Abstract
A telescopic saw which can be fed for multiple models to incorporate is an improvement of the existing woodworking hand saw. The hand saw of the device is composed of two large divisions: an upper connecting rod and a down-slide rod. The middle of the hand saw is equipped with a position buckle which effects positioning and locking functions for the length of saw blades with multiple models, and therewith, a uniqueness that the existing hand saw only can provide saw blades with a model is solved. A saw body is also provided with a hexagonal clamping rod, and freely adjusting the tooth surface of the saw blade in six directions of 360 degrees can be satisfied to be convenient of varieties when sawing the boards. More than that a centre support rod of the existing woodworking hand saw is removed, and in this way, the area of sawing the board can be increased by a time. This structure can be randomly torn down and quite convenient to carry with small space occupancy rate and labor saving; the design has simple structure, original external appearance and high practicability, and is convenient of implementing.
Description
Technical field
The utility model is to improve back a kind of flexible saw of using with for multiple model saw blade that has on existing Woodworking hand saw, and it relates to the overall structure of Woodworking hand saw.
Background technology
Well-known existing Woodworking hand saw has centre post, is tightened saw blade with rope then, and its structure is single, and the area when sawing a board is also because there be corresponding diminishing of stopping of centre post.Moreover such handsaw can only provide a kind of model saw blade to use, can not use with in conjunction with multiple model saw blade, especially can not use in conjunction with hacksaw blade, because can not effectively dismantle to it, so often various model handsaws are a lot of when carrying, it is very big to take up space, and requires great effort very much again, also very inconvenient.
Summary of the invention
Skill problem to be solved in the utility model all provides a kind of confession flexible saw that multiple model saw blade is used with overcoming defective of the prior art.
Goal of the invention of the present utility model is finished by the following technical programs.
A kind of flexible saw that supplies multiple model saw blade to use with is characterized in that:
Described flexible saw is made up of upper connecting rod and drop shot two large divisions.
The described upper connecting rod shape that meets at right angles, its preceding inside pipe wall is positive hole, and the aperture is the poor tooth of outer angle, links to each other with interior angle setscrew nut, and the rear end is to be with the sponge sheath on the arc angling Square handle, and has in the interior hexagonal circular hole and link to each other with outer-hexagonal cylinder clamping bar.
The described drop shot shape that meets at right angles, its front portion is positive square bar, the rear end is to have cut gap on the square staight shank of chamfering, and has an inner hexagonal hole and link to each other with outer-hexagonal screw thread clamping bar, again with tighten nut and sting mutually.
Described drop shot inserts anterior positive square bar in the square hole of upper connecting rod, adjust Len req after, added by interior angle setscrew nut and to be tightly locked.
Outer-hexagonal cylinder clamping bar in the described upper connecting rod passes circular hole in the interior hexagonal on the sponge sheath arc angling Square handle, adjusts required angle and injects the saw blade upper end, clamps locking by trip bolt.
Outer-hexagonal screw thread clamping bar in the described drop shot, inject the saw blade lower end after, clamp locking by trip bolt, and then correspondence adjusts required angle, penetrate in the inner hexagonal hole and in gap, tighten saw blade by tightening nut.
Compared with prior art, the utility model gets on except its centre post at existing Woodworking hand saw, make its area that saws a board increase by one times, and be provided with the locker that can carry out scalable slippage for the length of multiple model saw blade, also be provided with for the saw blade flank of tooth and carry out six direction regulatory function in 360 °, improve the diversity when sawing a board, and easy accessibility, it is little to carry the time space occupation rate, and operation is also convenient, laborsaving.The design is simple in structure, and the outward appearance novelty is practical, is convenient to implement.

The specific embodiment
Shown in Fig. 1～3, this flexible saw is to the existing integrally-built improvement of Woodworking hand saw, and then a kind of flexible saw that can provide multiple model saw blade to use with, requires:
Described flexible saw is made up of upper connecting rod (1) and drop shot (2) two large divisions, form right angle states all, and the preceding inside pipe wall of its upper connecting rod (1) is square hole (12), and the aperture is outer angle tooth (4) shape that is pickled with grains or in wine, and stings (see figure 3) mutually with interior angle setscrew nut (3).
Described drop shot (2) front portion is positive square bar (14), require its four limits size and the length all should be less than square hole (12) four limit sizes and the degree of depth (see figure 3) in the preceding inside pipe wall of upper connecting rod (1), and be inserted in the square hole (12), after adjusting saw blade (15) length that needs to use, screw by interior angle setscrew nut (3), force the outer angle tooth (4) that is pickled with grains or in wine tightly to bite positive square bar (14) and give position and lock (seeing Fig. 1-2).
Outer-hexagonal cylinder clamping bar (5) in the described upper connecting rod (1) passes out circular hole (6) in the interior hexagonal of the arc angling Square handle end that is with sponge sheath (11), adjust the required angle of saw blade (15) flank of tooth, inject saw blade (15) upper end and twisted outer-hexagonal cylinder clamping bar (5) clamping saw blade (15) upper end (seeing Fig. 1-2) by trip bolt (10).
After outer-hexagonal screw thread clamping bar (7) in the described drop shot (2) inserts saw blade (15) lower end, twisted outer-hexagonal screw thread clamping bar (7) clamping saw blade (15) lower end by trip bolt (10), corresponding then upper end angle is passed inner hexagonal hole (8) lining accordingly and is screwed outer-hexagonal screw thread clamping bar (5) and then tighten saw blade (15) itself (seeing Fig. 1-2) in gap (13) by tightening nut (9).
