Since the fixing device 4 is disposed at the lower portion of the connecting plate 33 at both sides, and the supporting device 6 cannot be disposed, a certain improvement is required to be made on the driving link 44, as shown in fig. 9, a spring six 442 is disposed at one end of the first chute 411 close to the telescopic bracket 34, and a connecting rod 443 rotatably connected to the outer surface of the second telescopic link 342 at both sides is disposed at one end of the spring six 442 close to the telescopic bracket 34.
Specifically, when the worker applies a force to the connecting device 3 and the fixing device 4, when the positioning block 41 moves to the side close to the fixing plate 2, the second transmission rod 441 rotates along with the positioning block 41 when the positioning block 41 and the connecting device 3 move to the side close to the fixing plate 2, but no displacement occurs, so that the second expansion rod 342 located at two sides is lifted up by the connecting rod 443 to be in contact with the bottom of the electric element 5, and after the connecting rod 443 is in contact with the surface of the electric element 5, the positioning block 41 still moves continuously, at this time, the spring six 442 is compressed, so that the spring six 442 can apply a force to the second expansion rods 342 located at two sides, and the second expansion rods 342 located two sides can be in close contact with the surface of the electric element 5.
In summary, the specific embodiments thereof are as follows: in the moving process that the fixing device 4 fixes the connecting device 3 and the electric element 5 on the fixing plate 2 through the fixing piece 7, the supporting device 6 can push the second telescopic rod 342 to be in contact with the bottom surface of the electric element 5, so that the fixing strip 31 can be in close contact with the bottom surface of the electric element 5, and shaking can be avoided under certain conditions, and the electric element 5 is damaged.
It should be noted that, the specific installation manner and the circuit arrangement connection manner of the electrical component 5 and the control manner thereof adopted in the first embodiment are all conventional designs in the prior art, and are not described in detail in the present invention.
The foregoing has shown and described the basic principles and main features of the present invention and the advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims. The scope of the invention is defined by the appended claims and equivalents thereof.
