[0054] The working principle of the embodiment one is as follows:

[0055] The first step is to adjust the tray, according to the width of the truck compartment, the head 2.11 of the adjusting mechanism 2 can be rotated by the inner hexagonal wrench, so that the worm 2.1 rotates, and the worm 2.1 rotates at the same time to drive the worm gear 2.3 in the middle of the two bidirectional screw rods 2.2 to rotate, so that the two bidirectional screw rods 2.2 can drive the two auxiliary brackets 3 to expand and contract on both sides of the upper surface of the main bracket 1 simultaneously, thereby adjusting the width of the tray to adapt to the width of the truck compartment, reducing the gap between the tray and the truck compartment, avoiding the tray from shaking during transportation, and reducing the degree of collision of tobacco goods;

[0056] The second step is to load the goods: first, load the goods on the tray, then lift the push wrench 5.12 upward with your hand, so that the outer ratchet 5.10, the pawl 5.8, the spring piece 5.7 and the fixed wheel 5.4 rotate clockwise at the same time, during the rotation process, the lever 5.9 will not move because it is fixed in the rectangular groove 8, but the spring piece 5.7 will be pressed downward by the lever 5.9 during the clockwise movement, so that the spring piece 5.7 slides along the arc-shaped sliding groove 5.81, and the pawl 5.8 rotates downward and is separated from the tooth groove of the inner ratchet 5.2 by the downward swing of the spring piece 5.7, which releases the one-way intermittent movement of the inner ratchet 5.2, so that the inner ratchet 5.2 can rotate, and the clamping piece 5.11 is clamped in the tooth groove of the outer ratchet 5.10, preventing the outer ratchet 5.10, the pawl 5.8, the spring piece 5.7 and the fixed wheel 5.4 from automatically resetting due to the gravity of the push wrench 5.12 itself;

[0057] Third step binding, the binding belt 4.2 is pulled out from the containing groove 9 by pulling (the hollow shaft 4.1 also rotates clockwise at the same time, and the two coil springs 4.3 on the hollow shaft 4.1 begin to be elastically compressed), the binding belt 4.2 is finally buckled on the hook 6 by being wrapped around the top of the goods, and the preliminary binding is completed; after buckling, the rebounding reaction force of the two coil springs 4.3 acts on the hollow shaft 4.1, forcing the hollow shaft 4.1 to rotate counterclockwise to pull the binding belt 4.2 back and pre-clamp the surface of the goods; then the clamping piece 5.11 is taken out, so that the outer ratchet 5.10, the pawl 5.8, the spring piece 5.7 and the fixed wheel 5.4 can rotate, and the pushing wrench 5.12 is pressed downward by hand, so that the outer ratchet 5.10, the pawl 5.8, the spring piece 5.7 and the fixed wheel 5.4 rotate counterclockwise at the same time, the spring piece 5.7 begins to swing upward and reset, the pawl 5.8 rotates upward and is clamped in the tooth groove of the inner ratchet 5.2, the one-way intermittent motion mode of the inner ratchet 5.2 is started, the pushing wrench 5.12 is continuously pressed downward, the inner ratchet 5.2 can rotate counterclockwise by the pawl 5.8, the binding belt 4.2 is further clamped, and the clamping piece 5.11 is reinserted into the limiting sliding groove 12, the clamping piece 5.11 is reconnected with the outer ratchet 5.10, the clamping process of the binding belt 4.2 is realized, compared with the traditional fixed mode, it is more time-saving and labor-saving, the operation steps are simple, and the fixing is firm.

[0058] Example two

[0059] Please refer to Figure 16 and Figure 17 , compared with example one, the overall structure of example two is basically the same, the difference between the two is that the locking mechanism 5 is different, the locking mechanism 5 of example two comprises: an L-shaped tooth pressing plate 5.13 opposite to the belt outlet 11, the middle part of the L-shaped tooth pressing plate 5.13 is rotationally connected with the first square steel 1.2 or the third square steel 3.2 at the belt outlet 11, and teeth for pressing the binding belt 4.2 are arranged at the end of the L-shaped tooth pressing plate 5.13 adjacent to the belt outlet 11.

[0060] The working principle of the second embodiment is only the first step same as the working principle of the first embodiment, because the locking structure 5 is not the same, so the binding way is relatively simple, need first through the pull out of the binding belt 4.2 from the containing slot 9 (hollow shaft 4.1 also happens at the same time clockwise rotation with the pull out of the binding belt 4.2, two coil springs 4.3 on the hollow shaft 4.1 begin elastic compression), through the binding belt 4.2 around the top of the goods, finally the binding belt 4.2 on the card slot 4.21 buckle on the hook 6 complete preliminary binding;After buckling, the elastic force of two coil springs 4.3 acts on the hollow shaft 4.1, forcing the hollow shaft 4.1 counterclockwise rotation pull the binding belt 4.2 retract to the surface of the goods for pre-clamping;Finally push up the tooth pressure plate 5.13, use the tooth pressure plate 5.13 bottom one end of a plurality of teeth into the surface of the binding belt 4.2, when the tooth pressure plate 5.13 top one end buckle in the surface of the binding belt 4.2, complete clamping fixed operation steps simple, simple structure, but compared with the clamping effect of the first embodiment is low.

[0061] The above only for the preferred embodiment of the present application, and not to limit the present application, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application, should be included in the protection scope of the present application.
