The invention relates to the technical field of massager, in particular to a head massager. The head massager comprises a base, a footstock which is in a coordination and connection with the base, a slider and a arc-shaped shell body. Two sides of the footstock are provided symmetrically with a fixed hole and a perforation. A fixed block A and an eccentric fixed block B are installed inside two perforations which are installed symmetrically. An eccentric shaft A is installed fixedly on the eccentric fixed block A and the eccentric block B is provided fixedly with an eccentric shaft B. One end of the slider is provided longitudinally with a kidney-shaped hole. The other end of the slider is provided longitudinally with a location hole A. A location hole B is installed on the middle portion of the slider. The eccentric shaft A and the eccentric shaft B is fixedly connected with location holes A which are installed on the two sliders. The slider is connected with the outside of the arc-shaped shell through a bolt which is penetrates through the location hole B. An actuating device drives the eccentric fixed block A and the eccentric fixed block B to rotate. The head massager has the advantages of being tight in structure, reasonable in design, suitable for different consumers and uniform in massage strength and swing.

The invention discloses rod rubbing heads, a rod rubbing device for a coal mine underground power head drilling machine and a tripping method. The rod rubbing device comprises the two rod rubbing heads, a clamping unit mounted on the lower parts of the two rod rubbing heads, a sliding frame and an integrated valve set; rubbing wheels of the two rod rubbing heads are oppositely arranged and are parallel mutually; the clamping unit comprises a central plate, and the central plate is connected with a left side plate and a right side plate which are located on the two sides of the central plate; the two rod rubbing heads are mounted at the upper ends of the left side plate and the right side plate correspondingly; the sliding frame comprises a mounting base, a positioning plate and sliding rails vertically mounted between the mounting base and the positioning plate, wherein the mounting base and the positioning plate are parallel mutually; the sliding rails penetrate through the central plate and are parallel to the rubbing wheels of the rod rubbing heads; and the integrated valve set is connected with the rod rubbing heads and the clamping units through wires correspondingly. The rotating speed of a drill rod driven by the rod rubbing device is 2-4 times the rotating speed of the drill rod driven by a power head; and by arranging the integrated valve set, the rotating speed and the axial moving speed of the drill rod are matched, and thus the rod rubbing device is adaptable to different specifications of drill rods.

The invention discloses a spliced type intelligent child carrier and a splicing method thereof. The spliced type intelligent child carrier comprises a box body. A fixing mechanism is suspended in the box body through a suspension support. A splicing mechanism used for taking of children is arranged in the fixing mechanism. A splicing locating case is arranged in the splicing mechanism and provided with a first seat, a second seat and a splicing flat board. The first seat and the second seat are provided with a temperature sensor and a humidity sensor. A control box is further arranged in the box body. The first seat and the second seat are distributed symmetric about the center of the splicing flat board so that the space of the splicing flat board can be more effectively used by the two children. By the adoption of the spliced type intelligent child carrier, the splicing mechanism is arranged to achieve multiple functions, so that the purpose that the children can take the carrier and have a rest conveniently is achieved; a spring damping system imitating that of an automobile is adopted so that the children can better fall asleep; and a full-suspension system is adopted in the splicing mechanism so that the jolting feeling caused by the splicing mechanism can be relieved when the ground is rugged.

The invention discloses a sintered brick setting machine. The sintered brick setting machine is characterized in that a balance frame is composed of a vertical frame and a multi-connecting-rod telescopic frame, a lifting component is formed by a servo motor, a driving chain wheel, a first fixed pulley, a second fixed pulley, a chain and a driven chain wheel, the chain is sequentially connected with the driving chain wheel, the driven chain wheel, the first fixed pulley and the second fixed pulley, and a balance weight is connected with the tail end of the chain; and a green brick clamping device comprises a clamping disc, a telescopic frame and a clamp, the clamp disc is connected with a rotating device, air cylinders are fixed to the telescopic frame, clamping plates penetrate telescopic rods, every two adjacent clamping plates are connected to form linkage through a corresponding connecting rod, the clamping disc is provided with air storage tanks, and the air cylinders communicate with the air storage tanks through air distributing pipes, and the air inlet ends of the air distributing pipes are connected with air pressure adjusters. According to the sintered brick setting machine, the clamping force of the clamping plates can be finely adjusted, green bricks are prevented from being extruded and damaged, a lifting device can prevent the green brick clamping device from swinging in the ascending process, the green bricks can stably move and the setting quality and efficiency are improved.

The invention discloses a shaft end face printing mechanism. According to the mechanism, the problem that the shaft end face cannot be accurately printed is solved; the shaft end surface printing mechanism comprises a printing device and a supporting device, wherein the printing device can be detachably connected to the supporting device, and the supporting device can be supported on a shaft part,a printing head of the printing device penetrates through the supporting device to carry out printing operation on the end face of the shaft part, and the problem that the end face of the shaft partis inconvenient to print and load is solved; the operation cost is greatly reduced, the distance between the printing head and the shaft end face can be effectively adjusted, and the printing efficiency and precision are improved; and the cooperation of the whole device is compact in structure, simple in part, low in cost and high in efficiency, and the problem that the end face of the shaft partcannot be printed efficiently and accurately is well solved.
