Description

Technical Field

[0001] This utility model belongs to the field of garden tool technology, specifically relating to a long-handled pruning shear. Background Technology

[0002] The pruning shears currently used consist of a blade and a support rod. The blade is fixedly connected to the support rod, with one support rod corresponding to one blade. The shearing operation is performed by operating the handle. For example, the pruning shear with publication number CN201360445Y not only has the function of pruning but also has the function of replacing the blade head. However, it does not have the function of increasing the length and cannot be used for trees of different heights. Therefore, an extended pruning shear is designed. Utility Model Content

[0005] Preferably, a guide slot is provided on the lower section of the handle, and an insert plate is provided on the extension rod, the insert plate being connected to the guide slot.

[0006] Preferably, a lock hole is provided on the lower section of the handle, a lock plate is provided inside the extension rod, and a lock head and a push pin are provided on the lock plate, with the lock head engaging in the lock hole.

[0007] Preferably, a spring is provided between the locking plates.

[0008] Preferably, a positioning rod is provided inside the spring, and the two ends of the positioning rod are connected to the inner wall of the extension rod.

[0009] Preferably, a collar is provided at one end of the main connecting rod, and one end of the secondary connecting rod is connected inside the collar.

[0010] Preferably, a pin is inserted into the collar.

[0011] Preferably, the extension rod is provided with a pin mounting hole.

[0012] The technical effects and advantages of this utility model are as follows: 1. Through the modular extension rod design, users can easily assemble pruning shears of different lengths according to the actual pruning height or distance requirements, easily cope with the pruning of branches at high places and far away, and improve work efficiency and safety.

[0013] The guide slot and insert plate work together, and the locking mechanism consisting of a locking plate, lock head, spring and push post enables quick connection and quick separation between the extension rod and the handle section, which is very convenient.

[0014] The main and auxiliary connecting rods are connected by a collar and a pin, ensuring that the operating force can be stably and synchronously transmitted from the movable handle to the scissors in the extended state. Attached Figure Description

[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0021] This utility model provides, for example Figures 1-4 The long-handled pruning shears shown include an upper handle section 1 and a lower handle section 2. An extension rod 3 is detachably installed between the upper handle section 1 and the lower handle section 2. A fixed handle 4 and a movable handle 5 are installed at one end of the lower handle section 2. Scissors 6 are installed at one end of the upper handle section 1. The scissors 6 are connected to the movable handle 5 through a main connecting rod 7 and a secondary connecting rod 8. The secondary connecting rod 8 is installed inside the extension rod 3. The main connecting rod 7 is installed inside both the upper handle section 1 and the lower handle section 2.

[0022] Specifically, the lower section 2 of the handle and the extension rod 3 are connected by the following structure: a guide slot 9 is provided on the lower section 2 of the handle, and an insert plate 10 is provided on the extension rod 3, with the insert plate 10 connected to the guide slot 9; a lock hole 18 is provided on the lower section 2 of the handle, and a lock plate 11 is provided inside the extension rod 3, with a lock head 12 and a push pin 13 on the lock plate 11, the lock head 12 being engaged in the lock hole 18; a spring 14 is provided between the lock plates 11; a positioning rod is provided inside the spring 14, with both ends of the positioning rod connected to the inner wall of the extension rod 3; pressing the push pin 13 moves the lock plate 11 inward, moving the lock head 12 inward together, and then inserting it. Under the push of the spring 14, the lock plate 11 returns to its original position outward, and the lock head 12 is engaged in the lock hole 18, thus achieving the connection.

[0023] Specifically, when adding the extension rod 3, the main connecting rod 7 also needs to be lengthened. Therefore, a secondary connecting rod 8 is set up. The secondary connecting rod 8 is connected to the main connecting rod 7 to achieve normal shearing control of the extended shear 6. The structure is as follows: a collar 15 is set at one end of the main connecting rod 7, and one end of the secondary connecting rod 8 is connected to the collar 15. A pin 16 is inserted into the collar 15. A pin mounting hole 17 is set on the extension rod 3. The secondary connecting rod 8 is inserted into the collar 15, and the pin 16 is inserted into the collar 15 from the pin mounting hole 17 to achieve the connection between the collar 15 and the secondary connecting rod 8.

[0024] It should be noted that the above structure illustrates the connection between the lower section 2 of the handle and one end of the extension rod 3, as well as the connection between the corresponding secondary connecting rod 8 and the main connecting rod 7. Similarly, the other end of the extension rod 3 is connected to the upper section 1 of the handle in the same way, and the inner side also has the connection between the secondary connecting rod 8 and the main connecting rod 7, which will not be elaborated here. Moreover, multiple extension rods 3 can also be connected to each other to increase the length. The upper section 1 of the handle and the lower section 2 of the handle can also be directly connected to form the shortest length pruning shear after combination, which is flexible in use.

[0025] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
