Description

Technical Field

[0001] This utility model belongs to the field of construction tool technology, and in particular relates to a tightening tool for installing ventilation ducts in narrow spaces. Background Technology

[0002] When installing ventilation ducts in confined spaces, traditional tightening tools are difficult to use due to space constraints, resulting in inconvenience and low efficiency. Existing tightening tools are often long and inconvenient to carry, and their poor maneuverability in narrow spaces leads to installation difficulties. Therefore, there is an urgent need for a tightening tool that is simple in structure, flexible in operation, and suitable for installing ventilation ducts in confined spaces, in order to improve installation efficiency and convenience and meet the needs of actual engineering projects. Summary of the Invention

[0003] The purpose of this utility model is to provide a tightening tool for installing ventilation ducts in narrow spaces, in order to solve the problems of common tightening tools having a long structure and poor operational flexibility in narrow spaces.

[0004] This utility model achieves the above-mentioned objective through the following technical solution: it includes a sleeve head, a connecting block fixedly provided on one side of the sleeve head, a rotating shaft mounting block fixedly provided on one side of the connecting block, a handle rod provided above the rotating shaft mounting block, the handle rod and the rotating shaft mounting block being connected by a rotating shaft, a bearing being provided between the handle rod and the rotating shaft mounting block, a fastening round rod penetrating through the inner side of the handle rod, a cylindrical screw head with anti-slip teeth on one end of the fastening round rod, a groove being opened on the other side of the connecting block, and the other end of the fastening round rod being inserted into the inner side of the groove.

[0005] Furthermore, the handle is a Z-shaped handle.

[0006] Furthermore, the fastening rod has threads on its outer side, and the fastening rod is connected to the handle rod by thread engagement.

[0007] Furthermore, an anti-slip handle is fitted onto the outer side of one end of the handle.

[0008] Furthermore, the bearing is sleeved on the outside of the rotating shaft.

[0009] Beneficial effects: This utility model is reasonably designed and has the following beneficial effects:

[0010] In this utility model, by pushing and pulling the handle and connecting it with the bearing and rotating shaft mounting block, the rotating shaft mounting block drives the socket head to rotate, thereby tightening or loosening the screw, facilitating flexible operation in narrow spaces. The Z-shaped handle allows the long straight section of the handle to be closer to the back of the socket head, thus improving the labor-saving effect and reducing the user's labor intensity. The fastening rod and the handle are connected by a threaded engagement. Before use, one end of the fastening rod is inserted into the groove to facilitate the insertion of the tool and the alignment of the socket head with the screw. After the front fastening rod is unscrewed from the groove, the handle can be pushed and pulled to rotate the socket head, enhancing the stability and safety of the tool. The overall structure is simple and practical, improving the efficiency and convenience of ventilation duct installation in narrow spaces. Attached Figure Description

[0012] Figure 2 This is a cross-sectional view of the structure of this utility model.

[0013] In the diagram: 1-sleeve head, 2-connecting block, 3-shaft mounting block, 4-handle lever, 5-bearing, 6-fastening round rod, 7-cylindrical screw head, 8-groove, 9-anti-slip handle. Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Combination Figures 1 to 2 The tightening tool shown is for installing ventilation ducts in narrow spaces. It includes a socket head 1, a connecting block 2 fixedly mounted on one side of the socket head 1, a rotating shaft mounting block 3 fixedly mounted on one side of the connecting block 2, a handle 4 above the rotating shaft mounting block 3, the handle 4 and the rotating shaft mounting block 3 being connected by a rotating shaft, a bearing 5 between the handle 4 and the rotating shaft mounting block 3, a fastening rod 6 penetrating through the inner side of the handle 4, a cylindrical screw head 7 with anti-slip teeth on one end of the fastening rod 6, a groove 8 on the other side of the connecting block 2, and the other end of the fastening rod 6 being inserted into the groove 8.

[0016] Handle lever 4 is a Z-shaped handle.

[0017] The outer side of the fastening rod 6 is threaded, and the fastening rod 6 is connected to the handle rod 4 by thread engagement.

[0018] An anti-slip handle 9 is fitted on the outer side of one end of the handle 4.

[0019] Bearing 5 is mounted on the outside of the shaft.

[0020] Working principle: During use, the socket head 1 is aligned with the screw that needs to be tightened or loosened. At this time, the cylindrical screw head 7 at one end of the fastening rod 6 is inserted into the groove 8 on the other side of the connecting block 2, which plays a role in fixing and supporting. Rotate the fastening rod 6 to completely unscrew it out of the groove 8. At this time, the connecting block 2 is no longer restricted by the fastening rod 6. By pushing and pulling the Z-shaped handle 4, since there is a bearing 5 between the handle 4 and the rotating shaft mounting block 3, and the handle 4 and the rotating shaft mounting block 3 are connected by a rotating shaft, the pushing and pulling action can be smoothly converted into the rotational movement of the rotating shaft mounting block 3, which drives the socket head 1 to tighten or loosen the screw.

[0021] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0022] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
