[0026] The outer wall of the transmission gear 18 is meshed with a gear block assembly 20 , the inner wall of the frame body 1 is slidably connected with a counterweight rod 19 , and the gear block assembly 20 is installed on the counterweight rod 19 .

[0027] In this embodiment, the telescopic rod 28 is then extended, and the total extension length of the telescopic rod 28 is divided into three stages. In the first stage, the telescopic rod 28 is extended through the outer base 30 and the inner slide rod 29 to drive the supporting plate 32 and the main limit frame 31 to move upward, so that the first rack 40 drives the second gear 39 to rotate half a circle, and the second gear 39 drives the third bevel gear 34 and the fourth bevel gear 35 to rotate half a circle through the ratchet assembly 38, thereby driving the first shaft rod 5 and the pusher cam 22 to rotate half a circle through the transmission wheel 1 25 and the transmission belt 26, so that the bottom side plate in the side plate limit frame 3 is pushed out by the pusher cam 22 and squeezed into the two clamping plates 15. The two clamping plates 15 clamp the side plates through the first spring 14, and the ratchet assembly 38 is set to be driven to rotate by the second gear 39 only when the telescopic rod 28 is extended.

[0028] In the second stage of the extension of the telescopic rod 28, the main limit frame 31 contacts the bottom end of the counterweight rod 19 to drive the counterweight rod 19 to move upward, and the counterweight rod 19 drives the transmission gear 18 to rotate ninety degrees through the gear block group 20. Through the action of the first bevel gears 7 and the second bevel gears 8, the transmission rod 2 13, the transmission rod 1 9 and the transmission rod 4 21 rotate together, and the limit plate 2 12 contacts the limit plate 1 11 to further limit the side plate. At this time, the four side plates have formed a rectangle.

[0029] Among them, a sixth spring 49 is fixedly connected between the inclined slider 50 and the inner slide rod 29, a third spring 33 is fixedly connected between the insert block 6 and the outer base 30, a inclined limit rod 41 is provided on one side of the insert block 6, and the inclined limit rod 41 is fixedly connected to the main base 2. Four sub-control mechanisms 303 are provided, and the four sub-control mechanisms 303 are distributed in a circular array.

[0030] The inner wall of the mounting plate 2 43 is fixed with a clamping rubber 44, the outer wall of the mounting plate 2 43 is fixed with a connecting rod 45, the connecting rod 45 is slidably connected to the supporting plate 32, the disengagement mechanism 404 also includes a fixing block 1 46 and a fifth spring 47, the clamping rubber 44 is fixed to the mounting plate 2 43, the connecting rod 45 is slidably connected to the supporting plate 32, the fixing block 1 46 is fixed to the supporting plate 32, and the fifth spring 47 is fixed between the supporting plate 32 and the fixing block 1 46. Four disengagement mechanisms 404 are provided, and the four disengagement mechanisms 404 are distributed in a circular array.

[0031] When the fourth spring 42 between the inner slide bar 29 and the outer base 30 is compressed, the bottom plate is pressed against the edges of the four side plates. At the same time, the triangular block 48 gradually approaches the connecting rod 45, causing the connecting rod 45 to move close to the inner slide bar 29. The transmission wheel 1 25 drives the mounting plate 2 43 and the clamping rubber 44 to clamp the junction of the side plate and the bottom plate. The inclined slider 50 moves downward along the inner wall of the outer base 30, and the inclined slider 50 slides to the position of the insertion block 6, pushing the insertion block 6 out. The elastic force of the sixth spring 49 is set to be stronger than the third spring 33. At this time, the inner slide bar 29 is locked by the inclined slider 50. At this time, the operator can apply glue from the inside of the acrylic box through the operation port 4. After the application is completed, the inclined slider 50 has slid to the position of the insertion block 6 and is stuck in the sliding groove inside the outer base 30.

[0032] At this time, the telescopic rod 28 contracts and the connecting rod 45 still clamps the acrylic box with the mounting plate 2 43 and the clamping rubber 44, so that the acrylic box is released from the clamping of the mounting seat 16 and the clamping plate 15 as the telescopic rod 28 contracts, promoting material unloading. Then the counterweight rod 19 moves downward to drive the side plate clamping mechanism 101 to reset. When the insert block 6 gradually contacts the inclined limit rod 41, the insert block 6 squeezes the inclined slider 50, and the inclined slider 50 retracts into the inner slide rod 29 and is gradually reset by the elastic force of the fourth spring 42.

[0033] The following is a detailed explanation of the specific working principle and method of use of the present invention: When in use, the four side panels are placed on the side panel limit frame 3. Several side panels can be stored in the side panel limit frame 3. The size of the side panel limit frame 3 is the same as the side panel. Since the bottom of the side panel limit frame 3 is provided with a limiting inclined plate 23 and a second spring 24, the side panel will not fall off by itself. The bottom panel is placed on the bearing plate 32. The bearing plate 32 is used to support the bottom panel. After the bottom panel is placed, it is at the same height as the L-shaped bracket 27. In the initial state, the inclined slider 50 is as shown in FIG. Figure 10 In the position shown, the inner slide bar 29 is not retracted into the outer base 30 .

[0034] Then the telescopic rod 28 is extended, and the total extension length of the telescopic rod 28 is divided into three stages. In the first stage, the telescopic rod 28 is extended to drive the supporting plate 32 and the main limit frame 31 to move upward through the outer base 30 and the inner slide rod 29, so that the first rack 40 drives the second gear 39 to rotate half a circle, and the second gear 39 drives the third bevel gear 34 and the fourth bevel gear 35 to rotate half a circle through the ratchet assembly 38, thereby driving the first shaft rod 5 and the pusher cam 22 to rotate half a circle through the transmission wheel 1 25 and the transmission belt 26, so that the lowermost side plate in the side plate limit frame 3 is pushed out by the pusher cam 22 and squeezed into the two clamping plates 15. The two clamping plates 15 clamp the side plates through the first spring 14, and the ratchet assembly 38 is set to be driven to rotate by the second gear 39 only when the telescopic rod 28 is extended.

[0035] In the second stage of the extension of the telescopic rod 28, the main limit frame 31 contacts the bottom end of the counterweight rod 19 to drive the counterweight rod 19 to move upward, and the counterweight rod 19 drives the transmission gear 18 to rotate ninety degrees through the gear block group 20. Through the action of several first bevel gears 7 and second bevel gears 8, the transmission rod 2 13, the transmission rod 1 9 and the transmission rod 4 21 rotate together, and the limit plate 2 12 contacts the limit plate 1 11 to further limit the side plate. At this time, the four side plates have formed a rectangle.

[0036] When the telescopic rod 28 is extended, the bottom plate will approach and contact the edges of the four side plates. The fourth spring 42 between the inner slide bar 29 and the outer base 30 is compressed, and the bottom plate is pressed against the edges of the four side plates. At the same time, the triangular block 48 gradually approaches the connecting rod 45, causing the connecting rod 45 to move close to the inner slide bar 29. The transmission wheel 1 25 drives the mounting plate 2 43 and the clamping rubber 44 to clamp the junction of the side plate and the bottom plate. The inclined slider 50 moves downward along the inner wall of the outer base 30, and the inclined slider 50 slides to the position of the insertion block 6, pushing the insertion block 6 out. The elastic force of the sixth spring 49 is set to be stronger than the third spring 33. At this time, the inner slide bar 29 is locked by the inclined slider 50. At this time, the operator can apply glue from the inside of the acrylic box through the operation port 4. After the application is completed, the inclined slider 50 has slid to the position of the insertion block 6 and is stuck in the sliding groove inside the outer base 30.

[0037] At this time, the telescopic rod 28 contracts and the connecting rod 45 still clamps the acrylic box with the mounting plate 2 43 and the clamping rubber 44, so that the acrylic box is released from the clamping of the mounting seat 16 and the clamping plate 15 as the telescopic rod 28 contracts, promoting material unloading. Then the counterweight rod 19 moves downward to drive the side plate clamping mechanism 101 to reset. When the insert block 6 gradually contacts the inclined limit rod 41, the insert block 6 squeezes the inclined slider 50, and the inclined slider 50 retracts into the inner slide rod 29 and is gradually reset by the elastic force of the fourth spring 42.

[0038] It is further explained that the above-mentioned fixing should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are common means well known to those skilled in the art.

[0039] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
