The bearing 122 is a thrust needle bearing, because the head of the pull-rivet screw will press the cover 123 in the pull-rivet process, the cover 123 can rotate smoothly through the action of the bearing 122 when being pressed tightly, and the normal pull-riveting is ensured. In other embodiments, the bearing 122 can also adopt a ball bearing. A plurality of anti-skid teeth 124 are evenly distributed around the outside of the pull-rivet hole 128 in a fan shape, which ensures that the top surface of the pull-rivet nut can uniformly contact the anti-skid teeth 124 and ensures the anti-skid effect. The bearing 122 and the cover 123 are installed to the pull-rivet part 120 to form part of the wrench body 100, so that the wrench body 100 does not need to be additionally disassembled when in use, has better integrity and is more stable in use. When pull-riveting, only the pull-rivet nut and the pull-rivet screw need to be prepared, generally the pull-rivet screw with a rod structure whose diameter is smaller than that of the pull-rivet hole 128 is selected, and the head of the pull-rivet screw is larger than the through hole of the cover 123. The rod of the pull-rivet screw passes through the through hole and the pull-rivet hole 128 to pass through the pull-rivet part 120, and the rod of the pull-rivet screw and the pull-rivet hole 128 are in clearance fit and can rotate freely. Generally, the pull-rivet nut can be connected to the pull-rivet screw in advance, the part of the pull-rivet nut protruding from the bottom of the pull-rivet part 120 is screwed in, the top of the pull-rivet screw has a hexagonal groove, then the pull-rivet nut is embedded into the pull-rivet hole on the plate to be pull-riveted by holding the pull-rivet body 100, and finally the pull-rivet screw is rotated by a hexagonal wrench or an electric drill bit until the pull-riveting is completed. Compared with the structure of the previous pull-riveting by manually stacking the bearing and the gasket matched with the general wrench, the utility model has better convenience and stability, the user can hold the wrench body 100 with one hand and pull-rivet with the other hand, which is convenient for pull-riveting without complicated disassembly.
