Detailed Description

Reference numerals in the drawings of the specification include: the relay comprises a relay 1, a relay base 2, a fork shearing frame 3, a clamping block 4, an L-shaped clamping groove 5, a first convex clamping groove 6, a first H-shaped sliding block 7, a through hole 8, an L-shaped clamping block 9, a second H-shaped sliding block 10, a second convex clamping groove 11 and a limiting hole 12.

Examples

The embodiment is basically as shown in the attached figure 1: a compact relay includes a relay 1, a relay base 2, and a retractable mounter. The outer shell of the relay 1 is a polygonal prism-shaped outer shell, the top surface of the polygonal prism-shaped outer shell is smaller than the bottom surface, and the upper part of the side surface inclines inwards. The installer comprises a clamping block 4 and a scissor bracket 3 at the bottom, through holes 8 are formed in two sides of the top surface of the clamping block 4, a first convex clamping groove 6 is formed in the top of the clamping block 4, and a plurality of limiting holes 12 are formed in the side surface of the first convex clamping groove 6, as shown in fig. 3.
