In this way, the firing state of the nail gun can be controlled by using a simple locking block structure, and the switching operation method is very simple and can be completed by turning the locking block with one hand, thereby increasing the work efficiency of the user.

Description

Nailer trigger toggle switch

【Technical field】

The utility model relates to a trigger switching switch for a nailing gun, in particular to a trigger switch which is provided with a locking block at one end of the nailing gun trigger, by adjusting the locking block to produce different firing states of sequential firing and continuous firing. switch.

【Background technique】

Small electric tools have gradually replaced traditional human tools due to their advantages of easy portability, stable power supply, and easy operation and use, and have become indispensable tools for various projects such as construction, civil engineering, and decoration. The technology is mature, and various more humanized power tools are coming to the market one after another, so that consumers have more diverse choices.

Please refer to Fig. 1 to Fig. 4, when this kind of existing trigger switch is switched, it needs to apply force to press the pressing end 91 on one side of the trigger 90, so that the rotating end 92 is exposed on the other side, so that it can be pulled. Rotate the rotating end 92, and move the trigger piece 93 up or down with the eccentric shaft 920 on the rotating end 92, to determine the nail on the rear side of the trigger 90 touched by the first trigger part 930 or the second trigger part 931 of the trigger piece 93 Gun firing switch (not shown), the first triggering part 930 is closer to the firing switch of the nail gun, while the second triggering part 931 is farther away from the firing switch of the nail gun, so it can be used to control the sequential firing of the nail gun or batter.

But this kind of existing nail gun trigger switch has the following disadvantages:

1. The existing trigger switching switch requires one hand to press the pressing end, and then use the other hand to turn the rotating end, so that the switching between sequential firing and continuous firing can be performed, and both hands are required to switch the switch Switching, so the user must first place the nail gun on the table or floor, otherwise it will be difficult to implement.

2. The structure of the existing trigger switch is very complicated, and most of its components are small cylindrical bodies, which is not only not conducive to assembly, but also easy to drop and lose, which will seriously affect the production speed and cost, and cause a burden on users.

【Detailed ways】

The utility model relates to a trigger switching switch of a nailing gun. Please refer to FIG. 5 and FIG. , the nail gun body 1 has a safety switch 10 and a firing switch 11; the front end of the safety switch 10 is set at the nail outlet of the nail gun body 1, and the rear end is set at the preset position of the trigger 20, when the front end of the safety switch 10 is set When pressed, the rear end of the safety switch 10 will be pushed backward; the trigger switch 11 is set behind the preset position of the trigger 20, and when the trigger switch 11 is lightly touched, the nail gun body 1 will perform a continuous firing action. That is, continuous strikes; and if the firing switch 11 is fully pressed, the nail gun body 1 will perform a nailing action, that is, sequential firing.

The trigger 20 includes a pressing plate 21, a trigger piece 22, a blocking block 23 and a shaft 24, wherein:

The pressing plate 21 is generally a "ㄈ"-shaped cover body, and the upper end of the pressing plate 21 has a pivot hole 210, which can cooperate with a pivot piece 30 and a pivot sleeve 31 to pivot the trigger 20. It is provided on the nail gun body 1 ; the middle end of the trigger 20 is provided with a perforation 211 , and the perforation 211 cooperates with the shaft 24 to pivotally set the trigger piece 22 and the blocking block 23 inside the pressing lever 21 .

The lower end of the trigger piece 22 is provided with a set end 220, the set end 220 is slightly in the shape of "ㄈ", and the locking block 23 can be accommodated therein, and pivotally arranged on the inner side of the pressing plate 21; the trigger piece 22 A trigger end 221 protruding backward is provided at an appropriate place in the middle section, and the trigger end 221 is used to trigger the firing switch 11 .

A through hole 230 is pierced in the side of the locking block 23, and the locking block 23 is pivoted on the pressing plate 21 by using the through hole 230; a locking end 231 is provided on the locking block 23, and the locking end 231 protrudes more than the rest of the blocking block 23 and has a blocking effect.

The completed state of the switch structure combination of the trigger 20 of the nail gun body 1 of the present utility model is shown in FIG. When the front end of the safety switch 10 is pressed, the rear end of the safety switch 10 will touch the trigger piece 22 of the trigger 20, so that when the trigger 20 is pulled, the trigger end 221 of the trigger piece 22 of the trigger 20 can touch the firing switch 11.

When the utility model is in use, please refer to Fig. 7 to Fig. 12, when the snapping end 231 of the trigger 20 snapping block 23 faces the lower end of the trigger 20 (as shown in Fig. 7 ), it is in the sequential firing state; when the nail gun The front end of the safety switch 10 of the main body 1 is pressed, and the rear end of the safety switch 10 will touch the trigger piece 22, so that the trigger piece 22 is displaced to the rear side of the trigger 20 for a short distance (as shown in FIG. 8 ); the trigger 20 is pulled. , because the locking end 231 of the locking block 23 faces downward, it will not be restricted by the locking end 231 when the trigger 20 is pulled, but can be pressed into a deeper position. At this time, the triggering end 221 of the trigger piece 22 will be pressed to the rear of the trigger 20, and the firing switch 11 on the nail gun body 1 will interfere with each other because the trigger 20 can be buckled into a deeper position (as shown in Figure 9), so that the nail gun body 1 can achieve the purpose of nailing , which is sequential firing;

Conversely, if the locking block 23 on the trigger 20 rotates in reverse, let the locking end 231 of the locking block 23 be in a vertical state with the trigger 20, and choose to press the trigger 20 first (as shown in Figure 10 ), at this time, because the trigger The locking block 23 on the 20 is in a vertical state with the trigger 20. Therefore, the pressing stroke of the trigger 20 is shortened so that the locking end 231 of the locking block 23 can first abut against the nail gun body 1 (as shown in FIG. 11 ). Next, push the safety switch 10 at the front end of the nail gun body 1 against the work object, force the safety switch 10 to move backwards and push the trigger piece 22 back against the firing switch 11 (as shown in Figure 12), so as to achieve the purpose of nailing , keep pressing the trigger 20, and only move the safety switch 10 against the working object, so as to achieve the purpose of continuous nailing, that is, the so-called "combo".

To sum up, the utility model is mainly through the trigger 20 pivotally set a movable rotation adjustment blocking block 23, through the blocking block 23 to adjust to the trigger 20 horizontal pressing stroke is longer or vertical pressing stroke is shorter In the short state, there is an obvious difference between the deep and shallow pressing of the trigger 20, so as to achieve the effect of fast switching between "sequential firing" and "sequential firing" of the nail gun.
