For example, there are other structural parts or equipment blocking the way, making it impossible to insert or rotate the torque wrench, limiting the operating space of the tool. In some narrow spaces, such as wall gaps or compact areas of mechanical equipment, the working space is extremely limited, and the torque wrench cannot enter and is difficult to use, which increases the difficulty of locking the bolts.

[0032] The utility model provides a switching mechanism.

[0033] See also Figure 1 and Figure 2 In one embodiment of the utility model, the switching mechanism includes:

When one end of the link wrench 300 is inserted into the connecting hole 210, it is limited in the connecting hole 210 of its size and cannot go deeper. When a smaller link wrench 300 is used, the link wrench 300 extends inwardly into the small-sized connecting hole 210, that is, multiple connecting holes 210 are connected through one opening, which not only saves the volume of the connecting base 200, but also meets the need to adapt to multiple link wrenches 300 of different sizes.

When one end of the connecting wrench 300 is inserted into the connecting hole 210, the magnet sheet 220 magnetically attracts the connecting wrench 300 in the connecting hole 210, so that the connection between the connecting wrench 300 and the connecting seat 200 is more stable.

[0043] In the embodiment of the present invention, a first mounting hole 130 is provided at one end of the mounting base 100 close to the connecting base 200 , and the connecting base 200 is disposed in the first mounting hole 130 to be detachably connected to the mounting base 100 .

[0044] Please refer to Figure 1 and Figure 2 The mounting base 100 includes a first mounting end 110 and a second mounting end 120.

[0050] Please refer to Figure 2 The mounting base 100 is connected to the torque wrench through the clamping piece 400. The clamping piece 400 is arranged at the end of the second connecting end 320 away from the first connecting end 310, and is used to clamp the output end of the torque wrench, so that the torque wrench applies force and transmits the force to the bolt through the mounting base 100, the connecting base 200 and the connecting wrench 300. When it is not needed in a small space, there is no need for a switching mechanism, and the clamping piece 400 and the torque wrench are disassembled for easy storage.

[0051] In an embodiment of the utility model, a second mounting hole 140 is provided at one end of the mounting seat 100 away from the connecting seat 200, and the axis of the second mounting hole 140 is perpendicular to the axis of the first mounting hole 130.

The length direction of the torque wrench is consistent with the axial direction of the first mounting hole 130 and the extension direction of the second connecting end 320, and is perpendicular to the extension direction of the first connecting end 310 and the length direction of the bolt, so as to facilitate locking the bolt when the torque wrench is turned.

[0053] In the embodiment of the present utility model, the clamping member 400 is configured as an elastic pin, which includes a spring 410 and a pin cap 420. The spring 410 is disposed in the second mounting hole 140, and one end of the spring 410 is fixedly connected to the bottom end of the second mounting hole 140, and the other end is elastically connected to the pin cap 420.

[0054] The spring pin has a first state and a second state. In the first state, the spring 410 is compressed, and the end of the mounting seat 100 away from the link wrench 300 extends into the output end of the torque wrench. The spring 410 rebounds to pop the pin cap 420 out of the through hole of the torque wrench to fix the connection between the mounting seat 100 and the torque wrench. In the second state, the pin cap 420 moves from the through hole of the torque wrench toward the spring 410 so that the spring 410 is compressed in the output end of the torque wrench to separate the mounting seat 100 from the torque wrench.

[0055] Please refer to Figure 1 and Figure 2 The clamping member 400 adopts an elastic pin, which includes a spring 410 and a pin cap 420 connected to each other. The spring 410 is arranged in the second mounting hole 140, and the other end is connected to the pin cap 420. The pin cap 420 is elastically connected to the second mounting end 120 through the spring 410. A through hole is provided at the output end of the torque wrench. When the clamping member 400 needs to be connected to the torque wrench, the pin cap 420 is pressed to compress the spring 410, so that the second mounting end 120 extends into the torque wrench. In the output end, when the pin cap 420 reaches the through hole position, the spring 410 rebounds, causing the pin cap 420 to extend outward from the through hole. At this time, the torque wrench is connected to the mounting seat 100, and the spring pin is in the first state. When the torque wrench and the mounting seat 100 do not need to be connected, the pin cap 420 is pressed inwardly at the through hole, causing the spring 410 to be compressed again, and the pin cap 420 enters the output end of the torque wrench and pulls out the mounting seat 100. At this time, the mounting seat 100 is separated from the torque wrench.
