Riveters are used in industry and house building. Two plates are commonly riveted together by such riveting tools. In the previous prior art, the head of the riveting tool is not adjustable. Either a T-type head or in-line head, relative to their handle, are provided (as shown in FIGS 1 and These are inconvenient to the workman having to choose either one to fit his work position. Working on a ceiling or floor may call for a T-type riveting tool, for example.

Both types of riveting tool are carried by workmen for different working positions.

A conventional rivet with screw threads in a hollow head (100) is shown in FIG 6 with a function to rivet two plates by means of the screw thread to join them firmly together.

Another conventional anchor type rivet is shown in FIG 7. The anchor rivet (200) is inserted into the holes in the plates to be joined with the two plates held by means of driving screw (201) (shown in FIG 7A).

The riveting screw might not be able to be driven all the way in at the first attempt to fasten two pieces of plate, with the same installation actions having to be "25 repeated again. A third type of rivet is the pop rivet.

"In view of the above explanation, three riveting means are commonly designed specially for the purpose of inserting a rivet cap, pop rivet or anchor rivet, each with different functions and usefulness.

30 It is an object of the invention to provide a O.V. tool with multiple functions for a workman who otherwise has to carry three different riveting means so as to meet his needs while working. To have to carry such means is heavy burden and it is expensive to buy all 35 that is needed, and it requires more room for storage.

This invention provides a multiple function riveting tool able to action a range of types of rivetlike connectors for use with sheet material and the like, and to apply a force thereto to set the connector comprising: a rotatable head means able to interchangeably mount therein one of a number of interconnection apparatus which each operatively and selectively interconnect with one type of said range of rivet-like connectors and to apply said force thereto; a hand gripping means having the rotatable head means rotatably mounted at an end thereof, said rotatable head being able to be turned about an axis, said axis being at an angle to the hand gripping means; a press bar pivotally mounted to the hand gripping means which is manually operable by gripping the tool; a transmission rod connected to the press bar and passed along, said axis to the rotatable head 2C means; a lever means pivotally mounted in the rotatable head means, pivotally interconnected at one end with the transmission rod and adapted at the other end for disconnectable operative interconnection with 25 said interconnection apparatus, effective to action said interconnection apparatus on actioning the press bar; the rotatable head means being selectively rotatable about its axis to set the apparatus at a chosen angle to the hand gripping means.

30 The tool head and handle are preferably composed by separate means. The head preferably contains a lever which connects with a transmission rod so as to permit free adjustment of the head. Another end of the lever can be connected with a sleeve by means 35 of a pulling means linked with the said sleeve and a x &r i s C .f rivet cap apparatus. A pop rivet apparatus or an anchor riveter can be connected thereto so as to achieve three functions in one, to provide a good performance and convenience for a workman in different positions.

At the ends of lever (20) are two symmetrical arms (23) with projections (24) so as to link with sleeve (11) of FIG 9 at one end in the recess .111) therein and with the transmission rod or shaft (30) at the other end in recess Two shaft holders (50) in rectangular form are screwed respectively 25 into recess (14) within flange (15) in head (10) and into recess (61) of handle Shaft holder (40) is 2 drilled with holes (42) in which is inserted small springs such as (43) and respective steel beads (44).

On the other shaft holder (50) are dimples such as (52) 30 to match spring (43) and steel beads The two shaft holders are provided with holes (45, 53), at their geometrical centre for hollow shaft (70) to go through.

The shaft (70) goes through the hole (62) on handle through the holes (45, 53) on shaft holders 35 50), through the hole (16) on the head and by means of a screw fastens them together firmly.

The transmission rod (30) goes through the hollow shaft (70) to the sleeve The transmission rod (30) has two flanges (33, 34) to form a groove (31) therebetween. The front (91) of a press-bar (90) forms a fork, with two arms (92) presenting a front segment (921) and rear segment (922) with holes (93, 94) to receive pin (644) at the front segment (921) passed through holes 641 in the handle (60) with connection collar (642) appearing outside of handle Collar (642) is fastened from outside of press-bar (90) through hole (94) on rear segment (922) through sleeve (80) on the long groove way (81) so as to make sleeve movable on press-bar In FIG 4, the tool is not actioned with the lever (90) at its utmost limited position. When changing the angle for using the riveting tool, by actioning the head to turn it, the steel bead and spring between the shaft holders are released from their dimples, either turning clockwise or in reverse. The head is easy to turn, and it can be turned through 180 degrees. The spring and bead can again slip into a dimple, the position of the head becoming that of a vertical type of riveting tool with no angle (as shown 25 on FIG FIGS 8 and 9 show a puller apparatus (300) for use with a pop type rivet. It has a rivet holder tube (301), which is screwed together with a sleeve (11) into head Two chucks (3011) are provided in a rivet 30 holder tube (301). A spring can action the two chucks to pinch the central rod. The assembly is located in the base of head (10) by screwed tube (302) on the outside, and it is connected to a fixed screw nut (303) S" and a nut (304) which can be changed in accordance with a 35 the sizes of shafts to be passed theretbrough. Pressing 6 r" -ci the press-bar (90) moves the screw (301) backward to pull a rivet (as shown in FIG 14).

Suppose that the use of the apparatus is to be changed. To change the apparatus (300), keep the sleeve (11) in head, and then mount the apparatus (400) (as shown in FIGS 10, 11) in which pull rod (401) passes through cylindrical hole and sleeve The top end of the pull rod (401) has a round female screw (4011).

A screw (4012) is used to fasten the pull rod (401) to the sleeve Its bottom end is provided with a screw thread (4013) to connect a connector of the type in FIG 6 (see FIG 15), Sleeve (402) is screwed into head (10) with lock nut (403) used with end piece (404) to enable its position to be adjusted. In use of the apparatus (400), pull rod (401) is actioned by press bar to pull rod (401) upward (as FIG 15 shows). this forces the connector to fix onto a metallic plate. The female screw (4011) is turned to release the pull rod to complete the operation.

For the purpose of applying an anchor riveter as in FIG 7, dismount the nail apparatus (300) or the cap apparatus (400), to enable the mounting of the anchor riveter (500) (as shown in FIGS 12, 13). The anchor riveter (500) consists of a draw tube (501) 25 connected to sleeve (11) with a rectangular pulling frame (5011) with a U-type opening therein (5012). On o: the outside of the head (10) is screwed a rectangular cover (502). The pulling frame (5011) is able to move up and down therein, hut it is not able to be turned.

30 Between head (10) and outside cover (502) is a screw nut (503) to lock the outside cover (502) against angular movement. Ahead of outside cover (502) is a stopper platform (504) which contains a U-shaped opening (5041).

.A rod (505) with screw head (5051) has nut (5052) linked 35 with spring (5053). The rod (505) has a cross type head (5054). The rod (505) is put into sleeve (11) through tube (501) with the cross type screw head of the rod (565) engaged with the anchor rivet. On pressing the press-bar the draw tube (501) is pulled back, and by this means, so to is the anchor rivet (as FIG 16 shows). The distance is limited and as the press-bar is released, the draw tube (501) is reinstated.

Reciprocation causes anchor rivet to fasten two pieces of plate. Turning the end (5051) drives the screw of the anchor rivet inwards for a repeat of the pulling operation to fasten two pieces of plate.

In the structures and apparatus described above, the head of the tool can be adjusted without adverse influence to the action. Moreover, changing the angle for use of the tool, that is to turn the head of this riveting tool is enabled without using any additional tool or removing parts in order to achieve a satisfactory performance.
