When the length needs to be increased, the transmission end and the force application end can be integrated into a whole only by screwing the stepped nut with the transmission rod and the force application end respectively; when the force is not required to be increased, the force application end rotates by taking the limiting rod as a rotating shaft, so that the force application end and the transmission rod form a certain included angle; the utility model discloses not only convenient collection can adapt to the operation requirement of different length moreover, great expansion the application range of traditional spanner.
Drawings
The present invention will be further described with reference to the accompanying drawings and embodiments.
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a cross-sectional view of the connection of the drive link to the force application end.
Detailed Description
The nut dismounting tool shown in the figures 1-2 comprises a transmission rod 1, a front end 2 connected with one end of the transmission rod 1 and a force application end 3 connected with the other end of the transmission rod 1, wherein an inner hole is formed in one side of the front end 2, the size of the inner hole is the same as that of a nut to be dismounted, and the inner hole is formed in one end far away from the transmission rod 1. One side of the transmission rod 1 close to the force application end 3 is provided with a U-shaped notch 4, and the U-shaped notch 4 is perpendicular to the end face of the transmission rod 1 and extends downwards for a certain distance. And a limiting rod 5 is arranged in the U-shaped notch 4. The stop lever 5 is arranged on the opposite side of the U-shaped notch 4. The force application end 3 is provided with a closed limiting groove 6 in the length direction, and the force application end 3 is partially inserted into the U-shaped notch 4 and ensures that the limiting rod 5 slides in the limiting groove 6. Preferably, the transmission rod 1 and the force application end 3 both adopt a plate-shaped structure, and the diameter of the force application end 3 is smaller than that of the transmission rod 1, so that the force application end 3 can be conveniently inserted into the U-shaped notch 4. The force application end 3 is also sleeved with a step-shaped nut 7, and the end surfaces of the step-shaped nut 7 are different in diameter. The large-diameter end of the stepped nut is close to the transmission rod 1, a second thread is arranged on the transmission rod 1 and close to the force application end 3, a first thread is arranged at the force application end 3 and close to the transmission rod 1, the large-diameter end of the stepped nut 7 can be connected with the second thread, and the small-diameter end of the nut can be connected with the first thread.
In this technical scheme, through the cooperation of gag lever post 5 and spacing groove 6 for 3 relative and the transmission shaft of exerting oneself have certain degrees of freedom, and 3 effects that can play the laborsaving arm of force of exerting oneself, also can play the extension and play the effect of transfer line 1. When the transmission rod 1 needs to be lengthened, the stepped nut 7 is respectively screwed with the transmission rod 1 and the force application end 3, and the purposes of lengthening and fixing are achieved.
Furthermore, a connecting part 8 for connecting a motor is arranged at one end of the force application end 3 away from the transmission rod 1, and the diameter of the connecting part 8 is larger than the minimum diameter of the stepped nut 7. The connecting portion 8 not only functions to connect the electrodes, but the connecting portion 8 also functions to prevent the stepped nut 7 from being separated from the force end 3.
Further, a holding part 9 is fixed on the transmission rod 1, the holding part 9 comprises an inner ring, an outer ring and rollers arranged on the inner ring and the outer ring, and the inner ring is fixed on the transmission rod 1. When the tool is used, the transmission rod 1 can rotate under the working state, so that the transmission rod 1 even the transmission rod 1 lengthened by the force application end 3 can not be fixed, and the holding part 9 is added to facilitate the fixation and the support of the transmission rod 1.
Further, when considering that the transmission rod 1 is connected with the force application end 3, the tool is long, the nut can be prevented from falling into the equipment to cause danger when being disassembled, and therefore the surface of the inner hole is provided with the magnetic layer, and the nut is convenient to adsorb. The clamping jaws 10 matched with the nut are further arranged in the inner hole, the number of the clamping jaws 10 is not less than three, the clamping jaws 10 can clamp the nut, and the nut is convenient to disassemble. In order to ensure the rigidity and the strength of the device, the transmission rod 1, the front end 2, the force application end 3, the limiting rod 5 and the stepped nut 7 are all made of 321 steel.
The above description is only a preferred embodiment of the present invention, and does not limit the scope of the present invention.
