Adjustment structure of garden shears

Abstract

An adjustment structure of garden shears, which utilizes an aligning lever disposed on the outer surface of an outer tube to support a protruding block; because the protruding block can be fitted into a trough on the outer surface of the inner tube and become secured, the inner tube and the outer tube become fastened together as a result. Moreover, a marked unit is disposed where said inner tube and outer tube are joined, thereby allowing the invention to have a structurally simple handle that can be aligned effectively, which in turn allows users to grasp the precision in the movement between said inner tube and outer tube.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

FIGS. 1 to 6 illustrate the selected embodiments of this invention; the embodiments only serve the purpose of elucidation and are not to be used to limit the scope of the invention in any ways.

The adjustment structure of garden shears of this embodiment, as shown in FIG. 1 and FIG. 2, comprising:

a first blade 1 and a second blade 2 being crossly joined together, said first and second blades 1 and 2 are crossly joined by the use of a removable rotating button 3; in this embodiment, since said first blade 1 and second blade 2 both connect to an identical adjustment structure 4, only one adjustment structure 4 is required as an example for the purpose of further explanation, said adjustment structure 4 comprising:

an outer tube 41, one end of said outer tube 41 being disposed with a grab handle 411.

an inner tube 42 being fitted into said outer tube 41, a trough 421 being disposed on the outer surface of said inner tube 42, the inner surface of said trough 421 has a plurality of grooves 422, and a cavity 423 is formed in said trough 421 where it corresponds to and holds a stopper 43.

an aligning member 44 being located at where said outer tube 41 and inner tube 42 are joined, said aligning member 44 has a through hole 441 for a protruding section 451 of a protruding block 45 to fit through; in this embodiment, the protruding section 451 of said protruding block 45 has a secondary grooved section 452 for allowing it to become more fastened with the grooves 422 on the inner surface of said trough 421; said through hole 441 has a lug 442 on both lateral sides, respectively, each lug 442 corresponds to one another and has respective through opening 443.

an aligning board 46 being joined with said aligning member 44 by the use of a pin 47 being fitted through each of said through opening 443 in each said lug 442; in this embodiment, said aligning board 46 comprises a pressing portion 461 and a curved portion 462, said curved portion 462 becomes supportive of said protruding block 45 when said pressing portion 461 is pressed downwards.

a marked unit 48 being disposed on the two lateral sides of said trough 421 on the outer surface of said inner tube 42, said marked unit 48 is consisted of a surface 412 of said outer tube 41 that faces away from one end of said grab handle 411, and a marked line 481 corresponding to said surface 412 and located at the two lateral sides of said trough 421 on the outer surface of said inner tube 42, for allowing precise movement between said inner tube 42 and outer tube 41.

The use of the adjustment structure of garden shears in this invention is further explained with the aid of relevant figures below:

Referring to FIG. 3, when the length of outer tube 41 is to be adjusted, the pressing portion 461 of the aligning board 46 should be pushed upwards at first, so that the curved portion 462 no longer supports the protruding block 45 of aligning member 44, and protruding block 45 becomes loosened and no longer fastened with the trough 421 of inner tube 42; subsequently, the outer tube 41 can be adjusted along the outer surface of the inner tube 42, and users can judge the precision in the movement between the outer tube 41 and the inner tube 42 by observing whether the surface 412 of outer tube 41 is aligned to marked line 481 on the outer surface of inner tube 42 or not. In other words, when the surface 412 of outer tube 41 is aligned to marked line 481 on the outer surface of inner tube 42, it means the inner and outer tubes 42 and 41 are moved horizontally, as shown in FIG. 4; in contrast, if the surface 412 of outer tube 41 cannot be aligned to marked line 481 on the outer surface of inner tube 42, it means the inner tube 42 and the outer tube 41 are slanted. As a result, the invention allows users to clearly grasp the precision in the movement between the inner tube 42 and the outer tube 41.

Subsequently, when the outer tube 41 is adjusted to adequate length, users can press the pressing portion 461 downwards to make the curved portion 462 support said protruding block 45 after the application of force, and then the protruding block 45 will become fastened together with trough 421 of the inner tube 42, as indicated in FIG. 5.

Because protruding block 45 can be fastened into trough 421 on the outer surface of inner tube 42, thereby allowing the inner tube 42 and the outer tube 41 to be secured, thus the invention is not only structurally simple, but also effective for aligning the handles.

Furthermore, because a stopper 43 is disposed in a cavity 423 on the outer surface of said inner tube 42 in this invention, thereby allowing an adjustable distance of adequate length to be placed between the inner tube 42 and the outer tube 41, thus said stopper 43 can stop the protruding block 45 when users are adjusting the length between the inner tube 42 and the outer tube 41, so that the inner tube 42 and the outer tube 41 will not become separated, as indicated in FIG. 6.
