Description

Gardening tool telescopic rod

The present invention relates to a "gardening tool telescopic rod", and more particularly to a gardening tool rod that can be telescoped and can prevent relative rotation between the tubes.

According to the conventional gardening tool (90) (as shown in the eighth figure), an extension rod (91) is often provided, and one end of the extension rod (91) is provided with an openable cutting edge (92), and The cutting edge (92) is inserted into the extension rod (91) by a control cable (93), and is connected to a handle (94) at the other end of the extension rod (91). The handle (94) provides a push to open and close the cutting edge (92) via the control cable (93), allowing the user to cut the lobe at a high position on the ground.

However, the conventional structure as described above still has the following problems in practical applications: (1) the extension rod (91) itself cannot be telescopically mobilized in length according to actual use requirements, so it is used and carried. The upper system is quite inconvenient, and the storage also has a problem of occupying space; (2) the conventional set of the extension rod (91) and the grip (94) cannot block the extension rod (91) from idling on the grip (94). When the extension rod (91) rotates, it may be improper to pull the control cable (93) worn in the extension rod (91), and excessive pulling will cause the control cable (93) to fail to operate normally.

Therefore, the inventor of this inventor is in light of this, and the idea of thinking and creation is designed with many years of experience. After many discussions and trials of sample tests, and many revisions and improvements, it is launched. Bright.

The extension rod of the conventional gardening tool cannot be telescopically moved, nor can it restrict the extension rod from idling on the grip. This is a technical problem to be solved.

The garden tool telescopic rod of the present invention comprises an outer tube, a middle tube and an inner tube which are sequentially arranged from the outside to the inside, and a first pressing unit is coupled between the outer tube and the middle tube. A second pressing unit is coupled between the middle tube and the inner tube, and the installation of the first pressing unit and the second pressing unit can stop the outer tube, the middle tube and the inner tube from being opposite to each other at a lower limit of a normal state. Rotating, when the outer tube, the middle tube and the inner tube complete the telescopic movement, the middle tube and the inner tube can be tightened by the operation of the first pressing unit and the second pressing unit. Positioning, wherein the outer tube has a first end and a second end, and the outer circumference is recessed with at least one card slot extending from the first end toward the second end, the middle tube has a a first end and a second end, the outer circumference is recessed with at least one card slot extending from the first end toward the second end, the inner tube has a first end and a second end, and the outer circumference At least one card slot extending from the first end toward the second end, the first pressing unit having a sleeve connected thereto A bundle ring, the inner tube portion and the inner portion of the sleeve of the cinch ring with respect to the outer tube and the slot line in the tube is provided with at least a first sub-card and at least one second rib a rib, a notch is formed on one side of the collar, and an extension block is protruded from the two ends formed by the notch, and the two extension blocks are provided with an eccentric handle through a bolt pivoting group. The second pressing unit has a sleeve and a bundle of rings connected, and the inner tube portion of the sleeve and the inner ring portion of the collar are respectively provided with respect to the card slot of the middle tube and the inner tube. a first rib and at least one second rib, a notch is formed on one side of the collar, and an extension block is protruded from the two ends formed by the notch, and the two extension blocks are passed through a bolt The pivot group has an eccentric handle; thereby, it can constitute the gardening tool telescopic rod.

(1) The telescopic rod of the gardening tool of the present invention can realize the telescopic movement of the length of the gardening tool rod according to the actual use requirement, which is convenient to use and carry, and has the advantage of less occupying space in storage.

(2) The garden tool telescopic rod of the present invention, which utilizes a second rib of the first pressing unit to engage with the middle tube card slot, a second rib of the second pressing unit, and the The fit of the inner tube card slot enables the middle tube and the inner tube to be locked, so that no relative rotation can be generated between the tubes, and the system can prevent the gardening tool from using the control wire. The improper rotation between the outer tube, the middle tube and the inner tube is excessively pulled, so that the control wire can be normally actuated.
