DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Embodiment 1:

[0030] See also Figure 1 and Figure 2 The utility model provides a scanning pen for English translation with adjustable scanning angle. The scanning pen body is an existing structure, mainly including a front shell 17, a rear shell 1 and a scanning head 9. The front shell 17 and the rear shell 1 are snap-fitted and assembled by barbs and hook grooves. It also includes components such as a circuit board, a button, a display screen and a speaker. The connection relationship and functions between the components are all existing, so no further elaboration is given here. The scanning pen body can scan and translate text, and display the translated language on the display screen.

[0031] A pair of guide grooves 5 are provided at the lower ends of the front shell 17 and the rear shell 1. The aligned guide grooves 5 form a guide channel. A guide rod 6 is inserted into the guide channel. A roller 7 is rotatably installed at the lower end of the guide rod 6, so that the guide rod 6 can move back and forth along the guide channel to adjust the extension length.

[0032] An internal threaded tube 14 is provided inside the rear shell body 1, and a linkage block 4 is rotatably installed on the internal threaded tube 14. Long holes 3 are provided at both ends of the linkage block 4, and pins are installed on the tops of the guide rods 6, and the pins are respectively located in the corresponding long holes 3; the two guide rods 6 can be transferred to the linkage block 4 after displacement adjustment in opposite directions (that is, one extends when the other retracts), so that the linkage block 4 swings with the internal threaded tube 14 as the center, and the pins can be appropriately displaced in the long holes 3 without motion interference.

[0033] A scanning head 9 is installed on the lower side of the linkage block 4 through a transmission mechanism, and a butterfly screw 16 is provided on the front shell 17, and the butterfly screw 16 is threadedly assembled with the internal threaded tube 14; after the linkage block 4 swings, it can be transmitted through the transmission mechanism to adjust the swing angle of the scanning head 9, thereby keeping the scanning head 9 facing downward and maintaining the accuracy of text scanning and extraction. After the posture is adjusted, the linkage block 4 can be fixed by tightening the butterfly screw 16 and the internal threaded tube 14. On the contrary, after the butterfly screw 16 is screwed out a little, the linkage block 4 can be rotated and adjusted again.

[0034] Specifically, Figure 2 As shown, the transmission mechanism includes a driving gear 13, a direction-changing gear 11 and an adjusting gear 10; the direction-changing gear 11 and the adjusting gear 10 are rotatably installed in the rear housing 1, a driving gear 13 is provided at the bottom of the linkage block 4, the direction-changing gear 11 is meshingly assembled between the driving gear 13 and the adjusting gear 10, and a scanning head 9 is fixedly installed on the lower side of the adjusting gear 10; when the linkage block 4 swings, it can drive the driving gear 13 to swing, and after the direction-changing gear 11 changes direction, the scanning head 9 on the adjusting gear 10 can swing, so that the rotation directions of the linkage block 4 and the adjusting gear 10 are always kept the same.

[0035] Furthermore, a pair of limit posts 12 are fixedly installed in the rear housing 1 . The limit posts 12 are located below the linkage block 4 and can limit the maximum swing amplitude of the linkage block 4 .

[0036] Specifically, a slot is provided at the bottom center of the front shell 17 and the rear shell 1 , and a perspective protective sheet 8 is installed in the slot. The perspective protective sheet 8 can isolate and protect the scanning head 9 without affecting the scanning work of the scanning head 9 .

[0037] Specifically, the thickness of the linkage block 4, the direction-changing gear 11 and the adjusting gear 10 is H3, the distance between the front housing 17 and the rear housing 1 is H2, and the size of H3 is the same as the size of H2; such a thickness design can enhance the overall strength of small-volume components, and the axial direction of the linkage block 4, the direction-changing gear 11 and the adjusting gear 10 can be limited by the front housing 17 and the rear housing 1 to avoid axial movement and ensure effective transmission.

[0038] Furthermore, the thickness of the internal threaded tube 14 is H1, and the size of H1 is at least 1 mm smaller than the size of H2; because there is a gap of at least 1 mm between the internal threaded tube 14 and the front shell 17, it is convenient to clamp and fix the linkage block 4 when the butterfly screw 16 and the internal threaded tube 14 are tightened.

[0039] The working method of this embodiment is as follows:

[0040] When the tilt angle of the scanning pen needs to be adjusted, the butterfly screw 16 is first loosened so that the two guide rods 6 can be telescopically adjusted along the guide channel. When the scanning pen body is tilted along with the user's hand, the two rollers 7 can be pressed against the plane, so that the two guide rods 6 can be respectively telescopically extended to the appropriate position, and the linkage block 4 can be driven to swing adaptively. After the transmission mechanism is driven, the direction of the scanning head 9 can be adjusted, which is beneficial to adjusting the holding angle and scanning;

[0041] After adjusting to a comfortable angle, tighten the butterfly screw 16 to compress and lock the linkage block 4 between the front shell 17 and the rear shell 1 to prevent the linkage block 4, guide rod 6, transmission mechanism and scanning head 9 from moving freely. Repeat the above operation when adjustment is needed.

[0042] Embodiment 2:

[0043] This embodiment includes all the technical features of the embodiment 1, and further adds the following technical features: a power assist mechanism for assisting the guide rod 6 in resetting is provided in the rear housing 1 .

[0044] Specifically, Figure 3 and Figure 4 As shown, the assist mechanism includes a tension spring 2 and a structural rib 15; the structural rib 15 is symmetrically arranged inside the rear shell 1, the upper end of the guide rod 6 is connected to the structural rib 15 through the tension spring 2, and the upper end of the guide rod 6 and the structural rib 15 are both provided with a through hole for hanging the tension spring 2; the setting of the tension spring 2 can make the guide rod 6 have the same, upward force, which is conducive to the self-resetting of the guide rod 6.

[0045] Furthermore, the front and rear side surfaces of the linkage block 4 are provided with a first anti-slip groove, and the inner surfaces of the front shell 17 and the rear shell 1 located at the linkage block 4 are provided with a second anti-slip groove; when the front shell 17 and the rear shell 1 are clamped on the linkage block 4, the friction force can be increased by the first anti-slip groove and the second anti-slip groove, thereby improving the clamping and fixing effect.

[0046] The working method of this embodiment is as follows:

[0047] When the tilt angle of the scanning pen needs to be adjusted, first loosen the butterfly screw 16, and the two guide rods 6 automatically reset along the guide channel due to the setting of the tension spring 2. When the scanning pen body is tilted with the user's hand, the two rollers 7 can be pressed against the plane, so that the two guide rods 6 are respectively extended to the appropriate position, and the linkage block 4 is driven to swing adaptively. After the transmission mechanism is driven, the direction of the scanning head 9 can be adjusted, which is beneficial to adjust the holding angle and also beneficial to scanning;

[0048] After adjusting to a comfortable angle, tighten the butterfly screw 16. At this time, the first anti-slip pattern and the second anti-slip pattern are in contact, which improves the clamping and fixing effect. The linkage block 4 between the front shell 17 and the rear shell 1 can be pressed and locked to prevent the linkage block 4, guide rod 6, transmission mechanism and scanning head 9 from moving freely. Repeat the above operation when it needs to be adjusted again.
