Abstract

The invention discloses a bottom plate assembly for a handheld sander. The bottom plate assembly comprises a bottom plate and a bottom plate pad which are arranged vertically. Two oppositely-arranged sand paper clamp assemblies are arranged on the upper portion of the bottom plate. Each sand paper clamp assembly comprises a sand paper clamp and a sand paper clamp wrench. Each sand paper clamp wrench is arranged below the corresponding sand paper clamp. Each sand paper clamp wrench is an integrally-formed rigid body. Each sand paper clamp wrench is provided with a downwards-inclining pressing part and an upwards-cocked open wrench part. Each sand paper clamp is provided with a clamping part and a fixed part. The fixed parts of the sand paper clamps are fixed. When the open wrench parts of the sand paper clamp wrenches are pressed downwards, the pressing parts of the sand paper clamp wrenches are lifted up, meanwhile, the clamping parts of the sand paper clamps are driven to be cocked upwards, no force is applied to the sand paper clamp wrenches, and the clamping parts of the sand paper clamps keep in a state of clamping sand paper. The bottom plate assembly is simple in structure, the sand paper is mounted and demounted conveniently and fast, and manufacturing cost is low.

Description

technical field [0001] The invention relates to a part for grinding and polishing tools, in particular to a bottom plate assembly for a hand-held sander. Background technique [0002] When grinding or polishing workpieces, sanding devices such as sanders are often used, especially hand-held sanders, which are welcomed by users because of their convenience and flexibility. The sander is located in the casing and is used to provide the driving device for driving force. The driving device is connected with the working base plate through the transmission device, and abrasive materials such as sandpaper are attached to the bottom surface of the base plate. When working, the driving device generally drives the bottom plate assembly to move eccentrically, and the sandpaper attached to the bottom plate assembly will move accordingly to polish the working surface so as to make it smooth and even. The structure of the bottom plate of the existing sanding machine is complicated, and i...
