A sliding rod 62 is slidably connected in the sliding sleeve 61, and the two ends of the sliding rod 62 are respectively connected to the clamping plate 63 and the stopper 64. By setting the stopper 64, the stopper 64 can limit the sliding rod 62, so that the moving clamping plate 63 will not drive the sliding rod 62 to move out from the side of the device housing 11;
[0022] The outer sleeve of the slide rod 62 is connected with a spring 7. By setting the slide sleeve 61 and the slide rod 62, since the slide rod 62 is slidably connected in the slide sleeve 61, the slide sleeve 61 can limit the slide rod 62, so that the slide rod 62 will not shake when moving, and the clamping plate 63 connected to the slide rod 62 can move smoothly along the axial direction of the slide sleeve 61;
