Detailed ways:

As shown in the accompanying drawings 1 to 3, the utility model mainly includes an inner tube guide sleeve 1, a tooth piece positioning tube 2, a claw piece chamber 3, a propeller 4, an outer tube guide sleeve 5, a push positioning member 6 and a puller. Nail blocker 7, wherein, the inner tube guide sleeve 1 is provided with screw teeth 11 on the inner and outer diameters of the rear edge, for locking in the transmission mechanism of electric or battery-type electric drill 8, and the front inner edge of the screw teeth 11 is provided with There is a stretching chamber 12, and there are symmetrical cut-out holes 13 in the pipe body;

The tooth sheet positioning tube 2 is provided with a spring chamber 21 at the front end, and a thread 22 is provided on the outer edge of the spring chamber 21. A ring body 23 is provided behind the thread 22, and the ring body 23 is connected with the pipe body with two positioning pins 24. The rear end is provided with a symmetrical round hole 25 for inserting two tooth pieces 26, the two tooth pieces 26 are arc-shaped, the upper edge of the front end is provided with a slope 261, and the bottom edge is provided with a thread 262;

The claw piece chamber 3 is locked to the screw teeth 22 of the tooth piece positioning tube 2. Its front end is conical, and there are two duckbill-shaped claw pieces 31 inside, and a spreader 32 with a conical front end. After the spreader 32 is sleeved with a spring 33, it is placed in the spring chamber 21 of the tooth piece positioning tube 2;

The propeller 4 is used for the insertion of the aforementioned claw piece chamber 3, and its front end is provided with a thread 41, so that after being exposed through the guide sleeve 5 of the outer tube, it is locked to the propulsion positioning member 6, and its tube body is provided with a symmetrical section. Hole 42, for the locating pin 24 slippage of dental film locating tube 2;

The pull stud blocker 7 is locked to the advancing positioning member 6, and is provided with a fixing hole 71;

The outer tube guide sleeve 5 is locked to the inner tube guide sleeve 1 after inserting a spring 51;

By the combination of the aforementioned components, a rivet fixing machine is formed, so that the rivet with the rod body is inserted into the front end of the rivet blocker 7 with its rod body, and then the rivet is placed between two steel, iron, copper, aluminum plates, etc. After fixing the hole, press the propeller 4 internally to combine the tooth piece 26 of the tooth piece positioning tube 2 with the drive shaft 81 of the battery-type electric drill 8, start the battery-type electric drill 8, and drive the drive shaft 81 of the battery-type electric drill 8 The tooth piece 26 of the tooth piece positioning tube 2 makes the tooth piece positioning tube 2 be pulled inward, so that the rivets pierced in the fixing hole are squeezed at the piercing end due to the back pulling of the tooth piece positioning tube 2, forming a rivet. Fix the rivet in the two metal plates by pultruding and fixing the positioning protrusion, and after the positioning tube 2 of the tooth piece enters the expansion chamber 12 of the inner tube guide sleeve 1, the taper 82 on the transmission shaft will continue to move the two The tooth piece is stretched, so that the tooth piece 26 placed in its round hole 25 is stretched out, and then the pusher 4 and the tooth piece positioning tube 2 are returned to position instantly by the pultruded return spring 51, and the tooth piece is blocked by the pull nail. The breaker 7 cuts off the rod body, so that the assembling and fixing operation of the rivet is more convenient and practical.
