Problems solved by technology

Although this device can solve the disadvantages of drilling holes for lengthening the handle in the past, the connection of the device is not fast enough, and it often falls off during use, and the arc groove of the device is relatively troublesome in processing. break, and the whole device is useless.
In addition, this device does not solve the problem of the limited use of the previous connecting device, and another device needs to be processed for different rods to be connected

Abstract

The invention discloses a connecting device for lengthening a handle. The connecting device comprises a fixing sleeve and two connecting sleeves, the fixing sleeve is a hollow cylinder, a retaining plate is respectively arranged at two axial ends of the fixing sleeve, a fixing hole is arranged on each retaining plate, the connecting sleeves are cylinder, and the connecting sleeves can be inserted in the fixing holes of the fixing sleeve. Taper holes are axially arranged at one ends of the connecting sleeves to be used for fixing a rod to be connected, and two rectangular grooves are radially arranged at the other ends of the connecting sleeves and respectively arranged on two sides of the connecting sleeves. Snap joint blocks are arranged in the rectangular grooves, the snap joint blocks are fixed in the rectangular grooves through springs at the bottom, buttons are arranged on one sides of the snap joint blocks close to taper holes, ladder-shaped clamping blocks are arranged on the other sides of the snap joint blocks, and the snap joint blocks, the buttons and the ladder-shaped clamping blocks are integrated. The ladder-shaped clamping blocks can clamp the retaining plates on the fixing sleeve, slope angles of the ladder-shaped clamping blocks are 20 degrees or 30 degrees. The connecting device can be applicable to handles and rods to be connected in various types and sizes, and is simple in structure, convenient to manufacture and strong in applicability.

Description

technical field [0001] The invention relates to a connecting device, in particular to a connecting device used to lengthen a handle, and belongs to the technical field of connecting devices. Background technique [0002] In the current industrial production and life, in order to facilitate the operation in various environments, it is often necessary to extend the handle. In the past, when the handle was lengthened, bolts, pins, etc. were used to connect and fix it. But this kind of connection not only needs to drill equal-sized holes on the handle to be connected, but also can only be one size for the handle to be connected, which is both troublesome and very limited in use. For this reason, Chinese Patent No. ZL201020633674.2 is a connecting device for lengthening the handle. The disclosed connecting device includes a hollow tubular handle, an arc-shaped plate and an arched cover. The cam end is against the curved plate to realize the elongation of the handle. Although t...
