As shown in fig. 1 and 2, the capillary tube bundle includes: a first clip 100, a second clip 200, a first molding part 300, and a second molding part 400. The first molding part 300 is detachably disposed on the first chuck 100; the second molding part 400 is detachably provided to the second chuck 200. The first molding part 300 is disposed opposite to the second molding part 400; the first molding part 300 has a first relief groove, and the second molding part 400 has a second relief groove 410. The middle section of the first abdicating groove and the corresponding middle section 411 of the second abdicating groove are inclined towards the first chuck 100 or the second chuck 200 and have the same inclination. When the first forming portion 300 and the second forming portion 400 are pressed, as shown in fig. 2, the first and second yielding grooves 410 are aligned to form the clamping cavity 10.
It can be seen that the middle section of the first and second yielding slots 411 are both inclined towards the same direction, so that the clamping cavity 10 forms a bent clamping cavity 10. The bent clamping cavity 10 extrudes the capillary tube under the action of external force so as to change the shape of the capillary tube into a bent shape, thereby solving the technical problem of accurately determining the length of the capillary tube assembled into the dry filter.
The first molding part 300 is detachably disposed on the first chuck 100, the second molding part 400 is detachably disposed on the second chuck 200, and the first molding part 300 and the second molding part 400 are replaceable, thereby realizing multi-purpose pliers.
In some embodiments, as shown in fig. 2, the first chuck 100 is provided with a first positioning groove (not shown), and the first forming portion 300 and the back end of the first receding groove are provided in the first positioning groove. The second chuck 200 is provided with a second positioning groove 210, and the back ends of the second forming portion 400 and the second abdicating groove 410 are arranged in the second positioning groove 210. In the present embodiment, the shapes of the first and second positioning grooves 210 are merely exemplary and are not particularly limited, and may be, for example, a square, a cylinder, or an irregular shape. The first seating groove serves to determine the installation position of the first molding part 300 in the first cartridge 100, and the second seating groove 210 serves to determine the installation position of the second molding part 400 in the second cartridge 200, so as to facilitate the installation of the first and second molding parts 300 and 400 and the precise alignment of the first and second relief grooves 410.
Figure 3 is a schematic diagram of a capillary clamp according to one embodiment provided herein, which in some embodiments further includes a first clamping arm 500, a second clamping arm 600, and a retainer pin 700. The first clamping arm 500 extends from the first cartridge 100 and has a first through hole. The second clamping arm 600 extends from the second chuck 200 to intersect the first clamping arm 500; and a second through hole arranged coaxially with the first through hole is arranged at the intersection. The fixing pin 700 penetrates the first and second through holes to hinge the first and second clamp arms 500 and 600. An extension line of the first clamping arm 500 is perpendicular to an extension line of the first abdicating groove; an extension line of the second clamping arm 600 is perpendicular to an extension line of the second abdicating groove 410. First arm lock 500 and second arm lock 600 all are equipped with anti-skidding sheath.
In this embodiment, a portion of the first and second clamp arms 500 and 600 is overlapped, and the fixing pin 700 connects the first and second clamp arms 500 and 600 in a hinged manner. When an upward force is applied to the first clip arm 500, the direction of the force is changed by the hinge structure of the fixing pin 700, and the first cartridge 100 applies a downward force to the first molding part 300. Similarly, the second clip arm 600 applies an upward force to the second molding part 400 through the second clip 200, and at this time, the first molding part 300 and the second molding part 400 are pressed to form a clip cavity (as shown in fig. 2), and pressure is applied to the capillary tube in the clip cavity, so that the capillary tube is molded into a predetermined shape. When a downward force is applied to the first clamping arm 500 and an upward force is applied to the second clamping arm 600, the first clamping portion and the second clamping portion are separated, and the capillary is taken out or placed, thereby completing the whole capillary deformation operation. It is obvious that the manner in which this embodiment is implemented is not the only one. The capillary forceps use the fixing pin 700 as a fulcrum, apply acting force to the first fixing part and the second fixing part in a lever mode, are labor-saving, light and easy to carry.
The first and second shield sleeves 510 and 610 prevent slipping during the operation of the first and second clamp arms 500 and 600, and facilitate the operation of the first and second clamp arms 500 and 600.
