In the embodiment of the application, the clamping base fixing component comprises two support plates, at least one support plate is provided with a concave part, and when one support plate rotates to be abutted against the other support plate, the concave part between the two support plates forms an accommodating part. When the support plate is used, one support plate can rotate relative to the other support plate, and one side edge is used as an axis to relatively rotate. The two supporting plates are at least partially abutted, generally speaking, the two supporting plates are rotated to be parallel and partially abutted or jointed. The angle formed between the two support plates is 0 ° to 180 °, preferably 0 ° to 90 °. For example, one of the support plates has a recess and the other support plate does not have a recess; or, the two supporting plates can be provided with a concave part, when the two supporting plates rotate to abut against each other, the supporting plates abut against each other except the concave part, and the concave part is used as an accommodating part for accommodating the clamping base.

In one embodiment, as shown in FIG. 3, the clip base securing assembly 200 includes two support plates: a first support plate 210, and a second support plate 220 rotatably connected (e.g., hinged) to the first support plate 210. Both having a recess on opposite faces. First backup pad 210 and second backup pad 220 can be connected through the round pin axle between, and second backup pad 220 rotates for first backup pad 210, rotates to when butt with first backup pad 210 at second backup pad 220, and the depressed part between the two forms the portion of holding, can be used to place the clamping base, and the opening orientation of this portion of holding compresses tightly 100. In operation, the clip base (the leftmost structure in fig. 3) is placed on the first support plate 210, and then the second support plate 220 is rotated to abut against the first support plate 210, and at this time, the clip base is located in the accommodating portion by forming the accommodating portion between the first support plate 210 and the second support plate 220.

In one embodiment, the locking member 201 is used to lock the first support plate 210 and the second support plate 220, that is, when the first support plate 210 rotates to abut against the second support plate 220, the first support plate 210 and the second support plate 220 are locked to prevent the second support plate 220 from being separated, which results in the problem that the clip base cannot be fixed. For example, the locking member 201 includes two latches, and the two latches are respectively rotatably connected (e.g., hinged) to two ends of the first support plate 210, and the latches can rotate relative to the first support plate 210, that is, one latch is hinged to each end of the first support plate 210, and the latch can rotate relative to the first support plate 210. The structure will be described by taking the front view orientation of the first support plate 210 as an example. Please refer to fig. 3, that is, the second supporting plate 220 is hinged to the bottom of the first supporting plate 210, the top of the first supporting plate 210 is connected to the compressing portion 100 through the guide rail 300, and the two latches are respectively disposed at the left and right ends of the first supporting plate 210, when in use, the second supporting plate 220 hinged to the bottom is rotated upwards to abut against the first supporting plate 210, and then the latches at the left and right ends are rotated to be connected with the second supporting plate 220 in a clamping manner, so as to fix the first supporting plate 210 and the second supporting plate 220. The shape of the latch may refer to the structure of the hook, that is, by hooking the second supporting plate 220, to lock the two.

In a more specific embodiment, in order to further realize the quick positioning of the clip base and increase the stability of the fastening timing, the first support plate 210 and the second support plate 220 are both provided with a limiting groove 202, that is, the limiting groove 202 extending on the accommodating portion just matches with the convex edge on the clip, and can be used for limiting the clip base. The structure of clamping base is as shown in fig. 4, and clamping base 500 is the rectangle, and the jack that a plurality of can place the cathode tube is seted up at its top to two sides of clamping all are provided with a plurality of chimbs, and the chimb is the level setting with male cathode tube. When the clamping base is placed into the clamping base fixing assembly 200, the extended limiting groove 202 in the accommodating part can be just used for placing the convex edge on the clamping base, so that the clamping base is fixed in the clamping base fixing assembly 200, and the shaking of the clamping base cannot be caused when the clamping base is installed, and the installation effect is influenced.

In one embodiment, the pressing portion 100 is provided with an insertion hole for inserting a cathode tube on a surface facing the fixing component of the clip base, so that the pressing portion 100 can drive the cathode tube to move and be inserted into the clip base in the process of pressing the accommodating portion, and the assembly is completed. In a preferred embodiment, a magnetic member is disposed inside the insertion hole of the pressing portion 100 for absorbing the cathode tube, for example, a magnet is disposed to absorb the cathode tube, so as to prevent the cathode tube from being easily separated from the pressing portion 100 due to gravity during the movement of the cathode tube. Of course, in other embodiments, the cathode tube may be manually inserted into the clip base, and then the pressing portion is pressed to insert the cathode tube into the clip base.

In order to realize that the cathode tube can be just in time located in the installation position of the clamping base, the insertion hole position for putting in the cathode tube in the pressing portion 100 needs to be adjusted, the insertion hole position should correspond to the installation position on the clamping base, so that when the pressing portion 100 drives the cathode tube to press towards the direction of the clamping base, the cathode tube can be just in time inserted into the installation position, and most of the cathode tube can be inserted into the installation position by continuously pressing, because the aperture in the installation position is smaller, the diameter of the cathode tube is the same as or slightly smaller than that of the cathode tube, therefore, when the pressing portion 100 resets, the cathode tube still remains inside the clamping base due to the action of friction force, and is separated from the pressing portion 100 (the action of magnetic force between the cathode tube and the pressing portion 100 is smaller).

To sum up, in this application be used for clamping base negative pole fixed device forms the portion of holding through adopting two backup pads of relative rotation when the butt, can supply the clamping base to put into and fix, and carry out reciprocating motion in the top of clamping base through the portion that compresses tightly, with the realization with the purpose of the cathode tube impressed in the clamping base, whole process adopts the machine to carry out the centre gripping to the clamping base, fix and the cathode tube inserts, need not artifical clamping base of holding and artifical cathode tube that inserts, and be difficult to cause the slope when the cathode tube inserts, effectively provide the product percent of pass.
