Description

Technical Field

[0001] The utility model relates to an angle grinder, in particular to an angle grinder with adjustable angle. Background Art

[0002] An angle grinder is an electric tool generally used for processing metal, wood and other materials. An angle grinder is usually composed of an electric motor, a grinding disc, a guard and a handle. When in use, the motor drives the grinding disc to rotate at high speed, thereby enabling the grinding disc to grind or cut the material.

[0003] In the existing technology, there is an easy-to-use angle grinder with publication number CN213164704U, which includes a casing, a grinding head connected to the upper end of the casing, a motor assembly located inside the casing and a battery pack connected to the lower end of the casing, the grinding head is transmission-connected to the motor assembly, the battery pack is electrically connected to the motor assembly, the casing includes an upper casing and a lower casing, the upper casing and the lower casing are rotatably connected, and the rotation angle is 0-180 degrees, the grinding head is fixed at the upper end of the upper casing, the motor assembly is located in the upper casing, and the battery pack is fixed at the lower end of the lower casing, so that the angle between the grinding head and the casing can be changed by adjusting the rotation angle of the upper casing and the lower casing.

[0004] However, it still has some shortcomings. For example, when the angle grinder is in use, the body of the angle grinder will vibrate, and the locking rod used to limit the upper casing is prone to shaking due to the vibration, so the locking rod is prone to breakage from the lock button. If the locking rod is broken, the upper casing cannot be limited and the upper casing rotates. In this case, the grinding head installed on the upper casing will also rotate with the rotation of the upper casing, which can easily cause injury to the user of the angle grinder. Utility Model Content

[0025] The following will refer to the drawings to describe in detail the preferred embodiments of the present utility model. Those skilled in the art will understand that these descriptions are only descriptive and exemplary, and should not be construed as limiting the protection scope of the present utility model.

[0026] It should be noted that: Similar reference numerals represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it may not be further defined and explained in subsequent drawings.

[0027] This embodiment mainly elaborates on the structure of an angle grinder with adjustable angle, specifically as follows:

[0028] Such as Figures 1-8As shown, an angle grinder with adjustable angle includes a first housing 1, a second housing 2 and a third housing 3. After the first housing 1 and the second housing 2 are enclosed, they are rotatably connected to the third housing 3. A spring seat 5 is arranged in the first housing 1, a second mounting seat 51 is arranged on the spring seat 5, a spring 6 is arranged in the second mounting seat 51, and the bottom of the spring 6 is in interference fit with the second mounting seat 51. A lock button 4 is arranged in the enclosed first housing 1 and second housing 2. The lock button 4 limits the third housing 3 by cooperating with the spring 6. The lock button 4 includes a lock rod 41 and a first mounting seat 42. The first mounting seat 42 is located in the lock button 4, and the first mounting seat 42 is in interference fit with the top of the spring. A first limiting block 11 is arranged in the first housing 1, and a second limiting block 10 is arranged in the second housing 2. When the first housing 1 and the second housing 2 are enclosed, the first limiting block 11 in the first housing 1 and the second limiting block 10 in the second housing 2 are in contact with the lock rod 41, which can make the lock rod 41 more stable in the first housing 1 and the second housing 2, so that the lock rod 41 can be prevented from shaking due to vibration, thereby reducing the problem of fracture between the lock rod 41 and the lock button 4. At the same time, the reliability of the lock rod 41 to limit the third housing 3 is improved, and further the use safety of the angle grinder is improved. Among them, the settings of the first mounting seat 42 and the second mounting seat 51 facilitate the installation of the spring 6, and the interference fit between the first mounting seat 42 and the second mounting seat 51 and the spring 6 can make the spring 6 not easy to fall off, so that the reliability of the lock button 4 to limit the third housing 3 is improved.

[0029] Further, a first support block 7 and a second support block 9 are respectively arranged in the first housing 1 and the second housing 2. When the first housing 1 and the second housing 2 are enclosed, the first support block 7 and the second support block 9 are in contact with each other. In this way, the settings of the first support block 7 and the second support block 9 can improve the strength of the first housing 1 and the second housing 2 after being enclosed, and further improve the body strength of the angle grinder.

[0030] Further, anti-slip layers 8 are arranged on the surfaces of the first housing 1 and the second housing 2. In this way, when the user uses the angle grinder, the problem of the angle grinder slipping from the user's hand is reduced.

[0031] A connecting column 43 is arranged on the lock button 4, and a connecting groove 413 is arranged on the lock rod 41. The lock button 4 is connected to the lock rod 41 through the cooperation of the connecting column 43 and the connecting groove 413. In this way, when the lock button 4 or the lock rod 41 is damaged, it can be replaced separately, which reduces the waste of resources. And a plurality of friction rings 431 are arranged on the connecting column 43 of the lock rod 41, and the friction rings 431 are all in close fit with the inner wall of the connecting groove 413. In this way, the firmness of the connection between the connecting column 43 and the connecting groove 413 can be improved.

[0032] Further, an installation cavity 412 is formed in the locking lever 41, and a reinforcing block 411 is arranged in the installation cavity 412. In this way, the arrangement of the installation cavity 412 can reduce the weight of the locking lever 41, so that the locking button 4 can be more flexible, and the arrangement of the reinforcing block 411 can ensure the strength of the locking lever 41.

[0033] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the present invention is usually placed during use. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0034] The above has introduced in detail the angle-adjustable angle grinder provided by the present invention. Specific examples are used in this article to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the present invention and its core idea. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and modifications can still be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
