[0038] Please refer to Figure 1 , Figure 1 The diagram shows a perspective view of the support wrench 100 in some embodiments of this application. It is understood that the support wrench 100 generally includes a rotary wrench and a support wrench. The rotary wrench is typically used to tighten or loosen fasteners such as nuts and bolts by rotation. The support wrench is used to provide support and fixation. The support wrench 100 in this application is a support wrench.

[0039] The support wrench 100 includes a base 9, a first support member 1, a second support member 2, a connector 3, and a clamping assembly. The first support member 1 is configured to be controllably rotatably connected to the base 9 about a first axis. The second support member 2 is configured to be controllably movably connected to the first support member 1 along the extending direction of the first support member 1. The connector 3 is fixedly connected to the second support member 2. The clamping assembly includes a clamping member 4, which is configured to be controllably movably connected to the connector 3; the clamping member 4 is responsive to relative movement between the first support member 1 and the base 9, and / or relative movement between the first support member 1 and the second support member 2, and can move toward or away from the base 9 to clamp the part 4 to be clamped between the clamping member 4 and the base 9.

[0040] The base 9 is the foundation for supporting the wrench 100. It can be a plate or block shape or other structures that are easy to install. There are no restrictions on this.

[0041] The first support member 1 is a component used to adjust the angle between the clamping member 4 and the base 9, so that the clamping member 4 can flexibly change its angle relative to the base 9 within a certain range, thereby adapting to the different usage requirements of the clamping member 4.

[0042] The second support member 2 is a component used to adjust the distance between the clamping member 4 and the base 9, so that the clamping member 4 can quickly approach and move away from the base 9, so as to quickly press the member to be clamped 4 between the base 9 and the clamping member, and to allow the member to be clamped to quickly detach from the support wrench 100 when it is necessary to remove the member to be clamped.

[0043] The connector 3 is a component that connects the clamping member 4 and the second support member 2. The clamping member 4 can be installed on the connector 3.

[0044] The clamping member 4 and the base 9 together clamp the part to be clamped 4 between the clamping member 4 and the base 9, thus fixing the part to be clamped 4.

[0045] When it is necessary to clamp the part 4, the operator can hold the first support 1 and the base 9, adjust the relative position between the first support 1 and the base 9, and adjust the relative position between the first support 1 and the second support 2 to change the relative position between the clamping part 4 and the base 9, so that the part 4 to be clamped is clamped between the clamping part 4 and the base 9. Then, the wrench 100 is rotated, so that the part 4 to be clamped is driven to rotate by the support wrench 100. The entire process can adjust the relative position between the clamping part 4 and the base 9 according to the shape and size of the part 4 to be clamped, so that the part 4 to be clamped can be clamped stably and reliably without the need to change to a different size support wrench 100, thus improving the operator's ease of operation.

[0046] In some embodiments of this application, reference continues to be made to Figure 1 and in conjunction with reference Figure 2 , Figure 2 It shows Figure 1 The diagram shows a three-dimensional view of the support wrench 100 from another perspective. The connecting member 3 has a receiving cavity A. The support wrench 100 also includes a driving member 5, a first gear 6, and a second gear 7. The first gear 6 is located in the receiving cavity A and is rotatably connected to the connecting member 3. The first gear 6 is driven by the driving member 5. The second gear 7 is located in the receiving cavity A and is rotatably connected to the connecting member 3. The first gear 6 and the second gear 7 mesh with each other, and the number of teeth on the second gear 7 is greater than the number of teeth on the first gear 6. The clamping member 4 has a meshing part 41, which is a rack 41a. The rack 41a meshes with the second gear 7. The extension directions of the central axis of the first gear 6, the central axis of the second gear 7, and the first axis are parallel to each other.

[0047] Thus, the driving component 5 drives the first gear 6 to rotate. Since the first gear 6 meshes with the second gear 7, the second gear 7 is also driven to rotate. The second gear 7 has a larger number of teeth than the first gear 6. It can be understood that the number of teeth on a gear is inversely proportional to its rotational speed. With a fixed transmission ratio, a gear with more teeth experiences a greater reduction in rotational speed. Therefore, the second gear 7 has more teeth and a larger diameter, resulting in a lower rotational speed than the first gear 6 when meshing with it. Furthermore, according to the relationship between torque and rotational speed, the torque increases as the rotational speed decreases. Because the second gear 7 rotates at a lower speed, its output torque is greater than that of the first gear 6, thereby generating a greater clamping force on bolts and other components with the support wrench 100, improving the tightening effect.

[0048] The meshing of rack 41a and second gear 7 forms a rack and pinion transmission mechanism. By controlling the rotation angle and direction of the second gear 7, rack 41a can be precisely driven to move linearly along its length. Due to the high precision of gear transmission, it is possible to control the minute displacement of clamping member 4, thereby precisely adjusting the distance between clamping member 4 and base 9 to accommodate clamping members 4 of different sizes. Furthermore, after rack 41a meshes with second gear 7, the rotation of second gear 7 is converted into linear motion of clamping member 4 through rack 41a. Because second gear 7 has a large number of teeth and a large diameter, it has a larger lever arm when transmitting torque, which can further amplify the torque and increase the clamping force of clamping member 4. When the second gear 7 rotates, the meshing point between the teeth of the second gear 7 and the rack 41a is far from the central axis, thereby generating a larger linear velocity and thrust on the rack 41a, enabling the clamping member 4 to act on the clamping member 4 with a larger clamping force, further improving the fastening effect of the support wrench 100.

[0049] In some embodiments of this application, reference continues to be made to Figure 1 and Figure 2 and in conjunction with reference Figure 3 , Figure 3 It shows Figure 1 The diagram shows a partial structure of the support wrench 100. The driving component 5 includes a driving gear 52 and a driving shaft 51. The driving shaft 51 drives the driving gear 52 to rotate around the central axis of the driving gear 52. The driving gear 52 meshes with the first gear 6. The number of teeth of the driving gear 52 is less than the number of teeth of the first gear 6. The central axis of the driving gear 52 is parallel to the extension direction of the central axis of the first gear 6, the extension direction of the central axis of the second gear 7, and the extension direction of the first axis.

[0050] The drive unit 5 also includes a drive gear 52 and a drive shaft 51. The operator manually rotates the drive shaft 51, causing the drive gear 52 connected to the drive shaft 51 to rotate. Through the meshing of the drive gear 52 with the first gear 6, power is transmitted to the first gear 6, thereby driving the entire transmission system. Since the number of teeth on the drive gear 52 is less than the number of teeth on the first gear 6, according to the principle of gear transmission, the torque will be amplified during the transmission process. This converts the smaller torque output by the drive unit 5 into a larger torque to meet the torque requirements of the support wrench 100 when clamping the part 4 to be clamped, thereby enhancing the clamping force and improving the tightening effect.

[0051] In some embodiments of this application, reference continues to be made to Figures 1 to 3 and in conjunction with reference Figure 4 , Figure 4 It shows Figure 1The rear view of the support wrench 100 shows that the clamping assembly also includes a locking member 8, which is threaded onto the side wall of the connector 3. The locking member is capable of moving toward or away from the second gear 9 in response to the rotational force acting on it, so that the locking member 8 has a retracted state abutting against the end face of the second gear 7 and an unlocked state separated from the second gear; the extension direction of the first axis is parallel to the extension direction of the second axis.

[0052] Thus, when the operator uses this support wrench 100, the operator manually rotates the drive shaft 51, causing the drive gear 52 connected to the drive shaft 51 to rotate. Through the meshing of the drive gear 52 with the first gear 6, power is transmitted to the first gear 6, and then to the second gear 7 meshing with the first gear 6. The second gear 7 then transmits power to the rack 41a, thereby causing the clamping member 4 to move. When the clamping member 4 moves into position, the clamping member 4 is between the clamping member 4 and the base 9, and the locking member 8 abuts against the end face of the second gear 7, allowing the second gear 7 to stop rotating and no longer press on the clamping member 4, thus improving the fixing accuracy of the support wrench 100.

[0053] In some other embodiments, the quick-stop support wrench 100 can be achieved by providing an electronic control device on the drive member 5 or the second gear 7.

[0054] In some embodiments of this application, reference continues to be made to Figures 1 to 4 The locking element 8 and the connecting element 3 are detachably connected.

[0055] Thus, when the gears in the support wrench 100 move, the locking member 8 is not connected to the connecting member 3, reducing the risk of affecting the gear movement. After the clamping member 4 is in place, the locking member 8 connects to the connecting member 3 and abuts against the end face of the second gear 7, achieving quick locking of the support wrench 100. Specifically, in this application, the locking member 8 can be set as a bolt.

[0056] In some embodiments of this application, reference continues to be made to Figures 1 to 4 The connector 3 is detachably connected to the second support 2.

[0057] By making the connector 3 and the second support 2 detachable, when components are damaged, maintenance personnel can easily disassemble and replace them without replacing the entire support wrench 100 or extensively disassembling its structure, thus reducing maintenance costs and time. Furthermore, the detachable connection method makes the assembly of the connector 3 and the second support 2 more convenient and faster during the manufacturing or assembly process of the support wrench 100. Operators can pre-assemble and test each component individually before assembling them together, improving the production efficiency and assembly quality of the support wrench 100. Moreover, the connector 3 and the second support 2 can be disassembled during transportation and storage, saving space. The method of detachable connection is not limited here; threaded connections, snap-fit ​​connections, etc., can be used.

[0058] In some embodiments of this application, reference continues to be made to Figures 1 to 4 The second support member 2 has a receiving hole B; the connector 3 has a first sub-part 31, a second sub-part 32 and a third sub-part 33 connecting the first sub-part 31 and the second sub-part 32; the first sub-part 31 has a first end D1 facing away from the third sub-part 33, and the second sub-part 32 has a second end D2 facing away from the third sub-part 33; the first end D1 and the second end D2 can move closer to each other in response to the action of external force and retract into the receiving hole B; the clamping member 4 is movably connected to the third sub-part 33.

[0059] By designing the connector 3 with a first sub-part 31, a second sub-part 32, and a third sub-part 33, when it is necessary to install the connector 3 into the receiving hole B of the second support member 2, only an external force needs to be applied to bring the first end D1 and the second end D2 closer together, allowing the connector 3 to be folded and placed into the receiving hole B. This design simplifies the installation process, eliminating the need for complex tools or cumbersome operating steps, and improving the efficiency of connection and disassembly between the connector 3 and the second support member 2. Furthermore, this installation method only requires the receiving hole B to be made on the second support member 2, without the need for other complex components that could damage the second support member 2. Specifically, when the clamping member 4 moves relative to the third sub-part 33, the clamping member 4 and the third sub-part 33 are always in contact, with the third sub-part 33 providing support to the clamping member 4, reducing the risk of the clamping member 4 falling off due to gravity.

[0060] In some embodiments of this application, reference continues to be made to Figures 1 to 4 and in conjunction with reference Figure 5 , Figure 5 It shows Figure 1 The front view of the support wrench 100 shows the first sub-part 31 and the second sub-part 32 being threaded together.

[0061] The first sub-part 31 and the second sub-part 32 are configured as a threaded connection, so that when maintenance and adjustment of the components between the first sub-part 31 and the second sub-part 32 are required, the threaded connection allows for fine adjustment of the relative position between the first sub-part 31 and the second sub-part 32.

[0062] In some embodiments of this application, reference continues to be made to Figures 1 to 5 The second support member 2 has a guide hole C, which extends along the extension direction of the first support member 1. The first support member 1 passes through the guide hole C so that the first support member 1 and the second support member 2 can move relative to each other in the extension direction of the first support member 1.

[0063] This allows the second support 2 to move relative to the first support 1 along the extending direction of the first support 1, enabling further adjustment of the position of the clamping member 4. The guide hole C provides a clear movement path for the first support 1, allowing it to move linearly along its own extending direction, preventing deviation or wobbling during movement and improving stability and accuracy. Furthermore, the design of the guide hole C simplifies the assembly of the first support 1 and the second support 2. During assembly, simply align the first support 1 with the guide hole C and insert it; no complex alignment or positioning operations are required, improving assembly efficiency and reducing assembly difficulty and cost.

[0064] In some embodiments, continue to refer to Figures 1 to 5 The support wrench 100 includes a pointer, which is fixedly connected to the second support 2. The scale lines are located on the pointer's travel path. The combination of the scale lines and the pointer visually displays the relative positional relationship between the first support 1 and the second support 2. During operation of the support wrench 100, the operator can observe the scale indicated by the pointer to understand the current position and tension of the clamping element 4, thereby achieving precise control and adjustment of the clamping force. In repetitive tasks, the scale lines and pointer help the operator quickly set the support wrench 100 to the same working position, ensuring that the same clamping force is applied each time, improving work efficiency and consistency, and significantly shortening operation time and increasing production efficiency.

[0065] In some embodiments, continue to refer to Figures 1 to 5 A buffer pad is provided at one end of the clamping member 4 near the base 9, and the buffer pad is fixedly connected to the engaging part 41. The buffer pad is usually made of a soft and elastic material, such as rubber, silicone, or foam. During the clamping process, the buffer pad is in direct contact with the clamped member 4, which can effectively reduce direct collision or friction between the hard surface of the clamping member 4 and the clamped member 4, thereby reducing the risk of scratches, indentations, or damage to the surface of the clamped member 4.

[0066] In the technical solution of this application embodiment, since the wrench assembly includes a rotary wrench and a support wrench 100 as described in any of the above embodiments, the rotary wrench is used to rotate the part to be clamped, and the support wrench is used to fix the part to be clamped. Therefore, it also has the advantages of any of the above embodiments.

[0067] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0068] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
