Special punching mechanism for handle positioning hole of manual folding saw

Abstract

The invention discloses a special punching mechanism for a handle positioning hole of a manual folding saw. The punching mechanism comprises a fixing bottom plate, a fixing base extending front and back is fixed to the middle of the top face of the fixing bottom plate, a mounting positioning groove extending front and back is formed in the middle of the top face of the fixing base, and a middle supporting plate is fixed to the middle of the bottom face of the mounting positioning groove; a to-be-machined handle body is inserted into the mounting positioning groove in a sleeved mode, and the middle supporting plate is inserted into a bottom face middle groove formed in the middle of the bottom face of the handle body in a sleeved mode; and a supporting frame is fixed to the front portion of the top face of the fixing bottom plate, an upper pressing oil cylinder is fixed to the middle of the top face of a top plate of the supporting frame, a push rod of the upper pressing oil cylinder penetrates through the bottom face of the top plate of the supporting frame and is fixedly provided with a lifting plate, and an upper pressing block is fixed to the bottom face of the lifting plate and abuts against the top face of the handle body. According to the punching mechanism, the handle body can be automatically pressed and fixed, automatic punching is achieved, the effect is good, the efficiency is high, and the punching mechanism is suitable for batch production and machining.

Description

Technical field[0001]The present invention relates to the field of manufacture and manufacturing of garden agricultural tools, and more particularly to a handle mechanism for manual folding saw holes.Background technique[0002]The manual small lumators used in existing gardens or agriculture are generally fixed to the handle and the steel saw blade, which cannot be folded, so that the space takes up, it is inconvenient to carry; therefore, some manual small lumators are folded. To make it easy to carry, however, since the handle and the steel saw blade are active connection, the steel saw blade is used when the user uses the case, and the steel saw blade is easily folded back, but makes the handle The hand is injured, so it is necessary to set it after the steel saw blade is turned out, which can be fixed, which can set the slider on the handle, extend into the top surface of the steel saw blade through the card seat on the slider. In the arranged card, and the slider is slid on the ...

Problems solved by technology

[0002] The existing manual small-scale logging saws used in gardening or agriculture are generally fixedly connected with the handle and the steel saw blade, which cannot be folded, which makes it take up a lot of space and is inconvenient to carry; therefore, some existing manual small-scale logging saws are folded. However, when in use, since the handle and the hacksaw blade are movably connected, when the hacksaw blade is in use, when the user uses it improperly, it is easy to fold the hacksaw blade back to the position, so that the grip of the handle The hand is injured, so it is necessary to set up a hacksaw blade that can be fixed after it is turned out. It can be provided with a slider on the handle, and can be inserted into the top surface of the hacksaw blade through the clamping part on the slider. When the slider slides on the handle part, it is necessary to set positioning holes on the left and right sides of the handle part to install the positioning mechanism to ensure that the positioning part of the installation positioning mechanism can be locked when the slider slides in place. Place it in the concave hole on the slider to achieve fixation, but the existing processing method is to manually punch holes on the left and right sides of the handle to make positioning holes, which requires a lot of manual labor, and the effect is poor and the efficiency is low
