[0002] In the production process of products, it is often necessary to connect two workpieces with bolts, nuts and other connectors. At present, a commonly used method for disassembling and assembling connectors is to clamp the nut or bolt with your fingers, and then tighten it with a flat wrench or ratchet wrench. Another common disassembly and assembly method is to use a socket wrench for disassembly and assembly, that is, to put the nut or bolt into the disassembly and assembly position, one end of the socket wrench is inserted into the disassembly and assembly position to cooperate with the nut or bolt, and the other end of the socket wrench is used for disassembly and assembly operations. However, in daily operations, due to the structure of some workpieces, when the space at the connection is limited, the disassembly and assembly of the connector is difficult. For example, when installing the nut or bolt, the wrench is only allowed to rotate at a small angle, and the normal disassembly and assembly of the connector cannot be achieved.

[0022] As Figures 1 to 2 shown, a connecting piece disassembly and assembly device for space-limited applications includes a first handle 11, a second handle 12, and a connecting rod 13. The first handle 11 and the second handle 12 are hingedly connected through the connecting rod 13. It further includes a first support plate 21 and a transmission device. The first support plate 21 is fixedly connected to one end of the connecting rod 13. An intermediate mounting shaft 210 is provided on the first support plate 21. A first mounting shaft 41 is provided on the first handle 11. A third mounting shaft 43 is provided on the second handle 12;

[0023] The transmission device includes a first driving wheel 31, a third driving wheel 33, and an intermediate wheel 35. The first driving wheel 31, the third driving wheel 33, and the intermediate wheel 35 are connected by a belt drive. A connecting piece installation cavity 100 is formed between the first driving wheel 31, the third driving wheel 33, and the intermediate wheel 35. The intermediate wheel 35 is used to change the direction of power transmission;

[0024] The third driving wheel 33 is rotatably connected to the third mounting shaft 43, the intermediate wheel 35 is rotatably connected to the intermediate mounting shaft 210, the first mounting shaft 41 includes a first mounting shaft input end 410 and a first mounting shaft output end 411, and the first mounting shaft output end 411 is fixedly connected to the first driving wheel 31. The first mounting shaft input end 410 is used for driving connection with the output end of a pneumatic wrench or the output end of an electric wrench.

[0025] In actual operation, with the change of the size of the connecting piece to be disassembled and assembled, the total length of the belt will change within a certain range. Therefore, the belt can be made of a material with a certain stretchability for elastic compensation.

[0026] To make the output torque of the first driving wheel 31 more stable, a second mounting shaft 42 is further provided on the first handle 11, and the transmission device further includes a second driving wheel 32 which is rotatably connected to the second mounting shaft 42.

[0027] The first driving wheel 31, the second driving wheel 32, the third driving wheel 33 and the intermediate wheel 35 are connected by belt drive, and a connecting piece mounting cavity 100 is formed among the second driving wheel 32, the third driving wheel 33 and the intermediate wheel 35.

[0028] In this structure, the first driving wheel 31 outputs torque as the driving wheel, and the connecting piece mounting cavity 100 among the second driving wheel 32, the third driving wheel 33 and the intermediate wheel 35 is used to clamp the connecting piece, avoiding interference in structural functions and ensuring that the output torque of the first driving wheel 31 is more stable.

[0029] To facilitate layout and ensure reasonable transmission of the transmission device, a fourth driving wheel 34 is introduced. A fourth mounting shaft 44 is provided on the second handle 12, and the fourth driving wheel 34 is rotatably connected to the fourth mounting shaft 44. The first driving wheel 31, the second driving wheel 32, the third driving wheel 33, the fourth driving wheel 34 and the intermediate wheel 35 are connected by belt drive. Further, the first mounting shaft 41, the second mounting shaft 42, the third mounting shaft 43, the fourth mounting shaft 44 and the intermediate mounting shaft 210 are arranged in an X shape.

[0030] To strengthen the connection stability and connection strength of the intermediate mounting shaft 210, a second support plate 22 is introduced. One end of the connecting rod 13 fixedly connected to the first support plate 21 is the reference end, and the end of the connecting rod 13 away from the reference end is fixedly connected to the second support plate 22. The intermediate mounting shaft 210 is arranged on the first support plate 21 and the second support plate 22.

[0031] To clarify the connection form between the first support plate 21 and the connecting rod 13, the first support plate 21 is welded to the connecting rod 13.

[0032] Taking the disassembly of the connecting piece by the present invention as an example, a specific description is made (wherein, the counterclockwise rotation of the connecting piece is for disassembly):

[0033] When the present invention is working, first, the distance between the first handle 11 and the second handle 12 is adjusted to control the size of the connecting piece installation cavity 100, so that the workpiece abuts against the belt in the connecting piece installation cavity 100. After that, the output end of the pneumatic wrench or the output end of the electric wrench transmits power to the input end 410 of the first installation shaft;

[0034] To disassemble the connecting piece, the output end 411 of the first installation shaft drives the first driving wheel 31 to rotate clockwise. Under the action of the belt drive, the third driving wheel 33 rotates clockwise, and the intermediate wheel 35 is an intermediate transition wheel and rotates counterclockwise. Thus, the belt at the connecting piece installation cavity 100 drives the connecting piece to rotate counterclockwise to achieve the purpose of disassembly.
