Abstract
The utility model relates to a pressure control structure of a hand saw press handle, particularly a control structure which can change a saw blade quickly. The infrastructure of a hand saw does not change. The utility model is mainly characterized in that the press handle is provided with a long slotted hole through which a screw rod penetrates, and the screw rod can just be screwed with a screw block fixed on the center of a grab handle in the same axle center. One side of the press handle is an open mouth notch, and one end of the notch, which is connected with the screw rod, is upward provided with a projection. When the press handle is pressed to move, the open mouth notch can just cover the press handle to be buckled and closed, and the projection can just press downward the press handle to reach the fixation of the saw blade. Inversely, the press handle is not pressed downward by the projection so that the saw blade is loosened to carry out reloading. The structure causes the saw blade to be reloaded simply and fast, the utility model does not need to obviously increase cost, and can carry out the tension regulation of the saw blade.
Description
The utility model is the control structure that presses that presses handle about handsaw, is to have tool to press a kind of improvement of the handsaw of handle to habit, belongs to hand tools.
Habit has handsaw to be made of saw bow, lever and saw blade etc., on the structure that changes the outfit of saw blade, is at the opposed spiral shell piece that is provided with chimeric saw blade of saw bow body lever, cooperates the butterfly nut spiral shell to move to loosen or to screw tight saw blade, and its shortcoming is that speed is slow, eliminates gradually.At present, the handsaw industry has been produced a kind of utilization and has been pressed the change the outfit handsaw of saw blade of handle, its primary structure is: be connected with pin with saw body pressing handle one end, the other end is established circular hole, pass in the mesopore that circular hole gos deep into lever with a screw rod, the lever mesopore establish one fixedly spiral shell piece and screw rod screw togather, when execution screws togather motion, press handle and promptly compress or loosen, reach the purpose that saw blade changes the outfit.Though this structure makes progress, but still with the spiral shell flowing mode saw blade that changes the outfit, also quick inadequately, pressing handle simultaneously has potential difference when pressing, and screw rod and spiral shell piece are difficult to become concentric to screw togather.
The purpose of this utility model is to overcome the disappearance of above-mentioned prior art and is improved, provide that a kind of both to have kept existing handsaw foundation structure constant, significantly do not increase cost again, move by the pivot of a handle and to realize changing the outfit fast of saw blade, guarantee that simultaneously screw rod and spiral shell piece are the control structure that presses that concentric screws togather.
The purpose of this utility model be achieved in that handsaw saw bow, lever, saw blade, to press foundation structures such as handle and screw rod constant, press handle and be provided with long slot bore, screw rod passes this slotted eye and deeply is fixed in spiral shell piece in the lever mesopore and is concentric and screws togather, the screw rod other end is connected with handle with pin, one side of handle is open short slot, and the end that short slot is connected with screw rod is provided with projection.Pivot moves handle, can make the opening port short slot coat fastening just and press handle, makes projection press down the saw blade that presses on the handle is fixed, or break away from fastening and break away from the saw blade that projection presses down, and realizes changing the outfit fast of saw blade.
Below, the embodiment that provides in conjunction with the accompanying drawings, make describing in further detail to the utility model:
Fig. 1, outside drawing of the present utility model
Fig. 2, element exploded view of the present utility model
Fig. 3, cutaway view of the present utility model
Fig. 4, operation chart of the present utility model
As shown in the figure, the utility model is that tool is pressed the in addition improved handle control structure that presses of handle handsaw, its saw bow (1), lever (2), saw blade (3), presses handle (4) and utilizes screw rod (5) to pass and press handle (4) and just be with the spiral shell piece (7) of lever (2) mesopore and screw togather and make and press handle (4) and be fixed saw blade (3) or loosen replacing saw blade foundation structures such as (3) constant.
As shown in Figure 1, 2, 3, an end of saw bow (1) is provided with projection (11), and chimeric for the saw hole of saw blade (3) one ends, the saw Kong Ze of the other end of saw blade (3) is entrenched on the projection (41) that presses handle (4).An end that presses handle (4) is hubbed on the body of saw bow (1) with pin (6), then presses handle (4) and can strain or loosen saw blade (3) when the other end is pressed.The utility model mainly is to solve to press handle (4) and pressed control structure, and saw blade (3) enables to change the outfit fast.For reaching this purpose, be provided with long slot bore (42) on the handle (4) pressing, screw rod (5) passes this slotted eye (42) and gos deep in the mesopore of lever (2), and just interior spiral shell piece (7) is concentric and screws togather with being fixed on lever (2) mesopore.Press handle (4) when the pressurized movable property is given birth to displacement, long slot bore (42) has for the corresponding mobile gap of screw rod (5) generation, so just can guarantee that screw rod (5) and spiral shell piece (7) are concentric and screw togather operation.The other end of screw rod (5) then uses pin (9) to be connected with handle (8).One side of handle (8) is opening port short slot (81), and is provided with projection (82) handle (8) is connected the short slot of an end with screw rod (5) on.Find out from shown in Figure 4, when handle (8) when being vertical, projection (82) does not press down and presses handle (4), saw blade can change the outfit this moment, when handle (8) presses down when horizontal, its opening port short slot (81) just coats and presses handle (4) and be fastening, and projection (82) then presses down and presses handle (4) and make saw blade (3) fixing.In the time will carrying out tension adjustment to saw blade (3), only need make handle (8) be non-fastening shape, turn handle (8) interlock screw rod (5) is and is screwed into or spiral shell goes out screws togather motion, can adjust the tension force of saw blade (3).
In sum, the utility model is controlled with a handle, make handle be connected and pivoted with pin with screw rod, handle one side is the opening port short slot, and on the short slot of the end that is connected with screw rod, be provided with projection, when pressing handle, projection presses down and presses that handle or disengaging press down and the purpose that reaches the saw blade that changes the outfit fast.Simultaneously, press handle and be long slot bore, and make screw rod place the mesopore of lever, can guarantee screw rod and be fixed in spiral shell piece in the lever mesopore to be concentric and to screw togather for the screw rod place of passing.When handle is non-fastening shape, execute the also adjustable saw bar of handle pressure.In a word, it is constant that the utility model has kept the basic structure of handsaw, significantly do not increase cost, and the effect of the saw blade that changes the outfit is fast arranged, and is a kind of improved suitable control structure that presses.
