[0027] A linkage component 2 installed in the top shell 13 for linking the stretching component 18 to stretch the plum blossom contact; an impact component 3 connected to the top shell 13 to assist in the assembly of the plum blossom contact, wherein: the linkage component is respectively connected to multiple linkage rods 186, and the linkage component 2 unfolds multiple stretching plates 184 through multiple linkage rods 186 and multiple guide plates 185, and the multiple stretching plates 184 stretch the ends of the plum blossom contacts attached to their outer surfaces.

[0028] In a specific implementation, the linkage assembly 2 is installed inside the main shell 1, the impact mechanism 3 is installed on the side of the main shell 1, the handle 11 is installed on the side of the top shell 13, the baffle 12 is installed on the side of the handle 11, and the side of the top shell 13 is provided with a slot 15 for accommodating the clamping assembly 27. The bottom surface of the open shell 16 is provided with a guide groove 17, and the side of the open shell 16 is provided with an open assembly 18.

[0029] Furthermore, the opening assembly 18 further includes: a plurality of moving wheels 187 connected to the plurality of linkage rods 186 in one-to-one correspondence; the linkage assembly 2 includes: a linkage plate 22, and the plurality of moving wheels 187 are respectively abutted against the linkage plate 22. Among them: the plurality of moving wheels 187 roll along the linkage plate 22 and lose support, and the reset spring 183 links the plurality of opening plates 184 to shrink and reset, and the plum blossom contact is taken out.

[0030] Preferably, the linkage assembly 2 also includes: a rotating rod 21 connected to one side of the linkage plate 22, a limiting shaft 23 connected to the other side of the linkage plate 22, a limiting rod 24 connected to the other side of the linkage plate 22, and a rotating handle 26 connected to the end of the rotating rod 21.

[0031] Among them: the rotating rod 21 is rotatably installed inside the top shell 13, and its top end is connected to the support frame 14 on the end side of the top shell 13; the bottom of the open shell 16 is provided with a guide groove 17, the limit rod 24 is installed in the guide groove 17, and the limit shaft 23 is connected to the open shell 16.

[0032] Preferably, an anti-slip pad 25 is installed on the end surface of the linkage plate 22 .

[0033] During implementation, the entire device is held by the handle 11, one end of the guide groove 17 of the main housing 1 is placed inside the plum blossom contact, and the moving wheel 187 slides along the surface of the linkage plate 22 through the action of the linkage assembly 2, and the moving wheel 187 drives the expansion plate 184 to expand, at which time one end of the plum blossom contact on the outer surface of the expansion plate 184 is expanded, so that the entire plum blossom contact is expanded to form a truncated cone. When the plum blossom contact is installed, the linkage assembly 2 is rotated to make the moving wheel 187 lose support, and under the pull of the reset spring 183, the expansion plate 184 returns to the retracted state, and the device can be quickly taken out.

[0034] The principle of the linkage assembly 2 making the moving wheel 187 slide along the surface of the linkage plate 22 is as follows: the rotating rod 21 is rotated by turning the handle 26, and the linkage plate 22 on the bottom of the rotating rod 21 also rotates accordingly. Due to the special shape of the linkage plate 22, the moving wheel 187 will be squeezed when it rotates, causing the moving wheel 187 to roll along the side of the linkage plate 22, driving the expansion plates 184 in four directions to unfold. The function of the limit shaft 23 is to limit the position of the linkage plate 22 to make its rotation more stable. Since the limit rod 24 will slide inside the guide groove 17, the rotation angle and direction of the linkage plate 22 are limited.

[0035] Furthermore, the linkage assembly 2 also includes: a clamping assembly 27 for clamping the outer surface of the plum blossom contact.

[0036] The clamping assembly 27 includes: two supporting seats 275 respectively fastened to the opposite sides of the top shell 13, two fixing buckles 271 respectively movably connected to the rotating rod 21, two transmission rods 272 connected to the two fixing buckles 271 in a one-to-one correspondence, two connecting buckles 273 connected to the two transmission rods 272 in a one-to-one correspondence, and two clamping arms 274. The opposite ends of the two clamping arms 274, the two connecting buckles 273 and the two supporting seats 275 are connected in a one-to-one correspondence, wherein: the rotating rod 21 rotates, driving the fixing buckle 271 to change its direction, squeezing the transmission rod 272 to move to one side, so that the top surface of the clamping arm 274 is subjected to thrust.

[0037] Preferably, a clamping plate 276 is provided at the end of the clamping arm 274 , and a rubber pad 277 is fixedly connected to the side of the clamping plate 276 .

[0038] During implementation, when the rotating rod 21 rotates, the clamping assembly 27 is driven to move, and the clamping assembly 27 clamps and fixes the outer surface of the plum blossom contact to improve the stability during replacement. Specifically, the rotating rod 21 rotates to drive the two fixing buckles 271 to change their directions, respectively squeezing the two transmission rods 272 to move to one side, so that the top surface of the clamping arm 274 is subjected to a thrust, thereby driving the clamping plate 276 to clamp the plum blossom contact.

[0039] Furthermore, the impact assembly 3 includes: a side shell 31, a spring rod 32, a slider 33 and an impact soft head 37, and the spring rod 32, the slider 33 and the impact soft head 37 are connected in sequence, wherein: the spring rod 32 drives the slider 33 to slide inside the side shell 31, and the slider 33 links the impact soft head 37 to impact the side of the plum blossom contact.

[0040] Preferably, the impact assembly 3 also includes: a limit member 35 installed on the side shell 31, a toggle rod 34 movably connected to the limit member 35 and a clamping rod 36 installed in the limit member 35, the clamping rod 36 is detachably connected to the toggle rod 34, and the toggle rod 34 is connected to the slider 33.

[0041] In this embodiment, the slider 33 is movably connected to the inside of the side shell 31, and a toggle rod 34 is fixedly connected to the side of the side shell 31. The top of the outer surface of the toggle rod 34 is movably connected to a limiting member 35. The limiting member 35 is fixedly connected to the top of the side of the side shell 31. A clamping rod 36 is clamped inside the top surface of the limiting member 35. The bottom end of the outer surface of the clamping rod 36 is clamped inside the side of the toggle rod 34. The bottom surface of the slider 33 is fixedly connected to an impact soft head 37.

[0042] During implementation, the spring rod 32 drives the slider 33 to slide inside the side shell 31. After the plum blossom contact is installed, the clamping rod 36 can be pulled out. At this time, under the pushing action of the spring rod 32, the slider 33 drives the impact soft head 37 to impact the side of the plum blossom contact to prevent the plum blossom contact from being installed in a suitable position and affecting normal use. After use, the slider 33 can be moved to shrink the spring rod 32, and the moving rod 34 can be inserted into the inside of the limiter 35 and fixed by the clamping rod 36 for reuse.

[0043] When the replacement device for the plum blossom contact of the small current switch trolley in this embodiment is implemented, the entire device is held by the handle 11, one end of the guide groove 17 of the main shell 1 is placed inside the plum blossom contact, and the moving wheel 187 is made to slide along the surface of the linkage plate 22 through the action of the linkage component 2. The moving wheel 187 drives the expansion plate 184 to expand. At this time, one end of the plum blossom contact on the outer surface of the expansion plate 184 is expanded, so that the entire plum blossom contact is expanded into a truncated cone shape, which is convenient for disassembly and installation.

[0044] When the rotating rod 21 rotates, the clamping assembly 27 is driven to move, and the clamping assembly 27 clamps and fixes the outer surface of the plum blossom contact to improve the stability during replacement. Specifically, the rotating rod 21 rotates to drive the two fixing buckles 271 to change their directions, respectively squeezing the two transmission rods 272 to move to one side, so that the top surface of the clamping arm 274 is subjected to a thrust, thereby driving the clamping plate 276 to clamp the plum blossom contact.

[0045] It can be understood that: when the plum blossom contact is installed, the linkage assembly 2 is rotated to make the moving wheel 187 lose its support, and under the pull of the return spring 183, the support plate 184 returns to the retracted state, and the device can be quickly taken out.
