Description of the new type: [Technical field to which the new type belongs] This creation is a ratchet structure, especially a ratchet structure of a chain nail gun. [Prior art] Generally, a chain nail gun can be seen on the market. The user must apply force to push the nail pushing device to complete the nailing operation. However, most users will experience hand tremor when applying force. This hand shake situation will cause the user to easily deviate the screw and the target during the nailing operation, and the user is also prone to aches and pains due to the long-term application of force after using the nail gun for a long time. . In view of the fact that the current chain nail gun is still in use, the creator has been engaged in many years of experience in the production and marketing of chain nail gun related products, and in view of the current problems with the chain nail gun, he thought about the improvement. Method: After many improvements and tests, a chain nail gun ratchet structure was finally created. [New content] For this reason, the main purpose of this creation is to provide a feature of using a ratchet wheel to perform forward and reverse rotations to achieve the purpose of changing the upper nail travel of a chain nail gun. In order to achieve the above purpose, I have created a chain nail gun ratchet structure, which can be pivoted in the nail pushing device of the nail gun and contains a ratchet set, which is provided with a ratchet 5 M268143 wheel at each end. The ratchet wheel is externally provided with a wheel pivoted to the axial direction thereof, and the outer periphery of the ratchet wheel includes a plurality of gear teeth, so that the buckle can be buckled to a part of the screw belt. The arc-shaped grooves allow the arc-shaped grooves located at the upper semicircle to tilt toward the other end of the gun body when rotating, so that the face with a larger inclination, that is, facing toward the body, forms an edge. A plurality of edges corresponding to the arc-shaped groove shape are formed on the driving side surface, and the card edge is formed at the abutting edge to form an abutting edge to drive a flange fixed on the outer surface of the wheel. At the end of the axial pivot, the inside of the accommodation and the outside of the two belts are pressed against each other by two butterfly type gaskets. However, the above description is only a description of the characteristics of this creation. Reviewers and professionals who read this manual are Can better understand the technical means of this creation and implement the contents of this manual, so the illustration of this creation is illustrated with the illustrations, but the following is only an example to explain this creation, and does not limit the creation in any form. Therefore, any modifications or changes made to this creation under the same creative spirit should be included in the protection of this creation. [Embodiment] Please refer to the second to fifth pictures. The structure can be pivoted in the nail pushing device (2) of the nail gun and includes a ratchet set (3). The ratchet set (3) is respectively provided with a ratchet at both ends ([to drive the card in one end of the ratchet rack on the tooth surface of the wheel, there should be a movable wheel state. Anyone can add according to the instructions, and it is any L circle. Chain belt housing 6 ^ 0) M268143 so that its upper peripheral edge is located at the height of the muzzle (8 5), and a ratchet wheel (3 1) is axially pivoted to the outside of the ratchet wheel (3 0), and the ratchet wheel (3 0) The outer periphery includes several gear teeth (3 0 0), which can make part of the screw belt (9 0) buckle, and the outer surface of the ratchet wheel (3 0) is connected with The ratchet wheel (30) is concentrically provided with a plurality of arc-shaped grooves (301), so that the ratchet wheel (30) is located in the arc-shaped groove (30) of the upper semicircle when it is rotated. 7 0) —end toward the gun body (80). The end is inclined, so that the end face with a larger inclination, that is, an edge (3 0 10) is formed in the direction of the gun body (80). In addition, the driving A plurality of card edges (3 1 0) corresponding to the shape of an arc-shaped groove (3 0 1) are formed on the inner surface of the wheel (3 1), and the card edges (3 1 0) are attached to the abutment edge (3 0 1 0) Edge (3 1 0 0), please cooperate with reference to the third figure, in order to make the driving wheel (3 1) turn clockwise to drive the ratchet wheel (3 0) to rotate in the same direction, the arc-shaped groove ( 3 0 1) One end of the ratchet wheel (3 0) is formed into a concave depression clockwise toward the other end, so when the abutment edge (3 1 0 0) abuts the abutment edge (3 0 1 0) At this time, the driving wheel (3 1) can drive the ratchet wheel (3 0) to rotate clockwise, and the screw belt can be driven a distance from bottom to top; otherwise, when the driving wheel (3 1) is counterclockwise When rotating in the direction, the card edge (3 1 0) will slide out of the arc-shaped groove (3 0 1) so that the driving wheel (3 1) 7 M268143 cannot drive the ratchet wheel (3 Ο) to rotate. In addition, the A flange (3 1 1) is fixed on the outer surface of the driving wheel (3 1). The flange (3 1 1) has an axially pivotable end section and can pass through the nail pushing device housing. (2) The arc-shaped chute (2 0) is placed on the first section (1 0 1) of the slide holder (1 0) embedded in the outer casing (1). The slide holder (1 0) The first paragraph (1 0 1) is a one-year-old The inclined section with one end low and the other high in the mouth direction, and the higher one is connected to a second section (102) without tilt. See also the fifth figure, in the nail pushing device housing (2) Two elastic bodies are respectively arranged between the two driving wheels (3 1), so that the driving wheels (3 1) can be pressed against the ratchet wheel (3 0) by the pressing force of the elastic body to ensure the card edge (3 1 0). ) Is normally inserted into the arc-shaped groove (3 0 1), and in the preferred embodiment of the present invention, the elastic system is an elastic butterfly pad (3 2). According to the design and configuration of the above components, it can be known that the pivotable final section of the flange passes through the arc-shaped chute (2 0) and is arranged at the first section (1 0 1) of the slide rail (1 0). ), Please refer to the second and fourth figures. When the nail pushing device housing (2) starts to slide in the direction of the gun body (80) and gradually press against the spring (4), the flange is Drive the gradual movement from the first section (1 0 1) of the slide rail (1 0) to the second section (1 0 2), when the flange moves from the lower end of the first section (1 0 1) to the higher end When the flange drives the driving wheel (3 M268143 1) to rotate at an angle, but because the arc groove (3 〇 1) has an inclined surface and has a clockwise edge (3 Ο 1 0) design So that when the driving wheel (3 1) rotates, the abutment edge (3 1 0 0) cannot abut the abutment edge (3 〇 1 0), so that the ratchet wheel (3 0) will not rotate accordingly. That is, there is no action of nailing; and when the spring (4) is compressed by the elastic restoring force, the housing (2) of the nail pushing device is pushed back in a direction different from the body (80), please Mate See Second As shown in the figure and the third figure, the flange gradually slides from the second section (1 0 2) of the sliding handle (1 0) to the first section (1 0 1). 0 1) When the higher end slides down to the lower end, the flange can drive the driving wheel (3 1) to rotate at an angle, and the curved groove (3 0 1) has an inclined surface and a smooth surface The design of the edge (3 0 1 0) in the clockwise direction allows the ratchet wheel (3 0) to be driven to rotate by an angle by the driving wheel (3 1) and makes the screw band embedded in the tooth (3 0 0) (9 0) Move the screw (9 5) up to the muzzle (8 5) to complete the nailing operation. After the nailing operation is completed, the user repeats the operation of the nail pushing device housing (2) mentioned in the previous paragraph. Slide the body (80) in the direction and press the power button at the same time, you can start the nail gun to make the screw (9 5) screw into the screw by the rotation of the transmission post (60). Therefore, when the user uses this creation with a chain nail gun, 9 M268143 because the nailing step is at the back of the restored state after the spring (4) is compressed, that is, the user did not attach the shell of the nail pushing device at that time. The body (2) exerts pressure, so when the screw is screwed on, the screw will not deflect due to the user's force. When the nail is used, the user can effortlessly apply it. Nail action can also increase the success rate and accuracy rate when screwing into a screw. In summary, the ratchet structure of the chain nail gun of this creation can not only effectively improve the shortcomings of the conventional chain nail gun, but also the main technical means of this creation have not been found in any relevant publications, which is in line with the application for new patents. For the essentials, apply in accordance with the law, and kindly ask Jun Bureau to grant permission for this creation patent.
