[0050] Please refer to Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 And Figure 7 Among them Figure 3 is the perspective view of the single-hand operation type trigger device of the first embodiment of the application, Figure 4 is the perspective exploded view of the single-hand operation type trigger device of Figure 3 , Figure 5 is the perspective view of the single-hand operation type trigger device of Figure 3 from another angle, Figure 6 is the sectional view along the line A-A of Figure 3 , Figure 7 is the sectional view along the line B-B of Figure 3 . As shown in the figure, the single-hand operation type trigger device 1 of the embodiment includes a switch assembly 10, a base assembly 20, a pressing assembly 30 and a limiting and pressing mechanism 40. The single-hand operation type trigger device 1 also includes a device accommodating assembly 50 for accommodating electronic devices, such as portable scanners. Here, the first direction L1 is defined as the vertical direction, and the second direction L2 and the third direction L3 are defined as two directions perpendicular to each other in the horizontal plane, i.e. the first direction L1 is perpendicular to the second direction L2 and the third direction L3. The second direction L2 of the embodiment corresponds to the long side direction of the base assembly 20 and the pressing assembly 30, and the third direction L3 of the embodiment corresponds to the short side direction of the base assembly 20 and the pressing assembly 30.

[0051] The switch assembly 10 comprises a first contact member 11, a second contact member 12, a first wire 13 electrically connected to the first contact member 11, and a second wire 14 electrically connected to the second contact member 12. The first contact member 11 and the second contact member 12 are disposed on a circuit board 15. In this embodiment, the first contact member 11 is an arc-shaped spring member and protrudes away from the second contact member 12 along a first direction L1. The second contact member 12 is a contact structure disposed on the circuit board 15. The first contact member 11 is disposed above the second contact member 12 along the first direction L1. The edge of the first contact member 11 is disposed on the circuit board 15, and the arc-shaped spring of the first contact member 11 is at a predetermined distance from the second contact member 12. The first wire 13 and the second wire 14 are electrically connected to the circuit board 15 and form electrical connections with the first contact member 11 and the second contact member 12, respectively, via the circuit board 15. The first contact member 11 is moved downward along the first direction L1 to contact the second contact member 12, so that the first wire 13 and the second wire 14 form a conduction state. Alternatively, the first contact member 11 is moved upward along the first direction L1 to separate from the second contact member 12, so that the first wire 13 and the second wire 14 form an open state.

[0052] The base assembly 20 comprises a support 21 and a plurality of first extension members 22. The support 21 supports the circuit board 15, i.e., supports the first contact member 11 and the second contact member 12. The plurality of first extension members 22 extend from the edge of the support 21 toward the switch assembly 10 along the first direction L1, and the plurality of first extension members 22 are disposed on opposite sides of the support 21 in pairs at least in the second direction L2 and the third direction L3. In this embodiment, the plurality of first extension members 22 are connected to each other to form an extended peripheral wall.

[0053] The support 21 comprises a support body 211, a plurality of support ribs 212, a plurality of positioning posts 213 and a plurality of buckling members 214. The support body 211 is a bottom plate structure, and the plurality of support ribs 212 are arranged on the support body 211 and extend in the second direction or / and the third direction to support the circuit board 15, i.e. support the first contact component 11 and the second contact component 12. The plurality of positioning posts 213 extend away from the support body 211 and the support ribs 212 in the first direction L1, and the circuit board 15 has a plurality of positioning holes 151. The plurality of positioning posts 213 pass through the plurality of positioning holes 151, so that the circuit board 15, the first contact component 11 and the second contact component 12 are limited in the second direction L2 and the third direction L3 on the support 21. The plurality of buckling members 214 are arranged on opposite sides of the plurality of support ribs 212 and extend away from the support body 211 in the first direction L1. The ends of the buckling members 214 are barb-shaped structures and abut against the circuit board 15, so that the circuit board 15, the first contact component 11 and the second contact component 12 are limited in the first direction L1 on the support 21. In this way, the circuit board 15 is limited in the first direction L1, the second direction L2 and the third direction L3 by the support ribs 212, the positioning posts 213 and the buckling members 214.

[0054] The support 21 further comprises two wire grooves 215 formed between the plurality of support ribs 212 and the plurality of buckling members 214, and a through hole 216 formed between two adjacent first extension members 22. In the embodiment, the through hole 216 is located on one side in the second direction L2, and the first wire 13 and the second wire 14 enter the two wire grooves 215 of the support 21 through the through hole 216. In this way, the circuit board 15 mounted on the support ribs 212 can cover and abut against the first wire 13 and the second wire 14 at the same time. The circuit board 15 is limited in the first direction L1, the second direction L2 and the third direction L3 by the support ribs 212, the positioning posts 213 and the buckling members 214, and the first wire 13 and the second wire 14 are also limited in the first direction L1 at the same time. Therefore, the support 21 also plays a role of wire arrangement for the first wire 13 and the second wire 14.

[0055] The pressing assembly 30 comprises a pressing body 31, an abutting member 32 and a plurality of second extension members 33. The pressing body 31 is a plate structure, the abutting member 32 is arranged on the surface of the pressing body 31 and abuts against the first contact component 11 in the first direction L1. In the embodiment, the abutting member 32 is columnar and arranged at the center of the pressing body 31, and abuts against one contact position of the first contact component 11. The plurality of second extension members 33 are arranged on opposite sides of the pressing body 31 in the second direction L2 and the third direction L3 and extend towards the base assembly 20 in the first direction L1.

[0056] In this embodiment, the size of the pressing body 31 is smaller than the size of the support member 21. Therefore, when the pressing assembly 30 is assembled with the base assembly 20, the second extension member 33 is closer to the switch assembly 10 than the first extension member 22. That is, the second extension member 33 is located inside the first extension member 22.

[0057] A limiting and pressurizing mechanism 40 is disposed on a plurality of first extensions 22 and a plurality of second extensions 33. The limiting and pressurizing mechanism 40 includes a plurality of abutting protrusions 41 and a plurality of abutting slots 42. The plurality of abutting protrusions 41 abut against the hole walls of the plurality of abutting slots 42 in a first direction L1. In this embodiment, the plurality of abutting protrusions 41 are respectively disposed on a plurality of second extensions 33 and the plurality of abutting slots 42 are respectively disposed on a plurality of first extensions 22. The abutting protrusions 41 are hook-shaped. Since the second extensions 33 are closer to the switch assembly 10 than the first extensions 22, that is, the second extensions 33 are located inside the first extensions 22, the abutting protrusions 41 extend from the side of the abutting slots 42 closest to the switch assembly 10 to the side furthest from the switch assembly 10. In this embodiment, the abutting protrusions 41 abut against the slot wall of the abutting slots 42 on the side furthest from the support body 211, and there is a retraction distance D between the end of the second extension 22 and the support body 211.

[0058] Please refer to the following: Figure 8 , it is Figure 7 This is a schematic diagram of the pressing body of the pressing component applying force to one side. When the user applies force to one side of the pressing body 31, it is defined as the force-applying side P1. The side of the pressing body 31 opposite to the force-applying side is defined as the abutting side P2. At least one abutting protrusion 41 of the abutting side P2 remains abutting against the wall of the abutting slot 42, so that the user can continuously increase the applied force and eventually cause the abutting member 32 to push the first contact member 11 to move along the first direction L1 and contact the second contact member 12.

[0059] Please refer to the following: Figure 9 , it is Figure 3 A cross-sectional view along line CC. The device receiving assembly 50 includes a receiving member 51, an electrical connector 52, and a locking and positioning member 53. The receiving member 51 has a bottom wall 511 and an outer peripheral wall 512. The bottom wall 511 is connected to the outer peripheral wall 512 to form a receiving groove 513. A locking groove 514 is formed in the outer peripheral wall 512. The receiving groove 513 and the locking groove 514 open on opposite sides of the receiving member 51. The inner surface of the outer peripheral wall 512 of the receiving member 51 has two slots 511a, so that the locking groove 514 communicates with the receiving groove 513.

[0060] The electric connector 52 connects the first wire 13 and the second wire 14 and is combined with the snap positioning member 53. The electric connector 52 comprises an electric connector body 521 and two electric connection structures 522 arranged on the surface of the electric connector body 521. The snap positioning member comprises a combination groove 533 formed on the surface of the snap positioning member 53 close to the accommodating groove 513 of the accommodating member 51, the electric connector 52 is positioned in the combination groove 533, and the two electric connection structures 522 extend into the accommodating groove 513.

[0061] The snap positioning member 53 is snapped into the snap groove 514 and positioned in the accommodating member 51. The snap groove 514 comprises two first snap end portions 5141 arranged on opposite sides thereof, and the snap positioning member 53 comprises two second snap end portions 531 arranged on opposite sides thereof and a stress deformation notch 532 between the two second snap end portions. The two first snap end portions 5141 and the two second snap end portions 531 are step-shaped structures matched with each other, and the distance between the two first snap end portions 5141 is smaller than the distance between the two second snap end portions 531. Therefore, when the snap positioning member 53 is snapped into the snap groove 514, the second snap end portion 531 away from the stress deformation notch 532 is first snapped into one first snap end portion 5141 of the snap groove 514, and then the snap positioning member 53 is rotated to make the second snap end portion 531 close to the stress deformation notch 532 snap into the corresponding first snap end portion 5141, the snap positioning member 53 generates stress deformation at the stress deformation notch 532, so that the snap positioning member 53 is snapped into the snap groove 514. The second snap end portion 531 close to the stress deformation notch 532 of the snap positioning member 53 forms a guide inclined surface 5311, when the second snap end portion 531 is pushed into the snap groove 514, the guide inclined surface 5311 abuts against the end edge of the first snap end portion 5141 to smoothly push the stress deformation notch 532 to generate stress deformation, and finally make the second snap end portion 531 snap into the corresponding first snap end portion 5141.

[0062] As shown in Figure 4 and Figure 5 The device accommodating assembly 50 further comprises a wire positioning member 54, and the accommodating member 51 further comprises a wire positioning groove 515 formed on the bottom wall 511 of the accommodating member 51. The first wire 13 and the second wire 14 are combined with the wire positioning member 54, for example, in an integrated structure formed by an injection molding process. The part of the electric connector 52 connected with the first wire 13 and the second wire 14 abuts against the wire positioning member 54, and the wire positioning member 54 is combined with the wire positioning groove 515 through a structure matched in shape.

[0063] Please refer to Figures 10 to 16, which are the drawings of the single-hand trigger device of the second embodiment of the present application. The present embodiment has some same structure as the first embodiment, so the same components are given the same symbols and the description thereof is omitted. The difference between the present embodiment and the first embodiment is that the size of the pressing body 31 of the present embodiment is larger than the size of the support 21, so when the pressing assembly 30 is combined with the base assembly 20, the second extension 33 is farther away from the switch assembly 10 than the first extension 22, i.e. the first extension 22 is inside the second extension 33. In addition, a plurality of abutting protrusions 41 are respectively arranged on the plurality of first extensions 22 and a plurality of abutting grooves 42 are respectively arranged on the plurality of second extensions 33, and because the first extension 22 is inside the second extension 33, the abutting protrusion 41 extends from the side of the abutting groove 42 close to the switch assembly 10 to the side far away from the switch assembly 10, and the abutting protrusion 41 also abuts on the hole wall of the abutting groove 42 in the first direction L1. The abutting protrusion 41 of the present embodiment abuts on the hole wall of the abutting groove 42 close to the support 21, and the end of the first extension 22 has a retreat distance with the pressing body 31.

[0064] As shown in Figure 15 , when the user applies force to one side of the pressing body 31, which is defined as the force application side P1, and the side of the pressing body 31 opposite to the force application side is defined as the abutting side P2, at least one abutting protrusion 41 of the abutting side P2 keeps abutting on the hole wall of the abutting groove 42, so that the user can continuously increase the force until the abutting member 32 pushes the first contact component 11 to move along the first direction L1 to contact the second contact component 12.

[0065] The single-hand trigger device of the present application, by arranging a plurality of first extensions on the opposite sides of the support of the base assembly and arranging a plurality of second extensions on the opposite sides of the pressing body of the pressing assembly, the plurality of first extensions correspond to the plurality of second extensions, and the limiting and pressing mechanism is arranged on the plurality of first extensions and the plurality of second extensions, and the plurality of abutting protrusions of the limiting and pressing mechanism respectively abut on the hole walls of the plurality of abutting grooves. When the user applies force to the force application side of one side of the pressing body, at least one abutting protrusion of the abutting side of the pressing body opposite to the force application side keeps abutting on the hole wall of the abutting groove, so that even if the force is applied to the position close to the edge of the pressing body, the force application side of the pressing body will not directly move until being stopped by the support, and the user can continuously increase the force until overcoming the required force of the first contact component, so that the abutting member pushes the first contact component to move to contact the second contact component. In this way, the dead point of operation can be avoided in all directions to achieve omnidirectional triggering.

[0066] The above embodiments are only illustrative of the principles of the present application and its effects, and are not intended to limit the present application. Any modification or change made by any person skilled in the art without departing from the spirit and scope of the present application shall be covered by the claims of the present application.
