Description

Technical Field

[0001] The utility model relates to the technical field of angle grinders, and particularly relates to a manual angle grinder for glue detection. Background Art

[0002] During the glue detection process, in order to ensure the accuracy of the detection, workers usually use a manual angle grinder to grind off the excess glue. At the same time, potential defects or problems can be exposed during the grinding process, helping the inspectors to detect the glue more accurately. The existing manual angle grinders usually consist of an angle grinder main body, a grinding disc, and a protective cover.

[0003] For example: The utility model with the application number CN201921979065.X discloses an angle grinder, which specifically includes a connection head and a machine body. The connection head is fixedly installed at one end of the machine body. One side inside the machine body is fixedly installed with a water storage tank, and one side at the bottom of the machine body is fixedly installed with a dust storage box. A rotating motor is fixedly installed inside the connection head, and a grinding wheel cover is fixedly installed on one side at the bottom of the connection head. The bottom end of the rotating shaft of the rotating motor is connected with a connecting shaft. The disclosed angle grinder of the utility model can adsorb the dust generated during grinding through the provided dust storage box and air suction port, avoiding the inhalation of tiny particles generated during grinding by workers. The operability of the angle grinder by workers is improved through the provided auxiliary handle and handle. When workers perform deep grinding, the temperature between the grinding wheel and the grinding object can be conveniently reduced through the provided water storage tank and water spray port, and at the same time, the friction during grinding is reduced, thereby facilitating the adjustment of the grinding angle and depth.

[0004] However, for the current traditional manual angle grinders, the protective covers of the existing manual angle grinders are usually designed in a semi-circular shape in order not to affect the normal grinding of the grinding disc. However, the semi-circular protective cover will expose a part of the grinding disc. When transporting or not using the manual angle grinder, if the exposed grinding disc collides, it is easy to damage the grinding disc. Subsequently, it also takes a certain amount of time to replace the grinding disc, delaying the progress of glue detection and being inconvenient to use. Summary of the Utility Model

[0005] In view of this, the present utility model provides a manual angle grinder for glue detection, which has a second protective cover capable of protecting the grinding disc when the manual angle grinder is not in use. In the initial state, the positions of the second protective cover and the first protective cover seal and protect the grinding disc. When using the angle grinder main body to grind the detected glue, as the operator holds the angle grinder main body and presses down the control block, the control block moves downward and squeezes the connecting spring. As the control block moves, it drives the control swing rod to swing. As the control swing rod swings, it drives the guiding slide block to move. During the movement of the guiding slide block, it drives the control rack to move. As the control rack moves, it drives the control gear to rotate. As the control gear rotates, it drives the mounting collar to rotate. During the rotation of the mounting collar, it drives the second protective cover to rotate, so that it rotates to the outside of the first protective cover to expose the grinding disc for grinding.
