Referring to fig. 1 and 2, the valve core spring clamp 110 includes a connection column 111, and a first support plate 112 and a second support plate 113 movably connected to the connection column 111, wherein a spring 300 on the valve core 200 is clamped between the first support plate 112 and the second support plate 113, and first through holes 114 for the valve core 200 to pass through are formed in the first support plate 112 and the second support plate 113.
The first through hole 114 has a hole diameter greater than or equal to the outer diameter of the spool 200 and smaller than the outer diameter of the spring 300. Thus, the spring 300 can be held between the first support plate 112 and the second support plate 113 without passing through the first through hole 114.
Referring to fig. 3, preferably, the first through hole 114 is a stepped hole, the first through hole 114 includes a first hole section 1141 and a second hole section 1142, the first hole sections 1141 of the two first through holes 114 are close to each other, the second hole sections 1142 of the two first through holes 114 are far from each other, the hole diameter of the first hole section 1141 is greater than or equal to the outer diameter of the spring 300, and the hole diameter of the second hole section 1142 is greater than or equal to the outer diameter of the valve core 200 and smaller than the outer diameter of the spring 300. In this way, the spring 300 can be inserted into the first hole section 1141 and not pass through the second hole section 1142, and the positioning of the spring 300 can be stabilized.
The form of the connecting column 111 has many options as long as the first support plate 112 and the second support plate 113 can be connected into a whole and the distance between the first support plate 112 and the second support plate 113 can be adjusted.
In this embodiment, the connection column 111 includes a screw 1111 and a nut 1112, the first support plate 112 and the second support plate 113 have a mounting through hole 1143, the screw 1111 penetrates the mounting through hole 1143, and the nut 1112 is disposed on the screw 1111 and limits the first support plate 112 and the second support plate 113 to the screw 1111. Thus, the connecting column 111 has simple structure, easy assembly and disassembly, and low cost, and is very convenient for adjusting the distance between the first supporting plate 112 and the second supporting plate 113 to compress the spring 300.
The number of the connecting columns 111 is at least two, so that the first supporting plate 112 and the second supporting plate 113 can be uniformly stressed in the process of compressing the spring 300. In this embodiment, the number of the connection posts 111 is four, and the four connection posts 111 are uniformly arranged at the periphery of the first through hole 114 at intervals.
