[0009] Further, the height of the mounting groove is lower than the height of the V-shaped groove.

[0010] Further, the upper clamping plate is provided with a convex part two for being clamped into the mounting groove.

[0011] Furthermore, the width of the mounting groove is smaller than the width of the V-shaped groove.

[0012] Furthermore, the height of the elastic sleeve does not protrude beyond the height of the V-shaped groove.

[0013] Furthermore, a vertically arranged guide groove is provided on the clamping seat, the lower clamping plate is fixedly arranged at the lower end of the guide groove, and the upper clamping plate is slidably arranged in the guide groove and is located above the lower clamping plate.

[0016] Furthermore, there are two mounting grooves, and an elastic sleeve is provided in each mounting groove.

[0017] Compared with the existing technology, the present guide wire clamping structure can pre-thread the guide wire between the V-groove and the elastic sleeve, which plays a role in limiting the initial positioning position of the guide wire. At the same time, the second convex part fits with the V-groove, and the discharge end of the guide wire on the seat body is the lowest point of the V-groove. The guide wire tends to be in a straight line as a whole on the chuck seat, which reduces damage to the guide wire clamping end during the stretching process, ensures that the guide wire is in a consistent straight line state after being stretched and straightened between the two chuck seats, improves the accuracy of guide wire clamping, and drives the upper and lower splints to clamp together. The second convex part squeezes the elastic sleeve, driving the guide wire to move to the lowest point of the V-groove. When the part of the guide wire on the V-groove and the part of the mounting groove are staggered in height, stable clamping and positioning of the guide wire is achieved.

[0024] Embodiment 1, please refer to Figures 1 to 3 It is a guide wire clamping structure schematic diagram provided by the utility model. The guide wire clamping structure is applied to a guide wire tension testing machine. The guide wire clamping structure comprises a clamping seat 10, an upper clamping plate 20 and a lower clamping plate 30 arranged on the clamping seat 10, a clamping driver 50 for driving the upper clamping plate 20 and the lower clamping plate 30 to clamp, and a guide wire positioning assembly 40 arranged between the upper clamping plate 20 and the lower clamping plate 30. It is conceivable that the guide wire clamping structure further comprises other functional components and specific structures, such as electrical connection components, control components, mounting structures and the like, which are all known technologies for those skilled in the art, and therefore will not be described in detail here.

[0025] The guide wire is a long flexible silk structure. The two groups of clamping seats 10 clamp the end of the guide wire, and finally realize the guide wire tension test.

[0026] The clamping seat 10 serves as a mounting space for the upper clamping plate 20, the lower clamping plate 30 and the clamping driver 50. In this embodiment, the clamping seat 10 is in the form of a rectangular block structure, and the circumferential outer wall is in the form of a flat surface, which facilitates the installation and is compact and reliable in overall structure.

[0027] In this embodiment, the upper clamping plate 20 and the lower clamping plate 30 are vertically and spaced apart on one side of the clamping seat 10. Specifically, the clamping seat 10 is provided with a vertically arranged guide groove 11. The lower clamping plate 30 is fixedly arranged at the lower end of the guide groove 11. The upper clamping plate 20 is slidingly arranged in the guide groove 11 and above the lower clamping plate 30. The clamping driver 50 is arranged at the upper end of the clamping seat 10 and connected with the lower clamping plate 30. The lower clamping plate 30 serves as a fixed end to pre-position the structure of the guide wire. The single-driven upper clamping plate 20 is used to clamp, thereby reducing the relative clamping displacement distance of the guide wire. The clamping driver 50 comprises any one of a bolt, a cylinder and a motor. In this embodiment, a spring is arranged between the upper clamping plate 20 and the lower clamping plate 30. The clamping driver 50 adjusts the vertical position of the upper clamping plate 20 by means of manually rotating the bolt, so as to force the upper clamping plate 20 to move to one side of the lower clamping plate 30 to realize clamping.

[0028] The middle part of the lower clamping plate 30 is provided with a V-shaped groove 41 arranged along the length direction, the guide wire tends to be placed at the lowermost end of the V-shaped groove 41 by its own gravity, the bottom of the upper clamping plate 20 away from the clamping seat 10 is provided with a protruding part 21 matched with the V-shaped groove 41, the protruding part 21 is matched with the V-shaped groove 41, the lowest point of the V-shaped groove 41 is at the discharging end of the seat body, the guide wire tends to be in a straight line state on the clamping head seat as a whole, which reduces the damage to the clamping end of the guide wire during the stretching process, and ensures that the guide wire is in a consistent straight line state after being stretched and straightened between the two clamping head seats, thereby improving the accuracy of the guide wire clamping and discharging position.

[0029] The guide wire positioning assembly 40 includes a mounting groove 42 recessed in the middle part of the lower clamping plate 30 and communicated with the V-shaped groove 41, an elastic sleeve 43 arranged in the axial direction is embedded in the mounting groove 42, the upper end of the elastic sleeve 43 protrudes from the mounting groove 42, the guide wire can be previously arranged between the V-shaped groove 41 and the elastic sleeve 43 when the guide wire is placed on the lower clamping plate 30 and passes through the elastic sleeve 43, the elastic sleeve 43 limits the position of the guide wire on the lower clamping plate 30, so that the flexible guide wire tends to be located at the lowermost end of the V-shaped groove 41, thereby playing a role in limiting the initial positioning position of the guide wire.

[0030] Optimally, the height of the mounting groove 42 is lower than the height of the V-shaped groove 41, and the embedded installation ensures the installation reliability and consistent deformation direction of the elastic sleeve 43. The upper clamping plate 20 is provided with a protruding part 22 matched with the mounting groove 42, the protruding part 22 can accurately extrude the elastic sleeve 43 into the mounting groove 42, drive the clamping of the upper clamping plate 20 and the lower clamping plate 30, extrude the elastic sleeve 43 by the protruding part 22, and move the guide wire to the lowest point of the V-shaped groove 41, when the part of the guide wire on the V-shaped groove 41 and the part of the mounting groove 42 are staggered in height, the stable clamping and positioning of the guide wire is realized.

[0031] The width of the mounting groove 42 is smaller than the width of the V-shaped groove 41, and the height of the elastic sleeve 43 does not protrude from the height of the V-shaped groove 41. It can avoid that the excessive elastic sleeve 43 affects the close clamping of the upper clamping plate 20 and the lower clamping plate 30 during the deformation process.

[0032] In other embodiments, please refer to Figure 4 The clamping driver 50 can also be a torsional spring, the clamping driver 50 is arranged on one side of the clamping seat 10 and connected with the upper clamping plate 20 and the lower clamping plate 30, the upper clamping plate 20 and the lower clamping plate 30 have a clamping tendency by the elastic potential energy of the torsional spring.

[0033] In other embodiments, please refer to Figure 5 The mounting groove 42 has two, each mounting groove 42 is provided with an elastic sleeve 43, and the plurality of elastic sleeves 43 are corresponding to the number of staggered clamping points of the lower clamping plate 30, thereby improving the stability of the clamping of the end of the guide wire.

[0034] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art of the present application can make various modifications or supplements to the described specific embodiments or replace them with similar ways, but will not deviate from the spirit of the present application or exceed the scope defined by the appended claims.
