Since the partial structure of the mounting buckle 2210 is projected out of the workpiece 3000 in the extending direction of the guide groove 120 when the mounting bracket 2000 is mounted to the workpiece 3000, the above arrangement ensures that the mounting bracket 2000 can be smoothly mounted to the workpiece 3000.

Optionally, as shown in fig. 1, the fixing base 100 is provided with a plurality of guide grooves 120, the extending directions of the plurality of guide grooves 120 are the same, and the plurality of guide grooves 120 are provided on two opposite sides of the fixing base 100 and are opposite to two ends of the limiting groove 110. Above-mentioned setting up conveniently installs a plurality of installing support 2000 on the opposite face of electric core to be located the both ends of electric core respectively, in order to guarantee two electric core position stabilities after the assembly is accomplished.

The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions, improvements, etc. within the spirit and principle of the present invention should be included in the protection scope of the present invention.
