The invention discloses a plating pen for the electrical brush plating of an inner hole type spare part, which comprises a pen holder and a pen body, wherein the pen holder comprises a pen holder main body with a hanging part at the upper part and a clamping part at the lower part, and the pen body comprises at least two plate bodies and brush bristles, and the brush bristles are respectively arranged on one side of either plate body which is connected with the pen holder main body; an anode is clamped by the clamping part, the two plate bodies are parallel to both sides of the anode, and thebottom ends of the two plate bodies and the anode are all arranged on an insulated beam and do not mutually contact. The plating pen has simple structure and low manufacture cost, prolongs the service life of the plating pen, saves the consumption of plating liquid, greatly improves the brush plating work efficiency and has favorable market prospects and application prospects.

The invention relates to an all-day automatic tracking system. The system comprises a photovoltaic assembly, an installation platform, hydraulic cylinders, hydraulic cylinder installation seats and a hydraulic control power unit which adjusts the strokes of the hydraulic cylinders; the hydraulic cylinder installation seats are all arranged on the installation platform; the hydraulic cylinders arearranged on the installation platform; each hydraulic cylinder comprises a cylinder body and a piston rod; the cylinder bodies are connected with the hydraulic cylinder installation seats through trunnions; the end of the piston rod of each hydraulic cylinder is connected with the fixed end of the lower surface of the photovoltaic assembly through a universal joint; the all-day automatic trackingsystem also comprises an electric centralized control system for controlling the hydraulic control power unit to act, a follow light sensor used for measuring the required offset adjusting value of the photovoltaic assembly and an inclined sensor used for measuring the position offset adjustment value of the photovoltaic assembly; the horizontal reference surface of the inclined sensor is parallel to the surface of the photovoltaic assembly; and the orientation shaft Z of the follow light sensor is vertical to the surface of the photovoltaic assembly. The all-day tracking system can be used for atrocious weather, can realize accurate automatic tracking and consumes less electricity.

The invention discloses an automobile tow hook device, which comprises a fixed support, a tow hook body, a built-in box, a trailer cable, a limit clip and an opening cover. There is a trailer cable in the box, which effectively protects the trailer cable, prolongs the service life of the trailer cable, and is convenient for carrying the trailer cable. One end of the trailer cable is fixed on the fixed rod, and the other end of the trailer cable passes through The opening extends to one end to open the cover, and one end of the trailer cable is fixedly sleeved on the fixed rod so that one end of the cable is fixed on the fixed rod, and the other end extends from the open cover and is fixed on the hook, and the cable is connected to the trailer when it is extended. It plays the role of double fixation to ensure the fixity and stability of the connection between the trailer cable and the trailer. The trailer cable is fixed at the inner end of the hook-shaped connection section through the limit clip. It is fixed into the support section to further ensure the stability and fixity of the cable.
