Description
STANDOFF PIN CAP TIGHTENING DEVICE TECHNICAL FIELD
The invention relates to the technical field of standoff pin tightening equipment, and specifically relates to a standoff pin cap tightening device.
BACKGROUND OF THE INVENTION
As a fixing member for fixing an advertising signboard and a sign, the standoff pin generally consists of round screws and nuts made of iron, aluminum alloy, copper, stainless steel, etc., and has a diameter of 10 mm to 40 mm, depending upon the size of the sign. In the prior art, there are two kinds of standoff pins: standoff pins with caps having smooth planes, which generally have a small diameter; and standoff pins having blind holes formed on the caps, which generally have a large diameter. In the prior art, for the standoff pins with caps having smooth planes, tightening tools having a diameter matched with the diameter of such standoff pins are used, such as wrenches, to clamp and rotate the caps, in order to rotate and tighten the standoff pins. For the standoff pins having blind holes formed on the caps, another tightening tool with tightening columns is used, in order to rotate and tighten the standoff pins by inserting the tightening columns into the blind hole. However, there are still some problems when using the two kinds of standoff pins. When both the two kinds of standoff pins are used, it is necessary to carry different tightening tools. Thus, it is inconvenient to carry tightening tools. Meanwhile, restricted by the volume and position of some advertisement signs, it may be possible to use both the two kinds of standoff pins. When mounting such advertisement signs, it may be needed to use the two kinds of tightening tools alternately. The operation is both complex and time-consuming.
SUMMARY OF THE INVENTION

The round through hole 2 is used for conveniently hanging the tightening device body 1 on a storage component, for example, a bracket. Multiple holding portions 3 are inward concavely formed on a circumferential sidewall of the tightening device body 1. There are 6 to 12 holding portions 3. The holding portions 3 are arranged in an arc shape, and the holding portions 3 are distributed on the circumferential sidewall of the tightening device body 1 in an annular array by using a centerline of the tightening device body 1 as the center of the array. An arc-shaped chamfer 9 is formed at a junction of two adjacent holding portions 3. A first fixed slot 4 is inward formed on a front end face and a second fixed slot 5 is formed on a rear end face of the tightening device body 1, and both the first fixed slot 4 and the second fixed slot 5 are round. The first fixed slot 4 and the second fixed slot 5 are arranged coaxially to the round through hole 2. The first fixed slot 4 has a diameter less than that of the second fixed slot 5. The diameter of the first fixed slot 4 and the second fixed slot 5 may be determined according to actual requirements, or they may be manufactured in a conventional size. A first fixation block 6 is arranged on a sidewall of the first fixation slot 4 and a second fixation block 7 is arranged on a sidewall of the second fixed slot 5. The first fixation block 6 or the second fixation block 7 can fix, together with the first fixation slot 4 or the second fixed slot 5, the standoff pin workpiece running into the first fixation slot 4 or the second fixed slot 5. Tightening columns 8 are provided in the tightening device body 1, the tightening columns 8 are symmetrically arranged in the tightening device body 1, and one end of each of the tightening columns 8 is outward protruded from the circumferential sidewall of the tightening device body 1.
