[0042] To fully understand this application, detailed steps and structures will be presented in the following description to illustrate the technical solution of this application. Preferred embodiments of this application are described in detail below; however, in addition to these detailed descriptions, this application may have other implementation methods.

[0043] This embodiment provides a workbench 100, such as Figure 1 , Figure 2 As shown, the workbench 100 includes a tabletop 101 and a tabletop frame 102, with the tabletop 101 mounted on the tabletop frame 102. An extension bracket can be mounted on the tabletop frame 102 and arranged along the tabletop 101. The extension bracket includes a bracket body 1 and a locking structure 2. The bracket body 1 is used to support tools by being positioned above the tabletop 101 of the workbench 100, and at least one end of the bracket body 1 is detachably fixed to the tabletop frame 102 of the workbench 100 via the locking structure 2.

[0044] like Figure 3 As shown, the locking structure 2 includes: a fixed frame 21, a locking block 22, an operating handle 23, and a handle locking structure 24; the fixed frame 21 is fixed to the end of the support body 1, one end of the locking block 22 is hinged to the fixed frame 21, and the other end can be fastened to the edge of the workbench 100; one end of the operating handle 23 is hinged to the fixed frame 21, and the other end is for the user to push and pull, the operating handle 23 is connected to the locking block 22, and can drive the locking block 22 to rotate; the handle locking structure 24 is connected to the operating handle 23 and is used to lock the operating handle 23 to restrict its rotation.

[0045] The workbench 100 and its extension bracket provided in this application embodiment have two ends of the bracket body 1 that can be detachably fixed to the tabletop frame 102 of the workbench 100 via locking structures 2. One end of the operating handle 23 is hinged to the fixing frame 21, and the other end is for the user to push and pull. The operation is simple. The operating handle 23 can drive the locking block 22 to rotate, thereby fixing or separating the tabletop frame 102. The handle locking structure 24 can lock the operating handle 23 to restrict its rotation and prevent the locking block 22 from loosening when fixed to the tabletop frame 102. Therefore, the workbench 100 and its extension bracket provided in this application embodiment have simple and easy-to-operate installation, fixing and disassembly methods for the extension bracket, which allows users to use or remove the extension bracket as needed, enabling the workbench 100 to be better adjusted under various usage requirements.

[0046] The locking principle of the extension bracket provided in this application embodiment includes the following aspects:

[0047] 1. Locking block 22 is a component used to fasten the edge of the worktable 100 for fixation. When locking block 22 is fastened to the edge of the worktable 100, such as... Figure 1 As shown, the extension bracket cannot move along the first direction of the worktable 100. Since the locking block 22 is engaged with the edge of the worktable 100, the extension bracket also cannot move along the vertical direction of the table surface 101 of the worktable 100, thus achieving fixation with the worktable 100. Separation of the extension bracket from the worktable 100 only requires separating the locking block 22 from the edge of the worktable 100.

[0048] 2. The operating handle 23 is a component that is directly operated by the user. It plays the role of driving the locking block 22 to move and control the locking block 22 to engage or disengage from the edge of the worktable 100.

[0049] 3. The handle locking structure 24 is used to lock the operating handle 23 individually. That is, whether the operating handle 23 can be operated is determined by the state of the handle locking structure 24. When the handle locking structure 24 locks the operating handle 23, the operating handle 23 cannot be operated by the user, nor will it be loosened by tool vibration. Only when the user actively unlocks the handle locking structure 24 and then operates the operating handle 23 can the operating handle 23 be operated normally and drive the locking block 22 to move.

[0050] Therefore, the locking structure 2 provided in this embodiment has a stable locking effect and is relatively simple to operate.

[0051] In an alternative embodiment, such as Figure 4As shown, the handle locking structure 24 includes: a latching part 241, an operation button 242, and a rotating shaft 244. The latching part 241 is fixed to the fixing frame 21; the rotating shaft 244 is connected to the operating handle 23; the operation button 242 is connected to the operating handle 23 via the rotating shaft 244, and the operation button 242 includes a latch 2421; as shown... Figure 4 As shown, when the operation button 242 is rotated to the first position, the hook 2421 engages with the fastening part 241, as... Figure 5 As shown, when the operation button 242 is rotated to the second position, the hook 2421 separates from the fastening part 241. In this embodiment, the handle locking structure 24 uses a locking method in which the operation button 242 and the fastening part 241 cooperate to lock. The operation button 242 has a hook 2421 on one side. The hook 2421 and the fastening part 241 are matched. Only when the operation button 242 is rotated to the first position can the hook 2421 engage with the fastening part 241, thus restricting the rotation of the operation handle 23. When the user actively unlocks the handle, that is, actively presses the operation button 242, causing the operation button 242 to rotate to the second position, the hook 2421 separates from the fastening part 241, and the operation handle 23 can be rotated, causing the locking block 22 to separate from the edge of the worktable 100.

[0052] In an alternative embodiment, such as Figure 4 As shown, the handle locking structure 24 includes an elastic element 243, which abuts against the operation button 242 and the operation handle 23 to provide elastic force for holding the operation button 242 in a first position. In this embodiment, the elastic element 243 facilitates keeping the operation button 242 in the first position under normal conditions, thus locking the operation button 242 under normal conditions. This also ensures that the extension bracket in this embodiment remains locked to the workbench 100 under normal conditions. The elastic element 243 also allows the operation button 242 to automatically reset to the first position after being operated by the user, facilitating operation.

[0053] In an alternative embodiment, such as Figure 4 As shown, the elastic element 243 is a torsion spring, which is sleeved on the rotating shaft 244. In this embodiment, the installation method of the torsion spring is simple, effective, low-cost, and easy to put into actual production.

[0054] In an alternative embodiment, such as Figure 4As shown, the operating handle 23 has a cavity 231, within which the rotating shaft 244 and the operating button 242 are located. The side of the cavity 231 facing the mounting bracket 21 has an opening 232 for the operating button 242 to be exposed. In this embodiment, the cavity 231 within the operating handle 23 provides installation space for other components, increasing the utilization rate of structural space. Simultaneously, it conceals components such as the rotating shaft 244 and the operating button 242 within the overall structure, providing a certain degree of protection. The opening 232 facing the mounting bracket 21 ensures that the operable side of the operating button 242 is located inside the overall structure, which can prevent accidental activation by the user to some extent.

[0055] In an alternative embodiment, such as Figure 4 As shown, the operation button 242 includes a limiting block 2422, which protrudes from one side of the operation button 242 and abuts against the edge of the opening 232 to limit the range of rotation of the operation button 242. In this embodiment, the limiting block 2422 of the operation button 242 can limit the operation button 242 to a reasonable range of rotation, avoiding the operation button 242 from having an excessively large range of rotation that makes it difficult to operate.

[0056] In an alternative embodiment, such as Figure 4 As shown, the locking structure 2 also includes a connecting rod 25, with its two ends connected to the locking block 22 and the operating handle 23, respectively. In this embodiment, the connecting rod 25 facilitates the transmission of the operating handle 23, making it easier for the operating handle 23 to drive the locking block 22 to rotate.

[0057] In an alternative embodiment, such as Figure 4 As shown, the mounting bracket 21 includes an end cap 211, which covers the locking block 22, the operating handle 23 and the handle locking structure 24, and is used to protect the locking block 22, the operating handle 23 and the handle locking structure 24, thereby protecting the internal components.

[0058] In an alternative embodiment, such as Figure 4 As shown, the tabletop frame 102 has a protrusion 1021 on at least one side along the first direction, and the locking block 22 has a groove 221 corresponding to the position of the protrusion 1021. When the protrusion 1021 is inserted into the groove 221, the movement of the support body 1 in the direction perpendicular to the tabletop 101 is restricted. In this embodiment, by matching the shape of the locking block 22 with the tabletop frame 102, the range of motion of the support body 1 is more fully restricted, which is beneficial to keeping the extended support stable.

[0059] It should be understood that the above embodiments are exemplary and are not intended to encompass all possible implementations included in the claims. Various modifications and changes can be made to the above embodiments without departing from the scope of this disclosure. Similarly, the various technical features of the above embodiments can be arbitrarily combined to form other embodiments of this application that may not be explicitly described. Therefore, the above embodiments only illustrate several implementations of this application and do not limit the scope of protection of this patent application.
