The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0032] Example 1

[0033] Reference Figure 1~Figure 2 , which is the first embodiment of the utility model, provides a bendable gripping clamp that can replace the hands of maintenance personnel to more easily enter the cabinet for maintenance and avoid the risk of electric shock.

[0035] It should be noted that the clamping plate 101 and the first connecting component 103 are rotatably connected.

[0040] When in use, the second drive component 204 is rotated after being pressed by external force, driving the synchronous belt 203 meshing with the second drive component 204 to move. The movement of the synchronous belt 203 drives the second connection component 201 engaged with the synchronous belt 203 to rotate. The rotation of the second connection component 201 drives the first connection component 103 fixedly connected to the second connection component 201 to swing. After the first connection component 103 swings to a suitable angle, the second drive component 204 is released, and the second drive component 204 is reset and self-locked.

[0041] When clamping, the handle 301 is held and an external force is applied to press the first button 302 provided on the handle 301. The first return spring 304 is deformed under pressure, and the first button 302 drives the third connecting component 306 fixedly connected to the side surface of the first button 302 to tighten. The tightening of the third connecting component 306 starts the first driving component 104. The first driving component 104 starts to drive the first connecting component 103 to move. The movement of the first connecting component 103 drives the splint 101 rotatably connected to the first connecting component 103 to move. The movement of the splint 101 completes the clamping action and releases the external force on the first button 302.

The resetting of the first button 302 drives the third connecting component 306 to reset, and the first driving component 104 stops working and self-locks.

[0042] After the inspection is completed, an external force presses the second button 303 provided on the handle 301, and the second reset spring 305 is deformed under pressure. The second button 303 drives the fourth connecting component 307 fixedly connected to the side surface of the second button 303 to tighten, and the fourth connecting component 307 is tightened to start the first driving component 104. The first driving component 104 starts to drive the first connecting component 103 to move, and the movement of the first connecting component 103 drives the splint 101 rotatably connected to the first connecting component 103 to move. The splint 101 moves to release the clamping, and the external force on the second button 303 is released. The second reset spring 305 releases pressure and deforms to drive the second button 303 to reset. The resetting of the second button 303 drives the fourth connecting component 307 to reset, and the first driving component 104 stops working and self-locks.

[0043] In summary, the beneficial effect of a flexible gripping clamp is that an external force rotates the second driving component 204 to drive the first connecting component 103 to swing and adjust the angle of the clamping unit 100 to bend and fix it to the required position, and the first button 302 and the second button 303 are pressed by external force to control the clamping plate 101 to complete the maintenance, so as to achieve the effect of replacing the hands of the maintenance personnel to more easily enter the cabinet for maintenance and avoid the risk of electric shock.

The high-definition camera 401 transmits the captured image in real time to the display screen 402 electrically connected to the high-definition camera 401 for the user to view.

[0076] In summary, the beneficial effect of a visual maintenance device is that an electrical signal is sent to the lighting lamp 403a through the photosensitive module 403b, and the lighting lamp 403a receives the electrical signal to start lighting, and the captured image is transmitted to the display screen 402 in real time through the high-definition camera 401 for the user to view, so as to improve the maintenance efficiency and protect the safety of maintenance personnel and equipment.

[0077] Importantly, it should be noted that the construction and arrangement of the present application shown in a number of different exemplary embodiments are only exemplary. Although only a few embodiments are described in detail in this disclosure, it should be readily understood by those who refer to this disclosure that many modifications are possible (e.g., the size, scale, structure, shape and proportion of various elements, and parameter values ​​(e.g., temperature, pressure, etc.), mounting arrangements, use of materials, color, directional changes, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in the application. For example, an element shown as integrally formed may be composed of multiple parts or elements, the position of the element may be inverted or otherwise changed, and the nature or number or position of the discrete element may be changed or changed. Therefore, all such modifications are intended to be included in the scope of the present utility model. The order or sequence of any process or method steps may be changed or reordered according to alternative embodiments. In the claims, any "device plus function" clause is intended to cover the structure described herein that performs the function, and is not only structurally equivalent but also an equivalent structure. Without departing from the scope of the present invention, other substitutions, modifications, changes and omissions may be made in the design, operating conditions and arrangement of the exemplary embodiments. Therefore, the present invention is not limited to a specific embodiment, but extends to various modifications that still fall within the scope of the appended claims.

[0078] Additionally, in order to provide a concise description of example embodiments, all features of an actual embodiment may not be described (ie, those features that are not relevant to the best mode presently contemplated for carrying out the invention or those that are not relevant to implementing the invention).

[0079] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0080] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
