole. After installation, it does not affect the original performance and function of the angle grinder, can extend the holding distance of the angle grinder, and prevent the grinding wheel from breaking, debris or sparks from flying during the use of the angle grinder to injure the operator; the angle grinder can be extended to a high place or a narrow position for operation, so that the use scenario of the angle grinder is more flexible and the operability is improved; the angle grinder clamping device can adjust the installation angle by adjusting the locking screw, and is easy to install and disassemble, has a simple structure, is easy to produce, and is conducive to promotion.
