Further, the clamping piece comprises the fixed column of through bolt fixed mounting on the stores pylon, establish at the anterior screw hole of fixed column, establish at the fixed column lateral wall and correspond the side opening of screw hole rear end and install the screw in the screw hole, puts into side opening and fastening screw with the electron tube cathode both ends, and the screw is with the centre gripping of electron tube cathode both ends on the fixed column.
Furthermore, a guide hole extending along the vertical direction is formed in the upper portion of the hanging rack, a pull plate capable of sliding up and down is installed in the guide hole, the sliding plate is fixedly installed at the lower end of the sliding plate, and the sliding plate can move up and down through the pull plate.
Furthermore, a vertical screw rod is arranged at the upper end of the hanger, the screw rod vertically penetrates through the upper end of the pull plate, a nut is arranged at the upper end of the screw rod, a spring is arranged between the hanger and the upper end of the pull plate on the screw rod, a lower screw nut overcomes the elastic force of the spring to push the pull plate to move downwards, and an upper screw nut pushes the pull plate to move upwards under the elastic force of the spring.
The beneficial effects of the utility model are:
because two clamping pieces which are arranged left and right are arranged at the lower part of the hanging rack, a plurality of lower hanging pins which are arranged left and right are arranged on the hanging rack above the clamping pieces, a sliding plate which slides up and down is arranged at the upper part of the hanging rack, upper hanging pins which are arranged left and right are arranged on the sliding plate, and the lower hanging pins and the upper hanging pins are arranged in a staggered way up and down. During the shaping operation, at first with the centre gripping of negative pole left end fix on left clamping piece, then walk around lower peg and last peg with the negative pole in proper order to fix the clamping piece of negative pole right-hand member centre gripping on the right side, then shift up the slide and make the negative pole tighten and shaping, the negative pole shaping shape is standard, has improved the cathode performance, has improved the service quality of electron tube.
