Referring to fig. 2 to 6, the first locking mechanism includes a locking hole 30, a locking rod 31 and a driving lever 32, the locking hole 30 is disposed on a third side of the lower folding seat 20, the locking rod 31 is elastically disposed on a third side of the upper folding seat 10 and can be in plug-in fit with the locking hole 30, one end of the driving lever 32 is connected with the locking rod 31 in a positioning manner, the other end of the driving lever 32 extends to the first side of the upper folding seat 10, and the driving lever 32 drives the locking rod 31 to reciprocate along the axis direction thereof.

Further, the first locking mechanism further includes two connecting pieces 33 and a return spring 34, the connecting pieces 33 are provided with two connecting pieces 33, the two connecting pieces 33 are arranged on the third side of the upper folding seat 10 side by side along the axial direction of the lock rod 31, one ends of the two connecting pieces 33 are provided with through holes 330 for the lock rod 31 to penetrate, the return spring 34 is sleeved on the lock rod 31, and two ends of the return spring 34 are respectively elastically abutted to the deflector rod 32 and one connecting piece 33. The other ends of the two connecting pieces 33 are respectively provided with a lug 331, the two lugs 331 extend out of the second side of the upper folding seat 10, and the two lugs 331 are connected through a first pin shaft 35. The third side of the lower folding seat 20 is provided with a lock seat 201, the lock hole 30 is arranged on the lock seat 201, and the third side of the upper folding seat 10 is provided with a lock seat groove 101 matched with the lock seat 201. The first side of the upper folding seat 10 is provided with an avoidance notch 102, the deflector rod 32 comprises a connecting part 321 and a stirred part 322, the connecting part 321 is in positioning connection with the lock rod 31, the stirred part 322 is stretched into the avoidance notch 102,

specifically, a space for arranging the lock rod 31, the return spring 34 and the deflector rod 32 is formed between the two connecting pieces 33, the lock rod 31 is in a cylindrical structure, two ends of the lock rod 31 respectively pass through holes 330 formed in the two connecting pieces 33, and the return spring 34 is sleeved on the lock rod 31 between the two connecting pieces 33. The connecting portion 321 of the shift lever 32 is fixed on the lock lever 31, that is, the connecting portion 321 of the shift lever 32 is located between the connecting piece 33 of the through hole 330 near the third side and the return spring 34, that is, two ends of the return spring 34 respectively elastically abut against the connecting portion 321 of the shift lever 32 and the connecting piece 33 of the through hole 330 far from the third side. The shifted portion 322 of the shift lever 32 extends beyond the first side of the upper folding seat 10, so as to be convenient for the user to push in a hand. In addition, as can be seen from fig. 4, the first pin 35 is composed of two parts, namely, a fixed shaft and a rotating sleeve sleeved on the fixed shaft, the fixed shaft rotatably mounts the rotating sleeve on the second side of the upper folding seat 10, and when the handle 40 is opened or locked, the end part of the upper connecting rod 62 is pressed against the rotating sleeve, and the rotating sleeve rotates along with the rotating sleeve, so that the pulling force of the handle 40 in the opening or locking process is reduced.

It can be understood that when the user holds the poked portion 322 of the poking rod 32 to push the poking rod 32 on the upper folding seat 10 towards the side far away from the third side, the poking rod 32 will drive the lock rod 31 connected with the poking rod 32 to move synchronously, the reset spring 34 is stressed and compressed, at this time, the end portion of the lock rod 31 originally inserted into the lock hole 30 of the lower folding seat 20 moves synchronously and synchronously until the end portion of the lock rod 31 is completely separated from the lock hole 30, so that the lower folding seat 20 and the upper folding seat 10 are in the unlocking state, and then the upper portion of the upper folding seat 10 is manually pulled, so that the second side of the upper folding seat 10 is far away from the second side of the lower folding seat 20, so that the folder is in the opening state, and at the same time, after the poking rod 32 is released, the lock rod 31 is restored to the initial state under the elastic force of the reset spring 34.

In addition, since the first sides of the lower folding seat 20 and the upper folding seat 10 are connected through the pin shaft, the side of the lower folding seat 20 and the upper folding seat 10, which are originally attached, can be unfolded to be in a horizontal state, that is, the lower folding seat 20 and the upper folding seat 10 are in a folded state. When the user approaches the second sides of the upper folding seat 10 and the lower folding seat 20 relatively, the lock rod 31 moves to the side far away from the third side under the action of the return spring 34, and when the second sides of the upper folding seat 10 and the lower folding seat 20 are in a fitting state, the lock rod 31 springs into the lock hole 30 under the action of the return spring 34, so that automatic locking is achieved. Namely, the first locking mechanism of the folder provided by the utility model has the characteristics of manual unlocking and automatic locking.

Next, a description is given of the second locking mechanism.

It should be noted that, the second locking mechanism is used for further locking the fitting locking state of the first locking mechanism, so that the folder of the present utility model has a double locking function, that is, the first locking mechanism and the second locking mechanism both have locking functions, which can be alternatively or simultaneously arranged on the folder, so as to realize the double locking function of the folder of the present utility model, in this embodiment, the folder is simultaneously provided with the first locking mechanism and the second locking mechanism.

Referring to fig. 2, 7 and 8, the second locking mechanism includes a handle 40, a hook a driving assembly disposed on the handle 40, and a hook B11 disposed on a second side of the upper folding seat 10; the handle 40 is rotatably connected with the second side of the lower folding seat 20 through a second pin 41, and the hook A driving assembly comprises a switch seat 50 slidably arranged on the handle 40 and a hook A51 fixedly connected with the switch seat 50, wherein the hook A51 is in clamping fit with the hook B11.
