Problems solved by technology
[0007] 1. Since there must be an additional cylinder seat in the air chamber, and an appropriate space must be formed between the outer diameter of the cylinder seat and the inner diameter of the air chamber, and the inner wall of the cylinder seat can be used for the piston group to move up and down, therefore, it will cause the piston group to move The cross-sectional area is limited, and the momentum that the piston group can form is considerably limited
[0008] 2. As mentioned above, since there are many kinds of nail guns and their sizes are different, in order to make the nail gun applicable to larger nails, it is often necessary to increase the overall volume of the nail gun so that the air chamber And the cylinder seat is also relatively increased; in this way, it will not only increase the material consumables required for the gun body, but also greatly increase the total weight, and make the operation appear unstable or difficult to control , resulting in accidental injury
[0009] 3. As mentioned above, due to its many and complex components, it will make its assembly process cumbersome and inconvenient, and its production speed will be limited, thereby reducing its production output and increasing production costs

The present invention relates to a power actuated nail-setting gun without cylinder. It includes gun body, piston group, pressure seat and upper cover seat. The described gun body can be respectively formed into valve chamber, main air channel and exhausting hole. Said valve chamber is respectively communicated with main air channel and exhausting hole, and the upper cover seat is mounted in the upper portion of valve chamber of gun body, and the piston group and pressure seat are positioned between the upper cover seat and valve chamber of gun body. Said invention also provides the concrete structure of the above-mentioned every component. Its structure is simple, and can be conveniently assembled.
Description
technical field [0001] The invention relates to a nailing gun, in particular to a nailing gun without an additional cylinder. Background technique [0002] The structure of existing nail gun, as shown in Figure 1, Figure 2, image 3 , Figure 4 As shown, the upper cover 2 is mainly installed on the air chamber 26 of the gun body 1 through the fixing parts, and the upper cover 2 and the air chamber 26 of the gun body 1 are provided with a spring 24, a top pressure seat 4, and a cylinder seat cover 23 in sequence. And the cylinder seat 27, the piston group 3 can move back and forth on the inner wall of the hollow cylinder seat 27; the appropriate position in the gun body 1 is respectively provided with the air chamber 26, the main air passage 11, the accommodation chamber 14, the lower through hole 111 and the upper The through hole 110, wherein the main air channel 11 communicates with the air chamber 26 and the accommodating chamber 14 respectively, and the accommodating ch...
