Moreover, a first feature being “above”, “above”, and “above” a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being “below”, “below”, and “below” a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0036] like Figure 1-7 As shown, a novel nail shooter provided in this embodiment includes: a jacket component and a firing component arranged in the jacket component, and the jacket component includes a sliding-fitting movable component and a fixed component.

[0037] The above-mentioned movable assembly comprises a silencer sleeve 6, a connecting sleeve 7 threadedly connected to the silencer sleeve 6, and a heat insulating sleeve 5 is arranged on the outer periphery of the silencer sleeve 6. The silencer sleeve 6 and the heat insulating sleeve 5 play a dual silencing role.

[0038] The fixing assembly comprises a main sleeve 11, an adapter sleeve 12 and a connecting handle 13 which are threadedly connected in sequence. Specifically, the main sleeve 11 is slidably fitted on the outer periphery of the connecting sleeve 7. A sheath 14 is provided on the outer periphery of the adapter sleeve 12, and the sheath 14 is sandwiched between the main sleeve 11 and the connecting handle 13.

[0039] The firing assembly includes a nail tube 1, a firing pin tube 2 that slides with the nail tube 1, a firing pin assembly 3 that slides with the firing pin tube 2, and a firing spring 4. The nail tube 1 is inserted into the inner circumference of the movable assembly, and a limiting structure is provided between the nail tube 1 and the movable assembly so that the nail tube 1 and the movable assembly are stopped in the axial direction. Specifically, the nail tube 1 is inserted into the inner circumference of the silencer sleeve 6, and one end of the nail tube 1 extends out of the silencer sleeve 6 and is threadedly connected with a dust cover 9, which abuts against the heat insulation sleeve 5 to limit the axial position of the heat insulation sleeve 5 to prevent the heat insulation sleeve 5 from falling off. The connecting handle 13 is sleeved on the outer circumference of the firing spring 4 and is compressed and abutted against the firing spring 4, and the firing spring 4 is compressed and abutted between the firing pin assembly 3 and the connecting handle 13.

[0040] In this embodiment, the above-mentioned limiting structure includes a retaining ring 101 protrudingly arranged on the outer periphery of the nail tube 1 and a gasket 102 sleeved on the outer periphery of the nail tube 1. The above-mentioned retaining ring 101 abuts against one end of the silencer sleeve 6, and a limiting groove is formed between the silencer sleeve 6 and the connecting sleeve 7. The outer edge of the gasket 102 is embedded in the limiting groove. With this limiting structure, the nail tube 1 can be effectively prevented from moving in the axial direction.

[0041] Furthermore, a limiting assembly is provided between the firing pin assembly 3 and the firing pin tube 2. The limiting assembly limits the freedom of the firing pin assembly 3 to move in the direction of the nail tube 1 so that the firing pin assembly 3 is kept in its initial position. When the firing pin assembly 3 is in its initial position, there is a certain firing distance between the firing pin assembly 3 and the nail tube 1. A firing portion 1301 cooperating with the limiting assembly is provided on the connecting handle 13. The firing portion 1301 is specifically a conical surface provided at one end of the connecting handle 13 facing the firing pin assembly 3. The firing portion 1301 contacts the limiting assembly to release the firing pin assembly 3, so that the firing pin assembly 3 can move in the direction of the nail tube 1 under the elastic force of the firing spring 4.

[0042] like Figure 7 As shown, in this embodiment, the above-mentioned limit assembly includes a limit sleeve 201 and a brake pin 301 sleeved on the outer periphery of the firing pin tube 2. The limit sleeve 201 is connected to the firing pin assembly 3 through a limit pin 302. A slide groove slidably matched with the limit pin 302 is provided on the firing pin tube 2. A brake hole slidably matched with the brake pin 301 is provided in the radial direction of the firing pin assembly 3. A brake spring 321 compressed and abutted with the brake pin 301 is provided in the brake hole. When the firing pin assembly 3 is in the initial position, the brake pin 301 extends out of the brake hole and abuts with one end of the firing pin tube 2 close to the firing spring 4. Specifically, a notch matched with the brake pin 301 is provided at the end of the firing pin tube 2. In addition, the outer periphery of the brake pin 301 abuts with the inner periphery of the limit sleeve 201 to prevent the brake pin 301 from jumping out of the brake hole when the brake spring 321 rebounds, thereby ensuring that the firing pin assembly can be maintained in the initial position when no external force is applied.

[0043] Specifically, a blocking portion 1102 is provided on the inner periphery of the fixing assembly, and the blocking portion 1102 is fixedly clamped between the main sleeve 11 and the adapter sleeve 12, and one end of the limiting sleeve 201 away from the firing spring 4 abuts against the blocking portion 1102. The blocking portion 1102 is specifically a gasket to effectively prevent the limiting sleeve 201 from moving in a direction away from the firing spring 4 without external force.

[0044] In this embodiment, a first reset member 8 is compressed and abutted between the firing pin tube 2 and the nail tube 1. The elastic coefficient of the first reset member 8 is greater than the elastic coefficient of the firing spring 4. The first reset member 8 is a compression spring sleeved on the outer periphery of the firing pin tube 2. The above-mentioned connecting sleeve 7 is slidably inserted between the firing pin tube 2 and the main sleeve 11, and a second reset member 10 is compressed and abutted between the connecting sleeve 7 and the above-mentioned blocking portion 1102. The second reset member 10 is a compression spring sleeved on the outer periphery of the firing pin tube 2. The design of the first reset member 8 and the second reset member 10 can respectively reset the nail tube 2 and the firing pin assembly 3 after the nail shooting is completed, so as to prepare for the next nail shooting.

[0045] Furthermore, a first step surface 701 is provided on the inner periphery of the connecting sleeve 7, and a second step surface 202 is provided on the outer periphery of the firing pin tube 2. The cooperation between the first step surface 701 and the second step surface 202 not only limits the maximum extension position of the firing pin tube 2 relative to the connecting sleeve 7, but also prevents the movable component from slipping.

[0046] When in use, a nail is placed in the nail tube 1, the connecting handle 13 in the fixing assembly is held, the nail tube mouth is aligned with the object to be fixed, and the connecting handle 13 is pushed. At this time, the connecting handle 13 drives the connecting sleeve 12 and the main sleeve 11 to slide synchronously in the direction of the nail tube 1. In this process, the second reset member 10 is compressed and stored, and the blocking portion 1102 sandwiched between the main sleeve 11 and the connecting sleeve 12 slides synchronously, reserving space for the subsequent movement of the limiting sleeve 201 and the firing pin assembly 3. In addition, during the pushing process of the connecting handle 13, the firing spring 4 is compressed and stored, and applies elastic force to the firing pin assembly 3. The firing pin assembly 3 has a tendency to move in the direction of the nail tube 1 under the action of the elastic force. Since the brake pin 301 abuts against the end of the firing pin tube 2, the firing pin tube 2 also has a tendency to move in the direction of the nail tube 1 under the action of the firing spring 4. However, there is a first reset member 8 between the firing pin tube 2 and the nail tube 1, and the first reset member 8 applies a reverse elastic force to the firing pin tube 2, and the elastic coefficient of the first reset member 8 is greater than the elastic coefficient of the firing spring 4, so that the force applied by the firing spring 4 to the firing pin tube 2 is less than the force applied by the first reset member 8 to the firing pin tube 2, so that the distance between the connecting handle 13 and the firing pin assembly 2 is gradually reduced until the firing part 1301 contacts the brake pin 301, and the brake pin 301 is forced to retract after contacting the firing part 1301, so that the brake pin 301 is separated from the end of the firing pin tube 2. At this time, the firing pin assembly 3 that loses the restraint of the firing pin tube 2 can be ejected at a uniform speed in the direction of the nail tube 1 under the elastic force of the firing spring 4, thereby realizing the nail shooting action. The firing pin assembly 3 is shot into the nail tube 1, hits the propellant at the head of the nail, and the propellant pushes the nail into the object to be fixed, completing the nail shooting. Loosen the rear connection handle 13, and under the combined force of the firing spring 4, the first reset member 8 and the second reset member 10, the firing pin assembly 3, the fixed assembly and the firing pin tube 2 are reset. At the same time, the brake pin 301 returns to its original position under the action of the brake spring 321, so that the brake pin 301 is again in contact with the end of the firing pin tube 2 and the inner wall of the limit sleeve 201. Finally, hold the heat insulation sleeve 5 and push it toward the fixed assembly, driving the nail tube 1 to move toward the firing pin tube 2, so that the nail plastic shell remaining in the nail tube 1 is pushed out by the firing pin tube 2, loosen the heat insulation sleeve 5, and return the first reset member 8 and the second reset member 10 to prepare for the next nail shooting.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model, and they should all be included in the scope of the claims and specification of the utility model.
