Problems solved by technology
The hand saw can not solve the random change of sawing angle, which affects the function of the hand saw
For small hand saws, it is necessary to replace the saw blade and saw frame immediately, and it can be equipped with other combined tool components that can be used in conjunction. These functions and functions cannot be realized by the structure of the hand saw

The invention discloses a push-loading and dismounting hand saw, which includes a forward bend and a handle. The rear end of an adjustment rod running through the lower chamber is threadedly connected with an adjustment nut. The upper chamber of the handle has a through hole for the handle. The head has a circular notch; the through hole of the handle and the circular notch are relatively matched and can pass through the screw and nut connected by the thread, and the threaded part of the screw is covered with a compression spring; The screw is extruded at the position of the handle groove; the notch of the circular notch is smaller than the inner diameter of the circular notch, and can slide with the threaded part of the screw; the nut has a nut cavity, and the outer diameter of the nut cavity can be matched with the circular notch. The notch is movable fit and larger than the notch of the circular notch; the depth of the handle groove mouth is equivalent to the length of the nut cavity; the inner diameter of the circular notch is the same as the inner diameter of the through hole of the handle; the length of the screw thread is equal to the length of the through hole of the handle The length of the hole; the lower front end of the front bend has a notch with an opening forward, and the notch is embedded with a glass roller knife that is pinned and connected between the walls of the groove. The utility model has the advantages of simple and exquisite structure, convenience and quickness.
Description
technical field [0001] The invention relates to a hand saw, in particular to a push-loading and dismounting hand saw. Background technique [0002] The hand saw is a hand tool that is commonly used in mechanical repairs and assembly when sawing materials. It takes a long time for the traditional hand saw to install the saw blade, which is inconvenient, and it can only be sawed in a single way; the disadvantage is that there is a screw and a nut at one end of the hand saw, which play the role of tensioning and loosening the saw blade, that is, When the saw blade is not sharp or broken and needs to be replaced, it is necessary to loosen the nut, remove the saw blade from the hand saw, install a new saw blade, and then tighten the nut; Time-consuming, and the use of nuts is small in shape, frequent operation, and easy to cause operator fatigue; second, when it is necessary to adjust the sawing angle, the nut must be removed before adjustment, and the angle only has two angles ...
