Nail gun safety actuating device

The invention relates to a nail gun safety actuating device, which is configured to reduce the stress impact of the interlocking rod piece and the safety switch by the elastic action of the trigger spring and the safety switch of the interlocking rod piece through the top abutting object of the safety sliding sleeve. The accuracy of the triggering distance is increased, and at the same time, the safety strike of the nail gun is completed by the needle indicating function of the safety sliding sleeve.

Investigate that the current electric nail guns on the market mainly use the electric drive to cooperate with the mechanical actuating mechanism to generate the nailing force, so as to achieve the nailing action. Therefore, the actuating structure has been simplified, that is, when the linkage rod When the piece touches the working object to be stapled, the interlocking piece will synchronously trigger the safety switch, and the control circuit can obtain an electric control signal, and then actuate by the pressing unit, so that the nail piece can obtain an elastic force. The nail piece is then driven to strike the nail, thereby achieving the function of the nail member.

Please refer to the fifth and sixth figures, which is a schematic diagram of the operation of the conventional electric nail gun safety actuating device (80) in the nail gun casing (70). The safety actuating device (80) includes a linkage rod piece (81). The threaded rod (71) of the casing (70) extends to the front end of the nailing opening (72) of the casing (70). As a guide for the safety of the member to be nailed, a return spring (82) is disposed in the middle of the linkage rod (81), and is correspondingly received in the housing (70). Positioning, providing the elastic force of the interlocking rod piece (81) to restore the positioning after actuation, and the triggering piece (81) is provided with a triggering portion (83) toward the end of the safety switch (90), the touch The emitting portion (83) can relatively strike the actuating piece (91) of the safety switch (90), thereby transmitting a triggering telecommunication information for the subsequent mechanism to generate the force of the nailing, thereby achieving the purpose of the nailing of the nail gun.

However, the above-mentioned conventional nail gun safety actuating device actually has the following disadvantages:

1. Please refer to the sixth and eighth figures. The triggering part (83) of the interlocking lever piece (81) is made of plastic material, and the actuating piece (91) for elastically contacting the safety switch (90) is shown. Generally, the triangle frame shape with an opening is formed, and the trigger frame (84) of the plastic triggering portion (83) is prone to deformation or plasticized fracture at the corner due to long-term use, resulting in a linkage piece (81). The safety switch (90) or the early triggering doubt cannot be triggered accurately, causing the nail gun to cause a malfunction and causing a malfunction.

2. Please refer to the triggering part (83) of the triangular frame shape shown in the seventh figure, and the triggering frame (84) is obliquely slidably to touch the operating piece (91) of the safety switch (90). When the needle is to be nailed to the object of a thin height, the displacement distance of the interlocking rod piece (81) obliquely upward is too small, so that the trigger frame (84) of the triggering portion (83) cannot trigger the safety switch (90). Acting, resulting in the nail gun can not successfully achieve the purpose of nailing.

3. The conventional interlocking rod piece (81) is directly attached to the nailing member at the bottom end of the sheet body, and is used as a safety guide for the nail gun to be shot out, because the needle indicating end is lacking at the nail guiding end. The function, so the user can only be stapled according to the normal state, causing the nail to be stuck in an incorrect position, or the nail can not be pinched on the object, especially the cable clamp is the most easy. Causes damage to the wire and jeopardizes the safety of use.

4. Moreover, the triggering portion (83) of the conventional interlocking lever piece (81) directly contacts the actuating piece (91) of the safety switch (90) by the trigger frame (84), and when the nail is actuated, the nail gun The safety actuating device (80) will withstand the impact of the post-impact force. Therefore, the trigger frame (84) also has the concern of striking the actuating plate (91). The long-term use will inevitably burden the safety switch (90).

The main purpose of the nail gun safety actuating device of the present invention is to improve the shortcomings of the above structure. The main technology is that a safety sliding seat is arranged on the nail opening of the nail gun and the nail member, and the safety sliding seat is connected with a linkage rod. The linkage rod is further connected with a carrier and a trigger spring, so that the trigger spring of the linkage rod directly elastically presses the safety switch to improve the accuracy of the trigger distance, and at the same time, the safety is achieved. The needle indicating function of the sliding sleeve is used to improve the accuracy and safety of the nailing, thereby achieving the function of nailing the nail safely.

In order to achieve the above object, the present invention mainly comprises a plurality of assembly slots for the components disposed inside the nail gun body, and a nail opening is provided at the front end of the nail gun body for a nail gun safety actuating device.

According to the telecommunication function, the following information is transmitted to the subsequent mechanism to obtain the nailing function; accordingly, the safety sliding sleeve is disposed in the outer edge chute of the nailing body of the nail gun body through the safety sliding sleeve, the bottom edge Actuating as a contact end of the object, and actuating the linkage rod with the abutting block, so that the The interlocking rod piece is actuated in the nailing slide of the nail gun body, and the triggering spring directly elastically presses the top to trigger the activation of the safety switch to form a telecommunication information transmission for triggering the nailing, so that the subsequent mechanism generates the nailing force. At the same time, the function of the safety pin of the nail gun is completed by the needle indicating function of the safety sliding sleeve.

Therefore, in accordance with the technical means of the present invention, a brief description of the functions obtainable by the present invention is as follows:

1. The trigger spring provided by the linkage rod and the return spring for returning the positioning, after the impact force of the nail gun to generate the impact, the two springs have the function of absorbing the impact force, avoiding the interlocking rod and the safety switch. Direct impact increases the life of the safety switch.

2. The trigger spring disposed at the top end of the linkage rod is vertically driven with the actuation piece of the safety switch. Therefore, when the safety sleeve is applied to the object with a relatively shallow thickness, the linkage rod is short. The stroke is upward, and the force of the stroke can be pressed against the trigger spring, and at the same time, the actuating piece of the safety switch is actuated to trigger the transmission of the telecommunication information to achieve the nailing function, so as not to cause the nail to malfunction.

3. The cover of the safety sliding sleeve is provided with a plurality of needle indicating marks, and the user can know in advance the nailing position of the nail to be stapled through the lateral needle marking and the forward needle marking. At the same time, the notch can also be used as a pinch clamp for the stability and accuracy of different wires.
