[0053] Refer to Figures 17 to 19 , the rear locking member 32 can move between a locking state and an unlocking state. When the rear bracket 31 is moved manually by a user towards the rear end of the rear support rail 2, the convex column 321a moves along the sliding groove 221 to drive the rear locking member 32 to pivot away from the rear bracket 31, reaching the unlocking state. Then when the rear mounting member unit 33 engages the rear mounting piece 20, the rear bracket 31 is operated to move away from the rear end, the convex column 321a is reset along the sliding groove 221 to drive the rear locking member 32 to pivot towards the rear bracket 31, so that the hook portion 323 is engaged with the rear mounting piece 20, reaching the locking state. In this way, the user does not need to use tools and can fix the rear bracket module 3 to the rear mounting piece 20 only by pushing with hands.

[0054] Refer to Figures 20 to 22, the front locking member 52 can be pivoted away from the front base plate 511 by a manual operation of the user. When the front mounting member unit 53 engages with the front mounting piece 30, the front locking member 52 is pivoted toward the front base plate 511 by a manual operation of being dialed back, so that the engaging plate portion 523 engages with the front mounting piece 30, and further the front locking member 52 is positioned on the front mounting piece 30. In this way, the user does not need to use tools, and can fix the front bracket module 5 to the front mounting piece 30 only by a manual dialing method. In combination with the foregoing description, the tool-free installation slide rail fixing device 10 of the present invention can be fixedly arranged on the cabinet (not shown in the figure).

[0055] Refer to Figure 23 and Figure 24 , it should be noted that the rear mounting unit (see Figure 9 ) and the front mounting unit are the same components. Therefore, the following takes the front mounting member unit 53 and the front mounting piece 30 as examples to illustrate the engagement situation of the front mounting member unit 53 and the front mounting hole 301 of the front mounting piece 30. Each of the front mounting units can be applicable to different types of front mounting holes 301 on the front mounting piece 30. If the front mounting hole 301 is square, the front cylindrical mounting member 533 of the front mounting member unit 53 passes through the corresponding front mounting hole 301 to engage with the front mounting piece 30. Then refer to Figure 25 and 26 , if the front mounting hole 301' is a circular hole, the front cylindrical mounting member 534 of the front mounting member unit 53 passes through the corresponding front mounting hole 301' to engage with the front mounting piece 30, and the front cylindrical mounting member 533 abuts against the front mounting piece 30. Finally refer to Figure 27 Figure 28 , if the front mounting hole 301'' is a threaded hole, the front screw mounting member 531 of the front mounting member unit 53 can be screwed into the front mounting hole 301'' to engage with the front mounting piece 30. As can be seen from the above, the design of the front mounting member unit 53 can be applicable to different types of front mounting holes 301.

[0056] In summary, the tool-free installation slide rail fixing device 10 of the present invention can move between a locked state and an unlocked state by the rear locking member 32 of the rear bracket module 3. When the rear bracket 31 is operated to move toward the rear end of the rear support rail 2, the rear locking member 32 pivots away from the rear bracket 31 to reach the unlocked state. Then when the rear mounting member unit 33 engages with the rear mounting piece 20, the rear bracket 31 is operated to move away from the rear end, and the rear locking member 32 pivots toward the rear bracket 31 to engage with the rear mounting piece 20 to reach the locked state. In this way, no tools are needed, and only by pushing the rear bracket 31 can the slide rail fixing device 10 of the present invention be fixed to the cabinet. Therefore, the object of the present invention can be truly achieved.

[0057] The above are only the embodiments of the present utility model, and the scope of implementation of the present utility model cannot be limited thereby. All simple equivalent changes and modifications made according to the claims and the content of the specification of the present utility model still fall within the scope of the present utility model.
