The scissor jack has a base and a screw head for cooperating with a rocker arm to raise and lower the scissor jack. The base has a groove at its bottom. A fastener is provided on the rear floor corresponding to the base. The top of the fastener has a locking connector, which engages and fixes with the groove. A screw is provided on the rear floor corresponding to the screw head. The center hole of the screw head is fitted onto the screw and fixed by a screw head bolt.

[0005] In a specific embodiment of this utility model, a cavity for supporting a scissor jack is formed on the rear floor, and the fastener and screw are disposed in the cavity.

[0006] In another specific embodiment of this utility model, the slot is a U-shaped slot with an opening at one end.

[0007] In another specific embodiment of this utility model, the base forms a limiting step on the side facing the scissor jack body and around the slot.

[0008] In another specific embodiment of this utility model, the fastener is a bolt with a T-shaped longitudinal section, and the head of the bolt is the clamp connector.

[0009] In another specific embodiment of this utility model, the lead screw head bolt is provided with an internal thread that matches the screw. When the center hole of the lead screw head is fitted onto the screw, the lead screw head bolt passes through the center hole of the lead screw head from above and is screwed onto the screw, and the bolt head presses the lead screw head tightly onto the rear floor.

[0010] In a further specific embodiment of this utility model, the lead screw head bolt is further provided with a knob above the bolt head.

[0011] In a further specific embodiment of this utility model, a hexagonal nut is also provided above the knob on the lead screw head bolt.

[0012] This utility model utilizes the existing structure of scissor jacks by setting a fixing structure on the rear floor that cooperates with the base and screw head of the scissor jack. This fixing structure is simple and reasonable, has low manufacturing cost, and can reliably fix the scissor jack, avoiding damage to the scissor jack due to displacement or collision during vehicle operation, thereby effectively ensuring the safety and reliability of the scissor jack.

[0016] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. However, the description of the embodiments is not a limitation on the technical solution. Any formal but not substantive changes made based on the concept of this utility model should be considered within the protection scope of this utility model.

[0017] In the following description, all directional (or orientational) concepts involving up, down, left, right, front, and back refer to the position of the figure being described, and are intended to facilitate public understanding. Therefore, they should not be construed as a special limitation on the technical solution provided by this utility model.

[0018] See Figure 1 and Figure 2This utility model relates to a jack fixing structure, including a rear floor 1 of a vehicle compartment and a scissor jack 2 placed on the rear floor 1. The scissor jack 2 has a base 21 and a lead screw head 22 for cooperating with a rocker arm to raise and lower the scissor jack 2. A cavity 10 is formed in the rear floor 1, and the scissor jack 2 is adapted to be placed in the cavity 10.

[0019] To secure the scissor jack 2, on one hand, a fastener 11 is provided on the rear floor 1 corresponding to the base 21. The fastener 11 has a locking connector 111 at its top, and the base 21 has a locking groove 211 at its bottom. The locking connector 111 engages and is fixed with the locking groove 211. Specifically, the fastener 11 is a bolt with a T-shaped longitudinal section, and the head of the bolt is the locking connector 111. The locking groove 211 is a U-shaped groove with an opening at one end. The base 21 has a limiting step 212 on the side facing the scissor jack 2 body and around the locking groove 211 to limit the locking connector 111. On the other hand, a screw 12 is provided on the rear floor 1 corresponding to the lead screw head 22. The center hole of the lead screw head 22 is fitted onto the screw 12 and fixed by a lead screw head bolt 3. Specifically, the lead screw head bolt 3 has an internal thread 31 that matches the screw 12. When the center hole of the lead screw head 22 is fitted onto the screw 12, the lead screw head bolt 3 passes through the center hole of the lead screw head 22 from above and is screwed onto the screw 12. The bolt head 32 presses the lead screw head 22 tightly onto the rear floor 1, thereby eliminating the gap between the lead screw head 22 and the rear floor 1. To facilitate tightening the lead screw head bolt 3, a knob 33 is provided above the bolt head 32. Furthermore, a hexagonal nut 34 is provided above the knob 33, facilitating operation of the lead screw head bolt 3 using tools such as wrenches.

[0020] This invention features a fixed structure on the rear floor 1 that cooperates with the base 21 and screw head 22 of the scissor jack 2. The design is reasonable and the fixed structure is reliable, which can effectively prevent the scissor jack 2 from shifting or colliding during vehicle operation, thus ensuring the safety of the scissor jack 2 and achieving the purpose of the invention.
