It should be noted that, when the front plate 101 is not buckled with the left plate 104 and the right plate 105, the spring 104c-1 is in a normal state, and at this time, the distance from the top end of the movable buckle 104c-2 (the top end refers to the end of the movable buckle 104c-2 contacting with the round bump 101a) to the first fixed rod 104d is smaller than the distance between the first fixed rod 104d and the second fixed rod 104 b. When the front plate 101 is buckled with the left plate 104 and the right plate 105, the spring 104c-1 is in a compressed state, and the movable buckle 104c-2 moves from one end of the circular convex block 101a to the other end of the circular convex block 101 a. Since the cross section of the movable buckle 104c-2 is composed of a rectangular shape and a triangular shape, the rectangular portion is for better contact with the second fixing rod 104b and does not wear the components, and the triangular portion is for easy disassembly after assembly, and since the buckle portion is an inclined surface, when disassembling, only a force is applied to the front plate 101 to make it move in the opposite direction relative to the original buckle direction, so that the front plate 101 can be disassembled.

Referring to fig. 1-10, a second embodiment of the easily detachable document positioning device of the present invention, which is different from the first embodiment, is: the bottom panel 102 and the rear panel 103 are foldable.

It should be noted that, when the front plate 101 is not buckled with the left plate 104 and the right plate 105, the spring 104c-1 is in a normal state, and at this time, the distance from the top end of the movable buckle 104c-2 (the top end refers to the end of the movable buckle 104c-2 contacting with the round bump 101a) to the first fixed rod 104d is smaller than the distance between the first fixed rod 104d and the second fixed rod 104 b. When the front plate 101 is buckled with the left plate 104 and the right plate 105, the spring 104c-1 is in a compressed state, and the movable buckle 104c-2 moves from one end of the circular convex block 101a to the other end of the circular convex block 101 a. Since the cross section of the movable buckle 104c-2 is composed of a rectangular shape and a triangular shape, the rectangular portion is for better contact with the second fixing rod 104b and does not wear the components, and the triangular portion is for easy disassembly after assembly, and since the buckle portion is an inclined surface, when disassembling, only a force is applied to the front plate 101 to make it move in the opposite direction relative to the original buckle direction, so that the front plate 101 can be disassembled. When the document placing device is not needed to be used, the supporting assembly 200 can be detached from each document basket 100, the front plate 101 is detached from the left plate 104 and the right plate 105, and finally the bottom plate 102 and the rear plate 103 are folded, so that the placing space is reduced and the carrying is convenient when articles are arranged.

Referring to fig. 1-10, a third embodiment of the easily detachable document positioning device of the present invention is different from the second embodiment in that: the support assembly 200 can be extended and shortened according to the needs of a user.

document baskets

Wherein the bottom panel 102 and said back panel 103 are foldable.

The support assembly 200 includes a first connecting rod 201 and a second connecting rod 202, one end of the first connecting rod 201 is provided with a tabling hole 201a, an elastic member 201b is arranged in the tabling hole 201a, the second connecting rod 202 includes an extension rod 202a and a rod body 202b, the extension rod 202a is connected with the rod body 202b, and the extension rod 202a is provided with a matching block 202 a-1.

The fitting hole 201a is not a through hole, and is recessed inward from the end surface of the first connecting rod 201, and the recessed distance is not greater than two thirds of the length of the first connecting rod 201.

It should be noted that, the fitting hole 201a is further provided with a first groove 201a-1 and a second groove 201a-2, so that the cross section of the fitting hole 201a is not completely circular, and the cross section at the first groove 201a-1 and the second groove 201a-2 is approximately "U", that is, the cross section of the first groove 201a-1 and the second groove 201a-2 is "L".

The second connecting rod 202 comprises an extension rod 202a and a rod body 202b, and the extension rod 202a is connected with the rod body 202b, wherein a matching block 202a-1 is arranged on the extension rod 202a, and the matching block 202a-1 can be respectively matched with the first groove 201a-1 and the second groove 201a-2, but is not matched with the first groove 201a-1 and the second groove 201a-2 at the same time.

Preferably, in order to enable the engaging block 202a-1 to engage with the first groove 201a-1 and the second groove 201a-2 respectively without interfering with the movement between the first connecting rod 201 and the second connecting rod 202, in the present invention, a first sliding plate 201c is disposed in the first groove 201a-1, and a rack is disposed on the first sliding plate 201c, and the engaging block 202a-1 is a gear, and the gear and the rack are engaged with each other.

Similarly, a second sliding plate 201d is arranged in the second groove 201a-2, a rack is arranged on the second sliding plate 201d, the mating block 202a-1 is a gear, and the gear and the rack are engaged with each other.

Preferably, the initial position of the first sliding plate 201c is at the lowest end of the first groove 201a-1, so as to ensure that the rack on the first sliding plate 201c can be engaged with the gear on the engaging block 202a-1, and at this time, it is just enough to enable the engaging block 202a-1 and the rack to move left and right in the direction of the generatrix of the first connecting rod 201.

Since the rack of the first sliding plate 201c is in the extended state of the rod when it can be engaged with the gear of the engaging block 202a-1, that is, when the elastic member 201b is not normally pressed, in order to prevent the engaging block 202a-1 and the rack from being limited in the left-right direction (the direction of the generatrix of the first connecting rod 201) without the external force, in the present invention, the original length of the elastic member 201b and the distance from the end surface of the extending rod 202a to the engaging block 202a-1 are equal to the distance from the engaging block 202a-1 to the bottom end of the engaging hole 201a, and are also equal to the distance from the first groove 201a-1 to the bottom end of the engaging hole 201 a.
