DETAILED DESCRIPTION

[0029] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0030] REFERENCE Figure 1 , Figure 2 and Figure 4The utility model provides an embodiment: a kind of fuse assembly, including fixed plate 1 and fuse body 14, fixed plate 1 top is fixedly connected with support plate 17, fixed plate 1 top is fixedly connected with support frame 15, support plate 17 side wall is provided with adjusting mechanism, fixed plate 1 top is provided with mounting mechanism, for the fixation of fuse body 14;Adjusting mechanism includes sleeve 2, sleeve 2 side wall is fixedly connected in fuse body 14 side wall, sleeve 2 inside is slidably connected with clamping plate one 3, sleeve 2 inside is provided with first spring 4, sleeve 2 inside is fixedly connected with clamping plate two 5, clamping plate two 5 inside is slidably connected with slide rod 6, slide rod 6 is fixedly connected with clamping plate one 3, slide rod 6 side wall is fixedly connected with fixed ring 7, slide rod 6 is slidably connected in fuse body 14, fuse body 14 is slidably connected between clamping plate one 10 and clamping plate two 11, first spring 4 one end is fixedly connected in sleeve 2 inside, first spring 4 other end is in close contact with clamping plate one 3, clamping plate one 3 is engaged with clamping plate two 5, slide rod 6 side wall is fixedly connected with pressing plate 16;

[0031] When using the device, the angle of the connecting plate 8 can be adjusted flexibly to adapt to different installation spaces and usage requirements. By pressing the pressing plate 16, the slide rod 6 drives the clamping plate one 3 to slide into the sleeve 2, while compressing the first spring 4, generating a certain compression force. When the clamping plate one 3 and the clamping plate two 5 are separated, the connecting plate 8 loses the restriction, and the user can rotate the pressing plate 16 to drive the slide rod 6 to rotate inside the sleeve 2, thereby changing the angle of the connecting plate 8. This process is not only convenient and efficient, but also ensures the smoothness and stability of the angle adjustment. When the angle adjustment of the connecting plate 8 is completed, the pressing plate 16 is released, and the first spring 4 quickly recovers due to the loss of pressure, driving the clamping plate one 3 to reset, so that the clamping plate one 3 and the clamping plate two 5 are re-engaged, ensuring the firm locking of the angle of the connecting plate 8, avoiding any looseness or instability during the adjustment process, thereby providing reliable protection for the stable use of the device. This design not only improves the convenience of operation, but also enhances the safety and service life of the device.

[0032] Referring to Figures 2-3 The mounting mechanism includes a connecting plate 8, which is fixedly connected to the side wall of the fixed ring 7. The side wall of the connecting plate 8 is fixedly connected with a fixed frame 9. The outer wall of the fixed frame 9 is rotatably connected with a clamping plate one 10. The outer wall of the fixed frame 9 is rotatably connected with a clamping plate two 11. The side wall of the clamping plate two 11 is slidably connected inside the clamping plate one 10. The clamping plate one 10 and the clamping plate two 11 are both arc-shaped. The side wall of the clamping plate one 10 and the clamping plate two 11 is fixedly connected with a side plate 12. The connecting plate 8 and the side plate 12 are fixedly connected with a second spring 13.

[0033] When the angle adjustment of the connecting plate 8 is completed and locked, the first clamping plate 10 and the second clamping plate 11 are forced to deflect to both sides under the pressure by applying a pressing force to the fuse body 14 in the direction of the connecting plate 8, and the second spring 13 is extruded and deformed to store a certain amount of elastic energy. As the fuse body 14 gradually slides to the cavity between the first clamping plate 10 and the second clamping plate 11, the extrusion force on the clamping plate gradually decreases until it disappears completely, at which time the second spring 13 quickly resets to release the stored energy, pushing the first clamping plate 10 and the second clamping plate 11 back to the initial state, firmly clamping the fuse body 14. The reset first clamping plate 10 and the second clamping plate 11 can provide stable clamping force under the support of the second spring 13, preventing the fuse body 14 from loosening or shifting during use. The entire design cleverly utilizes the deformation and reset characteristics of the spring to achieve automatic fixing of the fuse body 14, not only improving the operation convenience, but also enhancing the safety and reliability of the equipment.

[0034] Working principle: When using the device, the angle of the connecting plate 8 can be adjusted according to the size of the installation space, the first clamping plate 3 is slid into the sleeve 2 by pressing the pressing plate 16, and the first spring 4 is extruded, when the first clamping plate 3 and the second clamping plate 5 are separated, the connecting plate 8 loses the restriction, that is, the pressing plate 16 is rotated to drive the sliding rod 6 to rotate inside the sleeve 2, thereby changing the angle of the connecting plate 8, when the angle is determined, stop pressing the pressing plate 16, at this time the first spring 4 loses the pressure to drive the first clamping plate 3 to reset, and the first clamping plate 3 and the second clamping plate 5 are re-engaged to lock the angle of the connecting plate 8;

[0035] When the angle adjustment of the connecting plate 8 is completed, the fuse body 14 is placed between the first clamping plate 10 and the second clamping plate 11, and then it is pressed in the direction of the connecting plate 8, so that the first clamping plate 10 and the second clamping plate 11 are extruded and deflected to both sides, and the second spring 13 is deformed, when the fuse body 14 moves to the cavity between the first clamping plate 10 and the second clamping plate 11, the extrusion force on the first clamping plate 10 and the second clamping plate 11 disappears, at this time the second spring 13 begins to reset, pushing the first clamping plate 10 and the second clamping plate 11 to the initial state, thereby completing the fixation of the fuse body 14.

[0036] Finally, it should be pointed out that the above-mentioned is only the preferred embodiment of the present application, and is not used to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features can be replaced, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
