When the first rack plate 53 is pressed downward, the gear 55 rotates counterclockwise, thereby driving the second rack plate 54 to rise, and then driving the U-shaped rod 51 to rise, thereby triggering the locking mechanism 4 to work. The locking mechanism 4 is driven to work through the meshing relationship between the gear 55 and the rack, and the transmission efficiency is higher.

[0034] In this embodiment, the driving mechanism 5 also includes: a limiting assembly 57; the limiting assembly 57 includes: a circular tube 571 arranged on one side of the rectangular tube 52 and penetrating the rectangular tube 52, a limiting rod 572 arranged horizontally in the circular tube 571, a clamping ring 573 sleeved outside the limiting rod 572 and fixedly connected to the circular tube 571, a fixing ring 574 fixed on the outer wall of the limiting rod 572, a second spring 575 fixedly connected to the clamping ring 573 and the fixing ring 574 respectively, and a limiting ring 576 sleeved on the outer wall of the limiting rod 572; the Two groups of slots 577 matched with the limit ring 576 are provided on the circular tube 571; a plurality of circular slots 531 are provided on the first rack plate 53; the limit rod 572 extends to one side outside the circular tube 571 and is fixedly provided with a knob 578; by turning the knob 578, the limit rod 572 drives the limit ring 576 to be clamped into the slot 577 close to the side of the rectangular tube 52, so that the second spring 575 applies pressure to push the free end of the limit rod 572 into any circular slot 531 of the first rack plate 53, thereby preventing the first rack plate 53 from moving.

The crossbar passes through the placement shell; One end of the connecting rod away from the cross bar is hinged to the U-shaped rod; When the U-shaped rod descends, the connecting rod drives the cross rod and the "-shaped rod to move in sequence, so that the "-shaped rod clamps the boss and presses the inner wall of the first box body against the fixing plate; The outer side of the first box is provided with a second box in an inverted U shape; The first box body and the second box body are fixedly connected by a second fixing mechanism symmetrically arranged along the terminal device body; The second fixing mechanism comprises: a mounting hole provided on the side wall of the first box body, a positioning rod passing through the mounting hole, an L-shaped plate fixed to the inner side of the first box body, and a third spring provided between the positioning rod and the L-shaped plate; The inner wall of the second box body is provided with a plurality of positioning grooves; Under the action of the third spring, the positioning rod is inserted into any positioning groove to fix the first box body and the second box body in connection; The second fixing mechanism further includes: a rectangular groove disposed on the inner wall of the first box body and below the mounting hole; A trapezoidal block is slidably connected in the rectangular groove; A vertical rod is extended from the bottom of the positioning rod; A pulley is provided at the bottom of the vertical rod; The trapezoidal block and the pressure plate are hinged via a connecting rod; When the U-shaped rod rises, it drives the pressing plate to rotate upward along the fixed plate, and the trapezoidal block rises along the rectangular groove, so that the pulley moves along the inclined surface of the trapezoidal block, thereby causing the positioning rod to escape from the positioning groove.

2. The terminal device for the e-commerce operation management platform based on big data according to claim 1, characterized in that: A plurality of buffer springs are arranged between the inner cavity of the placement shell and the U-shaped rod.

3. A method for using a terminal device for an e-commerce operation management platform based on big data, characterized in that: include: The method of use is suitable for using the terminal device for the e-commerce operation management platform based on big data as described in claim 1 or 2 to fix the terminal device body.
