Example Embodiment
[0021] Example 1
[0022] See Figure 1~2 In the embodiment of the present invention, an anti-self-locking mechanism of a trigger switch includes a casing 1, a casing 5 and a trigger 4. The trigger 4 is installed between the casing 1 and the casing 5, and the casing 5 is movably installed with anti-self-locking The anti-self-locking device includes a limit slot in the casing 1 and a locking plate 3. The limit slot is opened in the casing 1, and the locking plate 3 is movably installed in the limit slot inside the casing 1. The locking plate 3 is It is limited in the limit slot in the casing 1, which can realize up and down movement, and control the movement of the trigger 4, the locking plate 3 and the casing 1 work together, and the control trigger 4 realizes the anti-self-locking function.
[0023] An anti-self-locking button 7 for controlling the anti-self-locking device is installed on the outer side of the housing 5, an anti-self-locking reset device connected to the trigger ...
Example Embodiment
[0027] Example 2
[0028] The shell of the anti-self-locking machine of trigger switch is prepared according to the following method:
[0029] 1) Weigh the raw materials in parts by weight: 1 part gallium, 1 part cerium, 1 part neodymium, 2 parts glass fiber, 3 parts niobium, 3 parts zirconium, 8 parts zinc, 10 parts graphite, 10 parts titanium, 30 parts silicon Parts, 80 parts of aluminum, 1000 parts of magnesium;
[0030] 2) Add glass fiber and graphite to acetone in sequence, stir at 100 revolutions / min for 6 hours, and then refrigerate at 4°C for 12 hours to obtain auxiliary materials; wherein the mass ratio of acetone to graphite is 2:1;
[0031] 3) Preheat gallium, cerium, neodymium, niobium, zirconium, zinc, titanium, silicon, aluminum and magnesium at 200°C for 1 hour;
[0032] 4) Use a crucible resistance furnace to melt the preheated magnesium, then add auxiliary materials, zinc, silicon and aluminum at 750℃, and stir the melt for 3min; continue to heat up to 780℃, add galliu...
Example Embodiment
[0034] Example 3
[0035] Comparative experiment 1: The process steps are the same as in Example 2, except that graphite and glass fiber are not added.
[0036] Comparative experiment 2: The process steps are the same as in Example 2, except that gallium, cerium, neodymium, niobium and zirconium are not added.
