The invention discloses a 
system for testing the load durability of a handheld electric tool. The 
system comprises a 
control system, an electric 
drill load durability multi-purpose test rack, an 
angle grinder load durability multi-purpose test rack and a cooling 
system, and is characterized in that: the 
control system comprises a test circuit, a 
control circuit and a display; the electric 
drill load durability multi-purpose test rack comprises a loading device, a working 
platform test sample fixing mechanism and a stand; the working 
platform test sample fixing mechanism comprises an experimental platform, a clamping device base, a lower V-shaped pressure head, a clamping device upright board, a pressing clamp, a pair of clamping supporting bases, a right clamping support, a left clamping support, a pair of first fastening handles, a second fastening 
handle, a connecting rod and an upper V-shaped pressure head; and the cooling system is connected with the loading device of the electricdrill load durability multi-purpose test rack. The system for testing the load durability of the handheld electric tool has high 
test efficiency and high 
measurement precision, occupies small space, and is low in manufacturing cost.
