[0002] A bench vise, also known as a vise, is a general-purpose clamping tool used to hold workpieces. It is mounted on a workbench to securely hold the workpiece during machining and is an essential tool in a fitter's workshop. Currently, most bench vises have fixed bases, with mounting holes pre-drilled in the workbench surface, and the vise is fixed to the workbench with bolts. When there are no mounting holes drilled in the workbench, the vise cannot be fixed, limiting its normal use and causing inconvenience to the user.

[0003] Chinese Patent No. CN219788034U discloses a pipe clamping vise, including an L-shaped clamping arm and a clamping rod. The L-shaped clamping arm is fixed to the bottom of a base, and a connecting seat is fixed to its end. The connecting seat has a vertical screw hole. The clamping rod is a screw rod, which is vertically screwed into the screw hole. A rotating handle is fixed to the bottom of the clamping rod, and a pressure plate is fixed to its top. The above structure allows the vise to be easily fixed to the installation position. However, installing or disassembling this vise requires rotating the clamping rod multiple times in either the forward or reverse direction, which affects the efficiency of the vise's installation and disassembly, causing inconvenience to the user. Utility Model Content

[0004] This utility model addresses the existing technical problems by providing a bench vise.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A bench vise includes a bench vise body and a clamping component. The bench vise body is mounted on the clamping component. The clamping component includes a clamping arm, a locking member, and a clamping screw. The lower end of the clamping arm is provided with a clamping seat. The locking member and the clamping screw are mounted on the clamping seat. The locking member is used to unlock or lock the clamping screw. A clamping space is provided between the clamping seat and the bench vise body.

[0006] Based on the above technical solution, the present invention can be further improved as follows:

[0007] Preferably, the clamping seat has a vertically arranged guide hole and a horizontally arranged receiving groove. The guide hole communicates with the receiving groove. An elastic element and the locking element are installed in the receiving groove. The locking element is movably installed in the receiving groove. The locking element has a mounting hole that corresponds to the guide hole. The clamping screw is installed in the mounting hole and the guide hole. One side of the mounting hole has an internal thread. The elastic element is used to drive the internal thread of the locking element to engage with the clamping screw.

[0008] Preferably, the locking member is cuboid in shape, and a guide rod is provided on the locking member. One end of the elastic member abuts against the inner wall of the receiving groove, and the other end is sleeved on the guide rod.

[0009] Preferably, it also includes a connecting seat, the vise body is mounted on the connecting seat, the clamping arm and the connecting seat are an integral structure, and the clamping arm and the connecting seat are C-shaped as a whole.

[0010] Preferably, the vise body includes a vise body assembly and a base, the vise body assembly is mounted on the base, and the clamping arm is connected to the base.

[0011] Preferably, the connecting seat is provided with an arc-shaped groove, the base of the vise body is provided with a through hole, one end of the bolt passes through the arc-shaped groove and the through hole and is screwed to the fixing sleeve, and the fixing sleeve is located on the base.

[0012] Preferably, there are two arc-shaped grooves, which are located on both sides of the vise body.

[0013] Preferably, a guide block is installed on the bolt, and the guide block is adapted to the arc-shaped groove.

[0014] Preferably, the lower end of the base is provided with a positioning groove, and the connecting seat is provided with a corresponding positioning platform, the positioning platform being located within the positioning groove.

[0015] The beneficial effects of this utility model are as follows: By installing a clamping component on the base, during use, the vise body is placed on the workbench surface, with the side of the workbench located within the clamping space. The locking component unlocks the clamping screw, and the internal thread of the locking component disengages from the external thread of the clamping screw, allowing the clamping screw to move upward quickly and with a large stroke. When the clamping screw contacts the bottom surface of the workbench, the locking component locks the clamping screw, meaning the thread of the locking component engages with the thread of the clamping screw. The clamping screw moves upward by engaging with the thread of the locking component, clamping the workbench. Furthermore, the elastic component ensures that the locking component and the clamping screw are firmly locked, preventing the threads from disengaging and ensuring stable clamping of the workpiece. When the vise needs to be removed, the locking component unlocks the clamping screw again, separating the locking component from the clamping screw, achieving rapid separation of the clamping screw from the workbench. This allows for quick assembly and disassembly of the vise from the workbench, improving the efficiency of vise assembly and disassembly and enhancing user convenience. Attached Figure Description

[0021] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0022] like Figures 1 to 4 As shown, this utility model discloses a bench vise, including a bench vise body and a clamping component. The bench vise body is mounted on the clamping component. The clamping component includes a clamping arm 9, a locking member 10, and a clamping screw 12. The lower end of the clamping arm 9 is provided with a clamping seat. The locking member 10 and the clamping screw 12 are mounted on the clamping seat. The locking member 10 is used to unlock or lock the clamping screw 12. A clamping space is provided between the clamping seat and the bench vise body.

[0023] In this embodiment, the clamping seat is provided with a vertically arranged guide hole and a horizontally arranged receiving groove. The guide hole communicates with the receiving groove. An elastic element 11 and a locking element 10 are installed in the receiving groove. The locking element 10 is movably installed in the receiving groove. The locking element 10 is provided with a mounting hole, the inner diameter of which is larger than the outer diameter of the clamping screw 12. The mounting hole corresponds to the guide hole. The clamping screw 12 is installed on the mounting hole and the guide hole. One side of the mounting hole is provided with an internal thread 10.1. The elastic element 11 is used to drive the internal thread 10.1 of the locking element 10 to engage with the external thread of the clamping screw 12. Specifically, the internal thread 10.1 is located on the side close to the elastic element 11. One end of the elastic element 11 abuts against the inner wall of the receiving groove, and the other end abuts against the locking element 10. The elastic element 11 applies a force to the locking element 10, causing the internal thread 10.1 of the locking element 10 to engage with the external thread of the clamping screw 12. When the locking member 10 unlocks the clamping screw 12, it overcomes the elastic force of the elastic member 11 and presses the locking member 10, causing the internal thread 10.1 of the locking member 10 to separate from the clamping screw 12, that is, the locking member 10 and the clamping screw 12 are disengaged. When the locking member 10 locks the clamping screw 12, under the action of the elastic member 11, the internal thread 10.1 connects with the clamping screw 12, that is, the internal thread 10.1 and the clamping screw 12 are threadedly engaged. When the clamping screw 12 is rotated, the clamping screw 12 moves along the internal thread 10.1 toward the vise body, thereby fixing the vise body on the workbench.

[0024] Furthermore, the elastic element 11 is a spring, and the locking element 10 is rectangular. The locking element 10 is provided with a guide rod 14, and one end of the elastic element 11 is sleeved on the guide rod 14. The guide rod 14 plays a guiding and positioning role for the elastic element 11, preventing the elastic element 11 from shifting or getting stuck, and ensuring that the elastic element 11 can extend and retract normally.

[0025] Furthermore, a clamping seat is installed at the upper end of the clamping screw 12, and a handle 13 is installed at the lower end. By rotating the handle 13, the clamping screw 12 moves upward, causing the vise body to engage with the clamping seat, thus firmly fixing the vise to the workbench. The clamping seat increases the contact area with the workbench, further improving the stability of the vise installation.

[0026] In this embodiment, the clamping component further includes a connecting seat 15, on which the vise body is mounted. The clamping arm 9 and the connecting seat 15 are an integral structure, and the clamping arm 9 and the connecting seat 15 are C-shaped as a whole. This increases the overall structural strength, reduces the number of parts, improves assembly efficiency, and enhances the overall stability of the vise.

[0027] The vise body includes a vise body assembly and a base 1. The vise body assembly is mounted on the base 1. The connecting seat 15 has an arc-shaped groove 16. The base 1 of the vise body has a through hole. One end of a bolt 17 passes through the arc-shaped groove 16 and the through hole and is screwed onto a fixing sleeve 18. The fixing sleeve 18 is located on the base 1 and has an operating handle mounted on it. When the vise body is rotated, the bolt 17 moves along the arc-shaped groove 16. When rotated to a designated position, the fixing sleeve 18 is rotated by the operating handle, causing the bolt 17 to screw into the fixing sleeve 18, thereby firmly connecting the base 1 and the connecting seat 15 together. This meets the usage requirements of the vise body at various angles and further improves the ease of use.

[0028] In an optional embodiment, the clamping arm 9 is directly connected to the base 1, which can also achieve the function of quickly fixing the bench vise to the workbench.

[0029] Furthermore, two arc-shaped grooves 16 are provided, located on both sides of the vise body, which increases the stability of the vise body during rotation, achieves uniform force on both sides, and ensures the firmness of the vise body installation.

[0030] Furthermore, a guide block 19 is installed on the bolt 17, and the guide block 19 is adapted to the arc-shaped groove 16. The guide block 19 is located in the arc-shaped groove 16, and the guide block 19 cooperates with the arc-shaped groove 16 to guide the vise body and ensure its smooth rotation.

[0031] Furthermore, the lower end of the base 1 is provided with a positioning groove 20, and the connecting seat 15 is provided with a corresponding positioning platform, which is located within the positioning groove 20. The positioning groove 20 and the positioning platform cooperate to facilitate the installation of the base 1 and the connecting seat 15, thereby improving the ease of assembly.

[0032] The clamp assembly includes a movable clamp body 2, a fixed clamp body 3, and a lead screw 4. The fixed clamp body 3 is fixedly connected to the base 1, and the base 1 is provided with a slide rail 8. The movable clamp body 2 is slidably mounted on the slide rail 8. One end of the lead screw 4 is equipped with a handle 5, and the other end of the lead screw 4 passes through the fixed clamp body 3 and is threadedly connected to the movable clamp body 2. The movable clamp body 2 and the fixed clamp body 3 cooperate to form a main jaw 6 and a secondary jaw 7, with the main jaw 6 located above the secondary jaw 7. The main jaw 6 and the secondary jaw 7 have different structures; specifically, the main jaw 6 is a flat jaw, and the secondary jaw 7 is a pipe clamp jaw, meeting the clamping needs of parts with different shapes and improving the range of applications.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
