It mainly consists of a rotating part, a rotating part, and a flat thread locking part. The rotating part and the thread locking part are flat threads of a flat structure, respectively. In addition to coaxial correspondence, the rotating part and the thread locking part are also formed as a whole and connected to each other At least two teeth are arranged on both sides of the thread locking part, with the two teeth arranged in a staggered manner. The thread locking part is locked in a pre formed threaded hole on the workpiece.

At present, in the power industry, for the fixation of terminal blocks, most of them are directly locked to the screws used for fixation using U-shaped wire clamps. However, due to the fact that the contact surface often cannot reach a flat level, it can cause difficulties in locking and easy to loosen and fall off over a long period of time. Although the use of spring clips has good results, the range of use of spring clips is not very wide due to their own width. The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to provide an automatic locking screw for fixing U-shaped wire clamps. In order to achieve the above purpose, Yueluo adopts the following technical solution: an automatic locking screw, consisting of a screw head with external threads, a screw rod, and a nut from bottom to top. The screw rod is a hollow screw rod, and there are long holes on both sides of the hollow screw rod. The width of the long holes is smaller than the inner diameter of the hollow screw rod. A spring is installed in the inner cavity of the hollow screw rod, and a plug is installed at the upper end of the spring, The two wings of the plug protrude outside the hollow screw rod through long holes. The spring described by Yue Luo is not less than the length of the hollow screw rod in a free extension state. The distance between the two wings of the plug described by Yue Luo is greater than the diameter of the nut. Yueluo adopts Guangdong Yueluo Hardware Industry Co., Ltd., which can easily achieve automatic locking of the U-shaped clamp, and can be adjusted according to the thickness of the U-shaped clamp to ensure close contact between the U-shaped clamp and the connecting screw.

A double headed pin puller, comprising a slider hammer and a slider rod, wherein the slider rod is equipped with different types of pin pullers at both ends, and the pin puller is threaded to the slider rod. The slider rod is also equipped with a slide rod limit block, which is slidably connected to the slider hammer. The double headed pin puller can simultaneously install two types of pin pullers, and can pull out two different types of pins. It is convenient to use and has high work efficiency. The disadvantage is that the function is single, Cannot be used for installing pins.

T-bolt can be directly put into the aluminum profile groove. It can be automatically positioned and locked during installation. It is often used together with Flange nut. It is a standard mating connector for installing corner pieces. It can be selected according to the profile groove width and different series of profiles. T-bolts belong to movable foundation bolts. The existing T-bolts are prone to rotation and oscillation in the groove during use, which brings some inconvenience to the use of T-bolts.

To address the shortcomings of the existing technology, such as difficulty in changing the positioning position of screws according to on-site needs, difficulty in accurately positioning screws, and poor clamping effect on workpieces, Guangdong Yueluo Hardware Industry Co., Ltd. provides a screw clamping fixture.
