The second working mechanism 210 is configured to perform the function of the second tool 200. In the present embodiment, the second work mechanism 210 is also a chainsaw. However, in other embodiments, the functions of the first and second working

mechanisms

110, 210 may be set differently. For example, the first tool 100 is a power saw and the second tool 200 is a pruner. The second battery assembly 230 is used to provide power to the second work implement 210. The second lever 220 has the same structure as the first lever 120, and includes a third lever 221 and a fourth lever 222 coupled to the third lever 221. The second working mechanism 210 is provided at one end of the third lever 221, and the second battery module 230 and the second handle module 240 are provided at one end of the fourth lever 222. The second handle assembly 240 and the second connecting assembly have the same structure as the first handle assembly 140 and the first connecting assembly 150. The first tool 100 and the second tool 200 are different in that: the voltage of the first battery pack 130 is different from the voltage of the second battery pack 230, and the relative positional relationship between the first connection assembly 150 and the first alignment mechanism 1212 of the first tool 100 is different from the relative positional relationship between the second connection assembly and the first alignment mechanism of the second tool 200. The voltage of the first battery assembly 130 and the voltage of the second battery assembly 230 are any two different ones of 24V, 40V, and 48V. Of course, it is understood that in practical applications, the voltage of the first battery assembly 130 and the voltage of the second battery assembly 230 may be set by manufacturers according to needs. The first terminal set 1512 of the first connection assembly 150 has a first included angle α (shown in fig. 5) in the clockwise direction between the projection on the plane perpendicular to the axial direction of the first rod 121 and the projection on the plane perpendicular to the axial direction of the first rod 121 of the first alignment mechanism 1212 of the first tool 100. The projection of the first terminal set of the second connection assembly onto a plane perpendicular to the axial direction of the third shaft 221 and the projection of the first alignment mechanism of the second tool 200 onto a plane perpendicular to the axial direction of the third shaft 221 have a second included angle β in the clockwise direction (as shown in fig. 6). The angle of the first included angle is different from the angle of the second included angle. With such an arrangement, when the user mistakenly inserts the first rod 121 of the first tool 100 into the fourth rod 222 of the second tool 200, the user can find that the two cannot be inserted into each other, thereby avoiding the problem of damage to the electric tool due to the mistaken insertion. Preferably, the difference between the angle of the first included angle and the angle of the second included angle is 90 degrees.

Referring to fig. 7, the first tool 100 and the second tool 200 may further include an extension rod 300. The extension pole 300 is provided at both ends thereof with a first connector 151 and a second connector 152, respectively. Since the first and second connecting

assemblies

150 and 200 have the same structure, the first and

second tools

100 and 200 can share the extension rod 300, thereby saving design cost and warehousing cost.

Compared with the prior art, the utility model discloses first instrument 100, the same platform of second instrument 200 of tool system 1 not only can be shared to reduce design cost, manufacturing cost and storage cost, can effectively prevent moreover each other to insert between the electric tool of different voltages, and then avoided because of inserting the problem that causes the electric tool to damage by mistake.

The above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present invention.
