Description

Technical Field

[0001] The utility model relates to the field of installation tools, in particular to a tool with an anti-dropping structure. Background Art

[0002] When fixing or connecting wire harnesses for electrical equipment, connectors (such as screws) are usually required for fixing. For fixing positions with a relatively large contact surface, users can manually assist in holding the screw, and then use an installation tool (such as a screwdriver) to tighten and fix it. However, when the fixing position is in a narrow space such as a hole or a cavity, since users cannot align the bottom of the screw with the corresponding fixing hole of the fixing position by hand, it is necessary to use a screwdriver or a corresponding tool to send the bottom of the screw to the corresponding position, and then use a screwdriver to tighten and fix it. To solve this problem, magnetic screwdrivers are usually used to send the screw to the corresponding position. However, the fixing method of magnetic screwdrivers also has the following problems:

[0003] (1) Due to the limited suction force at the top of the screwdriver, when the weight of the attracted screw is relatively large, the suction force cannot firmly hold the screw. When sending the screw to the fixing position, the screw may fall off due to shaking, and thus cannot be sent to the corresponding fixing position.

[0004] (2) For some screws made of alloy or polymer materials, since they do not contain iron elements or contain a low amount of iron elements, the magnetic screwdriver cannot attract the screw, and thus cannot fix the screw. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a tool with an anti-dropping structure. After the installation head is docked with the connector, the gripper mechanism can firmly hold the connector and send it to the position to be fixed for tightening and fixing, preventing the connector from falling off during the transfer and installation process, and improving the installation efficiency.

[0006] To achieve the above purpose, the utility model is realized by the following technical solutions:

[0034] Embodiment 1:

[0035] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the following will further describe the embodiments of the present utility model in detail with reference to the accompanying drawings.

[0036] This embodiment provides a tool with an anti-detachment structure, such as Figure 1 and Figure 2As shown in the figure, it includes a tool body 1, a gripper mechanism 2, a pushing component 3 and a mounting head 5. The mounting head 5 is directly or indirectly connected to the head of the tool body 1. The gripper mechanism 2 is connected to the pushing component 3, and under the action of the pushing component 3, the gripper mechanism 2 can move along the tool body 1.

[0037] Specifically, as Figure 2 shown, the tool body 1 includes a rod body 12 and a handle 11. The handle 11 is fixedly connected to one end of the rod body 12. The rod body 12 has a hollow structure inside. The rod body 12 is provided with at least one through groove 13. The through groove 13 is arranged along the axial direction of the rod body 12, and the length of the through groove 13 is less than the length of the rod body 12.

[0038] In the hollow cavity of the rod body 12, there is a pushing component 3. As Figure 4 shown, the pushing component 3 includes a sliding rod 32 and a pushing block 31 connected to one end of the sliding rod 32. The pushing block 31 protrudes from the through groove 13, and by operating the pushing component 3, the sliding rod 32 moves inside the rod body 12.

[0039] In this embodiment, in order to facilitate the operation of the pushing block 31, the pushing block 31 and the sliding rod 32 form a T-shaped structure. Two through grooves 13 are correspondingly arranged, and both ends of the pushing block 31 protrude from the corresponding through grooves 13 respectively. It can be understood that in other embodiments, the pushing block 31 can also be in other forms. For example, the pushing block 31 and the sliding rod 32 form an L-shaped structure, and one through groove 13 is provided, that is, a single-side operation mode is formed; the pushing block 31 can also be set as T-shaped, cross-shaped, etc., and the number of through grooves 13 changes accordingly with the shape of the pushing block 31.

[0040] As Figure 5 shown, a spring 33 is sleeved outside the sliding rod 32. One end of the spring 33 is limited by the pushing block 31. In order to hold the spring 33 sleeved on the sliding rod 32, as Figure 10 shown, the inside of the rod body 12 is provided with a hollow structure with two inner diameters, that is, a first cavity and a second cavity with different diameters are formed inside the rod body 12. The two ends of the first cavity with a larger diameter are respectively communicated with the second cavity, and a limiting platform is formed at the connection between the second cavity and the first cavity to limit the spring 33, so that after the pushing component 3 unloads the pressure, the spring 33 can drive the pushing component 3 to return to its original position, and then drive the gripper 24 to reset.

[0041] Since the size of the sliding rod 32 is the same as the minimum inner diameter of the rod body 12, when the pushing rod 3 pushes the gripper mechanism 2, the spring 33 will be compressed. When the pressure is unloaded, the pushing rod 3 will reset under the action of the spring 33.

[0042] In order to realize the connection with the gripper mechanism 2, a fixing block 34 is installed at the other end of the sliding rod 32. As Figure 3 shown, the fixing block 34 also protrudes from the through groove 13, and its structural form is adapted to the number of through grooves 13.

[0043] The gripper mechanism 2 includes a sliding block 21 and grippers 24. The sliding block 21 is connected to at least two grippers 24, such as a double-jaw structure, a triple-jaw structure, a quadruple-jaw structure, etc. In this embodiment, considering the simplicity of the structure, two grippers 24 are adopted. As Figure 6 shown, the two grippers 24 are symmetrically installed on both sides of the sliding block 21. The two grippers 24 can be opened or closed relative to each other to achieve the operations of grasping or releasing.

[0044] The cross-sectional shape of the sliding block 21 can be set according to the actual situation. In this embodiment, as Figure 7 and Figure 8 shown, the sliding block 21 adopts a hexagonal cross-sectional structure. Two opposite surfaces of the sliding block 21 are provided with gripper mounting positions 22, and the gripper mounting positions 22 are grooves with a certain depth. The grippers 24 are rotatably connected to the gripper mounting positions 22. A tension spring 26 is provided in the gripper mounting position 22, and the inner surface of the gripper 24 is connected through the tension spring 26. Under the action of the tension spring 26, the gripper 24 performs the actions of grasping or releasing.

[0045] Since the gripper mechanism 2 needs to move along the rod body 12, a through hole 23 is axially opened in the sliding block 21. A fixing groove 27 adapted to the fixing block 34 is provided on the back side (the mounting side away from the gripper 24) of the sliding block 21. The fixing connection between the pushing component 3 and the gripper mechanism 2 is realized by the clamping connection of the fixing block 34 and the fixing groove 27.

[0046] As Figure 9 shown, the gripper 24 includes a connecting plate 241. One end of the connecting plate 241 is provided with an extended rotating rod 243. The gripper mounting position 22 is provided with a corresponding fixing hole 25. By inserting the rotating rod 243 into the fixing hole 25, the relative rotation between the gripper 24 and the sliding block 21 can be realized. The other end of the connecting plate 241 has a grasping opening 242, and the two grasping openings 242 cooperate to realize the grasping and fixing of the component. When the component is a screw, the grasping opening 242 is arc-shaped.

[0047] The shape of the connecting plate 241 can be set arbitrarily as long as the space between the connecting plates 241 can accommodate the connecting piece to be grasped. In this embodiment, the connecting plate 241 is set as an L-shaped plate, and the grasping opening 242 is arranged on the short side of the connecting plate 241.

[0048] To facilitate the connection between the gripper 24 and the tension spring 26, a raised block 244 is provided on the inner side of the connecting plate 241, and the tension spring 26 is fixedly connected to the raised block 244.

[0049] The mounting head 5 is used to cooperate with the connecting piece to be grasped. When the connecting piece to be grasped is a screw, the mounting head 5 is a screwdriver head. As Figure 2As shown, the mounting head 5 is directly connected to the rod body 12 of the tool body 1, and the mounting head 5 is aligned with the connecting part to be grasped, and then the gripper mechanism 2 slides to the mounting head 5 to further fix the part to prevent the part from falling off during the transfer process.

[0050] In order to better realize the opening and closing of the gripper mechanism 2, the mounting head 5 is connected to the rod body 12 through the opening block 4, that is, indirectly connected; Figure 1 As shown, the size of the expansion block 4 is larger than the diameter of the rod body 12 . When the gripping mechanism 2 slides to the expansion block 4 , the expansion block 4 expands the gripping hand 24 of the gripping mechanism 2 .

[0051] In this embodiment, the opening block 4 is in the shape of two truncated cones, wherein the faces of the truncated cones with larger diameters are butted. Since a tension spring 26 is connected between the gripper 24 and the sliding block 21, the closer the gripper 24 connection is to the opening block 4, the greater the distance between the two grippers 24 is, so as to facilitate grasping the roots of components such as screws.

[0052] Taking screws as an example, the working principle of this embodiment is described in detail:

[0053] According to the range of screw models, a suitable gripper mechanism 2 is selected to ensure that the gripper 24 of the gripper mechanism 2 can support the head of the screw when closed, fit the screw to the screwdriver head, and prevent the screw from falling.

[0054] When the screw needs to be sent to the fixed place, the push component 3 is pushed down first, and the push component 3 drives the gripper mechanism 2 to move. When the gripping opening 242 of the gripper mechanism 2 contacts the opening block 4, since both sides of the opening block 4 are conical structures, the gripper 242 will continue to expand under the action of the opening block 4 when the gripper mechanism 2 moves downward. When the sliding block 21 of the gripper mechanism 2 moves to contact the opening block 4, the gripper mechanism 2 moves to the lowest point. At this time, the gripping opening 242 of the gripper 24 and the screwdriver head leave space for placing the screw, which is used to place the screw.

[0055] When the screw is placed, the pressure on the push block 31 is unloaded. At this time, the spring 33 will rebound and push the assembly 3. The gripping openings 242 of the two grippers 24 will fit the fixing position of the screw with the screwdriver head, and then the screw can be sent to the place to be fixed and tightened. When the fixation is completed, press the push block 31 downward to make the grippers 24 loosen the screw and then pull out the tool.

[0056] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
