Adopt above-mentioned technical scheme, a set of confession fixed axle male flexion of position bending type that corresponds the fixed axle at the shield, establish the holding chamber of seting up a confession spring body holding at the shield simultaneously, when the assembly, only need place the spring body in the holding intracavity, just can accomplish the central symmetry of spring body and flexion, make the assembler do not need extra to take a mental care of looking for the center and alternate at the equipment fixed axle in-process, the assembly process of simplification, it is more convenient to make lock core installation shield assemble.
The novel lock cylinder can be further set as follows: the spring body comprises a first spring body and a second spring body, the fixing part is arranged between the first spring body and the second spring body and is connected with the first spring body and the second spring body, and the other ends of the first spring body and the second spring body, which correspond to one ends of the fixing part, extend towards the dust cover to form the supporting part.
Adopt above-mentioned technical scheme, for guaranteeing the deformation power and the life of the spring body, adopt the mode of first spring body and second spring body cooperation fixed part to exert deformation return ability to the shield, the stress point sets up on the fixed part that uses first spring body and second spring body as the center, and the supporting part of the even atress in both ends simultaneously is all showing the promotion to the convenient use of lock core and the return performance and the life of shield.
The novel lock cylinder can be further set as follows: the fixing part is U-shaped.
By adopting the technical scheme, the U-shaped fixing part enables the stress to be more uniform and the use to be more stable.
The utility model has the advantages that: through setting up fixing base and positioning seat at the lock core body, make spring physical stamina through fixed axle and fixed part and lock core body firm connection, it is more convenient to make the assembly of lock core installation shield, makes the return performance and the life of shield all show the promotion through the U type fixed part that sets up first spring body and second spring body and center.
The present invention will be described in further detail with reference to the accompanying drawings and examples.

Detailed Description
As shown in fig. 1-4, a novel lock core includes lock core body 1 and key hole 11 provided on lock core body 1, lock core body 1 is provided with a dust cover 2 corresponding to one end of key hole 11, be equipped with the elastic component between dust cover 2 and lock core body 1, its characterized in that: the elastic piece comprises a spring body 3, one end of the spring body 3 corresponding to the dust cover 2 is provided with a supporting part 31, the other end is provided with a fixing part 32, the side wall of the lock cylinder body 1 corresponding to the spring body 3 is formed with a fixing seat 12 for accommodating the fixing part 32, the spring body 3 is internally provided with a fixing shaft 4 penetrating through the spring body 3, the lock cylinder body 1 is provided with a positioning seat 13 for accommodating the fixing shaft 4, the spring body 3 is abutted against the dust cover 2 through the supporting part 31, the spring body 3 is connected with the lock cylinder body 1 through the fixing part 32, the dust cover 2 is connected with the lock cylinder body 1 through the fixing shaft 4, one end of the dust cover 2 corresponding to the fixing shaft 4 is bent and formed with a bending part 21 for fixing the fixing shaft 4, one end of the dust cover 2 corresponding to the spring body 3 is provided with an accommodating cavity 22, the fixed shaft 4 penetrates through the bending portion 21 to be connected with the dust cover 2, the spring body 3 comprises a first spring body 5 and a second spring body 6, the fixed portion 32 is arranged between the first spring body 5 and the second spring body 6 and is connected with the first spring body 5 and the second spring body 6, the other ends of the first spring body 5 and the second spring body 6, corresponding to one end of the fixed portion 32, extend towards the dust cover 2 to form the supporting portion 31, and the fixed portion 32 is U-shaped.
When the lock core is assembled, the spring body 3 is only required to be placed into the accommodating cavity 22 corresponding to the dust cover 2, at the moment, the supporting portion 31 on the spring body 3 is abutted to the dust cover 2, the center of the spring body 3 is coaxial with the center of the bending portion 21, then the fixing shaft 4 is communicated with the first spring body 5 and the second spring body 6 through the bending portion 21, then the U-shaped fixing portion 32 on the assembled elastic piece is inserted into the fixing seat 12 in the lock core body 1, the two ends of the fixing shaft 4 are simultaneously placed on the positioning seats 13 at the two ends, the connection between the dust cover 2 and the lock core body 1 is completed, and the lock core can be manufactured into a finished product through a process of finally packaging the lock core cover.
In the use process, the working principle is as follows: when the key is not inserted for unlocking, the spring body 3 is in an extending state, the support part 31 supports the dustproof cover 2, so that the dustproof cover 2 completely covers the key hole 11, dust or rainwater is prevented from entering and damaging precision elements in the lock cylinder, when the key is inserted for unlocking, the key guide inclined plane pushes the dustproof cover 2 to compress the support part 31 to move towards the key hole 11, the key hole 11 under the dustproof cover 2 is exposed, the key is inserted into the key hole 11, then the lock is unlocked, the deformation of the support parts 31 arranged at the two ends of the dustproof cover 2 drives the deformation force of the first spring body 5 and the second spring body 6, after the key is pulled out, the first spring body 5 and the second spring body 6 are restored to be deformed, the deformation force of the first spring body 5 and the second spring body 6 pushes the support parts 31 to enable the dustproof cover 2 to continuously cover the key hole 11, and in the whole using process, because the support parts 31 are symmetrically arranged at the two ends of the dustproof cover 2, make shield 2 can not single atress, simultaneously because the fixed part 32 that is used for fixing in fixing base 12 sets up at the center of first spring body 5 and second spring body 6, the distribution that the deformation ability received by first spring body 5 and second spring body 6 can be even makes at the fixed part 32 of U type, spring body 3 can not pop out, also because the setting of the double spring of first spring body 5 and second spring body 6, increase the deformation ability of individual whole spring body 3, make whole lock core at life, the return performance, all there is the promotion in the deformation ability, be worth using widely.
