One end of the first push rod 62 is fixed on the rotating shaft of the first motor 61. The first slider 63 is screwed to the first push rod 62. The first sliding block 63 is fixed to the first straight section 21, so that the first sliding block 63 drives the portion, connected to the first straight section 21 and the first sliding block 63, to move by half the target distance along the first target direction under the rotation of the first motor 61.
Further, referring to fig. 10 and 11, the second driving assembly 7 includes a second motor 71, a second push rod 72 and a second sliding block 73. One end of the second push rod 72 is fixed to the rotating shaft of the second motor 71. The second slider 73 is screwed to the second push rod 72. The second slider 73 is fixed to the second straight section 23, so that the second slider 73 drives the portion of the second straight section 23 connected to the second slider 73 to move by half the target distance along the second target direction under the rotation of the second motor 71.
The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations are also considered as the protection scope of the present invention.
