[0021] See also Figure 2 , the sleeve component 1 has a sleeve body 11 and a sleeve shaft 12 rotatably mounted on the sleeve body 11. In one embodiment: the sleeve body 11 has a body top wall, a body peripheral wall and a body built-in space surrounded by the body top wall and the body peripheral wall. The sleeve shaft 12 is placed in the body built-in space. The sleeve shaft 12 is perpendicular to the body top wall. The body top wall end of the sleeve shaft 12 passes through the top wall through-hole formed on the body top wall. The body top wall end of the sleeve shaft 12 is matched with the axial hole of the top wall through-hole, that is, the sleeve shaft 12 is rotatable inside the top wall through-hole. Preferably, the body top wall end of the sleeve shaft 12 has a first limiting ring groove 121. A first limiting washer 1210 is provided inside the first limiting ring groove 121. The first limiting washer 1210 abuts against the top wall of the main body to limit the displacement of the sleeve shaft 12 along the perforation of the top wall.

[0022] The non-standard bit 2 is fixed to the sleeve shaft 12 in a detachable manner. When the non-standard bit 2 is mounted on the sleeve shaft 12, the non-standard bit 2 and the sleeve shaft 12 have a common axis, and the non-standard bit 2 and the sleeve shaft 12 move synchronously. In one embodiment: the non-standard bit 2 has a bit socket. The bit socket is for the sleeve shaft 12 to be inserted. The bit socket is interference fit with the sleeve shaft 12 to achieve the detachable manner.

[0023] The transmission component 3 has a driven gear 31 and a driving gear 32 orthogonally meshed with the driven gear 31. The driven gear 31 is fixedly connected to the sleeve shaft 12. The driven gear 31 and the sleeve shaft 12 have a common axis. In one embodiment: the sleeve shaft 12 has a supporting platform 122. The supporting platform 122 is used to support the driven gear 31. Preferably, the sleeve shaft 12 has a second limiting ring groove 123. A second limiting washer 1230 is provided inside the second limiting ring groove 123. The second limiting washer 1230 and the supporting platform 122 are respectively located on opposite sides of the driven gear 31, so as to limit the displacement of the driven gear 31 along the sleeve shaft 12.

[0024] Preferably, the driving gear 32 is a spur gear, and the driven gear 31 is a face gear.

[0025] Preferably, the number of teeth of the driving gear 32 is less than that of the driven gear 31 , so that the transmission component 3 provides a reduction transmission.

[0026] See also Figure 3 , the handle component 4 has a handle operating rod 41 and a connecting sleeve 42. The handle operating rod 41 is fixedly connected to the driving gear 32 through the connecting sleeve 42. The handle operating rod 41, the connecting sleeve 42 and the driving gear 32 have a common axis. The handle operating rod 41 can drive the driving gear 32 to rotate around the axis through the connecting sleeve 42. In one embodiment: the handle operating rod 41 has an operating rod connecting portion 410. The operating rod connecting portion 410 is inside one end of the connecting sleeve 42 and the two are fixedly connected. The driving gear 32 has a gear connecting portion 320. The gear connecting portion 320 is inside the other end of the connecting sleeve 42 and the two are fixedly connected. Preferably, the operating rod connecting portion 410 has an anti-rotation feature. The purpose is to prevent the operating rod connecting portion 410 from rotating relatively inside the connecting sleeve 42. Among them, the anti-rotation feature can be a flat structure. Preferably, the gear connecting portion 320 has an anti-rotation feature. The purpose is to prevent the gear connecting portion 320 from relatively rotating inside the connecting sleeve 42. The anti-rotation feature may be a flat structure.

[0027] Preferably, the handle operating rod 41 has a grip feature 411. The purpose of providing the grip feature 411 is to increase the grip friction of the handle operating rod 41. The grip feature 411 is, for example, a friction pattern.

[0028] Preferably, the sleeve body 11 has a main body extension portion 110. The main body extension portion 110 surrounds the outside of the driving gear 32 and the connecting sleeve 42. The main body extension portion 110 is used to cover the driving gear 32 and the connecting sleeve 42. A positioning sleeve 5 is provided between the main body extension portion 110 and the gear connecting portion 320 of the driving gear 32.

[0029] When the operating space is limited and the operating object is a non-standard screw, the non-standard screw assembly tool can be used for operation. Specifically, step S1, the non-standard screw head 2 is matched with the head of the non-standard screw. Step S2, rotate the handle operating rod 41, and the handle operating rod 41 drives the driving gear 32 to rotate through the connecting sleeve. The driving gear 32 then drives the sleeve shaft 12 to rotate through the driven gear 31, and then the non-standard screw head 2 moves synchronously to tighten or loosen the non-standard screw. The non-standard screw assembly tool has a small overall height and a large length. By changing the torque direction through gear meshing, it can realize the operation of non-standard screws with limited operating space, such as the assembly and disassembly of electrical connectors.

[0030] The above only expresses the implementation mode of the present invention, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent.
