The adjustable adhesive tape winding device comprises a bottom frame, one end of the bottom frame is rotationally provided with a roller used for supporting an adhesive tape roll, one end of the roller is rotationally connected to a first wall plate, the first wall plate is vertically connected to the bottom frame, the other end of the roller is provided with a pin rod assembly, and the outer side of the roller is provided with a pressing rod. The lower end of the pressing rod is rotationally connected to an end frame, the end frame is connected to the end of a bottom frame, a mandrel is rotationally arranged at the other end of the bottom frame, one end of the mandrel is rotationally connected to the wall plate II, the end of the mandrel is connected with an output shaft of a low-speed motor, and the other end of the mandrel is connected to the bottom frame through an adjustable mechanism; the device is simple in structure, reasonable in design and novel and unique in thought, the roller is sleeved with the adhesive tape roll, the adhesive tape roll is fixed and limited through the pin assembly, it is guaranteed that the roller is stably sleeved with the adhesive tape roll, in addition, the core shaft driven by the low-speed motor is matched to rotate, and the coil sleeved with the core shaft is wrapped and wound with the adhesive tape.

This invention discloses a hemostatic collar installation device, including a mounting base on which a No. 1 support plate and a No. 2 support plate are fixedly mounted. A sleeve is horizontally arranged on the No. 1 support plate, and an installation cone is provided at one end of the sleeve. A bandage installation plate is installed on one side of the No. 2 support plate, and the bandage installation plate is provided with multiple sets of bandage installation slots. A fixing block is detachably mounted on each bandage installation slot. The same set of bandages is fixedly engaged on both the bandage installation slot and the fixing block. The connecting base allows for easy fixing of the entire device on a table; the installation cone allows for easy fitting of the hemostatic collar and tightening collar onto the sleeve; the bandage installation slots and fixing blocks facilitate the fixed installation of the bandage; and the baffle at the end of the bandage prevents the bandage from being pulled out during pulling after it has been fixed.

The application belongs to the technical field of sealing test devices, and specifically provides a gas tightness test clamp. The gas tightness test clamp comprises an inlet joint and an outlet joint. The inlet joint is provided with a mounting hole for mounting the inlet end of a tested thin-walled cylinder, and the outlet joint is provided with a mounting hole for mounting the outlet end of the tested thin-walled cylinder. The mounting holes of the inlet joint and the outlet joint are both provided with a sealing ring for sealing cooperation with the circumference of the tested thin-walled cylinder. The inlet joint is provided with a sealing connection structure for sealing connection with a test bench and a gas passage. The inlet joint and the outlet joint in the application are both in sealing cooperation with the outer circumference of the tested thin-walled cylinder, and the sealing ring does not contact the sharp end of the thin-walled cylinder, so that the bolts and flange plates do not need to be disassembled and assembled multiple times. Compared with the bolt flange type sealing clamp, the reliability of the clamp and the test is greatly improved.

The utility model relates to the technical field of protective shells, and discloses a middle frame and a mobile phone cover, which comprise a frame body, the middle part of the frame body is provided with an opening to form an annular hollow outline structure, the inner wall of the opening is set as a flat area, and the edges of the two opposite ends of the opening extend inwards to respectively form a first covered edge and a second covered edge for supporting and positioning. Through the opening and the flat area arranged on the inner wall of the opening, the mobile phone main body is sleeved. The edges of the two opposite sides of the opening respectively extend inwards to form the first covered edge and the second covered edge, so that the periphery of the mobile phone is limited and supported, the mobile phone is prevented from shaking in the middle frame, the mobile phone is prevented from being damaged due to collision or movement, and reliable protection is provided for the mobile phone. The annular hollow outline structure is formed through the opening, so that the back of the mobile phone is not shielded on the basis of guaranteeing the protection performance, the heat dissipation performance is greatly improved, and the influence of heat accumulation on equipment operation is reduced.
