The utility model discloses a photovoltaic support stand column installation device which is used for connecting a stand column with a ground pile after the stand column is turned over and comprises a connecting base detachably connected with the ground pile and a stand column turning mechanism arranged on the connecting base. The stand column overturning mechanism comprises a fixing support connected with the connecting base, a stand column overturning bracket hinged to the fixing support and used for fixing the stand column, and a driving assembly used for driving the stand column overturning bracket to rotate relative to the fixing support. According to the stand column overturning device, overturning is achieved by operating the driving assembly and pushing the stand column overturning bracket, after the stand column is overturned and erected, the stand column is erected on a ground pile to be fixed, only one worker is needed in the overturning process, labor is saved, and the problem that the stand column overturning and erecting efficiency is low is solved. In addition, large equipment such as a crane is not needed, so that the cost can be saved while the efficiency is improved.

This utility model discloses an adjustable metal button, belonging to the field of button technology. It includes a base, a lower housing on top of the base, and an upper housing fixedly connected to the top of the lower housing. Vertical grooves are formed on both outer walls of the upper housing, and horizontal grooves are evenly formed on the inner wall of one side of each vertical groove. A bottom groove is formed at the bottom of the horizontal groove, and a movable shaft is rotatably connected to the inner wall of one side of the bottom groove. A deflecting plate is fixedly connected to the movable shaft. A limit block is fixedly connected to the top of the deflecting plate on the side away from the movable shaft. Second springs are fixedly connected to both sides of the bottom of the deflecting plate, and the bottoms of the second springs are fixedly connected to the bottom of the bottom groove. This adjustable metal button, through the vertical grooves, horizontal grooves, and locking posts, allows for convenient adjustment of the button length, thus easily achieving adjustment of the button's tightness and effectively solving the problem of adjusting the tightness of traditional buttons.

The utility model discloses a kind of anti-drop reinforcing components for pipe sleeve connection, it is related to pipeline connection technical field, including connecting band and two interval setting live buckle ribbon;Every live buckle ribbon includes the band body and band head connected as a whole, and band body is strip-shaped;The both ends of connecting band are respectively provided with a collar, two collars and two band bodies one to one correspond, collar is sleeved on corresponding band body, and collar and corresponding band body can slide relatively;The outside of band body is provided with multiple ratchet teeth evenly arranged along the length direction of band body;Band head includes fixed body, lock tongue, horizontal pivot, permanent magnet and handle.In use, two live buckle ribbons are respectively tightly buckled on two pipes mutually sleeved, since two live buckle ribbons are connected by connecting band, pipe sleeve connection part can be prevented from falling off;Since the tightness of every live buckle ribbon is adjustable, and by handle to move lock tongue, it can contact tight state, live buckle ribbon is taken down and disassembled, convenient to use.

The turning-over auxiliary device convenient to wear comprises two waistcoat pieces used for covering the chest and the back of a wearer respectively, and the two waistcoat pieces are connected through shoulder straps. The connecting rings are fixed on the side edges of the waistcoat pieces; the connecting rope penetrates through the connecting ring and turns, and the track of the connecting rope forms a U shape; one end of the connecting rope is connected with the wearable waistcoat, the other end of the connecting rope is connected with the winding device, and the winding device reduces the distance between the two waistcoat pieces by winding and shortening the length of the connecting rope. Therefore, the overall tightness is adjustable, and the patient is not easy to hurt.
