Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.

It is noted that when a component/feature is referred to as being "disposed on" another component/feature, it can be disposed directly on the other component/feature or intervening components/features may also be present. When a component/feature is referred to as being "connected/coupled" to another component/feature, it may be directly connected/coupled to the other component/feature or intervening components/features may also be present. The term "connected/coupled" as used herein may include electrical and/or mechanical physical connections/couplings. The term "comprises/comprising" when used herein means the presence of a feature, step or component/part, but does not exclude the presence or addition of one or more other features, steps or components/parts. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

Referring to fig. 1 to 3, an expansion laminate support includes a support seat 1, a limiting step 2 for preventing the laminate from being installed too deeply or not in place is provided at the bottom of the support seat 1, clamping portions 3 are provided at two sides of the upper portion of the support seat 1, one end of each clamping portion 3 is inclined outwards and extends downwards to a position close to the limiting step 2, an expansion portion 4 capable of expanding outwards is further provided at the upper portion of the support seat 1, an expansion hole 5 communicated with the expansion portion 4 is provided at a position corresponding to the expansion portion 4 on the support seat 1, and screws are used to extend into the expansion portion 4 through the expansion hole 5 during installation, so that the expansion portion 4 can expand outwards.

The clamping part 3 is provided with two symmetrically arranged clamping blocks 31 with inclined planes, one end of each clamping block 31 extends towards the limiting step 2, and the extending end has elasticity. When the plywood is installed, the hole site of installation can be reserved on the plywood, and the upper end of chucking portion 3 is less than the lower extreme, so when the installation, the plywood is more down just more firm, in order to avoid the plywood to install not in place, consequently the extension end design of chucking piece 31 possesses elasticity, can guarantee that the plywood is installed firmly, can not install not in place because of chucking portion 3 lower extreme is too big again.

The anti-slip teeth 32 for increasing friction force are arranged on the surface of the clamping block 31, so that the connection firmness between the laminate and the clamping block 31 can be increased when the laminates are contacted.
