[0002] Vise are a common tool in machining, handcrafting, and other fields. However, with the advancement of technology, especially in handcrafting, vises are needed to clamp fragile items such as circuit boards and resin models. Traditional vises have difficulty precisely controlling the clamping force, which may lead to damage to the clamped workpiece.

[0003] Therefore, there is an urgent need for a torque vise to solve the problem that traditional vises cannot accurately control the clamping force according to different materials. Summary of the Invention

[0014] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the implementation examples of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. The described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application.

[0015] The present invention will be further described below with reference to specific embodiments:

[0016] Referring to Figures 1-3, a torque vise is characterized by comprising: a spring (1), a central shaft (2), a positioning shaft (3), a lead screw (4), a ratchet plate (5), a movable block (6), an indicator block (7), a knob (8), a handle mounting shaft (9), a fixed housing (10), a handle head (11), a handle body (12), a movable part (13), a fixed part (14), a limit screw (15), and a fixing screw (16).

[0017] During assembly, the fixed housing (10) is fixed to the movable part (13) with screws (17), the lead screw (4) is placed in the through hole of the movable part (13), and the limiting screw (15) is tightened in the threaded hole (131). It should be noted that the limiting screw does not contact the lead screw (4) after being tightened, and only prevents the lead screw (4) from moving along the hole axis in the through hole. Then, the anti-rotation pin (21) on the central shaft (2) is inserted into the anti-rotation hole (52) of the ratchet plate (5), and then the positioning shaft (3) is placed in the circular groove of the central shaft (2). The assembly of the central shaft (2), ratchet plate (5) and positioning shaft (3) is placed in the center. Inside the fixed housing (10), the planar ratchet tooth A (41) meshes with the planar ratchet tooth B (51) on the ratchet plate (5); then the movable block (6) and the knob (8) are threaded together, and the above assembly is placed inside the fixed housing (10). The limit screw (15) is tightened, and the indicator block (7) is interference-fitted into the groove of the movable block (6). Then the anti-rotation hole on the handle mounting shaft (9) (not shown in the figure, but the form is the same as the anti-rotation hole (52) on the ratchet plate (5)) is placed in the anti-rotation shaft (22) on the central shaft (2), and the fixing screw (16) is tightened to complete the assembly, as shown in Figure 1. The remaining parts are conventional vise structures and will not be described in detail here.

[0018] In use, the knob (8) is rotated so that the movable block (6) moves along the through groove (102) to change the compression of the spring (1), thereby changing the elastic force that the spring (1) gives to the ratchet plate (5). Since the screw (4) and the fixed part (14) are threadedly engaged, when the clamping force on the workpiece is greater than the elastic force that the spring gives to the ratchet plate (5), the planar ratchet tooth A (41) and the planar ratchet tooth B (51) disengage, thereby controlling the clamping force applied to the workpiece.

[0019] The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
