Preferably, the locking mechanism 2 includes a limit device 4 and an adjustment locking device 5; the limit device 4 includes a trigger 41, a limit hook 42, a slider upper shell 43, a slider lower shell 44, and a slider 45; the slider lower shell 44 is fixed to the lower shell 3 by screws; a square hole 46 is penetrated and set on the upper surface of the slider upper shell 43, and the slider upper shell 43 is set above the slider lower shell 44 by screws to form a hollow slide 47, and a slide 45 is set in the slide 47, and the shape of the slide 45 matches the shape of the slide 47; the trigger 41 includes an arc plate 411, a rotating plate 412, and an arc plate 411 is an upwardly protruding arc, and a rotating plate 412 is vertically arranged at the center below the arc plate 411. The rotating plate 412 is a rectangular structure. The upper end of the rotating plate 412 penetrates the arc plate 411 and is arranged above the arc plate 411. The lower end of the arc plate 411 passes through the square hole 46 and is connected to the lower shell 44 of the slider through a limit pin. The middle part of the rotating plate 412 is connected to the slider 45 through a limit pin; the limit hook 42 is connected to the upper shell 43 of the slider through a limit pin and is arranged at the rear end of the upper shell 43 of the slider; the adjusting locking device 5 is fixed in the lower shell 3 by screws and is arranged below the limit device 4.

The trigger 41 is connected to the slider 45 and the slider lower shell 44 through limit pins respectively. When the trigger 41 moves back and forth in the square hole 46, the slider 45 and the trigger 41 move together so that the slider 45 can move back and forth in the slide groove 47, so that the front end of the trigger 41 can slide out of the slide groove 47 and be fixed to the side groove of the upper CIS shell 1. The locking device 5 is adjusted to abut against the limit hook 42 to control the rotation of the limit hook 42, thereby cooperating with the trigger 41 to realize the functions of automatic locking and manual unlocking.

Preferably, the adjustment locking device 5 includes a hook 51 and a pivot plate 52; the pivot plate 52 is an L-shaped plate and a fixed column 53 is provided at the center of the side; the front half of the hook 51 is L-shaped, and the short side is arranged vertically upward, the rear half of the hook 51 is a horizontal plate, and angled plates 54 are respectively provided on the left and right sides of the upper surface of the horizontal plate, the center of the hook 51 is sleeved on the fixed column 53 through a torsion spring, and the hook 51 is under the reverse force of the torsion spring so that the upper front end of the hook 51 is always higher than the bearing plane of the lower upper shell and is in a horizontal position, when the front end of the hook 51 is subjected to pressure, the hook 51 rotates around the fixed column 53, and the rear end of the hook 51 moves upward to rotate the limit hook 42, unlocking the limit hook 42 and the trigger 41 so that the slider 45 moves forward to lock the upper CIS shell 1, and then the torsion spring returns to its original state to drive the hook 51 to return to its initial position.

Preferably, the upper surface of the bevel plate 54 is in a downward curved arc shape from the front end to the rear end, and the lower end of the limit hook 42 is provided with a chamfer, and the lower end of the limit hook 42 abuts against the rear end of the hook 51. The abutment between the lower end of the limit hook 42 and the rear end of the hook 51 can enable the hook 51 to simultaneously control the rotation of the limit hook 42 when it rotates. The upper surface of the bevel plate 54 is in a downward curved arc shape, so that when the hook 51 rotates, it pushes the limit hook 42 backward so that the limit hook 42 can rotate clockwise, thereby making the limit hook 42 away from the trigger 41 to achieve the effect of automatic locking; at the same time, the lower end of the limit hook 42 and the upper surface of the bevel plate 54 are both in an arc shape, which can reduce the friction between the two and increase the service life of the locking mechanism 2.

Preferably, the limit hook 42 is a rectangular plate and triangular plates 421 are respectively provided on the upper sides thereof, a first limit column 422 is provided above the center of the limit hook 42, a second limit column 441 is provided below the lower shell 44 of the slider, the first limit column 422 and the second limit column 441 are connected by a tension spring, under the action of the tension spring, the limit hook 42 is always in a state of locking the trigger 41 when not subjected to external force, and the lock state with the trigger 41 is released after the limit hook 42 is subjected to force, and then the tension spring returns to its initial state, pulling the limit hook 42 back to its initial position.

Preferably, the upper surfaces of the two triangular plates 421 are provided with oblique grooves 423, and limiting plates 413 are provided on both sides of the trigger 41. The lower surfaces of the limiting plates 413 match the shape of the oblique grooves 423. After unlocking, the trigger 41 is always in an oblique state, and the limiting plates 413 and the oblique grooves 423 are mutually engaged so that the trigger 41 can be always fixed in the unlocked position, thereby improving the stability after unlocking and will not return to the self-locking state under the action of external force when the limiting hook 42 is not rotated.

Preferably, a compression spring is provided at the rear end of the slider 45 and is always in a compressed state. The trigger 41 has not moved to the front end of the square hole 46, the slider 45 is engaged with the side notch of the upper CIS shell 1, the trigger 41 has not moved to the rear end of the square hole 46, the limit plate 413 is located behind the oblique notch 423, and the compression spring is always in a compressed state, so that the slider 45 is always subjected to force so that it can be effectively locked; when the trigger 41 rotates, the limit plate 413 and the oblique notch 423 are already engaged with each other when it has not contacted the two ends of the square hole 46, preventing the trigger 41 from moving to the two ends of the square hole 46 and the limit plate 413 and the oblique notch 423 are still not engaged, and the unlocking and locking effects cannot be achieved.

Preferably, the front end of the slider 45 is chamfered and matches the side notch of the upper CIS shell 1. The chamfer of the front end of the slider 45 can reduce stress concentration and improve the durability of the parts, while preventing the slider 45 from being misaligned with the side notch of the upper CIS shell 1, which makes it impossible to achieve the locking effect.

Preferably, the upper end of the trigger 41 leaks out of the lower shell 3, and the upper surface of the arc plate 411 matches the inner surface of the lower shell 3. The operator can unlock the trigger 41 by pulling the upper end of the trigger 41. At the same time, during the rotation of the trigger 41, the gap between the upper surface of the arc plate 411 and the inner surface of the lower shell 3 is small, reducing dust from entering the scanner.

First, under the action of the tension spring, when the limit hook 42 is not subjected to external force, it is always in a state of locking the trigger 41, and the compression spring behind the slider 45 remains in a compressed state, while the slider 45 is retracted into the slide groove 47; secondly, due to the reverse pressure of the torsion spring, the upper front portion of the hook 51 is always higher than the bearing plane of the lower shell 3, and when the upper CIS shell 1 falls, the hook 51 can be contacted at the first time; when in use, the user drops the upper CIS shell 1 from top to bottom onto the lower shell 3, at which time the bottom surface of the upper CIS shell 1 contacts the upper surface of the front end of the hook 51, and the hook 51 is pressed down, and the hook 51 is fixed with the column 5 3 is the center of rotation clockwise, at this time, the bevel plate 54 at the rear end of the hook 51 abuts against the lower end of the limit hook, and the limit hook 42 is rotated clockwise along the limit pin, at this time, the oblique notch 423 on the upper surface of the limit hook 42 will be disengaged from the limit plates 413 on both sides of the trigger 41, and after the trigger 41 is disengaged, the slider 45 is driven forward by the rebound force of the compression spring, so that the slider 45 extends forward, thereby locking the upper CIS shell 1; when unlocking, the user pulls the trigger 41 back in the opposite direction, and the limit hook 42 locks the trigger 41 again under the action of the tension spring, and the slider 45 is locked in the slide groove 47, and the upper CIS shell 1 can be taken out at this time.

The present invention has been described by the above-mentioned relevant embodiments, however, the above-mentioned embodiments are only examples for implementing the present invention. It must be pointed out that the disclosed embodiments do not limit the scope of the present invention. On the contrary, changes and modifications made without departing from the spirit and scope of the present invention are all within the scope of patent protection of the present invention.
