[0024] As Figure 1 , 2 shown in the figure, a screwing type radial locker for clamping a capacitor shell is composed of a plurality of arc-shaped bodies 101 connected at the bottom and parted at the top, the outer periphery of the lower section has external threads, the outer periphery of the middle section is a conical body 103 with the upper part larger than the lower part, and the outer periphery of the upper section is a cylindrical surface, the inner end of which has an accommodating cavity 102 for accommodating the capacitor shell 4 formed by the plurality of arc-shaped bodies 101, the plurality of arc-shaped bodies 101 can clamp the capacitor shell 4 by converging towards the center, and the slot 1011 for inserting a shifting member is formed at the upper end of the arc-shaped body 101 and opens on the upper end surface and the outer periphery, and the inserted shifting member can slide radially in the slot 1011. In application, the capacitor shell is placed in the accommodating cavity 102 of the radial locker 1, and then the lower part of the radial locker 1 is inserted into the sleeve cavity 301, the shifting member is inserted into the slot 1011, and the shifting member is subjected to a force along the circumferential direction of the radial locker 1 to make the radial locker 1 rotate, the external threads of the lower section of the radial locker 1 are screwed into the internal threads of the threaded hole at the bottom of the sleeve cavity 301 of the rotating seat, the radial locker 1 is pushed into the sleeve cavity, and the outer taper of the radial locker 1 is constantly subjected to the radial centripetal extrusion of the inner taper of the sleeve cavity, so that the plurality of parted arc-shaped bodies constantly converge towards the center to clamp the capacitor shell 4 radially. In this way, the slot 1011 easily creates conditions for the radial locker 1 to be screwed into the sleeve cavity 301 of the rotating seat 3 and for the capacitor shell 4 to be clamped. Embodiment II

[0025] As Figure 3 -5 shown and in reference to Figure 2 , 7A screwdriver for tightening the aforementioned radial locking device includes a torque disc 201 and a lever 202, which are suspended on the outer periphery of the lower surface of the torque disc 201. The position and number of the lever 202 correspond to the slot 1011 at the upper end of the radial locking device 1. In application, rotating the torque disc 201 causes all the lever 202 to simultaneously apply force to the radial locking device 1, thus easily screwing the radial locking device 1 into the tightening cavity 301 of the rotating seat 3 and locking the capacitor housing 4.

[0026] The aforementioned screwdriver 2 also includes a rotating handle 203. A column 204 is provided at the center of the torque disc 201, and the rotating handle 203 is located at the upper end of the column 204.
