DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.

The key 30 is linked with the jog switch 40 through the coupling 50. When the key 30 is pressed alone, the coupling 50 cannot transmit the action of the key 30 to the jog switch 40, thus avoiding accidental touch. Compared with the cover plate structure, the influence on holding is small. Since the hand grip 20 is located on the side and the key 30 is located on the front, accidental touch caused by bumping cannot be triggered at the same time.

[0036] Please refer to Figures 1-4 The device also comprises a rubber membrane key plate 60, and the key 30 is integrated on the rubber membrane key plate 60. The rubber membrane key plate 60 is integrated with a plurality of keys 30 and has the advantages of good integrity, low cost, waterproofness and dustproofness.

[0037] Please refer to Figures 1-4 The housing 10 is fixedly connected with a panel 70, and the panel 70 is provided with through holes corresponding to the keys 30. The rubber membrane is attached to the inner wall of the panel 70. The rubber membrane is attached to the inner wall of the panel 70, and only the key 30 protrudes from the panel 70. The panel 70 is used to protect and fix the rubber membrane key plate 60.

[0038] Please refer to Figures 1-4 The device also comprises a circuit board 80, and the jog switch 40 is integrated on the circuit board 80, which is fixedly connected with the housing 10. All the jog switches 40 are integrated on the circuit board 80 and correspond to the rubber membrane key plate 60.

[0039] Please refer to Figures 1-4 The coupling member 50 comprises a sliding plate 51, a sliding groove is formed on the shell 10, the sliding plate 51 is in sliding connection with the shell 10 in the sliding groove, the sliding plate 51 is arrayed with a support rod 52, the support rod 52 is in elastic connection with the sliding plate 51, and the two ends of the support rod 52 are in abutment with the key 30 and the jog switch 40 respectively. The sliding plate 51 moves in the sliding groove, so that the support rod 52 can be moved between the key 30 and the jog switch 40, when the key 30 is pressed, the jog switch 40 can be pressed through the support rod 52 to realize triggering, when the sliding plate 51 moves away, the support rod 52 is away from the key 30, when the key 30 is pressed, the key 30 is pressed empty, so that the jog switch 40 cannot be triggered, the protection of the key 30 is realized, and the mistaken triggering of the key 30 is avoided.

[0040] Please refer to Figures 1-4 The coupling member 50 further comprises an elastic connecting rod 53, the two ends of the connecting rod 53 are fixedly connected with the support rod 52 and the sliding plate 51 respectively. The connecting rod 53, the support rod 52 and the sliding plate 51 are integrally formed, the support rod 52 is elastically connected to the sliding plate 51 through the connecting rod 53, so that the connecting rod 53 can be pressed and can also move together with the sliding plate 51.

[0041] Please refer to Figures 1-4 The coupling member 50 further comprises a push rod 54, the push rod 54 is fixedly connected with the sliding plate 51, and the push rod 54 is in abutment with the hand holding member 20. After the hand holding member 20 is held, the sliding plate 51 is pushed to move through the push rod 54, and then the coupling member 50 is triggered to realize the linkage of the key 30 and the jog switch 40.

[0042] Please refer to Figures 1-4 The coupling member 50 further comprises an elastic sheet 55, the elastic sheet 55 is installed on the shell 10, and the outer end of the elastic sheet 55 is in abutment with the push rod 54. The pushing action of the elastic sheet 55 on the push rod 54 makes the connecting plate have a restoring tendency, so that the support rod 52 on the connecting plate is in a misaligned state in the initial state, thereby realizing the protection of the case.

[0043] Please refer to Figures 1-4 The hand holding member 20 comprises a holding rod 21, one end of the holding rod 21 is hingedly connected with the shell 10, and the other end of the holding rod 21 is fixedly connected with a push block 22, and the push block 22 is in slanting surface sliding connection with the push rod 54. The upper end of the holding rod 21 is easy to exert force, and the lower end close to the hinged point is not easy to exert force, so when moving, the lower end can be held, so that the unlocking member is not easy to be triggered, when holding operation is needed, the upper end can be held to operate the key 30, when the holding rod 21 is deflected, the slanting surface on the push block 22 is used to push the push rod 54 to move downward, so as to push the sliding plate 51 downward, and the linkage effect is realized.

[0044] Please refer to Figures 1-4The hook 23 on the pushing block 22 hooks the pushing rod 54. When the elastic piece 55 pushes the sliding plate 51 to the top, i.e. the initial position, the pushing block 22 and the holding rod 21 are pushed to the two sides, the hook 23 on the pushing block 22 hooks the pushing rod 54, thereby providing the limit for the holding rod 21.

[0045] The working principle of the area measuring device for land resource planning is as follows: in the initial state, the elastic piece 55 pushes the sliding plate 51 to the top, the pushing block 22 and the holding rod 21 are pushed to the two sides, the hook 23 on the pushing block 22 hooks the pushing rod 54, thereby maintaining the posture of the holding rod 21, and the support rod 52 on the sliding plate 51 is offset from the button 30, so that when the button 30 is pressed, the button 30 is pressed empty, thereby cannot trigger the momentary switch 40, realizing the protection of the button 30, avoiding the accidental touch of the button 30. When the operation input part needs to be operated, both hands or one hand hold the two holding rods 21, the pushing block 22 on the holding rod 21 pushes the pushing rod 54 and the sliding plate 51 downward by the inclined surface, so that all the support rods 52 on the sliding plate 51 move to between the button 30 and the momentary switch 40, and when the thumb presses the button 30, the momentary switch 40 is pressed through the support rod 52, realizing the trigger. It should be noted that, according to the above, when the button 30 is pressed alone, the coupling piece 50 cannot transmit the action of the button 30 to the momentary switch 40, thereby avoiding the accidental touch. Compared with the cover plate structure, the influence on holding is small. Since the hand holding piece 20 is located on the side surface and the button 30 is located on the front surface, when the button 30 is accidentally touched, the button 30 cannot be triggered at the same time, thereby avoiding the accidental touch caused by accidental touch.

[0046] The above is only an embodiment of the present application and does not limit the protection scope of the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, improvement or equivalent replacement made within the spirit and principle of the present application shall be included in the protection scope of the present application. It should be noted that: similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.
