When the adjusting swing arm swings left and right, the pair of moving seats are driven to move laterally toward or away from each other, and the pair of moving seats drive the hooks on both sides to move synchronously, so as to adjust the spacing between the hooks on both sides, which is convenient for separating egg trays of different sizes and effectively improves the flexibility of use.

[0045] In this embodiment, Figure 24-26 As shown, a pair of swing connecting rods 203 are respectively hinged with the top surfaces of the front and rear ends of the adjusting swing arm 202, the swing connecting rod 203 located at the front end of the adjusting swing arm 202 extends to the left and is hinged with the bottom of the moving seat 201 located on the left, and the swing connecting rod 203 located at the rear end of the adjusting swing arm 202 extends to the right and is hinged with the bottom of the moving seat 201 located on the right, that is, a pair of swing connecting rods 203 extend to the left and right respectively, and are respectively hinged with a pair of moving seats. During operation, when the adjusting swing arm swings to the left (i.e., swings clockwise), a pair of swing connecting rods pull a pair of moving seats to move toward each other in the lateral direction, thereby reducing the distance between the pair of moving seats; when the adjusting swing arm swings to the right (i.e., rotates counterclockwise), a pair of swing connecting rods push a pair of moving seats to move backwards in the lateral direction, thereby increasing the distance between the pair of moving seats.

[0046] In this embodiment, Figure 24-26 As shown, it also includes a transverse guide member, and a pair of moving seats 201 are distributed at the left and right ends of the transverse guide member and slide with the transverse guide member. The transverse guide member is used to make the moving seat 201 move linearly along the transverse guide member under the drive of the swing connecting rod. Further, the transverse guide member includes a pair of transverse guide rods B204 distributed at intervals in front and rear, and the left ends and right ends of the pair of transverse guide rods B204 are connected by connecting plates B205 respectively, and the front and rear ends of the lower part of the moving seat 201 are both provided with transversely penetrating sliding through holes 206, and the transverse guide rods A204 slide through the sliding through holes 206.

[0047] In this embodiment, Figure 24-26As shown, it also includes a swing locking member for locking the adjusting swing arm 202 after swinging. Specifically, a receiving groove 207 is provided in the middle of the adjusting swing arm 202; the swing locking member includes a locking fixing seat 208 provided in the receiving groove 207, the locking fixing seat 208 is fixed to the dispatching machine and remains stationary, and the adjusting swing arm 202 and the locking fixing seat 208 are rotated and matched, that is, the adjusting swing arm rotates around the locking fixing seat.

When the front end of the clamping push rod is pressed against between two adjacent locking teeth, the adjusting swing arm cannot be swung left and right due to the limitation of the clamping push rod.

[0048] In this embodiment, Figure 24-26 As shown, the rear end of the adjusting swing arm 202 is provided with a longitudinal through hole connected to the accommodating groove 207, and the clamping push rod 210 slides through the longitudinal through hole. The top surface of the rear end of the adjusting swing arm 202 is provided with a long hole 211 extending in the longitudinal direction.

A compression spring 212 is provided in the long hole 211, which is sleeved on the outside of the clamping push rod 210 and extends and retracts in the longitudinal direction. The rear end of the compression spring 212 abuts against the rear end of the long hole 211, and the front end of the compression spring 212 abuts against the annular flange 213 on the outer peripheral side of the clamping push rod 210. Under normal circumstances, the compression spring is in a compressed state. The compression spring 212 uses its elastic force to push the clamping push rod 210 to have a tendency to move forward, so that the front end of the clamping push rod 210 abuts between two adjacent locking teeth 209 to achieve a locked state. When the locking state is to be released, the clamping push rod is manually pulled to the right to separate the front end of the clamping push rod from the locking teeth. At this time, the adjusting swing arm can be swung left and right. After the adjusting swing arm finishes swinging, the clamping push rod is released. The clamping push rod is driven by the elastic force of the compression spring to move forward and be re-locked between two adjacent locking teeth to re-lock the vehicle.

[0049] In this embodiment, in order to facilitate manual pulling of the clamping push rod and left-right swing adjustment of the swing arm, a ball head handle 214 is fixed to the rear end of the clamping push rod 210 .
