[0032] On the bar lock body structure, the elastic positioning component 4 set between fork piece 2 and knob 3 can generate elastic pressing force, which not only can satisfy the normal vertical sliding of fork piece 2 and knob 3, but also can use elastic pressing force to play a certain elastic limiting action, so that the installation positioning and sliding positioning of fork piece 2 and knob 3 have relatively high stability, thereby the probability of fork piece 2 and knob 3 appearing loose can be reduced, and better use experience can be brought to users. And when the elastic positioning component 4 is placed in the notch 12 of positioning, the effect of preventing fork piece 2 and knob 3 from falling can be realized, which not only can play stable and reliable anti-falling effect, but also can greatly simplify the structure of anti-falling and greatly reduce the number of limiting components, which helps to reduce the processing and assembly difficulty, thereby helps to improve the processing and assembly efficiency, and further the bar lock body structure can have the advantages of high manufacturing efficiency and low manufacturing cost.

[0033] As Figures 2 to 10 shown, the elastic positioning assembly 4 comprises a positioning block 41 and a spring 42, the groove bottom of the limiting groove 21 is provided with a longitudinal guide groove 211, the groove bottom of the longitudinal guide groove 211 is provided with a rear limiting groove 212, one end of the spring 42 is longitudinally arranged in the rear limiting groove 212, one end of the positioning block 41 is longitudinally and slidably embedded in the longitudinal guide groove 211, and the positioning block 41 is pressed on the other end of the spring 42, the other end of the positioning block 41 is pressed on the knob 3 by the elastic action of the spring 42, and the transverse end of the positioning block 41 can enter and exit the positioning gap 12.

This not only improves the stability and reliability of the elastic positioning assembly 4 positioning the knob 3, but also makes the compression of the elastic positioning assembly 4 by the knob 3 more accurate and stable, which helps to further improve the reliability and convenience of use of the strip-shaped lock body structure.

[0035] As Figure 5 and Figure 14 shown, the rear top edge of the positioning block 41 is provided with a guide inclined surface 411 with the same inclination direction as the pressing inclined surface 32.
