Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1-3, an auxiliary mechanism is used in production of cross allen key, including base 1, it is concrete, base 1 is base 1 that the centre gripping in the cutting process was used, spout 2 has been seted up on base 1's surface, the inside sliding connection of spout 2 has two protection pieces 3 that are the symmetric distribution, it is concrete, protection piece 3 is arc, protection piece 3's surface rotation is connected with screw rod 4, base 1's fixed surface is connected with two fixed blocks 5 that are the symmetric distribution, fixed block 5 and screw rod 4 threaded connection, the one end of screw rod 4 is equipped with fixed establishment 6.

The scheme has the following working processes:

insert the one end of cross allen key in the inside centre gripping hole of base 1, then rotate screw rod 4, screw rod 4 drives protection piece 3 through fixed block 5 and slides at base 1's top, make protection piece 3 be close to cross allen key, then leave some space, can not form the extrusion to cross allen key, the cutting process is carried out to rotatory cross allen key again, make cross allen key take shape, then take out cross allen key, when cutting the cross allen key of not unidimensional, rotate the interval of two protection pieces 3 of screw rod 4 adjustment, make cross allen key can be located between two protection pieces 3.
