Embodiment Construction

[0008] Specific embodiments of the present invention will be further described in detail below.

[0009] like figure 1 As shown, a quick clamping wrench of the present invention includes a handle 10 , and a clamping portion 12 is provided at the front end of the handle 10 . The clamping portion 12 is circular and has a fracture 14 in the middle. An outwardly protruding ear portion 16 is provided at the fracture 14 of the clamping portion 12 , and a through connection hole (not shown) is provided on the ear portion 16 . A pin 18 passes through the connection hole and connects the fracture 14 of the clamping part 12, and the front part of the pin 18 is pivotally connected with a comma-shaped eccentric clamping member 20.

[0010] When the quick-clamping wrench of the present invention is in use, the eccentric clamping member 20 is rotated counterclockwise, so that the radius of the clamping member 20 close to the ear 16 increases, thereby tightening the fracture 14 . On the c...

Abstract

The invention discloses a wrench capable of clamping fast. The wrench capable of clamping fast includes a handle, an annular clamping part, an plug part and a through connecting hole, wherein the annular clamping part is installed at the front end of the handle and a fracture is formed in the clamping part, the plug part is installed on the fracture of the clamping part and protrudes outwards, and the through connecting hole is formed in the plug part. The wrench capable of clamping fast is characterized in that the wrench further includes a pin penetrating through the connecting hole, and an eccentric clamping unit is in pivot connection with the front portion of the pin. According to the wrench capable of clamping fast, the fracture is enabled to clamp or loose an object fast with one motion through the comma-shaped eccentric clamping unit. The wrench capable of clamping fast has the advantages of simple structure, convenient operation and the like.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to a wrench. Background technique [0002] Angle grinder is a common electric tool, which can be widely used in cutting, grinding, polishing and other operations. The grinding wheel of the angle grinder needs to be replaced frequently due to wear. When replacing the grinding wheel, a round wrench is usually used to remove and tighten the fixing nut of the grinding wheel. This type of wrench generally includes a handle, and in front of the handle is an annular clamping portion. There is a fracture on the clamping part to increase the inner diameter of the clamping part so that it can be smoothly sleeved on the fixing nut. There is an outwardly protruding ear at the fracture, and there is a through hole on the ear, and then a bolt is used to pass through the hole. The holding part is tightly fixed on the fixing nut for disassembly or tightening operation. It usual...
