The first adapter block 202 and the second adapter block 208 are connected by a driving rod 6. There are two length adjustment components 2. Preferably, the driving rod 6 is only installed on the length adjustment component 2 on one side, and a light shaft is passed through between the first adapter block 202 and the second adapter block on the length adjustment component 2 on the other side. With this structure, by rotating the driving rod 6, the distance between the first adapter block 202 and the second adapter block 208 can be changed, and then the inclination angle of the push plate 201 can be changed, and finally the distance between the two insulating plates 1 on both sides can be changed to meet the length requirements of the insulating tools, with convenient adjustment and good use effect.

[0030] In a preferred solution, the two push plates 201 on the same side are connected to the insulating plate 1 through an adapter seat 4.
