Problems solved by technology

[0003] In industrial production, rust is relatively common. After the accumulated metal raw materials or metal semi-finished products are shelved for a period of time, due to the large water vapor in the factory, the metal is extremely prone to rust. Rusty metal raw materials or metal semi-finished products affect the molding quality of the product. , a waste of raw materials, in order to remove the rust in time, people often use sandpaper for grinding, or use a more efficient electric grinder
[0004] Most of the existing grinders are angle grinders. Due to structural reasons, this kind of grinder needs to be inclined at a certain angle when used. Therefore, the metal contact surface is small, that is, the grinding surface is small. For the structure with texture on the surface, this It is difficult for this kind of polishing machine to grind deeply along the texture, while the polishing machine with circular motion can easily smooth the texture when polishing

Abstract

The invention relates to a grinding paper clamp rod of a swinging arm type handheld grinding machine. The grinding paper clamp rod comprises a longitudinal trapezoidal groove which is formed in the upper end face of the grinding paper clamp rod, wherein a trapezoidal strip is arranged in the trapezoidal groove; a locating notch is formed in each of the left and right sides of the lower end of the trapezoidal strip; a stepped hole is formed in the rear end of the grinding paper clamp rod, a spring is arranged in the stepped hole, a button is connected into the spring, turning sheets are respectively connected to the left and right sides of the upper end of the button, strip-shaped holes I are respectively formed in the junctions between the turning sheets and the button, the middle parts of the turning sheets are respectively connected to the internal wall of the rear end of the trapezoidal groove, strip-shaped holes II are respectively formed in the other ends of the turning sheets and are respectively connected with locating columns, and guiding rails which are used for limiting the locating columns to vertical linear movement are arranged at the upper parts of the locating columns. According to the grinding paper clamp rod of the swinging arm type handheld grinding machine, the trapezoidal strip is snapped into the trapezoidal groove, the upper edge of the trapezoidal groove is of an acute angle, and the frictional force between grinding paper and the interior of the trapezoidal groove is enormous after the two edges of the grinding paper bypass the upper edge of the trapezoidal groove and are snapped into the trapezoidal groove, so that the grinding paper difficultly falls out of the trapezoidal groove, and the stability of clamping of the grinding paper is guaranteed.

Description

technical field [0001] The invention relates to the technical field of grinding equipment, in particular to a sandpaper clamping rod for a swing-arm type hand-held grinding machine. Background technique [0002] Rust is the most common form of metal wear and tear, as long as there is oxygen and water, it is accompanied by metal all the time, especially the most commonly used metal by human beings—iron. Rust is a brownish-red substance that is not as hard as iron , It is easy to fall off. After a piece of iron is completely rusted, its volume can expand by 8 times. If the rust is not removed in time, the iron in the rust will rust faster because the spongy rust is particularly easy to absorb water. [0003] In industrial production, rust is relatively common. After the accumulated metal raw materials or metal semi-finished products are shelved for a period of time, due to the large water vapor in the factory, the metal is extremely prone to rust. Rusty metal raw materials or...
