DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0027] In order to make people have a clearer and more complete understanding of the technical solution of the present invention, here the following non-limiting features are described with the attached figures:

[0028] As is shown in FIG. 1 to FIG. 9, the one-hand handled riveter includes a housing 100 with a left handle 1 on the bottom, and aright handle 2. The mentioned left handle 1 and right handle 2 are all covered by a handle housing 3/4. The mentioned cover housing 100 is installed with a rivet head 5 and the rivet head 5 is equipped with a pull rod 6 on the rear end. Right handle 2 is connected to the pull rod 6 by the top end. Both sides of the top end of the right handle 2 is equipped with a support arm 21. The support arms 21 are connected with the pull rod 6 through a positioning shaft 7 by the top end, and the two support arms 21 are connected to a connecting rod 9 through a pin shaft 8 by the bottom end. And a connecting shaft 10 is arranged to the end of the two connecting rod 9 far away from the support arm 21. Two L-shaped connecting pieces 11 are respectively connected to two ends of the connecting shaft 10. A connecting hole 12 is arranged to the front and rear ends of the L-shaped connecting piece 11, and the connecting shaft 10 passes one of the holes 12. And the rear end of the L-shaped connecting piece 11 is connected to the fixing seat 51 on the rear end of the pull rod 6 by screw connection.

[0029] The mentioned housing 100 is connected to the rivet head 5 through thread connection by the front end, and the housing 100 is fixed to the L-shaped connecting piece 11 through screw connection by the rear end. And a lock slot 15 is arranged in the housing 100 for the fixing of L-shaped connecting piece 11.

[0030] Further, the mentioned rivet head 6 includes a fixing seat 51 fixed at the rear end of the pull rod 6 and the adjusting sleeve 52 installed at the front end of the housing 11 through thread connection. The mentioned pull rod 6 is fixed inside the central hole of the fixing seat 51 by the rear end. The mentioned adjusting sleeve 52 is equipped with a guiding nibble 53 at the front end, and the mentioned pull rod 6 is equipped with a grabbing mechanism 54 by the front end. The mentioned L-shaped connecting piece 11 has a front connecting hole 121 and a rear connecting hole 122 on the front and rear end respectively.

[0031] Operation example 1: as is shown in FIG. 1 to FIG. 4 when the mentioned connecting shaft 10 passes through the connecting hole 121 on the front end of L-shaped connecting piece 11, the connecting shaft 10 will be at the left side of the pin shaft 8. The mentioned grabbing mechanism includes the grabbing piece 641, grabbing seat 542, ejector pin 543 and return, spring 544. The mentioned grabbing piece 541 is inside the grabbing, seat 542, and the grabbing seat 542 is connected to the pull rod 6 through thread connection by the rear end and housed by the adjusting sleeve 52. The mentioned grabbing piece 541, ejector pin 543 and return spring 544 are arranged from left to right and the return spring 544 is housed in the shaft hole 61 at the front end of the pull rod 6. The mentioned ejector pin 543 presses the front end of the return spring 544. The connecting shaft 10 is equipped with the first torsion spring 13. The first torsion spring 13 is connected with the left handle 1 by one end, and its another end stretches out from the rear end of pull rod 6.

[0032] When the riveter is used, the right handle 2 will be opened to drive the pull rod 6 to move forward, and the connecting shaft 10 will keep fixed, i.e., the connecting shaft 10 serves as a fulcrum of the connecting rod 9 to allow connecting rod 9 to swing. This way, the furthest distance is formed between positioning shaft 7 and pin shaft 8 which serves as the fulcrum for the arm of force of right handle 2, and the arm of force is weakest. While, when right handle 2 is closed, the closest distance is formed between positioning shaft 7 and pin shaft 8 which serves as the fulcrum for the arm of force of right handle 2, and the arm of force is strongest. Operation above is in line with the working principle of screw riveter, so this riveter can serve as the screw riveter.

[0033] Operation example 2: as is shown in FIG. 5 to FIG. 8, when the connecting shaft 10 passes through the connecting, hole 122 on the front end of L-shaped connecting piece 11, the connecting shaft 10 will be at the right side of the pin shaft 8. The grabbing mechanism includes the nut rivet rod 54A, fixing slide sleeve 54B and spring 54C. The nut rivet rod 54A is housed in the adjusting sleeve 52 lay one end, and its another end passes through the guiding nibble 53. The fixing slide sleeve 54B is set on the front end of the connecting rod 9, and the spring 54C is set on the rear end of the fixing slide sleeve 54B and covers the pull rod 6. The pin shaft 8 is equipped with the second torsion spring 14 and the second torsion spring 14 is connected to the right handle 2 by one end, and its another end stretches into the adjusting sleeve 52.

[0034] When the riveter is used, the right handle 2 will be opened to drive the pull rod 6 to move forward and the connecting shaft 10 will keep fixed, i.e., the connecting shaft 10 serves as a fulcrum of the connecting rod 9 to allow connecting rod 9 to, swing, This way, the closest distance is formed between positioning shaft 7 and pin shaft 8 which serves as the fulcrum for the arm of force of right handle 2, and the arm of force is strongest. While, when right handle 2 is closed, the furthest distance is formed between positioning shaft 7 and pin shaft 8 which serves as the fulcrum for the arm of force of right handle 2, and the arm of force is weakest. Operation above is in line with the working principle of nut riveter, so this riveter can serve as the nut riveter.

[0035] Of course, these are only preferred examples of the invention only, and it shall not confine the patentable scope of the present invention. All products which make use of the specification and drawings of the present invention with simple modifications and equivalent structures shall be included in the scope of patent protection of the present invention.
