[0002] Angle grinder, also known as grinding machine or disc grinder, is a kind of grinding tool used for cutting and grinding fiberglass. It is a portable electric tool that uses fiberglass for cutting and grinding. It is mainly used for cutting, grinding and brushing metal and stone, etc. It has many uses and is often used by carpenters, bricklayers, and welders. Common models of angle grinders are divided into 100 mm (4 inches), 125 mm (5 inches), 150 mm (6 inches), 180 mm (7 inches) and 230 mm (9 inches) according to the specifications of the accessories used. The small-sized angle grinders used in Europe and the United States are 115 mm electric angle grinders, which use high-speed rotating thin-sheet grinding wheels, rubber grinding wheels, wire wheels, etc. to grind, cut, rust and polish metal components. Water cannot be used when operating an angle grinder, and a guide plate must be used when cutting stone. For models equipped with electronic control devices, if suitable accessories are installed on such machines, grinding and polishing operations can also be performed.

[0003] The existing angle grinder is provided with a handle, which makes it convenient for workers to operate, but the position of the handle is fixed. Since everyone has different usage habits, it may cause trouble to the operator when using this angle grinder, reducing work efficiency. Therefore, we propose an angle grinder for construction engineering, which can adjust the position of the handle to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0022] refer to Figures 1 to 5 The utility model provides an angle grinder for construction engineering, including an angle grinder body 1 and a handle 3. A strip-shaped connecting block 4 is fixedly provided on the side wall of the angle grinder body 1. The handle 3 is connected to the connecting block 4 through an adjusting mechanism 2. The adjusting mechanism 2 includes a groove 201, a threaded rod 202, a first limiting rod 203 and a slider 204. The groove 201 is arranged on a side of the connecting block 4 away from the angle grinder body 1. Both ends of the threaded rod 202 are rotatably connected to both ends of the inner wall of the groove 201, and one end passes through the connecting block 4. Both ends of the first limiting rod 203 are fixedly connected to both ends of the inner wall of the groove 201. The slider 204 is threadedly connected to the threaded rod 202 and slidably connected to the first limiting rod 203. The handle 3 is arranged on a side of the slider 204 away from the angle grinder body 1.

[0023] During the use of the present invention, if the position of the handle 2 needs to be adjusted, the threaded rod 202 needs to be rotated first, so that the slider 204 moves in the groove 201 along the first limiting rod 203 under the drive of the threaded rod 204, thereby driving the position of the handle 3 to change until it is adjusted to a position that the operator feels comfortable, and then the subsequent process can be carried out.

[0024] In order to be able to fold the handle 3 when not in use, as an improvement of the technical solution, a fixed seat 5 is provided on the side of the slider 204 away from the grinder body 1, and a groove is provided on the side of the fixed seat 5 away from the slider 204. A mounting seat 6 is fixedly provided on the side of the handle 3 close to the fixed seat 5, and the mounting seat 6 is rotatably connected in the groove of the fixed seat 5.

[0025] When in use, the handle 3 is rotated to be nearly perpendicular to the angle grinder body 1 . When not in use, the handle 3 is rotated to be nearly parallel to the angle grinder body 1 for easy storage.

[0026] In order to prevent the handle 3 from rotating when in use, as an improvement, a second rotating shaft 7 is fixedly arranged in the slot of the fixing seat 5, the mounting seat 6 is rotatably connected to the second rotating shaft 7, and a limiting mechanism 8 is further arranged between the fixing seat 5 and the mounting seat 6. The limiting mechanism 8 fixes the position of the handle 3 when in use or after being stored.

[0027] As a specific implementation method of the limiting mechanism 8, the limiting mechanism 8 includes two second limiting rods 801, and two sliding grooves penetrating into the slot are provided on the upper surface of the fixed seat 5. A fixing ring 803 is provided on each second limiting rod 801, and the fixing ring 803 can slide up and down in the sliding groove, and a spring 804 is sleeved on each second limiting rod 801, one end of the spring 804 is connected to the fixing ring 803, and the other end is connected to the inner wall of the upper end of the sliding groove. The upper ends of the two second limiting rods 801 are connected by a handle 9, and a limiting hole 805 is provided on the mounting seat 6.

[0028] During normal use, the two springs 804 are in a natural state. In this case, the lower end of a second limiting rod 801 is inserted into the limiting hole 805 to limit the position of the handle 3. When it is not in use and needs to be stored, the handle 9 is held and lifted upward, and the handle 9 drives the second limiting rod 801 to slide upward, and the second limiting rod 801 drives the fixing ring 803 to slide upward along the slide groove 802, and the fixing ring 803 compresses the spring 804 until the second limiting rod 801 is completely removed from the limiting groove 805, and then the handle 3 can be turned to be close to the angle grinder body 1, and then the handle 9 is released, and the spring 804 is reset, thereby driving the other second limiting rod 801 to be inserted into the limiting groove 805 to limit the handle 3, so as to facilitate the storage of the handle 3 and the carrying or transportation of the angle grinder body 1. In both states, one of the two second limiting rods 801 is always in the limiting groove 805, and the position of the other will not conflict with the mounting seat 6.

[0029] In order to facilitate the rotation of the threaded rod 202 , as an improvement of the technical solution, after the threaded rod 202 extends from the connecting block 4 , it is fixedly connected to the first rotating shaft 205 , and a knob 206 is fixedly disposed at one end of the first rotating shaft 205 away from the connecting block 4 .

[0030] When the position of the handle 3 needs to be adjusted, the knob 206 is rotated to drive the first rotating shaft 205 to rotate, and the first rotating shaft 205 drives the threaded rod 202 to rotate, thereby changing the position of the slider 204 .

[0031] As a specific rotational connection method, two ends of the threaded rod 202 are rotationally connected to two ends of the inner wall of the groove 201 through bearings.

[0032] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
