The hollow shaft motor has a wide range of uses, such as water pumps, ventilation equipment, booster equipment, small hydroelectric generators, propellers, etc. There is an existing patent for a hollow motor without a central shaft, and the patent publication number is CN217692956U. The utility model relates to the field of hollow motors without a central shaft, and in particular to a hollow motor without a central shaft, including a motor body, a transmission part is provided on the inner side of the middle part of the motor body, and the transmission part is rotatably connected to the motor body, and the inner side of the transmission part is slidably connected to a protective inner cylinder, and the outer side of the protective inner cylinder is fixed. It is connected with a biting ring, which fits with the transmission part, the rear end of the positioning ring is fixedly connected with an elastic plate, and the end of the elastic plate is fixedly connected with a wear-resistant small circular plate. In the utility model, through the provision of a protective inner cylinder, a biting ring, a wear-resistant small circular plate and an elastic sheet, before using the motor body, the staff inserts the protective inner cylinder into the middle through hole of the transmission part of the motor body, positions the protective inner cylinder via the wear-resistant small circular plate, and passes the cable and other linear structures through the protective inner cylinder. During use, the protective inner cylinder will perform bidirectional protection on the cable and other linear structures and the transmission part, reduce friction strength, and reduce damage to the internal structure.

[0003] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: although wear can be reduced during use, since the output shaft of the hollow motor is a hollow metal tube, a corresponding clamping structure is often required to assemble the hollow motor during docking.

Therefore, we proposed a clamping device for the production and development of hollow motors without a central axis to solve the above-mentioned problems. Utility Model Content
