Detailed Description

In order to facilitate a better understanding of the invention, the invention is further illustrated by the following examples in conjunction with the accompanying drawings.

As shown in fig. 1-3. In this embodiment, the chain riveting hammer includes handle 1, tup 2, sets up the holding direction chamber in the tup, locates the nail knocking mechanism in advance of tup through corresponding holding direction chamber, firing mechanism, chain riveting transport bin 14 to and automatic nail feeding device etc..

The pre-nailing and knocking mechanism comprises an energy storage spring 8 arranged in an energy storage containing guide cavity 7, an expander 4 arranged in an expansion containing guide cavity 3, an impact body 6 arranged on one side, corresponding to the expansion containing guide cavity 3, of an impact containing guide cavity 5, a knocking body 9 arranged between the energy storage spring and the expander and the like.

One end of the energy storage spring is connected with the wall surface of one end of the energy storage containing guide cavity in a propping mode, and the other end of the energy storage spring and the knocking body 9 can be fixedly connected. The spreader 4 is formed of two spreading arms 4a whose opposite ends are connected to each other by a hinge member such as a pin. The free ends of the two expansion arms 4a are provided with rollers or bearing rollers. The free end of one expansion arm of the expander is in rolling type abutting joint with the side wall surface of the expansion accommodating guide cavity and/or the lower wall surface of the impact body, and the free end of the other expansion arm is in rolling type abutting joint with the corresponding corner of the expansion accommodating guide cavity.

The diameter-expanding impact head 6a of the impact body 6 extends and protrudes out of the hammer head, and the impact accommodating guide cavity is provided with a diameter-expanding accommodating part 5a which is matched with the diameter-expanding impact head 6a of the impact body. One end of the striking body close to the inner side of the cavity is in contact connection with the hinged ends of the two expansion arms.

The chain riveting conveying bin 14 is arranged between the hammering end of the hammer head and the handle through a loading and unloading mechanism, the loading and unloading mechanism comprises a protruding part arranged on the upper part of one end, close to the handle, of the chain riveting conveying bin 14, a loading and unloading switch 18 arranged in a guide blind hole 17 of the handle and corresponding to the lower part of the protruding part of the chain riveting conveying bin 14, and a top spring 19 arranged in the guide blind hole and connected between the handle and the loading and unloading switch. The bottom wall of one end, close to the hammer head, of the chain riveting conveying bin is provided with a nail output hole 15 corresponding to the output end of the chain riveting conveying bin. The nail-discharging conveying bin is clamped between the handle and the hammer head by the loading and unloading switch 18.

The trigger mechanism comprises a guide hole 10 arranged on a handle, a trigger rod 12 arranged in the guide hole through a guide frame, a reset spring 11 sleeved on the trigger rod and connected between the trigger rod and the guide frame or the handle, and a sliding trigger switch 21, wherein the sliding trigger switch 21 is movably connected with the trigger rod through a pull rod or a pull wire. The trigger switch is arranged on the handle through a guide chute 20 on the handle.

The relative both sides of corresponding one end of handle 1 are equipped with the protrusion installation centre gripping arm, and the relative both sides of tup are equipped with the connecting groove who corresponds with this protrusion installation centre gripping arm, and handle 1 is through the both sides protrusion arm lock centre gripping formula riveting fixation, welded fastening or screw fixed connection in tup that its tip set up. The handle can be composed of a connecting arm made of metal materials and connected with the hammer head and a hand-held arm made of wood.

The energy storage accommodating guide cavity 7 is provided with a knocking body stroke opening 7a, one end of the knocking body 9 extends out of the knocking body stroke opening 7a of the energy storage accommodating guide cavity 7, and mutually opposite end faces of the knocking body 9 and the firing rod are provided with mutually matched inclined end faces.

The automatic nail feeding device comprises a magnet 13 corresponding to the nail strip conveying bin, and the magnet 13 is embedded on the hammer head.

When the nail discharging hammer works, nails are loaded into the nail discharging conveying bin, and the nail discharging conveying bin is loaded into the nail discharging hammer by the aid of the sliding assembling and disassembling switch. The handle is held by hand to expand the impact body of the hammer head to impact any hard object, the impact body instantly pushes the expander to expand and elongate the two expansion arms to compress the energy storage spring, and the impact body moves upwards along with the energy storage spring to pass through the firing rod and is clamped at a corresponding position by the firing rod. The knocking body and the nail are separated by a certain distance. Under this kind of state, as long as with the chain riveting carry the storehouse lean on foremost nail aim at by the nail object treat the nail position, the slidingtype trigger switch that slides again will fire the pole and roll back, the firing pole breaks away from and beats the body, the bulge of beating the body beats a corresponding nail in the chain riveting transport storehouse fast under the expansion effect of energy storage spring, with its through delivery outlet jet-out end just in advance on by the nail object, will be in advance with the tup nail on corresponding object in advance at last, accomplish the nailing of object. After a nail is driven out, the nail behind the nail can be automatically moved forwards by being attracted and pulled by the magnet. The firing rod automatically resets when the sliding type firing switch is loosened.

In another embodiment, as shown in FIG. 4. The free end surface of the expansion arm can be arranged to be a circular arc end surface. The part of the knocking body corresponding to the corresponding expansion arm is provided with an anti-skid limit boss 9 a. The expansion stroke and the expansion force of the expander can be exerted to the maximum extent, and the transmission loss is reduced. The impact body is a plunger type corresponding to the columnar impact containing guide cavity. The automatic nail feeding device comprises a movable nail pushing plate which is arranged in the chain riveting conveying bin and corresponds to nails, and a pressure spring which is connected between the nail pushing plate and one end, far away from the output hole, of the chain riveting conveying bin. The rest of the structure and the corresponding operation mode of the present example can be similar to the above-mentioned implementation.

The accommodating guide cavity can be manufactured by milling or molded by a casting mold, or a through hole can be formed firstly, and then the corresponding end surface of the handle or a plugging block plugs the position of a gap which needs to be sealed. The excess gap of the expanded receiving guide chamber as in fig. 4 can be sealed by a sealing block 24 with a protrusion 23 at its lower end, inserted into a corresponding recess of the hammer head through its protrusion 23, and fixed by glue.
