DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-8 This application is described in further detail.

[0036] The present application embodiment discloses a pruning shears blade set. Figure 1 and Figure 2 A pruning shears blade set includes a blade assembly 1, a serration assembly 2 and a blade assembly 3. The serration assembly 2 is movably arranged on the blade assembly 1, so that the blade assembly 1 can prune harder branches through the serration assembly 2, and the blade assembly 3 shields and protects the serration assembly 2.

[0037] Reference Figure 1 The blade assembly 1 includes a first blade 11 and a second blade 12, and the first blade 11 and the second blade 12 are abutted against each other. The end of the first blade 11 abutting against the second blade 12 is the lower end of the first blade 11, and the end of the second blade 12 abutting against the first blade 11 is the upper end of the second blade 12. The first blade 11 and the second blade 12 are cross-axially connected, thereby realizing the bite of the first blade 11 and the second blade 12.

[0038] Reference Figure 1 and Figure 2 Since the structures of the first blade 11 and the second blade 12 connected to the sawtooth assembly 2 are consistent, in this embodiment, the structure of the first blade 11 connected to the sawtooth assembly 2 is described as an example.

[0039] Reference Figure 1 , Figure 2 and Figure 3 A mounting groove 111 is provided at the end of the first blade 11 close to the engagement with the second blade 12, and the sawtooth assembly 2 is arranged in the mounting groove 111. Openings 112 are provided at the lower and upper ends of the first blade 11 and the second blade 12, and the openings 112 are communicated with the mounting groove 111.

[0040] Reference Figure 2 and Figure 4 The sawtooth assembly 2 includes a sawtooth body 21, a connecting plate 22 and a clamping column 23. The connecting plate 22 is divided into two parts, the lower part of the connecting plate 22 and the sawtooth body 21 are integrally formed, and the upper part of the connecting plate 22 protrudes from the sawtooth body 21. When the sawtooth body 21 is located in the mounting groove 111, the upper end of the upper part of the connecting plate 22 is flush with the upper end surface of the first blade 11.

[0041] Reference Figure 2 and Figure 5In order to enable the sawtooth body 21 to move in the installation groove 111, sliders 221 are integrally formed at the left and right ends of the connecting plate 22, and slide grooves 1111 are opened at the left and right groove walls of the installation groove 111. The slider 221 moves in the slide groove 1111, and the slide groove 1111 extends toward the notch of the installation groove 111, so that the sawtooth body 21 can move toward the notch of the installation groove 111. In order to prevent the slider 221 from easily escaping from the slide groove 1111, a limiting plate 1112 is welded at one end of the slide groove 1111 away from the bottom of the installation groove 111.

[0042] Reference Figure 2 and Figure 5 Since the first blade 11 is in an arc shape, when the sawtooth body 21 and the connecting plate 22 abut against the bottom of the mounting groove 111, there are gaps between the left and right ends of the connecting plate 22 and the sawtooth body 21 and the left and right groove walls of the mounting groove 111, and there is also a gap between the slider 221 and the bottom of the slide groove 1111, so that when the slider 221 moves to abut against the limit plate 1112, the left and right ends of the connecting plate 22 can abut against the left and right groove walls of the mounting groove 111, and the slider 221 also abuts against the bottom of the slide groove 1111, and the sawtooth body 21 can move out of the mounting groove 111.

[0043] Reference Figure 4 and Figure 5 In order to fix the sawtooth body 21 in the installation groove 111 when the sawtooth body 21 is not in use, a clamping column 23 is welded at the upper end of the connecting plate 22, and a connecting block 113 is welded at the upper end of the first blade 11 near the opening 112. A clamping groove 114 is opened at one end of the connecting block 113 facing the clamping column 23, so that when the connecting plate 22 abuts against the bottom of the installation groove 111, the clamping column 23 can be clamped into the clamping groove 114, and the upper end of the clamping column 23 protrudes from the clamping groove 114, so that when the sawtooth body 21 needs to be used, the upper end of the clamping column 23 can be pulled to make the clamping column 23 disengage from the clamping groove 114.

[0044] Reference Figure 2 , Figure 5 and Figure 6 In order to shield and protect the sawtooth body 21 when the sawtooth body 21 is not in use, a blade assembly 3 is arranged at the slot position of the mounting slot 111, and the left and right ends of the blade assembly 3 are respectively abutted against the left and right slot walls of the mounting slot 111, and the blade assembly 3 includes an integrally formed first blade plate 31 and a second blade plate 32, and the cross-section of the first blade plate 31 and the second blade plate 32 is in the shape of a "7".

[0045] Reference Figure 5 , Figure 6 and Figure 7In order to fix the first blade plate 31 and the second blade plate 32 in the installation groove 111, a clamping block 321 is welded at the left and right ends of the second blade plate 32, and a first clamping groove 1113 that cooperates with the clamping block 321 is opened at the corresponding positions of the left and right groove walls of the installation groove 111. In this embodiment, in order to improve the stability of the first blade plate 31 and the second blade plate 32 when they are fixed to the groove wall of the installation groove 111, four clamping columns 23 are preferably provided on the second blade plate 32, and the four clamping columns 23 are divided into two groups, two in each group, and are respectively provided at the left and right ends of the clamping columns 23. When the sawtooth body 21 is not needed, the second blade plate 32 located on the first blade 11 and the second blade plate 32 located on the second blade 12 can be engaged with each other to prune branches that are not very hard.

[0046] Reference Figure 2 , Figure 5 , Figure 6 and Figure 8 When the sawtooth body 21 moves to the point where the slider 221 abuts against the limit plate 1112, a gap is left between the connecting plate 22 and the bottom of the mounting groove 111. In order not to affect the use of the sawtooth body 21, the first blade plate 31 and the second blade plate 32 are placed between the connecting plate 22 and the bottom of the mounting groove 111. At this time, the first blade plate 31 abuts against the bottom of the mounting groove 111, and the second blade plate 32 abuts against the connecting plate 22. In order to fix the first blade plate 31 and the second blade plate 32 between the bottom of the mounting groove 111 and the connecting plate 22, a second clamping groove 1114 that cooperates with the clamping block 321 is opened at the corresponding positions on the left and right groove walls of the mounting groove 111.

[0047] Reference Figure 2 , Figure 6 , Figure 7 and Figure 8 At this time, there is a gap between the end of the second blade plate 32 that is away from the first blade plate 31 and the bottom of the installation groove 111. In order not to affect the stability of the sawtooth body 21 when in use, a pair of reinforcing columns 1115 are welded at the edge of the groove of the second clamping groove 1114. The pair of reinforcing columns 1115 are respectively located on the left and right sides of the groove of the second clamping groove 1114. A reinforcing groove 322 that is firmly matched with the reinforcing column 1115 is opened at the corresponding position of the clamping block 321. The reinforcing groove 322 is opened downward from the clamping column 23 located above until it passes through the second blade plate 32. After the reinforcing groove 322 is aligned with the reinforcing column 1115, the first blade plate 31 and the second blade plate 32 are inserted into the bottom of the installation groove 111 and between the connecting plate 22.

[0048] The implementation principle of the pruning shears blade set of the embodiment of the present application is as follows: for branches that are not very hard, the second blade plate 32 located on the first blade 11 and the second blade plate 32 located on the second blade 12 can be engaged to perform pruning. When a branch that is not easy to be pruned by the second blade plate 32 appears, the first blade plate 31 and the second blade plate 32 are removed, and the clamping column 23 is pulled to pull the clamping column 23 out of the clamping groove 114, and the sawtooth body 21 is driven by the clamping column 23 to move in a direction away from the bottom of the installation groove 111, and moves until the slider 221 abuts against the limit plate 1112. When the reinforcing groove 322 is aligned with the reinforcing column 1115, the first blade plate 31 and the second blade plate 32 are inserted into the bottom of the mounting groove 111 and the connecting plate 22. When inserting, due to the setting of the clamping block 321, a certain force needs to be applied to the first blade plate 31 and the second blade plate 32 before they can be inserted. After the first blade plate 31 and the second blade plate 32 are inserted between the bottom of the mounting groove and the connecting plate 22, harder branches can be pruned. The setting of the sawtooth body 21 enables the user to prune harder branches more easily without causing arm soreness.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
