[0034] See also Figures 3 to 5 The fixing portion 11 and the extending portion 12 of the fixing plate 1 are integrally formed. The fixing portion 11 is arranged in a circular structure. There are three extending portions 12 arranged around the fixing portion 11 and they are evenly distributed around the central axis of the fixing plate 1. There are six through holes 13 and they are evenly distributed around the central axis of the fixing plate 1. Correspondingly, there are also six step layers 14 and they correspond one to one with the through holes 13.

[0035] See also Figures 3 to 6 In the initial state, under the action of the elastic member 3, the extension 21 of the top rod 2 extends out of the top surface of the fixed plate 1 through the through hole 13. When installing the movable spring 4 on the top rod 2, first pass the positioning hole 41 on the movable spring 4 through the top of the extension 21 of the top rod 2, and then drip glue into the positioning hole 41 to achieve bonding between the movable spring 4 and the top rod 2. After the bonding is completed, the fixed plate 1, the top rod 2, the elastic member 3 and the movable spring 4 constitute a partial structure of the mechanical switch trigger assembly, and the formed product can be assembled with other parts to form a complete mechanical switch trigger assembly.

[0036] In one or more embodiments, the elastic member 3 is a spring or elastic steel.

[0037] In one or more embodiments, a mounting hole 15 is formed through the fixing plate 1. The mounting hole 15 is used to assemble the product formed by the fixing plate 1, the top rod 2, the elastic member 3 and the movable spring 4 on other structures, thereby forming a complete mechanical switch trigger assembly.

[0038] In addition, see Figure 1 , Figure 2The utility model also provides a dispensing fixture, which has a mechanical switch trigger component in any of the above-mentioned embodiments, and the dispensing fixture also includes: a dispensing table 5, on which an assembly portion 51 is formed for the fixing plate 1 to be placed and installed, and a countersunk hole 52 is formed on the assembly portion 51 for the ejector rod 2 and the elastic member 3 to enter and corresponding to the through hole 13; a clamping structure 6, which is arranged on the dispensing table 5, and the clamping structure 6 has at least one, and the clamping structure 6 is used to press the fixing plate 1 on the dispensing table 5; the clamping structure 6 is a quick clamp.

[0039] See also Figure 2 Six countersunk holes 52 are formed on the upper surface of the assembly portion 51 of the dispensing table 5. The six countersunk holes 52 are evenly distributed about the central axis of the dispensing table 5. The six countersunk holes 52 on the dispensing table 5 correspond one to one with the six through holes 13 opened on the fixing plate 1. The countersunk holes 52 are used to pre-place the ejector rod 2 and the elastic member 3, so that the staff can place the ejector rod 2 and the elastic member 3 on the dispensing table 5 in the through holes 13 of the fixing plate 1, which has a certain convenience.

[0040] See also Figure 2 The clamping structures 6 generally have two and are evenly distributed on the dispensing platform 5, so that the clamping structures 6 can fully press the fixing plate 1 on the dispensing platform 5. In other possible implementations, the number of the clamping structures 6 can also be three, and there is no specific limitation. In other possible implementations, the clamping structure 6 can also be a driving cylinder.

[0041] When assembling the mechanical switch trigger assembly, first loosen the quick clamp, then put the push rod 2 into the countersunk hole 52, the expanded portion 22 of the push rod 2 is located at the bottom of the countersunk hole 52, the extended portion 21 of the push rod 2 extends out of the countersunk hole 52, and the elastic member 3 is sleeved on the push rod 2. Then, place the fixed plate 1 on the assembly portion 51 of the dispensing table 5, so that the extended portion 21 of the push rod 2 extends out of the through hole 13 of the fixed plate 1, and the elastic member 3 is confined in the stepped layer 14. Use the quick clamp to press the fixed plate 1 on the dispensing table 5, and then place the movable spring 4. On the fixing plate 1, the top end of the extending portion 21 of the push rod 2 is passed through the positioning hole 41 of the moving spring 4, and finally the positioning hole 41 of the moving spring 4 is coated with ultraviolet solid glue, and the ultraviolet light is irradiated to solidify the solid glue. In this way, multiple moving springs 4 can be fixed at one time, while the fixing accuracy of the moving spring 4 is improved, the accuracy of product production is improved, and it is practical; after the fixing of the moving spring 4 is completed, the quick clamp is released and the fixing plate 1 is removed, which has the characteristics of convenient operation and simple structure.

[0042] In one or more embodiments, a side portion of the dispensing station 5 is formed with an avoidance groove 53, and the avoidance groove 53 is used to accommodate the extension portion 12 of the fixing plate 1. Figure 2The avoidance groove 53 is matched with the extension portion 12. When the fixed plate 1 is placed on the dispensing table 5, the extension portion 12 of the fixed plate 1 is located in the avoidance groove 53. Through this arrangement, the fixed plate 1 can be prevented from shifting relative to the dispensing table 5, thereby improving the installation quality of the movable spring 4.

[0043] In one or more embodiments, a bayonet gasket 7 is detachably mounted on the surface of the fixing plate 1 . The bayonet gasket 7 has a forked portion 71 and a handle portion 72 . The forked portion 71 is formed with a groove 73 for the extension portion 21 of the ejector rod 2 to enter.

[0044] See also Figure 1 When the bayonet gasket 7 is in use, it is necessary to place the bayonet gasket 7 between the movable spring 4 and the fixed plate 1, and make the protruding portion 21 of the push rod 2 located in the groove 73 of the forked portion 71 of the bayonet gasket 7, so that the bayonet gasket 7 can provide relatively stable support for the movable spring 4; the handle portion 72 of the bayonet gasket 7 can facilitate the staff to take the bayonet gasket 7.

[0045] In one or more embodiments, the clamping structures 6 have three groups and are evenly distributed around the central axis of the dispensing station 5 .
