The horizontal plate 203 is provided with a double-shaft driving motor 204, and the two output ends of the motor are connected to an adjusting screw rod one 205 and an adjusting screw rod two 206, respectively. The two adjusting screw rods are rotatably arranged on the inner walls of the vertical plate one 201 and the vertical plate two 202, respectively, and the screw threads of the two adjusting screw rods are opposite in direction.

[0027] On the adjusting screw rod one 205 and the adjusting screw rod two 206, a screw nut pair one 207 is threadedly connected.
