Description

Technical Field

[0001] The utility model relates to a pruning device, in particular to a fruit tree branch pruning device. Background Technique

[0002] At present, a Chinese patent with the publication number of CN219087869U discloses a branch pruning device, which includes a first knife handle and a second knife handle that are rotatably connected. Blade plates are arranged at the opposite positions of the first knife handle and the second knife handle, and replacement mechanisms are arranged between the blade plates and the first knife handle and the second knife handle respectively.

[0003] Handles are arranged at the lower ends of the first knife handle and the second knife handle. The handle includes a first rod body and a second rod body that are rotatably connected. A folding mechanism is arranged between the first rod body and the second rod body. The folding mechanism includes a connecting plate fixedly connected to the surface of the first rod body, and the connecting plate is fixedly connected to the second rod body through a second bolt. Through the designed folding mechanism, it is convenient to fold the handle on the scissors when not in use, reduce the length of the scissors, facilitate carrying, and reduce the space occupied by the scissors during the carrying process.

[0004] However, during the use of the above-mentioned branch pruning device, the total length of the handle is fixed, it is difficult to prune the branches at higher positions, and there is a defect of low applicability. Summary of the Utility Model

[0005] In view of this, the purpose of the utility model is to provide a fruit tree branch pruning device, which can be used to prune the branches at higher positions and has the advantage of high applicability.

[0006] To solve the above technical problems, the technical solution of the utility model is: a fruit tree branch pruning device, including two groups of pruning units arranged alternately, and the two groups of pruning units are rotatably connected through a pruning shaft. The pruning unit includes a pruning knife and a holding handle integrally formed. The holding handle includes a connecting rod, a storage box and a holding handle connected in sequence. An extension rod is arranged in the storage box. An extension column is arranged at the upper end of the extension rod. A connecting hole for threaded connection with the extension column is opened at the lower end of the extension rod. An extension hole for threaded connection with the extension column is opened at the lower end of the holding handle.

[0007] Through the above technical solution, when the pruning device needs to be used to prune branches at higher places, the corresponding number of extension rods are taken out from the storage box according to the height of the branches, and the extension rods are connected in sequence through the cooperation of the extension column and the connection hole, and then the extension column of the upper extension rod is threaded into the extension hole to connect the extension rod to the gripping handle to increase the length of the pruning device. By installing different numbers of extension rods, branches of different heights can be pruned, so that the pruning device has the advantage of high applicability. The extension rods are stored in the storage box, making it more convenient to carry the pruning device.

[0008] Preferably, the storage box comprises a box body and a box cover, an access opening is provided on a side wall of the box body, the box cover is detachably connected to the access opening, and the extension rod is placed in the box body.

[0009] Through the above technical solution, the extension rod can be taken out and placed when the control box cover leaves the access opening, and the extension rod can be restricted when the control box cover enters the access opening to prevent the extension rod from escaping from the storage box.

[0010] Preferably, a fixing bracket is provided in the box body, a clamping opening is provided on a side wall of the fixing bracket, and the extension rod is clamped in the clamping opening.

[0011] Through the above technical solution, the fixed bracket with the clamping opening can limit the extension rod, so that the extension rods can be stacked more neatly, and the extension rods can be taken more conveniently.

[0012] Preferably, a protective cushion is provided at the inner wall of the clamping opening, and the protective cushion presses against the outer wall of the extension rod.

[0013] Through the above technical solution, the protective cushion can be used to protect the extension rod, so that the extension rod is not prone to wear or even deformation.

[0014] Preferably, a guide slot is provided on the inner wall of the box body, and the guide slot extends along the depth direction of the access opening. A guide slider is provided on the side wall of the fixed bracket, and the guide slider is slidably connected in the guide slot.

[0015] Through the above technical solution, the guide groove and the guide slider cooperate with each other to limit and guide the sliding of the fixed bracket, making the storage process of the extension rod more convenient.

[0016] Preferably, a first threaded hole is formed at the lower end of the connecting rod, a first threaded post is arranged at the upper end of the box body, and the first threaded post is threadedly connected in the first threaded hole. A second threaded hole is formed at the lower end of the storage box, a second threaded post is arranged at the upper end of the holding handle, and the second threaded post is threadedly connected in the second threaded hole.

[0017] Through the above technical solution, the cooperation of the first threaded hole and the first threaded post makes the disassembly and assembly of the storage box more convenient. The cooperation of the second threaded hole and the second threaded post makes the disassembly and assembly of the holding handle more convenient.

[0018] Preferably, the holding handle further includes a plug, and the upper end of the plug is threadedly connected in the extension hole.

[0019] Through the above technical solution, the plug can block the extension hole, making it difficult for dust and impurities to enter.

[0020] Preferably, a receiving groove is formed at the lower end of the plug, and an operating handle is hinged in the receiving groove. When the operating handle is received inside the receiving groove, the outer wall of the operating handle abuts against the inner wall of the receiving groove.

[0021] Through the above technical solution, when the plug needs to be rotated, the operating handle is rotated so that the operating handle protrudes from the receiving groove. Then, the user can hold the operating handle by hand and control the rotation of the plug, making the rotation process of the plug more convenient and labor-saving. BRIEF DESCRIPTION OF THE DRAWINGS
