The invention discloses a table tennis racket with the function of exercising the hands. The table tennis racket includes a racket plate, the lower side of the racket plate is fixedly connected with agrab handle, the two sides of the grab handle are provided with installation plates, the side, near the grab handle, of each installation plate is fixedly connected with two symmetrically arranged connection plates, the connection plates are connected with the grab handle through clamp connection mechanism, the sides, away from the connection plates, of the installation plates are connected withplatform plates through several first telescopic rods, the sides, away from the connection plates, of the installation plates are fixedly connected with installation covers, and the installation covers are rotatably connected with first bevel gears through first transmission shafts. By arranging the clamp connection structure, after playing table tennis, the installation plates can be convenientlyconnected with the grab handle through clamping, at this moment, the distance between grip frames on the two sides can be adjusted through a lifting mechanism according to the size of the user's palms, users thus conveniently put the hands in the grip frames, and massage and relaxation of muscles of the hands of the users is thus facilitated.

The present invention relates to a telescopic temperature-measuring head for measuring transmission medium temperature of buried pipeline. It is characterized by that after the tail portion of temperature-measuring head inserted into the pipeline from the temperature-measuring head mounting shell body fixedly connected with exterior of pipeline is passed through isolation valve, it is series-connected with spacing mechanism and movement mechanism, it can make pipe scraper or detector smoothly pass through and can ensure safety of the temperature-measuring head.

The invention discloses a granary for grain storage which is convenient for moving and transporting. A high-pressure centrifugal fan is fixedly connected to the lower surface of the horizontal plate, and the suction end of the high-pressure centrifugal fan communicates with one end of the hose. The granary for grain storage, which is convenient for moving and transferring, is provided with electric push rods. When the two electric push rods are extended or shortened, the two electric push rods drive the two connecting plates to rotate around the auxiliary device through the two movable devices, so that the belt It can be easily erected to the through hole of the granary, and then the grain in the granary is extracted through the high-pressure centrifugal fan, hose and suction nozzle and transported to the belt through the iron pipe, grain storage bucket and cloth bag, and the belt rotates to transport the grain to the car, In this way, it becomes very convenient to transport food, and at the same time reduces the labor intensity of people.

The invention relates to a clamping device for porcelain glazing, which includes a clamping rod, a support tube, a clamping claw and a controller. There is a handle on the clamping rod, and a brake handle is hinged under the handle. The support tube is The tube body, the annular array at the top of the support tube has a plurality of outwardly inclined support claws, the clamping claw is a rod body, the controller includes a control claw and a brake line, the control claw includes a collar and a control rod, and the clamping claw is in the When the brake handle is not under force, it moves closer to the second vertical pipe, and the free end of the clamping claw shrinks toward the center of the second vertical pipe, so that it can be easily inserted into the blank with a narrow opening. When the supporting claw touches the bottom of the blank bottle, tighten it manually Brake handle, the brake handle pulls the brake line, so that the connecting rod drives the collar to slide down. When the collar slides down, the control rod pulls the clamping claws to prop up around, and is stuck on the shoulder of the bottle. Together with the supporting claws, the narrow The blank of the mouth is clamped stably, and the inner and outer walls are glazed at one time, which saves time and effort.

The invention provides a turning lifter for assembling an impeller of a wind generating set; the turning lifter comprises two scissor-shaped lifters; each scissor-shaped lifter comprises two rod pieces; the two rod pieces are crossed with each other, and are hinged through a hinged shaft; the rod pieces on one sides of the hinged shafts form scissor openings; the rod pieces on the other sides of the hinged shafts form scissor handles; holding structures are arranged at the ends of two supporting rods on one sides of the scissor openings, and are matched with the shapes and / or structures of corresponding places of wheel hubs of the impeller; telescopic devices are arranged between the two rod pieces on one sides of the scissor handles; fixed pieces of the telescopic devices are arranged on one of the rod pieces; the outer ends of telescopic pieces of the telescopic devices are fixed on the other one of the rod pieces; the telescopic devices are driven manually; unloading buckles are arranged on the rod pieces for connecting with slings which are connected with a crane. The turning lifter can implement the rabbit ear type impeller splicing; as the turning lifter is controlled by a manual mechanical system, the operation is simple, and the economy is good; the lifter is convenient for maintenance and use, and is flexible and convenient for disassembly.
